for flood risk assessment. The method was also introduced to the related organizations in several developing countries of Asia such as the Philippines, Indonesia, Cambodia, Thailand, and Myanmar. The results of flood damage provide a basis to identify areas at risk, and these results can be useful for planners, developers, policy makers, and decision-makers to establish policies required for flood damage reduction. The results may also be useful for them to implement flood mitigation actions including agricultural land-use regulations while taking into account the risk areas of

• The accuracy of flood hazard assessment and damage assessment highly depends on the quality of topographical data. For the case studies in this chapter, agricultural damage was assessed using remotely sensed topographical data and global land-cover data. Damage assessment can be further improved by adjusting remotely sensed topographical data with ground observed elevation data for certain points and also by using locally available land-cover

• Generally, flood damage curves are prepared based on actual flood damage and inundated depth. Data and information on actual flood events and damage with their relationships are very important for developing damage functions, as well as for validating calculated results. It is thus important to collect damage data and hazard information during or after a flood disaster.

• Risk indicators such as flood damage curves can differ from place to place according to the characteristics of exposed elements such as agricultural products and residential houses, even though some similarities may be found between some places. It is recommended that each country should develop damage curves to reflect the actual characteristics of their rice-crop cultivation.

• This chapter focused on assessment of flood damage to rice crops. However, for flood risk management in the river basins, it is also necessary to consider flood damage to other agricultural crops and also flood damage to buildings,
