What is old is new again: the reintroduction of indigenous fishing technologies in British Columbia

In 2008, the Cowichan Tribes of British Columbia re-established a traditional fishing weir on the Cowichan River. After being banned by the Canadian Government for nearly 70 years, the reintroduction of the Cowichan weir has served to revitalise Cowichan cultural traditions, and after a century of hostility, is creating an opportunity for more collaborative approaches for salmon conservation. This paper demonstrates that the reintroduction of indigenous conservation practices into western systems of fisheries management can be complementary rather than conflicting to conservation objectives. However, while collaborative salmon conservation has been a positive outcome, the reintroduction of the Cowichan weir is also symbolic of the conflict that remains between the Cowichan and the Government of Canada over competing territorial claims, the legitimacy of an imposed western legal tradition, and the ultimate control of the Cowichan River fishery.     

案例城市环境基本公共服务与现状比较研究

日益严重的环境问题带来了越来越多的关注度,同时,以为公众提供良好的环境质量为目标的环境基本公共服务,也逐步进入人们的视野。环境基本公共服务是由政府或主要由政府提供的,保障公民最基本的环境权益的服务,包括环境基本公共硬服务和软服务两大方面,其内涵主要由公众、政府、相关企业三方之间的相互供求关系而决定。以环境基本公共服务的具体承载单元———城市为依托进行案例研究,选取纽约、新加坡、广州三所城市进行环境基本公共服务现状对比,结合中国环境基本公共服务外延性不足和无差别受益性两大特点,为中国加强环境基本公共服务水平提供建设性意见。     

The morality behind sustainability

The concepts of sustainable agriculture, organic agriculture, regenerative agriculture, and alternative agriculture are receiving increasing attention in the academic and popular literature on present trends and future directions of agriculture. Whatever the reasons for this interest, there nevertheless remain differences of opinion concerning what counts as a sustainable agriculture. One of the reasons for these differences is that the moral underpinnings of a policy of sustainability are not clear. By understanding the moral obligatoriness of sustainability, we can come to understand precisely what must be sustained, and by implication, how. This article discusses the arguments that can be advanced for sustaining anything and initially concludes that our obligations to future generations entail sustaining more than just sufficient food production or an adequate resource base. Indeed, a tradition of care and community must underlie whatever agricultural and resource strategies we are to develop under the rubric of sustainability. A consideration of the larger social and environmental system in which agriculture operates and the constraints this system places on agriculture forces us to recognize that sustainability has to do with larger institutional issues, including our ability to incorporate our common morality democratically into our institutions, practices, and technologies.     

山东临沂市集体林权改革环境影响调查研究—以小山口村、魏城村和南垛庄铺为例

本文选取小山口村、魏城村和南垛庄铺三个林权改革试点村作为调查对象,通过描述统计、交叉列联表分析和Ridit分析,就林权改革的方式、林改对经济和环境产生的影响及林权流转三个方面的问题对山东临沂市的集体林权制度改革现状展开调查研究。分析发现,在历经3年的林改中,临沂市始终坚持尊重实际、区别对待,灵活选择林权改革的方式,使当地的林权制度改革受到村民的欢迎。此外,林权改革后,当地的经济收入和生态环境及对林业的投入均有不同程度的提高和改善,村民的营林、护林积极性也大大增加。但是在涉及到林权流转方面的问题时,大部分的村民不能清楚认识到林权的价值,从而使落实处置权的目标短期内难以实现。     

公共资源与最优产权选择

公共资源是指在产权界定过程中，资源所有者被迫放弃或者没有进行产权界定的资源部分,而产权界定本质上是划分公共资源归属权的过程。根据组织对公共资源控制权的性质，将其分为两类——组织间公共资源和组织内公共资源，并据此将产权界定、生产和交易纳入同一个分析框架中。通过分析，认为随着公共资源范围的变化，不同产权形成一个相互联系和转化的系列，即从资源非稀缺条件下的纯公共产权到资源全为废弃物的纯公共产权系列；不可交易的所有权是产权系列中的特殊形式，私人产权和俱乐部产权是这一系列中的过渡形式；组织内和组织间的均衡博弈结构决定最优产权的具体选择形式。     

