An Assessment of the Effectiveness of Strategic Spatial Planning: A Study of Sardinian Municipalities

A political and technical debate about the effectiveness of strategic spatial planning results is ongoing. The debate has taken this direction, rather than focusing on the methods, procedures and organization of spatial planning, because it is difficult to contextualize the development of programmed steps within the time required for their implementation. This article explores the potentialities and challenges of this debate, focusing on its evolutionary excursus in Italy and the region of Sardinia. The aim of this article is to propose a qualitative assessment methodology, capable of comparing different spatial strategic plans, in order to understand the extent to which the plans’ stated objectives were achieved, and to assess what changes the implementation of these objectives achieved in the external environment over the medium and long term.
