Economic Aspects of Integrated Flood Management


 Brief description


Economic analysis provides the rationality for taking action as it provides some perspectives on the scale of impact and feasibility. The expected benefits of the flood management interventions can be evaluated vis-vis the expected costs, to facilitate the decision-making process. However, it has to be kept in mind that economic analysis on the other hand it contains many assumptions and has certain limitations. It fails to address the issues of equity and often those benefits and costs that are not readily apparent and are beyond assessment such as environmental service. Multi-criteria analysis (MCA) complements economic analysis.
