Collection and Monitoring Cross-National Urban Mobility Data – Issues, Limitations and Perspectives
No full textOne of the key challenges in analyzing urban mobility, especially on a cross-national scale, lies
in the collection of high-quality and methodologically comparable data. This includes not only
transport data but also spatial, socio-economic, and environmental data necessary for a
comprehensive analysis. Comparable urban and transport data for different cities around the world
and across different time periods are rarely available. Since the pioneering work of Newman and
Kenworthy, there have been few attempts to create such a database. The main reasons for this are
inconsistent data collection methods, a lack of primary data, ambiguity in different indicators, and
varied definitions of metrics, among others. These challenges hinder the creation of a
comprehensive understanding of urban mobility, making it difficult to assess the impact of existing
policies and interventions. The problems arising from these issues include difficulties in developing
accurate and effective policy recommendations, identifying best practices, and evaluating
sustainability progress, as well as challenges in forecasting future mobility trends. This is
particularly evident in developing metropolises, which are experiencing the greatest demographic
growth, the highest urbanization rates and improvements in living standards—factors that
contribute to significant and urgent urban mobility challenges. This study aims to examine the
issues and limitations associated with cross-national urban mobility data collection and propose
strategies for improving data harmonization, methodological consistency, and the integration of
modern technologies such as big data analytics, IoT, and GIS. By addressing these challenges, the
study seeks to contribute to the development of a standardized framework that enhances global
urban mobility data collection, enabling policymakers to make informed decisions that support
sustainable urban development.Editor: Mladen Šoški
Methodological Advances in Participatory Processes in Serbia: Enhancing Spatial Planning and Living Environments in Mining Regions
No full textParticipatory processes play a crucial role in spatial planning, particularly in mining regions where environmental and social impacts of resource extraction are significant. This research examines the need to adapt and improve public participation procedures in Serbia, emphasizing the legal framework, methodological enhancements, and institutional support to foster more meaningful engagement of the affected population. Conducted under the funding of the Science Fund of the Republic of Serbia (Grant #7598), the study is based on in-depth interviews with key stakeholders responsible for shaping participation processes in legislation, education, and practice. The research identifies challenges in existing participatory mechanisms and proposes solutions to enhance their effectiveness. A key recommendation is the enrichment of participatory methods at the earliest stages of planning—before formal decisions on plan creation are made—by improving stakeholder information, education, and early engagement. The study also highlights the importance of maintaining continuous feedback loops with stakeholders throughout the planning process and considering public participation during the spatial plan implementation phase. Furthermore, restoring trust in national and local government, as well as other decision-makers, is recognized as a critical factor in ensuring meaningful public participation. Strengthening institutional commitment to transparency, accountability, and inclusivity is essential for fostering long-term stakeholder engagement and improving decision-making processes in spatial planning. This study contributes to the discourse on participatory governance by advocating for a more legally structured, methodologically enriched, and trust-centered approach to public participation in spatial planning, particularly in mining regions and their living environments.Editor: Natalija Miri

Impact Of Coal-Based Electricity Generation, Land Use Change, Steel And Cement Production On CO2 Emissions: Evidence From Eastern European And Central Asian Countries
No full textThe problem of studying carbon footprint factors is one of the key ones for understanding the relationship between socio-economic development and atmospheric pollution. We employ a panel quantile regression approach to reveal the impact of the energy sector (namely, coal-based electricity and hydropower generation), manufacturing (steel and cement production), and agriculture (cropland area change) on CO2 emissions in 16 Eastern European and 4 Central Asian countries for the period from 2000 to 2020. We provide evidence for a U-shaped environmental Kuznets curve for countries with a lower carbon footprint, while the countries with the highest emissions are found to have an inverted U-shaped relationship between them and GDP per capita. The relationship between electricity production from coal and emissions is positive and significant at all quantiles (except the 30th quantile), and for hydropower, it is negative and significant from the 20th to 70th quantile: a 1% increase in generation leads to CO2 emissions increase by 0.08-0.20% and a decrease by 0.04-0.07%, respectively. Crude steel production positively influences emissions (from the 10th to 80th quantile levels): a 1% increase in the output of steel products results in carbon emissions increase by 0.05-0.07%. The relationship between cropland expansion and emissions is positive from the 40th quantile, but the coefficient shows high significance only at the 80th quantile. These findings allow us to conclude that CO2 emissions reduction in Eastern European and Central Asian countries could be achieved by the replacement of coal in the electricity generation structure by renewables (including hydropower), the introduction of sustainable land use practices to preserve carbon sinks, and technological modernization of crude steel production
Teachers’ attitudes toward the implementation of environmental content in geography education with the aim of fostering environmentally responsible citizens of the 21st century
