Soil organic carbon sequestration potential of agricultural soils in Europe

CARBOSEQ

Research

Carbon sequestration in soils is a negative emission technology that can contribute to mitigate climate change. However, for European soils, a comprehensive assessment is missing on how much soil organic carbon (SOC) can be sequestered with different management options using also national data on agricultural management.

The aim of CARBOSEQ is thus to estimate the feasible SOC sequestration potential considering technical and economic constraints. The project will align with the current FAO activity for a global SOC-sequestration potential map (GSOCseq).

The key for SOC-sequestration is an enhanced input of biomass (e.g. crop residues) to the soil. for which a new database will be built to facilitate model runs with RothC and other soil SOC models for different management scenarios. The potential area of implementation will be developed together with all partners of CarboSeq and the national expert hubs and all partners will run RothC at national levels.

The final product of CARBOSEQ is the assessment of the European SOC-sequestration potential summarised in an interactive map for Europe. In this map end-users (e.g., stakeholders, or policy makers) can select a set of SOC-sequestration measures along with different target areas, and receive (i) a map that illustrates the amount of additional SOC that could be sequestered by these measures and also (ii) information on potential positive / negative economic / environmental side effects of implementing these measures.

These SOC-sequestration potential maps and data for different management options will guide policy makers regional specific to the most efficient agricultural management options to sequester SOC for climate mitigation.

UMR SAS is involved in WP2 (Crop management), and deputy lead of WP2 Task 6 (Agroforestry on arable land) together with Agroscope. WP2 aims to quantify SOC-sequestration and C-input to the soil effects by cover crops, crops and crops diversification, crop residues, irrigation, reduced tillage as well as hedgerows and agroforestry systems. We will contribute providing input data for assessing the SOC-sequestration potential in agroforestry system across pedo-climatic regions and farming conditions in Europe.
