"The Sahel’s ability to produce food is not keeping pace with its growing population, and global warming will only exacerbate the imbalance, according to a new study. Among the 22 countries making up the arid region in northern Africa, the population grew to 471 million in 2010 from 367 million in 2000, a jump of nearly 30%. As the population grew rapidly, the production of crops remained essentially unchanged. Using satellite images to calculate annual crop production in the conflict-ridden Sahel belt, south of the Sahara desert, the researchers then compared output with population growth and food and fuel consumption."
UNHCR has been attempting to count the world's refugees since it was created. If you want to find out which years resulted in the worst displacement, which were the biggest countries of origin and which were the biggest countries of asylum, use the interactive map.
"Henry Monterroso is a foreigner in his own country. Raised in California from the age of 5, he was deported to Mexico in 2011 and found himself in a land he barely knew. But the 34-year-old now supervises five employees amid rows of small cubicles who spend eight hours a day dialing numbers across the United States. He is among thousands of deported Mexicans who are finding refuge in call centers in Tijuana and other border cities. In perfect English — some hardly speak Spanish — they converse with American consumers who buy gadgets, have questions about warrantees or complain about overdue deliveries."
"Why are all the gas stations, cafes and restaurants in one crowded spot? As two competitive cousins vie for ice-cream-selling domination on one small beach, discover how game theory and the Nash Equilibrium inform these retail hotspots."
INDIA’S general election will take place before May. The front-runner to be the next prime minister is Narendra Modi of the Bharatiya Janata Party, currently chief minister of Gujarat. A former tea-seller, he has previously attacked leaders of the ruling Congress party as elitist, corrupt and out of touch. Now he is emphasising his humble caste origins. In a speech in January he said 'high caste' Congress leaders were scared of taking on a rival from 'a backward caste'. If Mr Modi does win, he would be the first prime minister drawn from the 'other backward classes', or OBC, group. He is not the only politician to see electoral advantage in bringing up the subject: caste still matters enormously to most Indians."
"One-third of the seafood Americans catch is sold abroad, but most of the seafood we eat here is imported and often of lower quality. Why? Author Paul Greenberg says it has to do with American tastes."
"In 2001 the world began talking about the Bric countries - Brazil, Russia, India and China - as potential powerhouses of the world economy. The term was coined by economist Jim O'Neill, who has now identified the 'MINT' countries - Mexico, Indonesia, Nigeria and Turkey - as emerging economic giants. Here he explains why."

Scientists have issued a new warning to the world’s coastal megacities that the threat from subsiding land is a more immediate problem than rising sea levels caused by global warming.
A new paper from the Deltares Research Institute in the Netherlands published in April identified regions of the globe where the ground level is falling 10 times faster than water levels are rising - with human activity often to blame.
In Jakarta, Indonesia’s largest city, the population has grown from around half a million in the 1930s to just under 10 million today, with heavily populated areas dropping by as much as six and a half feet as groundwater is pumped up from the Earth to drink.
The same practice led to Tokyo’s ground level falling by two meters before new restrictions were introduced, and in Venice, this sort of extraction has only compounded the effects of natural subsidence caused by long-term geological processes.
