Rural adolescents commit suicide at roughly twice the rate of their urban peers, according to a study published in the May issue of the journal JAMA Pediatrics. Although imbalances between city and country have long persisted, “we weren’t expecting that the disparities would be increasing over time,” said the study’s lead author, Cynthia Fontanella, a psychologist at Ohio State University.

“The rates are higher, and the gap is getting wider.” — the New York Times

This is important for Africa, where despite high urbanisation rates the development focus has been primarily rural. Consider Ghana. The country’s urban population has grown from four million in 1984 to more than 14 million today. Fifty one percent of Ghanaians now live in cities.

How great are the benefits of density? Economists studying cities routinely find that after controlling for other variables, workers in denser places earn higher wages and are more productive. Some studies suggest that doubling density raises productivity by around 6 percent while others peg the impact at up to 28 percent. — nytimes.com

Agricultural researchers believe that building indoor farms in the middle of cities could help solve the world's hunger problem. Experts say that vertical farming could feed up to 10 billion people and make agriculture independent of the weather and the need for land. There's only one snag: The urban farms need huge amounts of energy. — spiegel.de

For at least a century, governments have tried to urbanise their nations. Communist states sought to drag people out of what Marx and Engels called their "rural idiocy". Capitalist governments – Mahatir Mohammed's administration in Malaysia is a good example – tried to persuade and bully indigenous people into leaving the land (which then became available for exploitation) and move to the cities to join the consumer economy. Urbanisation was equated with progress and modernity. — George Monbiot, guardian.co.uk
