What happened to history’s refugees?
People have been forced to leave their countries since the very notion of a country was created. We take a look at some of the largest human movements in history to find out why people left their homes, where they went and what became of them.

John Snow’s data journalism: the cholera map that changed the world | News | guardian.co.uk
▻http://www.guardian.co.uk/news/datablog/2013/mar/15/john-snow-cholera-map
How often does a map change the world? In 1854, one produced by Doctor John Snow, altered it forever.
In the world of the 1850s, #cholera was believed to be spread by miasma in the air, germs were not yet understood and the sudden and serious outbreak of cholera in London’s Soho was a mystery.
So Snow did something data journalists often do now: he mapped the cases. The map essentially represented each death as a bar, and you can see them in the smaller image above.
It became apparent that the cases were clustered around the pump in Broad (now Broadwick) street.
Tufte n’est pas d’accord avec cette présentation idéalisée du travail de Snow : ▻http://www.bortzmeyer.org/tufte-visual-explanations.html
Il y a tout un développement sur ce projet du milieu du XIXe siècle dans le rapport sur le développement humain 2006 (le thème était la flotte) du PNUD.

Pas de chance, Visual Explanations est le seul bouquin de Tufte que je n’ai pas dans ma bibliothèque…
Dans le livre qui l’a fait connaître, The Visual Display of Quantitative Information , quoiqu’un tout petit peu réticent, il reconnaissait tout de même quelque mérite au Dr John Snow. Mais c’était 15 ans avant, il n’avait pas encore pris le melon…
An early and most worthy use of a map to chart patterns of disease was the famous dot map of Dr. John Snow, who plotted the location of deaths from cholera in central London for September 1854. (…) Of course the link between the pump and the disease might have been revealed by computation and analysis without graphics, with some good luck and hard work. But, here at least, graphical analysis testifies about the data far more efficiently than calculation.
Data on gender that will make you smile, not groan | News | guardian.co.uk
▻http://www.guardian.co.uk/news/datablog/2013/mar/08/data-gender-global-voices
This week, our Open Gender Tracker team was astonished to find a news organisation with equal participation by women. At the international citizen media news site #Global_Voices, 764 women have written 51% of all posts, a trend they have held consistent for years, our data shows.
It’s reasonable to be downcast about the role of women in the news. In the UK, newspaper front pages rarely include women, and women write a minority of articles. Women are prominent at the Daily Mail, where they write most of the celebrity news, fewer news articles, and almost no sport. Even when publications do include women, they’re often at the mercy of their audiences. 20% of Telegraph opinion articles are written by women, but women’s opinion articles attract only 14% of the Telegraph’s shares and likes on social media.

Thousands of children ineligible for free school meals but live in ’hidden poverty’ | Society | The Guardian
▻http://www.guardian.co.uk/society/2013/mar/07/children-ineligible-free-school-meals-poverty
Tens of thousands of children living below the poverty line in some of the wealthiest parts of England’s home counties may be unable to afford a proper lunch but fail to qualify for free school meals, according to a study by the Children’s Society.
The charity urged the government to extend free school meals eligibility to more low-earning families, who may be in full-time jobs but struggle to get by.
In 57 of England’s 533 parliamentary constituencies, more than 60% of children living in poverty were either ineligible or failing to claim free school meals, according to the Children’s Society data, with these concentrated in the south-east, London and east of England. There were just 22 constituencies, all of them in the north of England and the Midlands, where fewer than 10% of children missed out.
An estimated 900 children living in poverty in David Cameron’s constituency in Witney, West Oxfordshire, miss out on a free school meal (47%). The figure is 1,400 (57%) in the education secretary Michael Gove’s Surrey Heath constituency; and 3,200 (58%) in Iain Duncan Smith’s Chingford and Woodford Green seat.
Labour leader Ed Miliband’s Doncaster North seat has 1,400 children missing out (33%). In the shadow chancellor Ed Balls’ Morley and Outwood constituency, 200 children (11%) were affected, while according to the figures data deputy prime minister Nick Clegg’s Sheffield Hallam constituency appears to have no children in poverty missing out on a free school meal.
The Children’s Society estimates that of 1.2 million children living in poverty in England that miss out on a free school meal, 700,000 do so because they are ineligible. The rest are believed not to take up the offer because they suffer stigma, teasing or embarrassment or because their parents are unaware of it.
Where are kids in poverty missing out on free school meals?
▻http://www.guardian.co.uk/news/datablog/interactive/2013/mar/07/free-school-meals-children-map
The numbers of children taking free school meals (FSM) is commonly referred to as a poverty indicator. But what if thousands of children in poverty are missing out on FSM? Latest research from the Children’s Society shows that is what is happening across England. To find the figure, they subtracted the number of children known to be registered for free school meals from an estimate of the number of children in poverty (after housing costs) in each constituency. Families are normally entitled to get free school meals if they have a lone parent working on a low income for less than 16 hours per week, or fewer than 24 hours a week for a couple. If their parents work more than this, children won’t get a free school meal, no matter how little their parents earn. Click on a constituency to explore the data

The EU used to collect data on slaughtering of horses but stopped in 2008 when a voluntary agreement was made between Member States to provide this information. Since then, no country has made its data available.
In recent years, statistics have however been published on imports and exports of horsemeat. Though the data is incomplete, it does provide an indication of the UK and Ireland’s place in EU trade of horsemeat.

