L’initiative 4 pour 1000 a \u00e9t\u00e9 \u00e9labor\u00e9e par des chercheurs de l\u2019Inra \u00e0 la fin du XXe si\u00e8cle pour restaurer la fertilit\u00e9 de sols et pi\u00e9ger des gaz \u00e0 effet de serre.<\/p>\n
Leur calcul est simple : les sols constituent au niveau mondial le premier stock de carbone biologique \u2013 si l\u2019on exclut les oc\u00e9ans et les roches s\u00e9dimentaires. En captant du CO2 de l\u2019air via la photosynth\u00e8se, une plante absorbe du carbone. Si cette plante se d\u00e9compose dans le sol, elle lui restitue son carbone sous forme de mati\u00e8re organique. Le sol s\u2019enrichit alors de carbone, et devient plus fertile, plus r\u00e9silient.<\/p>\n
