Integrating top-down/bottom-up sustainability strategies: An ethical challenge

Abstract

Sustainable use of the planet will require multiple sustainability strategies, which will range from the entire system, the entire Earth, to the local or regional. Strategies starting at the highest system level are referred to as 'top-down,' and strategies designed for components, local or regional, are referred to as 'bottom-up.' Doubtless, several intermediate levels will eventually be required, although the number is far from clear at this time. It is abundantly clear that both top-down and bottom-up strategies must be integrated effectively or neither will work well. Furthermore, there will be significant uncertainties at both levels of organization, which will be reduced as evidence accumulates. However, sustainability is too complex and dynamic to reduce scientific uncertainty to a level desired by most decision makers. A greater emphasis on sustain-ethics and value judgments will improve communications between those working at different organizational levels since humankind's wish to leave a habitable planet for its descendants and those of other life forms is clearly a value judgment. © Inter-Research 2003.
