围绕自然资源与经济发展相互关系这一主题,选取浙江省安吉县小流域为研究区域,探讨了山区小流域可更新资源与经济发展之间的空间耦合关系。参照高程变化,以每100m高程间隔为单元,以安吉县相关统计资料和实地调查资料为基础数据,计算各高程段各类可更新资源的GDP产出,进而计算实现经济转化的资源价值量TRV,再计算TRV占资源价值的比例、TRV占GDP的比例。研究表明,随地势升高,各高程段总体TRV与资源价值的比值降低,说明可更新资源的开发程度越来越低;总体TRV与GDP的比值呈增加趋势,经济发展对本土资源的依赖性增加。整个小流域经济产出利用了本土可更新资源总价值的15%,本土可更新资源实现经济转化的那部分资源价值贡献了GDP总量的12%。  相似文献

Stakeholder participation is considered a key principle for sustainable development in the context of natural resource and disaster risk management. Participatory modelling (PM) is an interactive and iterative process in which stakeholder involvement is supported by modelling and communication tools. Planning and decision-making for sustainable development (SD)integrate three substantive dimensions − social, ecological and economic. The procedural dimension of SD, however, is equally important, and here we see great potential for PM. In this study, we evaluate five PM research projects against criteria for the procedural dimension of SD. This provides a basis for identifying key issues and needs for further research into PM for SD. While the cases show great potential, especially for supporting knowledge integration, learning and transparent handling of values and perspectives, they indicate a particular need to develop PM in respect of organizational integration. This issue is closely connected to the possibility of effectively implementing PM in practice.  相似文献

Industrial ecology (IE) is an emerging framework adopted in the manufacturing, construction, and process industries to provide innovative solutions in strategic planning, leading to cleaner operation and production. An IE framework integrates a large number of processes, economic constraints, and environmental, health and safety considerations for optimized resource utilization. This paper provides a review of environmental management practices in the mining and minerals industry, emphasizing two concepts: IE and cleaner production. The mining and minerals industry provides primary materials for industrial activities; as such, it is an important component in the “industrial ecosystem.” This industry is subject to very stringent social and environmental scrutiny, while providing society with required natural resources to meet essential sustainable development requirements. The implementation of an IE framework in the sector will contribute to sustainable development.  相似文献

The mountain chain of the Sierra Madre de Chiapas in southern Mexico is globally significant for its biodiversity and is one of the most important coffee production areas of Mexico. It provides water for several municipalities and its biosphere reserves are important tourist attractions. Much of the forest cover outside the core protected areas is in fact coffee grown under traditional forest shade. Unless this (agro)forest cover can be sustained, the biodiversity of the Sierra Madre and the environmental services it provides are at risk. We analyzed the threats to livelihoods and environment from climate change through crop suitability modeling based on downscaled climate scenarios for the period 2040 to 2069 (referred to as 2050s) and developed adaptation options through an expert workshop. Significant areas of forest and occasionally coffee are destroyed every year by wildfires, and this problem is bound to increase in a hotter and drier future climate. Widespread landslides and inundations, including on coffee farms, have recently been caused by hurricanes whose intensity is predicted to increase. A hotter climate with more irregular rainfall will be less favorable to the production of quality coffee and lower profitability may compel farmers to abandon shade coffee and expand other land uses of less biodiversity value, probably at the expense of forest. A comprehensive strategy to sustain the biodiversity, ecosystem services and livelihoods of the Sierra Madre in the face of climate change should include the promotion of biodiversity friendly coffee growing and processing practices including complex shade which can offer some hurricane protection and product diversification; payments for forest conservation and restoration from existing government programs complemented by private initiatives; diversification of income sources to mitigate risks associated with unstable environmental conditions and coffee markets; integrated fire management; development of markets that reward sustainable land use practices and forest conservation; crop insurance programs that are accessible to smallholders; and the strengthening of local capacity for adaptive resource management.  相似文献

应对全球化变革及其不确定性,认识中国对外自然资源流动的特征与问题,是保障国家资源安全的基础,对实现高质量、可持续发展有重要意义。对应国际劳动分工从产业间贸易、产业内贸易到全球价值链的不同阶段,理解中国对外自然资源流动有不同的理论视角。现有研究主要关注自然资源以原始形态和制成品中的隐含形态在国家之间的流动,讨论了中国对外自然资源流动在供给与需求、利用强度与效率、资源禀赋与流向,以及全局与局部影响之间的矛盾。未来研究仍面临理论和现实的挑战。在理论方面,适应全球价值链分工发展,引入全球生产网络理论探讨企业间互动关系如何塑造自然资源流动路径,能更好地适应中国从“引进来”向“走出去”的转变,以及当下自然资源综合治理的研究需求。在现实方面,应对日益增强的不确定性,亟需深化对自然资源流动网络韧性,以及“双循环”互促关系的认识。  相似文献

