Why map soils and landscapes?
We map soils and landscapes to understand:
- their attributes and distribution
- the processes by which they develop
- their capability and suitability for various uses
- what risks may be involved and how they can be safely addressed.
Soil information is important for both the direct users of land and soils and for more strategic purposes, such as planning and policy-making and environmental protection. It is also important for the improvement of or adaptation to large-scale environmental problems such as climate change, soil erosion, acidification and dryland salinity.
Agriculture and food security is another important area where soil information matters, not only for human health and food security but for the health of the economy. In 2014-15 NSW delivered approximately $12.125 billion in agricultural production, all of which was reliant in some way on the soil. As an example, soil and landscape mapping provides the foundation for the mapping of NSW’s best land and soils as Biophysical Strategic Agricultural Land.
