State of the Environment (SoE) reporting themes
Land
This theme considers the state of our soil and vegetation resources, the pressures they face, and issues and priorities for management.
This chapter provides an account of the most significant and recent human impacts on our land. Our focus is relatively narrow – primarily on land use, vegetation and soil. In particular we focus on the land-management practices and landscape processes that, in the authors’ views, warrant most attention. (SoE 2011, 5 Land - 1.3 In this chapter)
Key findings
SoE 2011:
- Our land use is changing in response to new priorities and new pressures.
- The rate of land clearing, one of the most significant pressures affecting the land environment, averaged around 1 million hectares annually over the decade to 2010.
- Widespread landscape-scale pressures, particularly those due to invasive species and inappropriate fire regimes, continue to threaten environmental values across much of Australia’s land environment.
- Soil processes, including acidification, erosion and loss of soil carbon, will increasingly affect Australia’s agriculture unless they are carefully managed.
- Climate change is expected to bring about profound changes in the Australian land environment, particularly native vegetation and production systems.
- Management effectiveness of the land environment varies.
- Governance and institutional arrangements for management of the land environment need improvement, and levels of investment are inadequate.
- There is a serious capacity gap in the professional and technical human resources necessary for effective land management, including both a growing shortage of qualified people and a lack of relevant skills and experience among the next generation of land managers.
- The outlook for Australia’s land environment is mixed.

SoE 2006:
- At the national level, the rate of vegetation clearing has decreased in recent years in many states.
- Sheep and cattle grazing derives high economic value for Australia but, in doing so, continues to place heavy pressures on soils, vegetation, and terrestrial and wetland habitats, especially in sensitive areas.
- The ongoing decline in soil quality is of concern.
- The need to take a landscape-wide view of land and vegetation management is increasingly being recognised by governments, regional management groups and farmers.
- The regional NAP and NHT programmes remain important in funding and guiding catchment and bioregion-based planning and management actions.
