Future heat-related climate change impacts on tourism industry in Cyprus

Tourism is a vital sector of Cyprus economy, attracting millions of tourists every year and providing economic growth and employment for the country. The aim of this study was to investigate the impacts of projected climate change in the tourism industry in Cyprus (Republic of Cyprus) using both “Tourism Climate Index” (TCI) and “Beach Climate Index” (BCI). TCI refers to tourism activities mainly related to sightseeing, nature-based tourism, and religious tourism etc., while BCI represents beach tourism that constitutes 85 % of tourism activities in Cyprus. The projections of climate change impacts in tourism are performed for 2071–2100 period, using regional climate model output employing the A1B greenhouse gas emissions scenario. The 1961–1990 period is used as the control run to compare the respective results of the future projections. The significant warming anticipated in the distant future (increases in annual and summer temperatures close to 4 °C) will have adverse impacts on Cyprus tourism industry regarding sightseeing tourism. TCI results for the distant future period show only acceptable conditions for general tourism activities during summer in contrast with the good/very good conditions in the present climate. Conversely, this type of tourism seems to be benefited in shoulder seasons, i.e., during spring and autumn; TCI and hence tourist activities improve in the distant future in relation to the present climate. On the other hand, concerning beach tourism, future projections indicate that it will not be negatively affected by future climate change and any changes will be positive.     

The contribution of the sciences,technology and innovation to sustainable development: the application of sustainability science from the perspective of UNESCO’s experience

The contribution of scientific knowledge and innovation to sustainability is demonstrated. Theory, discoveries, programmes and activities in both the natural as well as social sciences fields have greatly helped with the environmental, economic and social challenges of the past and current centuries, especially in the past 50 years or so. Nowadays, we increasingly realize the intimate link between science and society, and the need not only for science to inform policy but also to address requests by governments and the multiple stakeholders confronted with the challenge to achieve sustainable development. Current barriers to how science is conceived and related education is delivered hamper true interdisciplinarity, and the emerging field of sustainability science attempts inter alia to clarify how ‘a new generation of science’ can be designed so as to promote more integrated thinking to tackle complex societal issues. At the international level, and more specifically in the context of the United Nations, the practice of science has always entailed the need to solve problems such as climate change, ozone depletion, disaster risk, lack of food security, biodiversity loss, social instability and ineffective governance—to cite a few. In this regard, science in an intergovernmental context is by definition science that has to assist with the struggle for sustainability. Yet, a higher level of integration and cross-fertilization among disciplines as well as of participation among concerned stakeholders in the design and implementation of science-based programmes and activities carried out by the United Nations (and, in this article, the specific case of its Educational, Scientific and Cultural Organization—UNESCO—is presented) seems to be needed. The debate on sustainability science carried out in the academic circle and the experience of UNESCO in this area can be mutually supportive in further elucidating how, practically, the approach of sustainability science can enhance the achievement of sustainable development at multiple scales.     

How can winter tourism adapt to climate change in Saxony’s mountains?

This study deals with regional climate change in five low mountain areas in Eastern Germany and assesses the awareness of tourism professionals towards climate change, its impact on winter tourism and adaptation options. Favourable conditions for winter tourism decreased over the last decades in the Saxon low mountain ranges. A change from predominantly snow-based to a wider variety of winter tourism options appears indispensible as climate models project continuing warming. Diversifying touristic options provides opportunities to develop new business fields and to attract new target groups. This paper reveals obstacles and opportunities to adapt and develop winter tourism in the central European low mountain ranges and to increase the competitiveness of regional tourism. A survey explored the current awareness of representatives of most of the Saxon downhill skiing areas and of selected winter tourism municipalities towards climate change and its implications on their business. Awareness is essential to successfully implement adaptation measures. About half of the interviewees were not aware of the regional changes in natural snow conditions projected for the next 15–20 years. Nevertheless, the majority recognized climate change as a serious issue. Yet, stakeholders repeatedly emphasized their uncertainty about related scientific facts. They attributed their perception to mass media reports that suggest a lack of scientific consensus on climate change issues. Adaptation options for slope-based and general winter tourism are developed and presented, involving ideas of the interviewees. To successfully move towards adaptation, supply and marketing of alternative offers need to be strengthened. A survey of tourist expectations is planned to ensure a successful implementation of new (winter) touristic offers in the Saxon mountains.     

