Rising Food Insecurity is Driving Instability (Foreign Affairs)

Since 2020, the number of people facing acute hunger and chronic food insecurity has increased 130% above existing levels. And supply is not the issue. At present, the world produces enough food to feed nearly 10 billion people, yet there are 720 million people who are food insecure and a further 319 million face acute hunger. Today’s hunger is driven instead by barriers to access.

When I arrived in Mogadishu in 2013 to set up and lead the Office of the President’s communication and media department, I had the privilege of being invited to breakfast with the President. As I made my way through the layers of security leading to the presidential residence, I noticed an older woman walking behind me—cradling a chicken under each arm. She followed closely, undeterred by the checkpoints that stopped others.

A massive flood in Somalia killed hundreds of people, and displaced tens of thousands more. Yet the survivors faced a vexing prospect when they tried to return home: Al-Shabab had moved in.  

Stephanie Speck, Head of Special Initiatives at the Green Climate Fund, observed at a recent Stimson Center event that Shabab’s new levies meant that residents could not to move back to farm their land.  

When we look at climate-related insecurity, it’s usually in the context of poorer parts of the planet. And there’s generally good reason for that focus. Regions such as the Sahel and the Middle East are where the most––and worst––conflict of this nature plays out. And, for the most part, poorer countries are also the places least equipped to manage climate impacts and their effects on stability.

Assessment of UNESCO Sites Reveals Climate Impacts (Mongabay)  

Initial data from the first ever global biodiversity and climate assessment indicates that 98% of UNESCO’s 2,200+ World Heritage Sites, Biosphere Reserves, and Geoparks have experienced at least one climate-related extreme event since 2000, including massive wildfires, droughts, and retreating glaciers. The effort to track such effects will now be augmented by UNESCO’s new Sites Navigator, a geospatial platform that integrates over 40 datasets to track climate impacts, biodiversity loss, and socioeconomic conditions in real time.

Mexico’s Mercury Boom is Poisoning People and the Environment (Associated Press)

In Mexico’s Sierra Gorda mountains, soaring international gold prices also have created a mercury boom. Since 2011, mercury prices have skyrocketed from $20 per kilogram to between $240 and $350 per kilogram today. Most of Mexico’s mercury is trafficked to Colombia, Bolivia, and Peru for use in illegal Amazon gold mining operations that contaminate rivers and ecosystems. Yet the country’s adoption of a 2017 UN convention banning mercury mining and exports also allows artisanal mines to operate until 2032.

While the devastating cyclones Dineo (2017) and Idai (2019) may feel like distant memories on the global stage, their impact remains etched into daily life in Zimbabwe’s Tsholotsho and Chimanimani districts. A punishing regional drought in 2024 makes the picture here even clearer: food, land, and water systems have been reshaped in ways that directly influence social cohesion and stability.

Climate-related catastrophes are posing significant challenges in already-fragile South Sudan. When record-breaking floods again swept across the country in mid-2024, for instance, the disaster affected 1.4 million people, with the cumulative years of flooding submerging two-thirds of the country.
