  • How Climate Migration Will Reshape America. Millions will be displaced. Where will they go?

    August besieged California with a heat unseen in generations. A surge in air-conditioning broke the state’s electrical grid, leaving a population already ravaged by the coronavirus to work remotely by the dim light of their cellphones. By midmonth, the state had recorded possibly the hottest temperature ever measured on earth — 130 degrees in Death Valley — and an otherworldly storm of lightning had cracked open the sky. From Santa Cruz to Lake Tahoe, thousands of bolts of electricity exploded down onto withered grasslands and forests, some of them already hollowed out by climate-driven infestations of beetles and kiln-dried by the worst five-year drought on record. Soon, California was on fire.

    This article, the second in a series on global climate migration, is a partnership between ProPublica and The New York Times Magazine, with support from the Pulitzer Center. Read Part 1.

    Over the next two weeks, 900 blazes incinerated six times as much land as all the state’s 2019 wildfires combined, forcing 100,000 people from their homes. Three of the largest fires in history burned simultaneously in a ring around the San Francisco Bay Area. Another fire burned just 12 miles from my home in Marin County. I watched as towering plumes of smoke billowed from distant hills in all directions and air tankers crisscrossed the skies. Like many Californians, I spent those weeks worrying about what might happen next, wondering how long it would be before an inferno of 60-foot flames swept up the steep, grassy hillside on its way toward my own house, rehearsing in my mind what my family would do to escape.

    But I also had a longer-term question, about what would happen once this unprecedented fire season ended. Was it finally time to leave for good?

    I had an unusual perspective on the matter. For two years, I have been studying how climate change will influence global migration. My sense was that of all the devastating consequences of a warming planet — changing landscapes, pandemics, mass extinctions — the potential movement of hundreds of millions of climate refugees across the planet stands to be among the most important. I traveled across four countries to witness how rising temperatures were driving climate refugees away from some of the poorest and hottest parts of the world. I had also helped create an enormous computer simulation to analyze how global demographics might shift, and now I was working on a data-mapping project about migration here in the United States.

    So it was with some sense of recognition that I faced the fires these last few weeks. In recent years, summer has brought a season of fear to California, with ever-worsening wildfires closing in. But this year felt different. The hopelessness of the pattern was now clear, and the pandemic had already uprooted so many Americans. Relocation no longer seemed like such a distant prospect. Like the subjects of my reporting, climate change had found me, its indiscriminate forces erasing all semblance of normalcy. Suddenly I had to ask myself the very question I’d been asking others: Was it time to move?

    I am far from the only American facing such questions. This summer has seen more fires, more heat, more storms — all of it making life increasingly untenable in larger areas of the nation. Already, droughts regularly threaten food crops across the West, while destructive floods inundate towns and fields from the Dakotas to Maryland, collapsing dams in Michigan and raising the shorelines of the Great Lakes. Rising seas and increasingly violent hurricanes are making thousands of miles of American shoreline nearly uninhabitable. As California burned, Hurricane Laura pounded the Louisiana coast with 150-mile-an-hour winds, killing at least 25 people; it was the 12th named storm to form by that point in 2020, another record. Phoenix, meanwhile, endured 53 days of 110-degree heat — 20 more days than the previous record.

    For years, Americans have avoided confronting these changes in their own backyards. The decisions we make about where to live are distorted not just by politics that play down climate risks, but also by expensive subsidies and incentives aimed at defying nature. In much of the developing world, vulnerable people will attempt to flee the emerging perils of global warming, seeking cooler temperatures, more fresh water and safety. But here in the United States, people have largely gravitated toward environmental danger, building along coastlines from New Jersey to Florida and settling across the cloudless deserts of the Southwest.

    I wanted to know if this was beginning to change. Might Americans finally be waking up to how climate is about to transform their lives? And if so — if a great domestic relocation might be in the offing — was it possible to project where we might go? To answer these questions, I interviewed more than four dozen experts: economists and demographers, climate scientists and insurance executives, architects and urban planners, and I mapped out the danger zones that will close in on Americans over the next 30 years. The maps for the first time combined exclusive climate data from the Rhodium Group, an independent data-analytics firm; wildfire projections modeled by United States Forest Service researchers and others; and data about America’s shifting climate niches, an evolution of work first published by The Proceedings of the National Academy of Sciences last spring. (See a detailed analysis of the maps.)

    What I found was a nation on the cusp of a great transformation. Across the United States, some 162 million people — nearly one in two — will most likely experience a decline in the quality of their environment, namely more heat and less water. For 93 million of them, the changes could be particularly severe, and by 2070, our analysis suggests, if carbon emissions rise at extreme levels, at least four million Americans could find themselves living at the fringe, in places decidedly outside the ideal niche for human life. The cost of resisting the new climate reality is mounting. Florida officials have already acknowledged that defending some roadways against the sea will be unaffordable. And the nation’s federal flood-insurance program is for the first time requiring that some of its payouts be used to retreat from climate threats across the country. It will soon prove too expensive to maintain the status quo.

    Then what? One influential 2018 study, published in The Journal of the Association of Environmental and Resource Economists, suggests that one in 12 Americans in the Southern half of the country will move toward California, the Mountain West or the Northwest over the next 45 years because of climate influences alone. Such a shift in population is likely to increase poverty and widen the gulf between the rich and the poor. It will accelerate rapid, perhaps chaotic, urbanization of cities ill-equipped for the burden, testing their capacity to provide basic services and amplifying existing inequities. It will eat away at prosperity, dealing repeated economic blows to coastal, rural and Southern regions, which could in turn push entire communities to the brink of collapse. This process has already begun in rural Louisiana and coastal Georgia, where low-income and Black and Indigenous communities face environmental change on top of poor health and extreme poverty. Mobility itself, global-migration experts point out, is often a reflection of relative wealth, and as some move, many others will be left behind. Those who stay risk becoming trapped as the land and the society around them ceases to offer any more support.

    There are signs that the message is breaking through. Half of Americans now rank climate as a top political priority, up from roughly one-third in 2016, and three out of four now describe climate change as either “a crisis” or “a major problem.” This year, Democratic caucusgoers in Iowa, where tens of thousands of acres of farmland flooded in 2019, ranked climate second only to health care as an issue. A poll by researchers at Yale and George Mason Universities found that even Republicans’ views are shifting: One in three now think climate change should be declared a national emergency.

    Policymakers, having left America unprepared for what’s next, now face brutal choices about which communities to save — often at exorbitant costs — and which to sacrifice. Their decisions will almost inevitably make the nation more divided, with those worst off relegated to a nightmare future in which they are left to fend for themselves. Nor will these disruptions wait for the worst environmental changes to occur. The wave begins when individual perception of risk starts to shift, when the environmental threat reaches past the least fortunate and rattles the physical and financial security of broader, wealthier parts of the population. It begins when even places like California’s suburbs are no longer safe.

    It has already begun.

    Let’s start with some basics. Across the country, it’s going to get hot. Buffalo may feel in a few decades like Tempe, Ariz., does today, and Tempe itself will sustain 100-degree average summer temperatures by the end of the century. Extreme humidity from New Orleans to northern Wisconsin will make summers increasingly unbearable, turning otherwise seemingly survivable heat waves into debilitating health threats. Fresh water will also be in short supply, not only in the West but also in places like Florida, Georgia and Alabama, where droughts now regularly wither cotton fields. By 2040, according to federal government projections, extreme water shortages will be nearly ubiquitous west of Missouri. The Memphis Sands Aquifer, a crucial water supply for Mississippi, Tennessee, Arkansas and Louisiana, is already overdrawn by hundreds of millions of gallons a day. Much of the Ogallala Aquifer — which supplies nearly a third of the nation’s irrigation groundwater — could be gone by the end of the century.

    It can be difficult to see the challenges clearly because so many factors are in play. At least 28 million Americans are likely to face megafires like the ones we are now seeing in California, in places like Texas and Florida and Georgia. At the same time, 100 million Americans — largely in the Mississippi River Basin from Louisiana to Wisconsin — will increasingly face humidity so extreme that working outside or playing school sports could cause heatstroke. Crop yields will be decimated from Texas to Alabama and all the way north through Oklahoma and Kansas and into Nebraska.

    The challenges are so widespread and so interrelated that Americans seeking to flee one could well run into another. I live on a hilltop, 400 feet above sea level, and my home will never be touched by rising waters. But by the end of this century, if the more extreme projections of eight to 10 feet of sea-level rise come to fruition, the shoreline of San Francisco Bay will move three miles closer to my house, as it subsumes some 166 square miles of land, including a high school, a new county hospital and the store where I buy groceries. The freeway to San Francisco will need to be raised, and to the east, a new bridge will be required to connect the community of Point Richmond to the city of Berkeley. The Latino, Asian and Black communities who live in the most-vulnerable low-lying districts will be displaced first, but research from Mathew Hauer, a sociologist at Florida State University who published some of the first modeling of American climate migration in the journal Nature Climate Change in 2017, suggests that the toll will eventually be far more widespread: Nearly one in three people here in Marin County will leave, part of the roughly 700,000 who his models suggest may abandon the broader Bay Area as a result of sea-level rise alone.

    From Maine to North Carolina to Texas, rising sea levels are not just chewing up shorelines but also raising rivers and swamping the subterranean infrastructure of coastal communities, making a stable life there all but impossible. Coastal high points will be cut off from roadways, amenities and escape routes, and even far inland, saltwater will seep into underground drinking-water supplies. Eight of the nation’s 20 largest metropolitan areas — Miami, New York and Boston among them — will be profoundly altered, indirectly affecting some 50 million people. Imagine large concrete walls separating Fort Lauderdale condominiums from a beachless waterfront, or dozens of new bridges connecting the islands of Philadelphia. Not every city can spend $100 billion on a sea wall, as New York most likely will. Barrier islands? Rural areas along the coast without a strong tax base? They are likely, in the long term, unsalvageable.

    In all, Hauer projects that 13 million Americans will be forced to move away from submerged coastlines. Add to that the people contending with wildfires and other risks, and the number of Americans who might move — though difficult to predict precisely — could easily be tens of millions larger. Even 13 million climate migrants, though, would rank as the largest migration in North American history. The Great Migration — of six million Black Americans out of the South from 1916 to 1970 — transformed almost everything we know about America, from the fate of its labor movement to the shape of its cities to the sound of its music. What would it look like when twice that many people moved? What might change?

    Americans have been conditioned not to respond to geographical climate threats as people in the rest of the world do. It is natural that rural Guatemalans or subsistence farmers in Kenya, facing drought or scorching heat, would seek out someplace more stable and resilient. Even a subtle environmental change — a dry well, say — can mean life or death, and without money to address the problem, migration is often simply a question of survival.

    By comparison, Americans are richer, often much richer, and more insulated from the shocks of climate change. They are distanced from the food and water sources they depend on, and they are part of a culture that sees every problem as capable of being solved by money. So even as the average flow of the Colorado River — the water supply for 40 million Western Americans and the backbone of the nation’s vegetable and cattle farming — has declined for most of the last 33 years, the population of Nevada has doubled. At the same time, more than 1.5 million people have moved to the Phoenix metro area, despite its dependence on that same river (and the fact that temperatures there now regularly hit 115 degrees). Since Hurricane Andrew devastated Florida in 1992 — and even as that state has become a global example of the threat of sea-level rise — more than five million people have moved to Florida’s shorelines, driving a historic boom in building and real estate.

    Similar patterns are evident across the country. Census data show us how Americans move: toward heat, toward coastlines, toward drought, regardless of evidence of increasing storms and flooding and other disasters.

    The sense that money and technology can overcome nature has emboldened Americans. Where money and technology fail, though, it inevitably falls to government policies — and government subsidies — to pick up the slack. Thanks to federally subsidized canals, for example, water in part of the Desert Southwest costs less than it does in Philadelphia. The federal National Flood Insurance Program has paid to rebuild houses that have flooded six times over in the same spot. And federal agriculture aid withholds subsidies from farmers who switch to drought-resistant crops, while paying growers to replant the same ones that failed. Farmers, seed manufacturers, real estate developers and a few homeowners benefit, at least momentarily, but the gap between what the climate can destroy and what money can replace is growing.

    Perhaps no market force has proved more influential — and more misguided — than the nation’s property-insurance system. From state to state, readily available and affordable policies have made it attractive to buy or replace homes even where they are at high risk of disasters, systematically obscuring the reality of the climate threat and fooling many Americans into thinking that their decisions are safer than they actually are. Part of the problem is that most policies look only 12 months into the future, ignoring long-term trends even as insurance availability influences development and drives people’s long-term decision-making.

    Even where insurers have tried to withdraw policies or raise rates to reduce climate-related liabilities, state regulators have forced them to provide affordable coverage anyway, simply subsidizing the cost of underwriting such a risky policy or, in some cases, offering it themselves. The regulations — called Fair Access to Insurance Requirements — are justified by developers and local politicians alike as economic lifeboats “of last resort” in regions where climate change threatens to interrupt economic growth. While they do protect some entrenched and vulnerable communities, the laws also satisfy the demand of wealthier homeowners who still want to be able to buy insurance.

