Integrated Assessment – IA:
Interdisciplinary process of combining, interpreting and communicating knowledge
from diverse scientific disciplines
(where the whole cause–effect chain of a problem
can be evaluated from a synoptic perspective)
PART 1: Concepts of IA and PIA
(Rotmans and Dowlatabadi,1997)
![Page 5: Web Based Integrated Models for Participatory Planning](https://reader036.vdocuments.us/reader036/viewer/2022062319/55745269d8b42a0c468b4b4c/html5/thumbnails/5.jpg)
reflective and iterative participatory process
that takes into account the social context in which
scientific and political activities operate
Participatory Integrated Assessment - PIA
(ULYSSES Project)
approach that allows to combine evaluations of experts (scientific
judgments) and lay people (valuations of non-scientists)
(Schlumpf et al. (1999 )

IAMs: simulate natural and socio-economic
systems
Goal: to analyze one or more of the cause-
effect chains of an environmental problem,
to describe the relation between human activity and environmental change

PART 2: List of Integrated Assessment Models
Divided into:
I. evaluation policy models
II. optimization policy models
![Page 8: Web Based Integrated Models for Participatory Planning](https://reader036.vdocuments.us/reader036/viewer/2022062319/55745269d8b42a0c468b4b4c/html5/thumbnails/8.jpg)
I. Evaluation Policy Models
consider the effects of a single policy option on
biosphere, climate, and
economic systems and are also known as simulation models
PART 2: List of Integrated Assessment Models

II. Optimization Policy Models
assess the optimal policy (trade off expected costs and benefits of climate change control)
identify policies (minimize the costs of achieving a particular goal)
simulate the effects of an efficient level of
carbon abatement on the world economy

Transformation of Web Based LandGEM into a PIA Model
PART 4: Development of PIA Model
STEPS:Step 1. Transformation of the
aggregated input data, into personal data (individuals’ behavioural patterns)
Step 2. Estimation of personal contribution to GHGs
Step 3. Calculation of the impacts of the behaviour “what if everyone acts like the model user”?
Step 4. Sharing, with other users, the results of personal contributions

Attributes of PIA Model PART 4: Development of PIA Model
PIA Model Facilitates Participatory Process as able to:
Estimate greenhouse gas emissions from household waste disposal
Assess greenhouse gas emissions “if everyone acts like the model user”
Share users’ greenhouse gas emissions on web
Provide an open in access, autonomous and web accessible model for both expertsexperts and laymenlaymen
![Page 22: Web Based Integrated Models for Participatory Planning](https://reader036.vdocuments.us/reader036/viewer/2022062319/55745269d8b42a0c468b4b4c/html5/thumbnails/22.jpg)
CONCLUSIONS I
1. the transformation process, may hold for any IA model, that simulates socio-economic, environmental etc. phenomena
2. useful tool for handling problems that require both the monitoring of behavioural patterns and the assessment of peoples’ contribution to the problem under study
![Page 23: Web Based Integrated Models for Participatory Planning](https://reader036.vdocuments.us/reader036/viewer/2022062319/55745269d8b42a0c468b4b4c/html5/thumbnails/23.jpg)
CONCLUSIONS II
3. the transformation from the LandGEM expert oriented model into a user oriented model enables the communication of the scientific knowledge to the broader public
4. by embedding, the web dimension an
open access, innovative and autonomous PIA model has been created, that could inform people on the impacts of their behaviour
![Page 24: Web Based Integrated Models for Participatory Planning](https://reader036.vdocuments.us/reader036/viewer/2022062319/55745269d8b42a0c468b4b4c/html5/thumbnails/24.jpg)
CONCLUSIONS III
5. LandGEM PIA model could be combined with important tools of the planning process, such as web questionnaires, geovisualization tools, multicriteria methods etc.
6. barriers to be overcome in order to implement the Web Based PIA Models efficiently, are the user friendliness of the model interface that should become as accessible as possible to the lay user.
