生物多样性问题日益严重,依靠单个国家难以解决,而必须依靠国际社会的共同努力。生物多样性是全球治理的一个重要对象和领域。国家是生物多样性全球治理的基本主体,政府间国际组织是生物多样性全球治理的重要主体,非政府组织和跨国公司是生物多样性全球治理的重要补充,它们均在生物多样性的全球治理中发挥着应有的作用。 相似文献

生物多样性是地球上所有生命形式的总合,它们对人类的生存和发展有至关重要的作用。因而对生物多样性的保护与研究,越来越引起全世界的重视。 1989年6月国际科联(ICSU)、环境问题委员会(SCOPE)与美国在华盛顿联合召开了《生物多样性的生态系统功能研讨会》(Workshop on Ecosystom Function of Biologioal Diversity)。1992年7月在巴西的里约热内卢召开的联合国环境与发展大会上,生物多样 相似文献

塔克拉玛干沙漠的生物多样性有限,但珍稀、特有种类较多;绝大多数植物群落的生存,制约于沙漠中的水分状况;其生态系统表现出明显的不稳定性和脆弱性;人为活动是塔克拉玛干沙漠生物多样性面临危机的根本原因;诸大河中下游是生物多样性保护的关键区域;塔克拉玛干沙漠的流动性、危害性和生物种类的贫乏性,决定了该区生物多样性的保护较一般地区更加重要;它是一项艰巨而伟大的事业,需要动员全社会的力量共同参与,并实行切实有效的保护措施。 相似文献

突破行政区划,构建跨域生态治理的有效实践机制是推进生态文明、建设美丽中国的迫切需要。数字技术建构了全新的治理场域,也形塑着新的治理模式。本文将跨域生态治理置于数字化时代的宏大视野,研究认为:传统跨域生态治理模式面临难以突破的“碎片化”瓶颈,主要表现为治理目标碎片化、治理资源碎片化和治理主体碎片化,究其原因在于利益失衡下的府际不合,“技”“智”缺位下的整合失力和能力动力双匮下的参与缺失。基于此,在系统解构整体性治理理论内涵的基础上,数字化时代跨域生态治理与整体性治理在价值、工具和场域方面存在高度耦合。最后,提出通过科学补偿和考核优化建立利益共享机制,通过资源整合与整体智治建立科学施策机制、信息共享与诉求回应建立多元协同机制,形塑整体性治理的协调、整合、信任机制,以期推进“碎片化”问题的弥合解决和跨域生态治理现代化的实现。 相似文献

外来物种入侵是威胁国家生物多样性、生态安全和公众健康的重大安全问题。《生物安全法》的通过为防治外来物种入侵提供了综合性的制度规范。我国防治外来物种入侵法治实践长期以行政规制为主导,较少关注司法机关、企事业单位、社会组织和公众等法律主体在治理中的作用。行政规制治理中执法机构及其职能与管理手段的碎片化,亦无法回应高风险社会防治外来物种入侵的需要。我国防治外来物种入侵法治建设应当坚持整体性治理理念,以整体安全观为指导,坚持风险预防、防治结合,明确综合管理程序及责任法律制度和一体化协同执法机制,健全防治外来物种入侵行政规制体系;引入公众参与,形成政府、企事业单位、社会组织和公众协同治理外来物种入侵,鼓励外来物种入侵公益诉讼等,完善防治外来物种入侵的多元共治体系,共促国家生物安全治理体系。 相似文献

While it is commonly acknowledged that the ecosystemic, and the inter- and intra-specific diversity of natural life is under threat of being irremediably lost, there is much less awareness that the diversity in agro-ecosystems is also under threat. This paper is focused on the biodiverse agro-ecosystems generated by landraces (LRs), i.e., farmer-developed populations of cultivated species that show among- and within-population diversity and are linked to traditional cultures. The aim of this work is to arouse concern about their loss, to explain how they can be conserved, and to discuss values that support maintaining and/or restoring on-farm agro-biodiversity. Although agriculture has relied on biodiverse agro-ecosystems for millennia, most of them have disappeared or are disappearing due to profound transformations in the socio-economic context. This is discussed with particular reference to the European situation. The positive values of LRs and LR systems that support their conservation are discussed along with possible objections. The conservation of LRs and LR systems can be well justified on ethical grounds. In particular, the complex intertwining of the biological and cultural contexts of LR systems, which continuously creates new adaptive responses to the changing socio-economic and eco-physical processes, is a value that strongly motivates conservation, particularly when the needs of future generations are considered. 相似文献

Local governments are under pressure to tackle an increasing spectrum of complex contemporary problems, such as climate change, while ensuring multiple stakeholder interests are incorporated into decision processes. Multi-criteria decision tools can assist, but challenges remain in creating an enabling environment for incorporating and balancing different stakeholder perspectives. Here, we draw on interview data and a sensitivity analysis to investigate the use of an evaluation matrix to guide local coastal adaptation decision-making in South Africa. We adopt a participatory action research framework and find that decision-making is influenced by individual, departmental and institutional values that are not adequately captured in the matrix approach. Our study reveals the compromise between achieving broad stakeholder representation and utilising technical expertise, and that altering matrix assumptions can imply different decision outcomes. Suggestions are made to improve multi-criteria decision approaches to better facilitate integrated coastal management in responding to local coastal adaptation challenges. 相似文献

