Pola Dan Evaluasi Penggunaan Lahan Di Sempadan Sungai Cinangka, Sub Daerah Aliran Sungai Cimanuk Hulu (Pattern and Evaluation of Land Use in Cinangka Buffer Zone, Upper Cimanuk Sub Watershed)

Abstract

In general, watershed problems are caused by two factors namely natural factors such as rainfall, slopes and soil types and human factors such as policy and socio-economic factors. This study aims to evaluate the existing land use compared to Regional Spatial Planning of Garut in the buffer zone of Cinangka River, which is part of the Upper Cimanuk sub watershed. This research is expected to contribute to the watershed management knowledge and offer an alternative model for watershed management based on dynamic socio-economic conditions.Primary data collection was conducted through field surveys and interviews to the selected farmers whose land were in the selected areas. The interviews were to find out the reasons for planting the chosen crops. An observation plot of 50 meters for each river boundary as long as 1 km, were made to evaluate the land use. Therefore, total area of observation was 100.000 m2 or 10 hectare (ha). The study area is dominated by monoculture farming, which is 62% of the total area. Other land uses include bare land and shrubs (13.2%), agroforestry (12.3%), forest trees (trees & MPTS) (11.6%), and other types of land use (1%). The use of monoculture agriculture in this area is not accordance to the Regional Spatial Plans (RTRW) of Garut Regency in 2011-2031, which allocates the area of Cinangka sub watershed as community forest cultivation
