The government of Madagascar has partnered with the World Bank in the Integrated Urban Development and Resilience Project for Greater Antananarivo (PRODUIR), which is being implemented between 2018 and 2023. This study contributes to PRODUIR by identifying and analyzing potential options for nature-based solutions to reduce flooding in the project area, and by identifying options for effective disaster evacuation from flood-prone areas. The results of the study are organized in three parts: (1) an evacuation and shelter strategy for the project area; (2) a plan integrating NbS and disaster evacuation for three pilot sites; and (3) recommendations for the implementation and upscaling of the proposed measures.
