The voluntary use of family planning, among its many benefits, is good for sustaining the healthy ecosystems that support all wild plant and animal species. This should be common sense. If your mission is environmental conservation, you should want to help remove barriers to reproductive health services, so that all women can space wanted pregnancies and avoid unintended ones.

Climate change is being increasingly framed as a security issue—a “threat multiplier” that can amplify the risks of breakdowns in peacefulness. Yet, even extreme climate hazards do not always lead to higher levels of violence.

Oil has played a pivotal role in shaping geopolitics for more than a century. But the rise of electric vehicles and shift toward cleaner fuels means that the world’s dependence on oil could begin to shrink, with both expected and unexpected consequences.

How do we plan for disasters that have never occurred before? One million species are at risk of extinction in the near future from environmental changes. The frequency of historic tropical storms is increasing. The rapidly melting permafrost in the Arctic is placing unprecedented pressures on northern infrastructure. Given the overwhelming and unpredictable nature of new disaster risks, it is not clear what the appropriate responses should be. Our book, Disaster Security: Using Military and Intelligence Planning for Energy and Environmental Risks, addresses how to assess unique environmental hazards and disaster risks, based on tools used by the U.S. intelligence and military communities. The book draws on lessons learned from developing, applying, and translating scenarios and simulations (or wargames) to plan for future environmental security risks.

As researchers investigate the connection between climate change and conflict, the relative power of communities and individuals attempting to cope with climate change has become a recurring theme. While climate change may not directly cause conflict, it may be inextricably woven into pre-existing conflicts of power, ethnicity, and economic interest.

Contrary to popular belief, Lake Chad is not shrinking, according to Shoring up Stability: Addressing Climate and Fragility Risks in the Lake Chad Region, a new report from adelphi. This finding has profound implications for how the governments of countries bordering Lake Chad (Nigeria, Niger, Chad, and Cameroon) as well as the international community should address the conflict trap in which the people of the region are caught. “Supporting the people of the basin,” write the authors, “is not a function of saving Lake Chad from desiccation.” 

In parts of the tropics, exposure to extreme temperature or rainfall in early life is associated with fewer years of schooling in later childhood. This finding comes from my new article in the Proceedings of the National Academy of Sciences, with coauthor Clark Gray. As climate change leads to increasingly severe heat waves, floods, droughts, and hurricanes, it is important to understand how extreme weather impacts kids’ education in different parts of the world. This will help decisionmakers develop solutions to keep children in school in a world of increasing climate variability.

As Arctic ice melts, we can physically see glaciers retreating. But what we can’t yet see is the exact effect climate change will have on the environment, humans, economies, and national security. Less ice for longer periods each year will likely bring opportunities and related challenges as Arctic and non-Arctic states jockey for position.
