Valaire Séraphin Ouehoudja Yaro, Loyapin Bondé , Pawend‑taoré Christian Bougma, Issoufou Sedgo, Reginald Tang Guuroh, Amanuel Woldeselassie Gebremichael, Tiga Neya, Anja Linstädter, Oumarou Ouédraogo
Greenhouse gas (GHG) emissions from prescribed fires are poorly investigated, resulting in a high uncertainty in GHG budgets. Using, a carbon mass balance approach and experimental prescribed fires in 80 plots, this study assessed carbon emissions and established emission factors (EFs) for carbon dioxides (CO2), carbon monoxide (CO), and meth(...)

Exploring the Added Value of Sub-Daily Bias Correction of High-Resolution Gridded Rainfall Datasets for Rainfall Erosivity Estimation
Roland Yonaba, Lawani Adjadi Mounirou, Amadou Keïta, Tazen Fowé, Cheick Oumar Zouré, Axel Belemtougri, Moussa Bruno Kafando, Mahamadou Koïta, Harouna Karambiri and Hamma Yacouba
This study evaluates the impact of sub-daily bias correction of gridded rainfall products (RPs) on the estimation rainfall erosivity in Burkina Faso (West African Sahel). Selected RPs, offering half-hourly to hourly rainfall, are assessed against 10 synoptic stations over the period 2001–2020 to appraise their accuracy. The optimal product (th(...)

Granulometry Assessment of Lom Pangar Dam Sediments (East-Cameroon)
Rodrigue Fotie Lele1,2*, Mihaela Amalia Diminescu3, Issoufou Ouedraogo1,4, Annette Madelene Dăncila3, Souleymane Pelede1, Alphonse Emadak5, Martin Lompo1
The Lom Pangar dam, the largest reservoir in Cameroon with a storage capacity of 6 km3 and a 30 MW hydropower plant, primarily regulates the hydrologic regime of the Sanaga River to maintain hydropower efficiency during dry seasons and enhance downstream hydropower plant performance. Understanding and managing sediments are crucial for the sus(...)

Dynamique d'occupation et d'utilisation des terres dans la Forêt Classée de Tiogo au Burkina Faso : caractérisation, moteurs et impacts sur la diversité et le stock de carbone ligneux
KONATE I., ILBOUDO D., DAYAMBA S.D. ., TRAORÉ S., SAWADOGO L., HIEN, M.
L’état de dégradation des forêts est une préoccupation mondiale particulièrement pour l’Afrique. De ce fait, plusieurs forêts classées sont de plus en plus menacées d’extinction dont les causes sont anthropiques et climatiques. L’étude a évalué la dynamique du couvert végétal et ses implications sur le stock de carbone aérien et la diversité l(...)

Review on parameters influencing the efficiency of the dual-medium thermocline storage system
Bowendkuni Armand Korsaga, Jacques Nébié, Boubou Bagréa, Abdoulaye Kaboréa,Iliyassé Konkoboa, Tere Dabilgoua, Bernard Nanaa, Tizane Daho and Antoine Béré
Thermal storage systems are needed to overcome solar intermittency and make this energy source more flexible and competitive for concentrated solar power plants. Single-tank sensible heat storage using both fluids and materials is a promising option for reducing storage costs and promoting the development of concentrated solar power. This work(...)

Hooded Vultures Necrosyrtes monachus are still declining in West Africa: a nearly 50-year assessment study (1969–2019)
Clément Daboné, Idrissa Ouédraogo, Adama Ouéda, Lindy J Thompson & Peter DM Weesie
Large-scale declines in vulture populations have been recorded in West Africa. One concern is that the current trend in Hooded Vulture Necrosyrtes monachus populations in West Africa is poorly known. To help fill this knowledge gap, we conducted nationwide road counts in Burkina Faso, Mali and Niger, using (where possible) the same routes and(...)

Unravelling the Impacts of Climate Variability on Surface Runoff in the Mouhoun River Catchment (West Africa)
Cheick Oumar Zouré, Arsène Kiema, Roland Yonaba and Bernard Minoungou
This study assesses the impacts of climate variability on surface runoff generation in the Mouhoun River Catchment (MRC) in Burkina Faso, in the West African Sahel. The study uses a combination of observed and reanalysis data over the period 1983–2018 to develop a SWAT model (KGE = 0.77/0.89 in calibration/validation) further used to reconstit(...)

Citizens and urban greening: Do Bobo Dioulasso dwellers participate in greenhouse gas mitigation through urban forestry and greening?
Harouna Derra, Traoré, Sidnoma Abdoul Aziz, & Kaboré Gouwidida Elice
Urban trees and forests play a vital role in maintaining the balance of urban ecosystems and mitigating global warming. However, due to the lack of data and information on the potential of urban forests, their importance remains largely unknown. This study aims to describe citizens' perceptions of trees and assess the forest community's densit(...)

Experimental Study of a Diesel Engine Incorporating a "KALAMA" Screw and Operating on Vegetable Oils
Gounkaou Yomi Woro, , Diané Ali , Koala Lucmane , Daho Tizane , Sanogo Oumar , Béré Antoine
The vegetable oil is an alternative fuel that complements or substitutes for fossil fuels. However, its use in diesel engines gives rise to a number of difficulties, especially at low engine power levels. To resolve these problems, improving the thermal conditions in the engine's combustion chamber is one of the solutions being considered. Thi(...)

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(...)

Ethnobotany and conservation of the species Celtis toka (Forssk.) Hepper & J.R.I. wood: A way forward for sustainable use in Burkina Faso
Dabré Zaïnabou, Zerbo Issouf, Nacoulma Blandine Marie Ivette, Soro Dodiomon, Thiombiano Adjima
Celtis toka (C. toka), a critically endangered mystical plant, is a highly valued and overharvested multiuse tree species by local population in Burkina Faso. The ethnobotany of C. toka can lead to its sustainable use, therefore it is a great challenge because little information is available on this aspect concerning the species in Burkina Fas(...)

Air pollution is one of the major global threats to human health. In Burkina
Faso, more than 80% of the population uses solid fuels as the main source of
cooking energy. This paper reports a comparative study on the exposure of
household to the carbon monoxide (CO) and particulate matter (PM2.5) emitted by improved cookstoves (ICS) or tradi(...)
