Viewshed Analysis-Based Method Integrated to Landscape Character Assessment: Application to Landscape Sustainability of Greenhouses Systems

The visual impact of crop shelters in the rural landscape is paramount importance for sustainability planning. It utmost to protect a beautiful characterized by archaeological sites and natural ecosystems but it also fundamental preserve key economy based on agriculture. To there need understand its units assess feasibility application character assessment (LCA) at local scale adaptation higher scales land-use planning process. In this study, methodology viewshed analysis was integrated into LCA order define areas types. An method done greenhouse systems. Landscape evaluation carried out using both ECOVAST guidelines identification indicators, which were defined computed describe greenhouses. applied study area located South Italy, Province Ragusa, eastern part Sicily, where system highly characterizes agricultural activities made possible guidelines. Finally, visibility map drawn up highlight subject greatest visibility. addition objectifying greenhouses, research verified that proposed LCA-based combined with can be feasible supporting phases urban under new territorial governance laws issued Region Sicily recent years. These analyses useful provide information objectively takes account component context Due limited surface sample considered work should pilot or preliminary study. extension adjacent municipalities could represent practical performed authorities common regulations suitable components.