    At least 30 states, including Louisiana, Massachusetts, North Carolina and Texas, have developed so-called FAIR plans, and today they serve as a market backstop in the places facing the highest risks of climate-driven disasters, including coastal flooding, hurricanes and wildfires.

    In an era of climate change, though, such policies amount to a sort of shell game, meant to keep growth going even when other obvious signs and scientific research suggest that it should stop.

    That’s what happened in Florida. Hurricane Andrew reduced parts of cities to landfill and cost insurers nearly $16 billion in payouts. Many insurance companies, recognizing the likelihood that it would happen again, declined to renew policies and left the state. So the Florida Legislature created a state-run company to insure properties itself, preventing both an exodus and an economic collapse by essentially pretending that the climate vulnerabilities didn’t exist.

    As a result, Florida’s taxpayers by 2012 had assumed liabilities worth some $511 billion — more than seven times the state’s total budget — as the value of coastal property topped $2.8 trillion. Another direct hurricane risked bankrupting the state. Florida, concerned that it had taken on too much risk, has since scaled back its self-insurance plan. But the development that resulted is still in place.

    On a sweltering afternoon last October, with the skies above me full of wildfire smoke, I called Jesse Keenan, an urban-planning and climate-change specialist then at Harvard’s Graduate School of Design, who advises the federal Commodity Futures Trading Commission on market hazards from climate change. Keenan, who is now an associate professor of real estate at Tulane University’s School of Architecture, had been in the news last year for projecting where people might move to — suggesting that Duluth, Minn., for instance, should brace for a coming real estate boom as climate migrants move north. But like other scientists I’d spoken with, Keenan had been reluctant to draw conclusions about where these migrants would be driven from.

    Last fall, though, as the previous round of fires ravaged California, his phone began to ring, with private-equity investors and bankers all looking for his read on the state’s future. Their interest suggested a growing investor-grade nervousness about swiftly mounting environmental risk in the hottest real estate markets in the country. It’s an early sign, he told me, that the momentum is about to switch directions. “And once this flips,” he added, “it’s likely to flip very quickly.”

    In fact, the correction — a newfound respect for the destructive power of nature, coupled with a sudden disavowal of Americans’ appetite for reckless development — had begun two years earlier, when a frightening surge in disasters offered a jolting preview of how the climate crisis was changing the rules.

    On October 9, 2017, a wildfire blazed through the suburban blue-collar neighborhood of Coffey Park in Santa Rosa, Calif., virtually in my own backyard. I awoke to learn that more than 1,800 buildings were reduced to ashes, less than 35 miles from where I slept. Inchlong cinders had piled on my windowsills like falling snow.

    The Tubbs Fire, as it was called, shouldn’t have been possible. Coffey Park is surrounded not by vegetation but by concrete and malls and freeways. So insurers had rated it as “basically zero risk,” according to Kevin Van Leer, then a risk modeler from the global insurance liability firm Risk Management Solutions. (He now does similar work for Cape Analytics.) But Van Leer, who had spent seven years picking through the debris left by disasters to understand how insurers could anticipate — and price — the risk of their happening again, had begun to see other “impossible” fires. After a 2016 fire tornado ripped through northern Canada and a firestorm consumed Gatlinburg, Tenn., he said, “alarm bells started going off” for the insurance industry.

    What Van Leer saw when he walked through Coffey Park a week after the Tubbs Fire changed the way he would model and project fire risk forever. Typically, fire would spread along the ground, burning maybe 50 percent of structures. In Santa Rosa, more than 90 percent had been leveled. “The destruction was complete,” he told me. Van Leer determined that the fire had jumped through the forest canopy, spawning 70-mile-per-hour winds that kicked a storm of embers into the modest homes of Coffey Park, which burned at an acre a second as homes ignited spontaneously from the radiant heat. It was the kind of thing that might never have been possible if California’s autumn winds weren’t getting fiercer and drier every year, colliding with intensifying, climate-driven heat and ever-expanding development. “It’s hard to forecast something you’ve never seen before,” he said.

    For me, the awakening to imminent climate risk came with California’s rolling power blackouts last fall — an effort to pre-emptively avoid the risk of a live wire sparking a fire — which showed me that all my notional perspective about climate risk and my own life choices were on a collision course. After the first one, all the food in our refrigerator was lost. When power was interrupted six more times in three weeks, we stopped trying to keep it stocked. All around us, small fires burned. Thick smoke produced fits of coughing. Then, as now, I packed an ax and a go-bag in my car, ready to evacuate. As former Gov. Jerry Brown said, it was beginning to feel like the “new abnormal.”

    It was no surprise, then, that California’s property insurers — having watched 26 years’ worth of profits dissolve over 24 months — began dropping policies, or that California’s insurance commissioner, trying to slow the slide, placed a moratorium on insurance cancellations for parts of the state in 2020. In February, the Legislature introduced a bill compelling California to, in the words of one consumer advocacy group, “follow the lead of Florida” by mandating that insurance remain available, in this case with a requirement that homeowners first harden their properties against fire. At the same time, participation in California’s FAIR plan for catastrophic fires has grown by at least 180 percent since 2015, and in Santa Rosa, houses are being rebuilt in the very same wildfire-vulnerable zones that proved so deadly in 2017. Given that a new study projects a 20 percent increase in extreme-fire-weather days by 2035, such practices suggest a special form of climate negligence.

    It’s only a matter of time before homeowners begin to recognize the unsustainability of this approach. Market shock, when driven by the sort of cultural awakening to risk that Keenan observes, can strike a neighborhood like an infectious disease, with fear spreading doubt — and devaluation — from door to door. It happened that way in the foreclosure crisis.

    Keenan calls the practice of drawing arbitrary lending boundaries around areas of perceived environmental risk “bluelining,” and indeed many of the neighborhoods that banks are bluelining are the same as the ones that were hit by the racist redlining practice in days past. This summer, climate-data analysts at the First Street Foundation released maps showing that 70 percent more buildings in the United States were vulnerable to flood risk than previously thought; most of the underestimated risk was in low-income neighborhoods.

    Such neighborhoods see little in the way of flood-prevention investment. My Bay Area neighborhood, on the other hand, has benefited from consistent investment in efforts to defend it against the ravages of climate change. That questions of livability had reached me, here, were testament to Keenan’s belief that the bluelining phenomenon will eventually affect large majorities of equity-holding middle-class Americans too, with broad implications for the overall economy, starting in the nation’s largest state.

    Under the radar, a new class of dangerous debt — climate-distressed mortgage loans — might already be threatening the financial system. Lending data analyzed by Keenan and his co-author, Jacob Bradt, for a study published in the journal Climatic Change in June shows that small banks are liberally making loans on environmentally threatened homes, but then quickly passing them along to federal mortgage backers. At the same time, they have all but stopped lending money for the higher-end properties worth too much for the government to accept, suggesting that the banks are knowingly passing climate liabilities along to taxpayers as stranded assets.

    Once home values begin a one-way plummet, it’s easy for economists to see how entire communities spin out of control. The tax base declines and the school system and civic services falter, creating a negative feedback loop that pushes more people to leave. Rising insurance costs and the perception of risk force credit-rating agencies to downgrade towns, making it more difficult for them to issue bonds and plug the springing financial leaks. Local banks, meanwhile, keep securitizing their mortgage debt, sloughing off their own liabilities.

    Keenan, though, had a bigger point: All the structural disincentives that had built Americans’ irrational response to the climate risk were now reaching their logical endpoint. A pandemic-induced economic collapse will only heighten the vulnerabilities and speed the transition, reducing to nothing whatever thin margin of financial protection has kept people in place. Until now, the market mechanisms had essentially socialized the consequences of high-risk development. But as the costs rise — and the insurers quit, and the bankers divest, and the farm subsidies prove too wasteful, and so on — the full weight of responsibility will fall on individual people.

    And that’s when the real migration might begin.

    As I spoke with Keenan last year, I looked out my own kitchen window onto hillsides of parkland, singed brown by months of dry summer heat. This was precisely the land that my utility, Pacific Gas & Electric, had three times identified as such an imperiled tinderbox that it had to shut off power to avoid fire. It was precisely the kind of wildland-urban interface that all the studies I read blamed for heightening Californians’ exposure to climate risks. I mentioned this on the phone and then asked Keenan, “Should I be selling my house and getting — ”

    He cut me off: “Yes.”

    Americans have dealt with climate disaster before. The Dust Bowl started after the federal government expanded the Homestead Act to offer more land to settlers willing to work the marginal soil of the Great Plains. Millions took up the invitation, replacing hardy prairie grass with thirsty crops like corn, wheat and cotton. Then, entirely predictably, came the drought. From 1929 to 1934, crop yields across Texas, Oklahoma, Kansas and Missouri plunged by 60 percent, leaving farmers destitute and exposing the now-barren topsoil to dry winds and soaring temperatures. The resulting dust storms, some of them taller than skyscrapers, buried homes whole and blew as far east as Washington. The disaster propelled an exodus of some 2.5 million people, mostly to the West, where newcomers — “Okies” not just from Oklahoma but also Texas, Arkansas and Missouri — unsettled communities and competed for jobs. Colorado tried to seal its border from the climate refugees; in California, they were funneled into squalid shanty towns. Only after the migrants settled and had years to claw back a decent life did some towns bounce back stronger.

    The places migrants left behind never fully recovered. Eighty years later, Dust Bowl towns still have slower economic growth and lower per capita income than the rest of the country. Dust Bowl survivors and their children are less likely to go to college and more likely to live in poverty. Climatic change made them poor, and it has kept them poor ever since.

    A Dust Bowl event will most likely happen again. The Great Plains states today provide nearly half of the nation’s wheat, sorghum and cattle and much of its corn; the farmers and ranchers there export that food to Africa, South America and Asia. Crop yields, though, will drop sharply with every degree of warming. By 2050, researchers at the University of Chicago and the NASA Goddard Institute for Space Studies found, Dust Bowl-era yields will be the norm, even as demand for scarce water jumps by as much as 20 percent. Another extreme drought would drive near-total crop losses worse than the Dust Bowl, kneecapping the broader economy. At that point, the authors write, “abandonment is one option.”

    Projections are inherently imprecise, but the gradual changes to America’s cropland — plus the steady baking and burning and flooding — suggest that we are already witnessing a slower-forming but much larger replay of the Dust Bowl that will destroy more than just crops. In 2017, Solomon Hsiang, a climate economist at the University of California, Berkeley, led an analysis of the economic impact of climate-driven changes like rising mortality and rising energy costs, finding that the poorest counties in the United States — mostly across the South and the Southwest — will in some extreme cases face damages equal to more than a third of their gross domestic products. The 2018 National Climate Assessment also warns that the U.S. economy over all could contract by 10 percent.

    That kind of loss typically drives people toward cities, and researchers expect that trend to continue after the Covid-19 pandemic ends. In 1950, less than 65 percent of Americans lived in cities. By 2050, only 10 percent will live outside them, in part because of climatic change. By 2100, Hauer estimates, Atlanta, Orlando, Houston and Austin could each receive more than a quarter million new residents as a result of sea-level displacement alone, meaning it may be those cities — not the places that empty out — that wind up bearing the brunt of America’s reshuffling. The World Bank warns that fast-moving climate urbanization leads to rising unemployment, competition for services and deepening poverty.

    So what will happen to Atlanta — a metro area of 5.8 million people that may lose its water supply to drought and that our data also shows will face an increase in heat-driven wildfires? Hauer estimates that hundreds of thousands of climate refugees will move into the city by 2100, swelling its population and stressing its infrastructure. Atlanta — where poor transportation and water systems contributed to the state’s C+ infrastructure grade last year — already suffers greater income inequality than any other large American city, making it a virtual tinderbox for social conflict. One in 10 households earns less than $10,000 a year, and rings of extreme poverty are growing on its outskirts even as the city center grows wealthier.

    Atlanta has started bolstering its defenses against climate change, but in some cases this has only exacerbated divisions. When the city converted an old Westside rock quarry into a reservoir, part of a larger greenbelt to expand parkland, clean the air and protect against drought, the project also fueled rapid upscale growth, driving the poorest Black communities further into impoverished suburbs. That Atlanta hasn’t “fully grappled with” such challenges now, says Na’Taki Osborne Jelks, chair of the West Atlanta Watershed Alliance, means that with more people and higher temperatures, “the city might be pushed to what’s manageable.”

    So might Philadelphia, Chicago, Washington, Boston and other cities with long-neglected systems suddenly pressed to expand under increasingly adverse conditions.

