Le programme GESSOL 2 : impact des pratiques agricoles sur les matières organiques et les fonctions des sols

Abstract : It is accepted unequivocally, that the non-renewable soil heritage, on a scale of human generations, imposed to preserve soils and eco- system services they provide, such as food production and biomass, regulation and filtering water, mitigation and adaptation to climate change, conservation of biodiversity. In 1998, the Ministry for the Environment has set up the program GESSOL (acronym built from the words “gestion” and “sol”, i.e. respectively management and soil”, the full title of the programme being “Environmental functions of soils - Management of the soil heritage”). In France, GESSOL is the first and only program of research specifically devoted to soils and their functions as a whole. The second call for research proposals, launched in 2003, known as GESSOL-2, concerned the “impact of agricultural practices on soil and water, and transfers of pollutants to water systems”. Among the project financed by GESSOL-2, soil organic matter (SOM) have emerged as the main unifying theme, in particular, when concerning the research axis on “the influence of agricultural practices on soil quality and modalities of sustainable management”. The programme GESSOL-2 has funded six projects related to SOM and involving different regulation services concerning risk, disease, erosion, and climate. In this thematic issue of Etude et Gestion des Sols, those projects are subject to detailed articles presenting the main results. The next step of GESSOL, initiated in 2008, aims to put these results in relation with human and social aspect to better showcase the many services provided by soils through the diversity of their functions.
