Abstract

This paper reviews our current knowledge and understanding on carbon storage in soils under the effect of climate change and land management. For the French metropolitan territory, the carbon storage potential and possible effects of climate change on carbon decrease are of the same order of magnitude. It might be more important to preserve existing large stocks (for example in peat) than to try to create new ones. Whatever the changes are, they will be very difficult to prove within carbon accounting over short periods.
