Scientists and stakeholders from all over Europe have worked together for three years (1998-2001) to develop visions of possible futures of Europe and its regions up to the year 2050. To this end, new methodologies of participatory scenario analysis were explored and employed. Integrated Assessment models and tools have been used as supportive equipment for analysis and as a means for communication. The project was unique in its flexible approach, i.e., allowing the various regional teams as well as the European scenario team to develop and use participatory and modelling approaches most suitable to the qualities and culture of their particular region.
