Economic contribution of beach resources and their sustainable development in China

Beach ecosystem provides services that produce substantial economic value. Different functions of beach re-sources (recreation and tourism, amenity, coastal protection, biodiversity, etc.) perform inherently different characteristics and contribute diversely to human welfare and fortune. Yet, there have been rare quantification estimations for economic contributions of beaches to human life. Here, framework of beach ecosystem services based on key functions is established, then a series of integrated quantification methods are summarized by published literature and a few novel estimations. Economic contributions of beach resources are obtained through application in fifty-nine coastal cities of China in recent ten years. Spatial added values in real estate benefiting from beaches are separated out economically for the first time. In China, beach resources of 3100 km generate an economic value of at least yen 4.00 x 1012 ($579.60 x 109) during the time interval 2010-2019. Furthermore, legislation, international tourism competitiveness, beach nourishment and restoration issues are discussed; dynamic pattern and healthy-recycled beach economy are creatively proposed according to the needs of sustainable development. This study explores the interface between ecosystem services and economics for beach resources, provides straight recognition upon beaches' economic contribution (least estimation), and promotes understanding of social and natural impacts on China's beach economy.
