Abstract

Ecosystem services are studied by using many different approaches and methods. Here we present a community approach with a combination of fieldwork methods and sociological surveys (questionnaire interviews and semi-structured interviews) in the assessment of mangrove ecosystem services. There were 198 households in 8 communes in 3 coastal districts of Nghe An province selected for the survey. We find that the basic mangrove ecosystem service values in the locality have identified by communities, including 17 types of services belonging to 4 groups: provisioning services, regulating services, supporting services and cultural services. The recognition and use of ecosystem services vary by location and occupation in the study area. The fishing group gives detailed information about the provisioning services, in contrast, the shrimp farming and agricultural production groups are interested in regulating and supporting services. According to space, mangroves in Quynh Luu district are assessed to have the highest potential for ecosystem services, followed by Dien Chau district, the lowest is Nghi Loc district. In addition to the potential for ecosystem services, mangroves are facing many threats of decline, placing responsibilities on managers and people in protecting and rationally using mangrove resources.
