The economic part of an IEM may include, for example, such variables as production, consumption and employment, while the ecological part may include variables which reflect the association and diversity of ecosystems. However, despite the differences between these phenomena originating from various disciplines, they may interact with each other in an IEM. The examples of IEMs presented in Chapter 2, and followed in Chapter 3 by an overall discussion of the common characteristics, also showed the relevance of a systematic approach to the development of an IEM. date: 1987 date_type: published publisher: Springer id_number: 10.1007/978-94-009-3613-3_4 creators_browse_id: 1765 full_text_status: none series: Studies in Operational Regional Science volume: 2 number: 2 place_of_pub: Netherlands pagerange: 65-88 refereed: TRUE isbn: 978-94-009-3613-3 issn: 0924-4689 book_title: Integrated Environmental Modelling: Design and Tools coversheets_dirty: FALSE fp7_type: info:eu-repo/semantics/bookPart citation: Brouwer, F.
