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.

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.
