Water quality in sugar catchments of Queensland.

摘要: Water quality condition and trend are important indicators of the impact land use on environment, as degraded water causes unwelcome changes to ecosystem composition health. These concerns extend sea, where discharges nutrients, sediments toxicants above natural levels unwelcome, particularly when they drain Great Barrier Reef World Heritage Area other coastal waters Queensland. Sugarcane is grown in 26 major river catchments Queensland, most environmentally sensitive areas. This puts pressure Queensland Sugar Industry manage ways that have minimum adverse off-site impacts. researchers including CRC been associated with studies North include investigations reviews assess role groundwater a pathway for nitrate loss from canelands Herbert Catchment, find oxygen depletion (including irrigation runoff) Ingham Mackay, residues superseded pesticides sediment assemble information status sugar catchments. Key findings, plus input pressures described this paper, areas concern opportunities discussed.
