Scottish peatlands are now recognised as important habitats for conservation, and are increasingly protected by both national and international designations. This paper examines peatland conservation in north‐east Scotland, using recently published data to assess habitat quality, and relating this to longer‐term historical trends in attitudes towards peatlands, and their utilisation. The historical data indicates that peatland losses in northeast Scotland have been extensive, and occurred rapidly during the 18th and 19th centuries, when peatlands were regarded as fuel sources, or wastelands which could be converted to agricultural use. Threats have lessened in the second half of the 20th century, and many sites are now protected by conservation designations. However, historical attitudes towards peatlands often persist, and this can pose problems which must be addressed if conservation management is to be successful.  相似文献

Simplistic interpretations of the impact of newcomers on South American ecosystems retain currency in the environmental history of the subcontinent. European settlement is almost invariably seen to produce a continuous and linear destruction of the environment. On the basis of several crisis narratives contained in historical documents, it is widely accepted that there was a severe decrease in the extent of woody vegetal formations in the Río de la Plata area during the 19th and 20th centuries. To test this perception, and to develop a more accurate and more complex analysis of the environmental consequences of European occupation, this article focuses on Uruguayan territory from c. 1800 to 2000. Changes in the shape and extent of forest lands in this broad area were assessed by comparing 251 land-survey charts, drawn between 1830 and 1860, with modern-day forest maps. Changes in shrubland abundance were assessed by comparing current distributions with those inferred from the accounts of five travellers who passed through this territory in the first half of the 19th century. Over 200 years, there is no evidence of major changes in forest distribution, extent or shape, and shrublands appear to be much more abundant today than in the early 19th century. These observations, although based on limited data, contradict the most common interpretation of regional environmental evolution. They confirm other claims that the idea of forest destruction in the early 19th century was created and manipulated by actors involved in land conflicts. Close examination of such socially-constructed crisis narratives, through the use of new archives, leads to a better understanding of recent changes in the South American environment.  相似文献

The nineteenth century in France marked the origins of modern forest management. Two important dates mark the advent of the organisation of forestry: first in 1824, the creation of the Forestry School in Nancy, and then in 1827 the adoption of a Forestry Code specifying to what extent forests were to submit to the forestry regime. Throughout the nineteenth century, forestry administration crystallised the resentment of village communities in the Montagne de Lure through the increasingly strict management of activities linked to the forest. During the 1800s almost all foresters, with a few exceptions, claimed they were the ones who knew the truth and represented collective interests against local populations that they judged to be ignorant and not very concerned with the future. The policy of Restoration of Mountain Terrain (RTM) that was put in place in the Montagne de Lure near the end of the nineteenth century marks the outcome of such a process. It reflects the power of the centralised body of forestry engineers over forest management in France and the decline of local communities, weakened by massive rural depopulation and by a succession of economic crises. Forest space therefore crystallises during these decades of dispute between local and central power.  相似文献

Both, astronomy in the first half of the 19th century and physics in the second half of the 19th century functioned as models and paradigms for the other sciences. The paradigmatic character of a theoretical, mathematical astronomy was due mainly to its capability to predict future events. According to the influence of the Romantische Naturphilosophie the mathematization of physics in Germany took place belatedly compared to France. A modified Newtonian research program with its mathematical implications was adopted by German physicists only after the establishment of the principle of energy conservation. German physicists of the late 19th century claimed over and above the results of physicists the successes of German technology for physics and interpreted these achievements as “cultural” achievements. They combined this claim with a request for a better representation of physics in the curricula of secondary schools so as to be comparable to that of mathematics. The resistance of the most prestigious secondary schools, the Humanistische Gymnasien, against this request meant that the concept of Bildung as propagated by physicists was not accepted generally in Germany.  相似文献

Mont Lozère, located in the French Massif Central region, provides an exceptional context in which to research the impact that charcoal production and metallurgy had on woodlands, along with the role that these activities played in changing the mountain landscape. This study provides an insight into the land use, forest management methods and metallurgical practices in the area during the Middle Ages (11th to 15th centuries). Medieval charcoal burning platforms, archaeological remains that have often been neglected in the past as a source of historical information, along with nearby smelting sites, were identified, sampled and analysed. In this paper, spatial analyses, radiocarbon dating and anthracological and dendro-anthracological studies have been combined in a unique manner. The results reveal that charcoal burners practiced beech coppicing, where the species and diameter of wood used remained the same over a period of four centuries. It is proposed that this form of metallurgical forest management be considered an early example of a sustainable utilisation of natural resources.  相似文献

