Higher diversity, denser stands and greater biomass in peri-urban forests than in adjacent agroforestry systems in Western Burkina Faso: implications for urban sustainability
Balima Larba Hubert, Zerbo Issouf, Bayen Philippe, Kiemtoré Henri, Ganamé Moussa, Cissé Mohamed & Thiombiano Adjima
Urban and peri-urban forests greatly contribute to the well-being of urban dwellers in West Africa. However, increasing urban densification and spatial expansion negatively affect the functioning of urban ecosystems. Therefore, highlighting the negative impacts of land use change on the ecological attributes of urban landscapes is fundamental(...)

Search for Qualified Soil for the Production of Low-Energy Biobased Composite Materials
SANDWIDI Sayouba , HARO Kayaba , DABILGOU Téré , Sinon Souleymane , SANOGO Oumar , KOULIDIATI Jean, & BERE Antoine
The development of earth-based bio-sourced materials requires a thorough analysis of the study soil. For the present study, we took five (05) soil samples from a tunnel-digged quarry in the layer between 0.5 m and 5 m : white clay (MSB-BL), red clay (MSB-RG), weak clay or sandy clay (MSB-FB), strong clay (MSB-FR) and mixture (MSB-ME). To verif(...)

THOMAS SANKARA DANS LES PAYS GERMANOPHONES :LA PRATIQUE DU CONTRE-DISCOURS COMME DEMARCHE POLITIQUE
YAMEOGO, Mohamed
La réception de Thomas Sankara dans les pays germanophones témoigne de ce qu’il n’est plus l’héritage
de son seul pays, le Burkina Faso. Sa vie et l’impact de son oeuvre politique sous la révolution d’août
1983 interrogent et suscitent à la fois de l’admiration. En quatre années de gestion du pouvoir, il a su
trouver la formule pour tracer(...)

MECANISMES D'INTEGRATION DES EMPRUNTS NOMINAUX DU KUSAAL
BAMBARA Houssouyam Appoline, KOHOUN Lamoussahan dite Sara
Notre communication porte sur les mécanismes d’intégration des emprunts nominaux du kusaal. Langue de type gur, elle est l’une des langues minoritaires parlée au sud-est du Burkina Faso, plus précisément à Zoaaga et à Youga. Le lexique d’une langue est un ensemble en constantes mutations. Son enrichissement passe, non seulement par la créatio(...)
