Abstract

AbstractThe objective this study was to predict erosion rate and erosion hazard level in DumogaSub-watershed. The study is expected to provide spatial information on erosion rateand erosion hazard level in Dumoga Sub-watershed, particularly for spatial planning as wellas soil and water conservation. Erosion was predicted employing USLE while spatial analysiswas conducted using Geographic Information Systems (ArcView 3.3). Rainfall data were collectedfrom three weather stations, erodibility values obtained by analyzing samples fromthree soil types, slope categories were determined using DEM (Digital Elevation Model), valuesof the landuse and soil conservation were determined by means of satellite image interpretationin and field survey as well. It was found that soil erosion ranged from 0.39 to16.800 tonnes /ha/year. The lowest erosion rate occurred on forest land and ricefield withhacingflatslope. The highest erosion rate was identified on farm land having very steep slope.Erosion hazard level varied from verylow to very severe. It is necessary to perform soil andwater conservation measured on the land experiencing severe to very severe erosion hazardas to reduce soil erosion.Keywords: Erosion, Geographic Information System, Watersheed

Abstract

ABSTRACTThe national income distribution reflects the equal or unequal distribution of the development result of the populations in a country. The purpose of this research is to calculate and to compare the basic income distribution with other incomes of the farmers. This research uses the primary data and secondary data with 30 farmers respondens.The result of the research shows that the Gini Coeficient in the research area is 0, 3943 for the basic income and 0, 3008 for the basic income with other incomes. Paying attention to the Gini Coeficient, means that the unequal income or the uneven income in the research area belongs to the moderate and low unequality.Based of Gini Coeficient, distribution income more equal in basic income with other income than just basic income. It means the other income more in the farmers at low income and middle income. Because of that suggested for the farmer specially in low income group to increase their income from other income another their basic income (red been farm).
