In-TIME ha presentato un progetto dal titolo: Discovering buried landfill through a GIS analysis of soil’s morphological changes and of changes in temperature and humidity on earth surface.
Abstract
Buried landfills are a big problem spread in many European countries. The World Health Organization (WHO) stated that in Italy the criminal associations have had an interest in the management of illegal buried landfills.
Therefore it is clear that, while controlled and uncontrolled landfills can be tracked and monitored by local authorities, buried landfills are able to release toxic substances in the ecosystem for an indeterminate period. Then arises the need to study all the possible anomalies that these landfills generate. The procedures of illegal waste disposing have been different over the years, and can be summarized as follows:
- On the beginning of 80’s, the use of abandoned quarries and lakes for the illegal disposal of waste was very frequent; this was verified in previous studies
- At the end of 90’s, the use of areas of territory with an appropriate morphology as an ideal site for the storage of waste and the use of land, in some cases leased ones, through activities of excavation, burying waste with earth over became more frequent
- n recent years, referring to the occurred findings, often occasionally, we saw directly means of transport buried themselves.
In the second half of the 20th century in Italy, the increase of waste production caused an alarming scenario about illegal systems used for waste management. Some regions and provinces have been and are compulsory administrated because of the emergency situation created by improper waste management. One of the earliest cases on this subject was opened by the Public Prosecutor's office in Campania Region in 1980.
The first objective is to investigate the correlation among the variation of soil temperature and moisture and the presence of buried landfills, through optical and SAR data analysis and using a Geographic Information System (GIS) that allows the integration of data and the localization of sites potentially subject to the investigated problem. The GIS will also include ancillary data (geological map, weather stations, rain gauge, etc. ..), databases of Agencies responsible for monitoring landfills (inventory of controlled and uncontrolled landfills, etc.) and some characteristics obtained through ground measurements with specific instruments (TDR and gravimetric system).
The second objective is to investigate the correlation among the variation of soil morphology and the presence of buried landfills, through Differential Interferometry SAR (DInSAR) techniques and a Geographic Information System (GIS) to integrate generated data with specific ancillary data. This will provide a mapping of sites to be subject to detailed checks by the Institution responsible of monitoring.
The total duration of the project is estimated in three years. The key features of the proposing team have multidisciplinary and longstanding experience in the field of remote sensing and spatial analysis through GIS. All team members have extensive experience in large scale analysis and mapping using a GIS and remote sensing data.