Climate change and human health in Latin America: drivers, effects, and policies

Many people would be increasingly affected by living under critical conditions in Latin America if, as expected, global warming aggravates disease and pest transmission processes. Heat waves and air pollution would increase heat-related diseases and illness episodes in large cities. Fire smoke has been associated with irritation of the throat, lung and eyes, and respiratory problems. Climate extreme increases associated with climate change would cause physical damage, population displacement, and adverse effects on food production, freshwater availability and quality. It would also increase the risks of infectious and vector-borne diseases. Climate change impacts the geographical range, seasonality, and the incidence rate of vector-borne diseases, such as malaria. Climate-related ecological changes may expand cholera transmission, particularly among populations in low-laying tropical coastal areas. El Niño conditions may affect the incidence of infectious diseases, such as malaria. Ocean warming would increase temperature-sensitive toxins produced by phytoplankton, which could cause more frequent contamination of seafood. A clearer understanding on the current role of climate change in disease patterns will be able to improve forecasts of potential future impacts of projected climate change and support action to reduce such impacts.     

Prepared for climate change? A method for the ex-ante assessment of formal responsibilities for climate adaptation in specific sectors

Climate change-related risks encompass an intensification of extreme weather events, such as fluvial and pluvial flooding, droughts, storms, and heat stress. A transparent and comprehensive division of responsibilities is a necessary—but not the only—precondition for being prepared for climate change. In this paper, we present, and preliminarily test, a method for the ex-ante assessment of the division of public and private responsibilities for climate adaptation in terms of comprehensiveness, transparency, legitimacy, and effectiveness. This method proofs particularly suited for the assessment of adaptation responsibilities in combination with a sectoral approach. It helps identifying a number of shortcomings in divisions of responsibilities for climate adaptation. We conclude that this method is useful as a diagnostic tool for identifying the expected climate change preparedness level, and recommend to combine this with ex-post analyses of real-life cases of extreme events in order to assess the actual preparedness for climate change. Besides the scientific purpose of providing a generally applicable assessment method, with this method, we also intend to assist policy-makers in developing and implementing adaptation plans at various levels.     

Nature and fate of Hudson Bay permafrost

Two aspects of the permafrost of the Hudson Bay region are examined. The first is the climatological conditions that support permafrost especially along the southwestern shore of Hudson Bay. The second is the fate of the permafrost using recent climate change scenarios. The continuous permafrost along the shores of southwestern Hudson Bay is examined from a climatological perspective. Two hypotheses are explored to explain the presence of continuous permafrost in this region in spite of the relatively "warm" local climate. Possible errors in the calculation of thawing degree days and the asymmetries in frozen and unfrozen soil thermal conductivities are successively examined. Only the second hypothesis is likely to explain the presence of permafrost in southwestern Hudson Bay. Sophisticated climate models are used to assess the potential change in permafrost distribution in the Hudson Bay region. Nine simulations using three different versions of the Canadian Centre of Climate Modelling and Analysis (CCCma) general circulation model are used to project permafrost distribution. Two surface temperature thresholds, –5 and –10 °C, are used to diagnose permafrost grid points. All simulations, including those that include reduction of CO₂ emissions, showed at least a 50% reduction of permafrost by 2100 using these temperature thresholds. Electronic Publication     

