Evaluation of the climate change impacts on vulnerability of water supply systems in Asia

The vulnerability and adaptation of water supply systems in Ho Chi Minh City (HCMC) in the Saigon River Basin and Hanoi City in the Red River Basin were evaluated in this study. In the Saigon River Basin, salt water intrusion and manganese leaching from acid sulfate soil will be exacerbated by climate change. In Hanoi, multiple sources of water are used in households including groundwater, rain water and tap water. Although it is necessary to use point-of-use water treatment devices, using multiples water sources may be an effective measure to mitigate the climate change impacts.
