The first workshop of the European Forum on Integrated Environmental Assessment (EFIEA) took place in Amsterdam on 12-14 March 1998. Integrated Environmental Assessment is loosely defined as policy-relevant, multi-disciplinary research into complex environmental issues. The workshop provided an opportunity for EFIEA members to get acquainted with one another and one another’s work, and to discuss the goals and challenges in the field of Integrated Environmental Assessment for the next five years. The meeting was hosted by the Institute for Environmental Studies (IVM) of the Vrije Universiteit in Amsterdam. Over 45 members of the EFIEA participated in the workshop and all contributed to the discussions and planning activities. Participants included researchers from the natural and social sciences as well as policy makers, DG’s and EEA representatives. These various contributions provided the basis of the workshop report. The keynote speeches of the workshop will be published in a special issue of the journal Environmental Modelling and Assessment (EMA).
