有效和妥善地解决工程移民的搬迁和安置问题,不仅是水利事业顺利发展的关键,也是预防和减缓社会矛盾的关键.在改革开放时期,移民补偿问题的解决方式是前所未有的.为了解释这种移民补偿方式,本研究以湖南省洪江和碗米坡两个水电站的移民搬迁和安置过程为案例,从治理机制的角度进行分析.研究发现完成移民补偿的治理机制是一种包含了命令、交易、合作的混合机制.水电公司是水能开发的最大受益者,也是移民补偿的责任人,但它并不直接去完成移民补偿,而是将移民补偿的任务用合同的方式外包给市级政府.市级政府分解了从水电公司获得的任务和资金,并用行政命令要求下级政府完成补偿任务.县级政府分配了任务给乡镇政府,乡镇政府再分配任务给行政村.行政村的村委会接受任务后,将补偿资金转交给移民,并用村集体中的合作机制向移民提供耕地、宅基地等资源.这种混合式的治理机制使得移民补偿任务能够按期顺利完成,具有非常强的有效性.  相似文献

论我国滨海湿地综合性法律调整机制的构建   总被引:1,自引:0,他引:1  
滨海湿地是我国湿地的重要组成部分,具有多种生态功能。随着风险社会的到来,各种开发利用行为造成滨海湿地严重的环境资源问题,滨海湿地的保护管理和法制建设成为当务之急。法律调整机制是应对滨海湿地问题的各类调整机制中最重要的部分,但我国现行法律调整机制无法有效解决滨海湿地利用中的“公地悲剧”和利益平衡问题,应该根据社会发展的需要,采取行政调整、市场调整和社会调整相结合的综合性法律调整机制。环境治理理论的兴起和我国第三部门的发展为滨海湿地综合性法律调整机制的构建提供了理论依据和社会基础,应该通过发展滨海湿地区域的环保产业、建立生态补偿制度、完善公众参与环境影响评价的途径、构建滨海湿地的社区共管模式,综合运用行政指导、经济激励、公众参与等各种法律手段完善我国滨海湿地的保护管理  相似文献

Marine governance of oil transportation is complex. Due to difficulties in effectively monitoring procedures on vessels en voyage, incentives to save costs by not following established regulations on issues such as cleaning of tanks, crew size, and safe navigation may be substantial. The issue of problem structure is placed in focus, that is, to what degree the specific characteristics and complexity of intentional versus accidental oil spill risks affect institutional responses. It is shown that whereas the risk of accidental oil spills primarily has been met by technical requirements on the vessels in combination with Port State control, attempts have been made to curb intentional pollution by for example increased surveillance and smart governance mechanisms such as the No-Special-Fee system. It is suggested that environmental safety could be improved by increased use of smart governance mechanisms tightly adapted to key actors’ incentives to alter behavior in preferable directions.  相似文献

Protected areas are a key instrument for conservation. Despite this, they are vulnerable to risks associated with weak governance, land-use intensification, and climate change. We used a novel hierarchical optimization approach to identify priority areas for expanding the global protected area system that explicitly accounted for such risks while maximizing protection of all known terrestrial vertebrate species. To incorporate risk categories, we built on the minimum set problem, where the objective is to reach species distribution protection targets while accounting for 1 constraint, such as land cost or area. We expanded this approach to include multiple objectives accounting for risk in the problem formulation by treating each risk layer as a separate objective in the problem formulation. Reducing exposure to these risks required expanding the area of the global protected area system by 1.6% while still meeting conservation targets. Incorporating risks from weak governance drove the greatest changes in spatial priorities for protection, and incorporating risks from climate change required the largest increase (2.52%) in global protected area. Conserving wide-ranging species required countries with relatively strong governance to protect more land when they bordered nations with comparatively weak governance. Our results underscore the need for cross-jurisdictional coordination and demonstrate how risk can be efficiently incorporated into conservation planning.

The problem of forest degradation and loss has become the concern of many countries. To address this challenge, some collaborate in sustainable forest management. The most successful outcomes, however, are observed where local participation is an essential part of conservation efforts. In Ghana, forests have experienced various degrees of exploitation over the years, resulting in their ecological decline. Despite its designation as a protected area for biodiversity and ecosystem services, the Atewa Range Forest Reserve in Ghana has been significantly impacted by deforestation, illegal mining, and other destructive activities. The purpose of this paper is to examine ecologically based management approaches that could be adopted to generate beneficial outcomes for all forest stakeholders and actors in Ghana. The study sampled forest stakeholders in Kwabeng, the administrative capital of the Atewa West District, to understand forest governance challenges and outline strategies for overcoming them. The study revealed that a bottom-up all-inclusive approach to managing forest resources is necessary. This paper, therefore, proposes an integrated forest governance that prioritizes the UN Sustainable Development Goal 15—Life on Land-related to forest preservation.  相似文献

