Dancing Stories: A Community Dance Residency in a Hospice in New Zealand

Canoes forging through cold waters, mountains rising from the sea, a heart beating under a mountain lake, an albatross sailing toward the Antarctic: these were the story-images of Coastal Mappings, a large-scale community project set in and around Dunedin, New Zealand. In the Coastal Mappings performance project, people in the last months of their lives joined cancer survivors, family members and other interested people in explorations of Pakeha myths (by European-settler descendents) and Maori myths (by descendents of the crews of the first canoes, first inhabitants of New Zealand). Together, we created personal landscapes through movement, storytelling, photography and video. In this essay, I discuss some of the opportunities, challenges and experiences of leading a community dance project in an intercultural social environment, and with people whose relationship to their environment is different from mine.

2009年3月对珠江广州大桥到海印桥段底栖动物群落结构进行调查。共采集6种底栖动物样品,其中霍夫水丝蚓为研究区域优势类群,密度和生物量相对丰度分别为96.3%和71.9%。海印桥底栖动物密度和生物量最大,分别为305280ind/m²和664.72g/m²;中大码头次之,分别为54144ind/m²和129.27g/m²;广州大桥最小,分别为43200ind/m²和93.87g/m²。底栖动物群落结构极为不均匀,广州大桥、中大码头和海印桥Shannon-Wiener多样性指数分别为0.34、0.27、0.14;Margalef多样性指数分别为0.32、0.19、0.11,均匀度指数0.19、0.20、0.13,物种丰度分别为6、4和3,属严重污染水平。对理化指标进行分析表明,溶解氧过低是生物多样性低的直接原因,控磷、除磷对降低水体营养水平,恢复生物多样性意义重大。     

Contrasting community and corporate perceptions of sustainability: A case study within the platinum mining region of South Africa

The concept of sustainable development is debatable within the mining context as the fact that mineral resources are non-renewable makes mining inherently unsustainable. The need for a realistic definition of sustainability that can be applied to mining is important, in light of claims by the industry that sustainable development principles underpin aspects of their operations. Furthermore, the socio-economic upliftment that should logically follow the implementation of these principles is not visible in many mining areas. Within the theoretical frameworks of intermediate sustainability, our study aimed to determine the level of sustainability that is appropriate for the mining context. The evaluation of community perspectives within the Rustenburg platinum region in South Africa as a case study, based on qualitative information derived from structured questionnaires and informal interviews brings further clarity. We found out that the environmental and social costs associated with mining were high, while economic benefits to surrounding communities were low. The perceptions of community and corporations were found to contrast sharply: the reality experienced by community members fell well short of the optimistic scenarios presented in the corporate social responsibility reports of the mining companies, which has implications for the mining industry in the area. The Rustenburg region is typical of mining areas, more especially the developing world, and application of a realistic sustainable development concept here can help the mining industry elsewhere to move its operations onto a genuinely more sustainable path.     

Computing Atmospheric Nutrient Loads to the Chesapeake Bay Watershed and Tidal Waters

Application of integrated Chesapeake Bay models of the airshed, watershed, and estuary support air and water nitrogen controls in the Chesapeake. The models include an airshed model of the Mid‐Atlantic region which tracks the estimated atmospheric deposition loads of nitrogen to the watershed, tidal Bay, and adjacent coastal ocean. The three integrated models allow tracking of the transport and fate of nitrogen air emissions, including deposition in the Chesapeake watershed, the subsequent uptake, transformation, and transport to Bay tidal waters, and their ultimate influence on Chesapeake water quality. This article describes the development of the airshed model, its application to scenarios supporting the Chesapeake Total Maximum Daily Load (TMDL), and key findings from the scenarios. Key findings are that the atmospheric deposition loads are among the largest input loads of nitrogen in the watershed, and that the indirect nitrogen deposition loads to the watershed, which are subsequently delivered to the Bay are larger than the direct loads of atmospheric nitrogen deposition to Chesapeake tidal waters. Atmospheric deposition loads of nitrogen deposited in coastal waters, which are exchanged with the Chesapeake, are also estimated. About half the atmospheric deposition loads of nitrogen originate from outside the Chesapeake watershed. For the first time in a TMDL, the loads of atmospheric nitrogen deposition are an explicit part of the TMDL load reductions.     

Prospects for the co‐management of mangrove ecosystems on the North Brazilian coast: Whose rights,whose duties and whose priorities?

