The Indian Ocean tsunami (IOT) of December 2004 has demonstrated that the coasts of Australia are vulnerable to tsunami flooding.
As a consequence of the IOT, the Australian Federal Treasurer announced in 2005 that the Bureau of Meteorology and Geoscience
Australia will jointly develop and implement the Australian Tsunami Warning System. Effective response to tsunami warnings
is highly dependent on public awareness and perception of tsunami hazard and risk. At present, no efforts have been made to
investigate and publish public awareness of tsunami hazard and risk and as such, emergency managers have little idea of the
likely challenges to effecting appropriate tsunami risk management. We develop a short questionnaire survey instrument and
trial that instrument in order to investigate its suitability for generating information about the perceptions of tsunami
hazard and risk in the Sydney region. We found that the design, layout and format of the questionnaire were suitable for our
purpose and should be useful for generating information appropriate to emergency management agencies tasked with the responsibility
of developing tsunami education campaigns and risk mitigation strategies in Australia. However, certain limitations, such
as individual question design and format, should be considered before a much larger survey of various stakeholders is conducted. 相似文献

We assess women’s perceptions of health risks in relation to quality of life concerns, with attention to variables viewed as central to maintaining or improving health and well-being. In this paper, we specifically underscore how a life-threatening disease—malaria—is experienced and bio-cyclically understood and managed in relation to seasonal hunger, food insecurities, and livelihood vulnerabilities. The study, conducted June–July 2013, draws on field data and interviews with 60 women farmers of the Luhya community along the Yala River in Kakamega County, Western Province, Kenya. Major findings suggest the following: (1) women’s perceived desired quality of life is shaped by priorities for children’s education, nutrition, food security, and economic security in their rural communities; (2) malaria emerged as a challenging household health problem that curtails livelihood opportunities for most study participants; and (3) local understandings of malaria transmission, particularly how and when female mosquitoes become infected with malaria-causing protozoans, was low, but malaria symptoms were relatively well-understood. The interest and motivation to institute new malaria risk reduction practices at the community level are explored, including attention to building upon the Luhya tradition of oral storytelling in order to promote actions to eliminate malaria. This analysis of local narratives of health risks illustrates these points and demonstrates how women’s constructions of health risks and well-being provide a basis for developing interventions targeting income generation and microloan opportunities that could support Kenyan women in their intersecting approaches to malaria, securing nutritious diets, and enhancing the local health environment. 相似文献

This paper is based on 6 months of ethnographic, multi-sited research in Malaysia, and investigates the relatively recent phenomenon of edible birds’ nest farming in urban areas (‘swiftlet farming’). Swiftlet farms are typically converted shophouses or other buildings which have been modified for the purpose of harvesting the nests of the Edible-nest Swiftlet (Aerodramus fuciphagus). I use the controversy over urban swiftlet farming in the Malaysian city of George Town, Penang, to examine discourses used by key stakeholders to shape debates over the place of non-human animals in cities. By considering everyday experiences of urban swiftlet farming, I explore how this burgeoning industry is perceived amongst residents, and how it is deemed to be (in)appropriate within the political, economic and cultural landscape of George Town. Yet, I also consider how farmers have sought to contest these discourses on ideological and normative grounds. In so doing, I place the cultural animal geographies literature in conversation with emergent literature on landscape and urban political ecology. Such a framing allows for a critical evaluation of the controversies surrounding this case, and their implications for human-animal cohabitation in cities. The paper reflects on the implications of this case for how we regulate human-animal relations and live in contemporary cities, and the crucial role of animals in altering urban form, aesthetics and everyday life, particularly in non-Western contexts. 相似文献

Communities have increasingly been internalised as subjects with responsibilities in the delivery of urban policy and involvement in broader urban governance. A prominent example is the English New Deal for Communities (NDC) programme that ran between 2001 and 2012. Towards the end of government funding, NDCs were required to develop succession strategies that would leave a ‘legacy’ for their communities. This involved the development of social enterprise bodies that would continue to support community involvement and regeneration efforts through ownership of capital assets, acquisition of public service contracts, and partnership working with mainstream service providers. This paper examines the influence of communities on post-NDC bodies, and the relationship between these organisations and local government, which was a critical agent in the management of the previous NDC bodies. The ‘recognition’ perspective of Honneth (1995), which is concerned with the self-actualisation of actors through inter-subjective relations based on forms of recognition (e.g. respect), is deployed in the analysis of post-NDC bodies. The paper concludes that long term community representatives’ have incorporated market values as a means in which to acquire ‘respect’ from social enterprise professionals, and that there is a lack of recognition by state agents of the role of post-NDC bodies in contemporary urban governance. 相似文献

