The ongoing violence in Syria exhibits the potential for water problems – a historic drought, in this case – to exacerbate existing social and political problems and contribute to humanitarian crises. In a recently released infographic, Circle of Blue combined data from the European Commission Joint Research Center’s Global Conflict Risk Index and the World Resources Institute’s Aqueduct Water Risk Atlas to identify 10 hotspots around the world where water “could play a role in developing or exacerbating humanitarian crises” in 2016.

In his speech on climate change and national security on November 10, Secretary of State John Kerry said climate change is already a “threat multiplier,” and that worse is to be expected if climate change continues unchecked. But the relationship between the environment and violent conflict is complex and often indirect. Researchers have been wrangling for years over the role that global environmental change plays in fueling conflict and state fragility.

Barren barley and wheat fields stretch across the dry landscape of northern Afghanistan, the result of persistent drought and flash flooding that has left thousands of people facing food shortages and loss of work.

Hundreds of Yemenis have been killed since Houthi rebels overthrew President Abdu Rabu Mansour Hadi at the beginning of April. The instability next door has led Saudi Arabia to intervene with a bombing campaign and, most recently, impose a blockade of Yemen’s port cities to cut off what they claim is Iranian resupply of rebels. Besides blocking weapons though, the blockade is also having a major impact on food security and food assistance, and is even affecting livelihoods in Somalia.

Under international law, someone who flees their country because of conflict or persecution is a refugee, but someone who flees because of inability to meet their basic household needs is not. In the case of Somalia, it is increasingly difficult to make any meaningful distinction between the two.

Migration is an “extreme” form of climate adaptation, but it does pay off for some, write Md. Monirul Islam et al. in a new article in the journal Climatic Change. In a study analyzing two Bangladeshi fishing communities, one long-established, the other the result of migration, the authors examine the effects of climate-induced migration on livelihood vulnerability.
