Multifactor sensitivity assessment
for spatial planning in Izmir, Turkey
Sensitivity assessment produces data to guide spatial planning by determining areas that need to be protected. Izmir,
the study area of this article, is a city with rich ecological
values but rapidly changing spatiality. This study determines ecologically sensitive areas of Izmir and reveals the
relationship between ecologically sensitive areas and spatial planning decisions. To achieve this goal, ecologically
sensitive areas are defened by the Analytical Hierarchy
Process (AHP) and overlapped with planning decisions.
The study evaluates ecological factors and processes using
nine main parameters and twenty-one sub-parameters.
Each of the parameters selected was divided into ecological sensitivity levels. The result of the analysis found
16.8% of the area to have very high sensitivity, 18.5%
high sensitivity, 22.7% average sensitivity, 28.5% low sensitivity, and 13.5% very low sensitivity. A comparison of
these areas with the 1:100,000 Environmental Regulation
Plan decisions showed that the planning decisions are not
compatible with the ecological sensitivities of the study
area. As a result, the study provides an ecological sensitivity assessment model that can contribute to improving
decision-making processes in urban plans.