This article examines young Peruvians’ aspirations and the role of migration in their imagined futures, from a generational perspective. The data come from Young Lives, a long-term study of childhood poverty combining survey and qualitative approaches with children and their parents. The paper uses a biographical approach that sees migration as part of individual biographies as well as social structures and life course processes. The aim is to deepen understanding of the social contexts in which aspirations for and by children are generated, paying close attention to family migration histories, dynamic household contexts, and children’s migration networks. The analysis focuses on the time-spaces of migration aspirations, showing the way past, present and future are interconnected. It also emplaces aspirations by focusing on the way aspirations by and for children are constituted in and through particular places. The conclusion reflects on the role of poverty and argues that ‘aspirations’ are about much more than abstract ‘futures’; they orient actions in the present and say a great deal about young people’s current realities and relationships. 相似文献

Kahoolawe volcano (~10×17 km) forms one of the eight major Hawaiian islands. Access for geologic sampling has long been restricted due to military and preservation policies. However, limited visits to Kahoolawe in the 1980s yielded >200 samples, many of which have since been used to study the volcano within the framework of Hawaiian shield and mantle source geochemistry, petrology, mineralogy, and igneous processes.Kahoolawe is a tholeiitic shield with tholeiitic caldera-filling lavas, and at least seven postshield vents that erupted tholeiitic and (sparse) alkalic lavas. On smaller scales are a gabbro intrusion and ultramafic and gabbroic xenoliths in some postshield lavas. There is no evidence for rejuvenated volcanism. In its structural setting, Kahoolawe lies along the “Loa” trend of Hawaiian shields.Major element compositions of shield and caldera-filling lavas are similar and cluster at ~6–7 wt% MgO, range from ~5.5 to 16 wt% MgO, and include ~9 wt% MgO examples that can be modeled as parental to the evolved lavas. For example, least squares mass balancing demonstrates that from ~15% to 30% crystallization of olivine (±orthopyroxene), clinopyroxene, and plagioclase accounts for the ~5.5–6 wt% MgO range of tholeiitic lavas. Greater differentiation occurred in the gabbro (diabasic) intrusive body as a segregation vein with ~2.9 wt% MgO, and extreme differentiation produced local, small-volume rhyolitic melts that segregated into lava vesicles. Postshield lavas are mainly tholeiitic, have ~5–7 wt% MgO, and overlap shield compositions. Some are alkalic, as low as ~3.9 wt% MgO (hawaiite), and can be modeled as liquids after a ~9 wt% MgO alkalic magma crystallized ~30% olivine, clinopyroxene, plagioclase, and magnetite.Important aspects of Sr, Nd, Hf, and Pb isotopic ratios in Kahoolawe shield and caldera-filling lavas are slightly higher 87Sr/86Sr than in Koolau shield lavas (Oahu island; Makapuu-stage; e.g., Koolau mantle ‘endmember’) when compared at a given 143Nd/144Nd (e.g., ~0.7042 at 0.5128), 206Pb/204Pb largely at the low end of the range for Hawaiian shields (e.g., ~18), and εHf generally comparable to the values of other Hawaiian shields and ocean islands (e.g., εHf 8 at εNd 4). The isotopic ratios overall suggest small-scale source heterogeneity, considering the island size, and that Kahoolawe shield and caldera lavas were derived from a Hawaiian plume source containing recycled oceanic crust of gabbro and sediments. Based on certain geochemical indicators, however, such as Ce/Sr and La/Nb vs. 87Sr/86Sr, the source contained slightly less gabbro component than other shield sources (e.g., Koolau). Isotopic data for Kahoolawe postshield lavas are scarce, but those available generally overlap the shield data. However, ratios among certain alteration-resistant incompatible trace elements (e.g., Zr/Nb) discriminate some postshield alkalic from shield lavas. But because the different ratios for those postshield lavas can be explained by smaller partial-melting percentages of the shield source and by differentiation, neither isotopes nor trace elements identify postshield magmas as originating in a source unlike that for the shield lavas. 相似文献

