A Successional Salty Agriculture System in the Pearl River Delta



The study area is in Guangzhou, the Pearl River Delta, China, a region with a complex landscape system featuring agricultural production and wetland. The coastal disasters such as storm surge and seawater intrusion have always been a risk for most of the agricultural land, which is lower than the local mean sea level. Therefore, an adaptive agriculture model is needed to deal with the greater risk caused by sea level rise.

Based on traditional reclamation agricultural model, our proposal is to integrate agriculture production with wetland transformation under sea level rise to create a successional salty agriculture landscape adapting to coastal environmental change and benefit agriculture, ecology and social culture for the next 100 years.

Our proposal includes three phases:

  • transforming the original agriculture to aquaculture on the tidal flat;
  • cultivating salt marsh on tidal flat to build a rotation of harvest agriculture and aquaculture;
  • replacing part of spartina with mangrove in a successive way to create a mixed rotation of fishery, harvest agriculture, aquaculture and wetland conservation.
