I meet Keo Mao, 42, in the floating fishing village of Akol on Cambodia’s Lake Tonle Sap. The houses here move seasonally with the lake, which expands by a factor of five during the monsoon rains and recedes again in the dry months. Fish supply about 80 percent of the animal protein eaten by Cambodians, and about 60 percent of the inland catch comes from the Tonle Sap.

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.”

The Wilson Center’s Urban Sustainability Laboratory, in partnership with USAID, International Housing Coalition, World Bank, and Cities Alliance, is pleased to announce the 5th Annual Urban Poverty Paper Competition for graduate students. The competition calls on students currently enrolled in a Master’s or PhD program to submit paper abstracts on topics relating to urban poverty in the developing world.

In Lake Victoria and Lake Chilwa basins, interconnected development challenges defy sectoral boundaries, said experts at the Wilson Center on February 10. According to Deepa Pullanikkatil of Leadership for Environment and Development and Doreen Othero of the Lake Victoria Basin Commission, growing populations, shrinking resource bases, and persistent human health concerns demonstrate the need for integrated development approaches that combine population, health, and environmental (PHE) interventions. “We need different sectors working together to achieve the greater goal,” said Pullanikkatil. [Video Below]

How has China managed to feed nearly one-quarter of the world’s population with only seven percent of the world’s arable land?

In 1995, Lester Brown forecasted doom and gloom for China’s ability to produce enough grain for its people, in his popular book, Who Will Feed China? He hypothesized that China would be forced to buy grain from abroad, thereby seriously disrupting world food markets.

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.

Against the stunning backdrop of Marojejy National Park, I recently crossed paths with a conservationist from a very different background, working on the opposite side of Madagascar. But, it turns out, the communities we work with face many of the same challenges, and our meeting spawned a new population, health, and environment (PHE) program.

In the wake of natural disasters, the idea that systematic change might be needed to prevent future crises often takes a backseat to restorative efforts. But as disasters become more common, there is often a blurring of disaster response and development initiatives.