Community forestry is thought to diffuse the kind of tensions over access to resources that frequently make centralized forest management systems based on the principles of scientific forestry ineffective and conflictive. Centralized systems often create resistance, as communities whose vegetation management practices have been declared illegal by forest bureaucracies anonymously contest the restrictions imposed on them by ‘stealing’ trees and committing ‘arson’. These restrictions are intimately related to the requirements of scientific forestry, however, so co‐management strategies relying on scientific forestry might also engender various forms of internal resistance, such as tree theft. Local interpretations of justice in access to resources, together with community social structures and the distribution of resources can result in internalized resistance, rendering community‐based resource management ineffective. In a Mexican community case‐study, scientific forestry and tree theft co‐evolved during a period of concessions and continue under co‐management. This system creates an arena where anonymous individual resistance like tree theft can give way to forms of protest more likely to result in legitimate and effective forest management systems.  相似文献

The second half of the 19th century, along with the first three decades of the 20th, saw the building of hundreds of flour mills in Spain, all based on new milling and sieving machinery developed after the industrial revolution. Unfortunately, very few of these early mills are now in use: most have disappeared, and many of those that are left have been abandoned. The present work examines the growth of the flour-milling industry in Spain from the mid-19th century, and discusses the typology, design and constructional features of its associated buildings. The information presented is the result of the study of a representative sample of these mills in central Spain, and could serve as a basis for the conservation, rehabilitation and reuse of this important agroindustrial heritage.  相似文献

During the second half of the 19th century, Spain's industrialgeography underwent radical change. In Jordi Nadal's words,‘Catalonia became Spain's factory’. This gradualgeographical concentration of industrial activity coincidedwith another process: the integration of the Spanish economy.The purpose of this paper is to analyse the determinants ofthe localization of industrial activity in Spain during thesecond half of the 19th century and the effects of economicintegration on Spain's industrial geography. To this end, wefirst review the historical analysis of these changes and presentevidence on the process of market integration and industrialconcentration by constructing a range of measures of industrialspecialization and geographical concentration. Second, we performan econometric analysis of the determinants of industrial locationat two points in time, 1856 and 1893, using spatial econometricstechniques. Our results are consistent with the hypotheses oftrade theories. During the second half of the 19th century,Spain became an integrated economy and industrial activity wasconcentrated in a limited number of territories characterizedby a comparative advantage in human capital endowments, a favourablegeo-economic position, and initial specialization in sectorsshowing scale economies.  相似文献

Early forestry surveys of Papua and New Guinea can be understood as records of cross-cultural encounters. I argue these records are very much concerned with the social context of data production and as such provide interesting insights into the history of colonial forestry. Relying largely on the work of Lane-Poole, this essay examines his accounts of colonial intercultural communication, his own changing, at times inconsistent, understandings of such processes and his limited capacity to represent them. His innovative, yet also anachronistic, work combines elements of the travel writing of the 19th century naturalist with the more austere data requirements of the kind of scientific forestry that he was attempting to create in Australia, Papua and New Guinea. I use his surveys, and those of his predecessor, Burnett, to outline the difficulties they encountered as co-ordinators of communicative transactions between an array of people with often strongly divergent linguistic, cultural and political commitments.  相似文献

Nearby a somehow “official“ philosophy of technique, works have appeared in recent German literature where different techniques are studied according a renewed philosophical agenda about their concrete historical development. Once 19th Century German philosophy of technique briefly sketched, a sample from this recent production is considered. Surprisingly, they are meeting current literary studies and cultural history.  相似文献

The paper presents an extended summary of the most important earthquakes of the 19th century in the Marmara Sea region in north-west Turkey. We can find no evidence for a significant earthquake occuring during the first half of the 19th century, a period during which the west terminal of the North Anatolian fault system was much more active further west.This variation of activity with time of segments of fault zones, such as the Anatolian, is typical; the smaller the segment considered the longer the sampling period needed for moment rates and hazard estimates to be reliable. We find that the larger and some of the smaller events of the 19th century are clearly associated with known active faults which have generated earlier and later damaging earthquakes.  相似文献

Abstract

This paper will look at some of the excavated material for British urban workers’ housing, built and occupied during the period 1800 to 1950 in the Ancoats area of Manchester: Ancoats was notorious amongst contemporary writers and campaigners for its poor quality and overcrowded housing. This archaeological evidence has emerged as a result of developer-funded excavations and represents part of a growing body of data collected since 1990 from within many of the great industrial cities of Britain (Glasgow, London and Manchester), as well as excavations in the numerous smaller industrial manufacturing towns of the UK. In this study particular attention is given to the impact of national legislation, private acts and local by-laws aimed at improving industrialised living conditions and the build quality of 19th-century workers’ housing occupied into the 20th century. Using excavated examples from more than 50 houses within Ancoats, it will be argued that archaeology can provide a distinctive and unique view of urban domestic life in the 19th and first half of the 20th century, whilst demonstrating continuity in occupation patterns during this period. The evidence for urbanised, industrial living also compliments the more extensive archaeological studies of manufacturing industry from the period.  相似文献

