Abstract: Water playing important roles in human activities. The change of land use or land cover and weather can caused the change at human water source condition. This fact has strong related in the availability of water. The main problem availability of water in number, quality and its distribution influenced by dynamics of land cover and people activities in Bua-bua and Parappa rivers basin. Bua-bua and Parappa is the important rivers in Selayar Island Regency, South Sulawesi. All of the people activities depend their life in water from the rivers. The average of monthly water change very influenced by rainfall period. Based on Maracov analysis, projection of Bua-bua land cover in 2023, the mangrove secondary forest decreasing about 10,52 hectare and increasing grasslands about 122,46 hectare, respectively. Increasing significantly for urban about 1570,51 hectare.
