Land salinization is threatened with secondary salinization recently because of unreasonable exploitation of natural resources and global change. However, previous assessments cannot obtain comprehensive and spatial explicit statistics and impede to develop ecologically sound policies for government. This study tries to confront these difficulties and identify key anthropogenic determinants, th...

The current applications of geographic information systems (GIS) applications to non-point-source pollution modeling for agricultural area are reviewed with respect to the requirements for GIS, the hydrological/water quality modeling processes, and integration between GIS and Non-Point-Source Pollution (NPSP) models. Some necessary considerations for future studies are also discussed by summari...

Soil loss resulting from various land management practices in traditional rubber-growing areas of Sri Lanka has been a major issue concern and one the factors responsible for declining rubber productivity. There is no or limited information on spatial variability soil lands Lanka's growing areas. This constraint had significant impact effective conservation lands. study focuses assessing smallh...

Atmospheric pollution due to the use of agricultural pesticide is a major concern today, regarding both public health, sustainable agriculture and ecosystems quality monitoring. This work aims to model pesticide atmospheric dispersion and to propose an useful air pollution prediction tool, using fluid mechanics equations and open-source GIS programming capabilities. This work focuses on pestici...

Soil loss is one of the most important causes land degradation. It an inevitable environmental and socio-economic problem that exists in many physiographic regions world, which, besides other impacts, has a direct bearing on agricultural productivity. A reliable estimate soil critical for designing implementing any mitigation measures. We applied widely used Revised Universal Loss Equation (RUS...

Abstract The erosion of soil is one the most difficult and ongoing problems caused by deforestation, improper cultivation, uncontrolled grazing, other anthropogenic activities. As a result, assessing level quantity essential for agricultural productivity natural resource management. Thus, goal this study was to quantify loss rates identify hotspot locations in Tashat watershed, Abay basin, Ethi...

An approach is proposed in the present study to estimate soil erosion data-scarce Kokcha subbasin Afghanistan. The Revised Universal Soil Loss Equation (RUSLE) model used erosion. satellite-based data are obtain RUSLE factors. results show that slight (71.34%) and moderate (25.46%) dominated basin. In contrast, high (0.01%) insignificant area. highest amount of observed Rangeland (52.2%) follow...
