This article explores the local impact of the catastrophic earthquake in northern Pakistan on 8 October 2005. Drawing on field research, including interviews with 40 earthquake survivors, the post-disaster analysis presented here focuses upon risk awareness and the reactions of respondents to the 7.6 magnitude earthquake that devastated areas of Azad Jammu and Kashmir State, and North-West Frontier Province. The analysis provides insights into local perceptions of seismic hazard and exposure as well as survivors' priorities with regard to rebuilding and reconstruction. The article suggests that the tragedy of the devastating earthquake is entangled in a deeper knot of causal factors that are social, economic and political in nature. Rapid population growth, urbanisation, changing building styles, environmental degradation and lack of preparedness and mitigation are associated with the circumstances that place the population at risk. Remarks concerning present and future risk reduction efforts are included.  相似文献

乾隆三年宁夏大地震救济刍议   总被引:1,自引:0,他引:1  
清乾隆三年宁夏府大地震,造成了严重的社会危机.震后地方政府首先作出反应,一边开展自救,一边向中央政府汇报.中央政府在接到灾情汇报后,组织了一系列赈济.文章从政府层面面对地震灾害后出现的诸问题角度,探讨清代中央政府与地方政府应对地震灾害的措施.指出正是中央政府与地方政府紧密的配合,才避免了地震灾情的恶化.  相似文献

随着人类逐步迈入风险社会,生态环境事故产生的诱因更多地集中于科学技术,且对相关事故进行责任认定难度巨大.政府在处理相关问题时可能面对经济发展和环境保护相冲突以及决策的知识性匮乏等问题,这就要求在新社会背景下从积极和消极两方面对政府的环境责任进行有效的重构.  相似文献

为了解会泽铅锌尾矿区自然发生的豆科植物对重金属的耐性,研究了该地区自然发生的3种豆科植物在Pb2+/Zn2+单盐和双盐胁迫下种子萌发及其幼苗生长的情况。研究表明:在本实验所设的浓度范围内,Pb2+/Zn2+单独胁迫时,对供试植物种子及幼苗的生长主要表现为抑制作用,除苕子(Vicia Cracca L.)外,金属离子的质量浓度越大抑制作用越强;Pb2+/Zn2+共同胁迫时出现复杂的交互作用。对于苕子的种子及幼苗的生长,Pb2+/Zn2+呈现明显的相互加强抑制作用;对于其它2种植物,当Zn2+浓度在低质量浓度时,Pb2+似乎对Zn2+抑制有缓解作用,同样当Pb2+浓度在低质量浓度时,Zn2+似乎对Pb2+抑制有缓解作用,但是当Pb2+/Zn2+高浓度时,Pb2+/Zn2+呈现明显的相互加强抑制作用。不论是单盐还是双盐,苕子对的耐性最强,其次为白三叶(Trifolium repens L.),紫花苜蓿(Medicago sativa L.)最弱。会泽铅锌尾矿区重金属含量高是该区植被恢复的最大障碍,进一步研究植物对Pb2+及Zn2+的耐受性对于铅锌尾矿区的植被恢复有极其重要的意义。  相似文献

Abstract

Engaging with dialogue concerning the relevance and applicability of social capital to a model of sustainable community development, we illustrate an in-depth case of a community experiencing an ideological clash with the dominant politico-societal structures. We argue that while the exclusivity of bonding social capital has been described as the ‘dark side’, it may be essential for progressive sustainable community development (PSCD). When faced with a development threat, such bonds are essential for building links, bridges and solidarity, enabling cultural reproduction and promoting environmental protection for sustainability.  相似文献

The following article examines Haiti's past, present and future sustainability based on a thorough cause and effect analysis of the country's current situation, research on relevant social and economic factors, years of field experience, as well as training and consulting for businesses, political parties and non-profit organisations. In addition to identifying the current major core conflicts of Haiti, the article also suggests solutions to various social, economical and environmental issues.  相似文献

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

This paper explores community perspectives of environmental change and the role development actors in the regional Nepali town of Nepalganj. Understanding these perceptions is crucial for planning future adaptation to climate change and ensuring that these measures are sustainable and in line with community priorities. Firstly, I contend that whilst the local community in Nepalganj may be experiencing the impacts of climate change, they are unfamiliar and disassociated with the concept. Secondly, I identify a number of risks and opportunities around the role of local government, international development organisations and local non-government organisations in future adaptation actions. Participant perceptions of these institutions in their community reinforce a number of established critiques of development around themes such as poor consultation and short project timelines. The long-term success of adaptation actions will be shaped by the ability and willingness of development actors to evolve their practices by listening to local communities.  相似文献

为加强施工场景下的工程车辆安全监管,针对施工场景下工程车辆易互相遮挡、局部特征与全局特征相似以及场景环境复杂的问题,提出一种基于自适应局部斥力与归一化面积损失的工程车辆目标检测算法。其中自适应局部斥力损失可使待检测工程车辆与其他工程车辆目标框相排斥;归一化面积损失使网络学习集中在面积具有相对较大预测误差的工程车辆上;并结合聚类算法设定更适合工程车辆的锚框。研究结果表明:算法可实现在困难场景下对压路机、挖掘机、装载机3类工程车辆的快速准确检测与识别,具有较高的工程应用价值。  相似文献
