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.

Myanmar is rich in natural resources—gas, oil, minerals, and gemstones—yet is still one of the world’s least developed countries. Extractive industries are the country’s most lucrative sector and the government’s main source of revenue, but most of the benefits do not reach its citizens. Instead, resource extraction in Myanmar causes severe environmental and social problems and fuels and sustains some of the country’s longstanding ethnic conflicts.

When Secretary of the Navy Richard Spencer told the media last week that “the damn thing melted,” he wasn’t talking about an ice cream cone. As the Arctic faces unprecedented levels of open water, Spencer and other naval leaders recently testified to Congress about the U.S. Navy’s strategy, which is changing as quickly as the Arctic itself. 

Are younger countries at higher risk of civil conflict? The International Crisis Group’s 2018 list of 10 conflicts to watch suggests they might be: Like last year, intra-state conflicts (civil and ethnic conflicts within states, rather than wars between states) dominate the list, and among those, about 70 percent are within youthful countries, or states with a median age of 25.5 years or younger. The only multi-state cluster mentioned in both 2017 and 2018 lists is the Sahel, the world’s most youthful region.

Food has long been used by countries to wage both war and peace, and the post-war era of American food dominance is no exception. Bryan McDonald, a professor at Pennsylvania State University, traces the United States’ “Food For Peace” strategy in his recent book, Food Power: The Rise and Fall of the Postwar American Food System, arguing that “food was central to national security” during this period.

Starting in 2014, the number of migrants from Central America’s Northern Triangle—Guatemala, El Salvador, and Honduras—surged, with border apprehensions increasing fivefold from 2010-2015. While apprehensions have declined from their peak, emigration from these countries has not necessarily slowed, and the conditions the migrants are seeking to escape have not changed. Experts blame the region’s widespread criminal violence for spurring migration. But the Northern Triangle countries also share similar ecology, staple crops, and vulnerability to climate events. While environmental and natural resource factors are just part of the complex picture, understanding how they intersect with other migration drivers is key to creating and implementing effective policy responses.
