全球碳市场发展中我国碳交易体系的构建

近年来,全球碳市场进程表现出存在分割格局、EUETS配额分配供求失衡、长期价格信号缺失、监管不力风险加大、CDM的改善等特征。我国作为碳排放大国,应结合我国国情,通过加强碳交易相关制度建设、构建碳交易总量管制与排放交易机制、培育多层次碳市场交易体系、鼓励金融机构参与碳市场、引导资金流向低碳领域等措施谋求碳定价权,把握我国碳市场发展主动权。

我国自然资源开发利用的成就和问题

1992年联合国环境与发展大会后,我国在资源利用与保护方面取得了很大成就,资源开发利用程度和利用效率不断提高,资源保护法制化步伐明显加快.但是,由于我国人口众多、人均占有资源量不足和后备资源缺乏,重要资源对社会经济发展的制约作用逐步加大,资源问题成为我国实现全面建设小康社会奋斗目标的"瓶颈".     

自然资源资产负债表编制的理论与实践

自然资源资产负债表在国内外都是一个全新的课题,然而学术界关于自然资源核算、环境经济核算、国家资产负债表编制和生态系统服务评估等方向的研究由来已久,为我国自然资源资产负债表的编制提供了大量可资借鉴的学术成果。本文在综述相关领域研究进展的基础上,基于会计学、经济学、资源环境科学等学科视角论述了自然资源资产负债表编制的理论基础,辨析了自然资源资产、负债和净资产等核心概念的内涵,从基本假设、表式结构、数据来源等方面探讨了自然资源资产负债表的框架体系,并回顾了当前自然资源资产负债表编制的实践经验,以期为深化自然资源资产负债表研究提供科学参考。

城市自然资源的综合评价与发展评价——以武汉市为例

在武汉市的自然资源结构中,水资源量大质优,地位突出,农业自然资源配合协调,城市建设的相关资源组合较好,能源与矿产资源相当贫乏。从城市发展的角度考察,人均资源量将日趋减少,水资源保证程度较高,城市土地资源尚具潜力但矛盾日益显露,能源与矿产资源的制约性是深刻而持久的。

Water,Adaptation, and Property Rights on the Snake and Klamath Rivers1

Abstract: Water demand in a viable economy tends to be dynamic: it changes over time in response to growth, drought, and social policy. Institutional capacity to re‐allocate water between users and uses under stress from multiple sources is a key concern. Climate change threatens to add to those stresses in snowmelt systems by changing the timing of runoff and possibly increasing the severity and duration of drought. This article examines Snake and Klamath River institutions for their ability to resolve conflict induced by demand growth, drought, and environmental constraints on water use. The study finds that private ownership of water rights has been a major positive factor in successful adaptation, by providing the basis for water marketing and by promoting the use of negotiation and markets rather than politics to resolve water conflict.

Is Policy Towards Intellectual Property Rights Addressing the Real Problems? The Case of Unauthorized Appropriation of Genetic Resources

Unauthorized appropriation of geneticresources has been described by the term``biopiracy.' Technological breakthroughsincluding biotechnological applications canincrease considerably the instrumental value ofbiodiversity as new products or products withnew properties can be made. Nevertheless, itappears that, in most cases, the properties inquestion were already known to the indigenouspeople and used for centuries. The analysisdiscusses both from an economic and an ethicalperspective whether it is just that traditionalknowledge is rewarded. As the conflictintensifies over questions of ownership andcontrol of biological materials, IntellectualProperty Rights are at the center ofcontroversies. The current global systemgoverning biotechnology has largely been shapedby Western expectations and valuations andconsequently has drawn severe criticism. Thecritics doubt both the stability andsustainability of the current patent system andargue for restructuring through benefit-sharingsystems in order to address some of theexisting inequalities. With the help of a casestudy (US patent no. 5,751 on ayahuasca) thetheoretical notion of biopiracy is applied toreal problems.     

