“Where is the tea?” I asked after our class had hiked through densely wooded hills for half an hour, looking around in confusion. I was among a team of Duke Kunshan University (DKU) graduate students led by Dr. Binbin Li to study tea crops grown in the tropical forests of Xishuangbanna, Yunnan Province. 

Multilateralism is under threat, as many global powers increasingly choose to center their security priorities around defense and economic competition over international cooperation. This shift toward short-term national interests risks undermining progress on joint challenges, including climate change, peace and justice. What will be lost if the climate security agenda becomes a battlefield of competing interests? How can peacebuilding and development actors respond?

Rivers, lakes, and aquifers ignore borders and politics, binding countries, people, and ecosystems together. This shared reality has long required cooperation, even among states divided by tensions or conflict. Through technical dialogue, data sharing, and joint institutions, countries have often quietly managed floods, negotiated infrastructure, and protected water quality.

Journeying from November 2025’s International Conference on Family Planning (ICFP) in Bogotá to the UN climate negotiations in Belém the following month revealed a fundamental tension. Evidence increasingly shows that climate justice requires reproductive justice, yet translating that recognition into policy commitments continues to raise political apprehensions among stakeholders.

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.