This paper examines the enduring separation and isolation of elite schools in England, in the face of increasing and substantial internationalisation. It presents the findings of a research project examining the geographical narratives produced by 30 elite schools on their websites and through their prospectuses, newsletters, blogs and twitter feeds. A critical visual and textual analysis was undertaken. Drawing on these data, the paper argues that elite schools remain highly focused on promoting and defending their separateness and isolation, despite extensive, documented international involvements. Work on institutional and carceral geographies and geographies of education have provided some theoretical justification for why this might be the case, and we explore these reasons here. The paper concludes with a plea for more work on the elite schooling sector in England, as their spatial practices (isolation and internationalisation) continue to have a weighty bearing upon society. 相似文献

Bringing together ethnographic evidence from mid-Western Nepal and eastern Sri Lanka, this article explores how political legitimacy is constructed and contested in post-war environments. We posit that in the post-war context there are important changes in the kinds of politics, agenda-setting, players and tactics that are considered acceptable and those that are rendered transgressive, threats to order and stability, or otherwise placed ‘out of bounds’. The art of crafting political legitimacy is defined in sharp contrast to the immediate history of armed conflict. The end of the war and the resumption of supposedly democratic politics thus mark a shift in what is seen as legitimate or normal politics. This shift constrains certain kinds of actors, tactics, and registers and it amplifies others, while being itself a result of political work. We argue that a reduction of the space for dissent, and an increase of the space for politicking are complementary aspects of the redefinition of what constitutes legitimate politics in the post-war context. These adverse political effects are not simply problems of context – post-war environments being non-conducive to democracy – but rather expose the more fundamental fallibilities and contradictions of demarcating a legitimate sphere of democratic politics in particularly visible and precarious ways. 相似文献

What is ‘good food’? Is it fair trade, local, organic or ethically produced? With an ever-expanding array of products and ‘qualities’ to consider, consumers in the global North may find it increasingly difficult and time-consuming to make the ‘right’ choices. As a result, a range of intermediaries, including food apps and collective buying groups, are emerging to support and influence people with their food choices. While intermediation refers to all activities linking producers and consumers, this paper narrows the focus and considers one important, yet poorly understood, intermediary function within the food marketplace: ‘curation’. Although the concept of curation has long been associated with museums and art worlds, curatorial practices are evolving in the contemporary marketplace and are performed by a growing range of actors operating in physical, temporary and virtual spaces. Rather than acting as brokers or gatekeepers, curators interpret, translate and shape the marketplace by sorting, organising, evaluating and ascribing value(s) to specific products. They also offer general and personalised recommendations to consumers. Although the literature on local food privileges the direct relations between producers and consumers, this paper considers the important role of intermediaries. Drawing on interviews and participant observation in Sweden it contributes to the existing literature on curation by examining the spatial dynamics and nature of curatorial practices, the motivations behind them and the values they create for consumers. The findings demonstrate that a range of activities can be understood as curation and that in order to nuance and extend existing conceptualisations of curation a wider and more dynamic range of actors (food apps), spaces (blogs) and values such as inspiration, convenience and sense of community need to be considered. 相似文献

Indian metropolises have witnessed the growth of ‘new towns’ on their peripheries over the past two decades, which have attracted investment as well as affluent residents. Most research on new towns examines the contentious politics of land acquisition and development, but less is known about urban governance and everyday life. This article focuses on solid waste management in Noida, a new town on the periphery of Delhi that has been unable to develop a large-scale waste management system, and we have two main foci. First, we show that the municipal government has sought to regulate waste collection, while waste processing and disposal have remained unregulated and this has discouraged the entry of medium and large-scale private enterprises. Second, we explore the contentious politics surrounding actually existing waste management practices that have emerged in the absence of significant public or private investment. Most waste is managed by small- and medium-sized enterprises in the informal sector, so associations that represent the so-called ‘new’ middle class must interact with informal-sector waste workers. These interactions result in moderately high levels of waste collection but waste disposal remains haphazard and this exposes the limits of the new middle class’ control over urban space. Ultimately, we show how municipal governance and the actually existing politics and practices of waste management contribute to the production of Noida’s socio-spatial landscape. 相似文献

