Sweet grain sorghum is exploited in Burkina Faso through the consumption of fresh grains early at the doughy stage. To identify, valorise and conserve the genetic diversity of this agricultural resource, SNPs markers are essential tools. The aim of the present study is to assess the genetic diversity of sweet grain sorghum expressed in a linear DNA sequence, and to identify SNPs. To this effect, 50 sweet grain sorghum genotypes were sequenced using DArTseq genotyping platform. The results identified 4610 polymorphic loci with a major allele frequency ≤ 95%. The SNPs identified are made up of 55.23% transitions and 44.77% transversions with an average polymorphism information content of 0.26. The expected heterozygosity value He of 0.18 shows moderate genetic diversity in sweet sorghum in Burkina Faso. The results of the PCoA and AMOVA analyses revealed that genetic diversity is more clos...

Earth, an abundant and ancient material, has been used in construction for millennia. It allows for the creation of diverse dwellings, ranging from simple houses to monumental buildings. However, despite its numerous advantages, earthen construction, particularly through Compressed Earth Blocks (CEBs), is less common than imported materials. These imported materials often fail to meet the demands of climate change, stability, and durability. In Burkina Faso, this phenomenon is particularly pronounced in Ouagadougou, the capital, where earthen architecture is often associated with the image of poor and low-quality housing. Construction represents a strategic sector for economic development, but it remains heavily dependent on expensive and energy-intensive imported materials. Compressed Earth Blocks (CEBs), made from abundant local materials, appear as a sustainable alternative. This stud...

In Burkina Faso, livestock is the second most important sub-sector of agriculture after crop production, contributing significantly to the national GDP and supporting over 80% of households. Live animal trade dominates livestock trading and plays a central role in regional commerce. Livestock markets constitute key hubs for trade, information exchange, and income generation, particularly in Ouagadougou, the country’s main consumption and trading center. To characterize stakeholders, a total of eighty (80) actors were involved in a survey conducted across three livestock markets in Ouagadougou. Most respondents were male (81.20%), reflecting the gender imbalance commonly observed in livestock marketing activities. More than 3/4 of the respondents had over twenty-five years of experience. Livestock sellers represented the dominant group (63.75%), followed by brokers (23.75%) and buyers (12...

Pearl millet (Pennisetum glaucum (L.) R. Br.) is an important crop for populations in arid and semi-arid areas of Africa and India. In Burkina Faso, pearl millet is one of main cereal crops, well known for climate resilient features and nutritional transcendency. However, most cultivated genotypes are landraces, whose productivity is still low. The objective of this study was to characterise the diversity of landraces for morphological traits under field conditions in Burkina Faso. Seventy-two accessions from Burkina Faso (24), India (24) and Togo (24) were evaluated in 2021 and repeated in 2022 at the Gampela station in Burkina Faso. The results revealed a diversity of accessions on grain and collar colours. This variability exists between the accessions on grain shape, ears pubescence and stay green. There is a marked difference between landraces from India landraces, compared to those...

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...

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...

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...

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...

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...

Les études portant sur les violences faites aux enfants sont nécessaires pour accélérer les progrès vers la prévention de cette pratique néfaste. Cette étude examine l’influence des attitudes personnelles des enfants et des normes communautaires perçues concernant la punition verbale et corporelle sur les violences subies par les enfants au Burkina Faso. L’analyse repose sur un échantillon représentatif de 5 504 enfants âgés de 12 à 17 ans, issu d’une enquête nationale réalisée entre mars et juin 2018 par l’Institut Supérieur des Sciences de la Population (ISSP) dans les 13 régions du pays. Les résultats révèlent que l’acceptation de la punition verbale parentale ainsi que la perception par les enfants d’une tolérance communautaire envers la punition corporelle sont positivement associées à une exposition accrue aux violences faites aux enfants durant l’année écoulée. Ces résultats souli...