In this paper, we present a comprehensive framework for analysing formal rules regulating the involvement of various actors in protected areas decision-making over time and apply it to Poland. Based on the analysis of legal acts and policy documents, we suggest that since the democratic transition started in 1989, the governance of Polish protected areas has been increasingly multi-level and participatory. However, different designations indicate different levels of involvement by non-state actors, with Natura 2000 standing out from the traditional protected areas. Regarding governance issues, establishing and taking management decisions were characterised by the greatest changes in actors’ involvement. While participation of non-public actors is still limited mostly to information and consultation, the involvement of non-state public actors of various levels increased significantly. The paper highlights the importance of a systematic analysis of legal rules as a starting point for empirical investigation of the governance of protected areas. 相似文献

The purpose of this study is to examine the impact of sustainable institutional investors (SIIs), based on their signatory status to the UN Principles for Responsible Investment (PRI), on corporate biodiversity disclosure (BD). Moreover, the moderating influence of sustainable board governance (critical mass of female directors, sustainability committees, and sustainability-related executive compensation) as a possible channel of the link between SIIs and BD is analyzed. The study is based on a European sample consisting of 2319 firm-year observations between 2014 and 2020 (EUROSTOXX 600) and embedded in a stakeholder agency theoretical framework. The results are in line with prior research on sustainable corporate governance and indicate that SIIs have a positive impact on BD and that the included sustainability board governance index strengthens this link. Our results are robust to a battery of sensitivity analyses. This study makes a major contribution to prior analyses, as it appears to be the first study on the link between SIIs and BD and the moderating impact of sustainable board governance. The study has major implications for business practice, regulators and research. 相似文献

为跟踪各地落实《关于构建现代环境治理体系的指导意见》的实践进展,本文通过比较各地发布的相关实施意见文本,结合实地调研座谈,总结典型案例,分析发现:(1)由于各地对现代环境治理体系内涵的理解存在差异,关注的重点领域有所不同,部分地方突破了“七大体系”。(2)实践中,在推动企业落实主体责任、优化政府监管服务、规范市场化建设、协同推进区域共建共保、激活基层治理效能、增强科学精准治理能力等方面形成了一些富有特色的实践经验。(3)《关于构建现代环境治理体系的指导意见》中的“七大体系”推进程度不均衡,政府、企业、社会组织和公众三大主体的力量结构失衡状态改善不明显,主要体现为“三多三少”,即政府责任体系和监管体系建设多,企业环境责任体系和社会治理体系建设少;关注规范第三方环境服务、落实“放管服”多,运用市场调节机制的案例少;社会治理以宣传活动和网格员机制多,践行绿色生活的全民行动体系成果少。为此,本文提出,加快建立环境治理体系现代化的评价体系,针对环境治理薄弱环节,协调推进“七大体系”建设等建议。 相似文献

The World Bank is the single largest source of development finance, with wide-reaching influence. The Bank's safeguards aim to minimize the negative impacts of the projects it funds. These policies have recently been updated in a new Environmental and Social Framework. For conservation, the key changes include a mechanism for the use of biodiversity offsets and borrowers’ own frameworks to manage impacts. Concerns have been raised that these changes may weaken protections as there is substantial flexibility about when offsets or borrowers’ frameworks can be used, and uncertainty around the efficacy of offsets. The project-by-project nature of these mechanisms and the lack of clear criteria may also hinder future efforts to hold the Bank to account. Concerns about these changes were raised by conservation organizations during the consultation process, but the framework's formulation does not fully reflect recommendations made. Although elements of the new policy have the potential to benefit conservation, the flexibility presents a risk to biodiversity. It is vital for conservation organizations to engage effectively to ensure that any negative impacts arising do not go unchallenged. 相似文献

随着国家政策导向提出实现生物多样性整体性、系统性保护的要求,新时期背景下的生物多样性保护除了注重实现生物多样性在自然生态系统、生物物种、遗传资源(基因)三方面的协同性整体性保护以外,还强调了实现自然生态系统平衡、维护国家安全等总体性目标。在此背景下,本文建议,生物多样性保护法律体系也应当在推动立法实践、提升国家安全治理能力、整合现有立法资源等方面发挥其应有价值。从系统性的角度出发,明确法律体系贯彻生物多样性整体性保护理念、执行国家战略部署以及平衡多元化利益的应有定位,并在此基础上从整体性目标的树立、网格联动性的体系构建、合理配置现行法律制度等方面探寻系统性法律体系的构建路径,将有效发挥我国生物多样性保护法律体系在服务社会需求、回应国家政策导向等方面的制度支撑价值。 相似文献
