Summary
This review by Rattan Lal, a leading authority on soil carbon and land management, examines the critical linkages between soil organic matter and global food security. Published in Renewable Agriculture and Food Systems, the paper likely synthesises evidence on how SOM depletion undermines soil fertility, water retention, and crop productivity, and presents agronomic and policy options to restore SOM. Lal's work in this area consistently argues that improving SOM globally could simultaneously address food insecurity, land degradation, and climate mitigation.
UK applicability
Whilst the paper is global in scope, the findings are broadly applicable to UK arable and mixed farming systems, where SOM depletion in intensively managed soils is a recognised challenge; UK policy frameworks such as the Sustainable Farming Incentive explicitly incentivise SOM improvement, making this research contextually relevant.
Key measures
Soil organic carbon (SOC) stocks (Mg C/ha); crop yield responses to SOM levels; food security indices; SOM restoration rates under management interventions
Outcomes reported
The paper likely examines the relationship between soil organic matter (SOM) levels and agricultural productivity, food supply resilience, and soil health indicators. It probably reports on how SOM degradation threatens food production capacity and outlines management strategies to restore and maintain SOM stocks.
