    Abstract Farmers managing agroecological systems across sub-humid West Africa face a variety of challenges in meeting their needs. In the face of adverse conditions, farmers have successfully managed agroforestry parklands to create an ecological equilibrium. However, climate change presents a challenging and new disturbance to farmer livelihood strategies. Using a qualitative approach and a rural livelihood framework, we analyzed and assessed farmer livelihood strategies, attitudes, and responses to climate change. Results showed that farmers are constantly changing management strategies through flexible and adaptable decision-making to mitigate negative disturbances, but climate change as a primary driver to change cannot be distinguished from other normal challenges that farmers face inter- and intra-annually. Through the accumulation of knowledge and adaptive management, farmers in Kedougou derive a variety of livelihood strategies to reduce risk in the face of uncertainty and variable climatic conditions. Furthermore, farmers used trees on farms to derive a multitude of ecosystem services provided not only provisioning services such as fuel, food, and fiber, but increased biodiversity, nutrient cycling, and climate regulation. Additional research is still needed to understand to what extent the inclusion of trees on farms affect various biophysical properties as well as rationale behind species choice.

  3. Article ; Online: Temporal Climate Variability and Staple Cereals in Southern Burkina Faso

    Abstract Farming activities are the primary source of livelihood for agro-pastoral communities in the Sahel biogeographic zone in Burkina Faso. The climate variability and change have a direct impact on performance, quantity, and quality of staple cereals yields. Understanding how the crops respond to climate variability is crucial for ensuring adequate crops management and food security. Hence, this paper aims at investigating how different staple cereals respond to certain indicators of climate variability at inter-annual and inter-decadal levels in southern Burkina Faso. In our study, we use regression models and scatter plots. The model results show that climate variability has mixed effects on cereal yields. The study demonstrates the interdependencies among district-scale cereal yields in the study area including maize, sorghum, and millet casually associate with the inter-annual variation of selected climate variability indicators. Maize yields, for example, relate strongly to the rainfall amount variation (R2 = 51.8%) showing high moisture dependence during critical growth stages. Conclusions emphasize the adoption of efficient water conservation and utilization platforms, especially those that have evidently increased yields and strengthening of forecasts dissemination and related climate information services.

    Abstract The negative image of the Sahel is a stranglehold on the great potential for development in the region. A more balanced narrative can trigger action for a productive Sahel and can be based on innovative approaches and a conducive policy environment to value natural resources. Despite a rich set of information, the potential of the Sahel is still not flagged with sound knowledge that can be opposed to the conspicuous depressed perception. Positive transformation pathways require many improvements in the governance, finance and equity issues with a particular reference to the youth and women. The Sahel can sustain its sustainable development if transformation occurs in natural resources management. The paper analyses: i) the opportunities related to natural resources; ii) the potential and challenges for deep rapid transformation based on sound resources management practices; iv) areas for job creation and livelihood protection; and v) new models for financing these developments.

    Abstract Partly due to severe lack of instrumental climate data, the drivers of the African climate, their interactions and impacts are poorly understood. The paper demonstrates the prospects and applications of dendroecological and stable isotope techniques, such as to reconstruct climate variability, trends and atmospheric circulation patterns, to fill the knowledge gap in ecosystem productivity and hydrological cycle in different climatic zones of Africa. We summarize the contribution of tree-ring analyses to validation of climate and hydrological models for improved scenarios, and to identify agroforestry species with the ability to acclimate to exacerbated climate conditions. A high number of African tree species shows datable annual tree rings and may reach multi century age. To advance dendrochronology in Africa, collaborative efforts in capacity building of African universities and research organizations are needed.

    Abstract This work presents the modeling and optimization of an indirectly irradiated solar receiver. A numerical model of the cavity-absorber block is put forward with the coupling of the net-radiation method using infinitesimal areas and a CFD code. An iterative method with a relaxation factor made it possible to obtain the temperature distribution and the developed code was implemented in the form of UDF and used as boundary conditions in the CFD model of the absorber to simulate the flow of air and heat transfer. The good ability of the receiver to transfer heat to the fluid is proved with a 92% thermal efficiency obtained. Then the combination of the Kriging surface response method and the MOGA allowed the mathematical optimization of the receiver. The multi-objective optimization made it possible to obtain 3 candidates giving the best combinations of design parameters from the fixed objectives. Three bullet points, highlighting the customization of the procedure. •A practical analysis using the net-radiation method using infinitesimal areas is applied for cavity radiative exchange model.•The code developed for the cavity is implemented in the boundary conditions at the level of the ANSYS Fluent CFD model allowing the simulation of the conjugated transfers within the absorber.•The optimization method proposed is the combination of the Kriging surface response method for quantitative and qualitative analysis of the design parameters and MOGA to obtain different combinations seeking to maximize or to minimize the chosen parameters.
