The paper presents a novel transdisciplinary approach to investigate non-sustainable civilisation–nature interactions in the context of global change. The approach rests on the decomposition of intricate dynamics of Global Change into problematic patterns civilisation nature interactions (‘syndromes’) this is done by an iterative process of observations, data and theoretical system analysis and GIS-based modelling attempts. These syndromes of global change characterise endangering and risky developments of civilisation nature interaction and represent a baseline for measuring and indicating ‘non-sustainability’; in order to have a sustainable development it is necessary to have a far-reaching absence of syndromes. They encompass the core problems of global change, e.g. soil degradation, climate change, threats to biodiversity or global deforestation. Patterns are defined as characteristic constellations of global change trends (‘symptoms’). Cause–effect schemes of symptoms and their interrelations are constituted as complex phenomena resulting from interactions over the different spheres of the Earth system (biosphere, atmosphere, hydrosphere, population, pedosphere, economy, psychosocial sphere, social organisation, science and technology). The approach is illustrated by an analysis of civilisation–nature interaction patterns relevant for global deforestation. Global forest ecosystems have been chosen for this investigation because of their important role in the global carbon cycle and their importance for biological diversity. The resulting geographical patchwork of the combined dispositions and intensities of the different syndromes describes current and future regional threats to forests by their underlying global cause–effect patterns of civilisation–nature interaction. 相似文献

Since establishment of the ISO 14001 environmental management system in 1996, Japanese facilities have led the world in numbers of certifications. This research utilises survey data from more than 1700 Japanese facilities as well as follow-up interviews to identify the determinants of ISO certification, to examine the differences between early, recent and in-process certifiers, and to understand how ISO 14001 certification affects various environmental and managerial outcomes in Japan. Findings show that ISO certified facilities are larger and report higher levels of environmental management capacity. In addition, early certifiers are more likely to have established voluntary environmental agreements and are more active in international trade and business. Findings also provide evidence that while many facilities believe that ISO 14001 certification is excessively costly, they also report that certification has resulted in the establishment of new energy efficiency and waste reduction targets and higher target levels. Nevertheless, evidence indicates that certification does not generally result in longer-term outcomes such as post-certification adjustment of non-regulated targets. 相似文献

Currently one of the largest and most rapidly developing countries, China also has some of the world's most severe environmental problems. China will most likely need to use all of the potential major strategies currently available to solve the country's huge environmental challenges, including promoting individual conservation behavior through educational campaigns and encouraging public environmental advocacy. This paper summarized the findings of a survey of 347 residents of Shaanxi province on environmental attitudes and behaviors. The survey found generally high levels of environmental knowledge and high recognition of the seriousness of environmental issues, moderate levels of individual actions supporting environmental resource conservation and low levels of public environmental behaviors, particularly for organized public advocacy. Further analysis indicated that the perceived importance of environmental protection is the most important factor influencing individual environmental resource conservation, but not public advocacy behaviors. Implications for environmental campaigns are discussed. 相似文献

Many organizations in environmental fields stand to benefit from the use of a geographic information system (GIS). Selecting
a GIS to implement within an organization can be a difficult task that is often required of people with little experience
using a GIS. A framework for evaluating competing GIS considers cost, functionality, ease of use, future stability, development
potential, support availability, and maintenance costs. Initial cost involves more than the actual purchase price of hardware
and software; it includes the cost of building the data base and training users within the organization. Functionality refers
to the depth and breadth of capabilities of a GIS. Issues involved in evaluating functionality include the appropriateness
of raster vs vector processing and the ability to add your own software. Ease of use is important, but there is generally
a trade-off with functionality. The degree of centralization of use of the GIS within the organization affects requirements
for ease of use. GIS are rapidly evolving, and as a result it is important to select a system with high potential for future
development. With the proliferation of companies offering GIS it is important to select one that is likely to survive and
prosper. Similarly, the ability to find support in the forms of technical help, advice, and possibly even skilled employees
can be significant. 相似文献

