ABSTRACT
Sheep are reared under a wide range of conditions globally and in a high diversity of systems ranging from extensive browsing systems through to full housing with brought-in feeds. Additionally, they are often farmed in systems with multiple products including other animals (e.g. beef cattle or goats), arable crops and/or trees. Thus, there is considerable variability in the extent of resource use associated with sheep farming and production of live weight for meat production and wool, as well as in their environmental impacts.
