| Results are presented of a model study comparing energy use and greenhouse gas emissions in organic and conventional farming systems in the Netherlands. Calculations have been performed for model farms, designed on the basis of current organic and conventional farming practices. Energy use and greenhouse gas emissions per hectare on organic farms are lower than on conventional farms, particularly in dairy farming. Energy use and greenhouse gas emissions per Mg of milk in organic dairy farming is about 80 and 90%, respectively of that in conventional dairy farming. Energy use and greenhouse gas emission per Mg product in organic crop production is 5-40 and 7-17%, respectively higher than in conventional systems. The wide ranges found in crop production... |

| Herbivores are a significant source of nitrous oxide (N2O) emissions. They account for a large share of manure-related N2O emissions, as well as soil-related N2O emissions through the use of grazing land, and land for feed and forage production. It is widely acknowledged that mitigation measures are necessary to avoid an increase in N2O emissions while meeting the growing global food demand. The production and emissions of N2O are closely linked to the efficiency of nitrogen (N) transfer between the major components of a livestock system, that is, animal, manure, soil and crop. Therefore, mitigation options in this paper have been structured along these N pathways. Mitigation technologies involving diet-based intervention include lowering the CP content... |
