Abstract
Soil sealing is considered among the most dangerous of land degradation processes on global, European and national scales. Despite importantpolicy documents aiming to mitigate this soil threat, it currently shows no signs of abating, and current efforts often do not result in appropriateimplementation of soil sealing mitigation in spatial planning, which represents the subject area governing soil sealing. In this paper,we show a spatial decision support system - based on a Geospatial Cyberinfrastructure - with the aim of applying it as an operational instrumentaiming towards soil sealing mitigation. The system has the ambition to impact on those who take decision over soil sealing; typically,these are not agriculture experts but rather spatial planners.This tool, focusing on mitigating such crucial land degradation, allows the users - via the Web - to produce 'what-if' land planning scenariosthanks to the 'on-the-fly' modelling engines. Therefore, integrated geospatial quantitative data and procedures may be directly andfreely used by planners.The tool has been applied to and tested in an area in the South of Italy. Results from two applications are reported: one addressing municipalplanning and the other on a more detailed spatial scale. Furthermore, results include quantification of rural fragmentation, loss of soilecosystem services and an estimate of soil sealing evolution over time.The tool was developed with the help of end users and indirectly explores a change of paradigm where soil science and landscape/urbanplanning work together to provide operational instruments that may be adopted by local communities in addressing soil sealing issues with aproactive approach.File | Dimensione | Formato | |
