Ambient PM2. 5 Air Pollution in Ouagadougou, Burkina Faso: Exposure, Attributable Health Burden, and Economic Cost
Mohamed Beidari, Michelline Marie Regina Kansole, Benjamin Bazie
Ambient fine particulate matter (PM2.5) is among the leading environmental causes of premature death, and the highest population-weighted exposures now sit in rapidly urbanizing cities of sub-Saharan Africa. Ouagadougou combines heavy two-wheeler traffic, household biomass use, unpaved road dust, and recurrent Harmattan dust, yet the resulting(...)

Optimisation of Water Consumption in Textile Dyeing Processes in a Sahelian Context: Industrial Audit, Scenario Analysis and Techno-Economic Assessment
Mohamed Beidari, Benjamin Bazie, Michelline Marie Regina Kansole
Water scarcity is one of the most serious constraints on industrial development in the Sahel. Textile dyeing is among the largest industrial users of water, yet in low-income West African countries its water management is poorly documented and rarely optimised. This study reports an industrial audit of water use in a representative Burkinabe t(...)

Optimization of a Building's Indoor Temperature and Sensitive Air-Conditioning Loads Using the BLT-Parpaing Hollow Double Wall
Daouda Sawadogo, Benjamin Kiema, Ousmane Coulibaly
In hot, dry tropical climates (sahelian), such as Ouagadougou (Burkina Faso), high demand for air conditioning in buildings poses a major energy challenge. This study aims to optimize the indoor temperature and sensible air conditioning loads of a typical three-bedroom F3 building with cavity walls, using a double-wall system combining lightwe(...)

Evaluation of the Performance of a Composite Material Made From Lateritic Soil, Crushed Granite, and Cement for Use as the Base Layer of Road Pavement
Etienne Malbila, Lorell Bationo, Adélaïde Lareba Ouedraogo, Hamma Fabien Yonli, Sié Kam, Dieudonné Joseph Bathiébo
The base layer is important for the road pavement structural performance. This study aims to monitor the performance of various local composite materials as road construction materials. To do this, an experimental study treated the improvement of geotechnical properties of a lateritic gravel, initially nonadopted as a base layer, by using thre(...)

Experimental study on the use of crushed granite sand for lithostabilization of lateritic soils in road construction
Yasmine Binta Traoré, Possibo Elise LOMPO, Nafissatou Savadogo, Hamma Fabien Yonli
The use of local materials in road infrastructure provides a sustainable alternative to the high costs of conventional construction materials. However, certain lateritic gravels exhibit insufficient geotechnical properties for direct use in pavement layers. This study evaluated the potential improvement in the physical and mechanical propertie(...)

Valorization of Local Resources for Sealing of Mining Facilities: Characterization of A Geosynthetic Clay Liner Using Clay and Kenaf Fibers from Burkina Faso
Médaninpo Fidèle Yonli, Hamma Fabien Yonli, Gounwendmanaghré Hubert Zongo, Dieudonné Tankoano, Emmanuel Nikièma, David Yemboini Kader Toguyeni
Since the early 2000s, Burkina Faso has experienced significant growth in the mining industry, generating large quantities of waste that require strict management in dedicated facilities. To limit pollutant migration in these mining sites, imported manufactured materials such as Geosynthetic Clay Liners (GCLs) and geomembranes are commonly use(...)

ESTIMATION DES TASSEMENTS DIFFÉRENTIELS DES SOLS DE FONDATION DE BÂTIMENT : CONTRIBUTION DES SONDAGES DE RÉSISTIVITÉ ÉLECTRIQUE
Hamma Fabien Yonli, Gilbert MANO, Mahamadou Koïta, Aristide COMPAORE
To estimate differential settlements of building foundation soils, the site on which the structure is based must be geotechnically surveyed in order to determine the deformation parameters and the thickness of the compressible soil layers in various places. This involves conducting destructive surveys. In this study, the use of geophysical met(...)

Slope Stability Analysis: Case of the West Wall of the EMZ Pit at the Essakane Gold Mine in Burkina Faso (West Africa)
Hamma Fabien Yonli, Michée Banyua Lompo, Nicolas Kagambega, Pierre Sawadogo
Knowledge of the state of stability of mining pits is both a basic condition, an essential axis and a safety benchmark for mining operations. This stability is largely based on the knowledge of the rock mass sheltering the mining works and this requires a perfect characterization of all of its structural formations through mapping (manual or d(...)
