“We’re fighting for our lands, for our water, for our lives,” said an indigenous woman from Colombia, describing her work as an environmental defender. She spoke at a December 2019 workshop on Gender, Peace and the Environment held in Bogotá, Colombia, that brought together social, environmental, and legal scholars and practitioners—including indigenous women—to discuss women, peace, and security issues.

Beginning with the end of the Cold War, a relatively small but growing number of scholars began to investigate the connections between environmental change, conflict, peace, and changing notions of security. The recognition of these linkages wasn’t new, but as the heavy weight of superpower confrontation lifted and new foreign policy dynamics unfolded across the globe, an expanded range of research questions and tools emerged.

Late last year, Reuters reported that the U.S. Defense Department plans to fund mining and processing operations for rare earth elements—a class of minerals for which China dominates the global market, producing over 80 percent of the world’s supply. In the past, China has restricted exports of rare earths, and recently threatened to do so again. Even with a phase one trade deal hammered out between the United States and China, natural resources are likely to remain a point of geopolitical tension.

Environmental peacebuilding is a good idea. As a practice, it aims to address simultaneously environmental problems and challenges related to violent conflict. Examples include the promotion of environmental cooperation between rival states, conflict-sensitive adaptation to climate change, and restoring access to land and water in post-conflict societies. As a concept, environmental peacebuilding directs researchers’ and politicians’ attention to cooperative adaptation as a response to environmental stress. It thus helps to correct one-sided narratives about environment-conflict links.

In the Global South, climate change-induced resettlement requires a holistic and integrated approach, involving all stakeholders—state institutions, local customary and civil society institutions—and in particular respectful engagement with local traditional actors and networks. In a policy brief for the Toda Peace Institute, we examined climate change-induced resettlement from the Carteret Islands in the Pacific, a case which encompasses a broad range of issues relevant to future relocation efforts elsewhere. Those who seek to make this type of resettlement possible would do well to heed these lessons.
