Accounting for multi-functionality of sheep farming in the carbon footprint of lamb: A comparison of three contrasting Mediterranean systems.

摘要: Abstract Intensifying animal production is generally advocated to mitigate greenhouse gases emissions associated with of animal-source food. Sheep farming systems (SFSs) in Spain are considered be pasture-based and extensive, but large differences input utilization, land use intensification level exist. Their environmental impacts, therefore, expected differ also. We used life cycle assessment (LCA) evaluate (GHGs) three contrasting meat-sheep Spain, which differed their degree (reproduction rate, grazing management). The GHGs these varied from 19.5 25.9 kg CO 2 -eq per kg lamb live weight, or 39.0–51.7 kg CO meat, highest values referring the livestock system. In addition however, SFSs also provide other services society (e.g. public goods such as biodiversity landscape conservation). valued for each based on agri-environmental subsidies EU farm economic allocate between meat cultural ecosystem services. When accounting multifunctionality, emission weight among was reversed: lowest system (13.9 kg weight) zero-grazing (19.5 kg weight). A comparison should account multifunctionality systems.
