Abstract:
This research study evaluation of soil erosion on the sloping area along plantation forest in steps (Terraces). The objective of this study is to monitor soil physical and soil erosion in terraced reforestation and reforestation areas along the slope at 25% 35% and 45%, respectively. The plot is for a period of 2 years. In this study, monitoring rainfall, soil physical, soil chemistry and soil erosion by Universal Soil Loss Equation (USLE). The result show that soil erosion of 35% reforestation area along the slope was 626.52 tons/hectare/year, in 25% reforestation area along the slope were 437.53 tons/hectare/year. Soil erosion of 45% 35% and 25% terraced reforestation were 399.79, 364.82 and 352.94 tons/hectare/year, respectively. The result concluded that topography, slopes of this area and rainfall effect detachment of soil erosion. The area using the World Heritage Agriculture System is based on the FAO criteria. 1) Food security These living conditions and 2) the biodiversity of agricultural ecosystems. (Agrobiodiversity) 3) Knowledge system and local wisdom 4) Culture, value system and social organization 5) Distinctiveness in landscape and sea view. The World Heritage Agriculture System will be able to maintain the balance of the ecosystem in the agricultural landscape alongside the cultural ecosystem of each area, restoring the upstream forest sustainably.
