Aims: The overall objective of this study was to assess the effect of different densities of tree dominated by V. paradoxa and dendrometric parameters on the selected soil physical properties. Study Design: This study was conducted in the municipality of Sapone (12.03´N, 1.43´W) located 30 km south of Ouagadougou, Burkina Faso. Place and Duration of Study: The experimental design was made of 20 plots randomly. The studied factor was the tree density (D) in each of our plots, with 5 tree density levels being designed. The first density class (D1) was 0 trees/ha, i.e. 0 tree in the plot, the second was 16 trees/ha, i.e. 4 trees in the plot (D2), the third was 28 trees/ha, i.e. 7 trees in the plot (D3), the fourth was 36 trees/ha i.e. 9 trees in the plot (D4), and finally the fifth was 48 trees/ha i.e. 12 trees in the plot (D5). Each density class is repeated four times. In each plot, 9...

Sweetpotato is a key crop for global food security, particularly in Burkina Faso, where its productivity is increasingly threatened by viral diseases, especially those caused by CRESS-DNA viruses. However, the diversity of these viruses in Burkina Faso remains poorly characterized due to limitations of conventional diagnostic approaches. In this study, nanopore sequencing was used to investigate the diversity of CRESS-DNA viruses infecting sweetpotato in Burkina Faso. Ninety-eight symptomatic dried leaf samples from a previously established biobank were selected and analyzed. Total DNA was extracted, enriched using rolling circle amplification (RCA), and sequenced using the MinION Mk1C platform. In parallel, RNA viruses were also investigated using nanopore sequencing. RCA successfully amplified 53 of the 98 samples, from which 28 complete and 25 partial CRESS-DNA virus genomes were reco...

Malaria remains a significant global health challenge that affects more than 200 million people each year and disproportionately burdens regions with limited resources. Precise and timely diagnosis is critical for effective treatment and control. Traditional diagnostic approaches, including microscopy and rapid diagnostic tests (RDTs), encounter significant limitations such as reliance on skilled personnel, high costs and slow processing times. Advances in deep learning (DL) have demonstrated remarkable potential. They achieve diagnostic accuracies of up to 97% in automated malaria detection by employing convolutional neural networks (CNNs) and similar architectures to analyze blood smear images. This survey comprehensively reviews deep learning approaches for malaria detection and focuses on datasets, architectures and performance metrics. Publicly available datasets, such as the NIH an...

In Burkina Faso, livelihoods rely strongly on the primary sector such as livestock farming. Owing to their high reproductive potential, rapid growth, and relatively low production costs, rabbit farming appeared increasingly as a sustainable source of income and animal protein. However, rabbits are frequently affected by parasitic infections, which can impede their productivity. In Burkina Faso, data on the parasite fauna associated with rabbit remains scarce. The present study aimed to assess the diversity of parasites infecting domestic rabbits in Ouagadougou and its surrounding peri-urban areas. From June to October 2025, 30 domestic rabbits were examined for parasite collection. A total of 438 individuals parasites were collected. Two species of gastrointestinal Nematoda (Passalurus ambiguruus, Passalurus sp.) and one species of ectoparasitic Achnida (Rhipicephalus sp.) were identifie...

Introduction: Hibiscus sabdariffa L. is an economically important and widely adopted crop in Burkina Faso. Yet its production is constrained by the lack of improved, locally adapted varieties. This study used a participatory variety selection approach to identify preferred landraces and selection criteria across two agroecological zones: Sudanian and Sudano-Sahelian. Methods: The evaluation of landraces/accessions was carried out using an ordinal rating system, assigning scores ranging from 9 (most preferred accession), through 7 (very interesting), 5 (moderately interesting), 3 (less interesting), to 1 (least interesting). Landraces considered undesirable were specifically evaluated using negative scores of −5, −3, and −1, reflecting the degree of rejection expressed by the participants. Results: Participatory selection involved 126 stakeholders (75.4% women), including producers...

This paper investigates the application of the Laplace-SBA method to a nonlinear Burgers-type equation with a fractional time derivative in the sense of Caputo. Such equations, which incorporate memory effects and nonlocal behavior, are increasingly used to model

Contexte : Lorsque l’on considère les maladies non transmissibles (MNT), les cancers du col de l’utérus et du sein figurent parmi les principales causes de morbidité et de mortalité féminine au Burkina Faso. Bien que le dépistage précoce constitue une stratégie efficace pour améliorer la survie et la qualité de vie des femmes, les taux de recours y demeurent faibles. Cette étude explore les facteurs associés au dépistage du cancer du col de l’utérus et du sein chez les femmes burkinabè âgées de 15 à 49 ans.Données et méthodes:Cette recherche a combiné une analyse descriptive des taux de dépistage et une régression logistique binaire pour identifier les facteurs influençant le recours au dépistage des deux types de cancer à partir des données de l’enquête démographique et de santé (EDS) réalisée en 2021. L’analyse a porté sur un échantillon de 17659 femmes â...

Energy poverty remains a critical development challenge in low- and middle-income countries, central to achieving Sustainable Development Goal 7 (SDG7). This study investigates the causal impact of deforestation on energy poverty, focusing on two key dimensions: access to electricity and access to clean cooking fuels. Using a panel of 95 developing countries from 2000 to 2023, we employ robust econometric techniques, including ordinary least squares (OLS), two-stage least squares (2SLS), and smoothed instrumental variable quantile regression (SIVQR), to account for endogeneity and distributional heterogeneity. The results consistently show that deforestation significantly worsens energy poverty, particularly in more deprived contexts, by reducing access to clean fuels and electricity. These findings remain robust across alternative deforestation measures and model specifications. Further...

Les enceintes et structures en pierre sont les principaux vestiges archéologiques connus dans l’espace géoculturel appelé abusivement ‘pays lobi’ au Burkina Faso, Afrique occidentale. Depuis les premières publications à leur sujet au début du vingtième siècle, leur architecture a été l’aspect matériel le plus traité. Cette focalisation sur les aspects architecturaux se justifierait par leur caractère atypique pour la région d’une part et leur facilité d’accès à travers les affleurements de murs en surface, d’autre part. En revanche, le mobilier archéologique, notamment céramique a été négligé, même si plusieurs auteurs y font référence. À l’avènement des fouilles archéologiques au début des années 2000, la production céramique s’est avérée majoritaire dans les corpus du mobilier mis au jour lors des différentes investigations. Au regard du potentiel de la céramique pour appréhender fa...

Le taux de déperdition des participants dans une cohorte prospective est une préoccupation majeure pour les investigateurs, compte tenu de son impact sur la validité interne des enquêtes. Notre étude avait pour objectif d’évaluer l’effet des appels téléphoniques sur les taux de suivi d’une cohorte de nourrissons au Burkina Faso. La cohorte du Projet CHAIN-BURKINA FASO était constituée de nourrissons âgés de 2 à 23 mois, hospitalisés pour morbidité aiguë et suivis pendant 6 mois après l’hospitalisation respectivement à J45, J90 et J180. Une régression binomiale avec calcul de risque relatif (RR) a permis d’estimer l’effet des appels téléphoniques sur l’effectivité de la visite de suivi planifiée. Au total, 415 enfants hospitalisés et sortis vivants ont été inclus dans les analyses. Les taux de suivi étaient respectivement de 93,6% (IC95%= [92,6 - 94,4]) à J45 ; 89,1% (IC95%=...
