In recent years, cultural anthropologists have made notable progress in understanding the bewildering variety of material exchange transactions found among the aboriginal populations of highland New Guinea. One of the major findings of this work is that competitive exchange behavior may bring in its wake alterations in agronomic practices involving an intensification of production. That intensification is primarily a product of social behavior, rather than an adaptation to climate change or population pressure, is a significant conclusion that should influence the thinking of archaeologists as they investigate past episodes of agronomic change, including the origins of agriculture.  相似文献

This paper argues that indigenous peoples' responses to climate change are better understood in relation to emerging notions of citizenship than to climate change crisis narratives. The latter, like development narratives, are often used to license the intervention of experts in debates about resource management and conservation. Dominant climate change narratives about the Arctic emphasise the power of global climate systems to threaten northern communities by situating them as being intrinsically ‘at risk’. These narratives envisage Arctic citizenship within very narrow parameters which have largely masked the voices of northern citizens. Definitions of ecosystem resilience, while providing a framework for comparing disparate cultural and ecological contexts, are predicated on avoiding systemic collapse. It is argued that such definitions heighten the sense of risk implicit in climate change impacts. This may ultimately impede the development of different aspects of civic participation by northern citizens with climate change policy opportunities. Policy responses across a range of diverse geographical contexts require new narratives that put communities back into the calculus of risk and decision-making. One way to be more critical about the language of climate change narratives is to evaluate the extent to which they can account for, and mitigate, growing inequalities of power and wealth. Studies in the historical reception of science narratives are proposed as a better approach for making grounded comparisons of the discursive strategies with which climate change narratives are made to work. This also helps to bridge discussions of climate change across regions like the Arctic and Africa, which share much in common, but are too often studied in isolation.  相似文献

This paper introduces a special feature on narratives of climate change, containing papers by Richard Hamblyn, Sverker Sörlin, Michael Bravo and Diana Liverman. The feature reflects the rising cultural profile of climate change in the public sphere, as represented, for example, by Al Gore's documentary film, An Inconvenient Truth, and art exhibitions devoted to the subject.  相似文献

Newly created academic programs at Brazilian universities have provided the impetus for new archaeological projects in southeastern South America during the last two decades. The new data are changing our views on emergent social complexity, natural and human-induced transformation of the landscape, and transcontinental expansions and cultural interactions across the Río de la Plata basin during the Middle and Late Holocene. We concentrate on six major archaeological traditions/regions: the Sambaquis, the Pantanal, the Constructores de Cerritos, the Tupiguarani, the Southern Proto-Jê, and the middle and lower Paraná River. Diverse and autonomous complex developments exhibit distinct built landscapes in a region previously thought of as marginal compared with cultural developments in the Andes or Mesoamerica. The trajectories toward increased sociopolitical complexity flourished in very different and changing environmental conditions. While some groups were pushed to wetland areas during a drier mid-Holocene, others took advantage of the more humid Late Holocene climate to intensively manage Araucaria forests. The start of the second millennium AD was a critical period marked by an increased number of archaeological sites, the construction of ceremonial architecture, and the intensification of landscape transformation; it also was marked by the rapid expansion of influences from outside the La Plata basin. The Amazonian Tupiguarani and Arawak newcomers brought with them significant changes in technologies and social and political structures, as well as novel landscape management practices.  相似文献

历史学者总是臆断人类生活在自然世界之外。环境史质疑这种假设,并且坚持人类是自然的一部分,我们对自然施加着影响,同时自然也对我们具有影响。这种新的观念聚焦在三套相互作用的变化之上:地球的各种系统(气候、地理、生态系统)伴随时间的变化,自这些系统中谋求生计的生产模式的变化,以及文化态度的变化及其在艺术、意识形态、科学和政治中的表现。这门新的历史学在其方法上是跨学科的,而在其含义上是跨国界的。  相似文献

