Catchment Scale Land Use 2023, Simplified Classification

Abstract Catchment Scale Land Use of Australia (CLUM), depicted as 19 simplified land use classes based on the simplified classes of the Australian Land Use and Management (ALUM) Classification version 8. The classes are Nature conservation, Managed resource protection, Other minimal use, Grazing native vegetation, Production native forests, Grazing modified pastures, Plantation forests (commercial and other), Dryland cropping, Dryland horticulture, Land in transition, Irrigated pastures, Irrigated cropping, Irrigated horticulture, Intensive horticulture and animal production, Rural residential and farm infrastructure, Urban residential, Other intensive uses, Mining and waste, and Water. [Catchment Scale Land Use - Simplified] The Catchment Scale Land Use of Australia – Update December 2023 version 2 dataset is the national compilation of catchment scale land use data available for Australia, as at December 2023. It replaces the Catchment Scale Land Use of Australia – Update December 2020. It is a seamless raster dataset that combines land use data for all state and territory jurisdictions, compiled at a resolution of 50 metres by 50 metres. The CLUM data shows a single dominant land use for a given area, based on the primary management objective of the land manager (as identified by state and territory agencies). Land use is classified according to the Australian Land Use and Management Classification version 8. It has been compiled from vector land use datasets collected as part of state and territory mapping programs and other authoritative sources, through the Australian Collaborative Land Use and Management Program. Catchment scale land use data was produced by combining land tenure and other types of land use information including, fine-scale satellite data, ancillary datasets, and information collected in the field. The date of mapping (2008 to 2023) and scale of mapping (1:5,000 to 1:250,000) vary, reflecting the source data, capture date and scale. Date and scale of mapping are provided in supporting datasets.

ABARES is providing this data to the public under a [Creative Commons Attribution 4.0] license. Lineage statement ABARES has produced this raster dataset from vector catchment scale land use data provided by state and territory agencies, as follows: * Catchment Scale Land Use Mapping for the Australian Capital Territory 2012 * 2017 NSW Land Use v1.5 * Land Use Mapping Project of the Northern Territory, 2016 – 2022 (LUMP) * Land use mapping – 2021 – Great Barrier Reef NRM regions * Land use mapping – 1999 to Current – Queensland (June 2019) * [South Australia] Land Use (ACLUMP) (2017) * Tasmanian Land Use 2022 * Victorian Land Use Information System [VLUIS] 2021-22 * Catchment Scale Land Use Mapping for Western Australia 2018 * Australian Tree Crops, Australian Protected Cropping Structures and Queensland Soybean Crops maps (as at 30 November 2023) * Applied Agricultural Remote Sensing Centre (AARSC), University of New England. Links to land use mapping datasets and metadata are available at the ACLUMP data download page at [agriculture.gov.au]. State and territory vector catchment scale land use data were produced by combining land tenure and other types of land use information, fine-scale satellite data and information collected in the field, as outlined in 'Guidelines for land use mapping in Australia: principles, procedures and definitions, 4th edition' (ABARES 2011). The Northern Territory, Queensland, South Australia, Tasmania, Victoria and Western Australia were mapped to version 8 of the ALUM classification (‘The Australian Land Use and Management Classification Version 8’, ABARES 2016). The Australian Capital Territory was mapped to version 7 of the ALUM classification and converted to version 8 using a look-up table based on Appendix 1 of ABARES (2016). The following agricultural (excluding intensive uses) classes were included from the Queensland Great Barrier Reef NRM Regions 2021 modified ALUM classification schema dataset: * 2.2.0 Grazing native vegetation * 3.2.0 Grazing modified pastures * 3.3.0 Cropping * 3.3.5 Sugar * 3.4.0 Perennial horticulture * 3.4.1 Tree fruits * 3.5.0 Seasonal horticulture * 3.6.0 Land in transition * 4.2.0 Grazing irrigated modified pastures * 4.3.0 Irrigated cropping * 4.3.5 Irrigated sugar * 4.4.0 Irrigated perennial horticulture * 4.4.1 Irrigated tree fruits * 4.5.0 Irrigated seasonal horticulture * 4.6.0 Irrigated land in transition Fixes to known issues include: * In Western Australia, ALUM classes 4.0.0 Production from Irrigated Agriculture and Plantations, 5.0.0 Intensive Uses and 6.0.0 Water have been attributed to secondary level by visual interpretation using satellite data. * In South Australia, through consultation with the South Australian Department of Environment and Water, the mining area (ALUM class 5.8.0 Mining) within mining tenements is more accurately delineated. The area within mining tenements that is not used for mining is now attributed as grazing of native vegetation (ALUM class 2.1.0) within pastoral areas and residual native cover (ALUM class 1.3.3) outside of pastoral areas. NODATA voids in Adelaide, South Australia were filled with data from mesh block land use attributes (Australian Bureau of Statistics 2021) according to Table 8. All other NODATA voids were filled using the ESRI ArcGIS focal statistics command. For the purposes of web viewing, the data was reprojected to EPSG:3857 - Web Mercator. Land use classification The Australian Land Use and Management (ALUM) Classification version 8 is a three-tiered hierarchical structure. There are five primary classes, identified in order of increasing levels of intervention or potential impact on the natural landscape. Water is included separately as a sixth primary class. Primary and secondary levels relate to the principal land use. Tertiary classes may include additional information on commodity groups, specific commodities, land management practices or vegetation information. The primary, secondary and tertiary codes work together to provide increasing levels of detail about the land use. Land may be subject to concurrent uses. For example, while the main management objective of a multiple-use production forest may be timber production, it may also provide conservation, recreation, grazing and water catchment land uses. In these cases, production forestry is commonly identified in the ALUM code as the prime land use.
