Climate change is increasing the risks ofwater-related disasters, such as floods, droughts, and hightides in the Asia region. Estimating financial gaps of disasterrisk reduction is needed to consider investment policies, plansand financial arrangements. However, the estimates of the demandfor disaster risk reduction are rarely available, and academicliterature in this area is limited. Additionally, themethodology for estimation has not been established.
The study analyzes the trends of budgets of flood protection inmajor flood-prone economies in Asia, and proposes methodologyfor estimating demand for flood protection infrastructure. Thedemand in the region until 2030 is estimated using regressionanalysis to apply panel data of possible socio-economic factors,and financial gap is estimated. The study also aims at proposingthe policies of filling the financial gap by examining policiesand approaches in the region.
