“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 China’s campaign to get its population of 1.4 billion vaccinated against COVID-19, the magic number is 77.6 percent. Government agencies all over the country, from Inner Mongolia to Jiangsu, uniformly pledge to get this exact percentage of their populations vaccinated. A rural township in Harbin boasts that it’s fully vaccinated 11,025 of its population of 14,198, 0.05 percentage point above the sacred target of 77.6 percent. So, just what is the significance of 77.6?

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.

“Never let a good crisis go to waste,” said Winston Churchill. Like other acute stressors, the COVID-19 pandemic acts as a multiplier of chronic or pre-existing vulnerabilities, such as the challenges of servicing rapidly growing informal populations, particularly in urban settings. This multiplier effect may accelerate water insecurity at unprecedented levels. However, together with UNESCO Intergovernmental Hydrological Program (IHP), we’re reflecting on the possibility that COVID-19 can act as an accelerator of positive action toward achieving Sustainable Development Goal 6 on water. The nexus between issues and urban water security is particularly important.

In Africa, climate change and population expansion are increasing fragilities and vulnerabilities—including contributing to conflict dynamics—for many people who directly depend on nature. To cope with how their environment can no longer supply livelihood needs, people are migrating in search of security or economic stability. These factors interact with one another in ways that underline the need for inclusive conflict mitigation considerations in climate change action.

The recently released National Intelligence Council’s Global Trends 2040 report, clocking in at over 140 pages, is titled “A More Contested World.” That headline should come as no surprise to development professionals. The report, reviewed by the incoming Director of National Intelligence Avril Haines, before being sent to President Biden and Congress, examines key trends that will likely influence U.S. national security out to 2040. I blogged on the Global Trends Report back in 2015, when it was on the verge of being unveiled at the splashy South-by-Southwest (SXSW) festival in Austin. This year’s public release was much more muted and the overall outlook decidedly more bleak, chaotic, and turbulent, not just from the lingering fallout of a “long tail” COVID-19 pandemic, but from the ominous environmental consequences of climate change on everything from glaciers and rising sea levels, to more frequent and intense tropical storms, and an unprecedented numbers of wildfires, like those seen last year in the Western United States. The NIC report also speaks to the ominous societal changes coming our way, best characterized by a widening chasm between what governments can reliably deliver and what citizens can reasonably expect.

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.
