Greenhouse gas emissions from New Zealand sheep and beef farms

This project aimed to develop a dataset containing animal policies, production efficiencies, and greenhouse gas (GHG) emissions of large number sheep beef farms, examine the relationships between farm management physical constraints, GHG emissions. We used farm-scale model Farmax estimate feed inventories, livestock policies 170 New Zealand farms. Emissions were calculated from outputs using Agricultural Inventory methodology. quantitative approach cluster farms based on constraints attributes. Mean annual biological modelled 3,662 kg CO2 equivalents (CO2-e) per effective hectare, ranged 157 7,096 CO2-e/effective ha. As stocking rate product (wool + net carcass weight) hectare increased, increased. However, there was considerable variability in data; with approximately 4,000 ha had an almost three-fold difference (range 129 360 kg/effective ha). Our work provides holistic assessment drivers comprehensive current state affairs or baseline which future trends can be established.
