摘要:Landscape values are addressed by planning tools in several diversified ways. Many European countries have joined the European Landscape Convention which just turned 20 last year. This work aims at investigating its implementations and relationships with general and local planning tools, focusing on two main objectives: the first one concerns the analysis of principles regulating regional strategies, deriving from European dictates and State norms. It has been focused in the Sicily region in Italy, the largest island in the Mediterranean basin. The second objective concerns the in-depth analysis of territories of a fragile nature in which the two terms that characterize the landscape, culture and nature, merge together. This paper consists in gathering information deriving from the various planning levels, proposing a comparison methodology which takes into account physical–environmental and landscape–visual features in some sample cases within protected areas, but in a highly urbanized context. A system and database were created and implemented within the geographic information system, drawing up a comparison between environmental requirements and development strategies.
