| Abstract: |
The framework for evaluation and assessment of direct and indirect impact of policy using GIS and models allows a wide variety of questions to be asked and reveals a range of possible impacts for consideration. This permits a systematic evaluation of policies and plans and, within the limits of models used, allows a variety of proposals to be compared. Given the role of models in guiding decision-making, the limits of models used need to be made prominent in order that they are not given undue authority and considered a substitute for critical evaluation. Models do, however, provide a form whereby thinking and analysis can be structured and discussion focused. At present there are few models compatible with GIS, and model development is a research priority. Application of GIS in decision-making through the type of analyses described above is below its potential, both because of a lack of suitable models and because of a lack of appropriate databases and restricted use of GIS technology among those directly concerned with decision-making and policy formulation and evaluation. Appropriate systems and models will rely on collaboration between-users and those involved with developing technology. Notwithstanding these constraints, the potential does exist whereby plans and policies can be formulated on the basis of a wide evaluation of their likely consequences. This may lead to the development of a more integrated approach to land use planning and, with appropriate developments in systems and modeling, one which is based on a holistic understanding of environment and human activity. |
