An assessment of the coastal ecosystem services of Jayapura City, Papua Province, Indonesia

Abstract

This study aims to assess and quantify the economic value of coastal ecosystem services (CES) in the coastal areas of Jayapura City based on the perceptions of Papuan indigenous peoples. Data collection was conducted from March to April 2018 using the direct interview method based on questionnaires to 228 respondents in Enggros, Tobati, and Nafri villages. The CES value in Jayapura City is estimated to be around USD 5,427,212.34/year, which consists of service values of mangrove, coral reef, and seagrass ecosystems that are USD 4,447,802.85/year or USD 19,079.46/ha/year, USD 424,333.06/year or USD 11,303.49/ha/year, and USD 555,076.43/year or 5,008.36/ha/year, respectively. The value of CES as a provider of fishery products is quite high because of the high desire of the community to exploit and utilize natural resources such as fish, crabs, shrimp, and shellfish in coastal ecosystems to as a food resource. Therefore, with the description of the CES value in this study, good coastal ecosystem management and integrated coastal area development policies are needed to maintain the quality of the environment and the sustainability of coastal ecosystems, as well as efforts to increase public awareness of the importance of coastal ecosystems and the important role that they play in improving the welfare of the Papuan indigenous people.
