Although most disasters are not entirely unexpected and therefore can, to varying degrees, be mitigated for, the UK construction sector does not play a sufficiently integrated role in disaster risk management. Research is reported on the development of a knowledge database and decision support framework to enable more effective disaster risk-management strategies from a construction perspective. A survey of UK professionals involved with disaster risk-management activities (i.e. emergency planning, constructing, urban planning, insurance) indicates that knowledge and awareness of integrated approaches is poor, and the construction sector as a key stakeholder and potential resource is not being used sufficiently. Key recommendations to improve the construction sector in the process are as follows: construction-related stakeholders need to become more involved in groups such as Local Resilience Teams and Forums; risk and hazard awareness training needs to be integrated systematically into the professional training of architects, planners, engineers, developers, etc.; and the construction sector should embrace and pre-empt regulatory changes regarding resilient construction requirements. Bien que la plupart des catastrophes ne soient pas complètement inattendues et que, dans des proportions variables, elles puissent par conséquent être atténuées, l'industrie britannique du bâtiment ne s'implique pas suffisamment dans la gestion des risques de catastrophes. Il est rendu compte de recherches sur le développement d'une base de connaissances et d'un cadre de soutien à la prise de décision afin de rendre des stratégies de gestion des risques de catastrophes plus efficaces du point de vue de l'industrie du bâtiment. Une enquête auprès des professionnels britanniques impliqués dans les activités de gestion des risques de catastrophes (à savoir, planification des mesures d'urgence, construction, aménagement urbain, assurances) indique que le niveau de connaissances et de sensibilisation en matière d'approches intégrées est faible, et que le secteur du bâtiment en tant que partie prenante essentielle et ressource potentielle n'est pas suffisamment utilisé. Les principales recommandations pour améliorer le secteur du bâtiment sont les suivantes: il faut que les parties prenantes liées à l'industrie du bâtiment soient plus impliquées dans des groupes tels que les Equipes et les Forums Locaux de Résistance (Local Resilience Teams and Forums); il est nécessaire que les formations de sensibilisation aux risques et aux dangers soient systématiquement intégrées dans la formation professionnelle des architectes, des urbanistes, des ingénieurs, des promoteurs, etc., et le secteur du bâtiment devrait adopter facilement et anticiper les changements de réglementation relatifs aux obligations de résistance des constructions.

ABSTRACTIn this paper we examine the current state of play with regards to the security of smart city initiatives. Smart city technologies are promoted as an effective way to counter and manage uncertainty and urban risks through the effective and efficient delivery of services, yet paradoxically they create new vulnerabilities and threats, including making city infrastructure and services insecure, brittle, and open to extended forms of criminal activity. This paradox has largely been ignored or underestimated by commercial and governmental interests or tackled through a technically-mediated mitigation approach. We identify five forms of vulnerabilities with respect to smart city technologies, detail the present extent of cyberattacks on networked infrastructure and services, and present a number of illustrative examples. We then adopt a normative approach to explore existing mitigation strategies, suggesting a wider set of systemic interventions (including security-by-design, remedial security patching and replacement, formation of core security and computer emergency response teams, a change in procurement procedures, and continuing professional development). We discuss how this approach might be enacted and enforced through market-led and regulation/management measures, and then examine a more radical preventative approach to security. 相似文献

The range and variety of the career of Sir Raymond Unwin should be evidence of its permanent significance, but the same diversity has often inhibited a full understanding of his contributions. It has not been well enough realized, for example, that in depending upon Howard, Hinton, Carpenter, Ruskin, and Morris for much of his inspiration, he belonged well within a larger context of British social and artistic thought. World War I also brought on u change in the circumstances of his career, identifying him as an individualistic artist-architect before, and a governmental leader und technician afterward. Nevertheless, consistent themes run through both phases, among them the absolute right of public amenity, the priority of the community as a social ideal over the city as a physical reality, the house as the basis for sound planning because of its importance to family life, and the desirability of separating the concerns of land layout from those of building design. Unlike many of his contemporaries, he believed that tradition was an indispensable stimulus to creativity. 相似文献

