Environmental stewardship—a concept that describes the relationships between humans and the environment—is gaining increased attention as an approach that can address planetary sustainability issues. In-depth empirical investigations of local environmental stewardship are needed to understand how social-ecological context influences stewardship, as well as the arrangement of conceptual elements in applied settings. This study addresses these needs by conducting an in-depth exploration of environmental stewardship in the Niagara Region of Canada. A single embedded case study design is employed, with environmental stewardship initiatives constituting the individual units of analysis with the case. Analysis of the spatial arrangement of a total of 89 initiatives indicated that initiatives tended to cluster closer to the Niagara River and in more populous municipalities. The significance of collaboration, tensions between the environment and economic development, and concerns about political impacts emerged as themes across contextual factors. The configuration of stewardship elements reveals interesting discrepancies between initiatives and previous stewardship research focused on larger scales, individuals, and organizations. Further analysis is encouraged to illuminate environmental stewardship in other settings as well as advance relational understanding of conceptual elements.  相似文献

Science Cities: What the Concept of the Creative City Means for Knowledge Production. – The article aims to show that the relationship of science and the city has changed since the 1970s in the context of the knowledgeable society. While cities have principally been regarded as the typical space of science, of new ideas and innovation for centuries, since the 1960s and 1970s universities, research institutes as well as industrial research institutes have relocated to the periphery of cities. There, however, these sites of knowledge have been organized in an ‘urban mode’. That means that the concept of the city as a place of science and innovation has determined the architectural, spatial, and social organization of these sites on the periphery of cities. Certain features of the city have been copied, such as social infrastructures, places of communication, restaurants, cafes etc., while others have been left out – housing, cinema, theatre etc. An ‘urban mode of knowledge production’ in the sense of a very stylized model of the city has become a tool to enhance the production of scientific and technological knowledge. – The article exemplifies this by focusing on a case study, namely of the so‐called ‘Science City’ of the Siemens Company in Munich‐Neuperlach.  相似文献

Incentive programs to encourage landowners to protect habitat should be carefully designed to avoid motivation crowding: basically, replacing intrinsic reasons such as a land ethic with extrinsic ones like payments. Little research on motivation crowding tests real programs, and no such work has been done in Canada. We surveyed farmers in Nova Scotia in 2017 to explore whether participation in a new incentive program called Wood Turtle Strides, or knowledge about a similar incentive program potentially available in the future, would alter reported motivations to use riparian setbacks and buffers. Motivations to use setbacks or buffers were heavily intrinsic across all four survey cohorts: wildlife stewardship and sacrifice motivated actions more than social pressures. We were not able to statistically test for motivational crowding due to low program uptake and thus post-program survey responses, but there was no evidence of second-hand crowding: farmers being motivated by hearing about a program in an adjacent jurisdiction. Findings point to the significance of wildlife stewardship for many farmers, and persistent resistance to conservation among others, as well as a risk of low additionality. More post-program research is necessary to fully understand the program's net impact on motivations and conservation.  相似文献

Zoos and aquariums are responding to the worldwide biodiversity crisis through major conservation initiatives like captive breeding for assurance populations and reintroduction programs. These institutions also fundraise, offer education programs, and provide critical research on biodiversity. Through a case study inside three accredited Canadian zoos, this paper illustrates that zoos and their staff members are being incorporated into many official species‐at‐risk recovery efforts on provincial, federal, and international levels. Specifically, the zoos studied are involved in every stage of the recovery process, from providing valuable research and habitat analyses, to captive breeding animals for reintroduction, to writing recovery strategies and creating recovery policy for multiple jurisdictional levels. Zoo staff indicate that zoos are uniquely suited to conservation because zoos have space, expertise, apolitical status, and the ability to connect with the public. Overall, the paper suggests that zoos can significantly contribute to species‐at‐risk protection and recovery in Canada and beyond.  相似文献

