On October 2, 2024, Dominican President Luis Abinader launched a large-scale deportation operation through the National Security and Defense Council. Framed as an “emergency” security measure to “protect national sovereignty and address migration challenges,” the operation aimed to deport 10,000 Haitian migrants every week.

Our present ecocrisis drives human insecurity. Single weather events killed hundreds in 2024, even in wealthy countries such as the United States or Spain. And beyond that staggering toll in human lives lurk staggering amounts of money required to repair and rebuild. In the United States alone, inflation-adjusted disaster-attributable costs have reached on average $153 billion each year. These factors and others make global environmental change a severe risk to human security.

What’s Next for the Teesta Water Disputes? (The Hindu) 

The recent political upheaval in Bangladesh which led to the resignation of Prime Minister Sheikh Hasina and the return of Nobel Peace Prize laureate Muhammed Yunus as leader of an interim government is not the only tumult in this nation. A worsening trend in weather events there has heightened Bangladesh’s exposure to climate shocks and allowed a dispute over the Teesta River to reemerge.

Americans often hear arguments demagoguing exorbitant and wasteful development assistance spending. In an election year, these voices multiply.  And they have influence. Past polls have shown that Americans believe that their government spends roughly 25 percent of the federal budget on foreign aid. The real total actually hovers around less than 1 percent.

Environmental shocks have been linked to significant changes in human migration around the world. Yet the large literature on environmental change and migration to date has primarily focused on working-age adults, working largely on the assumption that climatic impacts are most likely to influence labor migration.

A new report by the US Intelligence Community highlights what the world stands to lose if it fails to cooperate on global health. The National Intelligence Estimate (NIE) “Dynamics Shaping Global Health Security In the Next Decade” outlines the dire effects of climate change, changing demographics, and the erosion of trust in institutions on global health security. The NIE on Global Health Security was made publicly available in April 2024, on the heels of the Biden-Harris Administration’s launch of a new Global Health Security Strategy.

Food, Climate, and Conflict Nexus a Priority at the UN Security Council (Food and Agriculture Organization)

The United Nations Security Council’s High-Level Open Debate takes place in Guyana this week, and the signature event of that nation’s presidency is “The Impact of Climate Change and Food Insecurity on the Maintenance of International Peace and Security.” Several briefers have emphasized the interconnectedness between climate change and conflict, including Secretary-General António Guterres and UNFCCC Chair Simon Stiell.

Individuals face immense challenges in displacement contexts, particularly where climate, conflict, and displacement intersect. In Mozambique, climate impacts have combined with conflict to displace nearly a million people. Entire livelihoods, identities, and stability are vanishing. Women, men, girls, and boys are not just losing homes; they are losing their place in traditional societal roles, too. This chaos—and responses by the international community—are reshaping Mozambique’s gender dynamics.