In the fourth millennium BP, there were major environmental and cultural changes on the Andean altiplano of South America, but the chronology remains vague. A recent synthesis describes a slow, gradual transition from hunting and gathering to agropastoralism. This proposal is tested by refining the date of the onset of more humid and stable conditions, around 3550 cal BP, based on a Bayesian model of 26 dates from Lake Wiñaymarka and an updated calculation of the lacustrine offset. This is compared to Bayesian models of 191 dates from 20 archaeological sites, which incorporate a number of recently processed radiocarbon dates. A synthesis is presented of 15 full coverage surveys, a summed probability distribution, and a Bayesian model of the transition to ceramics, which together support a scenario of a very rapid demographic increase. Fourteen models from archaeological sites are cross-referenced in a composite model, which identifies a brief, altiplano-wide emergence of agropastoralism with starting and ending boundaries of 3540 and 3120 cal BP, respectively. This starting boundary correlates strongly with the onset of improving environmental conditions, indicating synchronous cultural and environmental change. The suite of accelerating cultural changes included a marked reduction in mobility, a demographic surge, increased subsistence diversity, the adoption of ceramics, farming and the integration of camelid herding into a remarkably resilient economic strategy still in use today. This is a highly relevant but yet to be used comparative case study for the variable tempos of ‘big histories’, and ecocultural interactions that generate rapid, emergent episodes of wide-spread and enduring cultural change.  相似文献

As green infrastructure (GI) plans are being developed and implemented in a number of regions throughout the UK and interest in the theory and methods is emerging in various other countries there is opportunity to explore the potentials for GI planning throughout Europe. Using the experience of the UK, and particularly that of stakeholders and organizations in the North East of England, we analyse the functions and benefits that a GI network can provide and, through cross-national comparison, we critically theorize the potentials for GI planning in Catalonia. While recognizing that there are key differences between these regions, particularly in relation to climate, societal characteristics, institutional organizations and frameworks for landscape planning, we discuss the transferability of the characteristics which appear to be provided from GI planning in the UK. We conclude that, overall, the implementation of GI planning would be relatively easy to achieve and mostly beneficial under a Mediterranean environment. Our conclusions are tempered by a recognition that the provision of functions and benefits are subject to the influence of the particular organizational characteristics and the cultural background of each region, and in particular the different impacts that climate change is likely to have.  相似文献

唐代长安、洛阳作为都城和陪都的气候原因   总被引:4,自引:0,他引:4  
本文从气候角度探讨唐代以长安为都城、以洛阳为陪都的缘由。唐代由于气候温暖湿润,降水量增大,水灾增多。洛阳因为经度地带性作用、降雨季节分配不均及洛阳河流的特殊情况。使得水灾情况比长安更严重:一是降水量大、水灾次数多,二是水势大、灾情重。尽管唐政府注意治水修堤坝,但中桥被冲毁、雨水断路乃至宫城被淹之事仍屡屡发生。长安虽然旱灾较洛阳严重,但水灾对都城的危害更直接、更严重,灭顶之灾的威胁使洛阳不宜作都城,所以建都长安。  相似文献

ABSTRACT

Kettle Falls, located 1125?km from the mouth of the Columbia River in present-day Washington State (USA), was the second-most important salmon fishing and trading locus on that river in the early historic era. We encapsulate the late Holocene history of the fishery by deriving a summed probability distribution function (SPDF) from 50 radiocarbon ages from 13 archaeological sites within 2?km of the falls. When compared to an SPDF from 307 sites from elsewhere on the Columbia Plateau, and a null model, the Kettle Falls SPDF exhibits two phases of elevated activity at 1700–1300?cal BP and 800–500?cal BP, and an intervening lull. These phases are not related to the excavation history or differential exposure of sites to taphonomic processes, but they are concordant with episodes of glacial advance in the local mountains, which reflect hemispheric-scale changes in climate. Modern returns of summer-run Chinook salmon to the Columbia River are inversely correlated with sea-surface temperature regimes in the northeast Pacific Ocean, and we propose that the occupational history of the Kettle Falls fishery echoes long-term variations in the returns of salmon to the upper Columbia River linked to climate change.  相似文献