Mapping wetlands in the Lower Mekong Basin for wetland resource and conservation management using Landsat ETM images and field survey data 总被引:1,自引:0,他引:1
The Mekong River Basin is considered to be the second most species rich river basin in the world. The 795,000 km(2) catchment encompasses several ecoregions, incorporating biodiverse and productive wetland systems. Eighty percent of the rapidly expanding population of the Lower Mekong Basin (LMB), made up in part by Lao PDR, Thailand, Cambodia and Viet Nam, live in rural areas and are heavily reliant on wetland resources. As the populations of Cambodia and Lao PDR will double in the next 20 years, pressure on natural resources and particularly wetlands can only increase. For development planning, resource and conservation management to incorporate wetland issues, information on the distribution and character of Mekong wetlands is essential. The existing but outdated wetland maps were compiled from secondary landuse-landcover data, have limited coverage, poor thematic accuracy and no meta-data. Therefore the Mekong River Commission (MRC) undertook to produce new wetland coverage for the LMB. As resources, funding and regional capacity are limited, it was determined that the method applied should use existing facilities, be easily adaptable, and replicable locally. For the product to be useful it must be accepted by local governments and decision makers. The results must be of acceptable accuracy (>75%) and the methodology should be relatively understandable to non-experts. In the first stage of this exercise, field survey was conducted at five pilot sites covering a range of typical wetland habitats (MRC wetland classification) to supply data for a supervised classification of Landsat ETM images from the existing MRC archive. Images were analysed using ERDAS IMAGINE and applying Maximum Likelihood Classification. Field data were reserved to apply formal accuracy assessment to the final wetland habitat maps, with resulting accuracy ranging from 77 to 94%. The maps produced are now in use at a Provincial and National level in three countries for resource and conservation planning and management applications, including designation of a Ramsar wetland site of international importance. 相似文献

In principle the protection of environmental resources is in every ones interest, yet it is evident that this is not what often occurs. In some cases there is an identifiable person or corporation, whose environmental impact can be tractably regulated either politically or via market forces. In other cases there is cumulative impact on a commonly held or "common pool" resource, from a variety of users, making establishing rights and responsibilities for resource management more difficult. The water of the Ythan catchment is one such 'Common Pool Resource' (CPR). An intensively farmed catchment also sustaining a sizable population, the consequent nitrate inputs to the water are believed to be the cause of algal matting at the estuary mouth, an internationally designated wildlife reserve. This led to its designation as Scotland's first Nitrate Vulnerable Zone (NVZ). Supported by the EU Life Environment fund, the Ythan Project attempted to foster co-operation between farmers and the wider community of the Ythan catchment to protect and restore the river environment. Throughout the project surveys were undertaken concerning the popularity of the Ythan Project's voluntary approach compared with more individualist or state-organised approaches. Taking CPR theory as a framework, key findings from those surveys are presented and discussed as to their implications for organisational intervention in CPR problems. 相似文献

Mineral exploitation is a necessary component of China's economic development goals. Such exploitation brings with it the potential for serious environmental degradation. Careful environmental impact assessments of mining projects are required in order to implement China's environmental protection law and identify measures for protecting surrounding agricultural environments. This article describes an environmental information system that has been developed for the purpose of assisting with the environmental impact assessment of nonferrous mining operations with a particular focus on agricultural impacts. An application of the environmental information system to the Yongping copper mine, located in Jiangxi Province, is discussed. The role of the environmental information system is analyzing and predicting soil contamination from heavy metals and other types of impacts from this mining operation is described. The environmental information system is designed for implementation on an IBM PC/XT microcomputer. The experience gained from the Yongping copper mine application and the growing popularity of microcomputers in China indicate a significant potential for the effective use of a microcomputer-based environmental information system in other parts of China. 相似文献

A binary response estimation procedure using contingent valuation data is proposed for estimating the incremental environmental benefits associated with the use of constructed wetlands to control agricultural waste-water runoff. The model uses two binary responses per individual while circumventing the non-independence problems associated with follow-up valuation questions. Case study results suggest that the methodology provides a potentially effective means for measuring the non-market benefits of constructed wetlands in addition to water-quality maintenance.1998 Academic Press 相似文献

With the entry into force of the Protocol on Environmental Protection to the Antarctic Treaty (the Protocol) in January 1998, key operational aspects of the newly established Committee for Environmental Protection (CEP), such as its advisory capacity to Antarctic Treaty Consultative Meetings (ATCMs) need to be urgently addressed. This paper advocates the use of a geographic information system (GIS) environmental database to reinforce the advisory capacity of the CEP. The demonstrated links between the provisions of the Protocol and GIS capabilities illustrate the potential this has to assist the CEP in delivering informed advice to ATCMs. The range of GIS applications that could be utilized by the CEP in fulfilling its functions are examined by reference to precedents in Europe (CORINE) and Australia (ARIS). 相似文献
