海河流域水环境危机和适度恢复对策的探讨

20世纪50年代以来,海河流域水资源短缺和水环境恶化问题越来越突出。河道断流,湿地萎缩,地下水大量超采,水污染和水土流失加剧,流域水环境已经恶化到十分危险的境地。回顾、总结流域水资源开发利用的历史可以清楚地看出,经济社会发展大大超过了水资源的承载能力,是海河流域水生态环境恶化的根本原因。本文认为,改善和恢复水环境,必须以供定需,以水定发展,根据流域水资源条件确定产业结构、经济规模和发展方向,努力实现人与自然的和谐相处,以水资源的可持续利用保障经济社会的可持续发展。

Taking stock of community-based flood risk management in Malawi: different stakeholders,different perspectives

Current flood risk strategies in Malawi are characterized by community-based flood risk management (CB-FRM), even though studies explicitly documenting evidence of successful CB-FRM remain limited. This paper investigates the realities and challenges of CB-FRM as seen through a lens of different stakeholders. In order to capture the experiences of CB-FRM, a predominantly qualitative research framework was developed. In 2016, 11 focus group discussions with stakeholder groups (local communities, local government and non-governmental organisations) were held. Additionally, informal discussions, field visits, a short survey and an extensive desk study were undertaken. The findings were analysed according to the major themes that emerged related to the realities and challenges of specific stakeholder groups. Although response and relief still remain prominent components of CB-FRM in Malawi, a number of mitigation and preparedness activities is observed. However, a lack of in-country resources, relief-oriented aid approaches and an ‘aid dependency’ syndrome represent obstacles. Different stakeholder groups share similar challenges in terms of financing, participation, decentralised governance and project management. Lack of project sustainability and localised ownership also emerged as major challenges. The identified challenges shed light on the frontiers and directions in which improvements are needed, thus offering a valuable contribution to the existing knowledgebase.

长江流域地质—生态环境的演化机制及综合自然灾害区划

地质－生态环境是新一轮国土资源大调查的新概念, 同时也是现代地学研究的一个重要的范畴,在分析地质－生态环境系统及其演变的动力学机制的基础上,本文首先探索了长江流域地质－生态环境的演化机制,结合其自然环境状况,揭示了长江流域自然灾害形成的综合机制及其分布规律;并在此基础上,依托图文信息可视化系统技术手段,采取自上而下和自下而上两种进行综合自然灾害区划,其区划等级体系为3个自然灾害区和9个自然灾害亚区,为合理利用自然资源及防治自然灾害和环境退化提供了基本依据。

Politicisation of Humanitarian Aid and Its Consequences for Afghans

This paper outlines the implications of international approaches to humanitarian assistance in Afghanistan, focusing in particular on the period since the Taliban assumed power. It argues that international efforts to use conditionality on humanitarian assistance have proved ineffective in influencing the Taliban's policies, and have been implemented despite the negative impact on the welfare of the whole population. Efforts to adopt a principled approach to aid programming in this environment have also raised many ethical dilemmas which are likely to remain major challenges in that country and elsewhere.     

Challenges to mobilising resources for disaster recovery and reconstruction: perspectives of the Haitian diaspora

Diasporas and diaspora non‐governmental organisations (NGOs) are increasingly important as resource lifelines to their home countries, yet the resources that they mobilise, the types of challenges that they face, and their coping mechanisms are not well explored or understood in the context of disaster recovery. To fill this knowledge gap, this study employed an inductive qualitative methodological approach, using interviews to comprehend the role played by Haitian diaspora NGOs after the catastrophic earthquake in 2010. It found that resources take four common forms: event fundraisers; financial and material donations from supporters; remittances; and volunteer labour. Challenges include an overreliance on diaspora donors, competition among NGOs, and what is perceived as inequitable funding practices towards diaspora NGOs. The findings provide insights centred on better coordination among diaspora NGOs, as well as between diaspora NGOs and other local and international NGOs and local governments and international institutions, to ensure more efficient delivery of services to survivors.     