An integrated assessment of climate change impacts for Greece in the near future

Climate changes in the Mediterranean region, related to a significant increase in temperature and changes in precipitation patterns, can potentially affect local economies. Agriculture and tourism are undoubtedly the most important economic sources for Greece and these may be more strongly affected by changing future climate conditions. Climate change and their various negative impacts on human life are also detected in their environment; hence this study deals with implications, caused by changing climate, in urban and forest areas. Potential changes for the mid-twenty-first century (2021–2050) are analysed using a high-resolution regional climate model. This paper presents relevant climatic indices, indicative for potential implications which may jeopardise vital economic/environmental sectors of the country. The results provide insights into particular regions of the Greek territory that may undergo substantial impacts due to climate change. It is concluded that the duration of dry days is expected to increase in most of the studied agricultural regions. Winter precipitation generally decreases, whereas an increase in autumn precipitation is projected in most areas. Changing climate conditions associated with increased minimum temperatures (approximately 1.3°C) and decreased winter precipitation by 15% on average suggest that the risk for forest fires is intensified in the future. In urban areas, unpleasantly high temperatures during day and night will increase the feeling of discomfort in the citizens, while flash floods events are expected to occur more frequently. Another impact of climate change in urban regions is the increasing energy demand for cooling in summer. Finally, it was found that continental tourist areas of the Greek mainland will more often face heatwave episodes. In coastal regions, increased temperatures especially at night in combination with high levels of relative humidity can lead to conditions that are nothing less than uncomfortable for foreigners and the local population. In general, projected changes associated with temperature have a higher degree of confidence than those associated with precipitation.

Future climate and adverse health effects caused by fine particulate matter air pollution: case study for Poland

Ground level air pollution, especially fine particulate matter (PM_2.5), has been associated with a number of adverse health effects. The dispersion of PM_2.5 through the atmosphere depends on several mutually connected anthropogenic, geophysical and meteorological parameters, all of which are affected by climate change. This study examines how projected climate change would affect population exposure to PM_2.5 air pollution in Poland. Population exposure to PM_2.5 in Poland was estimated for three decades: the 1990s, 2040s and 2090s. Future climate conditions were projected by Regional Climate Model RegCM (Beta), forced by the general atmospheric circulation model ECHAM5. The dispersion of PM_2.5 was simulated with chemical transport model CAMx version 4.40. Population exposure estimates of PM_2.5 were 18.3, 17.2 and 17.1 μg/m³ for the 1990s, 2040s and 2090s, respectively. PM_2.5 air pollution was estimated to cause approximately 39,800 premature deaths in the population of Poland in the year 2000. Our results indicate that in Poland, climate change may reduce the levels of exposure to anthropogenic particulate air pollution in future decades and that this reduction will reduce adverse health effects caused by the air pollution.

Impact of climate change on vulnerability of forests and ecosystem service supply in Western Rhodopes Mountains

The vulnerability of forest ecosystem services to climate change is expected to depend on landscape characteristic and management history, but may also be influenced by the proximity to the southern range limit of constituent tree species. In the Western Rhodopes in South Bulgaria, Norway spruce is an important commercial species, but is approaching its current southern limit. Using climate sensitive forest models, we projected the impact of climate change on timber production, carbon storage, biodiversity and soil retention in two representative landscapes in the Western Rhodopes; a lower elevation landscape (1000–1450 m a.s.l) dominated by mixed species forests, and a higher elevation landscape (1550–2100 m a.s.l.) currently dominated by spruce. In both landscapes climate change is projected to induce a shift in forest composition, with drought-sensitive species, such as Norway spruce, being replaced by more drought-tolerant species such as Scots pine and black pine at lower elevations. In the higher elevation landscape a reduction in spruce growth is projected, particularly under the more severe climate change scenarios. Under most climate scenarios a reduction in growing stock is projected to occur, but under some scenarios a moderate increase in higher elevation stands (>1500 m a.s.l.) is expected. Climate change is projected to negatively influence carbon storage potential across landscapes with the magnitude depending on the severity of the climate change scenario. The impact of climate change on forest diversity and habitat availability is projected to differ considerably between the two landscapes, with diversity and habitat quality generally increasing at higher elevations, and being reduced at lower elevations. Our results suggest that if currently management practices are maintained the sensitivity of forests and forest ecosystem services in the Western Rhodopes to climate change will differ between low and higher elevation sites and will depend strongly on current forest composition.     

