Impacts of mangrove management systems on mangrove changes in the Northern Coast of Vietnam

This research examined mangrove management in Hai Phong city, Vietnam. A combination of logistic regression model data and field survey data were used to investigate the driving forces of mangrove changes. The results indicate that implementation of mangrove management investigated by the authorities, community or local people has affected mangrove change. The main driving force of mangrove loss is over expansion of shrimp aquaculture. The poorer families would like to participate in mangrove conservation activities more than richer households. Mangrove rehabilitation programs have been successfully managed by community-based forest management in cooperation with local authorities in some coastal communes. Nevertheless, the failure to convert shrimp culture from mangrove forest is recognized in other communities. These communes have to replant mangrove in abandoned shrimp ponds and follow the mangrove management used in former communes.
