Megjegyzések:	Globally, countries are legitimizing actions to curtail the malevolent impacts of environmental degradation. This study examined the interaction between CO2 emissions and selected economic variables within the framework of Saudi Arabia's Vision 2030. The Autoregressive distributed lag model (ARDL) was used to analyze the long-run relationships and short-run dynamics between studied variables (1970-2020). The Mann-Kendall (MK) test revealed a significant (p < 0.05) positive increase of GHGs emissions from all sectors across the KSA. The highest increased were captured at the electricity and heat by 7345454.47 tonnes of carbon dioxide-equivalents/year (p < 0.05). On the hand, the ARDL model indicates that GDP, agriculture, industry, services, and oil production have short-term effects on the environment through CO2 emissions. Therefore, GDP, agriculture, services and oil production contribute to increases in CO2 emissions. While industry contributes to decrease in CO2 emissions. The ARDL model also showed that an increase in GDP of 1 percent increases CO2 emissions by 3.46 percent, while an increase in oil production of 1 percent increases CO2 emissions by 4.04 percent. However, an increase in industry of 1 percent decreases CO2 emissions by 7.25 percent. The output of this research has a policy implication for addressing environmental concerns in the country.

Cím:	The green light for air transport: sustainable aviation at present / Zsolt Bagdi, Loránd Csámer, Gábor Bakó
Dátum:	2023
ISSN:	2939-5240
Megjegyzések:	In the nearly 120 years of aviation history, the industry and technology have evolved with the world. In the early decades, the focus was on preparing aircraft for passenger transport, and gradually the industry developed different areas such as airports, navigation, in-flight services and air traffic control. The aviation industry has faced quite many challenges in different periods. At the beginning of the JET era, the first very controversial factor, noise pollution, was already apparent. The gas turbines of the time were much less efficient than today`, and although the technology worked, some factors were less considered by developers, such as the noise and environmental impact mentioned above. As we moved into more modern times, the focus shifted more and more to the pollutants emitted by aircraft, which has become one of the most studied factors to date. This research examines the sustainability of aviation, past, present and future, in the light of global warming. It presents technologies that already work in the present, but their possible spread only points to the near or even distant future.

Cím:	Land Use Changes in Peri-Urban Open Spaces of Small Towns in Eastern Hungary / Péter Csorba, Krisztina Bánóczki, Zoltán Túri
Dátum:	2022
ISSN:	2071-1050
Megjegyzések:	Changes in land use were studied in 2 km wide peri-urban open spaces of seven small Hungarian towns as part of a RENATUR Interreg Europe (2019-2023) project. The aim of the project is to present best practices related to the sustainable and wise use of the peri-urban open spaces of small European towns. The rate and tendencies of conversion from one land use type to another were evaluated on the basis of a comparison of Corine Land Cover and Land Cover Change databases from 1990, 2000 and 2018. Land use changes in the study areas in different time periods were studied for which the Corine categories were aggregated. Subsequently, there were field verification surveys carried out between March and June of 2021. Most significant changes?due to the significant increase of built-up areas?were found in the case of the towns that were developed to form the suburbs of Debrecen, the core settlement of their region with a population of 200,000. In the case of settlements further away from the major city, the population is either stagnating or decreasing, and the size of built-up areas hardly increases. In the case of cities that are surrounded by high-quality chernozem soils with profitable agriculture, large-scale arable lands have become dominant in the border zones of the settlements, as the spatial extent of gardens, orchards and grasslands has decreased. Highly diverse and mosaic land use (dominated by small plots) is not characteristic anywhere.

