Abstract

The ecological integrity of many watersheds is declining due to land conversion, deforestation, and urbanization, which increase surface runoff, reduce infiltration, and trigger discharge instability. A quantitative evaluation that simultaneously links KRA, KAT, sediment load, flood frequency, and IPA parameters with water governance aspects to assess the degree of hydrological resilience in the archipelago. This study aims to assess hydrological resilience based on the carrying capacity of the water system in the Tiworo Watershed, Muna Island. The method used refers to the Minister of Forestry Regulation No. P.61/Menhut-II/2014 by measuring the variables of flow regime efficiency, annual flow coefficient, sediment load, flood intensity, and water use index. The results show that the carrying capacity of the Tiworo Watershed water system has a performance value of 96.25, which is categorized as moderate. This carrying capacity value can be interpreted as functionally having sufficient capacity, but is vulnerable to ecological and anthropogenic pressures.

Abstract. Manan A, Sudia LB, Hasani UO, Kete SCR, Gandri L, Yasin A, Agusrinal, Isabela. 2025. Diversity, carbon stock and economic value of the mangrove ecosystem in Wakatobi Biosphere Reserve, Indonesia. Biodiversitas 26: 1095-1104. Mangrove ecosystems significantly contribute to climate change mitigation through the absorption and storage of carbon. This research evaluates the diversity, carbon stock, and economic valuation of mangrove ecosystems within the Wakatobi Biosphere Reserve. Data collection occurred at 11 stations distributed among four primary islands: Kaledupa, Wangi-Wangi, Tomia, and Binongko. Diameter at Breast Height (DBH) measurements were utilized to estimate biomass and carbon storage, employing species-specific allometric equations. Economic valuation utilized carbon trading data from the Indonesia Stock Exchange (IDX Carbon) as of 3 January 2025, alongside the Social Cost of Carbon (SCC) and Voluntary Market (VM) prices. The mangrove ecosystem of the Wakatobi Biosphere Reserve covers an area of 10,994 hectares and is in excellent ecological condition. The Shannon-Wiener Diversity Index values for tree and pole strata demonstrate moderate diversity (1-3), with Kaledupa and Binongko classified as moderate, whereas Wangi-Wangi and Tomia are categorized as low (<1). The evenness score indicates a high classification for tree strata (>0,6), with the exception of Wangi-Wangi, which is classified as medium (0,4-0,6). Wangi-Wangi Island is classified as low for splinter strata (<0,4), whereas Tomia, Kaledupa, and Binongko Islands are classified as medium. The composition of mangrove species differed across islands, with Sonneratia alba, Rhizophora mucronata, Bruguiera gymnorrhiza, and Ceriops tagal identified as the most prevalent species and significant contributors to carbon sequestration. The total carbon stock was estimated at 329,82.06 tons, with Kaledupa Island exhibiting the highest stock at 317,226.51 tons, while Binongko Island recorded the lowest at 2,053.8 tons. The economic valuation of carbon storage indicates significant potential: IDR 18,763,377,420 or USD 1,159,307 (IDX Carbon), IDR 266,390,582,055 or USD 16,459,103 (SCC), and IDR 43,155,274,293 or USD 2,666,375 (VM), underscoring the financial importance of mangrove conservation. This signifies a potential for revenue generation in the Wakatobi region, offering a hopeful prospect for the future. This study highlights the ecological and economic significance of mangroves and establishes a basis for sustainable conservation and management strategies aimed at improving the resilience of the Wakatobi Biosphere Reserve.

Abstract

Managing coastal tourist areas requires an approach that can integrate ecological and socio-economic aspects so that environmental quality and community welfare are maintained. This study aims to analyze the ecological and socio-economic conditions in the Nambo Beach Tourism Area, Kendari City, and to formulate sustainable management strategies through an integrative ecology–social approach. The research was conducted in October–November 2025 through field surveys, water quality measurements (temperature, pH, salinity, DO, BOD, TSS, TDS), vegetation cover analysis based on the 2024 SHP, observations, as well as interviews and questionnaires with the community. The results show that most water quality parameters still meet marine tourism standards, although there is pressure on the TSS value (96 mg/L) and indications of increasing organic material shown by the BOD value (3.70 mg/L). Coastal vegetation cover, including mangroves, still dominates with an area of 5,910 hectares. but it’s starting to be pressured by increased tourism activities and development. On the socio-economic side, the community relies on income from tourism businesses, small trade, and transportation, but they face challenges such as low environmental awareness, limited public facilities, and suboptimal waste management. The integration of analyses using the ICM and SWOT approaches shows that Nambo Beach is in the aggressive strategy quadrant, meaning it has great potential for development.
