An early warning system (EWS) is widely recognized as an essential element in enhancing the adaptive capacity of local institutions and communities to respond to extreme climate events.
A cross-country project on adaptation behavior in response to extreme climate events in Southeast Asia and China by the Economy and Environmental Program for Southeast Asia (EEPSEA) in 2009 examined, among other things, the effectiveness of EWSs in relation to typhoons and floods in six studies sites in China, Indonesia, the Philippines, and north and central Viet Nam.
For China, Indonesia and Thailand, localized EWSs which comprise monitoring, forecasting and sending out warnings of impending disasters are undertaken by local-level government agencies. In China, typhoon monitoring and forecasting are done by provincial weather stations and warning are disseminated to the households at risk. In Jakarta, there an early warning system to predict floods caused by tidal waves. In the case of Thailand, the Hydrology and Water Management Center for the Upper Northern Region is responsible for flood monitoring and early warning system dissemination in Chiang Mai City and neighboring provinces.
