Warning of massive flooding for Asia's coastal mega-cities

GMA News TV (Philippines): The Asian Development Bank (ADB) warned Asia’s coastal megacities, including Manila, of more massive flooding incidents that could affect millions of people should current climate change trends continue. In a report titled "Climate Risks and Adaptation in Asian Coastal Megacities," the ADB said the cost of major flooding on infrastructure and the economy could run into billions of dollars, with urban poor populations likely to be the hardest hit.

Apart from Manila, the other Asian megacities identified in the report were Bangkok in Thailand and Ho Chi Minh City in Vietnam. The report, released Friday in Bangkok is the product of a two-year collaborative study by the ADB, the Japan International Cooperation Agency, and the World Bank. The ADB said the three megacities should find effective ways to address climate change issues such as rising sea levels and extreme weather changes.

…“Land subsidence due to groundwater pumping, dumping of solid waste into city canals and waterways, clogged drainage systems, and deforestation in the upper watershed all contribute to urban flooding," the statement said.

The report said the governments of the three cities should address climate risks as an integral part of urban planning. The measures include “developing strategic urban adaptation frameworks for managing climate risks, strengthening institutional capacity for adaptation, and implementing measures such as land use planning and zoning to help reduce urban vulnerability."…
