Reducing pluvial flood risk in rapidly evolving areas: strategic planning for uncertain futures 1: Institute of Environmental Engineering (IfU), Swiss Federal Institute of Technology (ETH) Zürich; 2: Department of Urban Water Management, Eawag (Swiss Federal Institute of Aquatic Science and Technology) Rapid urbanisation and climate change exacerbate flood risks, particularly rapidly evolving areas. This study provides a methodology to evaluate the effectiveness of Blue-Green Infrastructure (BGI) strategies in mitigating pluvial flood risks, using Antananarivo, Madagascar, as a case study. Results showed that buildings and people affected by flooding can be minimised by planning BGIs before land use change, and through the use of spatially distributed strategies, or strategies favouring blue infrastructure. The Net Present Value (NPV) analysis indicates that while most strategies are economically viable, hydrology-focused strategies yield the highest returns, and that implementation rates between 7-10% of the total case study area show the best balance between costs and benefits. These findings provide valuable insights and tools for urban planners and policymakers in designing sustainable flood mitigation strategies in rapidly developing, data scarce peri urban areas. | |
