Organic food worse for climate: Study
Organic food has a bigger climate impact than conventionally farmed food, due to the greater areas of land required, according to a study. Researchers from the Chalmers University of Technology in Sweden developed a new method for assessing the climate impact from land-use, and used this, along with other methods, to compare organic and conventional food production. The results, published in the journal Nature, show that organic food can result in much greater emissions. "Our study shows that organic peas, farmed in Sweden, have around a 50 per cent bigger climate impact than conventionally farmed peas," said Stefan Wirsenius, an associate professor at Chalmers. "For some foodstuffs, there is an even bigger difference -- for example, with organic Swedish winter wheat the difference is closer to 70 per cent," Wirsenius said. The reason why organic food is so much worse for the climate is that the yields per hectare are much lower, primarily ...
