During 2017/18 the project has:

• Identified two multi-enterprise Māori operations, incorporating dairy, sheep and beef and forestry operations, willing to allow modelling of farm system and land use change to identify impacts of reducing GHG emissions.
• Following discussions with the trustees of the enterprises, carried out a range of modelling involving a range of farm system changes on both the dairy and sheep and beef farms, incorporating improving productivity measures as well as changes in stocking rate and animal production levels.
• Modelling has also incorporated change in land use, particularly increases in forestry development, as well as possible horticulture enterprises, and change in pastoral land uses, e.g. finishing deer, and dairy sheep.

The results of the modelling reinforced previous work that shows changes in farm systems generally have a limited impact on reducing GHG emissions (+/-5-10%) and a variable impact on farm profitability - some reduced farm profitability but those that concentrated on lifting animal performance often resulted in an improvement in farm profitability.
