Climate change impacting fish reproduction in the Sundarbans: Study

Some of West Bengal’s most-loved fish may go off the menu, thanks to climate change in the Sundarbans.
A team of researchers that is mapping biological sensitivity of certain fish species to climate change says increasing salinity and temperature in the Sundarbans estuary is messing up their reproductive behaviour and may also likely alter their abundance, factors that could wipe them out one day, they warn.
Spanning 10,000 square km along the coast of India and #Bangladesh, the Sundarbans represent the largest expanse of contiguous mangrove forests in the world. This globally significant ecosystem is situated in the Bay of Bengal, within the delta of the Ganges, Brahmaputra, and Meghna rivers.
The Indian Sundarbans archipelago acts as the “nursery” for nearly 90 percent of the aquatic species of eastern coast of India. It is the top producer of fish and prawn, with both districts (South and North- 24 Parganas) combined producing roughly 31 percent of the total inland fish/prawn production of West Bengal, a state iconic for its fish-eating habits. Sundarbans also satiates 15 to 20 percent of the state capital Kolkata’s fish requirement.

More than half of south Asia’s groundwater too contaminated to use – study | The Guardian

Sixty per cent of the groundwater in a river basin supporting more than 750 million people in Pakistan, India, Nepal and Bangladesh is not drinkable or usable for irrigation, researchers have said.
The biggest threat to groundwater in the Indo-Gangetic Basin, named after the Indus and Ganges rivers, is not depletion but contamination, they reported in the journal Nature Geoscience.

A new power plant could devastate the world’s largest mangrove forest - The Washington Post

The planet’s largest mangrove forest could be facing serious trouble in the form of two new coal-fired power plants, environmentalists say — and they’re urging the United Nations to draw greater attention to the issue.
A handful of environmental groups, including Friends of the Earth, the Sierra Club and 350.org, have cumulatively collected 50,000 signatures on a petition just submitted to the United Nations Educational, Scientific and Cultural Organization (UNESCO) asking that the Sundarbans — a region of #Bangladesh including a designated World Heritage Site — be placed on the official List of World Heritage in Danger. Meanwhile, activists continue to lobby against the construction of the power plants.
...
The most recently proposed project is the Orion power plant, a 630-megawatt plant being planned by the Orion Group. But the project receiving the most attention is the proposed Rampal power plant, which involves a partnership between India’s state-owned National Thermal Power Corp. and the Bangladesh Power Development Board. The joint venture, which was established in 2012, is known as the Bangladesh-India Friendship Power Co. Ltd., or BIFPCL. The plan for the Rampal power plant is an installed capacity of 1,320 megawatts.

The Sundarbans mangrove forest, one of the largest such forests in the world (140,000 ha), lies on the delta of the Ganges, Brahmaputra and Meghna rivers on the Bay of Bengal. It is adjacent to the border of India’s Sundarbans World Heritage site inscribed in 1987. The site is intersected by a complex network of tidal waterways, mudflats and small islands of salt-tolerant mangrove forests, and presents an excellent example of ongoing ecological processes. The area is known for its wide range of fauna, including 260 bird species, the Bengal tiger and other threatened species such as the estuarine crocodile and the Indian python.

#Google s’offre une flotte de satellites

Pour 500 millions de dollars, Google s’offre Skybox Imaging, une société américaine spécialisée dans la fabrication de petits satellites d’imagerie en haute définition. Grâce à la technologie développée par Skybox Imaging, Google mettra à jour ses cartes de la Terre et étendra son service d’accès à Internet.
Dans les exemples : vue satellite d’Alep pour y suivre une « crise humanitaire »…

  Inside a Startup’s Plan to Turn a Swarm of DIY Satellites Into an All-Seeing Eye (18-06-2013)
  ▻http://www.wired.com/2013/06/startup-skybox
  Here is the soaring vision that Skybox’s founders have sold the Valley: that kids from Stanford, using inexpensive consumer hardware, can ring Earth with constellations of imaging satellites that are dramatically cheaper to build and maintain than the models currently aloft. By blanketing the exosphere with its cameras, Skybox will quickly shake up the stodgy business (estimated to grow to $4 billion a year by 2018) of commercial space imaging. Even with six small satellites orbiting Earth, Skybox could provide practically real-time images of the same spot twice a day at a fraction of the current cost.
  But over the long term, the company’s real payoff won’t be in the images Skybox sells. Instead, it will derive from the massive trove of unsold images that flow through its system every day—images that, when analyzed by computer vision or by low-paid humans, can be transmogrified into extremely useful, desirable, and valuable data. What kinds of data? One sunny afternoon on the company’s roof, I drank beers with the Skybox employees as they kicked around the following hypotheticals:
  — The number of cars in the parking lot of every Walmart in America.
  — The number of fuel tankers on the roads of the three fastest-growing economic zones in China.
  — The size of the slag heaps outside the largest gold mines in southern Africa.
  — The rate at which the wattage along key stretches of the Ganges River is growing brighter.
  Such bits of information are hardly trivial. They are digital gold dust, containing clues about the economic health of countries, industries, and individual businesses. (One company insider confided to me that they have already brainstormed entirely practical ways to estimate major economic indicators for any country, entirely based on satellite data.) The same process will yield even more direct insight into the revenues of a retail chain or a mining company or an electronics company, once you determine which of the trucks leaving their factories are shipping out goods or key components.
  Plenty of people would want real-time access to that data—investors, environmentalists, activists, journalists—and no one currently has it, with the exception of certain nodes of the US government. Given that, the notion that Skybox could become a Google-scale business—or, as one guy on the roof that afternoon suggested to me, an insanely profitable hedge fund—is not at all far-fetched. All they need to do is put enough satellites into orbit, then get the image streams back to Earth and analyze them. Which is exactly what Skybox is planning to do.

Just after his sophomore year at Yale in 2002, Billy Parish stood before a rapidly retreating glacier in India that feeds the Ganges River, convinced that he had come face to face with climate change and that he had to do something about it.
