Locating Existing Best Management Practices Within a Watershed: The Value of Multiple Methods

There is an increasing need to document the impacts of conservation‐related best management practices (BMPs) on water quality within a watershed. However, this impact analysis depends upon accurate geospatial locations of existing practices, which are difficult to obtain. This study demonstrates and evaluates three different methods for obtaining geospatial information for BMPs. This study was focused on the Eagle Creek Watershed, a mixed use watershed in central Indiana. We obtained geospatial information for BMPs through government records, producer interviews, and remote‐sensing aerial photo interpretation. Aerial photos were also used to validate the government records and producer interviews. This study shows the variation in results obtained from the three sources of information as well as the benefits and drawbacks of each method. Using only one method for obtaining BMP information can be incomplete, and this study demonstrates how multiple methods can be used for the most accurate picture.     

Use of Small-area Data to Support a Community Agenda in Boston Chinatown

Boston Chinatown is a community that grapples with a constant pressure from the downtown area to build new and larger buildings. The effort to preserve the residential aspect of Chinatown has used data analysis in recent years by forming partnerships with academics. This has allowed for more sophisticated studies of traffic injuries, scientific surveys of residents about environmental health, the measurement of noise levels and the construction of physical and electronic mapping of data. While not the only factor contributing to the community's efforts to question the role of development, these data have added useful tools that reduce, but do not eliminate, the disparity between what the community brings to discussions about the environmental impact of development and what the developers have at their disposal.     

Inspiring England's urban fringes: multi-functionality and planning

The urban fringe has been described as 'planning's last frontier'; a zone of transition and interface between town and country where a broad variety of land uses and activities come together, and where development pressure is often intense. In this paper, we argue that the urban fringe possesses special characteristics, making it more than simply a transitional landscape. These characteristics centre on patterns of land use, biodiversity and leisure/development opportunity which are unique to the urban edge and to land extending away from built-up areas. The uniqueness, diversity and particular dynamics of the urban fringe demands a special brand of planning and management response. Therefore we suggest that the principle of 'multi-functionality' provides a framework for action, showing how diversity can be managed and supported. Through brief case studies, we demonstrate how functional interactions at the urban fringe might be promoted in the future.     

Recognising interdependence and defining multi-level governance in city sustainability plans

Abstract

This paper examines the nature of the relationship between sustainable waste management behaviour between the ‘home’ and ‘work’ settings. A questionnaire survey of 566 employees of the Cornwall NHS (National Health Service) was used to examine the nature of the behaviour between the two settings and to understand the main factors influencing the behaviour. The results indicate that there is strong link in the behaviour of individuals between the two settings, with employees who practised recycling activities at home also being more likely to practise a similar behaviour at work. There was also some similarity in the level of sustainability of the behaviour between the two settings. These behaviours were strongly influenced by the underlying attitudes and beliefs of the staff towards the environment. The implications for policy-making to improve sustainable waste management behaviour amongst individuals in England and Wales are also discussed.     

Dealing with uncertainty: a case study of controlling insect populations in natural ecosystems

This paper analyses the political process for handling an outbreak of an insect causing human allergic reactions. In the southern part of the Swedish island Gotland in the Baltic Sea, an outbreak of the northern pine processionary moth, Thaumetopoea pinivora, has occurred. With regard to the human nuisance and long-term effects on the tourist industry, demands have been raised for intervention to reduce and control the insect population. At the same time, there have been warnings against treating the insect population because there are knowledge gaps concerning the wider ecological consequences, including effects on biodiversity. This paper analyses the political process and its problem-solving efforts. Of particular interest is how it dealt with the issue of uncertainty. It was found that the uncertainty associated with the issue hindered the development of a shared understanding of the problem and a possible solution. There seems to be a growing need in society to develop the institutional capacity to handle complex issues that cross different sectors, regulatory frameworks and policy targets.     

