Integrated Catchment Management

Output from IDEAS

A successful workshop was held in Nelson in February 2009 with ICM researchers and Tasman District Council exploring how the IDEAS modelling framework operates as well as discussing elements of the individual models that contribute to IDEAS. The "loose coupling" approach of IDEAS was explained by John Dymond who also talked about the central data link in which outputs from models are used as input for others.

The scenarios modelled to date include a pre–historic land cover in which the catchment was covered in native forest, present day land use, and an intensive land use in which dairying and other agriculture was expanded into areas currently in production pine forest. In these scenarios different levels of environmental effects such as for example, nitrogen export and faecal contamination which in turn will affect productivity in Tasman Bay and ultimately the number of jobs derived from aquaculture.

IDEAS will continue to be refined as part of on–going and future work.
