Identification of limits and barriers to climate change adaptation: case study of two islands in Torres Strait,Australia 下载免费PDF全文
Communities living on remote islands are often viewed as among the most exposed and vulnerable to climate change impacts. This study uses the Sustainable Livelihoods Framework to investigate how indigenous communities living on two physically different islands in Torres Strait, Australia, experience what they consider to be the impacts of climate change in relation to their daily lives. During this process, a series of natural, physical, and socio‐cultural limits and barriers to climate change adaptation were identified on Boigu, a low‐lying mud island inundated by the sea during high tides and storm surges. As a volcanic island, Erub's elevation is higher but significant community infrastructure, housing, and cultural sites are located on the low coastal fringe. No immediate limits to climate change adaptation were identified on Erub, but physical and socio‐cultural barriers were revealed. Limits to climate change adaptation occur when adaptation actions fail to protect the things valued by those affected, or few adaptation options are available. Barriers to climate change adaptation may be overcome if recognised and addressed but can become entrenched limits if they are ignored. Within the participating communities, such limits and barriers included (a) restricted adaptation options due to limited access to particular livelihood assets; (b) difficulty engaging with government processes to secure external support; and (c) people's place‐based values, which evoke a reluctance to relocate or retreat. 相似文献

The literature on Indigenous participation in the Second World War from Canada, the United States, Australia and New Zealand has tended to portray Indigenous soldiers as exceptionally able and courageous in battle. While heart-warmingly laudatory and an understandable product of genuine evidentiary challenges in researching this subject, the image constructed is partial and unrealistic. At best it is misleading; at worst it conflates indigeneity and combat proficiency in ways that reinforce racial stereotypes of Indigenous people as ‘natural’ warriors prevalent during the war. This article argues that we discard the exceptionalism enshrouding Indigenous combat performance in favour of a more culturally nuanced approach. 相似文献

Poropat, S.F., Nair, J.P., Syme, C.E., Mannion, P.D., Upchurch, P., Hocknull, S.A., Cook, A.G., Tischler, T.R. &; Holland, T. XX.XXXX. 2017. Reappraisal of Austrosaurus mckillopi Longman, 1933 from the Allaru Mudstone of Queensland, Australia’s first named Cretaceous sauropod dinosaur. Alcheringa 41, 543–580. ISSN 0311-5518Austrosaurus mckillopi was the first Cretaceous sauropod reported from Australia, and the first Cretaceous dinosaur reported from Queensland (northeast Australia). This sauropod taxon was established on the basis of several fragmentary presacral vertebrae (QM F2316) derived from the uppermost Lower Cretaceous (upper Albian) Allaru Mudstone, at a locality situated 77 km west-northwest of Richmond, Queensland. Prior to its rediscovery in 2014, the type site was considered lost after failed attempts to relocate it in the 1970s. Excavations at the site in 2014 and 2015 led to the recovery of several partial dorsal ribs and fragments of presacral vertebrae, all of which clearly pertained to a single sauropod dinosaur. The discovery of new material of the type individual of Austrosaurus mckillopi, in tandem with a reassessment of the material collected in the 1930s, has facilitated the rearticulation of the specimen. The resultant vertebral series comprises six presacral vertebrae—the posteriormost cervical and five anteriormost dorsals—in association with five left dorsal ribs and one right one. The fragmentary nature of the type specimen has historically hindered assessments of the phylogenetic affinities of Austrosaurus, as has the fact that these evaluations were often based on a subset of the type material. The reappraisal of the type series of Austrosaurus presented herein, on the basis of both external morphology and internal morphology visualized through CT data, validates it as a diagnostic titanosauriform taxon, tentatively placed in Somphospondyli, and characterized by the possession of an accessory lateral pneumatic foramen on dorsal vertebra I (a feature that appears to be autapomorphic) and by the presence of a robust ventral mid-line ridge on the centra of dorsal vertebrae I and II. The interpretation of the anteriormost preserved vertebra in Austrosaurus as a posterior cervical has also prompted the re-evaluation of an isolated, partial, posterior cervical vertebra (QM F6142, the ‘Hughenden sauropod’) from the upper Albian Toolebuc Formation (which underlies the Allaru Mudstone). Although this vertebra preserves an apparent unique character of its own (a spinopostzygapophyseal lamina fossa), it is not able to be referred unequivocally to Austrosaurus and is retained as Titanosauriformes indet. Austrosaurus mckillopi is one of the oldest known sauropods from the Australian Cretaceous based on skeletal remains and potentially provides phylogenetic and/or palaeobiogeographic context for later taxa such as Wintonotitan wattsi, Diamantinasaurus matildae and Savannasaurus elliottorum.Stephen F.

