Many studies on natural disasters and conflict have assumed that disasters make it easier for rebel groups to recruit new members by fueling grievances against the government and lowering the opportunity costs of joining an insurgency, and that this recruitment will increase conflict. But disasters may actually have the opposite effect. My study of rebel groups in the Philippines, recently published in the Journal of Peace Research, suggests that by weakening the organizational structure and supply lines of rebel groups and their ability to enlist new fighters, disasters may instead reduce the intensity of the conflict, rather than increase it.

Water variability is increasing “due to climate change and to more frequent natural disasters,” said Jonathan Cook, Senior Climate Change Adaptation Specialist with the U.S. Agency for International Development, at the fourth and final event in a series on water security organized by the Wilson Center and the Sustainable Water Partnership. To solve the problem of increasingly erratic water, “business as usual is really not acceptable anymore,” said Will Sarni, founder of WetDATA.org, who called for new, innovative ideas: “Hope is not a strategy.”

In 1995, World Bank official Ismail Serageldin warned that “the wars of the next century will be fought over water—unless we change our approach to managing this precious and vital resource.” Since then, the world’s water resources have come under ever-greater strain. At the same time, institutional frameworks for managing water resources remain weak throughout most of the globe. Only about a quarter of the world’s international river basins have adequate governance arrangements to prevent and resolve conflicts. Does this mean that we can expect the 21^st century to be wracked by water wars?

Iraqi Kurdistan is blessed with abundant water resources, but these resources are under increasing stress. Changing demographics, dam building in neighboring countries, and drought have driven Kurdish hydropolitics to a critical juncture where two distinct water futures are possible—and both have implications for regional stability and for U.S. interests.

Put simply, “the damn thing melted,” Navy Secretary Richard Spencer explained in recent testimony, referring to Arctic ice melt as the trigger for the new U.S. Navy Arctic Strategy that is to be released this summer. What the Navy planned as a 16-year road map is in need of updates after only four years, in part due to receding polar ice caps, which are “opening new trade routes, exposing new resources, and redrawing continental maps,” but also in part due to the rise of China as an “Arctic stakeholder” and increasing important player in the region.

In 2014, after losing a number of Somalian cities it had captured to African Union and Somali troops, the terrorist group Al-Shabaab changed its tactics. To demonstrate its continued power and presence, Al-Shabaab cut off water supplies to its formerly held cities. Residents from these cut-off cities were forced to fetch water from nearby towns, many of which Al-Shabaab controlled. But the terror group prevented anyone living in government-controlled territory from entering, which increased people’s frustration with the government.

Blockchain, the newest technology poised to revolutionize numerous industries, could help decentralize electricity systems across Asia, Europe, Australia and the United States. In Brooklyn, peer-to-peer microgrids allow prosumers—energy consumers who generate small amounts of electricity from renewable sources—to trade energy with other users. Blockchain technology provides distributed ledgers that validate, record, and share each transaction, using smart contracts that automatically execute energy trades when the price and volume of the electricity transaction meet the contracted requirements.
