Climate Science and Policy

This study assesses the increasing flood risks in Ho Chi Minh City due to climate change and urbanization, and proposes the implementation of the sponge city concept as a solution to enhance flood resilience. Through a comprehensive analysis of literature, data, and models, coupled with GIS techniques, the study reveals the escalating flood risks in the city, both from inland and from the coast. The sponge city concept, which integrates nature-based solutions such as green spaces and water storage facilities, is presented as a means to improve flood resilience. The study analyzes the opportunities and constraints in the application process, provides recommendations to utilize opportunities and overcome constraints, and suggests some potential locations for implementation. The findings highlight the importance of incorporating nature-based solutions into urban planning and development strategies to create sustainable and resilient cities. While focusing on Ho Chi Minh City, the study's recommendations can be applicable to other urban areas facing similar flood challenges. Further research and feasibility studies are recommended to fully implement the sponge city concept.
