Takahuri Whenua GHG modelling Report

This project focuses on three Māori Collectives, and investigates: 

• (i)  The impact on greenhouse gas emissions, farm profitability, and nitrogen leaching levels at an individual farm level for six farms within each Collective;
  
• (ii)  The opportunity to operate the farms at a Collective level to enhance greenhouse gas emission reductions while maintaining or improving profitability; and
  
• (iii)  The opportunity to operate at a pan-Collective level to further achieve the goals of reduced greenhouse gas emissions/maintenance of business profitability.
  

This report concentrates on the first objective, namely the modelling at the individual farm level. 

The three Collectives were: 

• (i)  Tuwharetoa Farming Collective (Central North Island/Taupo) – sheep & beef farms
  
• (ii)  Te Arawa Arataua (Bay of Plenty/Rotorua) – dairy farms
  
• (iii)  Whāngārā Partnership (East Coast) – sheep & beef farms
  

All the individual farms were visited, and discussions held with Governance and management as to greenhouse gas issues, likely scenarios to be modelled, and best opportunities within the farm as to land use change. 

The modelling involved three distinct aspects; farm system change, land use change into forestry, and land use change into either arable cropping or permanent horticulture. 

The details of the modelling for each farm are outlined in the report. A summary of the results are available to download in the report.
