La séquestration de carbone dans les sols agricoles, forestiers et urbains : état des lieux des méthodes d’évaluation et de quantification

Abstract : Carbon sequestration, that is, capturing and keeping carbon out of the atmosphere, contributes to climate regulation. In existing classifications (EFESE, CICES), carbon sequestration is defined both as a function of the ecosystem and as an ecosystem service delivered to human societies. For several years, carbon sequestration in soils has been promoted at international and national level in the context of climate change mitigation. Many stakeholders, including cities, farmers and foresters, are in demand for methods to assess, and if possible, quantify this service in the context of their activity. In this article, we inventory the already available and emerging approaches as well as their deployment in forest, agricultural and urban soils. Currently, methods are proposed by researchers to quantify soil organic carbon (SOC) stocks and their stability, predict SOC stocks evolution and estimate the potential for increasing SOC stocks. These approaches are based on direct measurements and/or modeling, and are particularly advanced for agricultural soils. Some of the methods are standardized or in the process of standardization at an international level in order to facilitate their transfer towards professionals (soil laboratory analysis etc.). Nevertheless, it seems necessary to continue the effort to build benchmarks to allow a better interpretation of the results in terms of SOC storage potential or conversely on the estimation of the risk of destocking SOC. This inventory shows that such benchmarks are particularly poorly developed in urban soils. We also discuss the limitations of the methods that call for sustained research and development efforts for the next few years.
