The Guangdong-Hong Kong-Macao Greater Bay Area (GBA) is the fourth largest bay area in the world, and contributed about 11.8% of the national GDP of China in 2018. GBA is frequently affected by extreme weather events such as typhoons and rainstorms, posing a huge challenge for the sustainable development of this area. This project will (1) review the existing adaptation measures adopted in different cities of the GBA, (2) evaluate the socio-economic benefits of these measures, (3) examine the applicability of the state-of-the-art adaptation strategies with consideration of uncertainties associated with future projections in the GBA, and (4) provide policy and technical recommendations to GBA cities for mitigation and adaptation of future more extreme events. The project will consider both hard and soft measures and examine the effectiveness of these measures. Different types of extreme events, such as typhoons and rainstorms, can be correlated and may occur in sequence. The project will formulate prevention strategies for the co-occurrence of different types of extremes. The deliverables of this project include evaluation reports, technical guidelines, academic papers, etc.
