Respiratory infectious diseases are highly influenced by climate and feature seasonality, whose peak is December to February in the Northern Hemisphere. SARS-CoV-2 produced consistent debate regarding the relationship between its emergence and weather conditions. Our study explored these conditions, expressed by three main parameters-ultraviolet radiation, air temperature and relative humidity-that characterized Hubei (China), the source region of COVID-19 pandemic, in November 2019-March 2020. During COVID-19 outbreak, the low amounts of UV radiation (down to-273 kJ m-2 in January 2020) were associated with the early stage environmental survival of the novel coronavirus. As well, this period was characterized by a high relative humidity during peak hours of the day, and a positive air temperature anomaly (+1.7°C in December 2019), which also favored the outdoor people mobility in winter. Based on Hubei analysis, a presumed optimal weather frame was set in order to identify other world regions with similar weather characteristics. In brief, the "Hubei weather profile" was recorded in those regions of COVID-19 outbreak in February 2020, such as northern Iran, Italy or Spain. Our results, which focused on the role of the UV solar radiation, could be used as a prediction tool for identifying the world regions with a higher risk of future faster increase in COVID-19 cases.
The potential role of tourism in enhancing a balanced territorial development is officially acknowledged by the EU. However, little is known regarding the extent to which tourism in Romania contributes or could contribute to reducing regional inequalities. The present study approaches the matter of the growth of tourism demand and supply in relation to the type of territory (lagging, intermediary, leading), at both regional and local levels. The results indicate a significant geographical concentration of tourism activity, despite a noticeable diffusion of tourism across the country in the last decades. This derives from the fact that the leading territories, which already took the lion's share of the tourism supply and demand also retain the highest part of the increases in tourism demand. As a consequence, tourism sector stands out more as a factor that can increase territorial disparities than contribute to their reduction. However, a considerable potential for tourism growth in terms of tourism supply characterizes the lagging regions. Accordingly, differentiated tourism public policies related to the type of territory could be considered.
Lake (or lacustrine) water is one of the most sensitive and vulnerable resources for many tourist destinations, whose attractiveness highly depends on the water quality and availability in the lakes. The Shchuchinsk-Burabay resort area, located in the Akmola region of the Northern Kazakhstan, is one of the most popular tourist destinations of the country, known for its attractive natural landscape and for its great number of lakes. However, during the last decades, these lakes have been facing environmental issues due to their overexploitation and increasing level of pollution. Thus, the aim of the current study is to examine the changes in surface area of these lakes during the last 30 years by using GIS technologies, and the influence of tourism industry upon this phenomenon. Accommodation facilities (hotels, sanatoriums and guesthouses), as main tourism-related water consumers, have been targeted within our analysis. Results show that tourism is one of the factors responsible for surface area decline of the main lakes in the region, and its responsibility increases when combined with other factors. This study also formulates recommendations for water management policymakers in order to guarantee the sustainability of lake water as a key resource of the tourism industry in the region.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
