Organic farming - worse for the climate

From the MIT Technology Review:

Sorry—organic farming is actually worse for climate change
Organic practices can reduce climate pollution produced directly from farming – which would be fantastic if they didn’t also require more land to produce the same amount of food.

Clearing additional grasslands or forests to grow enough food to make up for that difference would release far more greenhouse gas than the practices initially reduce, a new study in Nature Communications finds.

Other recent research has also concluded that organic farming produces more climate pollution than conventional practices when the additional land required is taken into account. In the new paper, researchers at the UK’s Cranfield University took a broad look at the question by analyzing what would happen if all of England and Wales shifted entirely to these practices.

The upshot is that you get a 5% reduction in "greenhouse gasses" with livestock and a 20% reduction with crops but organic farming is less efficient in terms of land use so you need to use 40% more land for the same food. Your gains are wiped out.
