The Great Barrier Reef (GBR) catchment contains 997,948 ha (2.33% of the catchment area) of horticulture and
cropping (excluding sugarcane) land which, like all agriculture, has the potential to impact offsite water quality
including the GBR lagoon. Information regarding the extent that commodity-specific activities potentially impact
offsite water quality is periodically updated to inform the design and implementation of on-ground actions within
GBR catchment regions, as well as assist with program and policy decisions. This report finds, collates and
qualitatively synthesises existing knowledge of measured losses of water, sediments, nutrients and pesticides from
horticulture and cropping (excluding sugarcane) within the GBR catchment, and identifies the present gaps in
knowledge that require further consideration.
