A first fossil record for Scolytus scolytus (F.) (elm bark beetle): its occurrence in elm decline deposits from London and the implications for neolithic elm disease

A problem which has arisen in discussions of an elm-disease explanation for the Neolithic elm decline has been the lack of fossil records of Scolytus scolytus (F.) (elm bark beetle), which is the main carrier of the fungus which causes the present epidemic of Dutch Elm Disease. Now, the discovery of wing cases of two individuals from elm decline deposits at Hampstead Heath, London, proves that the beetle was present in Britain during this episode. The deposits in which it occurs are described, and the various implications for elm disease causing, aiding or at least occurring during this stage of the early Neolithic are discussed.     

中英国家公园旅游可持续性比较研究——以中国九寨沟和英国新森林国家公园为例

中英两国国情迥异,但两国的国家公园均以自然保护、旅游与社区可持续发展为管理目标。本文以中国九寨沟和英国新森林国家公园为例,构建了由12个客观指标和12个主观指标组成的国家公园旅游可持续性评价指标体系,通过专家咨询和均方差法计算指标权值,用加权指标综合评价方法对案例地旅游可持续性进行了评价。评价结果表明,九寨沟旅游发展具有潜在的可持续性;而新森林国家公园则具有潜在的不可持续性。论文最后从两国国家公园管理体制和模式差异对评价结果进行了解释。     

Trees as technology: planting shelterbelts on the Great Plains

The turbulent climate of the Great Plains made windbreaks necessary for the protection of settlers and their livestock and crops. At first individual farmers tried to plant their own shelterbelts but with little success. The US Forest Service, with the establishment of the Bessey tree nursery, in 1902, and the field planting of the Nebraska National Forest, developed the expertise to carry out farm forestry on the plains. In 1934 the Forest Service undertook the Prairie States Forestry Project, an eight‐year program to plant shelterbelts from Canada to Texas, in response to the Dust Bowl and the Great Depression. These shelterbelts were a technological solution to environmental and social problems. As they grew, successful shelterbelts developed forest characteristics and served as habitat for birds and wildlife. As systems that were both technical and ecological, shelterbelts embodied a confluence of culture and nature in the technology that farmers and foresters used to engineer a more suitable environment for American society on the Plains.

Sustainable management of metallurgical forest on Mont Lozère (France) during the Early Middle Ages

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.     

中国森林面积缩减与生态环境的恶化

中国是一个森林资源比较贫乏的国家。更值得忧虑的是,几十年来,原本就十分贫乏的森林资源却遭到大规模的不合理的毁伐,面积缩减了24％。森林资源缩减,使生态环境严重恶化:旱涝灾害增加,土壤侵蚀严重,土地草原沙漠化,空气污染加剧,许多生物种类濒临灭绝。本文以大量数字和事实,尖锐而坦率地指出了我国人民面临的严峻问题,并提出了解决这一问题的方略。     

Deliberative democracy and the Tasmanian forest peace process

Decades of contention regarding Tasmania's forests have been accompanied by several attempts for peace. Most recently the ‘forest peace process’ culminated in the 2012 Tasmanian Forest Agreement (TFA). We evaluate the peace process that led to the TFA, and its subsequent dismantling, from the perspective of deliberative democracy, which promises to achieve democratically legitimate outcomes in the toughest conflicts. Using normative criteria to evaluate the deliberative democratic quality of the process, our analysis shows that trades-offs were needed, and not all normative criteria could be achieved equally and simultaneously. Despite its shortcomings, and short-lived life, the peace process illustrates the possibility of achieving meta-consensus in deep value conflicts, and the crucial role of this consensus for sustaining deliberation.     

Inventing the “Pygmy”: Representing the “Other”, Presenting the “Self”

In this article, I investigate historical representations of Central African Forest People that have been constructed by explorers, scientists, colonial officers, journalists and the European public in order to provide a historical analysis of the concept of the “Pygmy”. Following Said’s argument regarding Orientalism, that “without examining Orientalism as a discourse one cannot possibly understand the enormous systematic discipline by which European culture was able to manage—and even produce—the Orient politically, sociologically, militarily, ideologically, scientifically, and imaginatively” (1995 Said, E. W. 1995. Orientalism, Harmondsworth, , UK: Penguin.  [Google Scholar]: 3), I will draw on representations of Forest People from written accounts of the last 200 years. None of these accounts should be regarded as representative of Forest Peoples’ own representations of themselves, so what I hope to provide is a clear picture of how Forest People have been represented by others through the discourses of race, evolution and colonialism.     

What a difference a skidder makes: The role of technology in the origins of the industrialization of tree harvesting systems

We examine in this paper the concurrent appearance of the first two woods machines--the skidder and forwarder. By replacing the horse they initiated the industrial revolution in tree harvesting. We describe their invention and technological development. We then assess their diffusion in the woods, revealing the greater success of the skidder. We demonstrate that this cannot be accounted for solely in terms of their respective technologies. Instead, we argue that the interaction of technology with the social organization of their respective harvesting systems must be analyzed. By doing so, we find that the skidder altered that social organization whereas the forwarder did not. This paper, contributing to the understanding of an important area of economic activity which has been seriously understudied, illustrates concretely that comprehending technology requires locating it in the social organization of work.     

Letting Indigenous People Talk About Their Country: a Case Study of Cross‐Cultural (Mis)communication in an Environmental Management Planning Process

This paper presents a case study, based on the experiences of two senior Aboriginal traditional owners who were engaged in negotiations surrounding the establishment of a Regional Forest Agreement (RFA) in southeast Queensland. This case is notable as an illustration of the capacity of natural resource management planning, through negotiation within a formal process, to extinguish native title. Importantly, the personal experiences of two senior Aboriginal people provide an insight into a situation designed to enhance interactions between government and community, with the overt intention of improving natural resource management. However, the record of this personal experience indicates that the communication was less than satisfactory and that the outcomes, at least in terms of the experiences recorded here, of the individual senior Aboriginal community members, was less than satisfactory. We conclude that, despite best intentions, there is an important lack of provision for community influence or power, including any legal or administrative institutional framework. We also conclude that there are important institutional and social processes of engagement still to be developed, including ways of engaging the community more widely that has conventionally been the case.
