In the present study, the defoliation status of spruce stands is related to mycorrhizal conditions and presence of mycorrhizal macromycetes fungi in two localities at the highest sites of the Krkonoše Mts. In the long-term view, the defoliation and the diversity of mycorrhizal fungi have improved but the number of active as well as nonactive mycorrhizae has decreased while their ratio has not changed. Statistically significant is the correlation between the total number of mycorrhizae and pH. The results within last years of observations as well as in comparison to the conditions in the last decade show that mountain spruce stands growing at non-exposed sites are tolerant to a degradation of mycorrhizal conditions resulting from the long-term air pollution impact. The studied parameters of mycorrhizal symbiosis have not shown a clear trend; their results however indicate the stabilized mycorrhizal state. Positive changes can be seen in the total increase of macromycetes diversity as well as in the apparent increase of percentage of macromycetes in the studied localities, which correlates to the moderately improving defoliation.

The cult of Triglav in the Polabian-Pomeranian territory in the 12th century confirms an evolution of the religious system of the local Slavic communities towards monolatry, largely affected by confrontation as well as a cultural dialogue with the Christian culture. At first, at the time of the Pomeranian missions of Saint Otto of Bamberg in the 1120s, attempts at suppressing the cult did not bring about long-term effects. However, a wave of the so-called pagan reaction led to some sort of a compromise made in Szczecin, leading to official coexistence of the cult of Triglav and the newly introduced cult of Jesus Christ. From the point of view of mythology, the competences of the two divine figures turn out to be convergent and universal, yet still, as part of the Szczecin “religious dualism”, no attempt was made to identify them (following the rule of interpretatio Slavica of the elements of Christianity). The belief in the autonomy of Triglav and Christ (“A German God”) was confirmed in Szczecin in the course of Otto’s evangelization which resulted in a Christian community in the city. The phenomenon of syncretism, present there until Otto’s second mission (1128), was therefore an attempt at maintaining unity in a religiously divided society following the first mission of the Apostle of Pomeranians (1124-1125).

ic health requires processing large amounts of data from long-term research, which necessitates the use of modern geoinformation technologies. Geoinformation technologies are a mechanism for assessing environmental risks to public health in conditions of man-made air pollution in cities. The results obtained in the course of long-term monitoring studies are summarized in the GIS environment “Environmental and socio-economic conditions of cities in Central Russia”. The collection of information to characterize the functional and planning structure and landscape and environmental conditions for the model regions was carried out on the basis of special field research, processing of stock, including cartographic, material of regional integrated and sectoral environmental agencies. Currently, Russia and the world have different approaches to assessing the environmental risk for the population living in industrial cities. In Russia, the methodology of the center for hygiene is most widely used. Erisman, as well as the methodology for assessing environmental risk developed by Professor V. Prevalence. Of studies environmental and social conditions in the city of Voronezh, conducted by researchers of Voronezh state University under the direction of Professor S.A. Kurolap collected in electronic health-environmental GIS-Atlas of the city of Voronezh. The Atlas contains maps showing the state of the environment, public health, and environmental risks in various parts of the city of Voronezh. Currently, various researchers have proposed a number of methodologies for geoinformation assessment of environmental safety of the population of large cities. At the same time, there is no unified approach to assessing environmental comfort that covers its various components, which makes it advisable to develop an integrated methodology based on the data available to us.

Vertical farming is a technological farming method that allows to grow crops without the need for large fields, soil and climatic cycles as in traditional agriculture. This method is becoming increasingly important due to the fact that water, pesticides, fertilizers, labor, equipment, energy and transportation costs are low, efficiency and quality are high, livestock can be carried out simultaneously, it improves the architecture and air of the city, and it will increase the interest and contribution of the city people to agriculture. Since it is predicted that the world population will be 10 billion in 2050, the ecological balance will deteriorate further and fertile land areas will rapidly decrease due to global warming, many countries have started to actively apply this agricultural method. Although the initial investment costs are high, this agricultural practice, which has high sustainability in terms of its contribution to the economy, ecology and social integration in the long term, will be the most important agricultural industry of the future. For this method, which is important in terms of sustainable agriculture, arrangements should be made in state policies and legal issues, financial resources should be allocated in our country, and the participation of academics, private sector, municipalities, farmers and urban society in the process should be ensured.

