“…Extensive research has been conducted into the broader frameworks of integrated soil fertility management [130][131][132][133][134][135][136][137], conservation agriculture [138][139][140][141][142][143], erosion control [144][145][146][147][148], and improved grazing management [149][150][151]. There is also a wealth of information on the benefits of specific practices such as short legume rotations (improved fallows) [152][153][154][155][156][157][158], agroforestry systems [159][160][161][162][163][164][165], and no-till systems [166][167][168][169][170].…”

Abstract:The primary cause of soil degradation in sub-Saharan Africa (SSA) is expansion and intensification of agriculture in efforts to feed its growing population. Effective solutions will support resilient systems, and must cut across agricultural, environmental, and socioeconomic objectives. While many studies compare and contrast the effects of different management practices on soil properties, soil degradation can only be evaluated within a specific temporal and spatial context using multiple indicators. The extent and rate of soil degradation in SSA is still under debate as there are no reliable data, just gross estimates. Nevertheless, certain soils are losing their ability to provide food and essential ecosystem services, and we know that soil fertility depletion is the primary cause. We synthesize data from studies that examined degradation in SSA at broad spatial and temporal scales and quantified multiple soil degradation indicators, and we found clear indications of degradation across multiple indicators. However, different indicators have different trajectories-pH and cation exchange capacity tend to decline linearly, and soil organic carbon and yields non-linearly. Future research should focus on how soil degradation in SSA leads to changes in ecosystem services, and how to manage these soils now and in the future. OPEN ACCESS

“…There are many examples of this kind of research, including land management and innovation in Honduras (Sherwood and Larrea 2001), colonists' perception of fertility in Brazil (Muchagata and Brown 2000) and integrated soil fertility management in an African context (Defoer 2002). Another example is CIFOR's (International Center for Forestry Research) project on Adaptive Collaborative Management (ACM) using participatory learning and action research in forest management (http://www.cifor.cgiar.org/acm/projects/).…”

The article explores the action research process throughout a land management research project, with the ambition to reflect upon action research as a working approach. It is shown how this process is experienced from a researcher's point of view and it critically analyses its methodology and process, outcome and the role of the action researcher.The learning environment known to farmers and framed by local institutions and practical experimentation, embedded in the local worldview, constituted a necessary starting point for achieving motivation and practical outcomes. Tight feedback loops between practice and reflection enabled joint learning and innovation and rapid implementation of measures suggested by the farmers. The approach could be particularly useful for local NGOs and local universities.

“…Farmers' understanding of yield variability could be incorporated from the start of the experiments, thus allowing faster progress in the design of successful alternatives. Similarly to PLAR (Defoer, 2002), our approach can be scaled-out to facilitate learning by farmers, extension workers and researchers.…”

“…Secondly, strong farmers' participation in the design process may enhance the relevance of the innovations to specific farmer contexts. While participatory research emphasises the generation of qualitative insights (Dorward et al, 2003;Van Asten et al, 2009), Participatory Learning and Action Research (PLAR) was proposed to combine qualitative and quantitative insights (Defoer, 2002). In PLAR, qualitative participatory research provides information that strengthens quantitative assessments, e.g.…”
