The common agricultural practicesof local farmer is traditional as well as parallel to the slope planting, low dosage of dung, compost and cemical fertilizer, and only a few farmers who grow roses and the fennel as a vegetative terrace. The consequences are high risk of erosion, land slide, sediment yield and runoff harvesting. The phenomenon will indirectly affect the hydrologic variability such as flash floods in the rainy season, sedimentation of the reservoirs and irrigation networks and declining on the recharge rate of aquifers that constitute the main water resource during dry season in the downstream area which is largely a food crop production center of Klaten regency
