Greenhouse gas emissions and resource efficiency of cattle husbandry

Agriculture is responsible for 10 to 12% of anthropogenic greenhouse gas (GHG) emissions worldwide. In respect to N2O and methane (CH4) agriculture contributes around 58% and 47% of the emissions, respectively. Highest drivers of GHG emissions in the European Union are nitrogen fertilizer production and animal husbandry, the latter mainly through CH4 emissions. The impact of farming systems (organic vs. conventional) and intensity levels (low-input vs. high-input) are contentious issues. Aim of the research is the improvement of sustainability in organic dairy farming based on a solid animal health, consistent high yields while maintaining an efficient resource use and low environmental impact.
