In 2009, economist Jeffrey Sachs, alongside more than 20 eminent scholars from different fields, highlighted the importance of biodiversity for human well-being in a policy commentary published in Science. They noted the Millennium Development Goals (MDGs) included a target to achieve, by 2010, a significant reduction in the rate of species loss, and they also noted that it was one of the MDG targets that was most off-track. “Our lack of progress toward the 2010 target,” they said, “could undermine achievement of the MDGs and poverty reduction in the long term.” The 2010 target was missed, and today species are moving toward extinction at an ever faster pace. Last week’s announcement confirming the extinction of Africa’s western black rhino is the latest sad example of this trend.

“We knew that we had a lot of reports, we knew that we had a lot of policy papers, but what we wanted to tell was a good story,” said ECSP’s Sean Peoples speaking recently at Duke University about the short documentary, Healthy People, Healthy Environment: Integrated Development in Tanzania.

These factors combine with existing development challenges to create security threats that African governments and the United States should be concerned with, says ECSP Director Roger-Mark De Souza in a presentation for the Africa Center for Strategic Studies’ introductory course on demography and the environment at the National Defense University.

China is one of the world’s 12 “mega-biodiversity” countries, but its incredible natural landscapes, from Sichuan’s sparkling, turquoise-colored lakes to Guilin’s dramatic karst topography, are bearing the cost of rapid economic development, writes British environmental photojournalist and videographer Sean Gallagher in a new multimedia e-book.

Haze may be the new weapon of mass destruction. Not in the narrow sense of an incoming ballistic missile, of course, but for millions in Southeast Asia, this summer’s sooty haze poses a threat more dire than a nuclear-tipped missile.

Ecuador, the OPEC member with the smallest amount of proven oil reserves, has gained outsized attention in the debate over the future of oil extraction in recent days and may well play a decisive role in the outcome of the global tension between economic development and environmental conservation.
