Possible economic damage due to climate change and flooding in the future was the subject of an important report issued last week.
The report focuses on risks in three of Southeast Asia's (ASEAN's) largest cities: Bangkok, Manila and Hom Chi Min City.
The title of the report is Climate risks and adaptation in Asian coastal megacities : a synthesis report (Read report).

Three cities urged to plan ahead by Achara Ashayagachat
...Asia's policymakers need to take serious and concrete steps to integrate climate-risk factors into the planning of their megacities or risk losing their economic edge.
The warning comes in a report titled "Climate Risks and Adaptation in Asian Coastal Megacities," the first systematic study of its kind, launched last week in collaboration with the World Bank, the Asian Development Bank (ADB), and the Japan International Co-operation Agency (JICA).
...the study of three cities - Bangkok, Manila, and Ho Chi Minh City (HCMC) - shows clearly how real the problem could be as soon as 30 years from now if nothing is done today to address climate-change problems...
Each of the cities has a registered and unregistered population close to or greater than 10 million. Each is a driver of national or regional economic growth and all depend on the capacity of local hydrological systems such as rivers and streams, watersheds, and wetlands to provide services critical to the lifelines of these cities and their residents.
Key findings from the 120-page report include:
1. All three coastal megacities are likely to witness increases in temperature and precipitation linked with climate change and variability.
2. By 2050, there will be an increase in flood-prone areas due to climate change in all three cities and hence the increase in the number of people exposed to the flooding.
3. Costs of damage are likely to be substantial and can range from 2-6% of regional GDP.
4. Damage to buildings is an important component of flood-related costs.
5. Impact on the poor and vulnerable will be substantial, but even better-off communities will be affected by flooding.
6. Land subsidence is a major problem and can account for a greater share of the damage cost from flooding compared to climate-related factors.
Since it is likely that extreme events will be more intense, the planning for these events will have to be strengthened.
This means a 'package' of measures is needed: early-warning systems, upstream watershed management to enhance water infiltration and flood retention, downstream protective dikes, higher pumping capacity, dredging and clearing of canals and drains, increasing drainage system capacity, and measures to counter coastal erosion and storm surges are needed," said the expert.
Elaborating damage costs for each city, the report says that for Bangkok, the increased costs associated with climate change (in a high-emission scenario) from a once-in-30-year flood total 49 billion baht, or approximately 2% of gross regional domestic product. These are the additional costs associated with climate change. The actual costs of a once-in-30-year flood, including costs resulting from both climate change and land subsidence are close to $4.6 billion in 2050.
