“There is little doubt that tens of millions of people will be displaced over the next two to three decades due in large measure by disaster and other environmental changes affected by climate, with the majority displaced within the borders of their own countries. The United States has a special responsibility to lead on issues of climate change, migration, and displacement,” said Eric Schwartz, President of Refugees International, at a recent event presenting a Blue-Ribbon Task Force report on climate change and migration.

In our top post for June, Steve Gale shares 5 consequences out of the National Intelligence Council’s recently released Global Trends report that development actors should be particularly attuned to. In addition to the “long tail” of the COVID-19 pandemic, the report recognizes the environmental consequences of climate change, including unprecedented numbers of wildfires, increased intensity of tropical storms, and sea-level rise. As a result, migration will be more pronounced and require more targeted aid approaches as demographics shift.

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.

Coordinating international financing for climate adaptation and mitigation remains a persistent challenge. In its 2020 Adaptation Gap Report, the United Nations Environment Programme observes that the annual cost of climate adaptation in developing countries could rise from $70 billion today to $280-500 billion by 2050—and current funding levels are growing at too modest a pace to keep up.

Already facing water stress, much of Latin America (such as the western slopes of the Andes and the dry corridor of Central America) is projected to experience intensified periods of drought in the coming decades, further complicating development efforts in the region. At the same time, heavy floods are the most common natural disaster in the region, disrupting life for countless people. According to the World Bank, in Latin America and the Caribbean alone roughly $14 billion per year is required to meet the 2030 water and sanitation targets of the United Nations Sustainable Development Goals. Typically, investments at this scale have been made by governments and large firms that invest in traditional infrastructure such as dams. But with ever-growing development needs and increased understanding of the impacts of climate change, Nature-based Solutions (NBS) are gaining momentum as a new way of incorporating environmental considerations into development responses.

The Hariyo Ban Program is one of the best examples of a sustainable development initiative that I’ve ever seen, said Nik Sekhran, Chief Conservation Officer of the World Wildlife Fund-US during a recent Wilson Center event on lessons learned from a decade of building resilience through participatory and inclusive natural resource management, climate adaptation, and biodiversity conservation in Nepal.

“If solar radiation management were done well—that is, the science is right, the engineering is right, and the policy and governance frameworks around all of the stuff work—then solar radiation management could be a really important, positive contribution to humanity’s responding to climate change,” says Simon Nicholson, associate professor at American University’s School of International Service and co-founder of the Forum for Climate Engineering Assessment in this week’s Friday Podcast interview with ECSP senior advisor and Ohio University professor, Geoff Dabelko. “But, there are all kinds of risks associated with this endeavor.”

Amid the COVID-19 pandemic, communities across the globe are experiencing unprecedented climate disasters.

According to modeling by ProPublica, the Pulitzer Center, and The New York Times Magazine, in the event that governments take “modest action to reduce climate emissions, about 680,000 climate migrants might move from Central America and Mexico to the United States by 2050.” That number leaps to above a million people in a scenario where no action is taken. The impacts of climate change on people’s decision to move are not constrained to the developing world, or even across borders. A recent study found that one in 12 Americans currently residing in the southern U.S. will move to California and the Northwest over the next 45 years because of climate influences.