This review examines two new socio-ecological imperatives that have the potential to reshape planning practice and policy: urban climate governance and governance for resilience. The roots of the new imperatives lie in international city collaborative networks funded by philanthropy organisations that operate at city scale. City networks operating at the metropolitan scale raise issues for Australian cities with distributed governance. This practice review considers the early manifestation of both imperatives in what might be termed ‘policy experiments’ in Australia’s two largest cities: the new climate governance framework emerging through the City of Sydney’s collaboration with the C40 network and the resilience regime being shaped by the City of Melbourne’s partnership with Rockefeller Foundation’s Resilient 100 program. Whilst our early analysis has accentuated the positive to some degree, pointing to different, if preliminary, forms of success in both Sydney and Melbourne, the limits and frustrations that present in both contexts cannot be discounted. Urban planners in many world cities and regions will need to consider and possibly absorb these new agendas of urban climate governance and governing for resilience driven by international city collaborative networks. 相似文献

In this paper, a flash flood that occurred in the Brazilian state of Santa Catarina in 2008 is used to investigate the existence of spatial spillovers from natural disasters in geographically-linked areas. In order to do so, we estimated a Difference-in-Differences model that explicitly allows for the existence of spatial interactions within affected and unaffected regions. Our results show that municipalities directly affected by the flood suffered an 7.6% decrease in GDP per capita in the year of the disaster. Three years after the flood, however, GDP per capita rebounded back to pre-disaster levels in all sectors but the Agricultural sector. Finally, our spatial estimations show that spillovers exist and are economically relevant. 相似文献

Municipal amalgamations have historically accounted for a substantial reduction in the number of councils in Australia. Proponents of municipal consolidation typically argue that substantial economic benefits will inevitably flow from fewer, larger municipal councils. This article seeks to evaluate the validity of the generic case for council amalgamation in Australia. 相似文献

This article and the commentaries which accompany it centres on a reflection by consultant-academic Nathaniel Lichfield on his work on planned development and the evaluation of the impacts of such development, over a career spanning the past 60 years. His work, in the UK and across the world, had a formative influence on generations of planners brought up on his texts. In this presentation, David Adams sets the context of his contribution. The heart of the article is a reflective synthesis by Lichfield on his own work from his first major contribution in 1956, to its evolution in the 1960s into the technique of the Planning Balance Sheet, and later, Community Impact Evaluation. His starting point is that there can be urban and regional planning which does not lead to physical development on the ground and there can be such development on the ground that has not been influenced by government led urban and regional planning. Neither of these is planned development. This takes place when the two are fused together in practice: the development and the government led planning. It is this simple concept, with particular emphasis on its economics, which was treated at length in the Economics of Planned Development (1956). In order to fully describe the concept, the book's contents are summarized in the first half of this article following an introduction of the background. Following the publication of the book, Lichfield's professional and academic work took him in many directions, much of which fell loosely under the ambit of the economics of planned development. His contributions were not written up as sequels to the book but rather in related books, papers and articles under an array of topics. He terms these 'the children of EPD'. They are described in the second half of the article, grouped in relation, as appropriate, to each of the main themes of the 1956 book and extensions of it. Lichfield's article is followed by three commentaries. The first, by Mike Teitz, positions his work and its later development in the changing context of the times. The second, by Barrie Needham, provides some critical thoughts on how well the concept of 'planned development' travels transnationally into different institutional contexts. The third, from consultant-planner Alan Wenban-Smith, himself working on policy evaluation in the UK, explores the practical and methodological robustness of Lichfield's concepts. Overall, the piece provides an input to reflections on the relation between state and market in the development process and on the evaluative stance the state should take to its interventions. 相似文献

