Economic and ecological trade-offs of coastal reclamation in the Hangzhou Bay, China

Due to the growing demand for land resources, coastal reclamation has become a global land use practice. Although the reclamation of coastal wetlands brings substantial economic benefits, it can lead to a series of adverse ecological impacts. Considerably, economic and ecological trade-offs of recla...
