A spatial decision support system (SDSS) based on multi-criteria and multi-objective decision analysis is applied in a case study in Ethiopia to reduce soil erosion on the basis of reallocation of crops according to their capacity to protect the soil. The case study is carried out in the Adwa district. The SDSS has been implemented using the widespread GIS software IDRISI 32 (release 2) and wit...

This study modeled the urban growth in the Greater Cairo Region (GCR), one of the fastest growing mega cities in the world, using remote sensing data and ancillary data. Three land use land cover (LULC) maps (1984, 2003 and 2014) were produced from satellite images by using Support Vector Machines (SVM). Then, land cover changes were detected by applying a high level mapping technique that comb...

Erosion is one of themost important natural hazard phenomena in theworld, and it poses a significant threat to Turkey in terms of land degredation and desertification. To cope with this problem, we must determine which areas are erosion-prone. Many studies have been carried out and different models and methods have been used to this end. In this study, we used a logistic regression to prepare a...

It is important to know how the results from a land change model vary based on both the pixel resolution of the maps and the precision of the independent variables because subjective decisions or default values frequently determine these two factors. This paper presents an approach to measure the variation in model accuracy that is triggered by alteration of the pixel resolution and the precisi...

Land use and land cover change are among the drivers of environmental change. The Suluh River Basin’s modeled in this study using a modeler. To accomplish goals study, Landsat images ancillary data sources were utilized. In eCognition Developer 9.2 software, nearest neighbor fuzzy classification was used to classify images. With IDRISI Selva 17.3 detection modeling carried out. Both qualitative...

Urbanization is a pressing issue of concern especially in Africa where it expected to continue and increasingly, threaten the efficiency natural carbon sinks sustainability cities. This paper assessed diversity storage trees Zaria metropolis, North-western Nigeria through fieldwork allometric equations. A total 200 assessment plots were randomly generated using Idrisi Terrset software. Quadrats...

Land Use Cover Change (LULCC) and urban growth prediction analysis are two of the best methods that can help decision-makers for better sustainable management planning socioeconomic development in countries. In present paper, land use was analyzed predicted all districts El Baha region (Kingdom Saudi Arabia) based on high-resolution Landsat, 5, 7, 8 satellite imagery during period study between...

The Three Gorge Project (TGP) of China necessitates the resettlement of over 1 million population (mostly farmers) to more rugged and isolated areas than their original settlements. Soil erosion is a serious environmental and production problem in this area. To decrease the risk on environmental impacts, there is an increasing demand for sound, and readily applicable techniques for soil conserv...