The impact of climate change on tourism in Germany,the UK and Ireland: a simulation study

We downscale the results of a global tourism simulation model at a national resolution to a regional resolution. We use this to investigate the impact of climate change on the regions of Germany, Ireland and the UK. Because of climate change, tourists from all three countries would spend more holidays in the home country. In all three countries, climate change would first reduce the number of international arrivals—as Western European international tourist demand falls—but later increase numbers—as tourism demand from increasingly rich tropical countries grows. In Ireland and the UK, the regional pattern of demand shifts is similar to the international one: tourism shifts north. In Germany, the opposite pattern is observed as the continental interior warms faster than the coast: tourism shifts south.

Climate Adaptation Services for the Netherlands: an operational approach to support spatial adaptation planning

There is a growing availability of climate change information, offered to scientists and policy makers through climate services. However, climate services are not well taken up by the policy-making and planning community. Climate services focus on primary impacts of climate change, e.g., the disclosure of precipitation and temperature data, and this seems insufficient in meeting their needs. In this paper, we argue that, in order to reach the spatial planning community, climate services should take on a wider perspective by translating climate data to policy-relevant indicators and by offering support in the design of adaptation strategies. We argue there should be more focus on translating consequences of climate change to land-use claims and subsequently discuss the validity, consequences and implications of these claims with stakeholders, so they can play a role in spatial planning processes where much of the climate adaptation takes place. The term Climate Adaptation Services is introduced as being a stepwise approach supporting the assessment of vulnerability in a wider perspective and include the design and appraisal of adaptation strategies in a multi-stakeholder setting. We developed the Climate Adaptation Atlas and the Climate Ateliers as tools within the Climate Adaptation Services approach to support decision-making and planning processes. In this paper, we describe the different steps of our approach and report how some of the challenges were addressed.     

Effects of climate change on species distribution, community structure, and conservation of birds in protected areas in Colombia

Climate change is expected to cause shifts in species distributions worldwide, threatening their viability due to range reductions and altering their representation in protected areas. Biodiversity hotspots might be particularly vulnerable to climate change because they hold large numbers of species with small ranges which could contract even further as species track their optimal habitat. In this study, we assessed the extent to which climate change could cause distribution shifts in threatened and range-restricted birds in Colombia, a megadiverse region that includes the Tropical Andes and Tumbes-Choco-Magdalena hotspots. To evaluate how climate change might influence species in this region, we developed species distribution models using MAXENT. Species are projected to lose on average between 33 and 43 % of their total range under future climate, and up to 18 species may lose their climatically suitable range completely. Species whose suitable climate is projected to disappear occur in mountainous regions, particularly isolated ranges such as the Sierra Nevada de Santa Marta. Depending on the representation target considered, between 46 and 96 % of the species evaluated may be adequately represented in protected areas. In the future, the fraction of species potentially adequately represented is projected to decline to 30–95 %. Additional protected areas may help to retain representativeness of protected areas, but monitoring of species projected to have the largest potential declines in range size will be necessary to assess the need of implementing active management strategies to counteract the effects of climate change.     

适应气候变化的认知与政策评价

气候变化已成为不争的事实.减缓和适应是人类应对气候变化的两类主要措施,在气候变化减缓行动难以很快奏效的情形下,采取具有针对性的适应战略已经成为世界各国更为紧迫的选择.一个有效的适应行动机制需要全社会的广泛参与,而公众和决策层对气候变化的认知是适应行动机制的形成基础.本文以银川阅海湿地适应气候变化能力建设为研究案例,从政府部门和社会公众两个层次进行讨论,比较其对气候变化的认知程度及其对适应措施的评价和需求,以期对适应气候变化策略的认知基础研究提供依据.研究结果表明,无论社会公众和决策层,适应气候变化的意识基础均已基本形成,但公众的认知基础要弱于决策层,并且在认知的准确程度上低于决策层;公众和决策层对气候变化适应政策的实施都做出了正面的评价,但决策层的评价普遍显著高于公众;对于适应政策的需求,公众的政策需求主要集中在公共服务方面,而决策层的适应策略是多方位的,也包括通过限制个人行为来获得公共利益.

