Decisions on the possible types of practices and investments can be informed using evidence of potential benefits. Using farm household data together wit...
Controlled grazing management is considered as an effective strategy to enhance soil carbon sequestration, but empirical evidences are scarce. Particularly, the role of livestock exclusion related to soil carbon sequestration is not well understood in arid and semiarid savannas of Africa. We inve...
An enormous effort is underway in Ethiopia to address soil erosion and restore overall land productivity. Modelling and participatory approaches can be used to delineate erosion hotspots, plan site- and context-specific interventions and assess their impacts. In this study, we employed a modellin...
Speargrassseverely constraints crop production in the sub-humid lowlands of West Africa. Researchers have identified and demonstrated effectivemanagement techniques but the adoption rate among farmers is still low. Data were collected from 41 communities in Cross River, Kogi and BenueStates in Ni...
Historical and recent aerial photograph and satellite images were analysed to study the change of land use/land cover and soil degradation in different agroecological zones of Nigeria and Benin. The sites were characterized by an expansion of farmland at the expense of forest and shrub, fallow an...