    Once you accept that climate change is fast making large parts of the United States nearly uninhabitable, the future looks like this: With time, the bottom half of the country grows inhospitable, dangerous and hot. Something like a tenth of the people who live in the South and the Southwest — from South Carolina to Alabama to Texas to Southern California — decide to move north in search of a better economy and a more temperate environment. Those who stay behind are disproportionately poor and elderly.

    In these places, heat alone will cause as many as 80 additional deaths per 100,000 people — the nation’s opioid crisis, by comparison, produces 15 additional deaths per 100,000. The most affected people, meanwhile, will pay 20 percent more for energy, and their crops will yield half as much food or in some cases virtually none at all. That collective burden will drag down regional incomes by roughly 10 percent, amounting to one of the largest transfers of wealth in American history, as people who live farther north will benefit from that change and see their fortunes rise.

    The millions of people moving north will mostly head to the cities of the Northeast and Northwest, which will see their populations grow by roughly 10 percent, according to one model. Once-chilly places like Minnesota and Michigan and Vermont will become more temperate, verdant and inviting. Vast regions will prosper; just as Hsiang’s research forecast that Southern counties could see a tenth of their economy dry up, he projects that others as far as North Dakota and Minnesota will enjoy a corresponding expansion. Cities like Detroit, Rochester, Buffalo and Milwaukee will see a renaissance, with their excess capacity in infrastructure, water supplies and highways once again put to good use. One day, it’s possible that a high-speed rail line could race across the Dakotas, through Idaho’s up-and-coming wine country and the country’s new breadbasket along the Canadian border, to the megalopolis of Seattle, which by then has nearly merged with Vancouver to its north.

    Sitting in my own backyard one afternoon this summer, my wife and I talked through the implications of this looming American future. The facts were clear and increasingly foreboding. Yet there were so many intangibles — a love of nature, the busy pace of life, the high cost of moving — that conspired to keep us from leaving. Nobody wants to migrate away from home, even when an inexorable danger is inching ever closer. They do it when there is no longer any other choice.

  • Lo spot anti frontalieri. Lo spot dell’Udc svizzera contro la libera circolazione

    Voici le texte, en italien:

    Vedo una natura bella e incontaminata.
    Vedo montagne grandi e imponenti.
    Abbiamo fiumi con acque trasparenti.
    La mia mamma mi dice sempre che viviamo nel Paese più bello del mondo.
    Lo so, dobbiamo proteggere il nostro paesaggio.
    Siamo liberi e non conosciamo guerre.
    Possiamo dire apertamente ciò che pensiamo.
    Io vado a scuola e stiamo ancora abbastanza bene.
    Il mio papà mi dice sempre che la nostra cultura è molto importante. Dobbiamo difenderla e promuoverla.
    Siamo un piccolo paese per il quale il nonno ha lavorato duramente.
    Quando sarò grande mi impegnerò anch’io come lui.
    Da sempre dobbiamo fare attenzione. Molta gente crede di poter approfittare del nostro Paese.
    Sempre più persnoe vogliono venire in Svizzera. E ciò, anche se non c’è posto per tutti.
    C’è sempre più gente sulle strade. Ci sono code e tante auto ovunque.
    Il papà ha da poco perso il suo lavoro.
    Giocare davanti a casa nel quartiere è diventato meno sicuro.
    Nella mia classe, ormai solo Sara e Giorgio sono svizzeri.
    Ogni giorno la televisione parla di ladri e criminali. E ho paura quando in inverno torno da sola da scuola.
    Dappertutto ci sono uomini che gironzolano in strada e alla stazione invece che lavorare.
    Il tram è sempre pieno e non posso mai sedermi.
    Non stiamo esagerando? Perché lasciamo andare così il nostro paese?
    E’ il momento di dire basta!
    Avete la responsabilità del nostro futuro e di quello della Svizzera.
    Per favore, pensate a noi.

      Iniziativa per la limitazione: chi si batte per il clima dovrebbe votare SI

      Chi si batte per il clima dovrebbe votare SI all’iniziativa per la limitazione. Sembra un paradosso, ma in realtà non è così: è in realtà una scelta molto logica e sensata. Vediamone il motivo.

      Dall’introduzione della piena libertà di circolazione delle persone nel 2007, un numero netto di circa 75.000 persone è immigrato in Svizzera ogni anno, di cui 50.000 stranieri dell’UE. Ognuna di queste persone ha bisogno di un appartamento, un mezzo di trasporto, usa servizi statali e consuma acqua ed elettricità. Allo stesso tempo, la Svizzera dovrebbe ridurre le emissioni di CO2, smettere di costruire sui terreni coltivati e tenere sotto controllo i costi sanitari.

      Per dare abitazione al circa 1 milione di immigrati abbiamo dovuto costruire nuove abitazioni su un’area grande come 57.000 campi da calcio. Si tratta di 407 milioni di metri quadrati di natura che sono stati ricoperti di cemento. Questo include circa 454.000 nuovi appartamenti.

      Un milione di immigrati significa anche 543.000 auto in più e 789 autobus in più sulle strade e 9 miliardi di chilometri percorsi in più. Se la Svizzera dovesse raggiungere davvero entro il 2030 la popolazione di 10 milioni di abitanti, sarà necessario un ulteriore aumento della rete stradale, in quanto sempre più auto saranno in circolazione, emettendo anche ulteriore C02. L’ufficio federale dello sviluppo territoriale prevede infatti che il numero di automobili in circolazione nel 2040 aumenterà ancora del 26%.

      L’immigrazione incontrollata ha conseguenze anche sul consumo di energia. Con la Strategia energetica 2050, la Svizzera ha deciso che entro la fine del 2035 il consumo di energia pro-capite deve diminuire del 43% rispetto al 2020. Ciò per compensare l’elettricità prodotta dalle centrali nucleari, che devono essere chiuse per motivi politici. Tra l’anno di riferimento 2000 e il 2018, il consumo di energia pro-capite è diminuito del 18,8%, soprattutto a causa del progresso tecnico (motori a combustione efficienti, nuova tecnologia edilizia, lampade a LED, apparecchi a basso consumo, produzione interna di energia solare, ecc.) Nello stesso periodo, tuttavia, il consumo totale di energia in Svizzera è diminuito solo dell’1,9%. In altre parole, gli effetti di risparmio di ogni singolo svizzero sono quasi completamente assorbiti dalla crescita della popolazione a causa dell’immigrazione incontrollata

      Secondo l’accordo sul clima di Parigi, la Svizzera dovrebbe ridurre le emissioni di C02 del 50% entro il 2030. Quando la Svizzera siglò il trattato, nel 1990, aveva però 6,5 milioni di abitanti. Con la libera circolazione delle persone, nel 2030 in Svizzera vivranno 10 milioni di persone, che consumano, si spostano e producono CO2. Anche supponendo un graduale rinuncio alle automobili e una netta riduzione di emissioni nel settore industriale, con una popolazione così grande sarà impossibile per una Svizzera con oltre 10 milioni di abitanti di raggiungere l’obbiettivo previsto dell’accordo di Parigi.

      È pertanto necessario che la Svizzera torni a gestire in modo autonomo la propria immigrazione. Una Svizzera da 10 milioni di abitanti non è sostenibile né dal punto di vista economico ne dal punto di vista climatico.

  • The Next Great Migration. The Beauty and Terror of Life on the Move

    The news today is full of stories of dislocated people on the move. Wild species, too, are escaping warming seas and desiccated lands, creeping, swimming, and flying in a mass exodus from their past habitats. News media presents this scrambling of the planet’s migration patterns as unprecedented, provoking fears of the spread of disease and conflict and waves of anxiety across the Western world. On both sides of the Atlantic, experts issue alarmed predictions of millions of invading aliens, unstoppable as an advancing tsunami, and countries respond by electing anti-immigration leaders who slam closed borders that were historically porous.

    But the science and history of migration in animals, plants, and humans tell a different story. Far from being a disruptive behavior to be quelled at any cost, migration is an ancient and lifesaving response to environmental change, a biological imperative as necessary as breathing. Climate changes triggered the first human migrations out of Africa. Falling sea levels allowed our passage across the Bering Sea. Unhampered by barbed wire, migration allowed our ancestors to people the planet, catapulting us into the highest reaches of the Himalayan mountains and the most remote islands of the Pacific, creating and disseminating the biological, cultural, and social diversity that ecosystems and societies depend upon. In other words, migration is not the crisis—it is the solution.

    Conclusively tracking the history of misinformation from the 18th century through today’s anti-immigration policies, The Next Great Migration makes the case for a future in which migration is not a source of fear, but of hope.

    • Climate migration is not a problem. It’s a solution.

      Climate migration is often associated with crisis and catastrophe, but #Sonia_Shah, author of “The Next Great Migration,” wants us to think differently about migration. On The World’s weekly look at climate change solutions, The Big Fix, Shah speaks to host Marco Werman about her reporting that considers how the world would be more resilient if people were given legal safe ways to move.

    • Migration as Bio-Resilience : On Sonia Shah’s “The Next Great Migration”

      DURING THE UNUSUALLY frigid winter of 1949, a breeding pair of gray wolves crossed a frozen-over channel onto Michigan’s Isle Royale, a narrow spit of land just south of the US-Canadian maritime border in Lake Superior. Finding abundant prey, including moose, the pair had pups, starting a small lupine clan. Over the next almost 50 years, without access to the mainland, the clan grew increasingly inbred, with over half the wolves developing congenital spinal deformities and serious eye problems. As the wolf population declined — scientists even found one mother dead in her den, with seven unborn pups in her — the moose population came thundering back, gobbling up and trampling the forest’s buds and shoots. The ecosystem’s food chain now had a few broken links.

      The Isle Royale wolf population was saved, however, by a lone migrant. In 1997, a male wolf made his way to the island. Within a generation — wolf generations are a little less than five years — 56 percent of the young wolves carried the newcomer’s genes. In the years since, thanks to ongoing conservation efforts, more wolves have been brought to the island to provide enough genetic diversity not only to save the wolves but preserve the ecosystem’s new balance.

      This is just one of many examples of the bio-benefits of migratory species provided by Sonia Shah in her new book, The Next Great Migration. Hers is an original take on the oft-stultifying debate about immigration, most frequently argued over by unbending stalwarts on opposite extremes, or sometimes quibbled over by noncommittal centrists. There are now more displaced humans than ever — around one percent of the total human population — and the climate crises together with humanity’s ceaseless creep are driving an increasing number of nonhuman species to search for more welcoming climes. That half of the story is popularly understood: the world is on the move. What is less often acknowledged, and what Shah convincingly fills out, is its biological necessity. “Migration’s ecological function extends beyond the survival of the migrant itself,” she writes. “Wild migrants build the botanical scaffolding of entire ecosystems.” Besides spreading pollen and seeds — upon which the survival of many plants depend — migrants also transport genes, thus bringing genetic diversity. Migration is not only a human fact but a biological one.

      But the understanding of migration’s critical import — whether broadly biological or specifically human — has been a long time coming.

      “The idea that certain people and species belong in certain fixed places has had a long history in Western culture,” Shah writes. By its logic, “migration is by necessity a catastrophe, because it violates the natural order.” The so-called “natural order” is actually a construct that has been buoyed for millennia by a broad coalition of scientists, politicians, and other ideologically inflected cavillers. As for the word “migrant,” it didn’t even appear in the English language until the 17th century — when it was coined by Thomas Browne — and it took another hundred years before it was applied to humans. One important migrant-denialist, as Shah details, was Swedish-born naturalist Carl Linnaeus, most famous for formalizing binomial nomenclature, the modern system of classifying organisms as, say, Canis lupus or Homo sapiens.

      Shah goes beyond Linnaeus’s contribution to taxonomy — which, notably, is itself subject to critique, as when essayist Anne Fadiman describes it as a “form of mental colonising and empire-building” — to illuminate his blinkered fealty to the dominant narratives of the day. More than just falling in line, he worked to cement the alleged differences between human populations — crudely exaggerating, for instance, features of “red,” “yellow,” “black,” or “white” skinned people. He sparred with competing theorists who were beginning to propose then-revolutionary ideas — for instance, that all humans originated in and migrated out of Africa. With the concept of the “Great Chain of Being,” he toadied to the reigning theological explanation for the world being as it was; this concept hierarchically categorized, in ascending order, matter, plants, animals, peasants, clergy, noblemen, kings, and, finally, God. To support his views, Linnaeus took a trip to northern Sweden where he “studied” the indigenous Sami people, all the while complaining of the climate and the locals not speaking Swedish. Robbing them of a few native costumes, he then freely fabricated stories about their culture and origins. He later tried to give credence to biological differences between Africans and Europeans by committing to the bizarre fantasy that black women had elongated labia minora, to which he referred using the Latin term sinus pudoris. The cultural backdrop to his explanations and speculations was the generally held view that migration was an anomaly, and that people and animals lived where they belonged and belonged where they lived — and always had.

