Effects of Agroecological Practices (Za¨ı 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(...)

Hourly Soil Temperature Variability and Estimation at Multiple Depths from Meteorological Data Using Multiple Linear Regression in a Tropical Semi-Arid Region of Burkina Faso
François Dabilgou, Soumaila Gandema, Marcel Bawindsom Kébré, Zamantakonè Guillaume Ki, Zakarie Koalaga
Accurate estimation of soil temperature is essential for understanding land–atmosphere interactions and supporting agricultural management in semi-arid regions. This study focuses on the analysis of hourly soil temperature variability and the performance of Multiple Linear Regression (MLR) models at depths of 10, 20, 30, and 40 cm in a tropica(...)

Agrochemical lock-in and land tenure insecurity: interacting barriers to agroecological transition in Burkina Faso’s family farming systems
Adama Zoungrana,· Patrice Bayipoukouba Akiam, · Yama Togola,· André Babou Bationo,· Salifou Traoré, · Marjolein Visser, · Charles De Cannière
Agroecological transition is essential for achieving food security in sub-Saharan Africa. However, socio-economic and political
barriers to this transition remain largely understudied, particularly in the context of land tenure disparities. This study aims
to assess the influence of land tenure dynamics on current agricultural practices and(...)
