Millennium Ecosystem Assessment Scenarios
Focus: plausible future changes in ecosystems, in the supply of and demand for ecosystem services, and in the consequent changes in human well-beingKey concerns: identified through a survey of user needs and interviews with decision-makers and leaders. Included:• globalization• leadership• poverty and inequality• technology• local flexibility• surprises

The Global Orchestration scenario depicts a worldwide connected society in which global markets are well developed. Supra-national institutions are well placed to deal with global environmental problems, such as climate change and fisheries. However, their reactive approach to ecosystem management makes them vulnerable to surprises arising from delayed action or unexpected regional changes.

The Order from Strength scenario represents a regionalized and fragmented world concerned with security and protection, emphasizing primarily regional markets, and paying little attention to the common goods, and with an individualistic attitude toward ecosystem management.
Order from Strength
Nelson et al., 2005

The Adapting Mosaic scenario depicts a fragmented world resulting from discredited global institutions. It sees the rise of local ecosystem management strategies and the strengthening of local institutions. Investments in human and social capital are geared toward improving knowledge about ecosystem functioning and management, resulting in a better understanding of the importance of resilience, fragility, and local flexibility of ecosystems.

The TechnoGarden scenario depicts a globally connected world relying strongly on technology and on highly managed and often-engineered ecosystems to deliver needed goods and services. Overall, eco-efficiency improves, but it is shadowed by the risks inherent in large-scale humanmade solutions.

Global Scenarios Group (GSG): Three archetypal scenarios of the future
Conventional Worlds: current trends play out without major discontinuity and surprise in the evolution of institutions, environmental systems and human values.
Barbarization: fundamental social change occurs, but is unwelcome, bringing great human misery and collapse of civilized norms.
Great Transitions: fundamental social transformation but to a new and arguably higher stage of human civilization.
Gallopin et al., 1997

The dominant characteristic of this scenario is the assumption that actors at all levels – local, national, regional and international, and from all sectors, including government, private and civil – actually follow through on the pledges made to date to address environmental and social concerns. This implies behaviour that honours not only the letter, but also the spirit of these promises.
