Catchment scale land use of Australia – Update December 2020
Publication date: 25 February 2021
This dataset is the national compilation of catchment scale land use data for Australia (CLUM), as at December 2020. It replaces the Catchment Scale Land Use of Australia – Update December 2018. 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. It has been compiled from vector land use datasets collected as part of state and territory mapping programs through the Australian Collaborative Land Use and Management Program (ACLUMP). Catchment scale land use data was produced by combining land tenure and other types of land use information, fine-scale satellite data and information collected in the field. The date of mapping (2008 to 2019) 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 a supporting dataset.
The following areas have been updated since the December 2018 version: Burnett Mary and Fitzroy natural resource management (NRM) regions in Queensland; Sydney basin in New South Wales; the state of Tasmania; and the Darwin–Litchfield and Katherine areas in Northern Territory.
The CLUM data shows a single dominant land use for a given area, based on the 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 (ALUM) Classification Version 8, 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 Catchment Scale Land Use of Australia – Update December 2020 is a product of the Australian Collaborative Land Use and Management Program (ACLUMP). ACLUMP, a consortium of Australian, state and territory government partners, promotes the development of nationally consistent information on land use and land management practices underpinned by common technical standards.
A complementary dataset Catchment Scale Land Use of Australia – Commodities – Update December 2020 provides commodity level mapping, where available, as a vector dataset.