OK, sérieux ? Il y a 15 tonnes d’eau dans 1 kg de viande ?
Ah oui, c’est parce qu’il y a 3000 tonnes d’eau dans le grain qu’a mangé la vache en 3 ans ?
Et donc utilisé (used) c’est pareil que gâché (wasted) ?
Je n’y connais rien du tout, mais je lis (WP) « l’évapotranspiration peut atteindre 4 à 6 mm d’eau par mètre carré cultivé », ce qui fait (fourchette basse) quand même 40 tonnes d’eau par hectare et par jour en plein été. Vue la masse finale du grain de blé, l’immense majorité de l’eau qu’il a vu passer est repartie dans les nuages.
Toute l’eau, toujours, est absorbée, pas une goutte, jamais, n’est récupérée. Je veux bien qu’on fasse des bilans, mais pas n’importe quoi…
Bon, après le coup de gueule sur l’infographie, revenons à la raison.
Oui, sur un bassin versant la ressource en eau est limitée. Une partie est renouvelable, une autre ne l’est pas (pompage des nappes profondes). Et notre consommation en eau, elle ne semble pas limitée.
Alors, oui, il est vital de réfléchir à ce à quoi on utilise l’eau. Et, certainement, la viande est une forme d’alimentation très consommatrice de ressources et d’un rendement médiocre. D’ailleurs, ça a toujours été une nourriture de riches.
Et pour finir, en cherchant des infos sur la consommation de viande, je tombe :

Bien vu @liotier. D’ailleurs j’étais tombée sur un reportage sur une vendeuse d’insectes frits dans les quartiers chaud de Bangkok où c’est perçu comme une nourriture peu chère et à la limite de la friandise. Tu voyais que c’était un gros business, avec des zones d’appro dans les jungles, des élevages qui relançaient un peu l’économie de certains villages, avec des grossistes, et tout un marché de l’insecte : des bien frais, des bas de gamme, des qualités supérieures. La marchandes bossait dur pour ramasser les meilleurs insectes chez le meilleur grossiste et elle avait sélectionné l’huile qui les rendait brillants et appétissants. Bref, c’est comme tout, il faut un art culinaire qui se développe autour, sinon, c’est aussi peu inspirant qu’un bol de tripes tiédasses et mal lavées.

In 2008, Chris Anderson, then editor of Wired, wrote a provocative piece titled The End of Theory. Anderson was referring to the ways that computers, algorithms, and big data can potentially generate more insightful, useful, accurate, or true results than specialists or
domain experts who traditionally craft carefully targeted hypotheses
and research strategies.

Scottish fish farmers use record amounts of parasite pesticides | Environment | The Guardian
►http://www.guardian.co.uk/environment/2012/sep/10/scottish-fish-farmers-parasite-pesticide
Scottish fish farmers have been forced to use record amounts of highly toxic pesticides to combat underwater parasites that prey on salmon, raising fears of significant damage to the marine environment.
Data released by the Scottish Environment Protection Agency (Sepa) shows a 110% increase in the use of chemicals to treat sea lice in the past four years, mainly because the parasite is becoming resistant to treatment. During that same period, however, salmon production has increased only by 22%, to 158,000 tonnes.
The agency said it was not carrying out any studies into the impact of the chemicals on the marine environment, but added that there was no evidence of any cumulative damage from increasing use of pesticides.
mouais... et les impacts sur la santé des consommateurs ?
Chemicals to control salmon parasites

The data, requested by the campaigner Don Staniford who runs the website Fishyleaks, shows that overall use of pesticides by the salmon farming industry has increased each year, from 188kg in 2008 to 395kg last year – an increase of some 110%.
In that same period, salmon production increased more modestly, by some 22% to a forecast total of 157,000 tonnes last year.

The man behind the Norway bombings and shootings wrote a link-filled manifesto. To show the vast spread of websites he cites, and how they linked to each other, we turned to French visualisers Linkfluence.
This map shows those relationships between sites. To appear on it does not make anyone responsible for Breivik’s actions. Rather it shows how a conspiracist mind can twist perfectly normal stories into a threatening and dangerous pattern.
For each site on the map, you click the dot to go there directly - and it then illuminates all links to other sites. The sites have been divided by category - click on the icon with three circles in the right-hand corner to see the sites grouped.
