Organic farming uses less energy than conventional agriculture to produce the same quantity of food
For[edit | edit source]
- According to Our World in Data, "The absence of synthetic chemical inputs in organic systems therefore means that their energy use is predominantly lower than in intensive conventional agriculture." In a meta-analysis of results of published organic-conventional comparisons across 742 agricultural systems over 90 unique foods, energy use was found to be lower in organic methods in 4 of 5 food groups studied. The researchers Clark and Tillman found that "organic systems use 15% less energy (p = .0452; n = 33 ... than conventional systems per unit of food."
Against[edit | edit source]
- According to Our World in Data, "The exception to this result is vegetables, for which energy use in organic systems tends to be higher. Some of this additional energy use is explained by the use of alternative methods of weed and pest control in organic vegetable farming; a technique widely applied as an alternative to synthetic pesticide application is the use of 'propane-fueled flame weeding'. The process of propane production and machinery used in its application can add energy costs - especially for vegetable crops."
