Facts:About 45 percent of Indonesian land located on slope and hilly areas with elevation ranged from 350 to 1500 meter above sea level. The huge rainfall volume (>1500 mm/year) in several months.Population growth forces farmers to cultivate in steep slope upland by replacing native vegetation to annual crops with less soil conservation
consideration.
Results:land slides and soil erosion in the upland areas critical/marginal land, Marginal upland increasing rate: 400.000 hectares per year80 watersheds were in critical condition due to erosion and 36 out of which were in priorities rank (11 in Java island)upland productivity and economic viability tends to decreasepoverty of upland farmersnegative externality: sedimentation in rivers, dams and water canals system caused severe flood in rainy and drought in dry seasons
reducing lowland agricultural production.
Roots of upland problems: Less priority of upland development programs (compare to wetland), centralized and sectoral approach of government policies in the past, High erosion potency in upland (high intensity of rainfall, steep land, non-proper cropping pattern) Low productivity and small size of land ownership (0.3 - 2 hectares per farmer) lack of capital and less farmers motivation Extensions were inhibited by socio culture, infrastructure, and subsistence farming orientation
Need to develop land and water conservation farming to avoid land degradation and the lost of productive land, as well as to increase farmers welfare
Conservation farming system: integration of agriculture farming and conservation activities in upland area (hilly/mountainous)
Considerations :• sources of critical land problems • critical land status• soil characteristics and erodibility level• climate• socio economic status
• Problems of conservation farming: low adoption rate (example: adoption rate of bench terrace: 33%).
Integrated watershed management/IWM promising : a comprehensive approach, multi-resource management planning process in which link all stakeholders hand in hand:
• negotiate and define their interests, • set priorities, • evaluate alternatives, • Implement , • monitor outcomes
