    This chapter is a case study that tests hypotheses in order to determine if political factors can reduce violence in cases of climate-change-induced or -aggravated agro-pastoral conflicts over natural resources. Three West African countries were selected because of their common socio-economic and environmental characteristics and because they host comparable farmer–herder conflicts: Burkina Faso, Côte d’Ivoire and Ghana. The level of farmer–herder conflicts is estimated to have risen between 1960 and 2000 in the three countries.

    Land degradation and desertification are among the biggest environmental challenges of our time. In the last 40 years, we lost nearly a third of the world’s arable farmland due to erosion, just as the number of people to be fed from it almost doubled. That’s why the UN General Assembly declared 2015 as the International Year of Soils. And the good news is that this new report shows that while Africa remains the most severely a«ected region, the benefit of taking action across the continent outweighs the cost of implementing it: not just by a little, but by a factor of seven.

    Despite the many advantages of sustainable intensification (SI), the level of adoption of SI practices in African smallholding farms is still very low, posing the need for adequate methods for monitoring farm sustainability. Macronutrient flows and balance in agricultural systems are important for assessing the system sustainability as they indicate what supply risks an agricultural system runs, how resilient the system is to these risks, and what environmental impacts arise from the use of that essential resource.

    Modelling socio-ecological systems, in which social and ecological systems interact each other and co-evolve, are useful for supporting decisions in managing landscape ecosystems. Inter-linking socially interactive decision-making to relevant ecological processes faces a great challenge due to at least two reasons: (1) the inherent mismatches in the spatial and temporal scales the considered processes operate, (2) differences in relevant methods for modelling the processes and (3) different data availabilities for the processes.

    In the West African drylands, SOC sequestration is seen as one of the prominent strategies to both enhance the resilience of agro-ecosystems and mitigate global greenhouse effects. However, there is a dearth of baseline data that impede the design of site-appropriate recommended management practices (RMPs) to improve and sustain SOC accrual. In this study, the Land Degradation Surveillance Framework (LDSF), a nested hierarchical sampling design was used to assess SOC and its spatial variability across the semi-arid zones of Ghana (Lambussie), Burkina Faso (Bondigui) and Mali (Finkolo).

    West African savannas are experiencing rapid land cover change that threatens biodiversity and affects ecosystem productivity through the loss of habitat and biomass, and carbon emissions into the atmosphere exacerbating climate change effects. Therefore, reducing carbon emissions from deforestation and forest degradation in these areas is critical in the efforts to combat climate change. For such restorative actions to be successful, they must be grounded on a clear knowledge of the extent to which climate change affects carbon storage in soil and biomass according to different land uses.
