The Impact

Human economic activity is defined as an anthropogenic process that has a negative impact on natural environment. The urbanisation and agricultural development influence the environment mostly. In order to receive economic benefit to the above-mentioned activities, the landscape is changed, the soil is affected and pollutants are released into the environment. In the light of the fact that the identified processes and problems caused by them are global, the variety of international directives are designed to minimise the impact of anthropogenic activities on the environment. The territory of the Republic of Lithuania has a considerable amount of areas, where the economic activity is suspended, i.e. the land is abandoned. This is due to a variety of social, natural and economic reasons. This process can be perceived as opposite to the anthropogenic activity, however it is important to examine how it affects the environment, landscape or economic needs. These processes are relevant on the local and international level, therefore, the scientific results of this article may be useful for the professionals in various areas and further research. The research investigates the territory of abandoned agricultural land, which is to be urbanised in the future. Land cadastre data, spatial planning documents are analysed, a questionnaire-based survey is conducted, and the actual inspection in the area is carried out. The research results identify the causes for non-use of the land, and the impact of no economic activity on the environment, the landscape and the economic performance. To reach the set objectives, the data analysis, synthesis, induction methods have been used.

Nitrogen Fixing Bacteria

Rhizosphere microbiomes which have been implicated to enhance plant growth and yield are modulated or influenced by a couple of environmental factors such as soil type, plant cultivar, climate change and anthropogenic activities. In particular, anthropogenic activity such as the use of nitrogen-based chemical fertilizers is associated with environmental destruction and this call for a more ecofriendly strategy to increase nitrogen level of agricultural land. This feat is attainable by harnessing nitrogen-fixing endophytic and free-living rhizobacteria. Rhizobium, Pseudomonas, Azospirillum and Bacillus have been found to have positive impacts on crops by enhancing both above and belowground biomass and could therefore play positive roles in achieving sustainable agriculture. Thus, it is needful to study these rhizosphere microbiomes with more sophisticated culture-independent technologies such as next generation sequencing (NGS) with the prospect of discovering novel bacteria with plant growth promoting traits. This review is therefore aimed at discussing factors that can modulate rhizosphere microbiomes with focus on the contributions of nitrogen fixing bacteria towards sustainable agricultural development and the techniques that can be used for their study.

The Impact

Reduced mobility and less anthropogenic activity under special case circumstances over various parts of the world have pronounced effects on air quality. The objective of this study is to investigate the impact of reduced anthropogenic activity on air quality in the mega city of Shanghai, China. Observations from the highly sophisticated multi-axis differential optical absorption spectroscope (MAX-DOAS) instrument were used for nitrogen dioxide (NO2) and formaldehyde (HCHO) column densities. In situ measurements for NO2, ozone (O3), particulate matter (PM2.5) and the air quality index (AQI) were also used. The concentration of trace gases in the atmosphere reduces significantly during annual Spring Festival holidays, whereby mobility is reduced and anthropogenic activities come to a halt. The COVID-19 lockdown during 2020 resulted in a considerable drop in vertical column densities (VCDs) of HCHO and NO2 during lockdown Level-1, which refers to strict lockdown, i.e., strict measures taken to reduce mobility (43% for NO2; 24% for HCHO), and lockdown Level-2, which refers to relaxed lockdown, i.e., when the mobility restrictions were relaxed somehow (20% for NO2; 22% for HCHO), compared with pre-lockdown days, as measured by the MAX-DOAS instrument. However, for 2019, a reduction in VCDs was found only during Level-1 (24% for NO2; 6.62% for HCHO), when the Spring Festival happened. The weekly cycle for NO2 and HCHO depicts no significant effect of weekends on the lockdown. After the start of the Spring Festival, the VCDs of NO2 and HCHO showed a decline for 2019 as well as 2020. Backward trajectories calculated using the Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model indicated more air masses coming from the sea after the Spring Festival for 2019 and 2020, implying that a low pollutant load was carried by them. No impact of anthropogenic activity was found on O3 concentration. The results indicate that the ratio of HCHO to NO2 (RFN) fell in the volatile organic compound (VOC)-limited regime.

