“Unless something changes in a major way, Nigeria will pass the United States as the third most populous country by mid-century and rival China with its number of people by the end of the century,” said Ken Weiss in his introduction to a recent webinar hosted by Resource Media. But what does population growth have to do with the environment?

“In the post-Cold War period, the challenges of energy, environment, climate change, and water have become very much a part of our fundamental transatlantic relationship,” said CNA General Counsel Sherri Goodman, launching a new report on U.S.-EU security at the Wilson Center. [Video Below]

I remember the first moment when my interest in national security came crashing into ecological reality. I was on a U.S. government trip to Central Asia to inspect uranium mines in the newly-independent states of the former Soviet Union. The Cold War security imperative to achieve nuclear superiority had done a number on the environment there: Uranium was leached from the ground with sulfuric acid, transformed into a uranium oxide powder called yellowcake, and shipped off to be enriched for nuclear reactor fuel or weapons. The generals in Moscow who issued these orders did not see the collateral damage that their idea of security wreaked on the environment in Central Asia. In their attempt to out-weaponize the United States, they laid waste to the groundwater, agriculture, and public health of their own citizens.

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.

“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. They are tasked with growing enough food to support their families with only tenuous access to land and natural resources, the most basic of tools, and increasingly unpredictable weather patterns to deal with. [Video Below]

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.

Despite the appearance of a new, “greener” economy, extractive industries – mining, oil, and natural gas – are now responsible for “moving more earth each year, just for mining and quarrying, than the global hydrological cycle,” writes the Transatlantic Academy’s Stacy VanDeveer in a recent paper, Still Digging: Extractive Industries, Resource Curses, and Transnational Governance in the Anthropocene. The costs of this activity are high and extend well beyond the wallet, he explains.
