Description: This dataset estimates the location and mass in dry tonnes at 0% moisture content (MC) and in tonnes at post-milling 14% MC of rice hull residues across NSW, Australia. This information was originally collated for the Australian Biomass for Bioenergy Assessment (ABBA) project and has been updated several times. It is available for use in the NSW BioSMART tool (Biomass Spatial and Modular Assessment of Resources Tool - https://www.dpi.nsw.gov.au/forestry/science/forest-carbon/biomass-for-bioenergy/nsw-biosmart) and on the National Map (https://nationalmap.gov.au/) platform. The boundary features were extracted from the Australian Bureau of Statistics (ABS) Australian Statistical Geography Standard (ASGS 2016) digital boundaries [Copyright Commonwealth of Australia administered by the ABS]. This dataset is mapped at the Statistical Area Level 2 (SA2). Each SA2 region shows the annual average tonnes of rice hull residues post-milling for the period July 2011 to June 2021 (average of 10 years). The SA2 residues were derived using the ‘parent’ SA4 region residue totals (calculated using ABS ASGS Agricultural Commodities, Australia, cat. no. 7121.0 data cubes and from research carried out by the NSW Forest Science unit, Department of Primary Industries and Regional Development - Forestry) and by applying calculated percentages of each crop production from the ABS 2015-16FY SA2 agricultural survey data to determine the distribution of residues at this level. Please note the location of residues for the SA2 maps is based on the 2015-16FY crop production distribution (and in some cases the 2020-21FY crop production distribution). Also, the location of mills was taken into consideration and all rice mills occur within the same regions as the crop was grown. The SA4 residue totals were calculated using information gathered from literature and industry contacts (DPI and SunRice) which indicate that the rice hulls account for approximately 20% of the paddy weight and the MC is approximately 14% at milling time. Note: Some SA2 regions were merged and the results were combined. Most commonly merged regions were built up areas contained wholly within the same regional area (i.e. Goulburn and Goulburn Region were merged). Some small regions along the coast were also merged with adjacent regions for clearer mapping.
