In all three cities, there is likely to be an increase in the number of persons exposed to flooding in 2050 under different climate scenarios compared to a situa- tion without climate change. For instance, in Bangkok in 2050, the number of persons affected (flooded for more than 30 days) by a 1-in-30-year event will rise sharply for both the low and high emission sce- narios—by 47 percent and 75 percent respectively— compared to those affected by floods in a situation without climate change. In Manila, for a 1-in-100-year flood in 2050, under the high emission scenario more than million people are.