      Ignorance — deliberate, political, or simply true and profound — of the realities of even animal migration went so far as pushing scientists to hatch myriad far-fetched theories to explain, for example, where migratory birds went in the winter. Leading naturalists at the time explained some birds’ seasonal disappearance by claiming that they hibernated in lakes — a theory first proposed by Aristotle — or hid in remote caves. Driving such assumptions was, in part, the idea of a stable and God-created “harmony of nature.” When some thinkers began to question such fixed stability, Linneaus doubled down, insisting that animals inhabited their specific climes, and remained there. The implication for humans was not only that they had not migrated from Africa, but that Africans — as well as Asians and Native Americans — were biologically distinct. This kind of racial essentialism was an important structural component of what would morph into race science or eugenics. Linnaeus divided Homo sapiens into Homo sapiens europaeus (white, serious, strong), Homo sapiens asiaticus (yellow, melancholy, greedy), Homo sapiens americanus (red, ill-tempered, subjugated), and Homo sapiens afer (black, impassive, lazy), as well as Homo caudatus (inhabitants of the Antarctic globe), and even Homo monstrosus (pygmies and Patagonian giants).

      “Scientific ideas that cast migration as a form of disorder were not obscure theoretical concerns confined to esoteric academic journals,” but, Shah writes, “theoretical ballast for today’s generation of anti-immigration lobbyists and policy makers.”

      Here Shah dredges up more vile fantasies, like that of the “Malphigian layer” in the late 17th century, which claimed that Africans had an extra layer of skin consisting of “a thick, fatty black liquid of unknown provenance.” While the Malphigian layer has been roundly dismissed, such invented differences between peoples continue to bedevil medical treatment: even today, black people are presumed to be able to tolerate more pain, and so it’s perhaps hardly surprising that more black women die in childbirth.

      The idea was “that people who lived on different continents were biologically foreign to one another, a claim that would fuel centuries of xenophobia and generations of racial violence.” Or, put more simply, Linnaeus and other believed: “We belong here. They belong there.”

      ¤

      “The classifications of species as either ‘native’ or ‘alien’ is one of the organizing principles of conservation,” Shah writes, quoting a 2007 scientific study in Progress in Human Geography. The implications of that dichotomous classification are harmful to humans and nonhumans alike, setting the stage for xenophobia and white anthropomorphism. As a case in point, the son of author and conservationist Aldo Leopold recommended in 1963, that US national parks “preserve, or where necessary […] recreate the ecologic scene as viewed by the first European visitors.” The idea of a pristine, pre-colonial era presumes an ahistorical falsehood: that humans and others left no trace, or that those traces could be undone and the ecologic scene returned to a static Eden. While many indigenous cultures certainly live less disruptively within their environment, in the case of both the Americas and Australia for example, the arrival of the first Homo sapiens heralded the swift extinction of scores of native species — in the Americas, woolly mammoths, giant sloths, saber-toothed tigers, camelops, and the dire wolf. Yet the pull toward preservation persists.

      In 1999, Bill Clinton established the National Invasive Species Council, which was tasked with repelling “alien species.” This move was an outgrowth of the relatively recently created disciplines of conservation biology, restoration biology, and even invasion biology. I recall being a boy in northern Ohio and hearing of the horror and devastation promised by the zebra mussel’s inexorable encroachment into the ecosystems of the Great Lakes. One invasion biologist, writes Shah, “calculated that wild species moving freely across the planet would ravage large swaths of ecosystems. The number of land animals would drop by 65 percent, land birds by 47 percent, butterflies by 35 percent, and ocean life by 58 percent.” And while the globe is certainly losing species to extinction, blaming mobility or migration is missing the mark, and buoying up the old “myth of a sedentary planet,” as she puts it.

      For millennia, humans had hardly any idea of how some species could spread. They had neither the perspective nor technology to understand that creepy-crawlies have creeped and crawled vast distances and always been on the move, which is not, in the big picture, a bad thing. Zebra mussels, for example, were not the only, or even the greatest, threat to native clams in the Great Lakes. Besides disrupting the local ecosystems, they also contributed to those ecosystems by filtering water and becoming a new source of food for native fish and fowl. Shah notes that Canadian ecologist Mark Vellend has found that “wild newcomers generally increase species richness on a local and regional level.” Since the introduction of European species to the Americas 400 years ago, biodiversity has actually increased by 18 percent. In other words, Shah writes, “nature transgresses borders all the time.”

      In her last chapter, “The Wall,” she tackles the immunological implications of migration. While first acknowledging that certain dangers do uncontrovertibly exist, such as Europeans bringing smallpox to the Americas, or Rome spreading malaria to the outer regions of its empire, she metaphorizes xenophobia as a fever dream. To be sure, wariness of foreign pathogens may make sense, but to guide foreign policy on such grounds or let wariness morph into discrimination or violent backlash becomes, like a fever that climbs beyond what the host organism needs, “a self-destructive reaction, leading to seizures, delirium, and collapse.” It’s like a cytokine storm in the COVID-19 era. As Shah told me, “the reflexive solution to contagion — border closures, isolation, immobility — is in fact antithetical to biological resilience on a changing planet.”

      ¤

      In 2017, a solo Mexican wolf loped through the Chihuahuan Desert, heading north, following a path that other wolves, as well as humans, have traveled for thousands of years. Scientists were especially interested in this lone wolf, known as M1425, because he represented a waning population of endangered Mexican wolves dispersing genes from a tiny population in Mexico to a slightly more robust population in the United States.

      Like the Isle Royale wolves, “[i]f the two wild populations of Mexican gray wolves can find and mate with each other, the exchange of genetic material could boost recovery efforts for both populations,” a New Mexico magazine reported. But the area where M1425 crossed the international boundary is now closed off by a border wall, and the Center for Biological Diversity counts 93 species directly threatened by the proposed expansion of the wall. This is what we should be worried about.

  • How Decades of Racist Housing Policy Left Neighborhoods Sweltering

    On a hot summer’s day, the neighborhood of Gilpin quickly becomes one of the most sweltering parts of Richmond.

    There are few trees along the sidewalks to shield people from the sun’s relentless glare. More than 2,000 residents, mostly Black, live in low-income public housing that lacks central air conditioning. Many front yards are paved with concrete, which absorbs and traps heat. The ZIP code has among the highest rates of heat-related ambulance calls in the city.

    There are places like Gilpin all across the United States. In cities like Baltimore, Dallas, Denver, Miami, Portland and New York, neighborhoods that are poorer and have more residents of color can be 5 to 20 degrees Fahrenheit hotter in summer than wealthier, whiter parts of the same city.

    And there’s growing evidence that this is no coincidence. In the 20th century, local and federal officials, usually white, enacted policies that reinforced racial segregation in cities and diverted investment away from minority neighborhoods in ways that created large disparities in the urban heat environment.

    The consequences are being felt today.

    To escape the heat, Sparkle Veronica Taylor, a 40-year-old Gilpin resident, often walks with her two young boys more than a half-hour across Richmond to a tree-lined park in a wealthier neighborhood. Her local playground lacks shade, leaving the gyms and slides to bake in the sun. The trek is grueling in summer temperatures that regularly soar past 95 degrees, but it’s worth it to find a cooler play area, she said.

    “The heat gets really intense, I’m just zapped of energy by the end of the day,” said Ms. Taylor, who doesn’t own a car. “But once we get to that park, I’m struck by how green the space is. I feel calmer, better able to breathe. Walking through different neighborhoods, there’s a stark difference between places that have lots of greenery and places that don’t.”
    To understand why many cities have such large heat disparities, researchers are looking closer at historical practices like redlining.

    In the 1930s, the federal government created maps of hundreds of cities, rating the riskiness of different neighborhoods for real estate investment by grading them “best,” “still desirable,” “declining” or “hazardous.” Race played a defining role: Black and immigrant neighborhoods were typically rated “hazardous” and outlined in red, denoting a perilous place to lend money. For decades, people in redlined areas were denied access to federally backed mortgages and other credit, fueling a cycle of disinvestment.

    In 2016, these old redlining maps were digitized by historians at the University of Richmond. Researchers comparing them to today’s cities have spotted striking patterns.

    Across more than 100 cities, a recent study found, formerly redlined neighborhoods are today 5 degrees hotter in summer, on average, than areas once favored for housing loans, with some cities seeing differences as large as 12 degrees. Redlined neighborhoods, which remain lower-income and more likely to have Black or Hispanic residents, consistently have far fewer trees and parks that help cool the air. They also have more paved surfaces, such as asphalt lots or nearby highways, that absorb and radiate heat.

    “It’s uncanny how often we see this pattern,” said Vivek Shandas, a professor of urban studies and planning at Portland State University and a co-author of the study. “It tells us we really need to better understand what was going on in the past to create these land-use patterns.”

    Heat is the nation’s deadliest weather disaster, killing as many as 12,000 people a year. Now, as global warming brings ​ever more intense heat waves, cities like Richmond are ​drawing up plans to adapt​ — and confronting a historical legacy that has left communities of color far more vulnerable to heat.

    The appraisers in Richmond were transparent in their racism as they mapped the city in the 1930s as part of a Depression-era federal program to rescue the nation’s collapsing housing markets.

    Every Black neighborhood, no matter its income level, was outlined in red and deemed a “hazardous” area for housing loans. The appraisers’ notes made clear that race was a key factor in giving these neighborhoods the lowest grade.

    One part of town was outlined in yellow and rated as “declining” because, the appraisers wrote, Black families sometimes walked through.

    By contrast, white neighborhoods, described as containing “respectable people,” were often outlined in blue and green and were subsequently favored for investment.

    Richmond, like many cities, was already segregated before the 1930s by racial zoning laws and restrictive covenants that barred Black families from moving into white neighborhoods. But the redlining maps, economists have found, deepened patterns of racial inequality in cities nationwide in ways that reverberated for decades. White families could more easily get loans and federal assistance to buy homes, building wealth to pass on to their children. Black families, all too often, could not.

    That inequity likely influenced urban heat patterns, too. Neighborhoods with white homeowners had more clout to lobby city governments for tree-lined sidewalks and parks. In Black neighborhoods, homeownership declined and landlords rarely invested in green space. City planners also targeted redlined areas as cheap land for new industries, highways, warehouses and public housing, built with lots of heat-absorbing asphalt and little cooling vegetation.

    Disparities in access to housing finance “created a snowball effect that compounded over generations,” said Nathan Connolly, a historian at Johns Hopkins who helped digitize the maps. Redlining wasn’t the only factor driving racial inequality, but the maps offer a visible symbol of how federal policies codified housing discrimination.

    Congress outlawed redlining by the 1970s. But the practice has left lasting marks on cities.

    Neighborhoods to Richmond’s west that were deemed desirable for investment, outlined in green on the old maps, remain wealthier and predominantly white, with trees and parks covering 42 percent of the land. Neighborhoods in Richmond’s east and south that were once redlined are still poorer and majority Black, with much lower rates of homeownership and green space covering just 12 percent of the surface.

    These patterns largely persisted through cycles of white flight to the suburbs and, more recently, gentrification.

    Today, Richmond’s formerly redlined neighborhoods are, on average, 5 degrees hotter on a summer day than greenlined neighborhoods, satellite analyses reveal. Some of the hottest areas, like the Gilpin neighborhood, can see temperatures 15 degrees higher than wealthier, whiter parts of town.

    Even small differences in heat can be dangerous, scientists have found. During a heat wave, every one degree increase in temperature can increase the risk of dying by 2.5 percent. Higher temperatures can strain the heart and make breathing more difficult, increasing hospitalization rates for cardiac arrest and respiratory diseases like asthma. Richmond’s four hottest ZIP codes all have the city’s highest rates of heat-related emergency-room visits.

    Few neighborhoods in Richmond have been as radically reshaped as Gilpin. In the early 20th century, Gilpin was part of Jackson Ward, a thriving area known as “Black Wall Street” and the cultural heart of the city’s African-American middle class, a place where people came to see Louis Armstrong or Ella Fitzgerald perform.

    But with redlining in the 1930s, Jackson Ward fell into decline. Black residents had a tougher time obtaining mortgages and property values deteriorated. In the 1940s, the city embarked on “slum clearance” projects, razing acres of properties and replacing them with Richmond’s first segregated public housing project, Gilpin Court, a set of austere, barracks-style buildings that were not designed with heat in mind.

    A decade later, over the objections of residents, Virginia’s state government decided to build a new federal highway right through the neighborhood, destroying thousands of homes and isolating Gilpin.

    Today, Gilpin’s community pool sits empty, unfixed by the city for years. Cinder block walls bake in the sun, unshaded by trees. While city officials and local utilities have provided many people with window air-conditioners, residents said they often aren’t enough, and old electric wiring means blown fuses are common.

    “The air conditioning unit in my bedroom runs 24/7,” said Ms. Taylor, the 40-year-old mother of two. “Air circulation is poor up here on the upper level of where I live.”