The Voice of Science on Climate Change in the Mainstream Turkish Press

This study aims to explore how the Turkish press represents the discourse of climate change scientists. This is achieved by analyzing climate change-related articles that quote scientists, directly and indirectly, in two Turkish mainstream newspapers (N = 132, 7 years). The Turkish case illustrates how scientific rhetoric is used for presenting climate change as a matter of concern in an industrializing country. The analysis suggests that climate science is portrayed as an un-discussed authority. News articles rely on data about the disturbance of species and the state of the natural environment to provide proof of global warming, by which they produce an implicit moral imperative. The articles also portray the worst threats and challenges—those pertaining to human society—as residing mostly in the future. We conclude by discussing the implications of the use of a projected future to convey a discourse emphasizing the alarming risks associated with climate change.     

Problems of cross-scale coastal management in Scandinavia

Transdisciplinary knowledge integration and cross-scale management remain challenges in coastal management after several decades of research and experience with integrated and sustainable coastal management. The aim of this paper is to identify requirements for knowledge integration and development of multi-scale approaches to coastal management through reviewing and re-analysing three Swedish-European research projects: the SUCOZOMA project about sustainable coastal zone management, the FRAP project about conflicts between coastal fishery and species protection, and the SECOA project about solutions to contrasts in coastal metropolitan areas. The strategy of adaptive governance is considered in the light of its ability to assess knowledge requirements for sustainable resource management under conditions of climate change.     

Coastal management, climate change adaptation and sustainability in small coastal communities: leatherback turtles and beach loss

Beaches are frequently subjected to erosion and accretion that are influenced by coastal development interventions and natural variations due to storms and changes in river flow. Climate change may also exacerbate beach erosion and accretion. Natural scientists are concerned with the sustainability of species dependent on the beach ecosystem. Policymakers are pre-occupied with the economic sustainability of coastal communities should species decline and prolonged beach loss occur. The aim of this paper is to explore the linkage between science and policy by reporting the findings of a study of coastal change impacts on leatherback turtle nesting and analysing the socio-economic and adaptation implications of these changes for coastal communities. Grande Riviere, Trinidad, was used as a case study. Primary fieldwork investigated unsustainable coastal management practices. A questionnaire was administered to examine livelihoods, including ecotourism based on leatherback turtle nesting, and knowledge and awareness of climate change. One key finding of the study was that the community’s livelihoods were natural resources dependent, and that natural beach dynamics and unsustainable coastal management practices posed major threats to natural resource and economic sustainability. Another key finding was that, despite these impacts, community knowledge and awareness of climate change in general was low, and there was a perception of state responsibility for climate change adaptation. The research findings have global applicability for coastal communities at risk of exposure and that are highly vulnerable to natural resources damage arising from anthropogenic stress and potential climate change. These communities require policy reforms to strengthen current coastal management practices and adaptation responses aimed at ensuring long-term sustainability.     

Whale watch or no watch: the Australian whale watching tourism industry and climate change

Whale watching is a billion dollar industry worldwide. One of the most popular species for whale watching is the humpback whale (Megaptera novaeangliae). The migratory corridors, feeding, resting and calving sites which are used for whale watching may be influenced by changing ocean currents and water temperatures. Here, we used an innovative approach addressing the emerging issue of climate change on the whale watch industry. This involved participatory modelling using key stakeholders for the whale watching industry to develop a systems conceptualisation model for evaluating the potential effects of climate change based on a case study from the east coast of Australia. This participatory approach allowed us to identify the causal linkages (including feedback pathways) between different “Elements” of the system within which the whale watching industry operates. It also allowed us to integrate multiple drivers covering socio-economic and environmental aspects including climate change (e.g. temperature), policy (e.g. number of boats), ecology (e.g. number of whales) and socio-economics (e.g. number of tourists) to evaluate the changes in the overall system. We then developed a Bayesian belief network model from the systems conceptualisation on which stakeholders identified a priority issue (Profitability). Stakeholders provided the structure and the quantification of this model, and a sensitivity analysis was carried out to help identify important intervention points for the industry. Overall, our research illustrates how such a modelling process can assist local tourism operators and authorities in making rational management decisions within a holistic or systems-based framework and its approach is applicable to other regions.