Sense of place was investigated in an interpretive approach to examine how it develops; how it varies cross-culturally among modern and indigenous peoples; and how it develops among various contexts (home and environs, family, community, and culture). Individual and group interviews were conducted using questionnaires on Banks Peninsula, New Zealand (a rural, farm-based setting) with 270 residents from 1987 to 1989, with 80 out-migrants interviewed around New Zealand in 1989. The methodology was based on phenomenology, ethnography, and social surveys. Statistical analyses indicated the significance of residential status and social belonging toward the development of a sense of place. Contextual influences were found to be important from qualitative data, with traditional culture of primary importance to Maori. Both Maori and European-descent respondents with long-term residence expressed a rooted sense of place for Peninsula environs. These respondents were less residentially mobile and were often tied to the land through ancestry and/or family farms. Newcomers to the region were usually treated as outsiders (for decades). The Maori community was partially sustained by a social network that extended beyond the Peninsula. Maori sense of place was based more on their cosmology and culture, which rooted them to their tribal territory spiritually and emotionally. To counter an amoral, modernist hegemony and to move toward community sustainability, postmodernists need to consider the significance of developing a place-based ideology that links people to place through a rooted sense of place. À l'aide d'une méthode interprétative, le sentiment d'appartenance à un milieu a été étudié pour examiner la manière dont il se développe, ses variations interculturelles parmi les populations modernes et autochtones, de même que l'incidence de divers éléments, tels la résidence et son voisinage, la famille, la collectivité et la culture, sur son développement. Entre 1987 et 1989, des entretiens individuels et de groupes ont été menés, en utilisant des questionnaires, auprès de 270 résidants demeurant dans la péninsule de Banks, en Nouvelle-Zélande, et appartenant à un milieu rural essentiellement agricole. De plus, en 1989, 80 émigrants répartis sur le territoire de la Nouvelle-Zélande ont été également intervieés. Les études phénoménologiques, ethnographiques et sociales ont servi de méthode fondamentale. L'analyse statistique a révélé l'importance de la qualité de résidant et l'importance de l'appartenance sociale sur le développement du sentiment d'appartenance à un milieu. D'après les données qualitatives, l'influence environnementale est significative, et la culture traditionnelle est capitale chez les Maoris. Les répondants établis depuis longtemps, qu'ils soient de descendance européenne ou maorie, ont manifesté un sentiment profond d'appartenance à leur milieu, que représente la péninsule. Ces répondants étaient relativement stables du point de vue résidentiel et possédaient souvent une terre ancestrale ou une ferme familiale. Les nouveaux arrivants ont été habituellement traités comme des étrangers (pendant des décennies). La communauté maorie a été soutenue en partie par un réseau social qui s'est étendu au-delà de la péninsule. Chez ce peuple, le sentiment d'appartenance au milieu s'appuie davantage sur la cosmologie et la culture, ce qui crée des liens spirituels et affectifs entre ces gens et leur territoire tribal. Pour s'opposer à l'hégémonie amorale et moderniste, et pour s'orienter vers la viabilité des collectivités, les post-modernistes doivent se rendre compte de l'importance d'élaborer une idéologie axée sur le milieu qui lie les gens par un sentiment profond d'appartenance.  相似文献

The paper reports a case study of factors attracting and retaining talented and creative workers in Halifax, Nova Scotia. All categories of workers interviewed mentioned quality of place and amenities in discussing their location preferences, but that could not fully explain their choices. For some occupations (like health research), talented people followed jobs; in other sectors (like music), talented workers migrated to a sympathetic locale with the right conditions for creative engagement; creative workers in some occupations (like those in architectural, engineering or planning consulting) were more rooted in place. The social dynamics—that is, positive and collaborative social networks within key sectors and a wider community perceived as welcoming and interesting—make this mid‐sized city attractive to talented workers. Local universities and a vibrant music scene generate a mutually reinforcing context that attracted mobile talented and creative workers to the city. Respondents noted Halifax's limited cultural diversity but did not report a perceived lack of tolerance as affecting their choices. In smaller cities, the social dynamics of place and workplace and the quality of life available may play more significant roles than tolerance in attracting and retaining talented workers, challenging a basic assumption of creative cities discourse.  相似文献
