iEMSs Threads

iEMSs serves as an umbrella organization to support a number of “threads“, or “themes” that are organized into on-going community projects that evolve based on the open source principles. This means that we are encouraging and appreciating the participation in these projects, and we are trying to provide the infrastructure by developing web support and tools needed for these community projects.


If you have ideas for other “Threads” related to the iEMSs mission and objectives, please contact secretary (at) iemss (dot) org


So far, the following threads are started:


The topic of this thread is environmental modeling that uses resources or services that exist distributed in the Internet. The overall goal is to study methods and technologies of distributed environmental modeling.
We are especially interested in how to use existing standards or new standards that should be developed. This thread is a response to the iEMSs and OGC memorandum of understanding. The methods of work include development of demonstrator systems, preparation of scientific papers, organization and running of workshops and sessions in conferences, and collaborative work. The thread is open for participation of interested researchers.

The Community for Integrated Environmental Modeling (CIEM) or the IM4E (Integrated Modeling for the Environment) has been started as an effort to facilitate discussions and development of software tools and standards for integrated modeling.

Currently it is functioning as a Google Group, where you can join if interested. 


Here we collect links to educatonal resources that can help prepare courses, presentations, etc. We also intend to use this repository to present the materials that will be published in the new Journal rubric on “Teaching and Learning Tools/Software”.



Overall goals:
– Initiate and maintain a discussion process about feedbacks in socio-environmental systems
– Initiate, plan & publish papers

Current objectives:
1) Develop a common language and an analytical framework to study feedback mechanisms and their implementation in models / modelling frameworks.
2) Review and analyse existing approaches, identify state of the art and research needs.
3) Present (best practice) examples for technical implementation in broadly used simulation methods (ABM, CA, GA, ODE), identify and discuss advantages, shortcomings and research needs.

Publish results of 1 – 3 in various steps (currently 2 papers planned)

The ecosystem services concept enables development of policies that integrate social, economic, and ecological perspectives. Integrated environmental models are prone to support this concept as those can integrate several ecological functions, support the analysis of trade-offs and have been developed to a state where stakeholders can be involved and management solution can be derived.

How can environmental modelling support the implementation of the ecosystem services concept for environmental management? Towards appropriate methods for investigation, assessment, and implementation of ecosystem services in environmental management.

Topics of the thread

  • Model based quantifying ecosystem services
  • Use of ecosystem service modelling in regional case studies for environmental management
  • Who is using it where? Examples for the implementation of the ecosystem services concept in environmental management (under stakeholder involvement)

Thus in this thread we seek for discussions on regional studies and model development, that support a biophysical founded assessment of ecosystem services studies. Thus we seek for interdisciplinary examples by focussing on abiotic (water provisioning, regulating, soil protection) as well biotic processes (provisioning services, crop production, pollination, biocontrol). We welcome projects that performance those studies with modelling approaches on different levels of complexity. Second, we seek for investigations that specifically analyze trade-offs and off site effects. Thirdly, we appreciate to see how these results fed into a stakeholder process (for instance using multi criteria analysis and weighting of ecosystem services for assessment). We expect to get excellent examples of these issues to stimulate consistency and creativity of future ESS studies.
