| Abstract | An assessment of watershed area and agricultural land especially paddy areas are conducted through primary and secondary information. Primary observation was obtained from households and landholder survey, field observation and semi-structure interview conducted during August to November 2004 in five selected villages in the Upper Ciliwung Watershed. The watershed are undergoing degradation due to increasing pressure on the forest and agricultural lands, especially paddy areas, following population growth and high demand for settlement and built-up areas. Besides, there are some pertinent management issues to be addressed including decentralization of power in watershed management and coordination among different line agencies, land use conflict among different stakeholders, sustainability of watershed management program, increasing productivity, poverty alleviation and sharing the research outcomes. There have been changed of land use in the watershed area which are significantly different with the land use plans of the government. The agricultural land especially paddy areas is decreased by 17.2% during period of 1969 - 2002 (the land was only 292.84 ha). This condition is affecting achievement of self-sufficiency of rice in the area. The finding of the study shows that land use of paddy area in the Upper Ciliwung Watershed must be 3,950.75 ha to fulfill the current demand of rice (self sufficiency) in the area. Based on simulation result, agricultural intensification (grow rice for three planting seasons) can not be applied in the area. Hence, beside land expansion, another way to increase rice production to cope with increasing population pressures is increase the productivity per unit of land. The average landholding size in the area is 4,592 m2 with the range of 0.04 - 2 ha per farmer. Based on 50 households survey was conducted in the area, the minimum land holding size of the farmers to get minimum income of S 1 per capita per day is 36,962 m22 (=3.7 ha). Result from DSSAT simulation and mathematical programming found that there are some inputs (cultivar, plant population density, fertilizer) that can be improved to increase yield and finally increase the benefit of the farmers compared with existing farming practices in the area. An appropriate management in the agricultural sector can increase the productivity of their land by 1.76 - 2.45 times and increase the benefit of the farmers by 2.12 - 3.15 times and hence increase the income per capita of farmers not to be categorized as poor farmers |
