概要	Policy makers need estimates of financial impact to consider investing in DRR, but such estimates are rarely available. This paper aims to estimate the financial gaps relating to infrastructure for flood protection in Asia and proposes polices and approaches to filling these gaps. It was found that nine major flood-prone economies in the region invested USD33.6 billion in flood protection, or 0.21 percent of their GDP, in 2015. Regression analysis suggests that the annual demand for flood protection infrastructure in developing Asia will be USD94.5 billion, or USD98.4 billion with climate change effects, for the period 2016-2030. The financing gap between future needs and current investment levels is around USD61 billion, USD65 billion with climate change effects annually, or around 0.24 percent of GDP in developing Asia. Developing economies thus need to turn flood disasters into opportunities for expanding this type of investment.
