Última Energy use in organic farming Organic Eprints Smith, L.G.; Williams, A.G.; Pearce, B.D.. Limited fossil fuel reserves, growing populations and rising input prices highlight the importance of increasing the efficiency of food production systems and reducing GHG emissions. GHG emissions from fossil fuel use in agriculture are important along with the production of CH4 and N2O. In this context, organic agriculture has developed with an emphasis on resource use efficiency. The relative energy efficiencies of organic and non-organic farming were compared through a review of 50 studies including direct on-farm use and embedded energy in inputs. Organic systems use less fossil-fuel energy on a unit of land area basis for nearly all crop and livestock types, although results are more variable per unit of product. In many cases the difference can... Tipo: Conference paper, poster, etc. Palavras-chave: "Organics" in general; Air and water emissions; Environmental aspects.
