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.

Climate Breakdown Threatens Global Food Security (The Guardian)

Global agricultural systems now face mounting pressure as climate impacts intensify and crop yields plateau. Production of the world’s most abundant crop, maize, is projected to decline by 6% under low-warming scenarios, and as much as 24% in extreme warming scenarios. Extreme weather wiped out over 1 million hectares of Zambia’s maize in 2024 alone, accounting for half of the country’s total production. An Amazon drought devastated more than 18,000 hectares of crops in Peru, leaving 500,000 children facing both food and water shortages.

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.

The recent conflict between Iran and Israel, as well as Iran’s threat to close the Strait of Hormuz, have done more than starkly expose the risks of geopolitical instability in the Gulf.  It has also underscored the vulnerability of India’s energy security due to its heavy reliance on fossil fuel imports, and particularly crude oil transiting through the Strait of Hormuz.

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.