跨国世界自然遗产保护现状评述   总被引:1,自引:0,他引:1  
陆小璇 《自然资源学报》2014,29(11):1978-1989
国家疆界的划分原则常常与自然资源及生态功能区划分的原则相悖;动植物种群分布、生态学过程以及地质构造分布,并不因政治边界的存在而消失。这种情况为一些自然遗产地的统一与完整性保护制造了障碍。在过去的几十年中,人们对自然资源管理以及对生物多样性管理的关注点,由原来对特定区域的保护转向强调景观尺度下生态系统连续性的保护。连续性保护理念在跨国项目中体现为跨界保护理念,使连接分散的生态区域之间的动态过程成为可能。跨国世界自然遗产的建立与保护已成为推进跨界资源保护的重要一环。结合相关案例分析,论文从发展历程、分类以及管理三个方面对跨国世界自然遗产保护现状进行评述。资源的不可持续利用目前被认为是对世界遗产保护的最大威胁。跨国自然遗产将通过促进多边合作,在遗产保护与可持续发展之间建立平衡。  相似文献

This article draws lessons from a seven-year project on conservation and use of remaining coffee forests in the highlands of South-west Ethiopia. The project investigated the genetic diversity of Coffea arabica in its place of origin as well as economic perspectives of quality coffee marketing. With initially broad multidisciplinary natural and social sciences research a basis was laid for a second phase of praxis and implementation-oriented research in the same region.As a key innovative approach an NGO was established to take over all project management and implementation-oriented work in Ethiopia at the beginning of the second phase. This initiative helped decisively to solve the kind of problems identified in RESCUE (2012): ownership of results developed within R&D, the often missing mandate for science to actively contribute to solutions ‘on the ground’, and problems of cultural and social unsuitability and misunderstanding, which often are at the core of the problem when solutions from scientists are expected.The NGO operated as an intermediary between the involved scientists and other stakeholders from the coffee industry as well as from public administration and the Ethiopian polity. Its overall target was to contribute toward establishment of a biosphere reserve following the UNESCO MAB scheme and to use this scheme for the conservation and use of the remaining Ethiopian coffee forests. This target was achieved: the biosphere reserve has been accepted and accredited by UNESCO and is in operation. In addition, quality coffee from the development zones of the biosphere reserve is being sold on local markets in Yayu, SW Ethiopia.There are important lessons for the future of transdisciplinary and transformative sustainability science that can be drawn from this experience. These lessons concern concrete challenges and chances of research and development geared toward sustainable development:
  • •Working with implementation-targets as project organizing elements,
  • •communication and transfer of responsibility to involved stakeholders,
  • •challenges for praxis-oriented syntheses from research results,
  • •practical challenges of management and coordination for transdisciplinary projects, as well as.
  • •chances for long-term sustainability and use of research and implementation work.
These lessons are described in this article with the overall intention to draw conclusions and to make them more widely available for scientists and project coordinators working in transdisciplinary projects that aim to contribute toward (more) sustainable development.  相似文献

In West Africa, rural livelihoods depending on natural resources develop coping and adapting strategies to face climate variability or change and economic or political changes. The former Lake Faguibine in northern Mali has experienced drastic ecological, social, and economic changes. Forests have emerged on the former lake and have become important for local livelihoods. This paper analyses the coping and adapting strategies of forest- and livestock-based livelihoods facing ecological changes. Results from field research at different levels indicate that most local strategies are based on diversification including migration within the livestock production system or in complement to it, with differences according to gender, age, and ethnicity. Political discourses, cultural identities, and past experiences influence and shape adaptation strategies at the local level. The sustainability of the observed strategies depends on the access to natural resources and the sustainable management of these resources, which in turn depends on institutions at local and national levels. Many local strategies are reactive to external events but would need strategic support from higher levels to move from coping to adapting. Examples are the development of institutions and technical actions for natural resource management, as well as development actions supporting local strategies and sustainable investments. Researchers, practitioners and development planners will need simple methods and tools for understanding and analysing local adaptation perceptions and actions to achieve an effective support of sustainable and gender-equitable local adaptation and to avoid mismatches between strategies proposed by local and by sub national and national actors.  相似文献
