Exploring system interactions for building resilience within coastal environments and communities

This paper focuses on identifying examples of first-order system interactions, which make important contributions to building coastal resilience for coastal zone management. This discussion is based on an application of the Institutional Analysis and Development Framework to a case-study analysis of coastal management in South Australia. The study suggests that cross-scale interactions and informal relationships within and between users and managers are key interactions defining resilience outcomes within the current system. A significant constraint on improving resilience was the lack of evaluative criteria for identifying sustainable forms of system behaviour. The paper argues that resilience is a function of a normative statement on the characteristics desirable in the functioning system. Analyses of coastal resilience, which facilitate greater understanding of the range of complexities in coastal behaviour, are therefore central to gaining the most useful insights into the options and pathways for building more sustainable coastal futures.     

地铁施工风险应急管理研究

针对近年来地铁施工事故频发,难以快速、有针对性地进行应急处置的问题,通过对近年来地铁施工事故案例的统计,分析导致地铁施工事故的相关因素,用Protege软件对以往地铁施工事故应急案例建立知识本体模型。通过目标案例与本体库中的源案例进行相似度计算与匹配,检索出案例库中相似度超过阈值的源案例,然后再对比筛选后的源案例与目标案例之间的关键属性相似度,从而决定进行规则推理或直接参考该案例的应急措施,以此提高应急处置的速度与针对性。

Evaluating Rapid Participatory Rural Appraisal as an Assessment of Ethnoecological Knowledge and Local Biodiversity Patterns

Abstract:  There is a pressing need to find both locally and globally relevant tools to measure and compare biodiversity patterns. Traditional ecological knowledge (TEK) is important to biodiversity monitoring, but has a contested role in preliminary biodiversity assessments. We examined rapid participatory rural appraisal (rPRA) (a tool commonly used for local needs assessments) as an alternative to surveys of vascular plants conducted by people with local knowledge. We used rPRA to determine the local-knowledge consensus on the average richness, diversity, and height of local grasses and trees in three habitats surrounding Boumba, Niger, bordering Park-W. We then conducted our own vascular plant surveys to collect information on plant richness, abundance, and structure. Using a qualitative ranking, we compared TEK-based assessments of diversity patterns with our survey-based assessments. The TEK-based assessments matched survey-based assessments on measures of height and density for grasses and trees and tree richness. The two assessments correlated poorly on herb richness and Simpson's D value for both trees and grasses. Plant life form and gender of the participant affected the way diversity patterns were described, which highlights the usefulness of TEK in explaining local realities and indicates limitations of using TEK as a large-scale assessment tool. Our results demonstrate that rPRA can serve to combine local-knowledge inquiry with scientific study at a cost lower than vascular plant surveys and demonstrates a useful blunt tool for preliminary biodiversity assessment.     

Exploring the lay/expert divide: the attribution of responsibilities for coal ash pollution in Tuzla,Bosnia and Herzegovina

Invoking expert knowledge is a common strategy in attempts to settle environmental disputes. However, the validity of expertise is contingent upon the context in which an actor is recognised as an expert. In complex environmental conflicts the distinction between lay and expert knowledge is not always fixed a priori. However, as conflicts unfold, intervening parties tend to present their cases in ways that reinforce this distinction. This is apparent in the attribution of environmental responsibilities. This paper presents an empirical case of an environmental conflict related to land contamination due to coal ash disposal in Bosnia and Herzegovina. The analysis revealed two polar positions in the conflict: the first one, mainly held by scientists and industry representatives, invoked expert knowledge and presented a distributed approach to the attribution of responsibilities; the second one, mainly held by local residents and municipal officials, presented an experiential understanding of pollution, as lay knowledge, and attributed direct responsibilities to the local energy industry. The paper concludes that the persistence of the distinction between expert and lay knowledge is a manifestation of the social structures that underlie the conflict.     

Made in conflict. Local residents' construction of a local environmental problem

The aim of this paper is to understand how local residents participate in the construction of local environmental problems and to evaluate a particular analytical approach in environmental sociology to study this phenomenon. The paper is based on an interview study with a sample of local residents. The analysis demonstrates how the local residents attempt to construct a local environmental problem. In particular, the study focuses on how involved actors are positioned, how different sorts of knowledge claims are used, and how the neglect the residents perceive from the authorities affects the attempt to construct a local environmental problem. The study shows that the local residents play a central role in the construction of the situation and that the evaluated model could be very helpful as an analytical tool in the investigation of local residents' participation in the construction of environmental problems.     

Local knowledge and climate change adaptation on Erub Island,Torres Strait

Local knowledge is a valuable asset in observing and managing environmental change, and importantly, is an unheralded source of adaptive capacity. Torres Strait Islanders are no exception, having used such knowledge to adapt to biophysical changes in their environment for centuries. This article explores the ways in which Islanders have coped in the past with environmental changes to plan for their future. This article focuses on Erub Island in the eastern group of islands in the Torres Strait and charts the adaptation actions or activities employed by respected locals (Elders and Aunties). Drawing on their local knowledge, these actions or activities have included the building of rock walls and wind breaks, using native species to re-vegetate sand cays and the coastal foreshore, applying self-sufficient practices such as fish traps and gardening, reading and respecting country, and transferring this knowledge to the younger generation. In this way, it is the Islanders themselves who detail, based on their local knowledge, what is most appropriate for their community.

农田面源污染团队式治理方法初探

我国农田面源污染的环境经济治理方式还不健全,急需适应我国农业特征的面源污染治理手段。现阶段环境税费政策通过对农业投入的控制,容易影响农户农业生产的积极性,而且还存在一定的技术难度和设备成本约束。团队式治理方法是一种更直接的面源污染监管手段,通过将农户组成团队,比管理单个农户节约成本;通过一定的奖惩措施激励农户主动调整污染排放水平;给定的合约条件约束了农户在重复博弈下的"搭便车"行为,保证了团队的存续。
