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.

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.

Midwives play a critical but unheralded role in maternal health. Their skills are sometimes marginalized in otherwise well-meaning discussions about professionalizing care, or even worse, they are subject to abuse, as was discussed at the Wilson Center earlier this month. So when I found the room overflowing at a Women Deliver panel yesterday on the disempowerment of midwives and how much it undermines global efforts to increase access to care, I took that as a good sign that midwives will not be overlooked much longer.

Water is the foundation of human society and will become even more critical as population growth, development, and climate change put pressure on already-shrinking water resources in the years ahead. But will this scarcity fuel conflict between countries with shared waters, as some have predicted, or will it create more impetus for cooperation?

The theme of this year’s International Women’s Day is “a promise is a promise: time for action to end violence against women.” The theme reflects that although there are a number of treaties and conventions that on paper promise to protect women’s rights, equality, and security, in reality, those promises to protect human rights have been broken time and again.

Rich, untapped deposits of gold, iron, copper, lithium, and rare earth minerals have been known in Afghanistan for decades, but recently, extensive reports from the U.S. Department of Defense and U.S. Geological Survey have shed new light on their potential value.

“We are at a critical juncture in human history, which could lead to widely contrasting futures,” writes the chairman of the National Intelligence Council (NIC) Christopher Kojm in the council’s latest forward-looking quadrennial report, Global Trends 2030: Alternative Worlds, released yesterday.

This year, principal author Mathew Burrows and his colleagues focus on a series of plausible global scenarios for the next 20 years and the trends or disruptions that may influence which play out. Among the most important factors in these projections are demography and the environment.

“When I embarked on this series, I approached it as an environmental reporter: What does a growing number of us and growing consumption mean for our planet?” said Los Angeles Times reporter Ken Weiss at the Wilson Center on October 9. Weiss, along with photographer Rick Loomis, recently completed a five-part series and multimedia presentation on global population that was the culmination of a year of research and travel through more than six countries. [Video Below]