    Gilpin is grappling with a mix of heat and poverty that illustrates how global warming can compound inequality.

    Sherrell Thompson, a community health worker in Gilpin, said residents have high rates of asthma, diabetes and blood pressure, all conditions that can be worsened by heat. They are also exposed to air pollution from the six-lane highway next door.

    There are no doctor’s offices nearby or grocery stores selling fresh produce, which means that people without cars face further health challenges in the heat.

    “It becomes a whole circle of issues,” Ms. Thompson said. “If you want to find any kind of healthy food, you need to walk at least a mile or catch two buses. If you have asthma but it’s 103 degrees out and you’re not feeling well enough to catch three buses to see your primary care physician, what do you do?”

    In Gilpin, the average life expectancy is 63 years. Just a short drive over the James River sits Westover Hills, a largely white, middle-income neighborhood that greets visitors with rows of massive oak trees spreading their leaves over quiet boulevards. Life expectancy there is 83 years.

    A broad array of socioeconomic factors drives this gap, but it is made worse by heat. Researchers have found that excess heat and a lack of green space can affect mental well-being and increase anxiety. Without parks or shady outdoor areas to gather, people are more likely to be isolated indoors during the summer, a dynamic worsened by the coronavirus pandemic.

    “Especially when there’s no green space nearby, the heat traps people in their homes,” said Tevin Moore, 22, who grew up in Richmond’s formerly redlined East End. “The heat definitely messes with you psychologically, people get frustrated over every little thing.”
    Climate Planners Confront Racial Inequality

    Nationwide, the pattern is consistent: Neighborhoods that were once redlined see more extreme heat in the summer than those that weren’t.

    Every city has its own story.

    In Denver, formerly redlined neighborhoods tend to have more Hispanic than Black residents today, but they remain hotter: parks were intentionally placed in whiter, wealthier neighborhoods that then blocked construction of affordable housing nearby even after racial segregation was banned. In Baltimore, polluting industries were more likely to be located near communities of color. In Portland, zoning rules allowed multifamily apartment buildings to cover the entire lot and be built without any green space, a practice the city only recently changed.

    The problem worsens as global warming increases the number of hot days nationwide.

    Today, the Richmond area can expect about 43 days per year with temperatures of at least 90 degrees. By 2089, climate models suggest, the number of very hot days could double. “All of a sudden you’re sitting on top of really unlivable temperatures,” said Jeremy Hoffman, chief scientist at the Science Museum of Virginia and a co-author of the redlining study.

    For years, cities across the United States rarely thought about racial equity when designing their climate plans, which meant that climate protection measures, like green roofs on buildings, often disproportionately benefited whiter, wealthier residents. That’s slowly starting to change.

    In Houston, officials recently passed an ordinance to prioritize disadvantaged neighborhoods for flood protection. Minneapolis and Portland are reworking zoning to allow denser, more affordable housing to be built in desirable neighborhoods. Denver has passed a new sales tax to fund parks and tree-planting, and city officials say they would like to add more green space in historically redlined areas.

    And in Richmond, a city in the midst of a major reckoning with its racist past, where crowds this summer tore down Confederate monuments and protested police brutality, officials are paying much closer attention to racial inequality as they draw up plans to adapt to global warming. The city has launched a new mapping tool that shows in detail how heat and flooding can disproportionately harm communities of color.

    “We can see that racial equity and climate equity are inherently entwined, and we need to take that into account when we’re building our capacity to prepare,” said Alicia Zatcoff, the city’s sustainability manager. “It’s a new frontier in climate action planning and there aren’t a lot of cities that have really done it yet.”

    Officials in Richmond’s sustainability office are currently engaged in an intensive listening process with neighborhoods on the front lines of global warming to hear their concerns, as they work to put racial equity at the core of their climate action and resilience plan. Doing so “can mean confronting some very uncomfortable history,” said Ms. Zatcoff. But “the more proponents there are of doing the work this way, the better off we’ll all be for it.”

    To start, the city has announced a goal of ensuring that everyone in Richmond is within a 10-minute walk of a park, working with the Science Museum of Virginia and community partners to identify city-owned properties in vulnerable neighborhoods that can be converted into green space. It’s the city’s first large-scale greening project since the 1970s.

    Green space can be transformative. Trees can cool down neighborhoods by several degrees during a heat wave, studies show, helping to lower electric bills as well as the risk of death. When planted near roads, trees can help filter air pollution. The presence of green space can even reduce stress levels for people living nearby.

    And trees have another climate benefit: Unlike paved surfaces, they can soak up water in their roots, reducing flooding during downpours.

    A few years ago, in Richmond’s formerly redlined Southside, local nonprofits and residents sought to address the lack of green space and grocery stores by building a new community garden, a triangular park with a shaded veranda and fruit trees. “Almost instantly, the garden became a community space,” said Duron Chavis of Lewis Ginter Botanical Garden, which backed the effort. “We have people holding cookouts, people doing yoga and meditation here, they can get to know their neighbors. It reduces social isolation.”

    Richmond’s long-term master plan, a draft of which was released in June, calls for increasing tree canopy in the hottest neighborhoods, redesigning buildings to increase air flow, reducing the number of paved lots and using more light-colored pavement to reflect the sun’s energy. The plan explicitly mentions redlining as one of the historical forces that has shaped the city.

    “Even people who don’t believe institutionalized racism are struck when we show them these maps,” said Cate Mingoya, director of capacity building at Groundwork USA, which has been highlighting links between redlining and heat in cities like Richmond. “We didn’t get here by accident, and we’re not going to get it fixed by accident.”

    Still, the challenges are immense. Cities often face tight budgets, particularly as revenues have declined amid the coronavirus pandemic.

    And tree-planting can be politically charged. Some researchers have warned that building new parks and planting trees in lower-income neighborhoods of color can often accelerate gentrification, displacing longtime residents. In Richmond, city officials say they are looking to address this by building additional affordable housing alongside new green space.

    Richmond’s draft master plan envisions building a park over Routes I-95 and I-64 to reconnect Gilpin with historical Jackson Ward, as well as redeveloping the public housing complex into a more walkable mixed-income neighborhood. That plan is not imminent, but local activists fear residents could eventually be priced out of this newer, greener area.

    “My worry is that they won’t build that park until the people who currently live here are removed,” said Arthur Burton, director of the Kinfolk Community Empowerment Center, who has been working to build community gardens in historically redlined areas like Gilpin.

    While many are optimistic about Richmond’s efforts to focus on racial equity, they warn there’s still much work to be done to undo disparities built up over many decades. Inequality in housing, incomes, health and education “all make a difference when we’re talking about vulnerability to climate change,” said Rob Jones, executive director of Groundwork’s Richmond chapter. “Greening the built environment is absolutely important,” he said, “but it’s only a start.”

  • Italian homes evacuated over risk of Mont Blanc glacier collapse

    Roads near #Courmayeur closed to tourists because of threat from falling #Planpincieux ice.

    Homes have been evacuated in Courmayeur in Italy’s Aosta valley, after a renewed warning that a huge portion of a Mont Blanc glacier is at risk of collapse.

    The measures were introduced on Wednesday morning after experts from the Fondazione Montagne Sicura (Safe Mountains Foundation) said 500,000 cubic metres of ice was in danger of sliding off the Planpincieux glacier on the Grandes Jorasses park.

    Some 65 people, including 50 tourists, have left homes in Val Ferret, the hamlet beneath the glacier. Roads have been closed to traffic and pedestrians.

    “We will find [alternative] solutions for residents,” Stefano Miserocchi, the mayor of Courmayeur, told the Italian news agency Ansa. “The tourists will have to find other solutions.”

    Glaciologists monitoring Planpincieux say a new section of ice is at risk of collapse. Homes were also evacuated in September last year following a warning that 250,000 cubic meters of ice could fall. The movement of the glacial mass was due to “anomalous temperature trends”, the experts said.

    The glacier has been closely monitored since 2013 to detect the speed at which the ice is melting.

    In August 2018, a heavy storm unleashed a debris flow, killing an elderly couple when their car was swept from the road that is currently closed.

    In the event of a collapse, it would take less than two minutes for the mass to reach the municipal road below.

    Safe Mountain Foundation experts are monitoring 184 glaciers in the Aosta valley region.

    There are 4,000 glaciers across the Mont Blanc massif, the highest mountain range in Europe, which straddles Italy, France and Switzerland.

    Scientists predict that if emissions continue to rise at the current rate, the Alpine glaciers could shed half of their ice by 2050.

      Une enquête de @TBIJ, avec @Disclose_ngo et le @guardian révèle que 2,3 milliards d’euros ont été versés à l’industrie de la viande et du lait par la #BERD et #IFC, deux des principales banques d’aide au développement de @Banquemondiale.

      Principal bénéficiaire des financements de l’IFC et de la BERD : la filière laitière, avec plus de 890 millions d’euros investis en 10 ans. Les filières de la #volaille et du #porc ont obtenu 445 millions d’euros chacune.

      et ses partenaires ont découvert que ces #fonds_publics ont été largement mis au service de l’expansion de #multinationales. Des géants de l’#agrobusiness qui les ont utilisés pour construire des #abattoirs et des « #méga-fermes » industrielles à travers le monde.

      Parmi les bénéficiaires se trouve des poids lourds de l’agroalimentaire français. En 2010, la BERD a pris une participation dans les filiales d’Europe de l’Est et d’Asie centrale du groupe @DanoneFR – 25,3 milliards d’euros de CA en 2019.
      En 2016, c’est le @groupe_lactalis, n°1 mondial du lait, qui obtient un prêt de 15 millions d’euros de la part de la BERD. Les fonds ont bénéficié à #Foodmaster, la filiale de Lactalis au Kazakhstan.

      A l’époque, la #BERD annonce que « ce programme permettra à #Foodmaster d’augmenter la production et la qualité des produits laitiers » locaux. Ces dernières années, #Lactalis a été impliqué dans plusieurs scandales, dont la contamination de lait infantile à la salmonelle en 2017.
      Récemment, l’IFC a validé un prêt de 48M d’euros à la société indienne Suguna, le plus gros fournisseur de volaille du pays et l’un des dix plus gros producteurs mondiaux. En 2016, une ferme de Suguna a été accusée d’utiliser un antibiotique pointé du doigt par l’OMS.

      Autant d’investissements en contradiction avec les engagements de la BERD et de l’IFC en faveur de la lutte contre le changement climatique. Incohérence d’autant plus criante que l’élevage industriel est responsable de près de 15% des émissions de gaz à effets de serre.

    • Le groupe #Carrefour complice de la #déforestation de l’#Amazonie

      Au #Brésil, les supermarchés Carrefour se fournissent en viande de #bœuf auprès d’un géant de l’agroalimentaire baptisé #Minerva. Une multinationale accusée de participer à la déforestation de l’Amazonie, et qui bénéficie du financement de la Banque mondiale.

      Chaque année, le Brésil exporte près de deux millions de tonnes de viande de boeuf. Pour assurer un tel niveau de production, l’élevage intensif est devenu la norme : partout à travers le pays, des méga-fermes dévorent la forêt amazonienne pour étendre les zones de pâturages.

      L’organisation internationale Trase, spécialisée dans l’analyse des liens entre les chaînes d’approvisionnement et la déforestation, a publié en 2019 une étude indiquant que l’industrie de la viande bovine au Brésil est responsable du massacre de 5 800 km2 de terres chaque année. Cette déforestation massive met en danger la faune et la flore, accélère les dérèglements climatiques et favorise les incendies, souvent localisés dans les zones d’élevage.

      Parmi les géants du bœuf brésilien qui sont aujourd’hui dans le viseur de plusieurs ONG : Minerva. Cette société inconnue en France est l’un des leaders de l’exportation de viande transformée, réfrigérée et congelée vers les marchés du Moyen-Orient, d’Asie ou d’Europe. Selon nos informations, l’un de ses principaux clients n’est autre que le groupe français Carrefour, qui a fait du Brésil son deuxième marché après la France.

      Fin 2019, après les incendies qui ont dévasté l’Amazonie, Noël Prioux, le directeur général de Carrefour au Brésil, s’est fendu d’une lettre à ses fournisseurs brésiliens, dont Minerva. Il souhaitait s’assurer que la viande de bœuf fournie par Minerva, mais aussi JBS et Marfrig, ne provenait pas d’élevages installés dans des zones déboisées. Quelques mois plus tôt, en juin, Carrefour s’était engagé à ce que « 100% de sa viande fraîche brésilienne » soit issue d’élevages non liés à la déforestation.

