Climate Change

_climatechange lr

Climate change is a driver of human migration that many people expect will dwarf all others in its impact. While the effects of climate change on migration have generated significant attention, some of the most commonly repeated predictions of the numbers of people who will be displaced are not informed by an understanding of migration dynamics. Displacement is almost always a result of a complex mix of factors; people adapt to changes and governments (and a few other powerful actors) can influence what kind of movements take place in response to environmental changes.

Discovery of Oil Could Bring Migrant Labor Opportunities and Climate Displacement Challenges for Guyana

The discovery of massive oil reserves off the Guyana coast will bring immense riches to this small South American country. This windfall will draw migrant labor and the return of some diaspora members to Guyana, which has one of the world's highest emigration rates. It also could accelerate climate displacement in a country where 90 percent of the population lives in coastal areas below the sea level. This article explores the changes ahead.

Climate Extremes, Food Insecurity, and Migration in Central America: A Complicated Nexus

Climate change has had a devastating impact on many poor Central American farmers, which can contribute to food insecurity and may be prompting migration from the region's Dry Corridor. But the process is not straightforward. As this article explains, most poor farmers rely on a combination of buying, cultivating, and foraging for their food, which makes it difficult to predict how people will react to individual climate events.

Who Counts as a Climate Migrant?

Researchers often seek to predict how many people will move due to climate change, but beyond the inherent forecasting difficulties, their work is complicated by the fact that terms such as "climate migrant" are nebulous and migration drivers are often multifaceted. Instead, this article explains why analysts might ask how climate change will reshape existing patterns of migration and immobility.
