Seasonality of PCDD/Fs in the ambient air of Malopolska Region,southern Poland

Background, aim, and scope  

The aim of the study was to identify the impact of polychlorinated dibenzo-p-dioxin and furan (PCDD/F) emission sources on ambient air concentrations in the Malopolska Region, southern Poland. Three sites were selected: the city center of Krakow (Aleje), an industrial area (Nova Huta), and a rural site (Zakopane). In order to investigate the annual variations of PCDD/F sources, summer and winter time samples were taken.     

Transparency in global sustainability governance: to what effect?

ABSTRACT

Transparency in environmental governance is no longer an uncontroversial answer to problems of accountability and effectiveness. How to design effective transparency systems and in what policy contexts they are effective remain contested issues. This special section, consisting of this introduction and four research articles, interrogates complex and potentially conflicting links between transparency, accountability, empowerment and effectiveness in environmental governance. Building on existing literature and the four contributions, we discuss persisting diversity in varieties of transparency, the evolving dynamics of commodity chain transparency, and the consequences of emerging novel forms of digitalized transparency. As we show, the contributions to this special section interrogate in novel ways the transformative potential of transparency, through shedding light on the performative effects of transparency in ever more complex environmental governance contexts. These contexts may include, inter alia, the growing ubiquity of traceability in transnational commodity chains, the need for ever more anticipatory (ex-ante) forms of environmental governance, and an ever-broadening quest for digitally monitored environments. In particular, the impacts of the real-time ‘radical’ transparency engendered by use of novel digital technologies remain under-analyzed in the sustainability domain. We conclude by raising several critical concerns that deserve further scientific research and policy debate.     

Stress and the city: urbanization and its effects on the stress physiology in European blackbirds

Animals colonizing cities are exposed to many novel and potentially stressful situations. There is evidence that chronic stress can cause deleterious effects. Hence, wild animals would suffer from city life unless they adjusted their stress response to the conditions in a city. Here we show that European Blackbirds born in a city have a lower stress response than their forest conspecifics. We hand-raised urban and forest-living individuals of that species under identical conditions and tested their corticosterone stress response at an age of 5, 8, and 11 months. The results suggest that the difference is genetically determined, although early developmental effects cannot be excluded. Either way, the results support the idea that urbanization creates a shift in coping styles by changing the stress physiology of animals. The reduced stress response could be ubiquitous and, presumably, necessary for all animals that thrive in ecosystems exposed to frequent anthropogenic disturbances, such as those in urban areas.     

Spatial gradients of OCPs in European butter—integrating environmental and exposure information

The Stockholm Convention and the Global Monitoring Plan encourage the production of monitoring data to effectively evaluate the presence of the persistent organic pollutants (POPs) in all regions, in order to identify changes in levels over time, as well as to provide information on their regional and global environmental transport. Here, we report the first step of two to investigate whether butter is a feasible matrix to screen with the purpose to reflect regional ambient atmospheric air levels of POPs. The first step described here is to generate monitoring data; the second is to investigate the relationship between the two matrixes, i.e., POP concentrations in air and butter, which will be reported in another article published in this journal. Here, the 27 organochlorine pesticides listed under the Stockholm Convention have been analyzed in 75 butter samples from Europe. The general conclusions were as follows: Total organochlorine pesticide concentration is lower in butter from northern and central Europe. The spatial gradient of 1,1,1-trichloro-2,2-di(4-chlorophenyl)ethane and hexachlorocyclohexane is increasing in the eastern region of Europe (Romania, Bulgaria, and Ukraine), dieldrin towards France, and endosulfan levels were elevated on the Azores Island in the Atlantic Ocean. One butter sample from Romania exceeded the European Maximum Residue Limit value for lindane, but the other butter pesticide levels were all below the limit values. The dataset reported here can be used for the calibration of the air–grass–dairy products model, which would support the feasibility to use butter as biomonitor for measuring POP levels in ambient air.     

From conflict to resilience? Explaining recent changes in climate security discourse and practice

The recent rise of resilience thinking in climate security discourse and practice is examined and explained. Using the paradigmatic case of the United Kingdom, practitioners’ understandings of resilience are considered to show how these actors use a resilience lens to rearticulate earlier storylines of climate conflict in terms of complexity, decentralisation, and empowerment. Practitioners in the climate security field tend to reinterpret resilience in line with their established routines. As a result, climate resilience storylines and practices turn out to be much more diverse and messy than is suggested in the conceptual literature. Building on these findings, the recent success of resilience thinking in climate security discourse is explained. Climate resilience – not despite but due to its messiness – is able to bring together a wide range of actors, traditionally standing at opposite ends of the climate security debate. Through resilience storylines, climate security discourse becomes something to which a wide range of actors, ranging from security to the development field, can relate.     

Wintering Waterbirds and Recreationists in Natural Areas: A Sociological Approach to the Awareness of Bird Disturbance

Disturbance to wintering birds by human recreational activities has become a major concern for managers of many natural areas. Few studies have examined how recreationists perceive their effects on birds, although this impacts their behavior on natural areas. We surveyed 312 users on two coastal ornithological sites in Brittany, France, to investigate their perception of the effects of human activities on wintering birds. The results show that the awareness of environmental issues and knowledge of bird disturbance depends on the socioeconomic characteristics of each user group, both between the two sites and within each site. Results also indicate that, whatever the site and the user group, the vast majority of the respondents (77.6 %) believed that their own presence had no adverse effects on the local bird population. Various arguments were put forward to justify the users’ own harmlessness. Objective information on recreationists’ awareness of environmental issues, and particularly on their own impact on birds, is important to guide managers in their choice of the most appropriate visitor educational programs. We recommend developing global but also specific educational information for each type of user to raise awareness of their own impact on birds.     

The constitution of power in Norway's protected areas: on shore and in the sea

This article aims at comparing power resources that opponents to environmental policy apply in shaping and constructing discourses that contest the implementation of marine and terrestrial area protection. Document analyses and qualitative interviews have been undertaken with key actors and documents in two case areas to show how actors, knowledge, and financial and organisational capacities are introduced in the planning processes in order to contest the dominating environmental discourse established by environmental authorities. The results demonstrate how opponents to the terrestrial case were rather fragmented, consisting of a wide range of local and regional actors with various interests and agendas, and without substantial financial and organisational strength. Here, the environmental administration managed to create a partnership with local authorities that eventually proclaimed the national park as a win–win situation for local society. As a contrast, the opponents to the marine case had strong organisational, financial and even scientific capacities that were effectively unified with local authorities in the Skjerstad fjord. Here, the win–win situation was not accepted by the local parties. Together, these resources seemed to explain some of the variance in institutional responses in environmental administration, and finally different outcomes of the two cases.
