In recent decades the international wood chip industry has been the major cause of indigenous forest destruction in New Zealand. This paper analyses how changing state forest policies have affected wood chipping of indigenous forest. Emphasis is placed on wood chipping on private land through a case study of the reactions and changing attitudes of farmers. It is argued that farmers and Maori landowners often have no other alternative but to allow wood chipping on their land. Although government policies have been tightened in recent years, and although attitudes among private landholders are shifting towards forest conservation, the pressure on New Zealand's lowland indigenous forest remnants continues unabated.  相似文献

In Australia, the Commonwealth and State governments are increasingly devolving natural resource management (NRM) responsibilities to regional bodies. This move has led to the development of regional NRM plans. Native vegetation and biodiversity conservation, along with soil, pasture and water resources, are key components of the regional NRM plans in Queensland's extensive rangelands. This paper outlines and applies a set of criteria for evaluating the native vegetation and biodiversity content of accredited regional NRM plans for Queensland's rangelands. The evaluation showed considerable variation in the comprehensiveness of the information and knowledge base and management action targets among plans, including the poor articulation of impacts of excessive grazing pressure on biodiversity. The NRM plans lacked effective integration of natural resource, native vegetation and biodiversity conservation targets and actions. Several regions had too many biodiversity targets, many of which were poorly integrated. This is symptomatic of a limited understanding of rangelands as ecological systems and the lack of an integrated planning framework. We conclude regional NRM planning is not a ‘silver bullet’ for biodiversity conservation in the rangelands, but rather, it is the beginning of a long road to address complex, multi‐scale problems at a regional level.  相似文献

Our impressions of Canadian resource-dependent communities are often still influenced by the classic works of Innis, Robinson, Lucas, Siemens, and others. Although this research has proven to be valuable, it has also established several generalizations regarding these settings, including the perceptions that community labour forces and economic structures are relatively homogenous, that nonresource sectors play an insignificant role in the communities, and that these communities are found primarily in isolated northern regions. These generalizations are now beginning to be questioned, given the rapid economic and social changes taking place in these communities and the recent theoretical and empirical contributions of geographers and other social scientists. This paper summarizes this classic research, then challenges these generalizations by discussing recent applications of the concepts of economic restructuring and labour-market segmentation theory to the context of resource-dependent communities. To further illustrate these characteristics, the paper then presents an empirical analysis of 220 Canadian resource-dependent communities across six resource sectors, focusing specifically on their labour-market characteristics and the relationship between resource dependence and spatial isolation. Nos impressions des communautés mono-industrielles canadiennes spécialisées dans la production des ressources sont souvent encore influencées, entre autres, par les études classiques de Innis, Robinson, Lucas, et Siemens. Bien que cette recherche ait prouvé sa valeur, elle a aussi servi àétablir plusieurs généralisations concernant ces milieux, incluant les notions que la main d'oeuvre et les structures économiques de ces communautés sont relativement homogènes, que les secteurs non-reliés à l'exploration des ressources n'y jouent qu'un rôle peu significatif, et que ces communautés se retrouventsurtout dans les régions isolées du nord. Ces généralisations sont maintenant soumises à une remise en question, compte tenu des changements économiques et sociaux rapides dont ces communautés font l'objet et des récentes contributions théoriques et empiriques de géographes et d'autres chercheurs en sciences sociales. Cet article résume cette recherche classique et conteste ces généralisations en commentant les récentes applications du concept de restructuration économique etde la théorie de la segmentation du marché d'emploi associés au contexte des communautés dépendentes de l'extraction de ressources. Afin d'illustrer ces caractéristiques, l'article présente une analyse empirique portant sur 220 communautés canadiennes et sur six secteurs de ressources, etse concentre plus spécifiquement sur les caractéristiques de leur marché de la main-d'oeuvre et sur les liens existant entre la condition de dépendance à une ressource et l'isolation spatiale.  相似文献

This study analyses the background to the rise of Chile as a major wood chip exporter, and assesses the environmental impact and relative economic importance of the Chilean wood chip industry. Chile is acting as a ‘surrogate’ for lost Australian hardwood chip exports to Japan. Compared to other countries, the wood chip industry in Chile has had a disproportionate impact on its remnant native forests and is essentially predicated on unsustainable forest management practices. Despite this, the relative economic importance of Chile's export wood chip industry is low when compared to value-added forest product export industries such as chemical pulp.  相似文献

Excavations at 150 Stratford High Street, London E15, found evidence for Saynes Mill, a tide powered grain mill of medieval origin, converted in 1745–62 into a pumping station for the West Ham Water Company with an engine installed by John Smeaton. The large-scale reconstruction meant that there was limited survival of earlier buildings, but many later structures survived almost intact and stretches of the quays that flanked the Waterworks River were also recorded. The excavated remains of both the buildings and revetments spanned the period from the late 15th to the late 19th centuries.  相似文献
