Why do people stay in places where their homes, livelihoods, and their very lives are threatened by the impacts of climate change? Caroline Zickgraf, deputy director of the Hugo Observatory at the University of Liège in Belgium, discusses these so-called "trapped populations" in this episode of the Changing Climate, Changing Migration podcast.
Climate change and international migration both are global issues with aspects that countries try to manage through treaties, pacts, and other types of agreements. But most of the global governance frameworks that exist for climate-induced migration require only voluntary commitments by states.
Among the earliest examples of the disruptions that climate change can bring, some low-lying island countries in the Pacific Ocean are facing serious threats from rising sea levels and coastal erosion. Over the long term, atoll nations such as Kiribati, Tuvalu, and the Marshall Islands might eventually need to relocate some or all of their populations.
Climate change is already affecting how, whether, and where people migrate. But environmental change is likely to become more extreme, unless the world takes serious action now. How might changes made now impact what future migration looks like?
Reliable access to food—or lack thereof—can affect an individual’s decision to migrate. Climate change has the ability to exacerbate food insecurity, especially for farmers and others who live off the land, which can have repercussions for human mobility.
Billions of dollars are being spent on projects to help communities mitigate and adapt to the impacts of climate change, including those at risk of being displaced by environmental events.
Pre-COVID-19, we lived in a hyper-global world. There were 1.5 billion international tourism trips annually, nearly 40 million flights, and 272 million international migrants. This raises a provocative question: Does international mobility contribute to the spread of pandemics?
Confronting environmental change, whole communities sometimes relocate from one area to another. This purposeful, coordinated movement, while currently rare, is referred to as managed retreat.
With news that viable COVID-19 vaccines are on the horizon, what might 2021 hold in store for the global movement of people, whether for tourism, business travel, or more enduring forms of migration?
