The population growth in Hulu Sungai Utara District has led to an unsustainable exploitation of natural resources, negatively impacting environmental quality. This study aims to analyze the environmental support of ecosystem services, specifically focusing on water and food provision in the region. The analytical method involves calculating indicative environmental support based on ecosystem services. It includes the classification of ecoregion characteristics (landscapes and natural vegetation types), land cover assessment, and the creation of service/performance maps using the Simple Additive Weighting method. The results indicate a predominance of high to very high categories in the ecosystem service of water provision, covering 71.77% of the total area. Similarly, the ecosystem service of food provision is characterized by moderate to very high categories, with the moderate category covering 30.13%, the high category covering 36.32%, and the very high category comprising 24.83% of the total area in Hulu Sungai Utara District. These findings provide crucial insights for policymakers and local communities to formulate informed strategies and policies for sustainable water and food resource management.

In overcoming the problem of critical land and watershed degradation, the government has launched Forest and Land Rehabilitation activities, abbreviated as RHL, in an effort to restore, maintain and improve the function of forests and land to improve their their carrying capacity, productivity and role in maintaining life support systems (PP 26 of 2020 on Rehabilitation and Reclamation). The Kapuas watershed is no exception, which contains protected forests, especially in Mantangai District in Katunjung Village, Sei Ahas Village, and Katimpun Village, where the area consists of peat swamp forest. The aim of this research is to describe the research area, community involvement (participation) in the Kapuas watershed, namely in Katunjung Village, Sei Ahas Village, and Katimpun Village. Formulate a strategy for community involvement in the success of watershed rehabilitation. The results of the analysis show that for Katunjung Village the values of the application of the strategy in quadrant II is a diversification strategy, that is, even though there are outstanding challenges, there are internal strengths that can be developed into breakthroughs and optimized to overcome challenging factors that are also quite strong. Meanwhile, for Ketimpun village, the strategic position is in quadrant IV with the respective X and Y values being (X= -0.5; Y= -0.486). The strategy in quadrant IV is a defensive strategy. In this quadrant, the implementation of rehabilitation experiences enormous challenges with weaknesses that are also very influential, so it is necessary to overhaul existing strategies.
