While environmental change and policy responses to environmental threa
t have attracted considerable attention from government and industry o
ver the past decade, conventional approaches have tended to be individ
ualistic, naturalistic and government-led in orientation. This article
considers a perspective on 'sustainable development' which emphasizes
citizen-led initiatives. In particular, the possibilities for 'bridgi
ng the gap' between innovation processes and the implementation of tec
hnology are discussed. Three European case-studies are presented of a
constructive and citizen-led 'social management' of environmental chan
ge-urban ecology, wind energy and science shops. Conclusions are then
reached about the policy and theoretical significance of these social
experiments.
