A new evaluation scheme, land management within capability (LMwC), used to guide sustainable land management in New South Wales (NSW), is presented. The scheme semi-quantitatively categorises the potential impacts of specific land-management actions and compares these with the inherent physical capability of the land in relation to a range of land-degradation hazards. This leads to the derivation of LMwC indices, which signify the sustainability of land-management practices at the scale of individual sites up to broader regions. The LMwC scheme can be used to identify lands at greatest risk from various land-degradation hazards. It can help to guide natural resource agencies at local, regional and state levels to target priorities and promote sustainable land management across their lands. Few other schemes that assess the sustainability of a given land-management regime in a semi-quantitative yet pragmatic manner are found in the literature. The scheme has particular application for regional soil-monitoring programs and it was applied in such a program over NSW in 2008–09. The results suggested that the hazards most poorly managed across the state are wind erosion, soil acidification and soil organic carbon decline. The LMwC scheme, or at least its underlying concepts, could be readily applied to other jurisdictions.

Initial Objective

There is a widespread and growing need for information relating to soil condition and changes in response to land management pressures. To provide the information needed to quantify land management effects on soil condition, monitoring systems are now being put in place and these programs will generate large numbers of samples. Streamlined procedures for the analysis of large sample numbers are therefore required. Bulk density (BD) is considered to be one of several key indicators for measuring soil physical condition, and is also required to estimate soil carbon density. The standard analytical technique for BD requires drying the soil at 105°C but this procedure creates several logistical and analytical problems. Our initial objective was to derive correction factors between drying temperatures to allow for rapid, low-temperature estimation of BD on large sample numbers. Soil samples were collected from 3 contrasting soil types (basalt, granite, and meta-sediments) in 4 land uses (cultivation, sown pasture, native pasture, woodland) in northern New South Wales to test the effect of soil drying temperature on BD determination. Cores were divided into 4 depths (0–0.05, 0.050–0.10, 0.10–0.20, 0.20–0.30 m), and oven-dried at 40, 70, and 105°C. Drying temperature had no significant effect on BD but the effects of soil type, depth, and land use were significant, varying according to expectations based on previous studies, i.e. higher BD in granite-derived soils and lower in basalt-derived soils, increased BD with depth, and increasing BD with increasing management intensity. These results indicate that lower drying temperatures (40°C) were adequate for the efficient determination of BD especially where analysis of other soil properties from the same sample is required. However, before this approach is applied more widely, further calibration of BD and drying temperature should be undertaken across a wider range of soils, especially on clay-rich soils.

The University

The extensive and radical change in pastoral land treatment and management which has taken place on the Northern Tablelands of New South Wales since 1950 has greatly increased the demand on available water, and has at the same time affected the amount and rate of water run-off into streams and dams, and the nature and permanency of springs and streams. This has not only created problems of water scarcity on the Tablelands, but it has serious implications for the Darling River system, of which the Tablelands form a major source of supply, because of reduced run-off into headwater streams, and additional retention of water for livestock in larger, and an increased number of, farm dams. The onset of drought in 1980 precipitated an immediate and serious shortage of water for livestock and urban use. A recognition that this was partly man induced led to the establishment of a Water Management Research project, jointly sponsored by land users and the University of New England. In 1981-2 a detailed study was undertaken of a typical Tablelands area, the Severn River basin, to ascertain and quantify the effects of changed land management. The results of the study, its implications, and conclusions drawn from it are discussed.

Indigenous Land

My PhD research focuses on the manifestations of Aboriginal relationships to land in New South Wales. My research at first was very much centered on the specific issue of Aboriginal ‘involvement’ in five newly nominated Aboriginal owned national parks to be jointly managed with the NSW National Parks and Wildlife Service under the National Parks and Wildlife (Aboriginal Ownership) Amendment Act (NSW) 1996.
