Nordic National Climate Adaptation and Tourism Strategies – (How) Are They Interlinked?

The tourism sector is affected by climate change worldwide. Nordic tourism destinations offering various activities for tourists have also experienced changes, such as changing precipitation patterns, lack of snow in winter, and shifts in seasons. The tourism sector has to implement adaptation strategies but it is unclear whether the current public climate policy is sufficient to support considering adaptation actions. We reviewed national climate strategies of the Nordic countries from the perspectives of tourism, but excluding the transport sector. We also reviewed Nordic national tourism strategies from the perspective of climate change, particularly the extent to which they address climate adaptation concerns. We found out that the national climate strategies do not pay enough attention to tourism adaptation needs, nor do the national tourism strategies present adaptation actions that tourism actors could consider to implement. To connect these national level strategies, there is a need to review currently available and potential adaptation actions for tourism within the national adaptation framework supported by research based evidence. Next, by means of Nordic cooperation, guidance for both public and private tourism actors within and across Nordic countries can be provided. This can particularly enhance the competitiveness and resilience of the Nordic tourism supply and contribute to the development of economically, environmentally and socially sustainable tourism in the region

Vertical zonation of testate amoebae in the Elatia Mires, northern Greece : palaeoecological evidence for a wetland response to recent climate change or autogenic processes?

The Elatia Mires of northern Greece are unique ecosystems of high conservation value. The mires are climatically marginal and may be sensitive to changing hydroclimate, while northern Greece has experienced a significant increase in aridity since the late twentieth century. To investigate the impact of recent climatic change on the hydrology of the mires, the palaeoecological record was investigated from three near-surface monoliths extracted from two sites. Testate amoebae were analysed as sensitive indicators of hydrology. Results were interpreted using transfer function models to provide quantitative reconstructions of changing water table depth and pH. AMS radiocarbon dates and 210Pb suggest the peats were deposited within the last c. 50 years, but do not allow a secure chronology to be established. Results from all three profiles show a distinct shift towards a more xerophilic community particularly noted by increases in Euglypha species. Transfer function results infer a distinct lowering of water tables in this period. A hydrological response to recent climate change is a tenable hypothesis to explain this change; however other possible explanations include selective test decay, vertical zonation of living amoebae, ombrotrophication and local hydrological change. It is suggested that a peatland response to climatic change is the most probable hypothesis, showing the sensitivity of marginal peatlands to recent climatic change

A synthesis of atmospheric mercury depletion event chemistry in the atmosphere and snow

It was discovered in 1995 that, during the spring time, unexpectedly low concentrations of gaseous elemental mercury (GEM) occurred in the Arctic air. This was surprising for a pollutant known to have a long residence time in the atmosphere; however conditions appeared to exist in the Arctic that promoted this depletion of mercury (Hg). This phenomenon is termed atmospheric mercury depletion events (AMDEs) and its discovery has revolutionized our understanding of the cycling of Hg in Polar Regions while stimulating a significant amount of research to understand its impact to this fragile ecosystem. Shortly after the discovery was made in Canada, AMDEs were confirmed to occur throughout the Arctic, sub-Artic and Antarctic coasts. It is now known that, through a series of photochemically initiated reactions involving halogens, GEM is converted to a more reactive species and is subsequently associated to particles in the air and/or deposited to the polar environment. AMDEs are a means by which Hg is transferred from the atmosphere to the environment that was previously unknown. In this article we review Hg research taken place in Polar Regions pertaining to AMDEs, the methods used to collect Hg in different environmental media, research results of the current understanding of AMDEs from field, laboratory and modeling work, how Hg cycles around the environment after AMDEs, gaps in our current knowledge and the future impacts that AMDEs may have on polar environments. The research presented has shown that while considerable improvements in methodology to measure Hg have been made but the main limitation remains knowing the speciation of Hg in the various media. The processes that drive AMDEs and how they occur are discussed. As well, the role that the snow pack and the sea ice play in the cycling of Hg is presented. It has been found that deposition of Hg from AMDEs occurs at marine coasts and not far inland and that a fraction of the deposited Hg does not remain in the same form in the snow. Kinetic studies undertaken have demonstrated that bromine is the major oxidant depleting Hg in the atmosphere. Modeling results demonstrate that there is a significant deposition of Hg to Polar Regions as a result of AMDEs. Models have also shown that Hg is readily transported to the Arctic from source regions, at times during springtime when this environment is actively transforming Hg from the atmosphere to the snow and ice surfaces. The presence of significant amounts of methyl Hg in snow in the Arctic surrounding AMDEs is important because this species is the link between the environment and impacts to wildlife and humans. Further, much work on methylation and demethylation processes has occurred but these processes are not yet fully understood. Recent changes in the climate and sea ice cover in Polar Regions are likely to have strong effects on the cycling of Hg in this environment; however more research is needed to understand Hg processes in order to formulate meaningful predictions of these changes

An exploratory randomised controlled trial of a premises-level intervention to reduce alcohol-related harm including violence in the United Kingdom

