Using Spatial Systems To Establish Priorities For Catchment Management, David Deeley, David Weaver, J Hick

Conference papers and presentations

Priorities for catchment management can be established based on either, an objective assessment of relative priorities throughout the catchment, or by simply responding to crises associated with particular land uses and their sectional interests. While the latter method can have advantages in terms of establishing community good will, team cohesion, and a sense of achievement for particular sectional interests, it may have shortcomings in terms of a more objective and rational assessment of the relative magnitude and hence priority of land management problems. Spatial modelling using GIS can form the basis for developing a catchment-wide understanding of the relative importance …
