Abstract
The completion of Jatigede reservoir construction is targetted in 2014. The reservoir is constructed as water supply for 90.000 ha irrigation area in adequate quality and quantity in the hope of improving agricultural production, and increasing planting intensity as one important factor in support of food resilence in West Java Province and Indonesia. Based on analysis result of land-use change pattern in Jatigede Reservoir catchment area in 1994 – 2009 period, land-use had changed 23.865,8 ha from protected areas to cultivated areas, where protected area had decreased from 44.104,5 ha in 1994 to 20.238,8 ha in 2009 and cultivated area had increased from 102.742,7 ha in 1994 to 126.608,61 ha in 2009 with changing rate 1.591 ha/year. The rate of decreasing primary forest area was 502,1 ha/year, as a result there was no land function as primary forest in 2009. The rate of decreasing secondary forest area was 1.087,2 ha/year ranging from 35.869,7 ha in 1994 to 19.561,7 ha in 2009. Land-use change pattern in Jatigede reservoir catchment area dominantly was influenced by changing pattern of protected forest and secondary forest in protected area, but in cultivated area land-use change pattern was influenced by changing pattern of farm, grassland, and rice field.
