Spatial modeling of erosion hotspots using GIS-RUSLE interface in Omo-Gibe river basin, Southern Ethiopia: implication for soil and water conservation planning
Springer Science and Business Media LLC - - 2020
Rediet Girma, Eshetu Gebre
Abstract Soil degradation due to soil erosion is one of the major environmental threats in developing countries. In resource limited conditions, computing the spatial distribution of soil erosion risk has become an essential and practical mechanism to implement soil conservation measures. This study aimed to assess the spatial distribution of soil loss in Omo-Gibe ...... hiện toàn bộ
Impacts of integrated soil and water conservation programs on vegetation regeneration and productivity as indicator of ecosystem health in Guna-Tana watershed: evidences from satellite imagery
Springer Science and Business Media LLC - Tập 7 - Trang 1-14 - 2018
Getachew Workineh Gella
Northern Ethiopian Highlands, including Guna-Tana watershed, have experienced profound natural resources degradation which are resulted from coupled natural and anthropogenic factors. To mitigate this problem, Ethiopian government has launched various soil and water conservation programs at different watersheds. Overall objective of this study was to analyze impacts of soil and water conservation ...... hiện toàn bộ
Analysis of temperature variability utilising Mann–Kendall and Sen's slope estimator tests in the Accra and Kumasi Metropolises in Ghana
Springer Science and Business Media LLC - Tập 11 - Trang 1-13 - 2022
Bernard Fosu Frimpong, Addo Koranteng, Frank Molkenthin
Temperature variability may have direct and indirect impacts on the environments of the Accra and Kumasi Metropolises in Ghana. This study analysed temperature and trends in temperature in both cities using in-situ measurements from one meteorological station in both cities from 1986 to 2015. The temperature indices were computed using the RClimdex package from the Expert Team on Climate Change De...... hiện toàn bộ
Evaluation of the fate of trace organic compounds using the Level III fugacity model: a case study of Rajbandh open dump site in Khulna City of Bangladesh
Springer Science and Business Media LLC - Tập 12 - Trang 1-13 - 2023
K. M. Pangkaj, I. M. Rafizul, E. Kraft, S. Berner
Khulna is the 3rd largest city corporation in Bangladesh that produces 450 tons of Municipal solid waste (MSW) per day and dumps the waste in the Rajbandh open dump site. The main focus of this study is to determine the fate of chemicals in different environmental media at the Rajbandh open dump site. To accomplish the aim Level III fugacity model was evaluated which is subject to steady-state par...... hiện toàn bộ
Estimation of above-ground biomass in tropical afro-montane forest using Sentinel-2 derived indices
Springer Science and Business Media LLC - Tập 11 Số 1 - 2022
Seid Muhe, Mekuria Argaw
AbstractEmpirical analyses were common methods for forest biomass estimation. Lately, satellite images are popularly used to study different attributes of forest vegetation. Sentinel-2 image provides a significant improvement in spectral coverage, spatial resolution and temporal frequency in assessing forest biomass. This study examined the potential use of multisp...... hiện toàn bộ
Analyzing the impact of environmental variables on the repayment time for solar farms under feed-in tariff
Springer Science and Business Media LLC - Tập 2 - Trang 1-13 - 2013
Bin Lu, Matt Davison
Environmental concerns have promoted the rise of low emissions “green” power technologies such as solar power. In part to make these technologies of economic interest to investors, many green energy policies have been proposed, and a wide variety of green energy developments have been launched which take advantage of these policies. This paper studies the impact of the unpredictable solar insolati...... hiện toàn bộ
Land use/cover spatiotemporal dynamics, driving forces and implications at the Beshillo catchment of the Blue Nile Basin, North Eastern Highlands of Ethiopia
Springer Science and Business Media LLC - Tập 8 - Trang 1-30 - 2019
Asnake Yimam Yesuph, Amare Bantider Dagnew
Land use/cover (LULC) change is a dynamic and complex process that can be caused by many interacting processes ranging from various natural factors to socioeconomic dynamics . It exerts a strong influence on the structure, functions and dynamics of most landscapes. Monitoring and mapping of LULC dynamics are crucial as changes observed reflect the status of the environment and provide input parame...... hiện toàn bộ
A hierarchical analysis of ecosystem classification with implementing in two continental ecoregions
Springer Science and Business Media LLC - Tập 10 - Trang 1-14 - 2021
YanQing Zhang
The ecosystem classification of land (ECL) has been studied for a couple of decades, from the beginning of the perfect organism system “top-down” approach to a reversed “bottom-up” approach by defining a micro-ecological unit. After comparing two cases of the ecosystem classification framework implemented in the different continental ecoregions, the processes were carefully examined and justified....... hiện toàn bộ
Variations in ecosystem service value in response to land use changes in Dhaka and Gazipur Districts of Bangladesh
Springer Science and Business Media LLC - Tập 12 - Trang 1-17 - 2023
Raihan Sorker, Mohammad Wahidur Khan, Alamgir Kabir, Nowshin Nawar
Urban sprawl is a global phenomenon that has resulted in a substantial impact on ecosystem services. This study assessed how land use changes have affected the ecosystem services in Dhaka and Gazipur districts, two important economic centers of Bangladesh. This study analyzed changes in land use categories and their effects on ecosystem services during a thirty-year period, from 1990 to 2020, usin...... hiện toàn bộ
Irrigation suitability evaluation of Zamra irrigation scheme, Abergelle District of Wag-Himra Zone, Amhara Region Ethiopia
Springer Science and Business Media LLC - - 2020
Workat Sebnie, Enyew Adgo, Hailu Kendie
Assessment of suitable lands for irrigation is indispensable to plan and implement different programs in a cost-effective approach for sustainable land use planning and efficient utilization of the land. Hence selecting proper land use based on land suitability evaluation will enhance the productivity per unit area and ensures the sustainable use of land resources. Therefore, the research was desi...... hiện toàn bộ
