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.

“What’s become clear to me on population is that it’s really a local issue,” said Andrew Revkin in an interview at the Wilson Center. “You get the impression, ‘Oh didn’t we solve that problem?’” And to some extent, demographic shifts around the world are largely heading in the direction people anticipated, with a leveling off mid-century. But “no one really knows what happens then,” he said. “All it takes is a tiny diversion of fertility rates and things could really grow or shrink.”

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]

In many parts of the world, climate change exacerbates existing inequalities – between men and women, rich and poor, landed and landless. Climate change responses, therefore, should carefully address these forms of vulnerability.

We hear this often, but in practice, it can be difficult to do.

Six years after beginning a marine conservation program focused on octopus fishery management in southwest Madagascar, “we can proudly say that we have made a real impact as an organization providing health care,” said Dr. Vik Mohan, medical director of Blue Ventures and a practicing doctor in the United Kingdom.