Motorised transport infrastructure and increasingly specialised labour markets have resulted in energy intensive commuter patterns in many parts of the world. This is cause for concern due to the possibility of oil price shocks and the need to restrict the combustion of fossil fuels to minimise the chances of runaway climate change. The paper investigates methods to identify the spatial distribution and socio-demographic profiles of those who are vulnerable to high oil prices. It does this by use of four metrics of oil vulnerability which were developed using a spatial microsimulation model and applied to the case study region of Yorkshire and the Humber, UK. The metrics capture different aspects of vulnerability and highlight the importance of translating conceptual definitions into practical metrics. The geographically aggregated results coincide with the literature: rural areas are associated with the highest levels of vulnerability. The individual level results indicate that vulnerability can be prevalent even in seemingly resilient areas. Ultimately, we conclude that the social and spatial distribution of oil vulnerability depends on how an energy-constrained future is envisioned. Creating localised metrics about the future is a challenging task fraught with danger but could, provided that these metrics are interpreted with sufficient humility, aid the development of equitable policies to encourage resilience, as part of a worldwide transition away from fossil fuels. 相似文献

In East Africa, financially strained governments increasingly experiment with voluntary, market-based carbon offset schemes for enhancing the public management of protected areas. Often, conservationists and governments portray these as ‘triple-win’ solutions for climate change mitigation, biodiversity preservation, and local socioeconomic development. Examining such rhetoric, this paper analyses the rise and decline of an integrated carbon offset and conservation initiative at Mount Elgon National Park in eastern Uganda, involving a partnership between the Uganda Wildlife Authority (UWA) and a Dutch NGO, Face the Future. In doing so, the paper reveals the ways in which the uncompensated dispossession of local residents was a necessary precondition for the project’s implementation. Although external auditors expected the project to sequester 3.73 million tons of carbon dioxide equivalent (tCO2e) between 1994 and 2034, conflicts forced the scheme to cease reforestation in 2003. Noting this rapid decline, we problematize the ways in which Face the Future and other carbon market intermediaries represented their activities via project documents and websites, obscuring the violence that was necessary for the project’s implementation. In so doing, we argue that the maintenance of a ‘triple win’ spectacle is itself integral to the management of carbon sequestration projects, as it provides consumers with a form of ‘ethical’ use value, and greatly enhances the capacity of carbon market brokers to accumulate exchange value by attracting ‘green’ investors. Consequently, what we term a ‘spectacular failure’ manifests in at least two ways: first, in the unravelling of the heavily mediatized spectacle of harmonious, profitable conservation, and, second, in the deleterious nature of the consequences that accrue to local communities and ecosystems alike. 相似文献

Many glaciated valleys in Scotland contain distinctive, closely spaced ridges and mounds, which have been termed ‘hummocky moraine’. The ridges and mounds are widely interpreted as ice-marginal moraines, constructed during active retreat of mainly temperate glaciers. However, hummocky terrain can form by various processes in glacial environments, and it may relate to a range of contrasting glaciodynamic regimes. Thus, detailed geomorphological and sedimentological studies of hummocky surfaces in Scottish glaciated valleys are important for robust interpretations of former depositional environments and glacier dynamics. In this contribution, we examine irregularly shaped ridges and mounds that occur outside the limits of former Loch Lomond Readvance (≈ Younger Dryas; ~ 12.9–11.7 ka) glaciers in the Gaick, Central Scotland. These ridges and mounds are intimately associated with series of sinuous channels, and their planform shape mimics the form of the adjacent channels. Available exposures through ridges in one valley reveal that those particular ridges contain lacustrine, subglacial, and glaciofluvial sediments. The internal sedimentary architecture is not related to the surface morphology; thus, we interpret the irregularly shaped ridges and mounds as erosional remnants (or interfluves). Based on the forms and spatial arrangement of the associated channels, we suggest that the ridges and mounds were generated by a combination of ice-marginal and proglacial glaciofluvial incision of glaciogenic sediments. The evidence for glaciofluvial incision, rather than ice-marginal moraine formation, at pre-Loch Lomond Readvance glacier margins in the Gaick may reflect differences in glaciodynamic regimes and/or efficient debris delivery from the glacier margins to the glaciofluvial systems. 相似文献
