Earlier this week, the Department of Defense released its first Quadrennial Defense Review since fiscal cliffs, shutdowns, and spending cuts hit the federal government. Not surprisingly, “austerity” shows up in almost every chapter of the report. What shows up even more? Climate change. For the second QDR in a row, the Pentagon has called out climate change as a “significant challenge for the United States and the world at large.”

Many recurring problems in natural resource management are the result of missing a key point: ecosystems and human systems are inextricably linked and dynamic, changing constantly. We are part of a socio-ecological system, not external to it, as many previously thought. In the “age of man” – the Anthropocene, as some scientists call the current era – cross-sectoral collaboration is needed to make substantial headway in tackling complex challenges, such as natural resource-related conflict and climate change.

What do melting Himalayan glaciers have to do with food security in Cambodia? Not much, thought an aid practitioner trying to boost food security along the lower reaches of the Mekong River – until she heard a colleague working on the Tibetan Plateau describe the downstream implications of climate change in the Himalayas. Everything she was working on, she suddenly realized, could be literally washed away.

These days, when the going gets tough, women “increase the peace.” From U.S. Secretary of State Hillary Clinton to Liberia’s President Ellen Johnson Sirleaf, the international community has learned that women’s leadership can contribute a different voice to fostering peace, alleviating poverty, and fighting for the rights of the oppressed.

In 2008 and 2010, the price of many basic food stuffs soared, sparking a series of riots and food crises around the world. People in the poorest countries – those living with the smallest margins – were most affected, while the economies of developed nations were able to absorb the price changes. According to Notre Dame’s Global Adaptation Index, how climate change will impact different countries depends not only on their vulnerability to physical changes, but also their ability to absorb these impacts. [Video Below]

A 20-year peace accord between Mozambique’s two major political parties was brought to an abrupt end last fall. A series of violent skirmishes between FRELIMO and RENAMO resulted in at least 10 deaths, dozens injured, and fears that the country might relapse into the kind of political violence seen during its civil war, which left more than a million dead. RENAMO claims its frustrations stem from a fraudulent electoral system and social inequality, but some observers have suggested their motivations may be less benevolent: making sure they get their piece of the country’s newfound natural gas wealth.