      Contacté par Disclose, Carrefour qualifie Minerva de fournisseur « occasionnel » au Brésil. Selon un responsable de la communication du groupe, Carrefour Brasil » a demandé à l’ensemble de ses fournisseurs de la filière bœuf un plan d’action pour répondre à l’engagement de lutte contre la déforestation. Dès que le groupe a connaissance de preuves de pratiques de déforestation, il cesse immédiatement d’acheter les produits dudit fournisseur. »

      https://www.youtube.com/watch?v=6ACsayFkw_Y&feature=emb_logo

      Le groupe continue pourtant à se fournir en viande bovine auprès de Minerva, mis en cause dans un rapport de Greenpeace Brésil au début du mois de juin. Selon l’ONG, l’entreprise aurait acheté des milliers de bovins à une exploitation appelée « Barra Mansa ». Laquelle est soupçonnée de se fournir auprès d’éleveurs accusés de déforestation. À l’image de la ferme de Paredão, installée dans le Parc national Serra Ricardo, dont la moitié des 4000 hectares de terrain auraient été déboisés illégalement. Barra Mansa, située à quelques kilomètres à peine, y a acheté 2 000 bovins, qui ont été achetés à leur tour par Minerva, le fournisseur de Carrefour au Brésil. Les analyses de données effectuées par Trase indiquent, elles aussi, qu’il existerait un lien direct entre les chaînes d’approvisionnement de Minerva et la déforestation de plus de 100 km2 de terres chaque année ; Minerva conteste ces conclusions.

      Minerva bénéficie du soutien de la Banque mondiale

      En décembre 2019, notre partenaire, The Bureau of Investigative Journalism (TBIJ), et le quotidien britannique The Guardian ont révélé que la Banque mondiale et son bras financier, la Société internationale financière (IFC), soutiennent directement l’activité de Minerva. Une participation financière initiée en 2013, date de la signature d’un prêt de 85 millions de dollars entre Minerva et l’IFC. Objectif affiché à l’époque : « Soutenir [le] développement [de Minerva] au Brésil, au Paraguay, en Uruguay et probablement en Colombie ». En clair, une institution d’aide au développement finance un géant mondial du bœuf soupçonné de participer à la déforestation de l’Amazonie. Le tout, avec de l’argent public.

      Selon des experts de l’ONU interrogés par le BIJ, la Banque mondiale doit absolument reconsidérer ses investissements au sein de Minerva. « Compte tenu de la crise climatique mondiale, la Banque mondiale devrait veiller à ce que tous ses investissements soient respectueux du climat et des droits de l’Homme et doit se retirer des industries qui ne respectent pas ces critères », a déclaré David Boyd, le rapporteur spécial des Nations Unies pour les droits de l’homme et l’environnement. Une position également défendue par son prédécesseur, le professeur de droit international John Knox : « Le financement international de projets contribuant à la déforestation et la détérioration du climat est totalement inexcusable ».

      Contactée, l’IFC explique avoir « investi dans Minerva afin de promouvoir une croissance pérenne (…) dans le but de créer une industrie bovine plus durable ». L’organisation assure que sa participation dans l’entreprise a permis à Minerva de prendre « des mesures pour améliorer la traçabilité de son approvisionnement auprès de ses fournisseurs directs », précisant qu’aujourd’hui « 100 % de ses achats directs proviennent de zones qui n’ont pas été déforestées. » Quid, dès lors, des fournisseurs indirects ? Ceux qui font naître et élèvent les bovins, avant qu’ils n’arrivent aux ranchs qui les enverront à l’abattoir ? Ils constituent de fait le premier maillon de la chaîne d’approvisionnement.

      Taciano Custódio, responsable du développement durable de Minerva, reconnaît lui-même qu’ « à ce jour, aucun des acteurs de l’industrie n’est en mesure de localiser les fournisseurs indirects ». Il en rejette la faute sur l’administration brésilienne et l’absence de réglementation en la matière, tout en justifiant la déforestation : « Les pays d’Amérique du Sud possèdent encore un grand pourcentage de forêts et de terres non défrichées qui peuvent être exploitées légalement et de manière durable. Certains pays invoquent notamment la nécessité d’agrandir leur territoire de production afin de pouvoir développer la santé et l’éducation publiques et investir dans des infrastructures. ».

      Depuis le début de l’année 2020, plus de 12 000km2 de forêt ont disparu. Soit une augmentation de 55% par rapport à l’année dernière sur la même période.

  • Quand la #banque_centrale donne gratuitement de l’argent aux grandes #banques_commerciales au lieu de financer la #reconstruction_écologique
    https://www.institut-rousseau.fr/quand-la-banque-centrale-donne-gratuitement-de-largent-aux-grandes

    Et toutes ces sommes sont empruntées à taux négatifs, à – 1 % ! Ce qui signifie que la banque centrale donne littéralement de l’argent aux banques privées pour qu’elles daignent venir lui emprunter des liquidités, alors même qu’on refuse toujours de financer directement les États ou d’annuler les #dettes_publiques qu’elle détient. D’ailleurs, les conditions à atteindre pour bénéficier du taux de – 1 % ont été considérablement assouplies. Auparavant, les banques devaient apporter la preuve qu’elles avaient accru leur portefeuille de prêts aux entreprises et aux ménages pour profiter du coût le plus favorable. Dans le cadre de cette nouvelle opération, elles peuvent se contenter de le maintenir à leur niveau d’avant la crise du Covid. Et on rajoute à cela que si jamais des emprunteurs font défaut, il y a désormais de bonnes chances pour que les banques soient remboursées directement par le Gouvernement. Rien que pour la première année de leur emprunt, ce sont donc 13 milliards d’euros qui seront versés gratuitement aux banques par la création monétaire ex nihilo de la banque centrale. Sur trois ans, près de 40 milliards d’euros seront ainsi offerts. N’a-t-on pas mieux à faire avec 40 milliards d’euros, comme lutter contre le #changement_climatique par exemple ?

    Dans le monde des économistes orthodoxes, personne ou presque ne s’inquiète de la « crédibilité » de l’action de la banque centrale, du risque d’#inflation sur les #marchés_financiers (c’est-à-dire de #bulles_financières que ce type d’action ne manquera pas d’engendrer), ou bien de l’impact sur les fonds propres de la banque centrale (qui pour le coup est absolument certain contrairement aux opérations d’annulation de dettes publiques détenues par la banque centrale). En 2008, nous avions été choqués de la socialisation des pertes et la privatisation des profits sans rien faire, sinon des réformes cosmétiques. Nous avons désormais fait mieux en passant dans une phase de couverture intégrale des pertes et de fabrication artificielle des profits grâce à une banque centrale dont l’indépendance farouche vis-à-vis des États n’a d’égale que sa complaisance et sa dépendance à l’égard du système financier privé.

    Si la proposition, portée notamment par l’Institut Rousseau, d’annulation des dettes publiques détenues par la BCE a suscité une levée de boucliers de la part d’un petit groupe d’économistes néolibéraux confortablement installés dans leurs certitudes, leur silence concernant les dérives de ces pratiques est en revanche assourdissant. À croire que l’indignation ne naît que lorsqu’on tente de rétablir la monnaie comme l’instrument d’émancipation sociale et politique qu’elle n’aurait jamais dû cesser d’être, mais pas quand la #création_monétaire de la banque centrale vise à faire des cadeaux perpétuels aux #banques_privées sans aucune contrepartie ou presque.

    C’est pourquoi il importe de rappeler une nouvelle fois que l’indépendance des banques centrales n’a rien de naturel et est foncièrement antidémocratique. Elle ne repose que sur une décision politique funeste, désormais inscrite dans les traités, qui la coupe du pouvoir délibérant de la collectivité et la place sous la coupe des marchés financiers. Cette architecture monétaire et financière relève entièrement d’un choix politique et idéologique qui repose sur l’idée que la monnaie doit être neutre, soustraite aux mains de politiques nécessairement démagogiques et confiée entièrement aux marchés privés qui nous conduiront vers la prospérité grâce aux vertus naturelles de la main invisible et de la libre-concurrence. Il est donc temps de comprendre que le sérieux et la raison ne sont pas du côté de ceux qui, par suivisme ou par intérêt, défendent ce type de pensée magique et nous imposent les sacrifices inutiles qui l’accompagnent, tout en bénéficiant allégrement de la création monétaire qu’ils dénoncent.

      It probably won’t work, at least how you would hope. We’re in the age of legal realism, in which power and money matters more than the letter of the law. And you probably shouldn’t call it ‘open source’ because the OSI, the organization that controls the term (somehow?) says that ethos licensing isn’t open source.

  • Les réseaux sociaux russes, lanceurs d’alerte de la catastrophe de #Norilsk

    Le 3 juin, le président russe Vladimir Poutine a déclaré l’#état_d’urgence au niveau fédéral, après la fuite le 29 mai d’au moins 20 000 tonnes de #diesel dans une rivière du Grand Nord. La catastrophe a été provoquée par l’effondrement d’un réservoir de la #centrale_thermique de Norilsk, en #Sibérie orientale.

    À Vladimir Potanine, dirigeant de l’entreprise en cause Norilsk Nickel (premier producteur de nickel au monde), le chef du Kremlin a adressé les reproches suivants : « Pourquoi les agences gouvernementales n’ont-elles été mises au courant que deux jours après les faits ? Allons-nous apprendre les situations d’urgence sur les réseaux sociaux ? »

    Ce sont en effet des vidéos postées par des citoyens sur les #réseaux_sociaux qui ont alerté les autorités sur le drame. Depuis des années en Russie, ils constituent un canal de communication important pour les experts et les écologistes qui cherchent à alerter sur les #catastrophes_industrielles et les conséquences du #changement_climatique. Cela offre à la #société_civile une mine d’informations et un espace où s’expriment les critiques sur le manque d’action et d’anticipation de l’État et des entreprises face à ces situations d’urgence.

    Cette nouvelle catastrophe a suscité grâce aux réseaux une attention médiatique nouvelle, pour ces régions isolées où des drames écologiques se jouent régulièrement.
    https://www.youtube.com/watch?v=0kakLGwXGzM&feature=emb_logo

    Un temps précieux perdu

    Précisons que la catastrophe du 29 mai est particulièrement préoccupante. Plus encore que le pétrole, le diesel est extrêmement toxique et les sauveteurs de #Mourmansk, spécialisés dans la #dépollution, ne sont arrivés sur place que 40 heures après la catastrophe du fait du délai entre la survenue de l’#effondrement et l’alerte. Un retard qui n’a permis de récupérer qu’une infime quantité de diesel.

    La majeure partie du carburant a coulé au fond de la rivière #Ambarnaïa et déjà atteint le #lac_Piassino. Le #carburant est en train de se dissoudre dans l’#eau ce qui rend sa collecte difficile et il n’est pas non plus envisageable de le brûler, ce qui libérerait des substances toxiques en quantité trop importante.

    L’#Arctique ne compte par ailleurs ni route ni réservoir pour collecter les #déchets. En construire près des zones polluées est impossible, la #toundra étant marécageuse et impraticable. Les sites de déversement ne sont donc atteignables que par hélicoptère et l’été dans l’Arctique étant très court, le temps presse.

    Rappelons que le #Grand_Nord fait continuellement la triste expérience de la #pollution par le #pétrole, lors de son exploitation et de son acheminement.

    Succession de catastrophes

    La région de Norilsk n’en est en effet pas à son premier #désastre_écologique. Dans cette zone industrielle, les #rivières revêtent déjà toutes les couleurs de l’arc-en-ciel, non seulement à cause des #hydrocarbures mais également d’autres #activités_industrielles (rejets de #métaux_lourds et de #dioxyde_de_souffre de la #mine de #nickel et du centre industriel métallurgique).

    Convoquée à l’occasion de la fuite massive, la mémoire d’Internet met en lumière les catastrophes passées. En 2016, la rivière #Daldykan à Norilsk avait elle aussi pris un aspect rouge. Les autorités locales et fédérales et les médias locaux avaient alors gardé le silence pendant plusieurs jours. Après avoir nié l’accident, #Norilsk_Nickel avait fini par l’admettre une semaine plus tard tout en assurant que le phénomène ne présentait aucun danger pour l’#environnement. Sous la pression de la société civile locale, images à l’appui, les autorités avaient été poussées à ouvrir une enquête.

    Et il y a seulement trois mois, le 4 mars, dans la même région, près de 100 tonnes de diesel se répandaient dans les glaces de la rivière #Angara après la rupture d’un #pipeline.

    Ces catastrophes lointaines, qui surviennent dans des régions peu peuplées, n’attirent généralement pas l’attention médiatique. Celle de Norilsk, par son ampleur et sa portée internationale, suscite une prise de conscience nouvelle.

    État incapable et entreprises négligentes

    La catastrophe réveille les débats sur les réseaux sociaux russes autour de la gestion du risque environnemental et l’absence totale de responsabilisation des entreprises polluantes en Russie. Les principes de pollueur-payeur, de prévention et de précaution, si difficiles à faire appliquer en France, n’y existent tout simplement pas.

