Low emissions farm systems for the Māori sector
This project aims to improve the capacity of Māori farmers to improve their efficiency and productivity while lowering greenhouse gas emissions.
Two Māori agri-business entities involving dairy, sheep and beef, forestry and horticulture are having their GHG emissions modelled including looking at how these emissions and profitability can be balanced at a business level.
In addition, the project investigates decision-making criteria and issues around introducing new GHG mitigation strategies and analyses any barriers to the uptake of such strategies.

What is OVERSEER?
The most well-known calculator for estimating GHG emissions in farm is using is the nutrient budgeting tool OVERSEER®.
This uses nitrogen inputs and outputs, as well as the number and productivity of animals, to calculate the unique nutrient budget of a farm, and makes broad inferences from nutrients to greenhouse gases using simplified relationships.
OVERSEER® can only provide an approximate farm-level greenhouse gas assessment, since it does not fully reflect all the variables that can affect the unique greenhouse gas budget of a farm (e.g. the specific soil moisture profile and microclimate on the farm).
