Variety in cereal cultivation in the Late Bronze and Early Iron Ages in relation to environmental conditions

The objective of this paper is to assess the relationship between the cereals cultivated in the Late Bronze and Early Iron Ages (ca. 1250–400 BC) within the area of the present-day Czech Republic, and their environmental settings. The various charred caryopses of cereal species represented in the archaeobotanical assemblages from 35 archaeological sites differ, especially in the proportion of wheat and barley. The cereal assemblages were compared regarding site altitude, weather conditions, soils and soil productivity. The most important environmental variable influencing the choice of a particular crop seemed to be altitude which is correlated with other variables such as the length of growing season, mean annual temperature, soil quality etc. Although the ecological requirements of cereals cultivated in the Late Bronze and Early Iron Ages are not known, they presumably thrived under similar conditions to present-day species/varieties, and the strategy of past crop husbandry was based on similar principles as today, e.g. flexible adaptation to local environmental conditions, in an effort to achieve optimal yields and reduce the danger of crop failure.     

The Conservation of English Cultural Built Heritage: A Force for Social Inclusion?

Debates about the socially inclusionary potential of heritage have to date focused principally on heritage sites and museums. Relatively little attention has been paid to the wider Cultural Built Heritage (CBH) that surrounds us in our everyday lives. This paper starts with a brief theoretical exploration of the social role of heritage and the key policy background. Then, based on an understanding of policy and action in England, this paper sets out a framework for considering how this wider CBH might contribute to social inclusion. A fundamental binary divide is made between the role of CBH as historic places and opportunity spaces in which regeneration may occur. However, in neither case is action necessarily socially inclusive. The paper concludes that a greater clarity of objectives and definitions is necessary if CBH is to meet its potential to be socially inclusionary.     

Architects Creating a Landscape

This article is derived from a research project designed to establish a better understanding of the nature of professional architectural activity in the State of Victoria, Australia, in the second half of the 19th century. It posed the following question: why is the activity in rural areas not acknowledged by the traditional approaches to studying architectural history? Part of the conclusion is that our understanding of urban cultural landscapes/townscapes will be improved if we look beyond the limitations of separate disciplines such as architectural and social history or historical geography. The landscape is built from many layers and they all need to be acknowledged if we are to understand what we find important about it. The reasons for seeking the conservation of our urban environment cannot be related solely to the peculiar interests of one discipline alone. Over the past 30 years the Australian community has developed a substantial interest and appetite for heritage conservation and along with that has grown a broadening interest in how the importance of the urban environment is defined.     

Viewing Urban Development from the Evolution of the Social Environment

Although place-marketing and image-enhancement are increasingly common elements of Western urban policy, when applied to specific locales, these abstract theories have to negotiate local conditions and contexts. This paper discusses the ways attempts to place-market the city of Hull, England, prompted debates surrounding questions of place, memory and heritage. Despite being Britain's leading fishing port in the 20th century, Hull's place-marketing strategy elided this past in favour of a sanitised vision of a modern, post-industrial city. These debates crystallised around a 1999 planning inquiry over the proposed redevelopment of the erstwhile fishing dock. While the proposals contained some reference to the dock's role as a site of place-memory, this was deemed insufficient by local protest groups and politicians who argued for a more appropriate memorial to Hull's fishing community. Eventually, the redevelopment proposals were accepted, but not before attendant debates exposed both the depth of local sentiments over place-memories and fishing heritage, and also the difficulties of negotiating inclusive and plural heritage landscapes.     

从《气候变化框架公约》进展看当前国际环境关系

自1992年联合国环境与发展大会缔结了为气候变化问题上的全球合作提供法律框架的《气候变化框架公约》以来,国际上已经历六次缔约方大会。虽然1997年其第三次缔约方会议签订了具有削减温室气体排放数量和时间限制具体目标的《京都议定书》,取得了该领域的一个关键性进展,但最近在荷兰海牙召开的旨在就《京都协定书》的目标与措施达成具体协议的第六次缔约方会议却以失败而告终。纵观国际社会在《气候变化框架公约》问题上的后续行动进展,可以充分看出当前的国际环境关系具有环境问题政治化、环境关系复杂化、环境合作艰难化以及环境斗争激烈化的特点。这使中国今后在环境与发展的问题上将面临更加严峻的挑战,为此必须尽早采取有效对策。     

Landscapes without the car: a counterfactual historical geography of twentieth-century Britain

Despite increased concern about environmental damage and resource depletion, the private motor car, and associated automobility, are taken-for-granted aspects of twenty-first-century life. This paper makes the counterfactual assumption that private ownership of cars was severely restricted at the start of the twentieth century, and uses a range of historical data to examine the ways in which such a scenario might have impacted on transport infrastructure, personal mobility and urban life. It is argued that, even without the wholesale adoption of the motor car as a means of personal transport, patterns of everyday mobility would not have differed significantly from today so long as other forms of transport had remained or expanded to cope with this demand. However, such a scenario would probably have required journeys to be planned in different ways, may have been qualitatively different from travel today, and could have disadvantaged particular groups of the population, including some women. A landscape without cars would probably also have altered the form of cities, with services provided closer to where people live, and levels of air pollution substantially lower. The counterfactual historical analysis is used to argue that, although there is little likelihood of cars being banned in Britain, greater restrictions on private motor vehicles would not necessarily lead to the fundamental changes in everyday mobility that some might predict.     

The archaeology of industry; people and places

The development of industrial archaeology over the last 50 years can be traced through articles published in PMA. The early stages of recording the standing remains of industrial activity were augmented by detailed studies of groups of structures which revealed the organization of the manufacturing process. From the late 1980s, developer-funded excavations became important following extensive remediation work on brownfield sites. Greater attention was paid to the social context of past industrial activity including workers’ housing and institutional buildings, and this has continued with studies of oral history. New challenges considered include studies of modern technologies, de-industrialization and the digital revolution.     

Appraisal of Conservation Area Character in England: progress and problems

As the number of conservation areas within England continues to rise, it is increasingly important that adequate care and attention be given to their management. If not, the concept will be devalued and initiatives to protect and enhance such areas will not receive sufficient consideration. Conservation Area character appraisals have recently been suggested as a basis for the management of activities within Conservation Areas. This article considers the nature of advice on appraisals, and then the progress of English authorities in undertaking them. It will conclude with a number of issues and concerns which must be tackled if the potential of theses management instruments is to be fully realised.     

Developments in flood maps for flood risk management in Scotland

ABSTRACT

Sustainable flood risk management in Scotland is underpinned by the Flood Risk Management (Scotland) Act 2009. Effective delivery of actions to reduce the adverse impact of flooding are dependent on a collaborative approach by Responsible Authorities and a common understanding of flood hazard and risk. Over the last few decades, flood hazard maps have established a prominent role as essential tools in supporting effective flood risk management. They have developed as a result of improved national datasets and advances in computer processing. Improvements in modelling confidence and in the spatial representation of hazard and risk-inform confident actions set out in Flood Risk Management Strategies that coordinate actions supporting adaptation to future hazard conditions. The continued development of the accurate spatial representation of flood hazard and risk is an essential component of enhancing resilience in the face of future climate change.
