Abstract

Seagrass ecotourism is a tourism activity based on seagrass ecosystem as an educational tour by seeing the ecology of seagrass meadows and associated biota. Conservation awareness and improving community welfare, seagrass ecotourism is a nature-based tourism strategy with the aim of environmental conservation and containing aspects of community education and culture. Determining the sustainability status of seagrass ecosystem management is very important as a basis for future policy planning. The sustainability of seagrass ecosystems needs to be protected, so a policy strategy is applied in sustainable seagrass ecosystem management. The objectives of the study are: 1) determining the sustainability status of ecotourism-based seagrass ecosystem management based on ecological, economic and social dimensions, 2) determining the policy strategy for ecotourism-based seagrass ecosystem management. The results of the study obtained the sustainability status of ecotourism-based seagrass ecosystem management based on ecological dimensions is quite sustainable while the economic and social dimensions are less sustainable. The strategy for sustainable policy for managing seagrass ecosystems based on ecotourism on Maitara Island, Tidore Islands, namely education about seagrass ecosystems for the community, managing seagrass ecosystems based on ecotourism, increasing seagrass rehabilitation programs, maximum limits for carrying capacity of seagrass ecotourism, training for developing managers of seagrass ecotourism based on ecosystems, increasing job opportunities and business opportunities, legality of seagrass areas as conservation areas in the tourism utilization zone category and strengthening laws and institutions.Keywords:analysismultidimensionalsmall islandsustainabilitytourism

Abstract

Awanggoa Village in Bacan District, South Halmahera Regency, has experienced significant residential expansion, converting around 9 hectares of mangrove land into a residential area. The remaining mangrove ecosystem, covering an area of 16.84 hectares in the northern part of the village, is starting to experience degradation, especially along the coast and southern areas. This condition requires management policies that ensure the sustainability of the ecosystem. The purpose of this research is to analyze the NDVI condition of the mangrove ecosystem, as well as measure biomass, carbon stock, and CO2 absorption, using remote sensing methods via the GEE application (https://code.earthengine.google.com) with data collected from January 1 to December 31, 2023. The research results show a total biomass of 101.21 tons ha, carbon stock of 47.57 tons C ha, and CO2 storage of 174.88 tons C. Dense vegetation is very important for carbon storage and emission reduction, thus supporting sustainable mangrove ecosystem management and environmental conservation efforts.
