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

Abstract

This research examined mangrove management in Hai Phong city, Vietnam. Acombination of logistic regression model data and field survey data wereused to investigate the driving forces of mangrove changes. The resultsindicate that implementation of mangrove management investigated by theauthorities, community or local people has affected mangrove change. Themain driving force of mangrove loss is over expansion of shrimpaquaculture. The poorer families would like to participate in mangroveconservation activities more than richer households. Mangroverehabilitation programs have been successfully managed bycommunity-based forest management in cooperation with local authoritiesin some coastal communes. Nevertheless, the failure to convert shrimpculture from mangrove forest is recognized in other communities. Thesecommunes have to replant mangrove in abandoned shrimp ponds and followthe mangrove management used in former communes.