San (Bushman) society in the Cape Colony was almost completely annihilated during the eighteenth and nineteenth centuries as a result of land confiscation, massacre, forced labour and cultural suppression that accompanied colonial rule. Whereas similar obliterations of indigenous peoples in other parts of the world have resulted in major public controversies and heated debate amongst academics about the genocidal nature of these episodes, in South Africa the issue has effectively been ignored aside from passing, often polemical, references to it as genocide. Even recent studies that have approached the mass killing of the Cape San with sensitivity and insight do not address it as a case of genocide. This article sets out to redress this imbalance in part by analysing the dynamic of frontier conflict between San and settler under Dutch colonial rule as genocide. It demonstrates both the exterminatory intent underlying settler violence as well as the complicity of a weak colonial state in these depredations, including its sanctioning of the root-and-branch eradication of the San.  相似文献

Climate change is expected to have a severe impact on cultural heritage in the future. This study presents the methodology developed during the FP7 project Climate for Culture, of assessing the climate change impact on collection objects in cultural heritage buildings. The main innovation lies in coupling new high resolution future climate projections with building simulation tools in order to predict future indoor climate and identify future risks in historic buildings. The case study is an intermittently heated wooden chapel in Croatia. The whole building simulation model of the chapel was validated using a newly developed method of accuracy assessment in the context of preventive conservation. Even though modeling intermittent heating induces limitations in the model, it can be used for computing of future indoor data. Future indoor climate data was assessed for possible risks of biological, mechanical, and chemical damage to painted wooden panels using the newly developed specific climate risk assessment. When using this method of damage assessment on buildings with active climate control, especially with intermittent heating, it is recommended to determine the relevant season for the damage process in order to objectively analyze results.  相似文献

This article offers a chronology of climate events in Iran over the last millennium to challenge traditional chronologies of the Iranian past based on politics, war, and economics. Using insights gleaned from the historiography of climate in Iran, and from neighboring regions, especially the Ottoman Empire, four episodes of climate cooling show how climate-induced environmental processes affected more people for longer in Iran than did the policies of the empires ostensibly ruling over them. Thus, the article aims to put climate more squarely on the agenda of historians of Iran so that the conjectures advanced here can be confirmed, revised, or discarded through future empirical research. Moreover, the article seeks to bring Iran into wider conversations in environmental and global history.  相似文献

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

慈利白公城遗址历史悠久,具有重要的考古价值。该遗址出土了大量木质井壁及少量其他木质文物,为了解这些木材的特点,以及为木材保护提供相关的参考,通过徒手切片,并利用光学显微镜对该遗址出土的10件木质样品进行鉴定。结果表明其中1件为无患子(Sapindus. mukorossi Gaertn.),1件为冷杉(Abies fabri(Mast.)Craib),2件为湖南杨桐(Adinandra. acutifolia Hand.-Mazz.),2件为香椿(Toona sinensis A. Juss.),4件为润楠(Machilus pingii Cheng ex Yang)。通过实验结果,初步推测井壁的制作在当时是比较重要的工作,此时已经在选择性地使用木质井壁原料。从树种适宜生长的环境上看,同时期该遗址附近可能是以阔叶材为主的针阔叶混交林,气候温暖湿润。  相似文献

Abstract

In the Sustainable Development Goals adopted by the United Nations in 2015, the role of culture is limited. We argue that culture’s absence is rooted in the longue durée of interplay among theoretical and policy debates on culture in sustainable development and on cultural policy since the mid-twentieth century. In response to variations in concepts and frameworks used in advocacy, policy, and academia, we propose four roles cultural policy can play towards sustainable development: first, to safeguard and sustain cultural practices and rights; second, to ‘green’ the operations and impacts of cultural organizations and industries; third, to raise awareness and catalyse actions about sustainability and climate change; and fourth, to foster ‘ecological citizenship’. The challenge for cultural policy is to help forge and guide actions along these co-existing and overlapping strategic paths towards sustainable development.  相似文献