A necessary and effective coordination between cadastre and land registry has always existed in Spain, but the difficulties have only been specifically addressed in the last few years. The aim of this study is to illustrate, analyse, and evaluate advances in this coordination in Spain from the beginnings of the current system in the early twentieth century, with the cadastre and land registry operating as separate organisations. A preliminary study was made in 2002 of the difficulties that needed to be overcome to achieve an ideal coordination of mainly mapped information. The study was made by gathering and analysing the opinions of various specialists who have dealt with the issue of coordination. For this research, qualitative information (current and historical) was gathered by querying documents about cadastre and land registry coordination in Spain. This information was studied and compared to identify the problems and challenges. A survey in 2012 analysed the relationship between the cadastre and land registry from the point of view of the general public in the city of Gandia. The Spanish government enacted the first specific and effective legislation on coordination in 2015 (Act 13/2015), and much has changed since its introduction. During the last five years of application, each of the problems initially highlighted has been monitored and analysed, and the difficulties that have arisen have been noted. In this study, each of these problems and challenges is analysed from various perspectives: querying documents (norms, budgets, official news, etc.), websites, digital applications, observation, and interviews. The main results of the case study in Spain are as follows: coordination is generally indispensable and cannot be postponed; there is a difficult understanding between the organisations involved; the general public associate the word “cadastre” with taxes and not with security in the demarcation of property; political will and understanding is necessary; the process is slow and requires long-term agreements; an improvement in the quality of maps is fundamental; and technology is not a problem.

The work presents the analysis of air pollution in the City of Odesa using, among others, the data of automated observations. The air basin state was also evaluated using individual parameters of sustainable development. According to the official data of the recent years the City of Odesa belongs to the most polluted cities of Ukraine in terms of air pollution. Based on the ranking results it was established that the level of atmospheric pollution in the City of Odesa can be classified as high for the most of pollutants. It is classified as acceptable for some substances (sulfur dioxide and nitrogen oxide) and as extremely high for formaldehyde concentration. After comparing the observational data related to content of individual pollutants at the OSENU's observation point and the data of long-term observations in the city it was found that the content of nitrogen dioxide generally corresponds to the average long-term values. The observations conducted at the points of the city network indicated that the content of carbon monoxide is two orders of magnitude lower and the content of PM10 is one order of magnitude lower than dust concentrations. The increased content of certain pollutants in the air (nitrogen dioxide, carbon monoxide, etc.) is observed in the summer-autumn period and caused by the traffic intensification. The evaluation of the city's air basin state using individual parameters of the environmental measurement index showed that we observed better conditions in 2014 and 2016. The conditions for sustainable development are characterized by average indicators, however, towards worsening of the situation. The results obtained in this paper form a basis for extending the implementation of the Resolution of the Cabinet of Ministers of Ukraine on introducing a new procedure for state monitoring of the atmospheric air in Ukraine. The existing laboratory base of the observation points requires radical re-equipment. It is also necessary to conduct an air pollution survey for identification of high priority pollutants and, based thereon, development of monitoring programs with consideration of the necessity for keeping certain impurities under control.

Introduction. Air pollution with particulate matter (PM) is a serious global problem. In the Russian Federation, regular field measurements of PMs in the ambient air are carried out only in a few cities, and the data, as a rule, are not systematized. Aim of the study: long-term analysis of the data set on concentrations of fine particles in the ambient air of the city of Kazan. Material and methods. Long-term analysis of ambient air pollution by fine particles in the city of Kazan for the period from 2016 to 2020 has been carried out. To study the effect of separate factors (year, measurement time during the day, climatic conditions, the presence of other pollutants) on the levels of PM10 and PM2.5, regression analysis was applied based on the method of mixed models. To characterize the elemental composition of the PM2.5 fraction, sampling of atmospheric air on PVC filters was carried out by use of 100 NR impactor (TSI, USA). The step function and MPPD model were applied to calculate the number of particles and the mass of the deposited fraction of fine particulate matter in different regions of the human respiratory tract. Results. The PM10 concentrations remained stable over a 5-year period, while the PM2.5 concentrations decreased. At the same time, an increase in the maximum annual concentrations of both fractions was observed. The concentrations of PM10 and PM2.5 significantly depended on climatic conditions. The presence of nitrogen oxides and organic carbon in the ambient air was significantly associated with higher concentrations of PM10 and PM2.5. The elemental composition of PM2.5 fraction was represented mainly by carbon (C) (from 86.16% to 93.45%). Mathematical modeling has shown that PM10 is mainly deposited in the upper respiratory tract, and their presence in the tracheobronchial and alveolar zones is insignificant. PM2.5 particles reach the lower respiratory tract and alveolar area. Conclusion. A statistically significant upward long-term trend in the maximum annual ambient concentrations for both fractions of fine particles can increase health risks. Secondary pollutants (nitrogen oxides, organic carbon) are important factors for the formation of secondary particles in the ambient air. The results obtained indicate that when assessing the risks to public health, it is necessary not only to use the concentrations of fine particles in ambient air, but also to consider the degree of deposition of separate fractions in different parts of the human respiratory tract, considering the alleged pathogenesis and priority target cells characteristic of individual diseases.
