Grazing

Grazing is the biggest land use in the Great Barrier Reef catchment area occupying 31.1 million hectares of land (73% of the catchment). Grazing lands can be vulnerable to soil erosion and are estimated to contribute 60% of the total load of fine sediment exports to the Great Barrier Reef. […]

What are the most effective management practices (all land uses) for reducing sediment and particulate nutrient loss from the Great Barrier Reef catchments, do these vary spatially or in different climatic conditions? What are the costs and cost-effectiveness of these practices, and does this vary spatially or in different climatic conditions? What are the production outcomes of these practices?