干旱、农业旱灾与农户旱灾脆弱性分析——以邢台县典型农户为例

从微观农户角度分析了干旱、农业旱灾和农户旱灾脆弱性的成因。文章认为,自然降水不足或与作物需求匹配不均是造成农业干旱的动力,农户对干旱的应付能力不足是导致干旱成灾的原因。这种应付能力既受区域水资源可利用量的限制,也与农户的作物种植结构、灌溉支付能力、风险认识和对农业的依赖程度有关。农户旱灾脆弱性既与农业干旱有关,又受到人均资源和收入、种植和消费结构、生态环境质量、政策、市场价格等多重因素的作用。最脆     

Mass casualty incident after the Taba terrorist attack: an organisational and medical challenge

Two suicide bombings in and around Taba, Egypt, on 7 October 2004 created a complex medical and organisational situation. Since most victims were Israeli tourists, the National Emergency and Disaster Management Division handled their evacuation and treatment. This paper describes the event chronologically, as well as the organisational and management challenges confronted and applied solutions. Forty-nine emergency personnel and physicians were flown early to the disaster area to reinforce scarce local medical resources. Two hundred casualties were recorded: 32 dead and 168 injured. Eilat hospital was transformed into a triage facility. Thirty-two seriously injured patients were flown to two remote trauma centres in central Israel. Management of mass casualty incidents is difficult when local resources are inadequate. An effective response should include: rapid transportation of experienced trauma teams to the disaster zone; conversion of local medical amenities into a triage centre; and rapid evacuation of the seriously injured to higher level medical facilities.     

西部地区重大工程建设中的泥石流灾害 --兼论其与环境的互馈作用

在西部大开发过程中,许多重大工程建设涉及泥石流灾害的问题.讨论了工程活动、泥石流及山地环境之间的相互作用和影响.工程活动往往受到泥石流、山地环境的制约,同时它作为活的因素,又积极地影响着泥石流和山地环境,促使其产生次生演化,泥石流和山地环境的次生演化常会对工程活动产生次生制约.泥石流的发生会危及工程和人类的安全,破坏地表,破坏生态环境;人类工程活动若不遵守自然规律,过度向山地索取,必将导致山地环境退化和泥石流的广泛活动及频繁发生,甚至引起泥石流活动范围扩大和成灾规律改变.     

Disaster risk reduction and ‘built‐in’ resilience: towards overarching principles for construction practice

The emerging emphasis on disaster risk reduction has broadened the range of experts whose knowledge must be garnered to resolve complex socio‐technical challenges. This paper examines the role and position of the construction sector for addressing these concerns. Specifically, it examines the recursive nature of practices within the built environment, which can be seen as deeply ingraining fragmented approaches to the development process. These, in turn, render the industry a difficult arena within which to enact structural and cultural change. Based on a wide body of literature on resiliency a set of overarching principles are proffered to help inform efforts to overcome some of the barriers to creating a more resilient built environment. It is argued that these principles offer a point of departure for embedding resilience considerations at both project and institutional levels, although real change would demand challenging some of the conventions that currently underpin construction development.     

Fieldwork after conflict: contextualising the challenges of access and data quality

Despite sustained scholarly interest in post‐conflict states, there has not been a thorough review and analysis of associated methodology and the challenges of conducting research in these contexts. Addressing this gap, this paper directs attention to the particular effects of these settings on access and data quality and their ramifications for the resulting scholarship. It assesses the intrinsic challenges of performing fieldwork in these environments, drawing on both relevant social science literature and the authors’ experiences of carrying out research in Afghanistan and Timor‐Leste. The study demonstrates that the post‐conflict environment moulds research design and, consequently, influences how questions are answered as well as the questions asked. Moreover, it highlights ways to mitigate these issues. This work is of relevance to scholars planning to engage in field research and to researchers reflecting upon their work, as well as to policymakers who are considering undertaking programmes or commissioning research in post‐conflict areas.
