This seminar confirmed that less greenhouse gas (GHG) is emitted per unit area under organic agriculture than under conventional agriculture, and that our eating patterns have a strong impact on factors involved in climate change. Moreover, it shed new light on and contributed original information to a variety of fields. The two major advantages of organic farming in terms of the mitigation of GHG emissions are its ability to store carbon in the ground and the non-use of synthetic nitrogen fertilisers. Means for improving practices and research priorities were identified
