ADB breaks important ground on climate-induced migration

The global development community is just beginning to discover the extent to which climate change is a driver of displacement and migration across the world. According to the Internal Displacement and Monitoring Center, more than 42 million people were displaced in Asia and the Pacific since January 2010, and many of these individuals were forced to move by storms, floods, or other weather-related events or natural hazards. In the same report, IDMC reveals that the Asia-Pacific region accounted for 77 percent to 87 percent of the total number of people displaced worldwide from 2008-2010.

In 2010, the Asian Development Bank began researching the interrelationship between climate change and migration to identify policy and other responses to environment events on human mobility within the Asia-Pacific region. The result of an extensive ADB-financed technical assistance project was a report titled, “Addressing Climate Change and Migration in Asia and the Pacific,” which represents the global development community’s first effort to shed light on how climate change will impact migration patterns in the region and identify appropriate policy and development interventions that hold genuine potential to address the issue.

According to ADB, three primary factors explain why Asia-Pacific finds itself at the center of the discussion on climate-induced migration:

  1. It is the region most affected by disasters, which is a result of the high frequency of extreme climatic events, the large populations living in high-risk zones, and their limited ability to reduce their vulnerability. This leads to the displacement of millions of people every year, a trend that will be further reinforced by both climate change and population growth.

  2. The region is the most populous in the world, with mass movements of people spurred by growing inequalities and regional integration.

  3. Climate change is expected to take the heaviest toll in the region, exacerbating current environmental problems and stimulating a variety of economic, social and political challenges.

Among the most important and distinct contributions of the ADB report is how climate-induced migration is assessed as part of global migration dynamics. As ADB states, “Migration typically has multiple causes, and environmental factors are intertwined with other social and economic factors, which themselves can be influenced by environmental changes.” With these realities taken into account, ADB recommends addressing the issue of climate-induced migration as part of the broader development context and agenda.
