A northern wind had been blowing since early morning, lifting a veil of dust that had blocked the sun and turned the sky the color of ash. Abu Zayed was sitting on the porch of his unfinished concrete home, watching the storm build. He loved sandstorms. They reminded him of Dubai, where he had lived before the war. He admired the people there for turning a desert into a paradise. They had vision, he told his followers.

October 31, 2011, was notable not only for the annual ritual of candy and costumes, but also for its designation by the United Nations as the date when global population reached seven billion. Although just an estimate – demographers are not able to count individuals in real time on such a large scale – the event was an important opportunity to present population trends to the media and public dialogue. Several babies born that day were named the “seven billionth;” in Russia, where various incentives have been implemented to try to boost an ultra-low fertility rate, Vladimir Putin visited a maternity ward to greet one of them.

As President Obama readies a new road map for addressing climate change in the United States, experts warn that poorly designed and implemented initiatives, especially in already-fragile parts of the world, could unintentionally provoke conflicts, rather than diffuse them.

“Most of the world’s poor are farmers; they share the same profession and the same challenges,” said One Acre Fund’s Stephanie Hanson at a recent Wilson Center event on small-scale farming, climate change, food security, and migration.

Few terms in demography can cause more confusion than “urbanization.” News stories reporting projections of world urbanization are nearly always accompanied by photographs of places such as London or Shanghai, and it does seem rather natural to think of urbanization in those terms.

Mexico’s 2012 elections were important for a host of reasons: the PRI party returned to power after 12 years of rule by the more conservative PAN; there was the first female presidential candidate from a major political party; and turn-out was historically high. They also proved that Mexico’s young people are not as apathetic as some may have thought, with the emergence of the #YoSoy132 student movement demanding fair press coverage.
