Tracing the past: an insight on flood risk management strategies in the development instruments of Bangladesh and Dhaka city

Abstract

Abstract Confronting devastating floods regularly is a critical challenge for Bangladesh. Dhaka, the capital and a megacity at the forefront of rapid, unplanned urbanization, has been experiencing consistent challenges and threats of flood since 1954. Since then, to ensure flood protection and control, the city authorities have adapted diverse flood risk management strategies (FRMS). Regardless of the overall progress in flood risk management policies in the national development agenda, the inertness of their implementation means the city remains vulnerable. Along with that, several divergences from the development plans, for instance, the new town development in flood flow zone, the declaration to convert a residential zone into a retention area, illegal acquisition of wetlands for property development have also been observed. Therefore, the objective is to review the diversification of FRMS at the national level and to identify the convergence or divergence on the development plans at the sub-national level, in this case, Dhaka Metropolitan Area. This study provides a commentary to support policy-makers and researchers in integrating FRMS with the development plans at the local level.
