La fiche pédagogique des enseignants d’allemand du Burkina Faso : rôle et utilité pour l’enseignant et pour l’inspecteur
Somdé Camille RAMDE
Parti du constat qu’au Burkina Faso, il n’y a qu’en allemand que l’inspecteur exige de recevoir la fiche de préparation de l’enseignant, et que de plus en plus de voix s’élèvent contre cette pratique, nous avons voulu réfléchir sur la question en nous basant sur les aspects didactiques. Du point de vu des attributions, les enseignants ont le d(...)

Morphological characteristics of Bombax costatum as indicators of the species ethnotypes in Burkina Faso
Wendegoudi Astrid Koala, Blandine Marie Ivette Nacoulma, Larba Hubert Balima, Anne Mette Lykke
Agroforestry species are often exploited by local people based on their morphological characteristics. Knowledge of morphological characteristics and local preferences is useful for species selection and domestication. This study aims to assess the morphological diversity of Bombax
costatum in two climatic zones in Burkina Faso. Semi-structur(...)

Climate–land-use interactions and canopy cover shape soil organic carbon dynamics in African agroforestry landscapes
Gannouka Nadjire, James Nana Ofori, Alimata Arzouma Bandaogo, Eunice Okyere‐Agyapong, Larba Hubert Balima, Amanuel Woldeselassie Gebremichael, Reginald Tang Guuroh, Loyapin Bondé, Oumarou Ouédraogo, Issaka Joseph Boussim, Anja Linstädter
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(...)

Modeling and Experimental Analysis of a Dual-collector Indirect Solar Dryer for Intermittent and Continuous Drying of Bioproducts
Emmanuel Sidwaya Sawadogo, Salmwendé Eloi Tiendrebeogo, Guy Christian Tubreoumya, André Luc Batiana, Zoungrana Windnigda, Téré Dabilgou, Jacques Nébié, Oumar Bailou, Alfa Oumar Dissa, Antoine Béré
This study presents the development and experimental validation of a coupled heat and mass transfer model for a dual-collector indirect solar dryer based on the energy balance of a representative section of the system. The governing equations describe the simultaneous evolution of collector temperature, drying air temperature and product moist(...)

Fruit Productivity of “African locust bean” along a climatic gradient in Burkina Faso
Ezechias Sowionfu SOME, Larba Hubert BALIMA, AdjimaTHIOMBIANO
Parkia biglobosa (Jacq.) R. Br. ex G. Don is highly valued species in many domains as food. However, the overexploitation of its fruits is one of the main causes of the species' vulnerability. Accurate assessment of annual fruit production could contribute in better conservation of the species. This study aims to assess fruit productivity of P(...)

Influences of Intermittent Drying on Local Fruits: The Case of Mangoes, Bananas, Potatoes, and Sweet Potatoes
Emmanuel Sidwaya Sawadogo, Salmwendé Eloi Tiendrebeogo, Guy Christian Tubreoumya, Zoungrana Windnigda, André Luc Batiana, Desiré Zerbo
In the context of promoting local agricultural products in the face of significant post-harvest losses in West Africa, optimizing drying methods is a key challenge. This research explores the impact of various intermittent drying regimes applied to four fresh products, namely mangoes (Mangifera indica), bananas (Musa sapientum), potatoes (Sola(...)

Theoretical and Experimental Study of The Performance of The Flat-Plate Thermosiphon Collector of A Solar Water Heater Using Locally Available Materials
André Luc Batiana, Salmwendé Eloi Tiendrebeogo, Emmanuel Sidwaya Sawadogo, Guy Christian Tubreoumya, Desiré Zerbo, Alfa Oumar Dissa
Our work focuses on a numerical and experimental study of a flat plate solar collector designed and tested at the Ecole Normale Supérieure (ENS) in Burkina Faso at the Ouagadougou annex site. This device converts solar radiation into thermal energy. It was designed using locally available materials by a local designer. The objective of our wor(...)

Experimental study of stratification and the impact of insulation thickness in local solar water heater storage tanks during the rainy season in Burkina Faso
André Luc Batiana, Salmwendé Eloi Tiendrebeogo, Guy Christian Tubreoumya, Emmanuel Sidwaya Sawadogo, Traoré Carmelle Annou Evelyne
Burkina Faso relies mainly on fossil fuels for its energy production; however, given the rapid development of renewable energy technologies in recent years, Burkina Faso has been seeking other inexhaustible and environmentally friendly sources of energy, among which solar energy is considered the most important. Domestic hot water production i(...)

Testing the ecological apparency hypothesis in Sudano‑Sahelian parklands in Burkina Faso
Larba Hubert Balima, Alexis Sompougdou, Benjamin Lankoandé, Zomizi Frank Calixte Coulibaly, Philippe Bayen, Jules Bayala
Agroforestry, by integrating trees and shrubs into agricultural systems, serves as an effective nature-based solution for strengthening climate
resilience and food security. While its adoption has received increasing research attention in West Africa, the relationships between plants’ apparency and local importance remain poorly understood. T(...)

Theoretical Optimization of Performance Indicators for the Flat-plate Solar Collector of a Thermosiphon Solar Water Heater
André Luc Batiana, Salmwendé Eloi Tiendrebeogo, Guy Christian Tubreoumya, Emmanuel Sidwaya Sawadogo, Bagré Sara
Solar energy is currently one of the most promising sources for meeting global energy needs. Hot water production using solar water heaters represents one of the most promising applications of solar energy for countries like Burkina Faso. However, the efficiency of solar system performance indicators remains a challenge, especially during peri(...)

Biotic and abiotic drivers of biomass carbon storage in periurban forests in Burkina Faso
Larba Hubert Balima, Moussa Ganamé, Philippe Bayen, Henry Kiemtoré, Lassané Nakoulma, Mohamed Cissé, Issouf Zerbo, Adjima Thiombiano
Urban and peri-urban forests are vital nature-based climate solutions in urban centers undergoing
rapid urbanization and rising temperatures. While their ecological role in carbon sequestration is
documented in West Africa, how environmental factors affect aboveground carbon (AGC) storage in
peri-urban forests remains poorly understood. Thi(...)

La supervision pédagogique des élèves professeurs: analyse du comportementdes encadreurs pédagogiques
Innocents OUEDRAOGO, Walièma Eric SOME, Adama KABRE
Depuis 2020, l’État burkinabè a fait de la formation professionnelle l’unique voie d’entrée dans l’enseignent public. La formation des futurs enseignants est assurée par l’École Normale Supérieure (ENS) en deux phases : une phase théorique d’une année à trois ans selon le profil d’entrée et une phase pratique d’une année scolaire qui met l’app(...)

ANALYSE DES PRATIQUES ENSEIGNANTES DANS L’ORGANISATION DES ACTIVITÉS COMMUNICATIVES AU COURS D’ANGLAIS DANS LES LYCÉES SCIENTIFIQUES AU BURKINA FASO
SORÉ Wendinmi Abdoul Fataf, BATIONO Jean-Claude
Plusieurs résultats de recherches révèlent que l’organisation des activités communicatives au cours d’anglais au Burkina Faso, constitue un véritable défi pour les enseignants à cause du problème des effectifs pléthoriques d’apprenants. Les lycées scientifiques créés dans le cadre du PNDES 2016-2020 semblent constituer une exception. La présen(...)
