The global water wars are almost upon us!

At least that’s how it seems to many. The signs are troubling: Egypt and Ethiopia have recently increased their aggressive posture and rhetoric over the construction of the Great Ethiopian Renaissance Dam in the headwaters of the Blue Nile, Egypt’s major artery since antiquity. India continues to build new dams that are seen by its rival Pakistan as a threat to its “water interests” and thus its national security. Turkey, from its dominant position upstream, has been diverting the Tigris and Euphrates rivers and increasing water stress in the already-volatile states of Iraq and Syria.

If current projections hold, Africa’s population will more than double in 40 years, putting more people at risk of food, water, health, and economic insecurity as the climate changes, as well as negating progress made in reducing carbon emissions per person. But what if it didn’t? [Video Below]

In southwestern China, three parallel rivers – the Nu, Lancang, and Jinsha (also known as the Upper Mekong, Salween, and Yangtze, respectively) – form a series of corridors that connect the tropical rainforests of Southeast Asia to the Tibetan Plateau. These areas are some of the most biodiverse in the world, and scientists argue they have value as “climate refugia” – places worth preserving in order to allow species to retreat to cooler, more suitable climates as temperatures rise. A cascade of dams, however, has been planned for the region, threatening to submerge habitats, reduce the flow of tributary rivers, and make the area less suitable for many plant and animal species.

The idea that China, the world’s largest producer of greenhouse gas emissions, could generate a significant portion of its energy from renewable sources might seem like a distant dream, but according to a new report, it’s not so far off. [Video Below]

The pork industry in China accounts for 65 percent of domestic meat consumption, but also produces 1.29 billion metric tons of waste every year. China’s growing appetite for meat has put tremendous pressure on the livestock sector, which now produces three times more waste than industrial sources, and created a series of environmental and food safety issues.

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.
