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.

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 sleepy northern Thai border town of Huay Luk, a community leader, Pornsawan Boontun, still remembers the day when villagers netted a Mekong giant catfish more than a decade ago. The fish weighed 615 pounds, and it surprised everyone since the elusive species has never been common in this stretch of river.

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.

Nearly every local story has a global context. This is especially true when it comes to the environment, and there may be no better way to show that context than through visualization. But in developing countries, where so many important changes are happening, journalists often lack the resources or skills to make data visualization a part of their repertoire.

Next year, the Millennium Development Goals (MDGs), adopted by the United Nations after the Millennium Declaration, are set to expire. As they wind down, the global development community is taking stock. While there have been great strides toward accomplishing many of the goals set forth in 2000, there has been little headway in ensuring environmental sustainability, said Melinda Kimble, senior vice president of the United Nations Foundation. Which raises the question: What should change for the next set of global development goals, which are supposed to be even more environmentally focused – the “Sustainable Development Goals?”

“I always say what brought me to Papua New Guinea is the tree kangaroo, and what keeps me there are the people,” said Lisa Dabek.
