Socio-economic modelProject Objectives●To achieve the highly accurate assessment of flood and drought risks by developing and using a hybrid
assessment model covering climate change, hydrological processes, agriculture (crop growth) and socioeconomic activity with a DIAS-based big-data platform.
To evaluate the benefits of pre-disaster investments by applying the hybrid assessment model to the target
local municipalities and make policy proposals for the sustainable economic development of local municipalities
in general.

Overall Goal
●To enhance the resilience and promote the sustainable economic development of local municipalities
by incorporating policy proposals in local and national climate change action plans, thereby contributing
to reducing the over-centralization in the metropolitan area and facilitate balanced national landdevelopment.
