Organic agriculture stores more carbon in the soil than conventional agriculture. It has fewer greenhouse gas emissions than conventional agriculture because it doesn’t use fossil fuel-intensive pesticides or fertilizers. Its combination of expanded soil fertility and flexible crop rotations make it more adaptable to the effects of climate change and, in the case of developing countries, may be better suited to produce more food. These are the conclusions of a new paper by the UN Food and Agriculture Organization, titled Organic Agriculture and Carbon Sequestration.
The FAO researchers also point out that the precise measuring of carbon sequestration for agriculture is not well developed. This is a problem for those pushing for carbon accounting standards that would designate agriculture as an offset market for polluters (IATP has been critical of this approach), and why most existing carbon-accounting systems do not consider agricultural carbon sequestration. Those carbon-accounting systems that do consider sequestration do not adequately consider the full contributions of organic agriculture, according to the FAO paper.
Despite these clear advantages, organic agriculture continues to be on the outside looking in when it comes to climate policy. At the global climate talks in Copenhagen, the new Global Research Alliance on Agricultural Greenhouse Gases emphasized the development of new technologies for agriculture. Organic agriculture wasn’t mentioned. It’s easy to be cynical about this: organic practices are knowledge-based, versus techno fixes that are patent-based and benefit agribusiness companies.
Over the next four years, the U.S. Department of Agriculture expects to invest $320 million in climate change mitigation and adaptation research for agriculture. The USDA should read this new FAO report and make sure that organic agriculture has a prominent place on its research agenda.
