“…Soil erosion is the direct result of the mismanagement of the soil by man in his effort to obtain a living from it [1]. Studies reported that, cultivation without using specific control techniques and unplanned land use, such as uncontrolled urban development, deforestation and mal-agricultural practice are fundamental factors of soil erosion [2].…”

Soil degradation in the form of soil erosion is a serious and continuous environmental problem in Jabi Tehinan Woreda. Uncontrolled land use, deforestation, over cultivation, overgrazing and exploitation of biomass for firewood, construction and other household uses due to increasing population ultimately lead to severe soil erosion. The impact of natural hazards like erosion can be minimized and ultimately controlled by disaster preparedness maps. Therefore, the overall objective of this paper is to quantify and map an estimated soil loss by examining different topographic and anthropogenic factors for the planning and implementations of sustainable soil conservation and management system in the study area. This study had integrated Geographic Information System (GIS), Remote Sensing (RS) and Multi-Criteria Evaluation (MCE) techniques to quantify and map erosion vulnerable areas using RUSLE model. Slope gradient, slope length, soil type, soil conservations techniques, cover management and rainfall variables were used as input model parameters/variables. The data had been collected and analyzed from different land sat imageries, SRTM data, topomaps and point interpolations of primary data. Finally, the aggregated effects of all parameters had been analyzed and soil loss from the area was calculated using RUSEL models. After analyzing all model parameters, areas in steeper slope with Lithosols, Eutric Nitosols, Orthic Luvisols, croplands, bare lands and river banks have been identified as the most erosion vulnerable areas. Quantitatively, an estimated annual soil loss in Jabi Tehinan Woreda ranges from nearly 0 in south and central parts of the area to 504.6 t/ha/yr in steeply sloping mountainous areas of the north and north-eastern parts of the catchments.

“…Whilst, among many factors affecting soil and water relationship, the organic matter may play a crucial role which is mainly controlled by the procedure of vegetation cover management (McCalla et al, 1984;Cooke, 1985;Thurow et al, 1986;Commandear, 1992;Kukal et al, 1993;Gustafson, 2000;Bennett, 2001). Therefore, the role of economically feasible and applicable managerial approaches on hydrologic response of rangeland areas is a need, which has to be properly taken into account.…”

The effects of grazing and cultivation management on infiltration, runoff and sediment yield on storm basis were quantified for summer rangeland in the Matash mountains (Talesh Region), northern Iran. The infiltration experiments were made using double cylinder infiltrometer with five replicates within each study treatment. The runoff generation and sediment yield were measured using standard plots (1Á83 m Â 22Á18 m) in three replications.The peak and the terminal instantaneous infiltration, and runoff and sediment rates were compared using independent and paired sample t-test in two aforesaid treatments, respectively. The terminal and the peak instantaneous infiltration rates of 39Á6 and 342Á9 mm/h showed a respective significant increase ( p < 0Á001) of 32 and 39 per cent in cultivated areas compared to those in open grazing treatments. The results of runoff analysis also showed that there was a significant difference ( p < 0Á001) in runoff generation in two above-mentioned areas. The runoff water was also found to be 5Á63-folds more in case of open grazing treatment in comparison with that generated by cultivated plots. A significant difference ( p < 0Á001) in sediment yield between two study treatments was also proved by the results obtained through sediment yield study. The soil loss in open grazing treatment was found to be 26Á6 times more than of that occurred in cultivated plots.
