Sustainable development has emerged as a distinctive marker of place identity in addition to traditional markers such as buildings and spectacles. Climate change mitigation as a potential place brand, indicating sustainable development, is in focus of this article, comparing such efforts in three Swedish towns. Based on documentary studies and interviews, it demonstrates how one town has been successful in branding itself as “the Greenest City in Europe”, whereas mitigation efforts in two other towns are barely known outside the town halls. In the first case, a combination of material, symbolic, and institutional components has been decisive in establishing a brand with internal and external legitimacy. This case highlights the importance of a dedicated network of influential actors and a potent governance structure visualising the will of a town to make its climate mitigation efforts known. Despite similar material conditions, the two others come short on the symbolic and the institutional dimensions, although they may still have a potential for future success in terms of mitigation both in practice and as a marker of identity.  相似文献

Well-being is a positive physical, mental and social state and has increasingly become an area of interest to researchers and policy-makers internationally. This paper presents results from research that analyses the well-being benefits gained by different sections of society through viewing, engaging with, and accessing woodlands and forests in Britain. We draw on 31 studies undertaken since 2001 and present a meta-analysis of quantitative data and a meta-synthesis of qualitative data to explore the range of benefits and associated activities in woodlands, and their social distribution. We also present a state-of-the-art typology of well-being benefits for woodlands in Britain. The findings illustrate the wide range of well-being benefits gained by different social groups through various forms of engagement with and activities undertaken in woodlands. We illustrate the wide range of meanings and values attached to trees and woodlands across different social groups. The evidence also illustrates how carefully designed and targeted interventions can be particularly effective in enabling and encouraging people to visit woodland sites, to participate or get involved in new activities and, therefore, to realise a range of well-being benefits.  相似文献
