The Amazon endured the most intense fire season in almost a decade in August 2019. On August 19, smoke from the faraway fires blackened the skies over Sao Paulo. By the next day, the hashtag “#PrayforAmazonia” was sweeping across Twitter. The social media outcry brought world attention to the already dire scientific warnings, and world leaders offered aid and pressured Brazilian President Jair Bolsonaro to take action.

If you have even a passing familiarity with the climate and security literature, you undoubtedly have come across the phrase “threat multiplier.” The phrase conveys the idea that climate change intersects with other factors to contribute to security problems. It’s used as short-hand to avoid the charge of environmental determinism, that climate change somehow on its own causes negative security outcomes.

Recognizing the need to address environmental challenges in the wake of war and disaster, American University’s School of International Service and World Wildlife Fund (WWF) joined together to launch the project “Environmental Dimensions of Sustainable Recovery: Learning from Post-Conflict and Disaster Response Experience.” As representatives of a leading conservation NGO (World Wildlife Fund) and a professional graduate school with extensive expertise in environment, development, and conflict resolution (American University’s School of International Service), Anita van Breda and Ken Conca’s partnership helped to conduct a truly cross-organizational, cross-perspective exchange and familiarized them with the challenges and opportunities that occur when working across sectors and organizational cultures.

As an inhabitant of the Himalayan region of Nepal, where 8 of the 10 highest peaks of the world are situated, I am experiencing first hand several environmental stresses and insecurities. Many of the high mountains I can see from my village, once covered in snow, are turning black. Neighboring areas are experiencing massive out-migration and demographic changes. Consequently, agriculture in the region is facing an unprecedented crisis.

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.

Since the dawn of the Industrial Revolution, humans have so vastly altered Earth’s systems that we’re now in the midst of what many are calling the Anthropocene Epoch. Human activity has become the dominant influence on climate and the environment, inflicting changes that may persist for millennia.
