Maribyrnong River

What was included in the economic assessment of Australia's natural resource base?

New data sets have been developed through the National Land and Water Resources Audit that relate to economic aspects of natural resource management in Australia. There is a focus on resources used to support agriculture and resources impacted by agriculture. The Australia-wide report provides:

• An overview of the economic returns from the Nation's land and water resources used in agriculture;
• An agricultural or within pa.gifk perspective on economic aspects of salinity, sodicity and acidity;
• A "beyond the farm gate" perspective on impacts of agriculture on local infrastructure and downstream water users;
• Information on willingness to pay to slow rural population decline and improve environmental attributes that are not part of the market for agricultural products;
• An overview of how the databases developed for this project are organised and observations about ways they can be developed further to assist decision makers.

Consistent with protocols used by the Australian Bureau of Statistics and the Australian Bureau of Agriculture and Resource Economics, the database provides a new capacity to integrate natural resource information in Australia. The data sets are primarily built for the 1996/97 financial year, the year of an agricultural census. Except where stated otherwise, all dollar values given are in 1996/97 dollars.

Most of the data is represented on a 1km by 1km grid covering agricultural land. Whilst modelled at this level of spatial detail interpretation should generally occur at coarser levels. Data on downstream infrastructure costs of deteriorating water quality has been assembled by river basin.
