Abstract / Description of output
First, we identify specific practices with potential for both a positive impact on SCS at farm level, and an uptake rate compatible with global impact. These focus on: a) optimising crop primary productivity (e.g. nutrient optimisation, pH management, irrigation) b) reducing soil disturbance and managing soil physical properties (e.g. improved rotations, minimum till) minimising deliberate removal of C or lateral transport via erosion processes (e.g. support measures, bare fallow reduction) d) addition of C produced outside the system (e.g. organic manure amendments, biochar addition) provision of additional C inputs within the cropping system (e.g. agroforestry, cover cropping) We then consider economic and non-cost barriers and incentives for land managers implementing these measures, along with the potential externalised impacts of implementation. This offers a framework and reference point for holistic assessment of the impacts of SCS. Finally, we summarise and discuss the ability of extant scientific approaches to quantify the technical potential and externalities of SCS measures, and the barriers and incentives to their implementation in global agricultural systems.