流域管理:权力产权的外部性问题

水资源的自然、经济和社会属性要求政府对流域的开发和利用进行管理,以解决个体使用者的外部性问题.但实际上由于政府并不是只有单一目标的统一组织,在分权体制下,不同区域、部门的政府单元掌握着实际权力.由于权力也存在外部性,各管理区域、部门之间存在利益冲突,导致政府的管理失效.解决政府权力外部性的办法:一是要转变政府职能,改变政府的激励机制;二是严格界定各政府单元的权力界限,对流域进行统一管理.     

A Transactions Cost Approach to the Theoretical Foundations of Water Markets1

Abstract: Water marketing is often cited as a means of alleviating the stresses attached to allocation of water use. Frequently, marketing is suggested in a context that implies substitution of competitive markets for the allocation based on the prior appropriation doctrine. This study examines water marketing from the perspective of a transactions cost approach to the private and broad social agreements (contracts) that support water allocation. It examines the major behavioral challenges faced by any contract, and the alternative approaches to those challenges, with respect to water allocation. It also examines the impact of market design on the existence of externalities, costs imposed by transactions on society and individuals not party to the transaction. It finds that the most robust water market designs will be found in systems with sufficient property rights protection to support investment, sufficient hydrologic information to provide accurate analysis of third party effects, conjunctive management of surface and groundwater, and a governance structure capable of administering the rules while not determining outcomes.     

Variable Irrigation District Action in Water Trading

Irrigation districts (IDs) in the American west are highly diverse in their economic attributes and local water scarcity circumstances. This diversity may affect reallocative action via water transactions as scarcity rises. The institutional background defining and constraining IDs is described here. For a Texas study region the progress of permanent water right transfers involving IDs is documented and examined. An econometric analysis of multiple decades of ID water transfer activities in the Lower Rio Grande Valley finds that IDs with larger initial water right holdings and higher populations in nearby cities are more likely to participate in agricultural‐to‐municipal water transfer activities. The findings suggest that consolidation of smaller water right holding IDs may be an avenue for quickening the pace of reallocation, especially in more populated areas.     

Economic and Ecological Transformation Processes in East German Water Management Regimes: The Role of Property Rights and Governance Structures

As in many fen land regions in East Germany, long-standing intensive arable farming—enabled by reclamation—has caused soil deterioration and high water runoff in the Schraden region. The more than ten years of economic and political transformation that followed the breakdown of the socialist regime has worsened the situation and even added new problems. The visible consequences are droughts in the summer, waterlogged plots in the spring, and worn-down water management facilities that operate in an uncoordinated or even unauthorized way. Given the local public-good character of some features of the fen land, the common-pool character of the ecosystems intermittently scarce resource water, and the conflicting interests of regional stakeholders, it is argued that the reallocation of property rights over reclamation systems, together with ineffective coordination mechanisms, have caused the physical and institutional failure of the water management system and so impeded appropriate land use.

Buy Me a River: Purchasing Water Rights to Restore River Flows in the Western USA

In recent decades, public and private environmental entities have been purchasing or leasing water rights across the Western United States (U.S.) in efforts to restore river flows and aquatic ecosystems. The need to pay for flow restoration arises from the fact that state governments did not begin to reserve water for instream purposes until the 1970s, long after water rights had become over‐appropriated and flows were substantially depleted in most rivers. As a consequence, flow depletion has become the leading cause of fish endangerment in the U.S., including the imperilment of two‐thirds of all native fish species in the Colorado River system. This paper takes stock of the progress made in buying water for the environment, specifically by reviewing and analyzing more than 50 transactions executed by public and private entities and the sources of funding underpinning these transactions. We conclude that nongovernmental actors — such as environmental organizations and state water trusts — are integral to regional efforts to restore river flows; these nongovernmental actors executed more than two‐thirds of the transactions we documented. However, we also conclude that the long‐term success of these nongovernmental actors depends upon the availability of sustained public funding that enables them to build capacity and engage in the large number of transactions needed to restore flows across each state.
