Analysis of evaporation-induced water losses from rectangular and cylindrical rainwater harvesting basins (non-truncated and frustum) in a hot tropical climate (Burkina Faso)
Mariatou Zon; Soumaïla Gandema; Marcel Bawindsom Kébré; Wenceslas Somda; Zacharie Koalaga
This study models and simulates rainwater harvesting basins in the Sahelian zone to quantify evaporation-driven water losses and assess implications for design and water-resource management. Four basin geometries are evaluated—parallelepiped, prismoid (rectangular frustum), truncated cone (cylindrical frustum), and perfect cylinder—using a uni(...)

Assessing flood risks in Burkina Faso’s urban centers using bias-corrected projected extreme precipitation data from CMIP6 models
Songuiyamina Bienvenue SANDAMBA; Wenceslas SOMDA; Marcel Bawindsom KEBRE; Antoine BERE
In the context of escalating climate change impacts, particularly intensified extreme precipitation and flood risks in West Africa, this study addresses Burkina Faso’s vulnerability to hydroclimatic extremes. Focusing on four representative cities Ouagadougou, Bobo-Dioulasso, Fada-N’Gourma and Ouahigouya across three climatic zones, the resear(...)

CMIP6 projections of agroclimatic characteristics across the climatic zones of Burkina Faso, West Africa
Mazo Dabré; Moussa Waongo; Marcel Bawindsom Kébré; Jacques Ulrich Diasso
Sahelian countries are among the most vulnerable regions to climate change–related natural hazards, and Burkina Faso, located in the Sahelian zone of West Africa, is particularly exposed. This study analyzes a set of precipitation-based climate indices (RX1day, RX5day, SDII, CWD, R10mm, R20mm, R95pTOT, R99pTOT) and assesses the impact of clima(...)

Fish diversity and environmental drivers in two communities-dependent reservoirs in the semi-arid zone (Burkina Faso)
Idrissa Ouedraogo, Komandan Mano, Victor Bance, Adama Oueda
Small reservoirs are vital to local communities, providing food resources such as fish and other ecosystem services. However, the lack of data on fish diversity, dynamics, and structure in these reservoirs limits decision-makers' ability to formulate effective management strategies. This study aimed to determine the taxonomic composition of fi(...)

Effects of Agroecological Practices (Zaï and Stone-Rows) on Soil Fertility and Sorghum Yield in Response to Effects of Climate Change to Achieve Food Security
Aboubacar Coulibaly; Fidele Zongo; Cheick Oumar Zoure; Pascal Bazongo; Issoufou Ouedraogo; Edmond Hien and Mikael Motellica
The adoption of sustainable agricultural practices can slow down the degradation of arable land and enhance agricultural productivity, particularly land in the context of climate change. This study aimed to evaluate the effect of agroecological practices, specifically zaï and stone-rows (SR), on soil fertility and sorghum (kapelga variety) pro(...)

Comparative Analysis of Machine Learning and Deep Learning Approaches for Hourly Soil Temperature Estimation At Multiple Depths from Meteorological Data in A Semi-Arid Region of Burkina Faso
François Dabilgou, Marcel Bawindsom Kébré, Soumaila Gandema, Zacharie Koalaga
Accurate estimation of soil temperature is essential for understanding land–atmosphere interactions and managing agricultural systems, par-particularly in semi-arid regions. This study evaluates and compares the performance of multiple modeling approaches: machine learning (Random Forest, XGBoost, LightGBM, SVR, GPR, Decision Tree), and deep(...)

Mercury transfer and transformation from mine soil to river sediments: the potential role of amorphous iron oxides in methylation processes in southern Burkina Faso
DABRE Djamilatou, GUERON Stéphane, MAIGA Ynoussa, JELAVIC S., CAMPILLO S., Fin J., SENTENAC S., BRUNEEL Odile, OUEDRAOGO Ousséni, MASON Robert
Since the early 2000s, artisanal and small-scale gold mining (ASGM) has rapidly expanded in Burkina Faso. Mercury (Hg) is widely used to extract gold and its release through burning amalgams has led to soil contamination near mining sites. However, the fate and speciation of Hg in soils remains poorly understood, especially the reactivity or m(...)
