1. Web Based Integrated Models for Participatory Planning National Technical University of Athens School of Rural and Surveying Engineering Department of Geography and Regional Planning Elias Grammatikogiannis Maria Giaoutzi June 20th - June 23th, 2011 , University of Cantabria, Santander, Spain "Cities, Technologies and Planning" (CTP 11) Sixth International Workshop on "Geographical Analysis, Urban Modeling, Spatial Statistics" GEOG-AN-MOD 11

2. The development of an Integrated Assessment Model (IAM) that embeds the web dimension to promote Participatory Spatial Planning by increasing awareness in society, on environmental issues GOAL

3. PARTS OF THE PAPER PART 1: Concepts of IA and P articipatory IA PART 2: List of I ntegrated A ssessment M odels PART 3: the LandGEM IA Model PART 4: Development of a PIA Model

4. 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)

5. 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 ) PART 1: Concepts of IA and PIA

6. 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

8. 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

12. How it Works!! PART 3: LandGEM IA Model Climate Type Landfill Open and Closure Year Mass of Waste CAA Default Parameters Inventory Default Parameters Landfill Characteristics Default Parameters Options Greenhouse Gas Emissions LandGEM Equation I II II III

13. I. Inputs Climate : conventional and arid type of climate Landfill Open and Closure Year : Year of opening and closure of the landfill Waste Acceptance Data : The volume of waste accepted in Landfill in (Mg) How it works!! PART 3: LandGEM IA Model

14. II. Model Equation k = methane generation rate determines the rate of methane generation for the mass of waste L 0 = potential methane generation capacity the higher the cellulose contents of the waste, the higher the value of Lo How it Works!! PART 3: LandGEM IA Model

17. A Web based Integrated Assessment Model- LandGEM PART 4: Development of PIA Model Structure of a Web Based IA Model

19. 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

20. Structure of Participatory Integrated Assessment Model PART 4: Development of PIA Model

21. 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 experts and laymen

22. 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

23. 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

24. 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.
