While organic agriculture has long been hailed as key to building a sustainable food system, a new study pinpoints the critical role that it could play in combating climate change. In a meta-analysis of over 4,000 studies, researchers found that best management organic farming practices could lead to a significant double-digit increase in the amount of carbon captured in soil.
Organic farmers could be amplifying their positive climate impact by adopting the best agricultural practices to boost carbon sequestration. The study, undertaken by scientists at the University of Maryland in collaboration with Washington D.C.-based nonprofit research organisation The Organic Center and published in the journal Agriculture, Ecosystems and Environment, found that the amount of carbon captured in soil increased by 18%, while the amount of microbial biomass carbon storage went up by 30%.
Over 4,000 scientific articles were included in the meta-analysis led by Professor Kate Tully and Dr. Rob Crystal-Ornelas to identify the specific carbon-building techniques that farmers could implement.
