“But if the environmental impact is instead calculated on the basis of how much land is required to produce a certain amount of food, well, then we find that organic farming only has a positive effect on biodiversity. Emissions of greenhouse gases and nutrient leakage can even increase if the same amount of food is to be produced with organic instead of conventional agriculture,” Agrifood Economics Centre director Fredrik Wilhelmsson said in a press release.
“We conclude therefore that it is not a given that organic farming is better for the environment than conventional farming. It is thus not self-evident that support for organic farming can be justified on the basis of consideration for the environment. Agricultural subsidies need to be designed to reduce the environmental impact, regardless of whether the cultivation takes place organically or conventionally,” Agrifood Economics Centre researcher Christian Jörgensen concluded.
