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 because fertilisers are not used. Read
