Global Scenarios in Historic Perspective in Scenario Assessment Report
Paul Raskin, F. Monks, Teresa Ribeiro, Detlef van Vuuren, Monika Zurek
This chapter reviews the historical context of scenarios, beginning with brief sketches of early scenario activity, from its post-World War II origins up to about a decade ago. It focuses in particular on the subset of environmental global scenario projects that have a public policy and scientific orientation, since these are of greatest interest to the Millennium Ecosystem Assessment. Special consideration is given to the following post-1995 global scenario building exercises: Global Scenarios Group, Global Environment Outlook, Special Report on Emissions Scenarios, World Business Council for Sustainable Development, World Water Vision, and the Organisation for Economic Co-operation and Development. These scenarios, despite their diversity, are rooted in a common set of archetypal visions of the future: evolution, progression, and decline.
