《中共中央关于制定国民经济和社会发展第十四个五年规划和二〇三五年远景目标的建议》的"三新"核心要义(即立足新发展阶段、贯彻新发展理念、构建新发展格局)对"十四五"土壤污染综合防治具有深刻影响。本文分析了"三新"核心要义为"十四五"土壤污染防治带来的历史发展机遇和挑战,分析了"十四五"土壤污染防治新阶段四个方面的特点。在此基础上提出了"十四五"土壤污染防治主要思路,重点分析了深入实施保护、预防、管控、修复四大行动的主要任务要求,以期为国家和各级政府开展"十四五"土壤污染防治谋划与设计提供决策参考。  相似文献

全球化的今天,以欧盟化学品注册、评估、许可制度(REACH)为代表的化学品环境管理政策和制度日益显示出广泛的国际影响;POPs公约等国际公约的签署、全球统一的化学品分类和标识系统(GHS)的推广及国际化学品管理战略步骤(SAICM)的提出愈发表明,化学品环境管理正呈现出各国联动、彼此影响的全球治理格局.但作为世界化学品生产和使用大国,我国化学品产业发展和管理水平落后,化学品环境污染及健康风险问题日渐突出,主要表现在:以职业安全管理为主体的化学品管理体制相对落后,化学品环境管理立法薄弱,制度不健全.研究认为,推行GHS系统,建立专门化学品环境管理行政法规或综合法律,建立行政协调机制及现有化学品风险评价、优先风险管理以及污染排放、转移和登记(PRTR)制度,完善有毒污染物环境监测制度和重大危险源管理制度,加强新化学品申报登记管理相关制度间的协调,将是中国化学品环境管理发展完善的重要方面.   相似文献

During the past decades, the traditional state monopoly in urban water management has been debated heavily, resulting in different forms and degrees of private sector involvement across the globe. Since the 1990s, China has also started experiments with new modes of urban water service management and governance in which the private sector is involved. It is premature to conclude whether the various forms of private sector involvement will successfully overcome the major problems (capital shortage, inefficient operation, and service quality) in China’s water sector. But at the same time, private sector involvement in water provisioning and waste water treatments seems to have become mainstream in transitional China.  相似文献

ABSTRACT

Engaging with normative questions in land system science is a key challenge. This debate paper highlights the potential of incorporating elements of environmental justice scholarship into the evolving telecoupling framework that focuses on distant interactions in land systems. We first expose the reasons why environmental justice matters in understanding telecoupled systems, and the relevant approaches suited to mainstream environmental justice into telecoupled contexts. We then explore which specific elements of environmental justice need to be incorporated into telecoupling research. We focus on 1) the distribution of social-ecological burdens and benefits across distances, 2) power and justice issues in governing distantly tied systems, and 3) recognition issues in information flows, framings and discourses across distances. We conclude our paper highlighting key mechanisms to address injustices in telecoupled land systems.  相似文献

ABSTRACT

European climate policy faced increasing constraints during the economic and Eurozone crises (2008–2014). The European Commission subsequently refocused policymaking toward integrating climate objectives into other policy areas such as energy and the 2014–2020 European Union (EU) budget. The conditions for successful climate policy integration (CPI) are analyzed, focusing on the compatibility of key actors’ beliefs. In renewable energy policy, CPI was successful as long as the co-benefits and related policy-core beliefs of energy security, rural economic development and climate action coexisted harmoniously. Once conflict among these policy-core beliefs emerged during the biofuels controversy, CPI was weakened as actors with competing economy-focused beliefs controlled the decision-making process. The case of EU budget climate mainstreaming illustrates how actors can add climate objectives into legislation despite meaningful discussion being ‘crowded out’ by other priorities. The findings highlight the importance of low conflict between departments, compatible beliefs and policy priorities for successful CPI.  相似文献

ABSTRACT

Policy evaluation has grown significantly in the EU environmental sector since the 1990s. In identifying and exploring the putative drivers behind its rise – a desire to learn, a quest for greater accountability, and a wish to manipulate political opportunity structures – new ground is broken by examining how and why the existing literatures on these drivers have largely studied them in isolation. The complementarities and potential tensions between the three drivers are then addressed in order to advance existing research, drawing on emerging empirical examples in climate policy, a very dynamic area of evaluation activity in the EU. The conclusions suggest that future studies should explore the interactions between the three drivers to open up new and exciting research opportunities in order to comprehend contemporary environmental policy and politics in the EU.  相似文献

Abstract:  In the first comprehensive reviews since 1969, two high-level reports on the status of U.S. marine ecosystems and resources have been released: that of the nongovernmental Pew Oceans Commission in 2003 and that of the congressionally mandated U.S. Commission on Ocean Policy in 2004 . Although the two commissions differed in the breadth and depth of their mandates, their findings on the state of our oceans and need for new management approaches are similar, and their major recommendations for science, governance, management and conservation, and education echo and reinforce each other. The history behind the two commissions and the structure and objectives of each remind us of the crucial roles conservation practitioners and scientists must play in the implementation of report recommendations. The reports suggest priorities for conservation practitioners to improve science, management, conservation, governance, and education to better manage and protect ocean resources and ecosystems. To redirect activities affecting the state of global marine resources, integrated research; education and outreach by terrestrial, aquatic, and marine conservation practitioners; and a clear definition of their roles in the implementation of recommendations is essential. Marine ecosystems provide a test case of society's ability to manage complexity in human and natural systems in an integrated manner, with extensive opportunities for participation by conservation practitioners from all disciplines.  相似文献

Policy scholars have indicated that the quality of the solution to a perceived social problem depends on the adequacy of its framing. This paper examines how policy stakeholders and local residents frame the issue of the radioactive waste storage facility in Taiwan, the limits of institutional mechanisms in decision-making processes, and the implications of the deliberative forums undertaken by the national Stop Nukes Now organisation. The controversy illustrates the problems of a knowledge gap and the top-down procedures as well as the challenges that Taiwan faces in becoming a nuclear-free country. This case demonstrates civic society organisations’ efforts to challenge the ‘social–technical divide’ and technical experts’ prior definition of the ‘problems’ and selection of a ‘solution’. Deliberative forums enable the participation of affected communities to shape public discourses, which helps to strengthen public communication, improves citizen consciousness of nuclear waste issues, and attempts to link wider communities and public interests.  相似文献