Cím:	The Comprehensive Analysis of the Network of Superstructure Based on Territorial Characteristics of Accommodation and Food and Beverage Service Providers Considering the Financial Crisis and COVID-19: The Case of Bihor County, Romania / Krisztina Czuczor, Gábor Kozma, Zoltán Dorogi, Tianyi Li, Zsolt Radics
Dátum:	2023
ISSN:	2071-1050
Megjegyzések:	This study presents the territorial differences in structure of functioning accommodation and food-and-beverage service providers by their distribution based on registered field of economic activity and financial data on the level of local governments within Bihor County that were classified into four potential destination types. Furthermore, the aim of the research is to identify the concentration of business activities based on their turnover in proportion to the population on the level of local governments using the Hoover-index method for the period of 2005?2020. Lastly, another aim is to examine the efficiency of these hospitality service providers using the Hoover index on their sales revenue in proportion to their labor force between 2005 and 2020. The time frame enabled the examination of the effects of two critical incidents: the financial crisis of 2008 and COVID-19, which impacted the activity of the examined firms in hospitality. As a result, both group of service providers showed a significant increase in number of entities, turnover, and average annual number of employees after 2014. That trend was intensively interrupted by COVID-19, which was not the case for the period of financial crisis. The significance of Oradea and S©anmartin were present as central areas regarding business activities of the examined fields, thus crucially influencing the trends of the county. In the case of territorial inequalities, the two categories showed differing trends, as in the case of efficiency, although lodging services proved to show higher territorial inequalities but better performance.

Cím:	Safety in Public Open Green Spaces in Fortaleza, Brazil : a Data Analysis / Bárbara Mylena Delgado da Silva, Eszter Karlócainé Bakay, Mariana Batista de Morais
Dátum:	2024
ISSN:	2071-1050
Megjegyzések:	Latin America is as heterogeneous as its cities. To understand Latin American cities, it is necessary to have a clear vision of how they are organized, not only physically but according to their social, cultural, and economic contexts (which are associated). Historically, it has suffered a lot in terms of politics and the security of its cities. Insecurity reflects a structural problem; economic and social inequality are the main actors of spatial segregation, motivating violence and, consequently, the insecurity of urban space. Fortaleza is one of the largest Brazilian cities, and it is possible to fit it into this reality. Many public actions may benefit only one sector of society, showing biased investments and, again, confirming the tremendous economic and social differences in Latin American cities. In this study, questionnaires related to attendance, feelings, maintenance, and safety were made to some of Fortaleza's residents regarding an urban park called Parque do Cocó, one of the biggest in Latin America. Due to its large area, it is located in different city neighborhoods, allowing for us to see the differences in treatments throughout its extension. This article aims to understand how the public opinions and mentality of a portion of the population are characterized concerning safety in green public spaces in the city. In addition, the insecurity of public green spaces can also be inserted into a problem of environmental injustice in the urban context. This study of Fortaleza's Cocó Park highlights significant disparities in safety perceptions and maintenance across socioeconomic regions. Findings indicate that areas with higher human development index (HDI) scores experience better park conditions. The research underscores the necessity for comprehensive urban policies that address socioeconomic inequalities, as evidenced by the correlation between crime rates and HDI. Cocó Park emerges as a key factor in sustainable urban development, aligning with Fortaleza's urban planning goals. The study emphasizes the critical role of urban green spaces in enhancing the quality of life and fostering social cohesion in urban landscapes. Moreover, with the data collected, it will be possible to stress further how urban adequacy relates to social situations in Latin American cities.

