Summary
This multi-author review evaluates the 4p1000 initiative—a proposal to increase global soil organic carbon by 0.4% annually as a climate mitigation strategy. The authors assess both the technical potential and practical constraints of soil carbon sequestration across diverse agroecological contexts, examining how realistic and scalable such an approach might be for sustainable development. The paper appears to identify significant opportunities alongside notable limitations in translating the initiative into field-level practice.
UK applicability
The findings are relevant to UK agricultural policy and carbon sequestration targets, particularly regarding temperate soil management and the feasibility of soil carbon credits. However, the global scope may require contextualisation for UK-specific soil types, climate and regulatory frameworks.
Key measures
Soil organic carbon stocks; sequestration rates; implementation barriers; policy and technical feasibility across farming systems
Outcomes reported
The paper examines the opportunities, limitations and challenges for implementing soil organic carbon sequestration as a sustainable development strategy under the 4p1000 initiative framework. It assesses the feasibility and constraints of increasing soil carbon across diverse agricultural and land-use systems globally.