Prominent environmental scholars and activists in India have posited that environmental crises in the Indian Himalayas result primarily from adopting forestry practices that override local communities and argue that the region can be sustained only when the state allows local communities to practice indigenous forest management. This paper challenges those critiques: focusing on the Garhwal Himalayas, it shows that forestry practices involve contestation and negotiation between the state and local communities and argues that environmental scholars fail to recognize how particular classes have shaped forest use and management practices and played a central role in determining environmental sustainability for local communities.  相似文献

Community‐based forestry management is emerging as an important component of forest policies in the developing world. Using the Philippines as a case‐study, this article critically examines the way in which community‐based forestry is constructed and understood among government policy makers. The author suggests that the new policy discourse of community‐based forestry policy in the Philippines is still shaped by efforts to maintain centralized control over forest management and a political economy orientated towards commercial timber production using the principles of ‘scientific management’. While timber production and the technical aspects of forest management are emphasized, social and environmental considerations remain neglected.  相似文献

Visualization in 19th‐century German geography: Robert Schlagintweit and Hans Meyer as examples. – Visual representations of nature formed an essential part of 19th‐century earth sciences. In particular, colonial photography – as a visual source, and as an instrument of the construction of national identities – serves essential research interests of current history and social sciences. The present paper is a case study on the role and function of photography in German geography of the 19th and early 20th centuries. It focuses on the work of the Munich geographer Robert Schlagintweit (1833–1885) and the Leipzig colonial geographer Hans Meyer (1858–1929); the early history of photography in India and the function of images in the geographical exploration of overseas territories are discussed. Although there is nearly half a century between the work of R. Schlagintweit and H. Meyer, their photography shows remarkable parallels. The ideas of both on the practice of visualization are rooted in pedagogic and didactic concepts as well as in popular science. For both geographers photography was essentially a technical help, which often needed graphic revisions. And they both preferred photography to depict people and buildings (compared, for instance, to landscapes). Concerning the more comprehensive question of how far their photography transmitted a specific German ‘image of abroad’, it is indicated that such a specific image should have its essential roots in a peculiar visual culture of German earth sciences in the first half of the 19th century. Thus the paper offers a starting point for further studies discussing the change from a ‘Biedermeier image’ of foreign cultures to a more ‘colonial’ one in 19th‐century German geography.  相似文献

As visibly extractive industries reliant on the material and semiotic commodification of nature, forestry and mining have come to be popularly viewed as "environmental pariahs." Yet forestry and mining continue to be successfully profitable enterprises despite a significant increase in environmental awareness and activism in the latter half of the twentieth century. To understand the relative stability and growth of these sectors in the face of overt contradictions arising from their use of the environment, this article revisits the work of regulation theorists who asked similar questions about the persistence and maintenance of capitalism in general.
Two case studies are presented–forestry in British Columbia and gold mining in California and Nevada–which demonstrate how the political economy of forestry and mining is subject to contradictions arising out of the technological and organizational mechanisms through which nature is appropriated during production. Analysis of the case studies shows that the regulation of these contradictions is increasingly achieved through the deployment and cooptation of sustainability narratives. The case studies therefore juxtapose the recent proliferation of sustainability narratives within the forestry and mining sectors with the sectors' persistent challenge to concepts of sustainable development.  相似文献

This paper evaluates the significance of the battle between forest and conservation interests in the Flow Country of northern Scotland during the late 1980s. It summarises the key arguments for and against afforestation as they were presented at the time, and reviews their validity in the light of subsequent developments. Commercial afforestation was claimed to be an economically valuable land use in a region with few alternatives, whereas conservationists presented the Flow Country as a wetland habitat of international significance. The controversy had far‐reaching consequences both for forest practice and nature conservation in Scotland and the UK. The break‐up of the Nature Conservancy Council and the remit given to Scottish Natural Heritage, the negative public perception of commercial forestry, the adoption of multiple objective forest management, Indicative Forest Strategies, and the participatory philosophy in conservation, can all be wholly or partly traced to the controversy. Ultimately, the controversy is shown to have had positive outcomes both for conservation and forest practice.  相似文献
