About wind erosion

In Australia, wind erosion is a serious problem. Our country is the driest inhabited continent on Earth, and is built on an ancient landscape of fragile soils. Together with a 'boom and bust' climate of extremes, our soil resources are easily prone to suffering damage.

When the conditions are such that wind can blow dust, this process of wind erosion is actually a cost to our soil resources. The dust that you see is the fine, light type of soil particles that have dried, become loose and blown away. These fine particles are actually the most important sediments in terms of soil fertility; they contain vital nutrients such as iron, as well as organic matter.

Unfortunately, we can't control where the wind will carry the nutrient-rich dust - sometimes it ends up in the ocean, or other countries.

By minimising wind erosion, we are keeping the nutrient-rich soil particles in the ground and maintaining the best possible soil resources for Australia.
