Account-ready data: ecosystem services in the Western Australian Wheatbelt. A data collection from the Regional Ecosystem Accounting Pilot projects

Brief description

This collection comprises account-ready data for the Western Australian Wheatbelt for the following ecosystem services: (1) terrestrial carbon storage, sequestration and emissions and (2) biomass provisioning. Supplementary socio-economic data are also provided. It includes annual time-series provided as spatial data (.GPKG and .TIFF) and Excel spreadsheets.

Terrestrial carbon storage, sequestration and emissions: Spatial emulation of the Full Carbon Accounting Model (FullCAM) is used to develop an annual time-series (1988-2020) of terrestrial carbon storage, sequestration, and emissions across the Western Australian Wheatbelt (WAW) at a spatial resolution of 100 m. Both stocks (carbon mass of crops, pastures, forests, woodlands, shrublands, debris and soil) and fluxes (emissions of CO2, N2O and CH4 due to fire, heterotrophic respiration, net primary productivity, net ecosystem carbon balance) of carbon are provided in units of tCO2e ha-1 and tCO2e ha-1 yr-1, respectively. Emission factors and other quantities used to convert CH4 and N2O fire emissions to CO2e are provided in Section 6.4.5.1 of DISER (2022) (https://www.dcceew.gov.au/sites/default/files/documents/national-inventory-report-2020-volume-2.pdf).

Biomass provisioning: This collection comprises an annual time-series from 2000-01 to 2019-20 (where possible) of physical and monetary measures of agricultural production and estimates of biomass provisioning ecosystem services across the Western Australian Wheatbelt (WAW). The agricultural production data covers crops (fruit and nuts, vegetables, cereal crops, hay, and other crops) and livestock (milk, sheep and lambs, cattle and calves, pigs, poultry). The ecosystem service data provides estimates of the final ecosystem services of crop provisioning and grazed biomass provisioning. The data was sourced from the Australian Bureau of Statistics (ABS) DataLab environment using the Farm-level Longitudinal Agricultural Dataset (FLAD) and the Business Longitudinal Analysis Data Environment (BLADE).

Supplementary socio-economic data: This collection comprises a time series (2011, 2016 and 2021) of selected socio-economic variables across the Western Australian Wheatbelt (WAW). The variables provide estimates of the number of people employed and gross value added (GVA) in selected industries. The data was sourced from the Australian Bureau of Statistics (ABS).
