Although recent studies have suggested that environmental participation may be a countertrend to decreasing civic engagement in the United States, there are very few empirical studies that examine these claims. This paper studies participation in local environmental stewardship as such a countertrend. Using data collected from participants in the Watershed Stewards Academies (WSAs) of Maryland, we assess how these organisations are successful in mobilising individuals to be environmentally and civically engaged in their communities. We argue that hybrid organisations like the WSAs represent a countertrend to diminishing rates of civic engagement by offering citizens what a “paper-membership” cannot: the chance to lead their own environmental restoration projects, create tangible change in their communities, and network with other like-minded individuals. These environmental programmes serve to diversify democracy at the local level, providing a unique form of civic engagement and enriching the connections between individual citizens and their civic communities. 相似文献

The availability of lithium resources for a transition to electric vehicles is a vital topic for transport technology strategy. Recent debate seems to have concluded that there is ‘sufficient’ lithium available, but for the purposes of a technological transition, time matters. It is not simply the quantity of resource that is relevant—the flow rate into society may be a much more difficult constraint and transient events have disrupted heavily concentrated material supply chains in the past. Furthermore, critical assumptions such as the presence of recycling systems may not be justified without policy support. Complacency is therefore not an appropriate stance for a robust evaluation of material risks in the case of lithium. 相似文献

This article reports a study of the public perception of large wood in rivers and streams in the United States. Large wood
is an element of freshwater aquatic ecosystems that has attracted much scientific interest in recent years because of its
value in biological and geomorphological processes. At the heart of the issue is the nature of the relationship between scientific
recognition of the ecological and geomorphological benefits of wood in rivers, management practices utilizing wood for river
remediation progress, and public perceptions of in-channel wood. Surveys of students’ perceptions of riverscapes with and
without large wood in the states of Colorado, Connecticut, Georgia, Illinois, Iowa, Missouri, Oregon, and Texas suggest that
many individuals in the United States adhere to traditionally negative views of wood. Except for students in Oregon, most
respondents considered photographs of riverscapes with wood to be less aesthetically pleasing and needing more improvement
than rivers without wood. Analysis of reasons given for improvement needs suggest that Oregon students are concerned with
improving channels without wood for fauna habitat, whereas respondents elsewhere focused on the need for cleaning wood-rich
channels for flood risk management. These results underscore the importance of public education to increase awareness of the
geomorphological and ecological significance of wood in stream systems. This awareness should foster more positive attitudes
toward wood. An integrated program of research, education, and policy is advocated to bridge the gap between scientific knowledge
and public perception for effective management and restoration of river systems with wood. 相似文献
