2 Two experts responded that actions should be defined by the underfunded actions contained within the Water Quality Improvement Plans for each Natural Resources Management Region. One expert selected actions defined within an existing strategy / plan / initiative than the “Underfunded WQIP (if this option is selected, please provide details below)” and provided the following comment: anthropogenic loads of DIN quoted appear to ignore that from elevated erosion rates (recently identified “The by DSITI project). Anthropogenic PN also contributes a similar or larger amount of N to GBR coastal waters as DIN and so erosion control should be included in the N-reduction activities.” 3.2.3 Costs Abatement of DIN is highly dependent on the region, costing between $44 and $320/ha depending on farm size (State of Queensland, 2016c). Alluvium (2016) recently estimated costs to achieve water quality targets in the Reef region, summarised below.
