Abstract

Disease outbreaks and pandemics have long played a role in societal and economic change. However, the nature of such change is selective, meaning that it is sometimes minimal and, at other times, and change or transformation may be unexpected, potentially even reinforcing contemporary paradigms. A comprehensive overview of pandemics and their effects is provided. This is used to help contextualise the COVID-19 pandemic, its impact on tourism and government, industry and consumer response. Drawing on the available literature, factors that will affect tourism and destination recovery are then identified. Some measures will continue or even expand present growth orientations in tourism while others may contribute to sustainability. It is concluded that that the selective nature of the effects of COVID-19 and the measures to contain it may lead to reorientation of tourism in some cases, but in others will contribute to policies reflecting the selfish nationalism of some countries. However, the response to planetary limits and sustainable tourism requires a global approach. Despite clear evidence of this necessity, the possibility for a comprehensive transformation of the tourism system remains extremely limited without a fundamental transformation of the entire planet.  相似文献

Abstract

The unfolding COVID-19 pandemic has closed borders, grounded planes, quarantined more than half of the worlds population, triggered anxiety en masse, and shaken global capitalism to its core. Scholars of the political ecology of disasters have sought to denaturalize so-called “natural” disasters by demonstrating their uneven consequences. Work in the political ecology of health similarly accounts for how risk of illness and disease are socio-economically mediated. While this scholarship has demonstrated the need to contextualize the unequal fallout from ecological and health disasters in ways that reveal the festering wounds of structural inequality, we know much less about how hope is cultivated in moments of crisis. The current revelatory moment of the COVID-19 pandemic offers an opportunity to find hope in the rubble through the deconstruction of framings of crisis as “error” and by homing in on the current and potential role of tourism to contribute to a more socially and environmentally just society. This reframing the pandemic as an "unnatural" disaster opens new debates at the intersection of tourism geographies and political ecologies of hope in revelatory moments of crisis.  相似文献

The tradition of using lime as a binder has been in practice over the centuries and is cited in the architectural feats of all kinds of civilizations. Besides the basic ingredients of lime, sand and water, organic admixtures were also mixed into the mortars to modify fresh and hardened state properties as well as to enhance its durability. The motivation of the present study was to develop a replacement of synthetic admixtures by the bio-admixtures. The plant extract of Cissus glauca Roxb (CGR) which is being used in ancient temples and monuments in Kerala has been tested as admixture in varying concentrations and fermentation periods in lime mortar mix. The admixture is polysaccharide rich and a moisturizing agent.

Tests were conducted to measure changes in microstructure of the mortar; fresh state properties such as setting time and workability, mechanical properties such as compressive strength and flexural strength. Also, physical characteristics of admixture modified mortars such as bulk density, porosity and water absorption were also determined. Morphological analysis using SEM with EDX, mineralogical analysis using XRD and organic analysis adopting FT- IR have been done to validate the results of mechanical and physical tests. Capillary water and salt absorption by suction and resistance to salt crystallization cycles were measured as an indicator of durability properties.

The admixture modified mortar resulted in increased mechanical properties and reduced water absorption. It also limits the capillary rise of water and salt intrusion through the hydrophobic nature. The admixture modified mortar have also offered better resistance against the damaging action of deteriorating salts such as sodium chloride and sodium sulphate crystallization cycles. Polysaccharides and proteins in the plant extract interact with the calcium hydroxide of slaked lime and forms complexes. Hence the, natural polymer has increased the durability of hydraulic lime mortars used for repair and it could be a natural alternative to synthetic admixture.  相似文献

This article explores the entanglement of two kinds of invasive lives in northern Australia: invasive plants, and the enduring life of the unfinished colonial project, which continues to have implications for indigenous peoples. In the extensive indigenous lands of Australia's tropical north, communities have increasing responsibility for invasive plant management among other pressing land management tasks. In a context of climate change and novel ecosystems, these entanglements exacerbate environmental management challenges in the tropical savanna and affect indigenous livelihoods. Drawing on arguments that it is necessary to literally speak novel ecologies, we here enunciate and describe a novel ecological assemblage we call Indigenous Invasive Plant Management (IIPM). Historical accounts and contemporary ethnography (semi‐structured interviews and participant observation undertaken in 2010–2013) show a lingering colonial heritage in the ways that IIPM is entwined with tenure and governance issues, and in its everyday practice. These findings illustrate how IIPM can risk being a form of continuing dispossession as well as having good potential outcomes.  相似文献

ABSTRACT

This article analyzes the proselytical use of ancient theology that developed in the environment of the Jesuit China Mission in the late seventeenth and early eighteenth centuries. This period is roughly coeval with the European diffusion of deistic doctrines based on a secularized interpretation of natural theology. I argue that the threat posed by the spread of such doctrines produced a significant effect on the philosophy that Jesuits developed in order to relate to Confucianism. In particular, in the late seventeenth century, Jesuits belonging to the China Mission gradually abandoned Matteo Ricci’s natural theology and espoused an approach grounded in ancient theology. The situation changed, however, after the turn of the eighteenth century. Deism continued to spread, and even ancient theology came to be perceived as dangerously close the libertinism. The increasing suspicion towards ancient theology was reflected, in the China Mission, by the reception of the doctrines advanced by the so-called “Figurists”, a group of French Jesuits who proposed an interpretation of certain characters of the Chinese Five Classics as figurae of the Bible.  相似文献

ABSTRACT

The 1970s were a period marked by price hikes and fluctuations in the commodity markets, both of which had considerable economic and political repercussions. Although this refers to almost all kinds of raw materials, the case of oil dominates the memory. Metals, by contrast, have received little attention despite their crucial importance for both industrialized consumer states and ore-exporting developing countries. This article develops three main points. First, by highlighting the global metal markets from the late 1960s to the early 1980s it contextualizes the oil-price shock and points out the interactions between the markets for energy and other raw materials. Second, the article aims to draw attention to the sense of crisis in Western industrialized countries regarding their metal supply during this period. This is a topic which has been overshadowed by the case of oil, but which nevertheless deserves study, also because of the parallels to recent developments between 2004 and 2011. Third, the article analyses how notions of resource scarcity, vulnerability and crisis were constructed despite the fact that the commodity crisis proved to be a merely anticipated crisis with high and volatile prices, but no long-term disruptions of supply. Within this article West Germany serves as a case study for highly industrialized, import-dependent countries. The focus is on non-ferrous metals like copper, nickel and aluminium.  相似文献

In investigating ways to reduce community vulnerability to environmental hazards it is essential to recognize the interaction between indigenous and scientific knowledge bases. Indigenous and scientific knowledge bases are dynamic entities. Using a Process Framework to identify how indigenous and scientific knowledge bases may be integrated, three communities impacted upon by environmental hazards in Papua New Guinea, a Small Island Developing State, have established how their vulnerability to environmental hazards may be reduced. This article explores the application of the framework within the communities of Kumalu, Singas and Baliau, and how this could impact upon the future management of environmental hazards within indigenous communities in Small Island Developing States.  相似文献
