The main grassland plain of Nech Sar National Park (NSNP) is a federally managed protected area in Ethiopia designated to protect endemic and endangered species. However, like other national parks in Ethiopia, the park has experienced significant land cover change over the past few decades. Indeed, the livelihoods of local populations in such devel...

Ethiopia has been experiencing an extremely high rate of urban expansion, which increases urban surface temperature. This study aimed to analyse the impact of urban expansion on land surface temperature (LST) using geospatial techniques in the rapidly expanding cities of Addis Ababa and Shaggar city. Landsat TM of 1994, Landsat ETM+ of 20,09, and L...

Soil erosion and sediment yield driven by land use and land cover changes; pose severe threats to ecological sustainability, agricultural productivity, and watershed health. This study evaluates soil erosion and sediment yield in the Dumuga Watershed, Ethiopia, from 1993 to 2023, with a focus on the impact of land use and land cover changes. Utilis...

Assessing the impacts of forest cover change on carbon stock and soil moisture dynamics is critical for understanding environmental degradation and guiding sustainable land management. This study evaluates the effects of forest cover change on carbon stock and soil moisture dynamics in Nensebo Forest from 1993 to 2023 using geospatial techniques. L...

At the global level, landslides are a dreadful hazard that restricts socio-economic and ecological balances. Recent human activities in hilly areas, coupled with geological predispositions, have potentially exacerbated landslide frequency and magnitude. However, the impacts of these factors on landslide occurrences in the upper Blue Nile basin of E...

Soil loss is a substantial peril to agricultural production and economic growth in the global world. Rainfall, slope, and cover management have triggered soil erosion risk in the southwestern hills of Ethiopia, yet little is known about the effects of topography via hydro-geomorphic characters on soil loss in the upper Bilate watershed. Therefore,...

In African nations with complex topographies, alternative rainfall estimation methods such as satellites are crucial. This study is aimed at predicting the spatial and temporal distribution of rainfall in the Lake Tana sub-basin from 1990 to 2020. A satellite-based rainfall estimate of Climate Hazards Group Infrared Precipitation with Station data...

Soil erosion is still a vector of environmental and economic concern affecting most parts of the world, especially in Sub-Saharan African countries. Nevertheless, recent human activities in the hills, coupled with poor conservation measures and practices, could have amplified the rate at which soil is lost in the southwestern highlands of Ethiopia....

The cycle of food insecurity caused by poor water management practices poses major concerns for the sustainability of living balance in Southwestern Ethiopia’s smallholder agricultural areas. The prior study looked at crop land suitability assessments. However, there are still knowledge gaps on irrigation infrastructure sites. As a result, this res...

Urban expansion possesses significant negative impacts on the environment, particularly in forest areas worldwide. This study aimed to analyze urban expansion by using stochastic modeling with the CA-Markov chain and multi-scenario prospects in Mettu area, Ethiopia. The Landsat images of 1986, 2000, and 2021 were used. The results reveal built-up a...

Human-induced actions aggravate forest degradation and result in carbon emissions. Increment of carbon emission raises land surface temperature (LST) and contributes to climate change. The aim of this study was to assess the impacts of forest cover change on carbon stocks, carbon emissions and LST over the period 1992–2022 using geospatial techniqu...

Groundwater is fresh water that is stored in an underground zone, which is less vulnerable to pollution than surface water and communally used for economic, social, and ecological purposes. This study aimed to evaluate groundwater recharge potential by using a geographic information system (GIS) and remote sensing in the Ziway Abijata sub-basin, Ce...

Anthropogenic land use and land cover (LULC) change was the most serious problem in worldwide. This study attempted to investigate spatiotemporal LULC changes in the Upper Anger watershed, Western Ethiopia. In the present study, Landsat TM of 1990, Landsat ETM + of 2003, and Landsat OLI/TIRS of 2020 were used to analyze the LULC change and Normaliz...

Urban green space (UGS) is crucial in providing ecosystem services and optimizing the health of urban residents. This study aimed at identifying suitable sites for UGS development using geospatial techniques in Addis Ababa City. In the present study, an analytical hierarchical process with Geographic Information Systems based multi-criteria evaluat...

Land suitability analysis of Moringa oleifera tree cultivation is important to enhance its product, as the demand forthis tree for medicinal values and food sources is increasing worldwide. Therefore, this study aimed to assess suitableland for Moringa oleifera tree cultivation by using the integration of multi-criteria evaluation with geospatialte...

On a global scale, there is consensus to double food production as a means to address food and nutrition insecurity, yet the capacity of available resources and technologies to gratify the demands of this growing population and the price of agricultural commodities remains uncertain in Sub-Saharan Africa, particularly in Ethiopia. Despite the avail...

Soil erosion is a vector of disturbances to agricultural productivity and economic development in the western highlands of Ethiopia. Yet, tough vegetation cover loss swapped to other land uses could have amplified the soil loss rate at which land cover change preceded, but little is known about their effects on soil loss in the Limu-Seqa watershed....

The northeastern part of Ethiopia, particularly Raya area is a pilgrimage site famed for its antique civilization, archaeological sites, and rural landscapes. Despite existing ecotourism potentials, the area has not been utilized for tourism for millennia. While previous work looked at the availability of natural resources, it did not identify and...

Ethiopia has been experiencing resettlement programs primarily as a response to the tragedy of land degradation. The program, however, resulted in massive deforestation in the resettled sites. This study, therefore, aimed at evaluating the impact of resettlement on the moist evergreen Afromontane forest cover between 2000 and 2018 in the Hawa-Galan...

Rapid conversion of conserved land and cropland to non-agricultural purposes is threatening the ecological areas and dominant agricultural activities that are the main sources of livelihood in urban fringe areas of Addis Ababa City. The combinations of government policy, socioeconomic, demographic dynamics, and biophysical triggers have driven such...

Background The Ethiopian highlands have experienced intense levels of land use dynamics and forest cover transformations over the past few decades. Multiple socio-economic, demographic and bio-physical factors have driven such transformations. Nevertheless, recent expansion of urban settlements and infrastructural development could have accelerated...

Background Temporal change detection of informal settlement was conducted using geographic information system and remote sensing in order to evaluate the land use land cover change (LULCC) in Jimma city, southwestern Ethiopia. We analyzed the LULCC since 1997 using Landsat imagery of 1997, and aerial photography of 2007 and 2017. Qualitative and qu...

Erckel's Francolin Pternistis erckelii and Harwood's Francolin Pternistis harwoodi are pheasant bird species which inhabit in dryland ecosystems along vast areas of the Nile Basin.
