Few regions are more environmentally insecure than South Asia.

The region faces rising sea levels and regularly experiences coastal flooding – of particular concern in a region with heavily populated and arable-land-rich coastal areas. Additionally, it is highly vulnerable to glacial melt. The Western Himalayas, which provide water supplies to much of South Asia, have experienced some of the most rapid melt in the world.

I recently spent a hectic and intense couple of weeks in the village of Andavadoaka, where Blue Ventures’ community health project is based, during my annual visit to Madagascar.

Finally, a slice of the wealth that has propelled Mozambique from its war-addled past to its newfound status as one of the world’s fastest-growing economies would be theirs.

“During my career, my viewpoint changed significantly in the understanding and definition of what security really is,” said retired Admiral William J. Fallon at the Center for Strategic and International Studies (CSIS) on November 2. “My current appreciation of it is that it’s much more fundamental, much more personal, much more at the individual human level than I had thought in earlier years.”

The size, composition, and spatial distribution of human populations are constantly changing, and in some areas of the world, they’re changing very rapidly. Related trends in fertility and reproductive health are also in flux. These changes will affect how people experience climate change, both individually and societally.