AbstractDespite harsh climate, agriculture on the northern margins of Russia still remains the backbone of food security. Historically, in both regions studied in this article – the Republic of Karelia and the Republic of Sakha (Yakutia) – agricultural activities as dairy farming and even cropping were well adapted to local conditions including traditional activities such as horse breeding typical for Yakutia. Using three different sources of information – official statistics, expert interviews, and field observations – allowed us to draw a conclusion that there are both similarities and differences in agricultural development and land use of these two studied regions. The differences arise from agro-climate conditions, settlement history, specialization, and spatial pattern of economy. In both regions, farming is concentrated within the areas with most suitable natural conditions. Yet, even there, agricultural land use is shrinking, especially in Karelia. Both regions are prone to being affected by seasonality, but vary in the degree of its influence. Geographical location plays special role, and weaknesses caused by remoteness to some extent become advantage as in Yakutia. Proximity effect is controversial. In Karelia, impact of neighboring Finland is insignificant compared with the nearby second Russian city – Saint Petersburg.

AbstractThe Republic of Serbia must make significant efforts to promote and exploit renewable energy sources and increase energy efficiency in all energy sectors to ensure energy security and economic competitiveness, reduce the negative impact on the environment from energy production and use, and contribute to global efforts to reduce greenhouse gases. Within the paper several issues of integration of recently realized CHP plant are introduced and discussed. Firstly, the legal and energy policy issues in the Republic of Serbia regarding connecting CHP to the grid are presented. The challenges and technical solutions for CHP connection to the grid, as well as power quality issues and the role of the CHP plant during the restoration of power supply during the maintenance of the substation and unplanned loss of high voltage supply, are presented and discussed. Finally, the impact of prospective massive integration of CHP on the energy balance and CO2 emission reduction in the province of Vojvodina in Serbia is investigated and discussed. Since it is the first CHP plant realized in Serbia, it is crucial that experience be shared to all potential stakeholders in the future energy efficiency projects.

Myeloproliferative neoplasms (MPNs) are associated with a high disease burden, reduced quality of life and shortened survival. The aim of this questionnaire was to gain patients' and caregivers' perspectives on the impact of living with an MPN in the Republic of Ireland. An Irish adaptation of the ‘Global MPN Landmark survey’ was conducted. Fifty-one patients and 44 caregivers completed the questionnaire. Patients reported a wide variety of symptoms at the time of questionnaire completion; fatigue, bone pain and pruritus being most frequently reported. Approximately one-third of respondents from each of the groups (patients and caregivers) reported a negative impact of MPNs on their emotional wellbeing and daily lives. The study findings revealed that, despite treatment, symptom burden remains high, and several unmet needs exist, including educational, emotional and peer group support. Interventions that focus on reducing symptom burden and addressing these unmet needs, may improve the quality of life for patients with MPNs and their caregivers.

The problems in this paper belong to the field of migration and economy. The connection between migration and the economy has been proven on a global level, and as far as the Republic of Croatia is concerned, it is especially important to observe it through the City of Zagreb, which is the most important migration and economic center in the Republic of Croatia. Also, the accession of the Republic of Croatia to the European Union emphasized the observation and research of this connection because it created the preconditions for freer movement and employment of the population of the Republic of Croatia and the City of Zagreb within the European Union. The aim of this paper is to determine the contribution of migration to the economic growth of the City of Zagreb. The hypothesis presented in the paper is that there is a significant contribution of migration to the economic growth of the City of Zagreb. The disposition of the paper consists of six parts. The introduction explains the relevance of the topic, states the aim of the paper and hypotheses, explains the empirical part, the contribution of the paper and the disposition. The second part of the paper refers to the theoretical framework of the impact of migration on economic growth. The third part of the paper presents the migration processes of the City of Zagreb in the period from 2011 to 2018. The fourth part deals with economic activity in the City of Zagreb in the period from 2011 to 2017. The observed indicators of economic activity in the City of Zagreb are GDP and GDP per capita, and the graph in this part of the paper shows that GDP and GDP per capita in the observed period are higher at the end of the period than at the beginning. The fifth part of the paper refers to the empirical research of the contribution of migration to the economic growth of the City of Zagreb. The empirical part of the paper is based on correlations and regression analyses. This paper proves the hypothesis because the results indicate a significant impact of the variables of total and external migration on the GDP of the City of Zagreb and GDP per capita of the City of Zagreb. Decision-makers in the City of Zagreb can use the results of the research as a basis for maximizing the economic benefits they can get from migration. The conclusion provides an overview of the aim of the work, the results of the research, the limitations, the implications and the recommendations for future research.

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.
