In an effort to control escalating fishing effort, a quota management system (QMS) of individual transferable quotas (ITQs) has recently been introduced in the Tasmanian rock lobster fishery. We outline and compare the input controls system in place before the introduction of a QMS, and we discuss the operation of the QMS to the end of its first full season in February 1999. We find cautiously for a successful introduction of a QMS as catch, effort and catch rate data tend towards what fishery managers believe to be bio economically sustainable levels.  相似文献

In Malawi, fishing community user groups known as beach village committees, traditional chiefs, government officers, and fishers are the key players in fisheries management. Fish catch trends at the Elephant Marsh Fishery in southern Malawi are declining. Based on interviews and participant observation, this article uses an actor-based framework (known as Action-in-Context) to unveil the issues that are crucial in devising a sustainable governance system for the fishery. We establish and propose that the key social variables for the design of a three-pillared (locally based, weak, and amorphous) resilient institution for sustainability of the Elephant Marsh Fishery are (i) the social reputation of the leaders of local fishery institutions (beach village committee leaders), and (ii) the power dynamics between traditional chiefs and these local fishery leaders. We end the article by exploring the implications of the findings on the sustainability of the fishery under rising resource pressure.  相似文献

南海渔业开发为维护我国渔业利益和海洋权益发挥了重大作用,近年来急速衰退的渔业资源和不断升温的冲突态势亟须寻找治理革新的突破口。基于此,首先从南海渔业资源环境特点、南海渔业资源开发利用历史沿革与现状,辨析南海渔业时空格局,指出南海渔业资源环境具有跨越国家界线的互通性、整体性与相互依赖性,且周边国家和地区对南海渔业高度依赖,并已经造成资源环境严重衰退。其次通过对南海渔业冲突和南海渔业资源治理所面临的挑战的梳理,指出引发南海渔业冲突的条件今后很可能更加普遍,亟需南海各方共同面对渔业可持续性危机,而南海地区面临的渔业资源环境退化、系统认知不足、区域协作有限等共性挑战与利益诉求,可成为促进区域合作的纽带。最后以区域渔业资源治理为抓手,提出了构建南海命运共同体的建设思路:从推动绿色水产养殖、增强资源环境修复、深化科研共享等方面开展务实的渔业资源治理合作;在区域、国家、地方层面完善跨尺度的海洋治理措施落实体系,协同提升国家层面的顶层涉海涉渔政策设计,强化地方、私营部门和公民个人在南海区域共建中的作用;从建立健全区域组织和完善区域海洋法制推动构建区域层面合作治理体系。  相似文献

New Zealand's policy goal to preserve coastal natural character was first incorporated into planning legislation in 1973 and protected area legislation in 1977. An evaluation of 100 relevant Resource Management Act Court decisions determined the Courts' interpretations of this policy goal. The Courts have repeatedly found that natural character is of nature (not culture), including natural elements, patterns, and processes. There is a continuum of naturalness from pristine indigenous ecosystems to the urban environment. A 2014 Supreme Court decision has upheld the use of environmental bottom lines for natural character and the importance of protection as part of sustainable management.  相似文献

For over 30 years, IHP (International Hydrological Programme) has been actively operating as a UNESCO’s (United Nations Educational, Scientific and Cultural Organization) international scientific cooperative programme in water research, water resources management, education and capacity-building, and the only broadly-based science programme of the UN (United Nations) system in this region. By a number of initiatives and networks, the IHP has progressively carried out activities on the quantity and quality of global/regional water resources, transboundary water resources management, mitigation of water related hazards, and water education. While addressing comprehensive areas over water challenges, greater emphasis has been placed on the role of water resources management for sustainable development and with respect to the expected changes in climate and environmental conditions. WWAP (World Water Assessment Programme) and its major product WWDR (World Water Development Report) in East Asia are under the framework of IHP which supports field oriented activities on monitoring freshwater, developing case studies, enhancing national assessment capacity, and facilitating decision making processes. In light of transboundary waters in IHP, RSC (Regional Steering Committee) plays a focal role for facilitating regional cooperation in the Southeast and East Asia and Pacific States. Furthermore, ISI (International Sediment Initiative) and IFI (International Flood Initiative) have significant roles, respectively, for the management of erosion and sedimentation in line with river system or reservoir management, and for the flood management focusing on capacity building of each country in East Asia. There are other major areas of concern under UNESCO’s IHP programme in East Asia, specifically in aspects including, mitigating water conflicts on transboundary aquifers through ISARM (International Shared Aquifer Resources Management), water management of arid areas through Water and Development Information for Arid Lands- A Global Network (Asian G-WADI), and sustainable management of groundwater by UNESCO Water Chair, as well as water education through the programme of Sustainable Water Integrated Management- Educational Component.  相似文献

