“Expert system” for
environmental assessmentenvironmental assessmentElisa Valentini - University of Bologna
Michele Sansoni - Environment Agency Emilia-Romagna
INPUT 2012
Cagliari,11th May 2012
Goals
• Development of a methodology to assess the
environmental sensitivity of energy systems
• Development of sensitivity maps for Emilia-• Development of sensitivity maps for Emilia-
Romagna Region
• Support tool useful to facilitate the procedures
of Environmental Impact Assessment (EIA) and
Strategic Environmental Assessment (SEA)

Environmental sensitivity
Environmental sensitivity : “tendency of an environment to be
affected by anthropogenic pressures”

SENSITIVITY
1a. Types of plants
- Wind farm
- Hydroelectric plants
- Biomass combustion plants- Biomass combustion plants
- Fossil fuel power plants
- Power lines
1b. Sensitivity themesN. 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
PURPLE- Themes that represent ties and special preservation defined by law.
- Very high criticality: maximum level of territorial sensitivity.
- Exclusion zone.
RED
- Themes that reveal a major inconsistency with the inclusion of the
plant; not expressed by specific law but from a technical opinion.
- High criticality: level of territorial sensitivity very high.
-Need more information and careful evaluation of all
critical factors involved.critical factors involved.
YELLOW
-Themes that have a certain incompatibility with the
inclusion of the plant.
- Average criticality: sensitive area.
-Critical evaluation of all factors involved: proper
plant choices or management could overcome criticalities.
WHITE- Themes reveal no special exclusion or inclusion of the plant building.
- No criticality: information themes that characterize territorial context.
GREEN- Themes that are preferential for the building of the plant.
- 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) areasprevail 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. Sensitivity maps
5. Web GIS
http://servizigis.arpa.emr.it/Geovistaweb/
• 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
Conclusions
– 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
