The Society

The Integrated Assessment Society (TIAS) is a not-for-profit-entity created to promote the community of inter-disciplinary and disciplinary scientists, analysts and practitioners who develop and use integrated assessment. The goals of the society are to nurture this community, to promote the development of IA and to encourage its wise application.

TIAS Newsletter

What was Integrated Assessment again? The practice of Integrated Assessment is alive and growing. Perhaps it is time to refresh our understanding of IA. This is the feature of the March/April 2018 issue of the newsletter prepared by Jan Bakkes. Discussions among TIAS members and other practitioners in our network suggest that the most natural course of action is to revisit, and refresh, the Bellagio principles. This is important because the principles (or guidelines, or industry norms) should be useful for a wide variety of practices in a wide variety of contexts. Read more:


Send us your IA announcements: events, publications, etc. to profile on our website and/or in our quarterly newsletter. For more information on joining the global community of practitioners and scientists that use Integrated Assessment visit our membership page.


About Integrated Assessment and TIAS

TIAS defines Integrated assessment (IA) as the scientific “meta-discipline” that integrates knowledge about a problem domain and makes it available for societal learning and decision making processes. The integrating aspect of IA refers to scientific and stakeholder knowledge drawn from many disciplines as well as the use of wide range of methods.

IA plays an important role in environmental management by providing integrated knowledge management tools and processes for addressing complex environmental problems, and for promoting transformations towards sustainable development.

Members of TIAS are disciplinary and interdisciplinary scientists and practitioners from multiple sectors and from 23 countries around the world.