美国州法中的内径流水权及其优先权日问题

美国水资源的所有权属于各州 ,是一种公有的资源。法律上的水权 ,是水的使用权 ,主要包括私人所有的先占权水权、岸边权水权。在美国西部各州的水权系统中 ,有一种水权现在可以在私法框架中协调环境保护目标、各种取水权人的取水需求 ,这两者之间的冲突。这就是现在美国学术界广泛关注的内径流水权。内径流水权可以在私法领域保护水流的天然禀赋 ,并且排除政府以环境法为理由介入水事争端。随着环境主义在美国的破产[1] ,美国西部开始了大规模的水权裁决活动 ,通过水法院或者行政机构确认私有水权的优先权日 ,从而确立水权的优先权序列。这样水权就会真正成为属于分散的个体的、排他性的财产权。优先权日在先的水权将在枯水季节排除他人的取水权或者其他种类的用水权。因此 ,确立内径流水权在这个优先权序列中的地位 ,是环境保护目标在私法体系中 ,而不是在效率低下的各种环境保护法中 ,长久地得到维护的关键。内径流水权优先权日有 (1)判例法认定的日期 ;(2 )法律规定的日期 ;(3)转化生成的日期。在先占原则框架中扩张这种财产权可以更大程度地排除环境法的适用范围。     

自然权利的批判与辩护

环境伦理的突出功能表现在对人与自然关系的调整上。从法学视角切入．以“权利”作为分析文本．论述了人类中心主义与非人类中心主义在“自然权利”上的理论分歧．人类中心主义者从权利的一人性、权利义务的不对等性、主张自然权利的非现实性以及自然权利的不可操作性四个方面对自然的权利提出了批判．而非人类中心主义者指出权利撅念的在不断地扩展．人类中心主义不可能完全解决好人与自然的关系,自然权利存在着转化为在法律上具有可操作性的可能．并且自然权利理论已在法律实践领域拓展．对自然的权利进行了辩护。由此提出了“非人类中心主义”、“自然的权利”的环境伦理定位。     

浅析建立排污权有偿交易制度

随着工业化、城市化的快速推进,环境容量资源有限和社会经济持续较快发展的矛盾将长期存在。在充分运用必要的行政和法律手段的同时,应注重运用经济手段———排污权有偿使用和交易进行环境保护,使外部环境内部化,树立"容量有限、资源有价、使用有偿"的环境资源价值理念,推动企业自主创新和技术进步,降低企业内部治理成本,调动污染减排积极性,促进环境管理方式从粗放型向精细化转变,全面提升环境管理水平。     

Economic growth,international trade,and the depletion or conservation of renewable natural resources

Conservation of renewable natural resources and promotion of economic growth are both sustainable development goals. Here, we study the interdependency between economic growth, international trade, and the use of renewable natural resources—under alternative institutional settings of either open access or full property rights—in an endogenous growth model. We find that if the resource is depleted over time, consumption growth is reduced. Economic growth and international trade only impact resource use when the resource is harvested under full property rights. Then, widening international trade can lead countries to shift from conservation to depletion. Changes in the institutional setting of resource use in one country may have repercussions on trading partners. Our results indicate potential trade-offs between the sustainable development goals and imply that policies focusing on resource use or trade (e.g., international trade bans or certified trade) are not sufficient to prevent resource depletion.     

The development of first-possession rules in US mining, 1872–1920: theory, evidence, and policy implications

This paper applies a property rights framework to federal mineral lands in the western United States from the enactment of the Mining Law in 1872 until the enactment of the Mineral Leasing Act for fossil fuels in 1920. There are two principal findings. First, the Mining Law appears to have been an effective means for assigning rights to mineral stocks on public lands (at least through 1920). This conclusion is supported by evidence from claim disputes in the West. Second, the impetus for the Mineral Leasing Act did not derive from the different physical characteristics of hardrock minerals and petroleum. The relevance of these conclusions to contemporary mineral policy is also discussed.
