“Expert system” forenvironmental assessment Elisa Valentini - University of Bologna Michele Sansoni - Environment Agency Emilia-Romagna INPUT 2012 Cagliari,11th May 2012
Goals• Development of a methodology to assess theenvironmental sensitivity of energy systems• Development of sensitivity maps for Emilia-Romagna Region• Support tool useful to facilitate the proceduresof Environmental Impact Assessment (EIA) andStrategic Environmental Assessment (SEA)
Methodology 1a. 1b.Types of plants Sensitivity themes Expert system for environmental 2. Interference rules assessment 3. data Interference matrix models 4. Research of themes 5. Sensitivity maps
Environmental sensitivityEnvironmental sensitivity : “tendency of an environment to beaffected by anthropogenic pressures” Energy facilities and infrastructures Land use Regional and local territorial plans Natural ecosystems …… SENSITIVITY Overlay mapping
1a. Types of plants- Wind farm- Hydroelectric plants- Biomass combustion plants- Fossil fuel power plants- Power lines
1b. Sensitivity themes N. Sensitivity themes 1 Airports 2 Instability areas 3 Archeological areas 4 Methane pipelines 5 Military areas 6 Historical roads system 7 Hill systems 8 Environmental protection areas 9 Crests 10 River basins and rivers 11 Contaminated sites 12 Power lines ….. …………….
2. Interference rules - Themes that represent ties and special preservation defined by law.PURPLE - Very high criticality: maximum level of territorial sensitivity. - Exclusion zone. - Themes that reveal a major inconsistency with the inclusion of the plant; not expressed by specific law but from a technical opinion. RED - High criticality: level of territorial sensitivity very high. -Need more information and careful evaluation of all critical factors involved. -Themes that have a certain incompatibility with the inclusion of the plant.YELLOW - Average criticality: sensitive area. -Critical evaluation of all factors involved: proper plant choices or management could overcome criticalities. - Themes reveal no special exclusion or inclusion of the plant building.WHITE - No criticality: information themes that characterize territorial context. - Themes that are preferential for the building of the plant.GREEN - Preferential zone

4. Research of themes• Research and analysis of databases (Region, ARPA, Provinces, Municipalities, etc…)• Organisation of data with the same common structure• Elaboration of data: geoprocessing and overlay mapping
5. Sensitivity maps• Overlay of the various themes into a single thematic map using GIS• Exclusion areas (PURPLE) prevail on high (RED) and average (YELLOW) attention areas which prevail on attraction (GREEN) areas• “Traffic light maps“ allow to: – have an overview of the ties for the inclusion of a plant in a given site (in particular exclusion areas coherent with regional rules); – identify "feasibility areas“, where it could be possible to build new plants
5. Web GIShttp://servizigis.arpa.emr.it/Geovistaweb/
Conclusions• Analysis of the plan/project area – Identification of sensitivity themes (and ties) and related information• Criticalities framework – Useful for simplifying screening and scoping phases (EIA, SEA) – Identification of critical issues on which focus the monitoring of plan/project – Help in planning phases (and writing of environmental report) and support in making choices between different alternatives• Support in building permissions – Zoning maps: the traffic-light map shows potential exclusion zones, areas of attention and areas which present opportunities for the siting – Link between SEA and EIA
