Summary
This 2016 Scientific American article by Reganold and Glover addresses soil degradation as a critical constraint to agricultural productivity and food security in Africa, and reviews evidence-based soil management practices—likely including conservation agriculture, agroforestry, and organic inputs—that can restore soil function and support smallholder livelihoods. The authors appear to argue that soil health improvement is both technically feasible and economically viable, positioning regenerative approaches as a pathway to sustainable intensification in sub-Saharan African contexts.
UK applicability
Whilst UK soils face different climatic and management pressures than African soils, the underlying principles of soil organic matter building, reduced tillage, and integrated nutrient management are relevant to UK farming systems. However, the specific technical recommendations and economic analyses are likely tailored to tropical and subtropical conditions with different soil types and socioeconomic constraints.
Key measures
Soil health indicators (fertility, organic matter, microbial activity, water retention); crop productivity; farm income; adoption rates of soil management practices
Outcomes reported
The paper likely examines soil degradation challenges across African farming systems and evaluates evidence-based soil management approaches to restore fertility and productivity. As suggested by the title, it may assess the feasibility and impacts of soil remediation strategies suited to African agroecological contexts.
