Legal Framework for Biosphere Reserves as Learning Sites for Sustainable Development: A Comparative Analysis of Ukraine and Sweden

The Biosphere Reserve (BR) concept aims at encouraging sustainable development (SD) towards sustainability on the ground by promoting three core functions: conservation, development, and logistic support. Sweden and Ukraine exemplify the diverse governance contexts that BRs need to cope with. We assessed how the BR concept and its core functions are captured in national legislations. The results show that the core functions are in different ways reflected in legal documents in both countries. While in Ukraine the BR concept is incorporated into legislation, in Sweden the concept is used as a soft law. In Ukraine managers desired stronger legal enforcement, while in Sweden managers avoided emphasis on legislation when collaborating with local stakeholders. Hence, BR implementation have adapted to different political cultures by development of diverse approaches. We conclude that a stronger legal support might not be needed for BRs, rather SD needs to be recognized as an integrated place-based process at multiple levels.     

From Resistance to Resilience: Media Discourses on Urban Flood Governance in Mexico

This article examines the continuities and changes in newspaper coverage of urban flood governance in Tabasco, southeastern Mexico, where highly destructive floods have made flood risks a socially sensitive and politically contested public issue. The analysis draws upon post-Foucauldian critical discourse analysis, paying special attention to different actors’ discursive strategies to further their agendas amid the shifting forms of environmental governance. We argue that in recent years, discourses that promote integrated flood governance, based on cultural adaptation and social resilience instead of technological control, have become prominent in the media presentation of flood governance. These discourses endorse neoliberal views of flood governance as an issue of public–private co-governance and civil self-responsibility while being reluctant to consider flood risk from the perspective of the uneven distribution of vulnerabilities or as an issue of human rights.     

Public Discourses of Climate Change in Hong Kong

The changing political environment in Hong Kong is likely to accelerate the transition in environmental policy discourse. Opportunities for critical public involvement are increasing and new environmental discourses are emerging. Yet, previous social surveys did not explore the range of these discourses and few focused on climate change. The paper outlines the public discourses of climate change in Hong Kong. Using Q-methodology, four distinctive discourses were identified, namely Pure Environmentalism, Political Pragmatism, Popular Optimism, and Fair Rationalism. While the first one is climate-centric, the other three are political or social in nature and do not indicate a clear or coherent climate orientation. This suggests that the climate change concern of the Hong Kong public is not tightly embedded into a coherent narrative of social and institutional transformation. Effective climate change governance and policies require strengthening the link between such concern and the public desires for social and institutional transformation. Bringing together the ongoing social movements and environmental campaigns will be instrumental to nurture an active climate citizenry.     

Adapting a holistic approach to flood management in the Hawkesbury–Nepean region: complexities and perceptions of the agencies involved

This paper looks into the complexity of managing flood risks in the Hawkesbury–Nepean catchment, Australia. Several aspects are explored: (1) the complexities created by the way different agencies are involved in assessing flood risks; (2) different perceptions on acceptable flood risk level; (3) community engagement in defining acceptable flood risk level; (4) views on a holistic flood risk management plan; and (5) challenges of a centralised information system. This study concludes that the complexity of managing a large catchment is exacerbated by the difference in the way professionals perceive the problem. This has led to (1) different standards for acceptable risks; (2) inconsistent attempt to set up a regional-scale flood management plan beyond the jurisdictional boundaries; (3) absence of a regional-scale agency with licence to share and update information; and (d) lack of forums for dialogue with insurance companies to ensure an integrated approach to flood management.

Why the Conservation of Forest Genetic Resources Has Not Worked

Abstract:  Genetic diversity is indispensable for long-term forest sustainability and is therefore mentioned in numerous binding and nonbinding political covenants calling for action. Nevertheless, there are significant obstacles to the conservation of forest genetic resources. We discuss hindrances to genetic conservation, mainly in Europe. We identified impediments by reviewing the literature and on the basis of the experiences of the authors in this field and their participation in related political processes. The impediments include (1) difficulties in assessing and monitoring genetic erosion and human impacts (e.g., by the lack of markers showing adaptive variation and the lack of record keeping on the use and transfer of forest-tree germplasm), (2) complexities of European national structures that make the development of a common strategy toward forest genetic conservation problematic, (3) lack of effective forest governance in many parts of the world, (4) the general unattractiveness of genes as flagships in raising public awareness, (5) lack of integration of genetic aspects into biodiversity conservation, and (6) the fact that scientists and politicians are often at cross-purposes. To overcome these impediments, forest geneticists and their peers in species conservation have to participate more actively in decision making. In doing so, they must be prepared to face challenges on 2 fronts: participating in political processes and the provision of significant research findings to ensure that decisions with respect to forest genetic diversity are politically implementable and effectively address targets.     

一次冷锋过程中我国区域空气污染边界层特征

利用常规地面气象和探空资料、ERA-interim再分析资料、以及全国PM_2.5浓度数据,针对2015年3月7~11日一次冷空气南下的锋面天气过程中,我国华北、华东地区出现的大范围空气污染,开展了高空各层天气形势分析,以及本次过程中污染区域由北至南6个城市（北京、章丘、郑州、南阳、武汉、长沙）边界层气象要素的垂直结构及其时空演变特征的研究.结果表明：在污染前期（3月7~8日）中高纬度500hPa平直的纬向环流和地面均压场,为污染天气的发生和维持以及空气污染物的集聚提供了有利的环流场.污染中期（3月8~10日）冷空气南下,地面冷高压向华东地区移动,重污染区域随冷高压前部的弱低压场或均压场由北向南移动.伴随着天气系统移动,六个地面观测站的边界层特征在时空上表现出相似性,由北向南各站在污染期间先后出现多层逆温,风速较小,逆温层下相对湿度较大.此次多层逆温的形成是由于夜间近地面辐射冷却、冷锋移动过程中产生的锋面逆温以及边界层以上的下沉运动造成的.本研究揭示了在天气系统移动中,位于天气系统相同部位站点的边界层结构具有共同的特征,及其与空气污染的关系.     

关于地方推进现代环境治理体系实践进展的述评

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。     

Addressing challenges for future strategic‐level emergency management: reframing,networking, and capacity‐building

The mounting frequency and intensity of natural hazards, alongside growing interdependencies between social‐technical and ecological systems, are placing increased pressure on emergency management. This is particularly true at the strategic level of emergency management, which involves planning for and managing non‐routine, high‐consequence events. Drawing on the literature, a survey, and interviews and workshops with Australia's senior emergency managers, this paper presents an analysis of five core challenges that these pressures are creating for strategic‐level emergency management. It argues that emphasising ‘emergency management’ as a primary adaptation strategy is a retrograde step that ignores the importance of addressing socio‐political drivers of vulnerabilities. Three key suggestions are presented that could assist the country's strategic‐level emergency management in tackling these challenges: (i) reframe emergency management as a component of disaster risk reduction rather than them being one and the same; (ii) adopt a network governance approach; and (iii) further develop the capacities of strategic‐level emergency managers.
