Factual databanks can make an important contribution to environmental management. They help considerably with the difficult processes of integrating the various scientific languages used, and also with the development of valid methods for interdisciplinary research. In the planning the Aeolian project (a multidisciplinary study of an Archipelago north of Sicily), it was considered useful to include a group of workers on methodology and computer science. The hope is that they will help to facilitate the exchange of data and thus contribute to a better understanding of the various phenomena occurring on the islands. This paper discusses the conceptual working aspects of environmental information, together with those characteristics that render it suitable for inclusion in a modern computer‐based system.
