Soil erosion in agroforestry development in South Bandung Region, Indonesia

Forest is an ecosystem unit in the form of a stretch of land containing biological natural resources dominated by trees in its natural environment. Ecologically, the function of forests is to absorb rainwater to prevent erosion. Land conversion of forest to other uses causes disturbed ecological functions of the forest. The agroforestry system is a land optimization system by combining the components of perennial woody crops, agricultural crops and also livestock. Agroforestry systems have become one of the alternative systems to overcome problems that arise due to the high of land conversion. Bandung District recommends 3 types of agricultural crops in the development of agroforestry in the South Bandung Region, namely coffee and tea, which are perennial crops, and vegetable crops which are annual crops. The purpose of this study is to compare the erosion level of the three types of plants used for agroforestry. The method used in this study are land suitability analysis and erosion estimation analysis. The final results of this study conclude that the erosion level of perennial crops is lower than annual crops.
