Summary
This multidisciplinary systematic review evaluates soil carbon sequestration as a greenhouse gas removal technology for agricultural systems, identifying five categories of implementable practices: productivity optimisation, reduced soil disturbance, minimised carbon removal, external carbon addition, and enhanced in-system carbon inputs. The authors synthesise biophysical, economic and social evidence to characterise implementation barriers, incentives and externalities at farm level, providing a framework to bridge the gap between global sequestration potential assessments and practical policy operationalisation.
UK applicability
The review's focus on farm-level implementation, UK-affiliated authorship (including researchers from Scottish Agricultural College and UK universities), and discussion of temperate cropping and grassland systems suggests direct relevance to UK agricultural policy and practice. The framework offers guidance for UK policymakers and land managers navigating the practical deployment of SCS measures compatible with food security objectives.
Key measures
Soil carbon sequestration potential; farm-level uptake compatibility; economic barriers and incentives; social and environmental externalities; technical quantification capacity
Outcomes reported
The study identifies specific soil carbon sequestration (SCS) practices with potential for positive farm-level impact and global uptake, categorised across five intervention types. It provides a multidisciplinary assessment of economic, non-cost barriers and incentives for land manager implementation, and evaluates potential externalised impacts of these measures.
