A Cure for Africa's Soil

Summary

This Scientific American narrative review by soil scientists Reganold and Glover synthesises evidence on soil degradation as a critical barrier to agricultural productivity and food security across sub-Saharan Africa, and examines evidence-based farming interventions—potentially agroecological or conservation agriculture approaches—as pathways to restore soil health and build agricultural resilience. The authors likely integrate findings on how soil restoration supports both crop production and broader development outcomes in African farming systems. As a feature article rather than primary research, the piece functions as a synthesis of existing knowledge for a broad readership, situating soil health within the wider context of African food security challenges.

UK applicability

Whilst the paper focuses on sub-Saharan African soil and farming contexts, which differ substantially from UK temperate and institutional conditions, the underlying soil science principles and some regenerative practices (e.g. reduced tillage, organic matter building) have relevance to UK soil restoration priorities, particularly for improving soil carbon and structure on degraded arable land.

Key measures

As suggested by the title and journal context, likely soil health indicators (organic matter, fertility, structure) and agricultural productivity outcomes in sub-Saharan African contexts, though specific metrics are not detailed in available metadata.

Outcomes reported

The article synthesises evidence on soil degradation as a constraint to agricultural productivity and food security in Africa, and examines farming practices—potentially including agroecological or conservation agriculture approaches—as pathways to soil restoration and agricultural resilience.
