Typhoons, cyclones, floods and drought are forcing more and more people to migrate, the bank said in a statement Monday announcing the report. In the past year alone, extreme weather in Malaysia, Pakistan, China, the Philippines, and Sri Lanka has caused temporary or longer term dislocation of millions of people.

The bank said it expects this process to accelerate in coming decades as climate change leads to more extreme weather.
"No international cooperation mechanism has been set up to manage these migration flows, and protection and assistance schemes remain inadequate, poorly coordinated, and scattered," the report states. "National governments and the international community must urgently address this issue in a proactive manner."
Speaking Saturday at the Delhi Sustainable Development Summit, Bart Edes, director of ADB's Poverty Reduction, Gender, and Social Development Division, said, "Climate-induced migration will affect poor and vulnerable people more than others."
"In many places, those least capable of coping with severe weather and environmental degradation will be compelled to move with few assets to an uncertain future," predicted Edes. "Those who stay in their communities will struggle to maintain livelihoods in risk-prone settings at the mercy of nature's whims."
Edes cited an article in the May 2009 issue of "The Lancet," a leading medical journal of record, that called climate change "the biggest global health threat of the 21st century."
Edes sketched a four-part scenario for the summit participants.
The bank's report underlines specific risks confronting climate change "hotspots," including megacities in coastal areas of Asia.

These hotspots of climate-induced migration face pressure from swelling populations as rural people seek new lives in cities, the report indicates. The problem is compounded by greater dislocation of people caused by flooding and tropical storms.
On the positive side, the report says that if properly managed, climate-induced migration could actually facilitate human adaptation, creating new opportunities for dislocated populations in less vulnerable environments.
The ADB report accords with the 2009 prediction of UN High Commissioner for Refugees Antonio Guterres, who said that "climate change will become the biggest driver of population displacements, both inside and across national borders, within the not too distant future."
"Today's challenges are interconnected and complex," Guterres warned again in December 2010. "Population growth, urbanization, climate change, water scarcity and food and energy insecurity are exacerbating conflict and combining in other ways that oblige people to flee their countries."
The Asian Development Bank will publish the report, "Climate Change and Migration in Asia and the Pacific," in early March as part of a broader ADB project aimed at increasing awareness of migration driven by changing weather patterns, and enhancing regional preparedness for this unprecedented type of migration.
The bank says that its project, Policy Options to Support Climate-induced Migration, is the first international initiative that aims to generate policy and financing recommendations to address climate-induced migration in Asia and the Pacific.
