One of the consequences climate change is increasing rainfall intensity and frequency leading to flooding. Lately, some major cities in West Africa have been experiencing high flooding due extreme rainfall. This study investigated temporal trends flash flood events Bamako, Mali for period 1982–2019. Rainfall observation data from both Meteorological Agency Climate Hazards Group Infrared Precipitation, ground information' collected Civil protection service were used this study. Five indices...
In this paper, ensemble-based machine learning models with gradient boosting and random forest are proposed for predicting the power production from six different solar PV systems. The based on three year’s performance of a 1.2 MW grid-integrated photo-voltaic (PV) plant. After cleaning data errors outliers, model features were chosen basis principal component analysis. Accuracies developed tested compared other supervised algorithms, such as k-nearest neighbour support vector machines....
Considering the high vulnerability of Northern Tanzania to climate change, an in-depth assessment at local scale is required urgently formulate sustainable adaptations measures. Therefore, this study analyzed future (2021-2050) changes in rainfall and temperature under representative concentration pathways (RCP4.5 RCP8.5) for watersheds surrounding Ngorongoro Conservation Area (NCA) a spatio-temporal relative observed historical (1982-2011) period. The change analysis was performed monthly...
Abstract Water security has been a major challenge in the semi-arid area of West Africa including Northern Ghana, where climate change is projected to increase if appropriate measures are not taken. This study assessed rainfall and temperature projections its impact on water resources Vea catchment using an ensemble mean four bias-corrected Regional Climate Models Statistical Downscaling Model-Decision Centric (SDSM-DC) simulations. The simulations was used as input already calibrated...
This study investigated the changes in climate and spatiotemporal variations extreme indices of Dano catchment Burkina Faso using historical data for period 1981–2010 projected 2020–2049. Rainfall temperature simulations from two RCMs under Representative Concentration Pathways (RCP 4.5 RCP 8.5) involved CORDEX-Africa project were used this study. The found that change signal future based on ensemble mean indicates a decrease annual rainfall by 25.2% 25.6% RCP4.5 RCP8.5 respectively. A clear...
Climate change is projected to negatively affect water security which already a challenge in many areas of Ghana including the Tano river basin (TRB). This study assessed projections rainfall and temperature its impact on streamflow actual evapotranspiration (ET) TRB for 2021-2050 relative period 1986-2015. The assessment focused how climate under Representative Concentration Pathways (RCP 4.5 RCP8.5) based an ensemble mean two regional models (RCMs) would ET using Soil Water Assessment Tool...
Abstract Understanding rainwater dispersion in a spatiotemporal context is invaluable toward resourceful water management and food-secure society. This study, therefore, assessed the variations rainfall at scale Oti River Basin of West Africa for observed (1981–2010) future periods (2021–2050) under representative concentration pathways (RCPs) 4.5 8.5 emission scenarios. Rainfall data from meteorological stations Climate Hazards Group Infrared Precipitation with Stations (CHIRPS) were used....
Groundwater account for about 60 to 80% of water supply the population Tanzania's semi-arid regions domestic and agriculture uses. Despite importance groundwater resource in areas, limited information exists on recharge amount potential zones Tanzania context climate change which could result unsustainable withdrawals. This study aimed estimate impact identify Lake Manyara catchment using Water Energy Transfer between Soil, Plants Atmosphere under quasi-steady State (WetSpass) model. The...
Climate change has become a global issue, not only because it affects the intensity and frequency of rainfall but also impacts economic development regions whose economies heavily rely on rainfall, such as West African region. Hence, need for this study, which is aimed at understanding how may in future over Sahel, Savannah, coastal zones Volta River Basin (VRB). The trends changes between 2021–2050 1985–2014 under Shared Socioeconomic Pathway (SSP2-4.5 SSP5-8.5) scenarios were analyzed...
Abstract This study examined the temperature variations in West Africa's Volta River Basin (VRB) from 2021 to 2050 comparison historical period (1985–2014) under two Shared Socioeconomic Pathway Scenarios (SSP2-4.5 and SSP5-8.5). Datasets three Global Climate Models (GCMs) of sixth Coupled Model Intercomparison Project (CMIP6) were used. The GCMs their ensemble evaluated on a monthly scale. used mean analyse changes annual over Sahel, Savannah, Guinea Coast, entire basin. results demonstrate...
Coronavirus disease (COVID-19) has impacted every aspect of human existence in a variety ways. However, depending on how we interpret the impact pandemic, may either despair or embrace challenges with hope. Several empirical findings and expert opinions have highlighted significant negative COVID-19 economy, health wellbeing, education, ecosystem governance around world. Amid all these effects existence, claim that there are some silver linings across several domains such as eco-system...
The lichen biomonitoring technique was used to study trace element atmospheric deposition in the Kassena-Nankana municipality of Ghana. Seven short and medium lived elements (Na, Al, K, Ca, V, Mn Mg) were determined by instrumental Neutron Activation Analysis subjected statistical analysis. Principal component analysis identify characterize different sources pollution. results linear regression correlation test points harmattan mineral dust as main source area.
