Late Titicaca, which spans Peru and Bolivia, is increasingly threatened by climate change.

Lake Titicaca, spanning the border between Peru and Bolivia, is critical to supporting the livelihoods of 3 million people. That makes it all the more alarming that this year it was named the “Threatened Lake of the Year” by the Global Nature Fund and the Living Lakes Network, for the second time in just 11 years.

Houthi supporters in Yemen.

For the past year, Yemen has been in a state of limbo, its messy, regionalized conflict on hold but unresolved. And that’s unlikely to change—for the better, at least—soon. Even if Saudi Arabia and the Houthis agree to a formal cease-fire, the country will remain stuck in the liminal space of “no war, no peace” for some time to come.

Armenia and Azerbaijan's longstanding conflict over Nagorno-Karabakh ended in September 2023.

The UN recently approved a mission to Haiti, led by Kenya, to combat gang violence.

Last week, after months of requests from Haiti for international assistance, the U.N. Security Council authorized a peacekeeping mission to fight gangs that have taken over the country’s capital.

Migrants, mostly Venezuelans, walk across the Darien Gap from Colombia into Panama.

Around the world, the popular backlash against global migration has fueled the rise of far-right populist parties and driven some centrist governments to adopt a tougher line on immigration. But with short-term strategies dominating the debate, many of the persistent drivers of migration go unaddressed, even as efforts to craft a global consensus on migration are hobbled by demands for quick solutions.
