As compared to natural forest ecosystems, soils under agroecosystems are more subjected to changes in physical and biochemical attributes. But, tree species that are retained and/or planted on these agroecosystems replenish soil fertility through the influence of leaves litterfall quantity and quality. Tree species-related differences in the quantity and seasonality of leaves litterfall and the associated

Modeling the potential impacts of automated vehicles on pollutant emissions under different scenarios of a test track Environ. Syst. Res. Pub Date : 2022-12-12 Biramo, Zelalem Birhanu, Mekonnen, Anteneh Afework
One of the significant sources of air pollution and greenhouse gas emissions is the road transportation sector. These emissions are worsened by driving behaviors and network conditions. It is common knowledge that experienced and inexperienced drivers behave differently when operating vehicles. Given the same vehicle in a different timeframe, the drivers’ reactions to similar situations vary, which

Spatio-temporal variability and trends of hydroclimatic variables at Zarima Sub-Basin North Western Ethiopia Environ. Syst. Res. Pub Date : 2022-12-02 Zegeye, Meaza Kassahun, Bekitie, Kassahun Ture, Hailu, Dessie Nedaw
Globally, hydroclimatic variables have been changed due to human activities and have an impact on agricultural production and water resource management. This study investigated the spatio-temporal variability of hydroclimatic variables in Zarima subbasin using rainfall and temperature data from 1984 to 2018 and stream flow data from 1990 to 2014. The data were analyzed using the coefficient of variation

The impact of rainfall variability and crop production on vertisols in the central highlands of Ethiopia Environ. Syst. Res. Pub Date : 2022-12-02 Bedane, Hailu Regassa, Beketie, Kassahun Ture, Fantahun, Eyasu Elias, Feyisa, Gudina Legese, Anose, Fikre Abiko
Understanding the yearly, seasonal, monthly, and weekly rainfall variability is crucial for improved agricultural practice in Ethiopia, where agriculture depends on rainfall. In particular, knowledge of rainfall onset, withdrawal, amount, distribution, and the length of the crop growing period would protect farmers from crop damage due to climatic anomalies. This study collected and described 39 years

Synthesis of eco-friendly ZnO-based heterophotocatalysts with enhanced properties under visible light in the degradation of organic pollutants Environ. Syst. Res. Pub Date : 2022-11-20 Batchamen Mougnol, Jean Bedel, Waanders, Frans, Ntwampe, Seteno Karabo Obed, Fosso-Kankeu, Elvis, Al Alili, Ali Rashed
Heterogeneous photocatalysts have been widely used for the removal of various organic pollutants from wastewater. The main challenge so far resides in the sustainability of the process, with regard to the synthesis and the application under visible light. In this study the precipitated materials from the Moringa oleifera seed (MO), groundnut shells (GS) and apatite (A) agrowastes were functionalized

Analysis of temperature variability utilising Mann–Kendall and Sen's slope estimator tests in the Accra and Kumasi Metropolises in Ghana Environ. Syst. Res. Pub Date : 2022-11-12 Frimpong, Bernard Fosu, Koranteng, Addo, Molkenthin, Frank
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 Detection

Rural household perception and adaptation strategies to climate change and variability: in the case of Libo-kemkem Woreda, Ethiopia Environ. Syst. Res. Pub Date : 2022-11-09 Megabia, Tesfa Tilahun, Amare, Zerihun Yohannes, Asmare, Abraham M.
Studying Libo-kemkem Woreda households’ perceptions and responses to climate change and variability was the primary focus of this study. A cross-sectional and primary data collection method was used in this study to address its main objective. Based on stratified and straightforward random selection methods, 216 rural households were selected for the study. Through the household survey, data was collected