This paper examines how hockey is used to construct and demarcate the Canadian national community from external others, namely, the USA, Europe and Russia/USSR. The paper suggests popular nationalist narratives around the sport of hockey construct difference from external others in ways that place them in tension with state and corporate interests. Drawing on the concept of everyday nationalism, this article explores how the interplay between international competition, national identity and commercial sport has made hockey an ambiguous and contested national symbol in Canada. 相似文献

On May 31, 2010, Australia instituted proceedings before the International Court of Justice in the case of Whaling in the Antarctic (Australia v. Japan). Although Australian politicians had for some time threatened such a course of action, the decision to proceed with international litigation took many observers by surprise, most basically because Japan appeared to be in a strong legal position and the risks associated with the case appeared greater than Australia's prospects for success. This article examines the background to the whaling dispute and suggests two ways in which litigation in the World Court may contribute to resolution of the dispute no matter the legal outcome of the case. 相似文献

In formulating his understanding of Islamic history, thought and politics, the Turkish Muslim thinker Ahmet Davuto?lu approves and adopts the German philosopher Edmund Husserl's formulation of phenomenology — or, philosophy of consciousness. Both Husserl and Davuto?lu perceive a crisis in humanity and identify its causes in scientism and logical positivism, against which they develop their respective phenomenological alternatives. This article places in parallel Husserl's stylised history of Western thought and Weltanschauung method with that of Davuto?lu's Muslim worldview, in order to illuminate the latter's putatively comprehensive interpretation of Islam, diagnosis of the ills of secularism, modernisation, and crisis of values he finds in Muslim societies; and his prescribed treatment for those ills: the privileging of ontology over epistemology, and the full unfolding of core theological concepts of revelation, monotheism, and prophecy. Davuto?lu seeks to reconcile tensions and disputes within Islamic intellectual traditions concerning the nature of God and God's attributes, and the tension between mysticism and rationalism, and the historical and the atemporal. In summary, Davuto?lu's intervention in Islamic traditions is interesting in the effort it makes to appropriate elements of both Husserl and GWF Hegel for the purpose of reconciling a phenomenological reading of Islam with established Islamic authorities and commitments. 相似文献

Hurricanes Katrina and Felix made landfall in 2005 and 2007 on the Gulf Coast of the US and the Atlantic Coast of Nicaragua respectively. Despite many economic, political and cultural differences between these two sites, they share a number of interesting similarities. Their inhabitants are subject to similar modes of racialized Othering and internal colonialism, and both places have vital links with the transnational cultural consciousness that Gilroy referred to as the Black Atlantic. Katrina and Felix also occurred at a time when centralized forms of media are increasingly perceived to be in crisis. This crisis is creating new spaces for the development of alternative ways of knowing, watching and making media. This paper draws on recent literature on decolonization by Mignolo, Escobar, Quijano and others to explore the prospects for decolonizing energies within the new media environment and a context of devastation wrought by neoliberalism and disaster. This research examines disasters in/and the new media environment, and suggests that activists should understand the distinctions between mainstream (or corporate) and alternative media, between top‐down and grassroots media, and between “old” and “new” media, in relational and non‐categorical rather than absolute terms. These media realms should be engaged from an awareness of how they interact with and impact upon one another. This research also suggests that disasters must be understood as ongoing and open‐ended events embedded within historical, social, cultural, economic and political processes and systems. Media, policymaking and emergency management practices that are informed by an awareness of this complex embedding, and which are therefore able to take a long‐term view of the unfolding of disasters, will be best equipped to engage effectively, and in democratically responsive ways, with disasters and in particular with the needs of those populations most vulnerable to their impacts. 相似文献
