Turning the tide on reef water quality
Evidence of coastal ecosystem degradation in the Great Barrier Reef has been linked with increased land-based runoff of suspended solids, nutrients and pesticides resulting from clearing and agricultural land use.
The long term survival of Australia’s world heritage listed Great Barrier Reef is under threat from various pressures including declining water quality in the reef lagoon. Pollutants such as sediment, nutrients, and pesticides in waters that flow from agricultural lands in the catchments adjacent to the reef have been found to be the major cause of the decline.
In an effort to combat this, CSIRO is conducting research in the Great Barrier Reef region to ensure the long term protection and restoration of reef ecosystems, and the sustainability of agricultural land uses.
