Iran’s southeastern province of Khuzestan—which borders Iraq—was already a dry and dangerous place. It was the site of the fiercest battles in the Iraq-Iran war which followed the Iranian Revolution in 1979, and to this day, the region still has many unexploded landmines.

Yet this legacy of violence is not the only issue facing its residents. As climate impacts mount in Khuzestan, the future looks bleak for both the region’s ecosystems and the people already living on this borderline.

When Russia launched its brutal invasion of Ukraine on February 22, 2024, Western nations supported Ukraine with military and financial aid. But over two years, the cost of the war has been devastating—not only in terms of lives lost, and injuries sustained, but also in the number of buildings destroyed. According to some estimates, more than 150K structures have been damaged in the conflict.

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.

Iraq is incredibly vulnerable to the impacts of climate change. Temperatures are increasing, rainfall is decreasing, and the country experiences prolonged periods of drought. These conditions, as well as the destruction of wells and irrigation systems in the Islamic State’s (IS) targeted 2014-2017 campaign to destroy agricultural livelihoods, have created a growing water problem in Iraq’s Nineveh Plains. Indeed, water levels there have dropped low enough to subject crops to drought stress, endangering drinking water systems and affecting the ability to grow crops and raise livestock.

Demographic issues intersect with a number of policy priorities on the congressional agenda, including the economy, immigration, health care and foreign policy, but how population trends influence policy outcomes is often overlooked or misunderstood. In a new report, we explore how population dynamics have changed dramatically over the last few decades, and what these changes mean for the economic and security interests of the United States.
