Forest fires are one of the most important environmental factors affecting the environment. Due to climate change and the increasing frequency of forest fires, studies of the consequences of forest fires and the processes of restoration of disturbed geosystems are relevant. Over the past 20 years, there has been an increase in the frequency of fires on the territory of the Republic of Buryatia as a whole, and the western macro slope of the Barguzin ridge in particular. The situation is aggravated by the fact that a significant part of the fires occur in hardto- reach areas of the ridge, which complicates their elimination. The paper presents the results of observations (2015-2020 years) on the impact of forest fires on the taiga geosystems of the western macroslope of the Barguzin ridge. The features of post-fire restoration of geosystems are considered. The natural restoration of forests depends on the nature of the forest growing conditions and the ecological characteristics of the stands. Restoration of dark coniferous-taiga geosystems, including relict ones, after intense fires has not been revealed, since forest growing conditions are changing. The relevance of the research is also related to the fact that the western macroslope of the Barguzin Ridge is located within the Baikal Natural Territory (BPT), where protected areas are located and it is not uncommon for fires to disrupt relict geosystems that are under protection.

AbstractCorona virus disease 2019 (COVID-19) has been declared a global pandemic and is a major public health concern worldwide. In this study, we aimed to determine the role of environmental factors, such as climate and air pollutants, in the transmission of COVID-19 in the Republic of Korea. We collected epidemiological and environmental data from two regions of the Republic of Korea, namely Seoul metropolitan region (SMR) and Daegu-Gyeongbuk region (DGR) from February 2020 to July 2020. The data was then analyzed to identify correlations between each environmental factor with confirmed daily COVID-19 cases. Among the various environmental parameters, the duration of sunshine and ozone level were found to positively correlate with COVID-19 cases in both regions. However, the association of temperature variables with COVID-19 transmission revealed contradictory results when comparing the data from SMR and DGR. Moreover, statistical bias may have arisen due to an extensive epidemiological investigation and altered socio-behaviors that occurred in response to a COVID-19 outbreak. Nevertheless, our results suggest that various environmental factors may play a role in COVID-19 transmission.

Cloudiness and range of visibility are the most significant flight conditions for aircraft. The impact of clouds and visibility on the safety of aircraft flights, especially small aircraft, cannot be overestimated. According to the Interstate Air Committee, Kazakhstan ranks second in the number of aviation disasters. The average age of a third of Kazakhstan's small aircraft is more than 30 years. Over the past few years, 14 air accidents have occurred in the Republic of Kazakhstan, 11 of them with small aircraft. In this work, we investigate long-term data on cloudiness and visibility at the most weather-favorable airfield in Balkhash, for the possibility of safe and economical flights of small aircraft and planning training flights.

Introduction. Tourism is a dynamic, constantly developing sector of the economy. Tourism economy develops along with the society, recreation and tourism. The purpose of the article is to show the features of the impact of tourism on the national economy using the case of Tunisia. The experience of Tunisia is especially useful for the countries where beach recreation has developed and where the political situation has remained difficult for a long time (Egypt, Turkey, Thailand, etc.). Materials and Methods. The article is based on the statistical data provided by the World Tourism Organization, the World Data Atlas and open Internet sources. The study employed general scientific methods (analysis, synthesis, synthesis, comparison, etc.) and special ones (the methods of mathematical statistics, the graphical method, the comparative method, etc.). Results. For the first time, the article has provided a fairly complete description of the macroeconomic indicators characterizing the level of development of international tourism in Tunisia. The article has analyzed the dynamics of inbound and outbound tourism, discussed the factors affecting the volume of international tourism, considered international tourism expenditures and revenues, which to a large extent have a positive or negative impact on the country’s balance of payments. The trends in the development of international tourism in Tunisia have been revealed and the problems facing the industry have been identified. Discussion and Conclusion. The research has revealed that tourism economy largely depends on the political and economic processes taking place in the country. The current level of macroeconomic indicators of tourism economy in Tunisia lags behind the 2008–2009 figures. The results of the study made it possible to assess the current state of international tourism and make a number of suggestions aimed at increasing the level of development of international tourism in the country. The results of the study can contribute to the development of a program aimed to boost tourism economy in Tunisia, one of the key tasks of which should be that of increasing performance at the macro-level.

