Daya Dukung Lingkungan Daerah Aliran Sungai Kayan dan Sembakung Kalimantan Utara Dalam Penyediaan Pangan dan Air

The purpose of this research was to understand the carrying capacity of Kayan and Sembakung watershed in North Borneo Province, the carrying capacity in providing clean water and how was the trend of the carrying capacity of the water supply in the Kayan and Sembakung watersheds, which were the basis for food supply. The study area was the Kayan and Sembakung watersheds in the administrative area of North Kalimantan Province using an “ecosystem services” approach. The results of the research were as follows: (1) the Kayan and Sembakung watersheds in North Kalimantan Province were dominated by areas that have “high” carrying capacity in providing food; (2) The Kayan Watershed in North Kalimantan Province was dominated by areas that have a “moderate” environmental carrying capacity in water supply, while for the Sembakung watershed it was dominated by areas that have a “high” environmental carrying capacity in water supply; and (3) The carrying capacity of the downstream areas of the Kayan and Sembakung watersheds in the provision of clean water tended to be “Very Low” when the carrying capacity of the downstream ecosystems in the Kayan and Sembakung watersheds as food providers was “High”.
