The Mekong River’s seasonal floods nurture the world’s most productive inland fishery and irrigate rice paddies that feed millions. Approximately 70 million people live in the lower Mekong Basin, and 75% of them depend on fishing and farming for their livelihoods. But hydropower expansion and other development projects are fragmenting the river and disrupting its natural rhythms, with severe consequences for those living downstream.

The World’s Children Face the Most Severe Impacts from Wildfire Smoke (Mongabay)

Evidence of the alarming impacts of wildfire smoke on child health is growing. Children’s developing lungs, faster breathing rates, and greater outdoor exposure make them uniquely vulnerable, and the threat is intensifying as wildfires grow more extreme, incinerating not just forests but urban areas, releasing toxic heavy metals and chemicals. 

For decades, China has been the dominant force in hydropower development across the Mekong subregion, financing, and constructing massive dam projects that have transformed Southeast Asia’s economic and environmental landscape. Many analysts have framed this expansion as a meticulously orchestrated strategy to extend Beijing’s economic and geopolitical influence. But this narrative obscures a more complex reality—one in which China’s dam-building in the Mekong has been shaped by trial and error, reactive policy shifts driven by external shocks, local resistance, and intensifying geopolitical competition.

Heat-Related Deaths May Have Tripled during Europe’s Heat Wave (Washington Post) 

A record-breaking heat wave in late June and early July pushed temperatures well above 100°F across Europe. Analysis from Imperial College London and the London School of Hygiene and Tropical Medicine found that of the 2,300 heat-related deaths in 12 major European cities between June 23 and July 2, 1,500 would not have occurred without the additional 1.3°C of warming caused by climate change.  

In a rural, hard-to-reach area of Blantyre district in southern Malawi, Ephraim Louis cannot imagine where his life would be without the solar panel on the roof of his house. “I am not a captive of darkness anymore,” says Louis, 42. “It’s been more than 10 years since I installed this [solar panel] system. We still don’t have the main grid anywhere near us and no one here thinks it will ever come.” 

A few days ago, I bought a cucumber at the grocery store. Hermetically sealed in a layer of plastic as if bracing itself for interstellar travel rather than a trip to my kitchen, I struggled to open it, my patience thinning with the plastic. At one point I considered using my teeth. That’s when it hit me: was this really necessary?

When Secretary of State Marco Rubio formally declared the “era” of USAID over on March 28, 2025, it represented an extraordinary sea change for US foreign aid deployed over the past six decades.

Yet the world has changed dramatically since the U.S. Agency for International Development (USAID) was established by the Foreign Assistance Act of 1961 in the middle of the Cold War. So, there is every reason to thoughtfully consider what foreign aid should look like today as we navigate an era of Great Power Competition (GPC).

Marine Protected Areas in Tanzania Boost Living Standards (Mongabay)

In the 1990s, Tanzania established five multiuse Marine Protected Areas (MPAs) to help the country protect 30% of its oceans by 2030. However, a new study has found that the MPAs offered benefits beyond marine ecosystems by also improving the quality of life in nearby communities.