Cím:	Bayesian model averaging approach to predict future rainfall erosivity in the Gumara-Maksegnit watershed, Ethiopia / Legese Abebaw Getu, Szegedi Sándor, Túri Zoltán, Hailu Kendie Addis
Dátum:	2025
ISSN:	2665-9727
Megjegyzések:	The increasing impact of climate change on rainfall patterns and intensities necessitates robust methodologies to predict rainfall erosivity, a critical factor in soil erosion and hydrology. This study focuses on the Gumara-Maksegnit watershed in the Ethiopian highlands, a region highly vulnerable to soil erosion due to intense rainfall, rugged topography, and limited weather stations. Employing Bayesian Model Averaging (BMA), we predicted rainfall and rainfall erosivity under the RCP 4.5 and RCP 8.5 scenarios, addressing data limitations and improving prediction accuracy. Using historical rainfall data from 1971 to 2005 for calibration and validation, the study ensembled outputs from five Regional Climate Models (RCMs). Monthly rainfall predictions revealed that the BMA technique outperformed individual RCMs in capturing observed rainfall trends. BMA achieved an R2 of 0.69?0.85 for monthly predictions, compared to 0.35?0.75 for individual RCMs, with reduced biases. The analysis indicates that projected rainfall is expected to surpass observed values by 12.5 % and 20 % under the RCP 4.5 and RCP 8.5 scenarios, respectively, with the peak months (July and August) experiencing the most significant increases. Rainfall erosivity is projected to rise by 12 % under RCP 4.5 and 22 % under RCP 8.5, with maximum value exceeding 900 MJ mm ha?1 h?1 yr?1. The study demonstrates the effectiveness of the BMA technique in improving prediction accuracy, particularly in data-scarce regions. Incorporating geographic factors such as topography and altitude and integrating machine learning with BMA may improve its ability to capture extreme rainfall events, which were not explicitly evaluated in this study.

Cím:	Characteristics of Climate Concern : Attitudes and Personal Actions : A Case Study of Hungarian Settlements / Emőke Kiss, Dániel Balla, András Donát Kovács
Dátum:	2022
ISSN:	2071-1050
Megjegyzések:	This article discusses one of the most important social factors of climate protection: climate concern. Most research in this area focuses on North America and Western Europe or presents international comparative statistics. Our work is innovative because we have designated a lesser-known post-socialist region in East-Central Europe as a sample area, and we intend to conduct in-depth analyses at the municipal level. Our study describes the second largest city in Hungary, Debrecen, and its agglomeration. Based on a questionnaire survey in 2020 (N = 512), we examined opinion factors, and we have presented features consistent with or different from the findings in the relevant literature. In the statistical analysis, chi-square tests and binary logistic regressions were applied to reveal significant differences between the responses of different types of respondents. As response variables, we used the questions about general concerns regarding air pollution, knowledge about climate change, beliefs about tackling, perceived threat, behavioural responses, personal actions, and demography. We found that the concern about air pollution and a feeling of threat to respondents' life was mainly affected by the degree of climate concern. We conclude that the knowledge of local communities on climate change has increased, and risk perception has improved. Still, there is no clear relationship between the level of concern and climate-conscious behaviour. The findings provide ideas for promoting local climate management and awareness-raising in the European Union or other countries.

Cím:	Effects of Using Green Concrete Materials on the CO2 Emissions of the Residential Building Sector in Egypt / Heba Marey, Gábor Kozma, György Szabó
Dátum:	2022
ISSN:	2071-1050
Megjegyzések:	Increasing the rate of construction material consumption has caused significant environmental problems in recent decades, especially the production of ordinary Portland cement (OPC), which has been associated with 8% of the world's human CO2 emissions and is considered the leading binder of concrete. This study aims to investigate the effects of substituting conventional concrete (CC) material with green concrete (GC) in the non-structural concrete works of a residential building in New Borg El-Arab City, Egypt. It attempts to establish what the effects are of using GC on cement, natural aggregates, and CO2 emissions in the design phase. By using a design-based solution (DBS), we began with redesign, reduce, reselect, reuse, and recycle strategies to find an optimal solution for applying recycle aggregate concrete (RAC) as a replacement material in selected building parts, such as the internal floor, external sidewalk, entrance steps, and wall boundary. AutoCAD software and 3Dmax were used to modify the original design and obtain two design references with four different scenarios. Comparative analyses were applied to investigate the effects of different concrete materials. The results show a reduction of about 19.4% in cement consumption in terms of the total concrete of the building and a 44.5% reduction in CO2 emissions due to the reduction of cement in specific building parts. In addition, this solution decreased natural coarse aggregate (NCA) consumption by 23.7% in the final concrete. This study recommends that GC materials close the loop of cementitious material consumption to reduce environmental impacts and achieve sustainability in the Egyptian building sector.