This article describes the co‐management approach in situations of open access to and of increasing pressure on resources, using a mangrove coastal zone in North Brazil as an example. Co‐management clearly has the potential to turn nonviable, de facto open access to mangroves into effective common property management. Alliances of different political and ideological groups have been formed under the RESEX (reservas extrativistas — natural resource user reserve) model of coastal co‐management. Local economic interests have been mobilized as client constituencies. The RESEX system of co‐management assigns additional duties to both co‐managing parties, i.e., the state administration and the local users, in exchange for new rights. The authors argue that local support for the RESEX model has been gained on partially distorted premises. As the public authority passes on responsibility for management to local users under the RESEX model, this entails a number of duties for the local users. Thus local users assume the duty to implement and monitor resource management; they also appear to gain the right to take local decisions, such as excluding outsiders from resource access, and designing local resource management rules. However, as this article shows with two examples, some important new rights for local users under the RESEX co‐management concept are contrary to environmental legislation in force. This conflict is at present unresolved. It is argued that increased transparency about their precise rights for local resource co‐managers will considerably improve the prospects of coastal co‐management in Brazil.     

Is recycled water use risky? An Urban Australian community’s perspective

The emergence of a global water crisis has seen the necessity for a sustainable approach to water management. Policies directed towards water recycling have been implemented in many regions of the world. In Australia, prolonged drought conditions in most major cities during the past decade have led to serious national calls for less drinking water to be used (Prime Minister’s Science Engineering and Innovation Council, 2003), and a strategic policy response from many State Governments, including bold targets for water recycling. A key consideration to the realisation of these policies is greater understanding of community attitudes to recycled water use, without which, a number of recycled water projects have failed (Hurlimann and McKay, 2004). Despite the critical nature of community attitudes, little research has been conducted, especially in relation to perception of risk, which has been found to be critical in the adoption of new technologies (Cvetkovich and Lofstedt, 1999). This paper investigates an urban Australian community’s perception of risk involved with using recycled water. Key findings include: perception of risk increased as the use of recycled water became increasingly personal. Perception of risk was significantly negatively related to trust, perception of fairness and information. Trust in the Water Authority to manage risk was significantly related to perception of trust, communication and integrity of the Authority.     

Enhancing climate technology transfer through greater public–private cooperation: Lessons from Thailand and the Philippines

This article contributes to debates about climate change policy and technology transfer by analyzing the success factors underlying collaboration between private companies and communities in developing countries. To date, much attention to capacity building for enabling environments — including public–private collaboration — under the climate change convention has focused on state‐led initiatives and on the innovation and development of technologies. This article, instead, focuses on how private‐sector investors and host communities may collaborate in the diffusion of technologies, by reducing the costs of technology transfer, and making technology more appropriate to developing countries. The article describes cases of collaboration concerning waste management and waste‐to‐energy in Thailand and the Philippines. The article argues that successful public–private partnerships between investors and communities depends on minimizing transaction costs, strengthening collaborative (or assurance) mechanisms, and in maximizing public trust and accountability of partnerships. Lessons are then drawn for enhancing capacity building for technology transfer under the climate change convention and applications such as the Clean Development Mechanism.     

Success factors in community based natural resources management in northern Botswana: Lessons from practice

The article explores and examines challenges and lessons learned from the implementation of community based natural resources management (CBNRM) programmes in Ngamiland, northern Botswana. The article, based largely on primary data, with some secondary data sources, draws on the CBNRM framework, which promotes rural socio‐economic development and natural resources management. Among the key factors identified as pivotal to the success of CBNRM is broadening the consultation base during the mobilization phase of the programme to facilitate effective community participation and representation. Preparedness by both the implementing institutions and participating communities is also highlighted as key to effective mobilization. This means moving away from a conventional consultative forum, to a more multi‐faceted approach that will facilitate capturing the views of diverse user groups within the community. The article also suggests that feasibility studies are needed to address socio‐economic, political and cultural characteristics inherent in communities to guide programme implementation. To achieve increased community participation and enhance positive conservation attitudes, the article advocates a mobilization approach and practice that will effectively facilitate the process.     

Volunteer Environmental Monitoring and the Role of the Universities: The Case of Citizens' Environment Watch

Universities can provide a stable home for launching collaborative community research projects. Citizens' Environment Watch (CEW), an environmental monitoring initiative based at the University of Toronto, has made significant contributions to environmental education and stewardship in Ontario, Canada. Following dramatic cuts in provincial monitoring programs, citizens and youth have used chemical parameters and biological indicators to gauge water and air quality, and to identify areas requiring remediation and pollution prevention efforts. The relationship of Citizens' Environment Watch to government agencies, funders and other grassroots environmental groups has evolved over the past 5 years as CEW attempts to remain effective without taking on the investigative and enforcement roles to support the regulatory enforcement that has been largely abandoned by government. We explore the challenges inherent in developing and maintaining a volunteer organization that carries out rigorous and useful scientific work and we outline the ability of a university to help overcome these critical challenges. Finally, we present lessons learned for the benefit of other citizen and youth monitoring projects.
