Water Resources in the Sahel and Adaptation of Agriculture to Climate Change: Burkina Faso
Babacar Lèye, Cheick Oumar Zouré, Roland Yonaba and Harouna KarambiriIn West Africa, a shift in climate conditions since the 1970s is evidenced by a decrease in average annual rainfall and an increase in temperatures between 1931–1960 and 1968–1990. The latter period was followed by a rainfall recovery since the late 1990s in the western Sahel. The prolonged...

Spatial and transient modelling of land use/land cover (LULC) dynamics in a Sahelian landscape under semi-arid climate in northern Burkina Faso
Roland Yonaba, Mahamadou Koïta, Lawani Adjadi Mounirou, Tazen Fowé, Pierre Queloz, Angelbert Chabi Biaou, Dial Niang, Cheick Oumar Zouré, Harouna Karambiri, Hamma Yacouba,Sahelian landscapes have gone through rapid changes over the past decades under high pressure from an ever-growing population, climate hazards and land degradation. Understanding drivers of change and forecasting LULC dynamics in time and space are critical for sustainable land management. This...

Water Dynamics under Drip Irrigation to Proper Manage Water Use in Arid Zone
Ouédraogo, S. , Bawindsom Kébré, M. and Zougmoré, F.The water resources reduction due to climate changes and also population increase, have contributed to increasing the constraint on water disponibility and accessibility. In the agricultural field, we need moderate soil and water resources management. This work aims to simulate water dynamics in...

How Is Forest Landscape Restoration Being Implemented in Burkina Faso? Overview of Ongoing Initiatives
Barbara Vinceti * , Michel Valette , Ali Lardia Bougma and Arturo TurillazziLand degradation affects a significant portion of the Earth’s ice-free land area and several countries have embraced the challenge of restoring large parts of their degraded lands. Success in these efforts depends on various factors, including the amount of resources invested, the technical...

A dynamic land use/land cover input helps in picturing the Sahelian paradox: Assessing variability and attribution of changes in surface runoff in a Sahelian watershed.
Roland Yonaba, Angelbert Chabi Biaou, Mahamadou Koïta, Fowé Tazen, Lawani Adjadi Mounirou, Cheick Oumar Zouré, Pierre Queloz, Harouna Karambiri, Hamma YacoubaIn Sahelian landscapes, land use/land cover (LULC) dynamics and climate variability are already known to affect the water cycle. In its current practice however, hydrological modelling does not account for LULC changes. This issue pertains to rapidly evolving watersheds and might result in...

Multi-scale analysis of runoff from a statistical perspective in a small Sahelian catchment under semiarid climate.
Lawani Adjadi Mounirou, Cheick Oumar Zouré, Roland Yonaba, Jean- Emmanuel Paturel, Gil Mahé, Dial Niang, Hamma Yacouba, Harouna KarambiriIn Sahelian and semi-arid regions, understanding the runoff processes and at different spatial scales is critical to assess sources of variation and further improve distributed modelling. In this study, through a multi-scale analysis, runoff measurements on different soil surface features and at...

Solid Waste Management in Africa: Governance Failure or Development Opportunity?
Linda Godfrey, Mohamed Tawfic Ahmed, Kidane Giday Gebremedhin, Jamidu H.Y. Katima, Suzan Oelofse, Oladele Osibanjo, Ulf Henning Richter, Arsène H. YonliWaste management is a social, economic, and environmental problem facing all African countries. If the 2030 Agenda for sustainable development is to be achieved, sustainable waste management approaches must be an environmental and public health imperative deserving political priority. Current...

Radiation dose assessment of soil from Ijero Ekiti, Nigeria
M. R. Usikalu, P. P. Maleka, N. B. Ndlovu, S. Zongo, J. A. Achuka and T. J. Abodunrin,The activity concentration of 238U, 232Th and 40K in the soils of mining and living areas of Ijero Ekiti were determined using hyper pure germanium gamma ray spectrometer. The mean concentrations of 238U, 232Th and 40K were found to be 128.05 Bqkg−1, 24.8 Bqkg−1 and 455.05 Bqkg−1,...

Enrichment of ferrous iron in the bottom water of Lake Nyos
Minoru Kusakabe, Rosine E. Tiodjio, Bruce Christenson, Kazuto Saiki, Takeshi Ohba, Muga YaguchiCet article s’est penché sur le comportement des métaux ferreux dans les profondeurs du lac Nyos. En effet, le constat de l’enrichissement en Fe2+ de l’eau du fond du lac a été fait après le début du dégazage artificiel. Dans la couche inférieure du lac (205,5-209,5 m), Fe2+ et...

Modelling the water balance on farming practices at plot scale: Case study of Tougou watershed in Northern Burkina Faso.
Cheick Zouré, Pierre Queloz, Mahamadou Koïta, Dial Niang, Tazen Fowé, Roland Yonaba, David Consuegra, Hamma Yacouba, Harouna KarambiriIn the Sahel region, farmers have adopted various farming practices to improve agricultural yields in order to offset an increasingly variable climate regime and the extension of degraded land. This study analyses the functional behaviour of such three selected water-harvesting techniques (stone...

Predicting attenuation of solar radiation (UV-B, UV-A and PAR) in waste stabilization ponds under Sahelian climatic conditions
MAIGA Ynoussa , WETHE Joseph, OUATTARA Aboubakar Sidiki, TRAORE S. AlfredBecause of its importance in pathogen removal and algal productivity in waste stabilization ponds, sunlight penetration was measured in microcosms and in situ under Sahelian climatic conditions. The different wavelengths were detected using a submersible radiometer equipped with three sensors:...