    Les monstres de l’industrie (pétrole, gaz naturel et divers métaux) échappent au contrôle de l’État. Pour preuve, les services d’inspection fédéraux n’ont même pas été admis sur place par les vigiles de Norilsk Nickel, comme l’a déploré Svetlana Radionova, la responsable du Service fédéral de contrôle des ressources naturelles et de la protection de l’environnement, le 30 mai dernier sur son compte Facebook.

    Cette fuite constitue pourtant la plus grande catastrophe environnementale qu’a connue l’Arctique. Dans cette région, la #décomposition_biologique des produits issus du pétrole est extrêmement lente et pourrait prendre au moins 10 ans. Un drame qui aura des répercussions sur les milieux arctiques, déjà très vulnérables : comme l’expliquait en 2018 la géographe Yvette Vaguet,« Les #lichens peuvent nécessiter jusqu’à 30 ans pour repousser et un saule nain peut ici être vieux d’un siècle ».

    Fonte du #permafrost et catastrophes industrielles

    Depuis des années, des chercheurs spécialistes de l’Arctique tentent d’alerter via les réseaux sociaux, faute d’une prise de conscience dans la classe politique. On ne compte plus les dommages causés par le changement climatique aux écosystèmes : les feux de forêt se multiplient, la couverture neigeuse diminue fortement et l’épaisseur de la glace dans la #mer_de_Kara rétrécit de plus en plus rapidement – elle a commencé cette année à fondre un mois plus tôt que d’habitude.

    Les régions de Russie à permafrost, cette combinaison de glace et de terre qui représente environ 60 % de la masse terrestre du pays, ne peuvent plus supporter la même charge que dans les années 1980. Or la plupart des structures construites à l’époque soviétique pour l’exploitation des ressources n’ont jamais été remplacées, alors même que le problème est connu de longue date.

    Dans la région de Norilsk, la fonte du permafrost entraîne donc l’affaissement des installations, comme l’avait déjà alerté un rapport du ministère des Ressources naturelles et de l’Environnement, publié en 2018. La catastrophe du 29 mai en est la conséquence directe, provoquée par l’effondrement d’un des piliers du réservoir que la compagnie n’avait jamais remplacé depuis 1985.

    La #faune et la #flore du Grand Nord menacées

    Parmi les avertissements adressés par les chercheurs sur les réseaux sociaux, une préoccupation revient régulièrement, celle des effets du changement climatique et des activités humaines sur la faune et la flore du Grand Nord.

    La région de #Taimyr, dont Norilsk est la capitale, a déjà déploré la disparition d’un emblématique renne sauvage : en l’espace de 15 ans, 40 % des animaux du plus grand troupeau sauvage de rennes au monde ont disparu.

    En cette période de crue printanière, le diesel répandu par la catastrophe va imprégner tous les pâturages de #cerfs de la plaine inondable. Or la #chasse – au #cerf notamment – constitue avec la #pêche le principal moyen de subsistance des peuples indigènes de Taimyr. Sur les sites et les pages Internet où échangent ces populations, l’inquiétude est palpable. Gennady Shchukin, chef de la communauté #Dolgan, militant et adjoint du conseil de district #Dolgano-Nenets, a d’ailleurs publié sur les réseaux sociaux une lettre adressée au président Poutine et à différents hauts fonctionnaires pour réclamer une enquête publique et transparente et faire part de sa préoccupation.

    « Les cerfs ne survivront pas lorsqu’ils traverseront la rivière. Le diesel se déposera sur le corps de l’animal. Il ne survivra pas à l’hiver. L’animal ne pourra pas se débarrasser de ce film, et il ne pourra pas se réchauffer. Nous ne pourrons pas non plus vendre cette viande car elle aura une odeur de diesel. Les cerfs mourront et se décomposeront dans cette mer de diesel, dans la toundra. Le même sort attend les oiseaux et les poissons de l’Arctique. »

    Une autre voix, celle d’Alexander Kolotov, président de l’ONG écologiste Plotina.Net, résume ainsi la situation.

    « Je pense qu’un déversement de diesel de cette ampleur montre que nous ne disposons pas actuellement de technologies suffisamment sophistiquées pour faire face à des catastrophes d’une telle ampleur. Et cela soulève la question suivante : dans quelle mesure devrions-nous continuer à envahir et vouloir dompter l’Arctique, si nous ne pouvons faire face à la catastrophe ? »

    Sur l’Internet russe, des informations circulent, des alertes sont lancées, des critiques sont adressées. On y découvre effectivement les situations d’urgence… mais aussi l’histoire des catastrophes industrielles d’une région, leurs effets à long terme et l’incurie de l’État en la matière.

  • Quand les villes suent

    Le changement climatique provoque de plus en plus de vagues de #chaleur. Ce sont les villes qui en souffrent le plus. En été, elles enregistrent davantage de jours de #canicule et de #nuits_tropicales. Pour se rafraîchir, elles misent sur la #végétalisation, la multiplication des #plans_d’eau ouverts et une bonne #circulation_de_l’air dans les quartiers.

    En été, lorsqu’il fait chaud, les jets d’eau de la Place fédérale de Berne ravissent autant les touristes que les locaux. Devant les grandes façades de grès du Palais fédéral et de la Banque nationale, des enfants s’ébattent entre les 26 jets d’eau qui représentent chacun un canton suisse. Trempés jusqu’aux os, ils s’allongent à plat ventre sur le sol en pierre chaud pour se faire sécher. Aux terrasses des restaurants, au bord de l’Aar et aux stands de glaces, on respire une atmosphère méditerranéenne. Et c’est un fait : du point de vue climatique, les villes de l’hémisphère nord deviennent de plus en plus méridionales. Une étude de chercheurs de l’ETH de Zurich, qui ont analysé les changements climatiques prévus ces 30 prochaines années pour 520 capitales, le démontre. En 2050, le climat de Berne pourrait être le même que celui de Milan aujourd’hui. Londres lorgnera du côté de Barcelone, Stockholm de Budapest et Madrid de Marrakech.

    En Suisse, les derniers scénarios climatiques prévoient une hausse des températures estivales de 0,9 à 2,5 degrés Celsius. Par conséquent, le nombre de jours de canicule (dès 30°C) continuera d’augmenter, mettant à rude épreuve surtout les villes, qui deviennent de véritables #îlots_de_chaleur. Enfilades de maisons sans #ombre et #places_asphaltées réchauffent fortement l’atmosphère. La nuit, l’air refroidit peu, et les « nuits tropicales » (lorsque le thermomètre ne descend pas au-dessous de 20°C) se multiplient.

    Des #arbres plutôt que des #climatiseurs

    En Suisse, le chef-lieu du canton du Valais, #Sion, est particulièrement touché par la hausse de la chaleur : dans aucune autre ville suisse, les températures n’ont autant grimpé au cours de ces 20 dernières années. Le nombre de jours de canicule est passé de 45 à 70 depuis 1984. Il y a six ans, le chef-lieu a lancé un projet pilote soutenu par la Confédération, « #AcclimataSion ». Le but est de mieux adapter l’#aménagement_urbain et les normes de construction au changement climatique, explique Lionel Tudisco, urbaniste de la ville. Le slogan qui accompagne le projet est le suivant : « Du vert et du bleu plutôt que du gris ». Dans l’espace public, on mise sur une végétalisation accrue. « Un arbre livre la même fraîcheur que cinq climatiseurs », souligne l’urbaniste. À l’ombre des arbres, on enregistre en journée jusqu’à sept degrés de moins qu’aux alentours. Le « bleu » est fourni à la ville par les cours d’eau, fontaines, lacs ou fossés humides : « Ils créent des microclimats et réduisent les écarts de température ». Ces mesures visent non seulement à réduire la chaleur en ville, mais aussi à atténuer le risque d’inondations. Car le changement climatique accroît aussi la fréquence des fortes précipitations. Les Sédunois l’ont constaté en août 2018, quand un orage violent a noyé les rues basses de la ville en quelques instants.

    La réalisation phare d’« AcclimataSion » est le réaménagement du cours Roger Bonvin, une promenade située sur la tranchée couverte de l’autoroute. Avant, cet espace public de 500 mètres de long était peu attrayant et, avec ses surfaces imperméabilisées, il était livré sans protection aux rayons du soleil. Aujourd’hui, 700 arbres dispensent de l’ombre et des promeneurs flânent entre les îlots végétalisés. Une plage de sable et un vaste espace où s’asseoir et se coucher créent une atmosphère de vacances. Des enfants barbotent dans des bassins.

    #Points_chauds sur les #cartes_climatiques

    Dans les grandes villes suisses aussi, le changement climatique préoccupe les autorités. La ville de #Zurich s’attend à ce que le nombre de jours de canicule passe de 20 à 44, et veut agir. « Notre but est d’éviter la #surchauffe sur tout le territoire urbain », explique Christine Bächtiger, cheffe du département municipal de la protection de l’environnement et de la santé. Concrètement, il s’agit de réduire autant que possible les surfaces goudronnées ou imperméabilisées d’une autre manière. Car celles-ci absorbent les rayons du soleil et réchauffent les alentours. La ville souhaite aussi décharger certains quartiers où la densité d’habitants est forte et où vivent de nombreux seniors, particulièrement sensibles à la chaleur. On envisage d’étoffer le réseau de chemins menant à des parcs ou à des quartiers moins chargés. Par rapport à d’autres villes, Zurich jouit d’une topographie favorable : trois quarts des zones habitées urbaines bénéficient d’un air frais qui arrive la nuit par les collines boisées entourant la ville. Pour préserver cette #climatisation_naturelle, il faut conserver des axes de #circulation_de_l’air lorsqu’on construit ou limiter la hauteur des immeubles.

    La ville de #Bâle a elle aussi repéré les îlots de chaleur, les espaces verts rafraîchissants et les flux d’air sur une #carte_climatique. Des urbanistes et des architectes ont utilisé ces données pour construire le quartier d’#Erlenmatt, par exemple. Là, les bâtiments ont été orientés de manière à ne pas couper l’arrivée d’air frais de la vallée de Wiesental. De grands #espaces_ouverts et des rues avec des zones de verdure façonnent également l’image de ce nouveau quartier urbain construit selon des principes durables.

    La ville de #Genève, quant à elle, mise sur une végétalisation accrue. Les autorités ont arrêté l’été dernier un plan stratégique faisant de la végétalisation un instrument à part entière du Plan directeur communal. Dans le cadre du programme « #urbanature » déjà, les jardiniers municipaux avaient planté près de 1200 arbres et 1,7 million de plantes dans l’#espace_public. La municipalité juge par ailleurs qu’un changement de paradigme est nécessaire du côté de la #mobilité, avec une diminution du #trafic_individuel_motorisé. Ainsi, des cours intérieures aujourd’hui utilisées comme places de parc pourraient être végétalisées. Les arbres apportent de la fraîcheur en ville, et ils absorbent les particules fines qui se trouvent dans l’air.

    La ville de #Berne compte elle aussi agir à différents niveaux. Ainsi, les #revêtements ne seront plus imperméabilisés que si cela s’avère indispensable pour le trafic ou l’accès des personnes handicapées. Tandis qu’un revêtement en #asphalte sèche immédiatement après la pluie, l’eau s’infiltre dans les surfaces en #gravier et peut s’évaporer plus tard. « Nous devons repenser tout le #circuit_de_l’eau », déclare Christoph Schärer, directeur de Stadtgrün Bern. L’#eau ne doit plus être guidée au plus vite vers les #canalisations, mais rester sur place pour contribuer au #refroidissement_de_l’air par l’#évaporation ou pour assurer l’#irrigation. « Chaque mètre carré non imperméabilisé est un mètre carré gagné. » À Berne, les nombreuses #fontaines et #cours_d’eau participent aussi au refroidissement de l’atmosphère, comme le Stadtbach qui coule à ciel ouvert dans la vieille ville.

    En ce qui concerne la végétalisation, Berne adopte de plus en plus de variétés d’arbres « exotiques » adaptés au changement climatique. Certains arbres indigènes comme le tilleul à grandes feuilles ou l’érable sycomore supportent mal la chaleur et la sécheresse. Alors on plante par exemple des #chênes_chevelus. Ce feuillu originaire du sud de l’Europe supporte le chaud, mais aussi les hivers froids et les gelées printanières tardives qui ont été fréquentes ces dernières années. Christoph Schärer ne parlerait donc pas d’une « #méditerranéisation », du moins pas en ce qui concerne les arbres.

    • Acclimatasion

      Le climat se réchauffe et les événements extrêmes se multiplient. Avec ACCLIMATASION la Ville de Sion s’est engagée pour la réalisation d’aménagements urbains qui donnent la priorité à la végétation et au cycle de l’eau. Objectif ? Diminuer la chaleur, favoriser la biodiversité et limiter les risques d’inondation.

      La Confédération réagit face au changement climatique. De 2014 à 2016, elle a soutenu une trentaine de projets pilotes avec pour but d’identifier les meilleures pistes pour limiter les dommages et maintenir la qualité de vie des habitants.

