Stream: Model Development, Analysis and Application: Methodological Aspects

 

D8. Comparison of and guidelines for environmental modelling paradigms
Tony Jakeman, Olivier Barreteau, Mark Borsuk, Andrea Rizzoli, Alexey Voinov

This workshop follows on from its associated session. Please see that session (D4) description.
The Workshop will be structured by the organisers to address already identified key issues as well as ones that emerge from the associated session itself, with the aim of preparing an excellent EMS PP.
The organisers also welcome prior application of modelling paradigms to a set of common case studies they are setting up for the purposes of comparative analysis.

D9. The Community for Integrated Environmental Modelling (CIEM): Current status and future direction
Gerry Laniak, Gene Whelan

At the 2010 iEMSs conference a workshop entitled "Web Portal for the Community for Integrated Environmental Modelling" was presented. The goals of the workshop were to introduce the CIEM web-portal (iemHUB.org) to the wider modelling community, obtain feedback and comments, and encourage its use as a key resource for sharing knowledge and technologies related to IEM. Since the Ottawa conference both the CIEM and the web-portal have progressed in important ways, including the convening of an international summit for integrated environmental modelling and advancements to the appearance and functionality of the web portal. As a community of communities the CIEM shares interests, goals, and activities with many other communities of practice (e.g., iEMSs, CSDMS, CUASHI, ISCMEM), each of which has a focus on a topic of particular relevance to IEM. Several important interactions with these communities have taken place.

The goals of this workshop are to:

  1. Review the latest developments of the CIEM, other closely related communities, and the iemHUB web portal
  2. Discuss and compile specific goals and activities to further increase the awareness and value of CIEM and
  3. Discuss how CIEM and other related communities can further coordinate and collaborate to strengthen the overall value and use of IEM.

Related to these goals the following key questions will be discussed:

  • How can the CIEM better facilitate the exchange of IEM science and technology across the international community?
  • What formal/informal relationships between CIEM and other communities should be pursued (e.g., discipline specific communities)?
  • How can the iemHUB web-portal better serve the needs of the community?
  • What social and technical issues related to IEM should CIEM address and what outcomes would be desired?

D10. Complex problems, simple answers, difficult solutions
Alexey Voinov, Ralf Seppelt

Scientist, society and politicians become aware, that although our understanding of environmental processes is increasing, yet our ability of taking the right decisions is still limited. For example, we already know much about the climate change and how it can impact our livelyhoods, we already see what are the possible conflicts due to limited resources such as food, energy and land, we already realize how loss of biodiversity and ecosystem functioning can be detrimental to our life-support systems - however, in all these cases we still cannot develop appropriate decisions to avoid or adapt to these changes. There are many examples when knowledge and understanding does not necessarily produce adequate reaction in form of policies or management strategies. We see that increasing complexity of models used for coping with the complexity of the systems we analyze, may not necessarily produce the kind of understanding that is appropriate for action. We may hypothesize that this is because we are treating complexity with complexity, while the real power of modelling is simplification and the ability to abstract to higher level of analysis, where the solutions may be easier to identify and communicate. According to Einstein "problems cannot be solved at the same level of awareness that created them". By moving from one level of complexity to another, it may be easier to find solutions. For example, we already know what has to be done to solve the problem of climate change. What we do not know is how to make this happen.

In this workshop we would like to focus on multi-hierarchical modelling, and look at systems that are studied in different levels of complexity to see how we can inform one hierarchical level with findings from another, and how we can move from one level of complexity to another.
What are the key success stories of model applications that have been influential for sustainable resource use of communities? What have been the major caveats? How the model complexity was justified? How model complexity can be changed? How to move from one complexity level to another? We are at the crossroads, good ideas welcome.

D12. First joint workshop on data mining and intelligent decision support systems for environmental scientists (IV W-DMTES-2012 and IEDSS-2012)
Karina Gibert, Joaquin Izquierdo, Miquel Sanchez-Marre, Ignasi Rodriguez-Roda, Rick Sojda, Geoff Holmes, Antonio Ciampi, Ioannis Athanasiadis, Joaquim Comas

Fourth workshop on data mining as a tool for environmental scientists (D-DMTES-2012) and second workshop on intelligent environmental decision support systems for environmental scientists (IEDSS-2012).
This workshop (W-DMTES-2012) aims to provide a global perspective of the complete and complex process of transforming raw data into really useful decisional knowledge in environmental domains. Data mining processes transforms the data into relevant information, and permits to induce decision knowledge from it, even taking into account the doctrinae corpus in the target domain, when available. Intelligent decision support systems can use this knowledge to provide rational support to the complex decision making process in front of high levels of uncertainty, multifactors influences and, eventually, different experts opinions. The combination of both disciplines provides highly powerful tools in better knowledge of environmental systems as well as better control and management. This joint workshop is in close connection with session A3 (S-DMTES-2012) and session D7 (S-IEDSS-2012), and pretends to promote the interaction among the Environmental Sciences, the Data Mining and the Intelligent Decision Support Systems communities and related fields, to discuss the joint contribution of data mining techniques and intelligent decision support systems to knowledge discovery in environmental sciences, as well as to make both data mining techniques and Intelligent Decision Support Systems more accessible to environmental modellers and to give data miners and knowledge engineers a better idea of the needs and desires of the environmental community. Authors are invited to submit ABSTRACTS to this workshop, in which a short number of 5 minutes presentations will be chosen in order to deliver maximum time to global discussion. Participants in S-DMTES-2012 and/or session S-IEDSS-2012 are specially invited to take active participation in this workshop.

Dear Participants,
please take a look at the working paper which provides a first insight of some software tools for both Data Mining and Intelligent Environmental Decision Support System as a basis for discussion. The paper is not exhaustive and one of the goals of the workshop will be to exchange experiences on the use of these tools among participants, as well as to elicit the strong link between DM and IEDSS. Enlarging discussion to other DM or IEDSS software tools is welcomed.

If you are interested to include some other tools in the discussion, please contact Dr. Karina Gibert (karina.gibert (at) upc.edu).
