Zusammenfassung: | One of the problems in Tesso Nilo National Park is deforestation through the opening of oil palm plantations. This can affect the ecosystem services of Tesso Nilo National Park, one of which is as a producer of water. Water yield is a key component of the attributes and processes that produce water-related ecosystem services. The importance of Tesso Nilo National Park ecosystem services as water producers needs to be assessed quantitatively and visualized to explain changes in land cover to changes in these services. The purpose of this study was to analyze the annual water yield in Tesso Nilo National Park. The model used is the Integrated Valuation of Environmental Services and Tradeoffs (InVEST) water yield model. InVEST is a spatially explicit tool for exploring how changes in ecosystems tend to lead to changes in benefits flowing to people. The annual water yield in Tesso Nilo National Park in 2018 was 5731528155.86 m

or 2729.52 mm. Water yield is strongly influenced by actual evapotranspiration (AET), mean annual rainfall (MAP), and land cover (LC). The land cover that produced the lowest to the highest water yield was mixed acacia, forest, oil palm plantations, bare land and shrubs. |
