Sustainable Tourism in Svalbard: Balancing economic growth, sustainability, and environmental governance

This commentary introduces a methodology and theoretical framework for studying how the tourism industry might balance the competing demands of economic growth and environ mental governance. We focus on the “balancing act” Svalbard tourism industry must play among sometimes competing demands of climate change mitigation and emissions from tourism, and of strict Norwegian environmental management policy and demands for increased tourism. While these are specific to Svalbard, the balancing act of competing needs is the core challenge of the UN Sustainability Goals giving this research global and pan-Arctic relevance. Through collaboration between two tourism organisations, the Association of Arctic Expedition Cruise Operators (AECO) and Visit Svalbard and an interdisciplinary team of scien tists, we will co-produce knowledge about how to innovate new opportunities while protecting the wilderness, the very backbone of tourism. This collaboration considers how policy, climate change, and local attitudes together may affect the tourism industry and helps to define and develop sustainable tourism operations and products. For instance, tourists may participate in environmental and community-related activities or “micro safaris” rather than a sole focus on charismatic megafauna. Policy discussions about tourism growth need to consider how local and national governments anticipate and navigate rapid social, political, and environmental changes.publishedVersio

Managing Svalbard Tourism: Inconsistencies and Conflicts of Interest

The Svalbard Archipelago has experienced a rapid increase in tourism-related activities over the past few decades. The Norwegian Government’s ambition to develop the Archipelago’s tourism industry offers multiple socio-economic opportunities. The development and scope of these tourism activities is affected by a complex governance system that entails strict environmental regulation and preparedness considerations. To understand the balance of goals across the national and international policy levels, we have mapped, reviewed, and analyzed the national and international regulations and agreements that affect tourism activities on Svalbard. The document analysis reveals the framework of natural and environmental consideration, access to areas and passage, requirements for organized outdoor activities, and regulatory tools. We discovered conflicts and internal inconsistencies in the way that Svalbard tourism has developed. It has been shaped by both economic growth and environmental preservation, without any specific business development objectives and goals or acceptable limits of environmental and social change in place. For tourism stakeholders, this might complicate any rational assessment of the balance between economic development and environmental status. The challenges we have identified are specific to Svalbard, but are likely to be similar in many other Arctic locations involved in tourism

Gender and Climate Change Research : Moving Beyond Transformative Adaptation

Publisher's note: The Arctic Yearbook is open access. Readers may download, distribute, photocopy, cite or excerpt this Arctic Yearbook material provided it is properly and fully credited; however, we do not allow commercial use or the making of derivatives.Research on how communities in the Arctic can overcome the challenge of climate change have traditionally employed adaptation frameworks. The ability of these groups to continue thriving in the Arctic is complicated by historical, social, economic, and political complexities - issues thoroughly addressed through the postcolonial feminist concept of transformation. This article critically examines contemporary research on climate and gender, and the extent to which feminist transformative concerns are addressed, thereby challenging systems and promoting power structures that recognize or benefit all segments of society. The article adopts an analytical strategy which combines two parallel instances of critical reflection on climate research, specifically, a systematic literature review of climate and gender studies in the Canadian Arctic, and the results of a round-table workshop of international climate experts and researchers on the state of climate change, adaptation and gender research in the Arctic. The article explores the results of these analyses and distinguishes those strategies that represent a continuation of status-quo power relations and climate adaptation processes from those that account for current economic and socio-political factors.publishedVersio

Island Communities’ Viability in the Arkhangelsk Oblast, Russian Arctic: The Role of Livelihoods and Social Capital

Since the collapse of the Soviet Union, local communities have been adapting to new political and socioeconomic realities. These changes have prompted dramatic outmigration among rural populations, especially in the Russian Arctic. Despite these changes, some communities remain viable, with some residents exploring new economic opportunities. This study uses findings from qualitative interviews to understand what factors shape community viability, interviewing residents and relevant regional stakeholders in two case areas in the Arkhangelsk oblast: the Solovetsky Archipelago in the White Sea and islands in the delta of the Northern Dvina River. The results indicate that community viability and the reluctance of community members to leave their traditional settlements are shaped by livelihoods, employment opportunities, and social capital. Social capital is characterized by such empirically identified factors as shared perceptions of change and a willingness to address changes, place attachment, and local values. We conclude that further development or enhancement of community viability and support for local livelihoods also depends on 1) bottom-up initiatives of engaged individuals and their access to economic support and 2) top-down investments that contribute to local value creation and employment opportunities

Assessing the carcinogenic potential of low-dose exposures to chemical mixtures in the environment: the challenge ahead.

Lifestyle factors are responsible for a considerable portion of cancer incidence worldwide, but credible estimates from the World Health Organization and the International Agency for Research on Cancer (IARC) suggest that the fraction of cancers attributable to toxic environmental exposures is between 7% and 19%. To explore the hypothesis that low-dose exposures to mixtures of chemicals in the environment may be combining to contribute to environmental carcinogenesis, we reviewed 11 hallmark phenotypes of cancer, multiple priority target sites for disruption in each area and prototypical chemical disruptors for all targets, this included dose-response characterizations, evidence of low-dose effects and cross-hallmark effects for all targets and chemicals. In total, 85 examples of chemicals were reviewed for actions on key pathways/mechanisms related to carcinogenesis. Only 15% (13/85) were found to have evidence of a dose-response threshold, whereas 59% (50/85) exerted low-dose effects. No dose-response information was found for the remaining 26% (22/85). Our analysis suggests that the cumulative effects of individual (non-carcinogenic) chemicals acting on different pathways, and a variety of related systems, organs, tissues and cells could plausibly conspire to produce carcinogenic synergies. Additional basic research on carcinogenesis and research focused on low-dose effects of chemical mixtures needs to be rigorously pursued before the merits of this hypothesis can be further advanced. However, the structure of the World Health Organization International Programme on Chemical Safety 'Mode of Action' framework should be revisited as it has inherent weaknesses that are not fully aligned with our current understanding of cancer biology

LSST Science Book, Version 2.0

A survey that can cover the sky in optical bands over wide fields to faint magnitudes with a fast cadence will enable many of the exciting science opportunities of the next decade. The Large Synoptic Survey Telescope (LSST) will have an effective aperture of 6.7 meters and an imaging camera with field of view of 9.6 deg^2, and will be devoted to a ten-year imaging survey over 20,000 deg^2 south of +15 deg. Each pointing will be imaged 2000 times with fifteen second exposures in six broad bands from 0.35 to 1.1 microns, to a total point-source depth of r~27.5. The LSST Science Book describes the basic parameters of the LSST hardware, software, and observing plans. The book discusses educational and outreach opportunities, then goes on to describe a broad range of science that LSST will revolutionize: mapping the inner and outer Solar System, stellar populations in the Milky Way and nearby galaxies, the structure of the Milky Way disk and halo and other objects in the Local Volume, transient and variable objects both at low and high redshift, and the properties of normal and active galaxies at low and high redshift. It then turns to far-field cosmological topics, exploring properties of supernovae to z~1, strong and weak lensing, the large-scale distribution of galaxies and baryon oscillations, and how these different probes may be combined to constrain cosmological models and the physics of dark energy.Comment: 596 pages.
