As global climate change affects livelihoods across the world, migration patterns are also changing. In a recent study published in Global Environmental Change, Clark Gray, Valerie Mueller, and I found that since the 1970s, climatic variations have been increasing internal migration across many South American countries, with few exceptions. And many people are headed to cities.

Since the end of World War II, the number of wars between states has declined significantly, but the number of intrastate civil conflicts – as seen in Syria and Afghanistan – has increased.

Have something to say about the U.S. government’s approach to water around the world? Here’s your chance. The Department of State has issued a public call for comment on its global water strategy. An open session was held in Washington last Friday, but written comments can be submitted until November 12.

For inspiration, here are points made by our own (and American University’s own) Ken Conca, edited for space:

A traditional conservation approach to climate change (e.g., habitat restoration, species protection) has been a primary tenet of the International Union for Conservation of Nature (IUCN) agenda for decades. But this fall at the quadrennial World Conservation Congress in Hawai’i there were new discussions about tackling climate change in the context of national security and environmental peacebuilding.

Over the past decade, the number of undernourished people around the world has declined by around 167 million, to just under 800 million people. However, this positive trend glosses over a stark reality: Food insecurity is increasing in the world’s mountains. This pattern has been under-recognized by development experts and governments, a dangerous oversight with far-reaching social and environmental repercussions.

How will climate change affect you? Probably through water.

That’s the major message of a new World Bank report that finds the ways governments treat water can have a profound effect on the economy.

When I heard of the horrific murder of Berta Cáceres, a Honduran environmental activist who had spent years fighting to protect her community’s traditional lands, I was shocked – though perhaps I shouldn’t have been.

Zika is a global health challenge. Since its outbreak in Brazil last May, the virus has spread to more than 30 countries and territories and ignited global discourse about family planning, vaccine development, reproductive rights, contraceptive security, and even gender norms.
