Background: The soybean crop plays a crucial role in Burkina Faso’s agricultural sector and contributes significantly to food security and nutrition. The study aimed to evaluate the nutritional composition and antioxidant potential of soybean cultivated in Burkina Faso. Methods: A total of 40 soybean varieties cultivated in 2022 at two sites in Burkina Faso were analyzed using standard methods for six parameters, including total phenolic, total flavonoid, total protein, soluble sugars, phytic acid, DPPH radical scavenging activity and ferric reducing antioxidant power (FRAP). Total phenolic ranged from 1.769 to 2.923 µg GAE/100 mg, total flavonoid from 0.008 to 0.031 µg QE/100 mg, total protein from 1.526 to 2.021 mg/100 mg, soluble sugar from 107.6 to 228.1 µg GE/100 mg and phytic acid concentration from 130.9 to 378.0 µg APE/100 mg. Antioxidant activity varied from 0.786 to 2.28...

Improved variety seeds play an important role in increasing agricultural productivity and production. Unfortunately, one of the major concerns of all those involved in agricultural policy in Burkina Faso is the difficulty of marketing this basic input. This study aims to highlight the opportunities and constraints of marketing certified seed of improved varieties. Semi-structured surveys were conducted among 70 people from three categories of actors: seed producers, seed distributors and food producers, based on random sampling. The results of the surveys revealed the existence of a potential market made up of farmers with areas sown with traditional seeds and a large, little-exploited marketing channel. However, most of the seed produced by seed multipliers and seed companies is purchased by the government and its partners. Marketing difficulties are linked to the high cost of seed, t...

Background: Tacca leontopetaloides is a wild food geophyte used by local communities as famine food, with significant contribution to people subsistence during food crisis events. Local ecological knowledge and use of the species are poorly documented leading to knowledge loss and underutilization of the species. This study explored local knowledge on the species, including ecology, traditional processing technique, use level, barriers to its valuation, and domestication perspective. Methods: A stratified sampling design based on climatic zones and people ethnicity was adopted for ethnobotanical investigations. Semi-structured interviews were conducted from October to December 2022, with 224 local people from five ethnic groups residing in two contrasting climate zones in Burkina Faso. The main information collected included people’s socio-cultural traits, use knowledge and ecology of t...

Monocrystalline and polycrystalline silicon-based modules are commonly used in Burkina Faso, particularly in the city of Koudougou, to generate electricity. However, climatic parameters affect the performance of these modules. It is therefore necessary to conduct a comparative study between polycrystalline and monocrystalline silicon-based photovoltaic solar modules. The objective of this work is therefore to determine the module best suited to the city of Koudougou's climatic context. In this study, climatic parameters such as sunshine and temperature were considered. Thus, based on the mathematical model of a photovoltaic module, a simulation was carried out in the MATLAB/Simulink environment an experimental study of the two types of modules was conducted. The results obtained after the simulations and experiments were compared. Analysis of the results for the two module technologies s...

Chilo zacconius is one of the main rice stem borers in Burkina Faso. A study was conducted on its biology under controlled conditions of 25.46 ±1 °C temperature, 75.94 ±4% relative humidity, and a 12-hour photoperiod. To do this, immature populations of the insect were sampled in rice fields at Bama, western Burkina Faso for mass rearing of the insect pest in the lab. Tavakilian food substrate was used to feed C. zacconius larvae till chrysalid stage, while adults were fed with sugar water. Results showed that the insect had an average life cycle of 65.57±3.12 days, with egg incubation averaging 5.44±0.14 days. The larval phase was the longest one in the insect’s cycle, with an average duration of 48.71±2.46 days, and comprised 7 larval instars. The average lifespan of pupae was 8.1±0.33 days. Average fecundity ranged from 80 to 309 eggs. The average fertility of the insect was 34±6...

Background Vector control strategies have predominantly relied on the use of synthetic chemicals, leading to the widespread of resistance among malaria vector populations. This growing resistance has prompted increased interest in alternative control methods, particularly those based on plant-derived essential oils (EOs). The present study investigates the insecticidal efficacy of five essential oils against field populations of Anopheles gambiae sensu lato from Burkina Faso. The objective was also to assess the current distribution and frequency of resistance-conferring mutations within these mosquito populations. Methods Essential oils were extracted from Cymbopogon citratus, Cymbopogon nardus, Eucalyptus camaldulensis, Lippia multiflora, and Ocimum americanum plants by hydrodistillation, and their chemical composition was analyzed by gas chromatography coupled with mass spectro...

Background Aedes aegypti, the primary vector of Dengue fever in Burkina Faso, breeds in a variety of domestic and peri-domestic water holding containers. The influence of these water containers on the mosquitoes’ ability to survive exposure to chemical insecticides remains unclear. This study investigated the insecticide susceptibility profile of Aedes aegypti in relation to larval habitat types in three districts of Ouagadougou. Methods Adult females reared from larvae collected in “domestic containers” and “car tires” were exposed separately to papers impregnated with deltamethrin, pirimiphos-methyl, and bendiocarb to determine their susceptibility profiles. A subsample of mosquitoes per locality and container type was screened for the F1534C, V1016I and V410L kdr mutations involved in pyrethroid resistance. Results Mosquito population from the three localities showed high resistan...

Cet article explore la relation entre les dépenses d'investissements publics dans le secteur sportif et la croissance économique au Burkina Faso. À l'aide du modèle autorégressif à retards échelonnés (ARDL), l'étude analyse les effets à court et à long terme de ces investissements. Les résultats principaux révèlent une corrélation positive entre le produit intérieur brut (PIB) par habitant et les dépenses d'investissement sportif. La relation suit une dynamique non linéaire, suggérant l'existence d'un seuil minimal d'investissement nécessaire pour déclencher un impact significatif sur la croissance économique. Sur la base de ces conclusions, il est recommandé que l'État burkinabè alloue un budget conséquent à la construction d'infrastructures sportives de qualité, tout en promouvant leur utilisation. De plus, la mise en place d'un mécanisme de gestion efficace des resso...

La stabilité et la légitimité de l’exercice du régime démocratique se fondent sur une large participation de toutes les parties prenantes ou composantes de la société à savoir : les populations à la base, la presses, les religieux, la société civiles etc. En fait, pour que la démocratie conserve sa capacité d'autodéfense, il faut que la majorité des citoyens souhaite vivre sous un tel régime, respecte les règles démocratiques et ait confiance en ses institutions et ses responsables. Tout cela parce que la modernité a des effets très profondes sur les institutions et la vie sociale quotidienne. Par exemple, un de ces effets parmi tant d’autres, est l’élévation du niveau de compétences des citoyens ordinaires dans les sociétés contemporaines, leur aptitude à remettre en cause les formes traditionnelles d’expertise et à produire eux-mêmes des connaissances originales et utiles à l’action...

Abstract BACKGROUND: Health literacy refers to the ability of individuals to obtain, understand, and use health information. The objective of our study was to assess the literacy level of students at Joseph KI-ZERBO University in 2024. METHODS AND MATERIAL: It was a cross-sectional study with analytical purpose carried out from January 15 to June 15, 2024, among students of the University Joseph KI-ZERBO (Ouagadougou) in 2024. A stratified two-stage sampling was carried out, proportionally distributing the participants according to the number of each UFR/Institute, which served as main strata. The sample was determined according to their relative weight in the total population. Cluster analysis was performed using a hierarchical classification to assess student health literacy. RESULTS: The study population consisted of 53.76% men, mostly aged 21 to 25 (60.09%), and single (...
