41. A GIS-BASED MULTI-CRITERIA MODEL FOR THE SUSTAINABLE MANAGEMENT OF GRAZING IN NATURAL PROTECTED AREAS. AN APPLICATION IN THE ASPROMONTE NATIONAL PARK
The present research was aimed at defining a GIS-based multi-criteria model working as a Spatial Decision Support System (SDSS) for the sustainable planning of grazing resources in the Aspromonte National Park (Calabria, Italy). The method of evaluation adopted is characterised by a multi-criteria approach, allowing the realization of thematic maps of land suitability (LS) for grazing. LS was evaluated and classified according to different domestic animal species, on the basis of a characterization of the main land features influencing it, and of the quality and availability of forage (both in quantitative terms and depending on seasons). Subtractive masking, overlaying maps representing limitations and constraints for grazing, allow to single out, from among the suitable areas, those where grazing can be carried out. In order to support decisions in the planning and management process, the model was refined so as to select grazing areas of sufficient extension (equal of superior to a fixed value), resulting from the combination of contiguous land units with satisfactory suitability. The model can easily be updated and can effectively support a Grazing Management Plan. Although implemented and tested for application in a specific park, it can be extended to other Mediterranean regions where stock raising has great importance in the local economy.
