Potatoes - economic indicators

Description

Estimates of the Adjusted Yield, Revenue, Expenses, Operating Profit, Labour, and regional flow on impacts (GDP, Household income, and Labour) associated with a land use in a location.

These are based on the Plant and Food Research (PFR) estimates of crop suitability and production. Expenses updated to 2023 using Arable sector Producer Price Index adjustment (StatsNZ)

Methodology

Data is based on industry data and reports. Expenses updated to 2023 using business price index (StatsNZ).

Agribusiness Group yield was changed to industry national average yield. Plant and Food Research (PFR) estimates of yield were used to adjust the national average yield to individual locations using a ratio of the average of PFR yield for the most suitable (suitability category 1) locations to the national average yield.

This adjusted yield was used to estimated revenue, variable expenses and variable labour requirements for each location. From these the total revenue, expenses, operating profit and on farm labour costs were calculated. FTE per 10 ha was calculated using a standard cost of $52,345/FTE.

These data points were used to generate estimates of direct (on farm) gross domestic product (GDP), household income (HHI), and employment (FTE per 10 ha). Multipliers from a regional IO table were used to calculate the indirect and induced effects of the expenditure and houshold income, which was added to the direct estimates to generate a Total GDP, Total HHI, and Total FTE/10 ha.

 

Fitness for purpose / limitations

This table indicates whether the dataset is suitable for different types of questions at different scales.

Note: Users should carefully consider their purpose as this dataset may not be suitable.

Operational Absolute Relative Screening/scoping
Block/farm No No No Maybe
Multi-farms(5+) No No No Yes
Catchment No No Maybe Yes
National/regional No Maybe Yes Yes
Caveat(s) Data based on information supplied by Agribusiness Group from a limited number of growers. Yield was adjusted by scaling from the Fresh Fact 2020 data on yield distribution between fresh and process potatoes. This was used to adjust the process potato yield data supplied by the Agribusiness Group.