Territorial politics and the success of collaborative environmental governance: local and regional partnerships compared

The paper explores the role local governments and territorial proximity play in the efficiency of collaborative environmental governance. It develops the hypothesis that the representatives of local authorities involved in partnerships possess resources to diminish the pitfalls of sustainable governance, facilitate coordination, and contribute to the success of shared policy-making. Four French and English partnerships are presented. They include a diversity of stakeholders such as fisheries, ports, farmers, yachting associations, environmental NGOs, or local authorities. Thereby, the paper develops whether and under which conditions local governments play a positive or negative role, as well as comparing territorial levels of implementation and the effects of geographical proximity. It is shown that collaboration at the regional level prevents the integration of decision-making in organisational networks, the inclusion of citizens, and the development of social responsibility for stakeholders – the partnership acting as a formalisation of pre-existing lobbying. Locally, governments assume inter-organisational leadership and do contribute to the institutionalisation of the new forums. Yet, local successes of partnerships answer logics of social, rather than environmental, regulation. The local attenuation of usage conflicts does not necessarily reduce the negative effects of those usages on the environment. By stressing a collaborative definition of environmental problems, the partnerships tend to sideline substantial policy changes, and possibly conflict with the goals and long-term temporality of sustainable governance.     

Local governments in the driving seat? A comparative analysis of public and private responsibilities for adaptation to climate change in European and North-American cities

The division of responsibilities between public and private actors has become a key governance issue for adaptation to climate change in urban areas. This paper offers a systematic, comparative analysis of three empirical studies which analysed how and why responsibilities were divided between public and private actors for the governance of local urban climate adaptation. For 20 governance arrangements in European and North-American cities, the divisions of responsibilities and the underlying rationales of actors for those divisions were analysed and compared. Data were gathered through content analysis of over 100 policy documents, 97 in-depth interviews and 2 multi-stakeholder workshops. The comparative analysis reveals that local public authorities are the key actors, as they bear the majority of responsibilities for climate proofing their cities. In this stage of policy emergence, local authorities are clearly in the driving seat. It is envisaged that local public authorities need to more actively engage the different private actors such as citizens, civil society and businesses through governance networks along with the maturation of the policy field and the expected acceleration of climate impacts in the coming decades.     

Conflict and collective action in Tonle Sap fisheries: adapting governance to support community livelihoods

This paper presents the results of action research conducted from 2009 to 2015 on the dynamics of resource conflict concerning fisheries and livelihoods in the Tonle Sap Lake, as well as the institutional context and strategies for institutional adaptation to address such conflicts equitably. Over the past 15 years, Cambodia has made significant advances in building the policy framework, regulations and institutions to support community‐based fisheries management and increase the sector's contribution to the rural economy. However, fundamental challenges of increased resource conflict and loss of livelihoods by the most vulnerable remain. Key sources of conflict include destructive and illegal fishing practices, clearing of flooded forests, competing uses of land and water, and overlapping resource claims. Addressing these challenges requires collective action by all key actors: local fishers, the private sector, civil society, development partners, and government from the local to the national level. We identify and elaborate upon four governance priorities: (1) clarify roles and responsibilities in fisheries management; (2) link civil society and government efforts in law enforcement; (3) strengthen partnerships for livelihoods development; and (4) integrate fisheries management into decentralised development planning.     

陆海统筹视角下我国海洋生态城的空间模式及潜在风险

近年来我国1/3以上的沿海城市正在积极建设海洋生态城,呈现“组团-分带”型、“核心-放射”型、“陆岛-网链”型等空间模式,努力实现陆海生态环境约束下生态、生产、生活的整合,但当前初步的规划建设却潜藏着生态恶化、体制摩擦、功能冲突等风险.因此,今后的发展应突破“重陆轻海”的范式局限,从陆海统筹的战略高度努力实现海洋生态城的过程化、区域化和协同化管理,对沿海城市陆海统筹发展等具有借鉴意义.     

川西北高寒草地沙化土壤特征及治理模式探讨——以阿坝州红原县为例

通过对川西北高寒草地不同类型的沙化样地0—10cm,10～20cm和20～30cm土壤有机质、pH和含水量进行分析。结果表明：（1）随着沙化程度加重,土壤有机质含量和土壤含水量明显降低;（2）随着土层深度增加,土壤有机质含量降低;未沙化、轻度沙化样地的土壤含水量随土层深度增加而降低,重度沙化样地则相反;（3）中度和重度沙化样地土壤pH约7．0,未沙化和轻度沙化pH值在6．5左右;沙地土壤有机质与pH值呈显著负相关关系,沙化土壤有机碳与水分损失是一个正反馈。鉴于川西高寒草地特殊环境,探讨了选用适宜的多年生高原药用植物或者其他高价值资源植物作为固沙材料,将治沙与经济发展相结合,建立高寒沙化草地治理模式。
