"This paper is a part of the research conducted in Sedayu district, Bantul, Yogyakarta. The aim is to classify soil erosion hazard in the area, construct land capability classes and establish some of the social-economic factors that influence farmers in implementing soil conservation activities. Survey method and purposive stratified techniques of sampling were used. Social-economic factors were quantified using scoring and later analyzed using SPSS program. Results indicate that the dominant land capability class in the area was class 1 found on land units consisting of alluvial plains with slope steepness ranging from 1-3% and having wet rice and mixed gardening as major land use. They had a very low degree of erosion hazard. Land units with mixed gardening as a major land use and found on karst landforms with slope steepness ranging between 8-15% were identified as having a very high degree of oil erosion hazard. The dominant land capability classes were 1, 2, 3, while classes 7 and 8 were limited to small area. Among the social=economic factors, it is found that the education factor has the greatest influence towards the farmer’s response to conservation activities in the research area."

"Soil erosion is a crucial environmental problem in the Manjunto watershed, Bengkulu Province, Indonesia. It has economic implications and environmental consequences. Assessment of potential soil erosion rate is useful in designing soil conservation strategies within the framework of integrated watershed management. Information obtained from Remote Sensing (RS) and Geographic Information System (GIS) framework supports decision makers in preparing more accurate spatial maps in less time and cost. The aim of this research is to assess the average annual rate of potential soil erosion in Manjunto watershed for each soil mapping unit using remote sensing data, namely Normalized Difference Vegetation Index (NDVI) and Slope. The NDVI value obtained from satellite imagery processing while slope value obtained from Digital Elevation Model-Shuttle Radar Topographic Mission (DEM-SRTM) processing. The results showed that the eroded catchment area increased significantly. The average annual rate of potential soil erosion in Manjunto watershed in the year 2000 amounted to 3.00 tons ha- 1 year-1, while in the year 2009 there was a significant increase to 27.03 ton ha-1year-1. The levels of erosion hazard in soil mapping unit numbers 41, 42 and 47 are classified in the very heavy category. Soil mapping unit numbers 41, 42 and 47 should be a first priority in soil and water conservation activities."
