Mitigating climate change is recognized as an increasingly urgent task that requires understanding a range of different strategies, including voluntary behavior change. Among the psychological barriers to behavior change are perceptions of powerlessness and the commons dilemma. This paper examines the association between these factors in a sample of New Zealand citizens and clarifies their importance in relation to other barriers to action to mitigate climate change, including uncertainty and perceived risk. Stronger perceptions of powerlessness and the commons dilemma were related to lower levels of action to mitigate climate change and lesser importance being placed upon climate change as an influence on individual actions. The perceived risk of climate change and the perception that humans influence climate change were the strongest predictors of mitigation action.  相似文献

The recent moratorium on the commercial at-sea driftnet fishery for wild Irish Atlantic salmon (Salmo salar L.) attempts to halt the decline witnessed in these stocks over the past three decades. The research investigated stakeholder attitudes to the perceived effects on stock recovery, in Irish rivers and estuaries, of seal predation and seal culling. Structured interviews conducted with 10 key stakeholders during June 2007 revealed divisive attitudes and a feeling of powerlessness in relation to stock recovery, which are impeding successful management of salmon stocks. However, areas of common ground exist between stakeholders, which lay the foundation for a sustainable way forward.  相似文献
