Governments in the Asia-Pacific region face the risk of unprecedented numbers of people displaced by floods, storms and other impacts of climate change, the Asian Development Bank (ADB) said in a report on Monday.
The bank and climate scientists said the region, home to 4 billion people, will be among the regions most affected by the impacts of climate change, leading to major migration both within and between nations, stretching resources.
The draft report, “Migration due to climate change demands attention” also said no international mechanism has been created to manage millions of people on the move.
“Protection and assistance schemes remain inadequate, poorly coordinated, and scattered. National governments and the international community must urgently address this issue in a proactive manner,” it said.
Failure to do so risked costly humanitarian disasters, the report concluded.
The report for policymakers reviewed climate threats and the complex nature of migration, of which climate change is only one of many drivers, including greater numbers of people moving to cities to seek jobs.
It pointed to impacts such as higher temperatures, changing rainfall patterns, greater monsoon variability, rising sea levels, floods, and more intense tropical cyclones.
