A “code red for humanity”— that is how UN Secretary General António Guterres described the future climate scenarios laid out in the International Panel on Climate Change’s Sixth Assessment Report. According to the report, CO2 in the atmosphere has reached levels unseen in 2 million years, amplifying floods, droughts, and other environmental catastrophes around the world. 

In December 2020, Vietnam’s Prime Minister Nguyễn Xuân Phúc signed the country’s National Action Plan for Management of Marine Plastic, setting an ambitious goal for the government to reduce marine plastic litter by 75 percent by 2030. Recent surveys indicate that plastics are the most prevalent and dangerous form of waste choking Vietnam’s beaches and waterways. Whether polystyrene, discarded nets, or mismanaged single-use plastics, these items are not just an eyesore, but they imperil the local ecosystem and fishing industry in Vietnam. 

Indonesia generates nearly 7 million tons of plastic waste each year but only 10 percent of that is recycled. The proportion is even lower in rural areas due to a lack of collection facilities. Waste is often burned or dumped on vacant land, and into rivers, lakes, and seas. 

On my first tour of a Cambodian minefield in 2010, the demining supervisor of the platoon of deminers brought me through a tapioca field where heavily armored men and women stood in lines. I was not allowed beyond the bright red signs with skulls and crossbones. Wearing bulletproof helmets, masks, and aprons, they slowly and tediously walked through the field, using a metal detector to sweep the ground in front of them, the sun reflecting off the long plastic visor. To avoid the heat of the Cambodian sun, they began their work early in the morning. In the golden hour of sunrise as dawn gilded the fields, the sounds of a distant Buddhist temple surrounded us with chanting. I commented on how beautiful it was.

“This COVID-19 pandemic has reminded us, albeit in a devastating way, of the interconnected nature of things, most particularly between economies, the environment, human and wildlife health and welfare,” said John Scanlon AO, the former Secretary-General of the Convention on International Trade in Endangered Species (CITES) and Chair of the Global Initiative to End Wildlife Crime, at a recent Wilson Center event on wildlife crime’s connection to human health and security. Despite its serious implications for a broad swath of issue areas, wildlife crime and trafficking remain under-studied and under-regulated. At the event, experts from diverse fields in defense, global health, and conservation highlighted the need for international cooperation to mitigate wildlife crime’s impact on environmental degradation, the spread of zoonotic disease, and transnational security threats. 

Over the past decade, our understanding of how climate change affects conflict and security has advanced considerably. Yet, how to best address the overlapping challenges of climate change, conflict, and human security remains an open question. In an article published in World Development, I address this topic by examining how climate security discourses inform development policy and, in turn, how the structures of development enable or constrain institutional capacity to address climate security. This research identifies not only the unique barriers the development sector must overcome, but also the ways in which the most common framings of climate change (i.e., as a threat multiplier) limit the scope for policy and programming.

As climate change impacts become starker, interest in geoengineering is growing. Geoengineering is “climate manipulation technologies that we can use to alter the climate to offset the worst parts of climate change,” says Beth Chalecki, Associate Professor of International Relations at the University of Nebraska Omaha, and Research Fellow at the Wilson Center, in a recent episode of Wilson NOW. “It sounds like a technological fix, but of course it’s not that simple,” says Chalecki.
