A Geodesign Approach for Using Spatial Indicators in Land-use Planning

This paper presents an original approach to Strategic Environmental Assessment (SEA) for supporting decision-making processes in Local Land-Use Planning (LLUP) which integrates a set of frameworks and methodologies into technologies based on the use of Geographic Information. The technologies embrace the domain of Planning Support Systems (PSS), whose architecture is based on the Geodesign framework. The structure of the Planning Support System includes spatial indicators frameworks rooted on the Driving Force-Pressure-State-Impact-Response (DPSIR) framework. The spatial DPSIR model allows dealing with common issues in spatial planning, such as collaborative and participative decision-making processes, informed alternative design, real-time impact assessment and environmental reporting. Furthermore, the planning support system may foster the widespread diffusion of innovations in the planning domain reeling on the availability of Spatial Data Infrastructures. The study aims at investigating the efficiency of this approach integrated into SEA-LLUP based on the results of a case study developed in Sardinia (Italy).
