This report evaluates the economic benefits and carbon sequestration potential of Sustainable Land Management (SLM) practices, specifically Conservation Agriculture and Integrated Soil Fertility Management, for smallholder farmers in Siaya County, Western Kenya, where subsistence agriculture faces significant soil degradation.

This research paper evaluates the performance of Tier 1 (T1) and Tier 2 (T2) IPCC carbon accounting methods for estimating soil organic carbon (SOC) stocks and flows in the Argentinean Pampa Region from 1900 to 2006, finding that the T2 method, developed using the RothC model, provides more realistic regional inventories than the T1 method.

This research paper by the Stockholm Environment Institute examines the potential and barriers for land-based mitigation technologies and practices (LMTs) in China. It finds that while forestry has been the primary focus for carbon sequestration, other sectors like agriculture, grasslands, and wetlands remain underexploited. The report highlights a lack of standardized methodologies and a fragmented policy landscape, suggesting that these must be addressed to meet China's 2060 net-zero goal.

A study of a temperate deciduous oak forest in south east England analyzed the components of soil CO2 efflux (Rs), finding that autotrophic respiration (Ra)—comprising root (Rr) and mycorrhizal hyphae (Rm) respiration—contributes 56% of the total flux, with Rm acting as a carbon "overflow tap" linked to gross primary productivity (GPP).

The authors introduce MILLENNIA, a peat age-cohort model designed to address shortcomings in global soil models regarding the representation of long-term soil organic carbon (SOC) accumulation and dynamic hydrological processes, specifically water table depth (WTD). The model's predictions for SOC accumulation and peat ages were validated against observations from a UK peatland site.
