368 | Water resource assessment for the Mitchell catchment 7 Ecological, biosecurity, off-site and irrigation- induced salinity risks Authors: Carmel Pollino, Andrew Ash, Brendan Ebner, Tony Grice, Simon Irvin, Rob Kenyon, Linda Merrin, Daryl Nielson, Jackie O'Sullivan, Dean Paini, Jeda Palmer, Cuan Petheram, Danial Stratford, Andrew R Taylor and Mark Thomas Chapter 7 discusses a range of potential risks to be considered before establishing a greenfield agriculture or aquaculture development. These include the ecological implications of altered flow regimes, a range of biosecurity considerations, off-site impacts from sediments, nutrients and agropollutants, irrigation drainage and aquaculture discharge water and irrigation-induced salinity. The key components and concepts of Chapter 7 are shown in Figure 7-1.