The Impact

The impact of globalization has penetrated throughout the civilization of the nations of the world, running so fast. Especially very influential on changes in various lines of life. Related to this is the issue of increasing narcotics abuse and narcotics illicit trafficking which has created conditions that have hindered the development process and weakened civilization. Eradication of narcotics distribution is a national problem, because it has a negative impact that can damage and threaten the lives of the people, nation and state and can hamper the national development process. The rise of narcotics abuse does not only occur in big cities, but has reached small cities in all ten regions of the Republic of Indonesia, including East Aceh Regency. The increasingly diverse lifestyle of the people due to the influence of globalization also contributes to the increasing circulation of narcotics in East Aceh District. This certainly must receive serious attention, because if we look at what is happening in East Aceh District and several other regions in Indonesia, the crime of narcotics distribution from time to time always increases which in the end is increasingly unsettling the community, so before these things increase In East Aceh District, an effective solution must be found to eradicate it. Factors that cause a person to commit a narcotics crime in East Aceh Regency are due to economic factors where a person needs money to live and the difficulty of getting work, family environmental factors, social environmental factors and availability / lack of supervision factors. Efforts in tackling narcotics circulation in East Aceh district involve many parties, including: firstly, pre-emptive efforts by providing counseling in the community and schools about narcotics carried out by the police in tackling narcotics crime in East Aceh District. Second, preventive measures (prevention) by conducting raids and patrols routinely, providing oversight of the association and positive activities carried out by the police, prosecutors, religious leaders, community leaders and youth organizations. The third repressive effort (action) which aims to provide a deterrent effect on the perpetrators of drug trafficking crimes involving all law enforcement officials ranging from the Police, Attorney and District Courts and Detention Houses.Keywords: Crimonology, Narcotics Circulation.

Abstract. The target of this work was to assess the impact of projected climate change on forest-fire activity in Finland with special emphasis on large-scale fires. In addition, we were particularly interested to examine the inter-model variability of the projected change of fire danger. For this purpose, we utilized fire statistics covering the period 1996–2014 and consisting of almost 20 000 forest fires, as well as daily meteorological data from five global climate models under representative concentration pathway RCP4.5 and RCP8.5 scenarios. The model data were statistically downscaled onto a high-resolution grid using the quantile-mapping method before performing the analysis. In examining the relationship between weather and fire danger, we applied the Canadian fire weather index (FWI) system. Our results suggest that the number of large forest fires may double or even triple during the present century. This would increase the risk that some of the fires could develop into real conflagrations which have become almost extinct in Finland due to active and efficient fire suppression. However, the results reveal substantial inter-model variability in the rate of the projected increase of forest-fire danger, emphasizing the large uncertainty related to the climate change signal in fire activity. We moreover showed that the majority of large fires in Finland occur within a relatively short period in May and June due to human activities and that FWI correlates poorer with the fire activity during this time of year than later in summer when lightning is a more important cause of fires.

The Impact

This paper examines the impact that climate change may have on the lodging of oats in the Republic of Ireland and the UK. Through the consideration of a novel lodging model representing the motion of an oat plant due to the interaction of wind and rain and integrating future predictions of wind and rainfall due to climate change, appropriate conclusions have been made. In order to provide meteorological data for the lodging model, wind and rainfall inputs are analysed using 30 years’ time series corresponding to peak lodging months (June and July) from 38 meteorological stations in the United Kingdom and the Irish Republic, which enables the relevant probability density functions (PDFs) to be established. Moreover, climate data for the next six decades in the British Isles produced by UK climate change projections (UKCP18) are analysed, and future wind and rainfall PDFs are obtained. It is observed that the predicted changes likely to occur during the key growing period (June to July) in the next 30 years are in keeping with variations, which can occur due to different husbandry treatments/plant varieties. In addition, the utility of a double exponential function for representing the rainfall probability has been observed with appropriate values for the constants given.

Abstract Carbon allocation plays a key role in ecosystem dynamics and plant adaptation to changing environmental conditions. Hence, proper description of this process in vegetation models is crucial for the simulations of the impact of climate change on carbon cycling in forests. Here we review how carbon allocation modelling is currently implemented in 31 contrasting models to identify the main gaps compared with our theoretical and empirical understanding of carbon allocation. A hybrid approach based on combining several principles and/or types of carbon allocation modelling prevailed in the examined models, while physiologically more sophisticated approaches were used less often than empirical ones. The analysis revealed that, although the number of carbon allocation studies over the past 10 years has substantially increased, some background processes are still insufficiently understood and some issues in models are frequently poorly represented, oversimplified or even omitted. Hence, current challenges for carbon allocation modelling in forest ecosystems are (i) to overcome remaining limits in process understanding, particularly regarding the impact of disturbances on carbon allocation, accumulation and utilization of nonstructural carbohydrates, and carbon use by symbionts, and (ii) to implement existing knowledge of carbon allocation into defence, regeneration and improved resource uptake in order to better account for changing environmental conditions.