This research paper is an attempt to define and analyse the concept of the blue economy (BE) and its implications for achieving Sustainable Development Goals (SDGs). This study covers aspects such as building a blue economy to achieve SDGs, the importance of a healthy ocean for current and future generations, maintaining the momentum to save the ocean, achievements of the United Nations (UN) conference on the Sustainable Blue Economy, and the highlights of the UN World Water Development Report 2020. This study specifically analyses the health effects and threats to biodiversity, adaptation and mitigation, improved wastewater management, prioritizing water, accessing climate funds, water and climate change, and the relationship between the blue economy and UN SDGs as well as identification of key stakeholders. This is achieved through a detailed literature review on the blue economy that identifies global organizations working on creating a blue economy, elements of the blue economy and current development efforts, United Nations Convention on the Law of the Sea, sustainability and equity, ocean governance, international law and frameworks, and improvement in governance frameworks among other issues. The methodology used attempted to develop a macro, comprehensive, and systematic aggregate database at the country level on macro parameters, namely blue economy, blue finance, BE-SDGs linkages, water development, marine sector, SDGs data on SDG-14 (life underwater), SDG-6 (access to safe drinking water and sanitation), SDG-3 (good health and well-being), and optimal management of water resources through scientific techniques, such as building several small reservoirs instead of mega projects, develop small catchment dams and protect wetlands, soil management, micro catchment development, recharging of underground aquifers thus reducing the need for large dams, which has encountered challenges due to data limitations. The results of this research study emphasize broader stakeholder consultations at the global level to resolve the issues relating to blue economy, blue finance, and ocean governance. The most important conclusion and policy implications of the study are that international organizations including the United Nations, the Asian Development Bank, and the World Bank are working towards achieving the SDGs in general, and the blue economy, blue finance, and ocean governance in particular.  相似文献

碳排放峰值和碳中和的“30/60目标”对政府环境治理提出了更高的要求,如何从政府治理压力和治理能力的视角探寻其与碳减排的关系,为助力中国“双碳”目标的实现提供了新的思路。本文选取中国 30个省(区、市) 2010—2020年的面板数据,通过直接效应、中介效应、空间溢出效应系统考察了政府外部治理压力和内部治理能力对碳减排的协同影响路径。研究发现,外部治理压力和内部治理能力均显著降低了碳排放强度,且内外部治理双重维度产生了显著的协同减排效应,在运用倾向得分匹配法和工具变量法进行稳健性检验时,该结论依然成立。此外,内外部治理双重维度对碳减排的驱动作用因地区分布差异和产业结构差异而存在异质性。中介效应分析结果表明绿色技术创新是内外部治理双重维度降低碳排放强度的重要机制。空间溢出效应分析表明内外部治理双重维度对邻近地区的碳排放强度存在负向空间溢出效应。  相似文献

European forest policymaking is shaped by progressing European integration, yet with notable ideological divisions and diverging interests among countries. This paper focuses on the coalitional politics of key environmental forest issues: biodiversity conservation, timber legality, and climate protection policy. Combining the Advocacy Coalition Framework and the Shifting Coalition Theory, and informed by more than 186 key informant interviews and 73 policy documents spanning a 20-year timeframe, we examine the evolution of coalitional forest politics in Europe. We find that the basic line-up has remained stable: an environmental coalition supporting EU environmental forest policy integration and a forest sector coalition mostly opposing it. Still, strategic alliances across these coalitions have occurred for specific policy issues which have resulted in a gradual establishment of an EU environmental forest policy. We conclude with discussion of our findings and provide suggestions for further research.Supplementary InformationThe online version contains supplementary material available at 10.1007/s13280-021-01644-5.  相似文献

为探究供应链环境协同治理问题,本文从复杂适应系统视角分析了供应链环境协同治理中内部主体之间以及内外部主体间的协同作用机理,以此为基础构建了供应链环境协同治理模型。为探究协同治理机制在该模型中的实际成效,本文运用多主体仿真技术,对二级供应链模型进行仿真模拟,验证了协同治理在企业运营发展以及供应链整体环境绩效方面的提升作用,并针对协同模型中制造商零售商间减排成本分担系数进行调整,检验上下游企业间减排成本分担系数变化对供应链环境治理效果的影响。仿真结果显示,虽然供应链整体利润随着制造商承担的减排成本增加而增加,但供应链单位产值排放量却随之呈现先下降后上升的趋势,进一步验证了协同治理的效果。  相似文献