The environmental performance of foreign direct investment (FDI) companies in the Pearl River Delta Region (PRDR) is examined through a case study of Dongguan City. The influence of host governments, regional/international organisations and export markets is highlighted in the analysis of environmental management systems of the FDI companies. The majority of FDI companies in the region lack effective systems and measures for environmental management. The environmental governance of the host country, the environment-related legislation and policies of the main export markets, and the social responsibility of the company owners are major factors that influence the environmental performance of the FDI companies. A combination of the quality of host government decision making in relation to sustainable development and the high degree of social responsibility and environmental awareness of individual FDI companies is crucial not only to achieving better overall environmental performance but also to achieving better environmental quality in the PRDR.  相似文献

国外空间规划研究与实践的新动向及对我国的启示   总被引:7,自引:0,他引:7  
空间规划是可持续发展必不可少的公共管理工具。20世纪90年代以来,人们认识到空间规划应该具有协调和整合空间发展的功能,而不仅仅是部门性的土地利用管理体系;应该关注地域的可持续发展,而不是一味地追求增长;应该关注不同利益人之间共识的形成,而不是简单地分析一定地域空间开发的适宜性和先后顺序。20世纪90年代以来国外空间规划实践的一些新动向: a) 重新分配空间规划的权利和职能; b)注重全纳性的参与; c) 重视空间规划的协调与整合; d)强化空间规划的环境维度; e)增强空间规划的灵活性。基于此对我国的空间规划实践得到几点启示: a)空间发展的战略框架和行动计划相结合; b)形成适合于我国的规划参与机制; c)在增强规划约束性的基础上增加灵活性; d)强化区域层次的空间规划; e)突出空间规划的公共管理职能。  相似文献

This paper examines the constitution of ‘sustainable management’ within the context of the New Zealand marine environment. Firstly this paper examines the difference between ‘sustainable ecosystems’ and ‘sustainable utilisation’. The distinction is important if we are to make sense of the different ways in which various stakeholders (fishers, fisheries companies, scientists, fisheries managers and environmental groups) use ‘sustainability’ in the management of New Zealand's marine environment. We then examine how contestation results in sustainable management becoming a governmentality. We propose that such contestation transforms stakeholders into subjects whose everyday practices and relationships are influenced by seemingly incommensurable understandings of the lexicon that surrounds sustainable management. We conclude try considering how the potential revelation of new unknowns may be needed in order for disparate stakeholders to forge a unified approach to New Zealand's marine management.  相似文献

This paper examines the recent economic turmoil in East Asia which has been linked to the convulsive nature of global capital movements. East Asia, once the site of rapid capital accumulation, lost its economic momentum beginning in July 1997 with a series of currency devaluations, culminating in a net outflow of private capital within a year. International capital's ability to disembed the region, however, has been highly uneven over space. That China, Hong Kong, Singapore, and Taiwan are far more territorially resilient while others like Indonesia, Thailand, and South Korea initiated major political changes suggests that the geography of crisis is far more complex than is currently presented.  相似文献

根据联合国粮农组织提供的1950-2015年非洲渔获生产统计数据,结合Fishbase提供的相关鱼种营养级(Trophic level, TL)以及Sea Around Us Project Database提供的海洋无脊椎动物营养级,探讨了1950-2015年北非、东非、南非、中非和西非的沿海国家渔获物平均营养级(Mean trophic level, MTL)的变化情况,以此来判定非洲沿海国海洋渔业资源的开发利用现状。结果表明:非洲沿海国家的海洋渔业资源开采大致经历开发不足、快速开发、过度开发阶段,1984-1991年,北非地区的海洋渔业资源遭到一定程度的破坏,高营养级渔业资源渔获量减少了33.5%,MTL由3.44降低到3.25;东非地区渔获量较其他4个区域低,目前,大部分鱼类资源处于充分捕捞利用状态;南非地区在21世纪初发生“捕捞降低海洋食物网”现象,2004-2015年,MTL恢复小幅上升趋势,渔业均衡指数(Fishing-in-balance index, FIB)趋于平稳;2013-2015年,中非地区的MTL与FIB均呈下降趋势,说明产量的增加速度不足以弥补营养级的降低,生态系统结构功能开始遭到破坏;1950-2015年,西非地区的渔获量不断增加,从上世纪60年代开始,过度捕捞现象愈加严重,低营养级鱼类数量占比呈先减少后增加趋势,2001-2012年,MTL波动下降,FIB平稳变化,说明MTL的下降由产量的增加而抵消。21世纪以来,部分北非、南非与西非沿海国家加强了资源管理,渔业资源状况有所好转。研究认为:渔获物平均营养级的下降主要由过度捕捞引起,非洲国家的管理不力加重了过度捕捞现象,建议非洲各国尽快建立起基于渔获物统计的海洋渔业资源实时监测系统,以便掌握捕捞活动下的鱼类群落结构的变动情况。  相似文献