      La Ville de Sion, en partenariat avec la Fondation pour le développement durable des régions de montagne, a été choisie pour mener à bien un projet lié à l’adaptation des villes au changement climatique, c’est ACCLIMATASION.

      Au terme du projet pilote une série de résultats concrets sont visibles, en particulier :

      Des aménagements exemplaires ont été réalisés par la Ville dans le cadre du projet pilote et se poursuivent aujourd’hui par la réalisation de nouveaux projets. Le réaménagement du Cours Roger Bonvin réalisé en 2016 est le projet phare d’ACCLIMATASION.
      Des projets privés ont été soutenus pour montrer des solutions concrètes et inciter les propriétaires à s’engager. Le guide de recommandations à l’attention des propriétaires privés capitalise les actions concrètes que tout un chacun peut entreprendre.
      Diverses actions ont été menées pour sensibiliser la population, échanger avec les professionnels et mobiliser les responsables politiques : événements de lancement et de capitalisation, expositions et concours grand public, interventions dans les écoles.
      Les outils d’aménagement du territoire évoluent progressivement, de même que les compétences des services communaux et des professionnels. En particulier, les principes d’un aménagement urbain adapté au changement climatique ont été consolidés dans des lignes directrices adoptées par l’exécutif de la Ville en 2017 et applicables à l’ensemble des espaces publics.

      Ce programme, lancé par le Conseiller administratif Guillaume Barazzone, repense les espaces publics bétonnés en les rendant plus conviviaux et en les végétalisant. À terme, il a comme ambition de favoriser la biodiversité en milieu urbain. Le programme urbanature rend Genève encore plus verte ; il est mis en place et réalisé par le Service des espaces verts (SEVE).

      Le programme
      Corps de texte

      Il comprend trois niveaux d’action : des réalisations temporaires et saisonnières (fin mai à fin octobre), des aménagements durables, ainsi que l’élaboration d’un plan stratégique de végétalisation.

      Chaque année, des réalisations temporaires permettent d’amener de la végétation rapidement dans différents secteurs de la Ville. Depuis 2015, des projets durables de végétalisation sont réalisés afin d’étendre le maillage vert encore essentiellement constitué par les parcs. Le plan stratégique de végétalisation de la Ville sert à décrire les différentes actions concrètes à mener à long terme pour rendre Genève encore plus verte.

  • “Cambiamento climatico e rischio. Proposte per una didattica della geografia” (nuovo volume della collana “Tratti geografici”)

    Il volume nasce con l’obiettivo di dare un contributo e aprire a nuove riflessioni nell’insegnamento geografico, sia attraverso elementi teorici sia attraverso la proposta di attività pratiche, che mirano ad affrontare in modo sistematico i temi del rischio e del cambiamento climatico. Partendo dall’esperienza fatta in occasione del 61° Congresso Nazionale AIIG (Termoli, 4-8 ottobre 2018) e da successivi momenti formativi promossi da alcune AIIG locali, è stato possibile testare e ragionare sul ruolo che la geografia può avere nella diffusione di queste tematiche, e sulla responsabilità che le deriva in quanto disciplina di sintesi. I temi in oggetto, infatti, sono spesso ai margini dell’insegnamento e dell’attenzione geografica, nonostante rivestano un ruolo cardine nella comprensione dei territori e nell’elaborazione/promozione delle politiche economiche, sociali e ambientali. L’idea di focalizzare l’attenzione di questo volume su un argomento specifico nasce dalla consapevolezza che ora più che mai appare necessario riconoscere la geografia del rischio come ambito di ricerca e riflessione portante della geografia italiana. Al fine di mettere a disposizione uno strumento il più esauriente possibile da proporre alle scuole e agli educatori, è stato utile e necessario guardare non solo a geografi ma più in generale ad operatori del territorio che quotidianamente si rapportano con queste tematiche. Le esperienze e le attività proposte, pertanto, provengono da attori diversi (protezione civile, ong, università) con l’obiettivo di fornire un primo strumento di lavoro, che possa avere dei risvolti pratici oltre che di stimolo. In particolare, è stato dato spazio a metodologie di lavoro differenti che guardassero a diverse tipologie di rischio (cambiamenti climatici, terremoti, multi-hazard, ecc.) capaci di offrire alcuni primi spunti di riflessione nonché esempi replicabili e ulteriormente sviluppabili da insegnanti di diverso ordine e grado.

  • « Dès que les êtres humains pénètrent dans un #écosystème, des #virus se propagent »

    Le Bruno Manser Fonds (BMF) s’est entretenu avec #Kinari_Webb, médecin et fondatrice de Health in Harmony, sur la manière dont la destruction de l’environnement affecte notre santé et permet la propagation de maladies telles que le #COVID-19.

    Kinari Webb, 48 ans, est médecin et fondatrice de « Health in Harmony », un projet intégrant service de #santé et #protection_de_l’environnement dans le #Kalimantan, la partie indonésienne de #Bornéo. Elle a achevé ses études de bachelor en biologie en 1993, pour ensuite partir à Bornéo y étudier les orangs-outans. Elle y a vu comment de nombreuses personnes ne pouvaient financer leurs soins de santé autrement qu’en défrichant. Elle a donc décidé d’étudier la médecine. Après ses études, elle s’est à nouveau rendue à Bornéo, où elle a créé « Health in Harmony » en 2005, dans les environs du parc national #Gunung_Palung. Elle vit à proximité de San Francisco ainsi qu’en Indonésie.

    De quelle manière l’environnement et la santé sont-ils liés ?

    Kinari Webb : La question est mal posée à mes yeux. En effet, elle présuppose que l’être humain n’est pas un animal et qu’il y a une scission entre l’homme et la nature. Mais c’est impossible : nous respirons l’air, nous buvons l’eau, nous nous alimentons. La croyance selon laquelle notre esprit serait séparé nous vient du Siècle des lumières et s’avère simplement fausse. Cette pandémie nous montre à l’évidence que nous sommes indissociables de la #nature, comme d’ailleurs du changement climatique : sans températures raisonnables, en l’absence de suffisamment d’oxygène, sans eau propre, sans nourriture saine, nous ne pouvons pas être en bonne santé, nous ne pouvons pas survivre.

    Comment les #défrichages impactent-ils la santé des populations rurales à Bornéo ?

    Là où nous travaillons, tout-un-chacun sait que son bien-être futur dépendra de la présence de la #forêt tropicale. Ils comprennent que la forêt produit de l’eau, que celle-ci irrigue les champs de riz et que les champs de riz à leur tour les nourriront. Ils savent que, sans eau propre, les maladies se propagent. Ils savent aussi que les défrichages détruisent l’équilibre de l’écosystème et occasionnent davantage de #maladies comme le paludisme.

    Quelles sont les répercussions de la déforestation et de la destruction de l’environnement sur la santé des êtres humains à l’échelle mondiale ?

    La plupart des gens savent que notre consommation de combustibles fossiles est à l’origine du changement climatique. Peu de gens savent par contre que la déforestation à l’échelle mondiale est à l’origine d’autant d’émissions de CO2 que l’intégralité du secteur des transports dans le monde. Lorsque nous défrichons les forêts ou les brûlons, nous rejetons d’énormes quantités de carbone dans l’atmosphère. Les sols tourbeux à Bornéo jouent ici un rôle incroyablement important. On peut se les représenter comme des stades précoces des champs pétrolifères, dans lesquels des feuilles et des branchages se sont accumulés durant des millions d’années et qui ne peuvent pas se décomposer car ils sont recouverts d’eau. Si l’on défriche ou incendie les forêts sur #tourbières, le carbone stocké s’en trouve libéré. Les arbres accumulent de plus en plus de carbone tant qu’ils sont sur pied, absorbant ainsi un tiers du CO2 mondial. Je vais être explicite : si nous perdons nos #forêts_tropicales mondiales, c’est la fin de l’espèce humaine. Compte tenu de la chaleur, la planète serait invivable pour nous êtres humains de même que pour la majeure partie des autres êtres vivants.

    Quel est le lien avec le COVID-19 ? Et qu’est-ce qu’une zoonose ?

    Une #zoonose est une maladie transmise de la faune sauvage à l’être humain. Dans les écosystèmes intacts, on rencontre rarement des zoonoses. Mais dès que les hommes pénètrent dans un écosystème, le déstabilisent et consomment des #animaux_sauvages, des virus de propagent. Les marchés proposant des #animaux vivants constituent ici la plus grande menace, car c’est ici qu’apparaissent la plupart des zoonoses : on y trouve des animaux de différents coins du monde, gardés dans des conditions de stress élevé. Leur #système_immunitaire s’effondre, les virus se multiplient et se propagent entre les animaux, passant la barrière des espèces à l’être humain. Cela n’a pas été le cas que pour le COVID-19, mais aussi dans les derniers SRAS, MERS, Ebola et même le VIH. Ne pas respecter les écosystèmes nous fait courir de grands dangers. Ce n’est qu’une question de temps jusqu’à ce qu’apparaisse la prochaine pandémie.

    La consommation de #viande_sauvage est donc remise en question. Comment vois-tu cela dans les villages ruraux de Bornéo, dans lesquels la viande de chasse constitue un aliment de base ?

    La consommation de la viande de chasse dans les zones rurales comporte certains risques. Pourtant, tant que ces animaux proviennent d’écosystèmes intacts, le risque est réduit. Il est probable que le COVID-19 est passé des #chauves-souris aux #pangolins avant de parvenir à l’être humain. Les pangolins sont notamment capturés en Malaisie, transportés vers la Chine pour y être vendus sur les marchés. C’est donc tout autre chose que lorsque de la viande de chasse est consommée d’un environnement intact. Ces villages à Bornéo consomment cette viande depuis longtemps et sont déjà entrés en contact avec des virus locaux. Ils possèdent déjà un #système_immunitaire qui sait réagir à ces virus afin de ne pas dériver en pandémie.

    Qu’en est-il des #élevages_intensifs ?

    Les élevages intensifs comportent aussi des risques, mais moins en ce qui concerne un virus totalement nouveau. Les forêts tropicales humides de ce monde ne recouvrent que 2 % de la superficie de la Terre, mais elles hébergent 50 % de toutes les espèces. C’est une richesse énorme aussi bien qu’une source de nouveaux virus dès le moment qu’on les transporte à l’autre bout du monde. Les élevages intensifs ne sont toutefois pas sans comporter de dangers, car un virus de la grippe peut s’y propager sans encombre, vu que les animaux y sont stressés et que leur système immunitaire s’en trouve affaibli. À l’avenir, en rétrospective nous nous demanderons comment nous avons pu faire une telle chose.

    Avec « Health in Harmony », vous travaillez à l’interface des services de santé et de la protection de l’environnement. Quelle idée se cache derrière votre projet ?

    La première fois que je me suis rendue à Bornéo, afin d’y étudier les orangs-outans, je suis tombée amoureuse de la forêt tropicale et des gens. Mais j’ai été sidérée de voir comment les gens, qui aimaient leur forêt, étaient contraints de la détruire pour payer leurs soins de santé. Un homme y avait abattu 60 arbres pour payer une césarienne. J’ai donc décidé d’étudier la médecine et suis ensuite retournée en #Indonésie. J’ai demandé aux gens où ils voyaient la solution. Ils m’ont expliqué qu’ils avaient besoin d’un accès à des soins médicaux à prix abordable et de connaissances en agriculture biologique, pour protéger la forêt tropicale. Nous avons mis leurs idées en œuvre et permis aux gens de payer leurs soins de santé au moyen de plants d’arbres et de travail. Après 10 ans d’activité, on a constaté un recul de 90 % des ménages réalisant leur revenu avec les défrichages. Nous avons pu arrêter la perte supplémentaire de forêt, sa surface ayant même gagné 21 000 hectares. La mortalité infantile a reculé de 67 % et la situation financière des populations s’est même améliorée.

    Compte tenu de ton expérience, à quoi ressemblerait une solution mondiale ?

    Nous avons démontré que les hommes et les écosystèmes peuvent prospérer ensemble. Nous devons comprendre que le bien-être des gens en Malaisie, qui capturent un pangolin parce qu’ils n’ont aucun autre revenu, et celui des gens en Chine, où le pangolin est envoyé, de même que celui de tous les êtres humain sur la planète, sont interdépendants. Nous avons tous besoin d’écosystèmes sains. Beaucoup voient une concurrence entre la nature et l’homme : « Comment pouvons-nous protéger la nature si nous devons manger ? » Mais cela ne fonctionne pas ainsi, c’est juste le contraire. Demandez aux gens où se trouvent les solutions et collaborez ! Les écosystèmes et les êtres humains en ressortent gagnants. Imagine que chacune et chacun bénéficie de soins de santé universels et doit y apporter sa contribution. Imagine que ta contribution individuelle dépend de combien tu prends l’avion et de la contrainte que tu as sur l’environnement.
