Country context
Statistical reporting units
Australia usually uses administrative units as their statistical reporting units.
Administrative (admin) units are the geographical areas into which a country is divided. FEWS NET uses the following terminology: National boundary = admin 0, First sub-national division = admin 1 (e.g., states in the United States), Second sub-national division = admin 2 (e.g., counties in the United States), and so on.
Admin 1: States.
Crop data
Crop estimate data sources
The Australian Bureau for Agricultural and Economic Resources Service (ABARES) is the organization charged with evaluating crop production. It publishes 4 Australian Crop Reports per year (March, June, September and December) describing current crop conditions and providing definitive estimates for recent crops, forecasts for current crops, and a running history of crop statistics for each state.
A partner organization working with FEWS NET on this global sub-national agriculture dataset, the Spatial Production Allocation Model (SPAM) activity, managed by IFPRI, has submitted Australian source documents and crop data that have helped to update the country's record of production.
Crop reporting units
Crop data are primarily reported at the admin 1 (state) level, although 2 of the 8 states have not reported their relatively minor agricultural production in recent years.
Admin 1 statistical reporting units are generally divided into either a Northern or Southern region; season dates are referenced by this distinction:
Northern: Northern Territory, Queensland, Western Australia.
Southern: Australian Capital Territory, New South Wales, Southern Australia, Tasmania, Victoria.
Other agricultural reporting is sometimes available at an “SD” (small area) level, but its quality and potentially poor statistical representivity is highlighted by the source org, ABARES.
Year and season definition
Since 1984, the Australian agricultural cropping year runs between October 1 and September 30 (year+1, e.g., October 2023 to September 2024). It is common to refer to Australian cropping years using a two-year notation (e.g., 2018-2019), but if only one year is mentioned, it refers to the first year of the two, as in XXXX/YYYY = XXXX.
add example
Summer
Summer crops in the Northern Region are planted from September to February (year+1), with harvests from February to May.
Summer crops in the Southern Region are planted from October to Dec, with harvests from March to June (year+1).
Winter
Winter crops in the Northern region are planted from March to July, with harvests from September to December.
Winter crops in the Southern Region are planted from May to late July, with harvests from late October to January (year+1).
Methodology
A full description of the crop assessment and forecasting methodology used by ABARES is available in the FEWS NET document management system. It is entitled "The Australian Agricultural Forecasting System (AAFS), ABARES, March 2022.
Apart from cotton, the yield for all other crops is a function of quantity divided by the area harvested.