In Nigeria, environmental problems are severe, particularly in the Niger Delta region of the country. In that region, crude petroleum activities damage the fertility of the soil, and destroy wildlife and the breeding ground for marine fishes because of the toxicity of oil and gas. Consequently, the indigenous people are impoverished, with attendant increase in environmental abuse occasioned by their struggle for survival. The various government programmes aimed at ameliorating their plight have failed due to inefficiency and corruption. The federal government is also thwarting efforts by Niger Deltans at resource control that would help to distribute equitably the oil resources of the region. This opposition to a derivation‐based redress to the development problems of Niger Delta is partly responsible for the anarchy that the region is experiencing. Unless the underlying problems are addressed, the Niger Delta will remain a source of instability for the Nigerian federation. Therefore, the oil of the Niger Delta needs exploitation in ways that advance the cause of development in Nigeria without compromising the environmental values of that region and the welfare of its people. 相似文献

This paper investigates the relationship between the social capital and economic resilience of Italian provinces during the Great Recession. It focuses on social economy organizations' internal and external relational dimensions to proxy forms of bonding and bridging social capital. Through an econometric analysis, I find that indicators depicting the diffusion of volunteering and cooperative employment are positively related to a measure of resilience, confirming the hypothesis that social capital can shape local reactions to crises. I also find a negative relationship between the local resilience and social cooperatives' density, highlighting how the latter indicator does not seize virtuous forms of social capital. 相似文献

Problem, research strategy, and findings: Conventional hazard mitigation and pre-disaster recovery planning processes typically begin with hazard scenarios that illustrate probable events and analyze their impacts on the built environment. The processes conclude with responses to the hypothetical disruption that focus on “hardening” buildings or structures or removing them from threatened areas. These approaches understate the importance of natural and social sources of adaptive capacity. Three “proof-of-principle” exercises designed to strengthen the Federal Emergency Management Agency (FEMA)'s Risk MAP (Risk Mapping, Assessment, and Planning) process in Washington State suggest how better to conduct hazard mitigation and recovery planning. Each begins with workshops where stakeholders identify built, natural, and social assets that contribute to human wellbeing (HWB) before introducing earthquake scenarios that affect HWB. Participants then identify assets that could facilitate adaptation to changed circumstances (a “new normal”). Participants discuss how these assets would achieve the goals of comprehensive community planning as well as hazard mitigation and recovery from disaster. Neighborhood-scale social organization emerges as an important priority.Takeaway for practice: Asset-based approaches enable communities to better recover from disaster and adapt to a post-disaster “new normal.” By premising planning discussions on a more holistic set of assets, communities can balance physical recovery goals with qualities that help them to adapt to future change. Furthermore, thinking about recovering before an event actually occurs can enlarge the menu of mitigation strategies. Planning for adaptation can also help communities achieve many non-risk-related objectives. 相似文献

This paper analyses the long-term relationship between regional inequality and economic development. Our data set includes information on national and regional per capita GDP for four countries: France, Italy, Portugal and Spain, compiled on a decadal basis for the period 1860–2010. Using parametric and semiparametric regressions, our results confirm the rise and fall of regional inequalities over time although in recent decades they are on the rise again. Finally, we identify structural change as being a significant transmission mechanism of the inverted-U relationship. The arrival of technological shocks, beginning during the onset of industrialization, and the transition from agrarian to industrial economies, would explain this result. 相似文献

This paper analyses the effects of the sectoral structure on the economic resilience of Chilean regions during the shocks of the 1998 Asian and 2008 financial crises by employing cycle dissection, phase-differentiated spatially extended shift-share analysis, and regional analysis indices. Regions with more diversified structures exhibited better performance during the crises. Certain service sectors moderated the impacts of the crises in the resistance phases, and in turn, were drivers during the recovery phases. Remarkably, agriculture slowed the recovery of the southern regions. Some of these results were induced by the high demographic and economic concentration in the metropolitan region of Santiago. 相似文献
