Soil carbon (C ) sequestration implies transferring of atmospheric CO2 into soil of a land unit through its plants. Cobenefits of soil C sequestration include: advancing food and nutritional security, increasing renewability and quality of water, improving biodiversity, and strengthening elemental recycling. Threshold level of soil organic C (SOC) in the root zone is 1.5-2.0%. SOC is influenced by land use, soil management and farming systems. To 1-m depth, more than 50% total C pool is contained between 0.3 and 1 m depth. Soils of agroecosystems are strongly depleted of their SOC stock and are degraded. Restoring soil quality necessitates increasing SOC concentration by adopting best management practices (i.e., conservation agriculture) which create a positive C budget. French Government is proposing to COP-21 of UNFCCC in December 2015 that SOC concentration be increased globally at 4 per 1000 per year to mitigate climate change and advance food security.
