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 static water level (I = 0.063, p = 0.0336), whereas discharge exhibits no significant spatial autocorrelation (I = −0.032, p = 0.7847). Hierarchical agglomerative clustering identifies two complementary organizational scales: a functional hydrogeological classification into three clusters (k = 3, s = 0.3045), corresponding to regolith reservoirs, hydrodynamically constrained media, and high-yielding structural fractures, and a broader macro-spatial regionalization into two clusters (k = 2, s = 0.4978). This scale-dependent organization highlights t...

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 Weighting (IDW) interpolation. The results demonstrated a seasonally differentiated distribution of droughts. While drought dominates the pre-wet season; a distinct wet phase occurs during the peak rainy months of July and August. In contrast, the post-wet season, exhibits fluctuating wet and drought periods. RAI values reflect high inter-seasonal variability, showing that rainfall is concentrated into only a few months. This exposes different regions of Burkina Faso to greater risks of drought. This concentration increases drought risk across vari...

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 ) but empirical fit on 20 BRVM assets unambiguously yields ξ=1/(p−1) . Using independent numerical estimation of p (via the SBA method) and ξ (via GPD), we find excellent agreement. Results show strong heterogeneity across sectors, with agriculture exhibiting the heaviest tails (ξ up to 0.56) and violation of mean reversion. A stress-testing grid is proposed for regulators.

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 both reflects and shapes broader empowerment dynamics. This study, based on data from the Performance Monitoring for Action (PMA) research platform in Burkina Faso, aims to assess the validity of a multidimensional measure of agency specifically adapted to reproductive health in the Burkinabe context. This measure consists of two key dimensions: motivation—the ability to define reproductive goals—and self-efficacy—the ability to act on them. It explores women's decision-making autonomy in two key areas of reproductive health: family planning and sexual...

Aims: To assess the hygiene practices, socio-economic determinants, and microbiological quality of Koura koura skewers sold in three cities of Burkina Faso, and to examine the relationships among vendor knowledge, socio-economic status, observed hygiene practices, and product contamination. Study Design: A cross-sectional study combining a vendor questionnaire survey and direct observation of hygiene practices with microbiological analysis of product samples. Place and Duration of Study: The study was conducted in three cities of Burkina Faso: Kaya and Korsimoro (Kuilsé region, in the north-central part of the country) and Ziniaré (Oubri region, in the central part of the country), between August and September 2025. Methodology: A structured questionnaire and observation grid were administered to 78 Koura koura skewer vendors (36 in Kaya, 18 in Korsimoro, and 24 in Ziniaré) using a co...

Abstract—The convergence of software-defined networking and the Internet of Things widens the attack surface of connected networks and calls for defenses able to detect attacks at the controller's vantage point and to block them there. Earlier work compared deep architectures for denial-of-service attack detection and opened two perspectives: extension to the multiclass setting and integration into an operational intrusion detection and prevention system acting in real time. This article takes up these perspectives in an SDN-IoT context. On ASEADOS-SDN-IoT, a recent dataset that synchronizes device traffic with controller telemetry, we evaluate a deep detector organized as a two-stage cascade covering five traffic classes, comparing six architectures at each stage. The hybrid CNN-BiLSTM network offers the best trade-off, and the cascade outperforms a direct multiclass classifier ev...

Abstract Objective: To describe the epidemiologic characteristics and clinical presenta tion of Primary liver cancer (PLC) at Tengandogo University Hospital (Centre Hospitalier Universitaire of Tengandogo, CHU-T) in Ouagadougou, Burkina Faso. Methods: This was a retrospective observational study conducted at CHU T, from 1 May 2013 to September 30, 2023. All patients seen for PLC in out patient consultation or inpatient hospitalization were included. Results: One hundred and twenty-four (124) cases of PLC were included, representing an annual average of 11.8 cases. The mean age was 49.6 years, with the age group of 40 - 50 years most commonly represented. The male-to-female sex ratio was 4.2. The majority of patients (56.5%, n = 70) had a WHO performance status score of 3 (patient confined to bed or a wheelchair > 50% of waking hours). Abdominal pain (64.5%, n = 80) an...

Access to clean and affordable cooking energy remains a challenge in developing regions, particularly in sub-Saharan Africa, where traditional biomass fuels are widely used and are associated with environmental and health concerns. Solar cooking provides a renewable alternative; however, the practical application of low-cost cylindrical solar concentrators for cooking under fluctuating tropical weather conditions remains insufficiently evaluated. This study presents the design and experimental performance evaluation of a low-cost, manually tracked cylindrical solar concentrator intended for cooking applications. The concentrator features an aluminium reflector with a 1.2 m² aperture area and a geometric concentration ratio of 12. Experimental tests conducted during the rainy season under fluctuating solar irradiance assessed the system's thermal performance using water and cottonseed oil...

Introduction. Les plaies abdominales par arme à feu (PAAF) constituent une urgence chirurgicale vitale, particulièrement dans les zones de conflit armé où les ressources médicales sont limitées. Au Burkina Faso, l'insécurité croissante expose les populations civiles et militaires à ces traumatismes sévères, dont la prise en charge reste mal documentée. Cette étude décrit les aspects épidémiologiques, diagnostiques, thérapeutiques et pronostiques des PAAF au Centre Hospitalier Régional Universitaire de Fada N'Gourma (CHRU-FG). Méthodes. Nous avons mené une étude rétrospective descriptive et analytique du 25 décembre 2024 au 24 décembre 2025, incluant tous les patients hospitalisés pour PAAF. Les données ont été extraites des dossiers médicaux et analysées avec SPSS 25. Les facteurs associés à la mortalité ont été identifiés par le test exact de Fisher et le test de Mann-...

Avec l’essor des Technologies de l’information et la communication (TIC), l’agriculture de précision constitue une opportunité stratégique pour améliorer les rendements agricoles au Burkina Faso. L’objectif de cette étude est d’analyser les contraintes actuelles limitant l’adoption de l’agriculture de précision au Burkina Faso. Pour ce faire, des données qualitatives ont été collectées à travers des entretiens semi-directifs auprès des principaux acteurs du secteur dont sept (07) opérateurs privés, 13 directions régionales et 2 directions générales en charge de l’agriculture. Les résultats montrent que l’adoption de la technologie reste limitée par des facteurs tels que le coût élevé de la technologie, un manque de compétences techniques et des contraintes réglementaires. Malgré ces contraintes, l’Etat et ses partenaires techniques et financiers, les instituts de recherche et le secteur...
