Indigenous African soil enrichment as a climate-smart sustainable agriculture alternative

This report by Frontiers in Ecology and the Environment describes a current indigenous soil management system in West Africa, in which targeted waste deposition transforms highly weathered, nutrient- and carbon-poor tropical soils into enduringly fertile, carbon-rich black soils, hereafter “African Dark Earths” (AfDE). AfDE provide a model for improving the fertility of highly degraded soils in an environmentally and socially appropriate way, in resource-poor and food-insecure regions of the world. The method is also “climate-smart”, as these soils sequester carbon and enhance the climate-change mitigation potential of carbon-poor tropical soils. »

Status of the world’s soil resources report

This report is a reference document on the status of global soil resources that provides regional assessments of soil change. The report states that soils are rapidly deteriorating due to soil erosion, nutrient depletion, loss of organic carbon, soil sealing and other threats. The report notes how there is a general consensus on soil-related strategies that can, on the one hand, increase the supply of food, while on the other, minimize harmful environmental impacts. »
