Earlier this month, the United Nations released a final report on the Millennium Development Goals (MDGs), the framework that has guided global development efforts for the last 15 years. The document examines each of the eight MDGs and finds that “despite many successes, the poorest and most vulnerable people are being left behind.” As one of the first global poverty reduction movements nears its end, the report calls for better data collection practices to create a post-2015 development agenda that can overcome the MDG’s shortcomings.

Food and water are tied to one another fundamentally. But in addition to their biophysical relationship, human systems intervene, whether through pricing schemes and trade agreements or shifting patterns in consumption and taste.

“With current neglect of family planning, the UN’s recent projection of a 2100 world population of up to 12.3 billion is a possibility,” says a report from the University of California, San Francisco’s Bixby Center for Global Reproductive Health. Increased voluntary family planning efforts are needed, the authors contend, to meet existing demand for contraceptives, stabilize the threat of global food insecurity, and reduce carbon emissions that contribute to climate change.

Although treating wastewater generally ranks alongside police and fire safety, schools, and transit as the top priorities of any sensible city hall, new ideas about cleaning up sewage almost never attract headlines or TV airtime. In its 90-year history, for instance, The New Yorker, the most urbane and expansive magazine in the country, has never published a feature article on sewage treatment.

Pope Francis sparked worldwide discussion and jubilation among many green advocates after releasing Laudato Si, the first Papal encyclical to focus directly on the environment. The pontiff touched on everything from pollution and sustainable development, to anthropogenic climate change and water security in his 180-page missive.

Researchers have been warning about future water scarcity for decades, but new data reveals a majority of the world’s largest aquifers are already running out of water.

A new report prepared by the UN Environment Program and UN peacekeeping operation in the Democratic Republic of Congo (known as MONUSCO) found that just two percent of the total value of illicit natural resources smuggled from the country comes back to armed groups. Still, these funds, which amount to around $13 million a year, allow some 25 to 49 groups to continue operating in the country’s war-torn eastern provinces. Much more, as much as 50 percent, ends up in the hands of transnational criminal networks with the remaining profits flowing to individuals or companies elsewhere in the DRC or in Uganda, Rwanda, and Burundi.

One of the primary ways climate change is expected to affect international relations is through water. There are more than 270 bodies of water that cross over international boundaries, and various methodologies have identified several dozen that are particularly at risk for tension or conflict. So how is climate change affecting transboundary water politics? Are governments and institutions taking the threat seriously? A few years back, a group of researchers decided to focus on this question.
