The Millennium Ecosystem Assessment (MEA) is a major project initiated by U.N. Secretary General Kofi Annan in 2001 and completed in March, 2005. The project leveraged the contributions of 1360 experts from 95 countries, an 80-person independent board of review editors, and review comments from 850 experts and governments. The results are being published in more than a dozen reports listed on the MEA web site.
The results have also been summarized in a long PowerPoint presentation which can be downloaded from this page. Although over 6 megabytes, the larger of the three is well worth the effort. This presentation summarizes the project, findings, implications, and high level recommendations and should be required reading for anyone interested in the topic.
The project included a Scenarios Working Group whose contribution is summarized beginning on slide 55 of the long presentation. [Clicking on the thumbnail will produce a larger image]

Here are brief summaries of the four MEA scenarios:
