Luka Kuol 《Disasters》2019,43(Z1):S28-S35
Past disasters have been well studied, but the challenge of using the findings to improve the management of future events remains a daunting task. This paper argues that there are new and complex disasters of which the state itself has become the main source, as reflected in the Horn of Africa. This region is characterised by increasing vulnerability owing to the alarming decline of democracy and the rise of authoritarianism. These new disasters are less researched because of the hazard of conducting fieldwork in such environments. However, there is mounting evidence to highlight the possibility of performing research in these settings, but not by employing traditional methods; rather, these tools may need to be customised for use. One key policy implication here is that donors may need to invest more money in analysing these new disasters and they may need to consider building and strengthening genuine partnerships between Northern and Southern research institutions  相似文献

The promulgation of the South African Disaster Management Act No. 57 of 2002 and the National Disaster Management Policy Framework of 2005 placed South Africa at the international forefront by integrating disaster risk reduction into all spheres of government through a decentralised approach. Yet, good policy and legislation do not necessarily translate into good practice. This paper provides a critical analysis of the Act and Policy Framework. Using qualitative research methods, it analyses the attitudes and perceptions of senior public officials on all levels of government, the private sector and academia. The study finds that one of the weakest aspects of the Act and Framework is the absence of clear guidance to local municipalities. The placement of the disaster risk management function on all tiers of government remains problematic, funding is inadequate and overall knowledge and capacities for disaster risk reduction are insufficient.  相似文献

Most members of Taiwan's indigenous communities live in areas that are prone to natural disasters. Yet, due to their marginalised cultural, economic and political status, each time such calamities strike, any assistance they receive is usually provided without considering their actual needs. The areas hardest hit by Typhoon Morakot in August 2009 were the indigenous villages in the southern and eastern parts of the island. After the initial emergency relief efforts had been completed, there remained the highly challenging task of reconstruction and the resettlement of those who lost their homes and livelihoods. This paper examines the cultural conflicts that arose during the reconstruction process, with special emphasis on the participation of Taiwan's indigenous communities and their capacity for resilience. It was found that community participation and identification are key issues in effective disaster governance.  相似文献

By the start of 2014, violent conflict had erupted across much of South Sudan following initial violence in Juba on 15 December 2013. The speed with which the fighting has spread raises questions regarding the impact of national‐level politics on violence at the local level. This article develops a framework in which violent conflict can be comprehended as a response to the interruption of the negotiation of the balance of power between groups; the negotiation is interrupted when that balance tips in favour of one group, such as through changes in the national political market or government reforms. The article provides two cases studies of attempts to strengthen the state that inadvertently interrupted local power relations between groups. In response, the groups engaged in violent conflict to reinstate a balance of power. Both examples involve conflict among Dinka groups from 2005 to 2008.  相似文献

In this paper a large-scale community-based disaster risk-assessment project, undertaken in the Dr Kenneth Kaunda District Municipality in the North-West Province of South Africa, is evaluated. In contrast to other disaster risk management consultancy projects in South Africa, this project included a significant skills transfer component to the at-risk communities and local government officials. In this evaluation, the authors draw on their own experiences in implementing this and similar projects, a review of the project management documents is undertaken, and a focus group interview with facilitators involved in the project is used as a primary source. The discussion is further contextualised in terms of community-based disaster risk assessment theory and the existing literature on disaster risk assessment in South Africa. Logistical and data quality issues as well as staff turnover were found to be concerns during the project. From the findings, it is argued that the common practice of outsourcing disaster risk-management projects is not conducive to effective disaster risk management. Local government entities should take responsibility for disaster risk assessment as a continual activity. This is in contrast to the view currently manifesting in South Africa as a set of bureaucratic actions undertaken by consultants to achieve ‘legislative compliance’ for municipalities.  相似文献

自然灾害脆弱性研究进展   总被引:7,自引:0,他引:7  
近年来,在国际上日益重视防灾减灾的背景下,脆弱性研究已成为灾害学研究的主题并逐渐融入社会可持续发展策略。在回顾国内外灾害脆弱性研究发展的基础上,阐述了脆弱性的基本内涵,探究了自然灾害脆弱性的基本构成,并对灾害研究领域中容易混淆的危险性、脆弱型、风险、易损性与恢复力等概念进行了辨析。研究归纳总结了开展脆弱性评估的5种经典模式,风险-灾害(RH)模式、压力释放(PAR)模式、政治经济模式、基于区域的综合脆弱性模式和恢复力模式。并且指出,自然灾害研究领域的脆弱性评估应主要基于历史数据、指标体系和实际调查的灾损率曲线。从发展趋势来看,脆弱性研究正日益着重多领域合作、多对象细化和除指标体系外多种方法的综合应用,旨在从人类社会本身找出灾难根源,为灾害保险和政府决策提供有效指导。  相似文献

The response to the earthquakes in Nepal on 25 April and 12 May 2015 was as overwhelming as the magnitude of the events themselves. Tensions between the humanitarian imperative and the post-conflict state-building agenda soon became evident. Many actors offered support by creatively complying with the state's approach, whereas others bypassed official channels completely. In post-conflict settings such as Nepal, the situation is especially complicated because of the contradiction between policies underscoring the importance of the state in the response and the reality of the fragility of the state, which often leads to the significant involvement of aid organisations. The post-conflict political landscape of Nepal shaped the contours of the response, as well as how actors decided to operate within them. This paper, based on empirical findings from four months of research, contributes to a better understanding of the intricacies of the post-conflict and post-disaster nexus in the context of a state-led response.  相似文献

Many agencies working on disaster risk reduction use vulnerability and capacity assessment (VCA) to identify vulnerable groups, to assess their needs and capacities, and to develop appropriate programmes and policies. In theory, VCA offers a good opportunity to incorporate disabled people's needs and resources in counter‐disaster programming. This paper seeks to establish and explain the extent to which disability is included in VCA in practice. It reviews VCA reports and findings, formal VCA guidance, and other methodological literature. The review indicates that disability is a neglected issue in VCA practice and that manuals and guidelines, while promoting the general ideal of inclusiveness, are insufficiently aware of the challenges to achieving this in practice and do not offer enough guidance on how to reach and include disabled people. Ways of overcoming these problems are suggested. However, the real challenge may be to change core attitudes and perceptions of disability within implementing organisations.  相似文献

Disaster resettlement, as a mitigation and preparedness measure, entails significant economic, physical, and social impacts, which continue to challenge understanding of recovery from major events, especially regarding the extent of the context and environmental efforts to rebuild livelihoods. Based on a case study of Qinling Mountains, China, this research investigates the effects of disaster resettlement from a livelihoods perspective. Methodologically, it proposes a framework that combines the pressure–state–response framework and the sustainable livelihoods approach, and it employs a structural equation model to examine how specific factors affect disaster resettlement. The results indicate that conflicts may occur during and after resettlement owing to the difference or disparity between the concerns of resettled peasants and those of the government. Consequently, the risks related to livelihoods need to be taken seriously. Effective risk communication is critical to bridge the gap between different stakeholders. The paper concludes with some practical and policy recommendations.  相似文献

As a result of the increase in natural disaster losses, policy‐makers, practitioners, and members of the research community around the world are seeking effective and efficient means of overcoming or minimising them. Although various theoretical constructs are beneficial to understanding the disaster phenomenon and the means of minimising losses, the disaster risk management process becomes less effective if theory and practice are set apart from one another. Consequently, this paper seeks to establish a relationship between two theoretical constructs, ‘disaster risk reduction (DRR)’ and ‘vulnerability reduction’, and to develop a holistic approach to DRR with particular reference to improving its applicability in practical settings. It is based on a literature review and on an overall understanding gained through two case studies of post‐disaster infrastructure reconstruction projects in Sri Lanka and three expert interviews in Sri Lanka and the United Kingdom.  相似文献

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  相似文献

Four hypotheses concerning the relationship between climate-related disasters and conflict are tested using archaeological data in a controlled cross-cultural comparison. The four hypotheses are (1) Conflict increases following climate-related disasters because local economic conditions deprive polities of tax revenue so that they can no longer suppress conflict; (2) Conflict increases following climate-related disasters because existing social inequalities lead to conflicts over differential access to resources; (3) Conflict increases following climate-related disasters because migration forces population into condensed settlements ripe for conflict; and (4) Conflict increases following climate-related disasters in polities where leaders tightly control access to political authority because leaders may use violence to maintain control over the resources they use to secure support from other elites. Only the fourth hypothesis is supported. It is argued that understanding pre-disaster political strategies is key to understanding post-disaster conflict.  相似文献
