Agronomic performance of Bambara groundnut genotypes [Vigna subterranea (L.) Verdc] under organic fertilization in the Sudano Sahelian zone of Burkina Faso
Adjima Ouoba, Ali Lardia Bougma, Dominique Nikiema, Diane J. Kambou, Mahamadi Hamed Ouedraogo, Nerbéwendé Sawadogo, Mahama Ouedraogo
In Burkina Faso, Bambara groundnut yields remain low in smallholder agrosystems, partly due to poor soil fertility and limited use of adapted genotypes. Integrating organic fertilization with the selection of high-performing genotypes may enhance crop productivity under Sudano-Sahelian conditions. This study evaluated the agronomic performance(...)

Climate change, land-use intensification, and agroforestry management are key drivers of soil organic carbon (SOC) dynamics in Sub-Saharan Africa, yet their combined effects remain poorly understood. Using a hierarchical space-for-time substitution approach, we analysed 1,440 soil samples from protected areas, fallows, and croplands across fou(...)

Lompo Yemboado Dieudonné, Kabore Gueswende Xavier François, Yameogo Relwende Barnabé, Ouedraogo Mahamoudou, Traoré Solo
Le syndrome de perfusion artérielle inversée (Twin Reversed Arterial Perfusion Syndrome – TRAP) est une forme grave de complication très ??? des jumeaux monochorial perfuseur-perfusé. Nous rapportons ce cas de jumeaux découverts au cours du travail d’accouchement des jumeaux nés par voie basse d’une patiente de 21 ans qui n’a réalisé aucune éc(...)

Contribution of Electrical Resistivity Tomography to the Characterization of Aquifers in a Sub-Outcrop Context in the Basement Zone of the Oubri Region (Burkina Faso)
Hoboubé Nicole Abotsi, Julien Nikiema, Mahama Sawadogo
Population growth and climate change are putting drinking water resources at risk, making groundwater a key solution to these challenges. In Burkina Faso, more than 80% of the geology consists of crystalline bedrock, which necessitates the search for bedrock aquifers for water supply. The complexity of these aquifers has led to numerous unsucc(...)

Introduction: Hepatitis B virus (HBV) infection remains a major public health problem despite the introduction of a universal HBV vaccination several years ago. Thus, the high endemicity, observed especially in developing countries, particularly in Togo, underlines the urgent need for further research into the mechanisms explaining the diversi(...)

Towards Innovative Intelligent Cyber Defense Approach Based on Deceptive Security and Deep Learning Techniques
Saoudata Bougma, Didier Bassole, Pegdwindé Justin kouraogo, Sidwendluian Romaric Nana
In this paper, we propose a critical analysis of recent advances in cybersecurity, particularly the application of deep learning, cyber threat intelligence, and deceptive security. Building on this analysis, we introduce an integrated and innovative approach that combines the collection of attacker traces through deception systems (honeypots)(...)

Geospatial Modeling and Hierarchical Clustering of Hydrogeological Borehole Parameters: Application to the Centre-Ouest Area, Burkina Faso
Fabrice Ouoba, Vini Yves Bernadin Loyara, Hay Yoba Talkibing, Diakarya Barro
This study presents an integrated geostatistical and multivariate clustering framework to characterize hydrogeological variability across 261 boreholes in the crystalline basement aquifers of Burkina Faso. Spatial autocorrelation analysis based on Moran’s I indicates significant spatial dependence for borehole depth (I = 0.088, p = 0.0059) and(...)

Meteorological drought trends in Burkina Faso (1991–2023): A monthly and seasonal rainfall anomaly index analysis
Joseph Yaméogo, Songanaba Rouamba, Suzanne Koala
This article analyzes monthly and seasonal spatial trends in drought within Burkina Faso using the Rainfall Anomaly Index (RAI). Rainfall data from the Burkina National Meteorological Agency (1991–2023) were processed using the R package ‘precinctcon’ and hydroTSM. Trends were then evaluated using Spearman’s Rho (SR) tests and Inverse Distance(...)

Assessment of ethnobotanical knowledge about Flemingia faginea (Guill. & Perr.) Baker around the protected areas of Bontioli and Tiogo (Burkina Faso)
Raymond Nana, Hugues Roméo Bazié, Assan Gnoumou
Background: Flemingia faginea is a riparian species restricted to riverbanks and currently facing population decline. Its limited natural regeneration results from the combined effects of climate variability and anthropogenic disturbances. Ethnobotanical surveys serve as a vital bridge between scientific and local knowledge, supporting sustain(...)

Boundary Layers and Heavy Tails in Finance
Mamadou Birba, Moussa Bagayogo, Vini Yves Bernadin Loyara
This paper proposes a unified framework combining Extreme Value Theory (EVT) and nonlinear partial differential equations to model financial returns on the BRVM. We conjecture a link between the EVT tail index ξ and the p-Laplacian exponent p: ξ=1/(p−1) . The conjecture is motivated by a heuristic boundary layer analysis (which suggests ξ=1/p(...)

Reproductive Agency: Validation of a Measure for Women's Autonomy in Family Planning and Sexual Intercourse in Burkina Faso
Fiacre Bazié, Yentéma Onadja, Abdramane B. Soura, Meagan E. Byrne & Fernand B. Bationo
The links between women's empowerment and their reproductive health remain complex due to persistent challenges in defining empowerment and its various components, as well as the factors shaping it in different contexts. These difficulties also stem from the inability to conceptualize reproductive empowerment as an independent process that bot(...)

Agronomic Performance and AMMI Stability Analysis of Solenostemon rotundifolius Response to Key Climatic Parameters
Ignace Tondé, Alphonse Tégawendé Sawadogo, Zakaria Kiébré and Romaric Kiswendsida Nanéma
Solenostemon rotundifolius, an indigenous West African tuber crop known as “fabirama”, faces production challenges due to climate variability. Farmers lack knowledge regarding genotype-by-planting date interactions, which limits yield and crop cycle optimization. Therefore, this study evaluated the stability of yield and cycle, two critical ag(...)
