D4.1 Review of Environmental Models - SEAT Global

2.5 GIS models and the SEAT project
There have been a few studies using GIS as a method of site selection for some of the SEAT
case study species (Hossain et al, 2007; Giap, Yi & Yakupitiyage, 2005); however there has
been a lack of research into using GIS as a tool to measure environmental impact and waste
dispersion with the selected species; the studies that were described previously (Pérez et al
2002; Brooker, 2002; Corner et al, 2006; Tironi, Marin & Campuzano, 2010) all focussed on
Atlantic salmon (Salmo salar). Although aspects of these models can be used with other
species, the environmental conditions and growing requirements vary greatly between
warm/cold water and freshwater/marine/brackish species, consequently new models would
have to be developed. Furthermore, there are differences between each of the case study
species and each species will have different requirements and will vary in the type and
degree of impact therefore models will have to be species specific rather than one model as
that would be too general and would not be representative. New models will be developed
within IDRISI GIS software that will integrate the system dynamics modelling (described in
section 1 of this report) into a spatial setting and also analyse wider field inputs.