<b>Background</b><p></p> To assess the feasibility of a randomised controlled trial of a licensed premises intervention to reduce severe intoxication and disorder; to establish effect sizes and identify appropriate approaches to the development and maintenance of a rigorous research design and intervention implementation.<p></p> <b>Methods</b><p></p> An exploratory two-armed parallel randomised controlled trial with a nested process evaluation. An audit of risk factors and a tailored action plan for high risk premises, with three month follow up audit and feedback. Thirty-two premises that had experienced at least one assault in the year prior to the intervention were recruited, match paired and randomly allocated to control or intervention group. Police violence data and data from a street survey of study premises’ customers, including measures of breath alcohol concentration and surveyor rated customer intoxication, were used to assess effect sizes for a future definitive trial. A nested process evaluation explored implementation barriers and the fidelity of the intervention with key stakeholders and senior staff in intervention premises using semi-structured interviews.<p></p> <b>Results</b><p></p> The process evaluation indicated implementation barriers and low fidelity, with a reluctance to implement the intervention and to submit to a formal risk audit. Power calculations suggest the intervention effect on violence and subjective intoxication would be raised to significance with a study size of 517 premises.<p></p> <b>Conclusions</b><p></p> It is methodologically feasible to conduct randomised controlled trials where licensed premises are the unit of allocation. However, lack of enthusiasm in senior premises staff indicates the need for intervention enforcement, rather than voluntary agreements, and on-going strategies to promote sustainability

Factors Driving Mercury Variability in the Arctic Atmosphere and Ocean over the Past 30 Years

[1] Long-term observations at Arctic sites (Alert and Zeppelin) show large interannual variability (IAV) in atmospheric mercury (Hg), implying a strong sensitivity of Hg to environmental factors and potentially to climate change. We use the GEOS-Chem global biogeochemical Hg model to interpret these observations and identify the principal drivers of spring and summer IAV in the Arctic atmosphere and surface ocean from 1979–2008. The model has moderate skill in simulating the observed atmospheric IAV at the two sites (r ~ 0.4) and successfully reproduces a long-term shift at Alert in the timing of the spring minimum from May to April (r = 0.7). Principal component analysis indicates that much of the IAV in the model can be explained by a single climate mode with high temperatures, low sea ice fraction, low cloudiness, and shallow boundary layer. This mode drives decreased bromine-driven deposition in spring and increased ocean evasion in summer. In the Arctic surface ocean, we find that the IAV for modeled total Hg is dominated by the meltwater flux of Hg previously deposited to sea ice, which is largest in years with high solar radiation (clear skies) and cold spring air temperature. Climate change in the Arctic is projected to result in increased cloudiness and strong warming in spring, which may thus lead to decreased Hg inputs to the Arctic Ocean. The effect of climate change on Hg discharges from Arctic rivers remains a major source of uncertainty.Earth and Planetary SciencesEngineering and Applied Science

Insurers' role in enhancing development and utilization of environmentally sound technologies: a case study of Nordic insurers

During the last decades numerous environmental problems have been exacerbated, and in some cases created. Traditionally, such problems have been addressed through environmentally sound technologies. The diffusion of such technologies has, however, been slow, where the focus has primarily been on high-polluting sectors. This paper explores the environmental actions of a relatively low-polluting sector, the insurer industry, in regards to environmentally sound technologies, by schematizing the concept of environmentally sound technologies as it is defined in Agenda 21. The Agenda 21 definition is critical when discussing environmentally sound technologies, as typologies of academic scholars are defined from the perspective of manufacturers ignoring the role of relatively low-polluting sectors when dealing with environmental issues. Five focus points from a climate change statement issued by the Nordic insurance industry are then integrated into the schematic framework. Case study examples from 16 Nordic insurance companies and secondary data of insurers' activities are used to illustrate insurers' role in enhancing development and utilization of environmentally sound technologies. Although the insurance industry offers many examples of its role in the development and utilization of environmentally sound technologies, this paper highlights the following points (1) there are still areas for improvements, (2) there is a large capacity that could be utilized, and (3) business opportunities are expected to increase once climate change consequences become more apparent. Due to the slow uptake of environmentally sound technologies, it is important to strengthen the focus on the role and obligation of low-polluting sectors as a part of the supporting infrastructure dealing with environmental sustainability issues. This paper shows the potential of opportunities arising from the synergies between environmentally sound technologies and finance and service providers to address such issues.Lara Johannsdottir, Brynhildur Davidsdottir, Michael E.Goodsite, Snjolfur Olafsso

Responses to Air Pollution Based on Historical and Current Policies in the EU and ASEAN

This review paper focuses on an important new question: how can climate change affect maritime and other cities of Southeast Asia, and what challenges and possible responses can be identified based on historical and current regional policies and action, especially with regard to air pollution? This review was undertaken as part of the ISDP and ISEAS sponsored initiative: Regional Cooperation in Environmental Protection: Lessons from Two Regions (EU and ASEAN). We examined the cases of the EU and ASEAN policies for the protection of air quality from a scientific practitioner’s point of view. We seek to ascertain if ASEAN can respond to regional human-induced environmental problems given existing problems of national sovereignty and the interest-based character of ASEAN-type associations, since ASEAN’s goal, in contrast to that of the EU, has been regional cooperation rather than regional integration. Both regions are responding differently to climate change and the global economic and environmental realities resulting from, or arising in reaction to, their policies (or lack thereof ). While the EU and ASEAN can and should learn from one another and their relations have been the subject of studies (see for example), there are still challenges to be addressed to effectively drive improvement of critical regional (air) pollution issues that may ultimately impact health and productivity. Each regional organization has in its own manner made exemplary efforts towards resolving environmental degradation within its own region and taken efforts to make a positive international impact, but there is still the need for international treaties and more local efforts to empower the regional visions. Our aim is to highlight the status of the respective policy frameworks and exemplify areas in which we can learn from one another in the field of air pollution, given its global relevance for climate change. We conclude by suggesting a strategic summary framework for future action. This paper is not meant to be a history of either EU or ASEAN policy; for this, the reader is referred instead to appropriate literature, most notably the EU Environmental Policy Handbook, especially the air quality chapter (3) with excellent background information on European Atmospheric Environment Policy