No full textThe development of science and technology has facilitated human life, but it has also enabled an increasing pressure on the environment. Intensified anthropogenic impact predominantly exerts negative effects on the natural environment, resulting in an ecological crisis. Current demographic and economic processes, such as demographic booms in economically underdeveloped countries, excessive resource exploitation, and others, further aggravate the existing crisis. Consequently, addressing this issue is considered one of the priorities of contemporary humanity. A change in human attitudes toward nature emerges as a key solution to the problem, with adequate environmental education being of paramount importance in this regard. Geography, as an interdisciplinary “bridge science,” provides valuable insight into the interdependence of humans and nature. Owing to its contribution to the development of students’ environmental awareness, geography occupies a prominent place in the environmental education of young people. Given the importance of fostering ecological awareness among students, this research focused on identifying the possibilities for implementing environmental content in geography education. For this purpose, teachers’ attitudes were examined with respect to the relevance and representation of existing environmental content, ecological goals and tasks within curricula, syllabi, and textbooks, as well as their views on the importance of environmental education itself. A questionnaire employing a five-point Likert scale was completed by 100 geography teachers in Serbia. The results were analyzed using statistical, descriptive, and causal methods. The findings revealed that: most teachers are dissatisfied with the extent to which environmental content is represented in geography curricula; a majority of teachers expressed satisfaction or neutrality concerning the quality of ecological goals and tasks present in existing geography teaching programs; most teachers are dissatisfied with the quality of geography textbooks regarding their contribution to achieving the aims and tasks of environmental education; and most teachers lack an adequate level of awareness of the significance of environmental education for students. Finally, the identified teacher attitudes served as the basis for formulating concrete measures aimed at improving the implementation of environmental content in geography education and fostering the development of ecological awareness essential for addressing the ecological crisis of the 21st century.Editor: Natalija Miri
Assessing Biogas Production Potential from Organic Waste and Livestock Byproducts in a Serbian Municipality: Implications for Sustainable Food Systems
No full textIn the process of biogas production, various types of substrates with suitable energy potential are utilized to generate biogas in plants designed for cogeneration (CHP) of electricity and heat. This paper presents a literature review focused on different substrates involved in biogas production, emphasizing their optimization potential. Data for this research were gathered through a comprehensive review of scientific and scholarly literature from global databases. The study examines the biogas production capabilities of various feedstocks employed in cogeneration plants, highlighting the energy potential of substrates, including livestock byproducts such as liquid and solid manure, energy crops, organic waste from the food and slaughterhouse industries, as well as municipal wastewater and solid organic waste. Furthermore, we conducted a practical case study in the municipality of Čačak, which provides valuable insights into effective practices and strategies that can be broadly applied to enhance biogas production in similar contexts. The findings reveal significant variations in biogas production potential among different substrates, emphasizing the importance of strategic selection and management practices. This study contributes to the field by providing a clearer understanding of the substrate optimization process and practical insights that can inform the development of more effective biogas production strategies in local municipalities

Statistički model za procenu količina i potencijala otpada iz domaćinstava u Srbiji u funkciji ponovne upotrebe - ka održivom upravljanju otpadom u kontekstu Zelene agende
No full textCilj rada je da stručnoj i naučnoj zajednici predstavi predlog Statističkog modela za određivanje količina i potencijala otpada iz domaćinstva u funkciji ponovne upotrebe. Povod za razvoj statističkog modela proistekao je iz višegodišnjeg iskustva i rada u oblasti upravljanja otpadom, operativnoj organizaciji i planiranja razvoja sistema upravljanja. Model može poslužiti kao jedan od alata i instrumenata za rešavanje dugogodišnjeg problema u oblasti upravljanja otpadom u Republici Srbiji, a to su nerealni i nepouzdani podaci o količinama i vrsti opada koje se generišu u domaćinstvima, kako i sama Agencija za zaštitu životne sredine (SEPA) ističe u svojim godišnjim izveštajima. Obzirom da je potpuno jasna potreba da se izvrši optimizacija poslovanja JKP i drugih operatera koji se bave upravljanjem čvrstim komunalnim otpadom, nastao i je i imperativni cilj kreiranja statističkog modela koji treba da pruži što jasniju i precizniju sliku o procenjenim količinama i vrstama otpada generisanim u domaćinstvu. Kao metodološka osnova za istraživanje i izradu modela korišćen je UN-Habitat vodič „Waste Wise Cities Tool (WaCT)“. Model je u kontinualnom razvoju, međutim već sada poseduje dovoljno podataka koji sa velikom sigurnošću mogu kreirati rezultate procena generisanih količina otpada iz domaćinstava, kao i njihov morfološki sastav. Model je namenjen kao alat svima koji se bave upravljanjem otpadom, sa akcentom na otpad iz domaćinstava. Samo neki od potencijalih korisnika ovog modela su naučne i stručne organizacije, JLS, JKP, ali i poslovni sektor: operateri sistema upravljanja ambalažnim otpadom, recikleri i dr.
U kontekstu Zelene agende, pouzdani podaci o otpadu iz domaćinstva su nam neophodni kao ulazni podaci za kreiranje zelenih politika u domenu cirkularne ekonomije i ponovne upotrebe, radi lakšeg usklađivanja sa standardima EU u oblasti upravljanja otpadom i dostizanja zadatih EU targeta u oblasti recikaleže i konačno radi lakšeg prevazilaženja lokalnih izazova i poteškoća upravljanja otpadom.Urednici: Dejan Filipović, Velimir Šećerov, Dušan Ristić, Marina Ili
Impacts of recent migration on Belgrade’s housing market dynamics
No full textThe ongoing migration crises, particularly the war in Ukraine and increasing political and economic instability in Russia, have prompted significant waves of people seeking refuge in various European cities. Among these destinations, Belgrade has emerged as a key location for many migrants. As a result, the local housing market has been significantly impacted, leading to shifts in rental prices, property values, and residential behaviour. The growing influx of migrants has intensified population pressure on Belgrade’s housing market, with central neighbourhoods—traditionally the most sought-after areas—seeing a surge in demand. In particular, Russian migrants, facing limited migration options, have played a central role in driving this increase. It has been most evident in rental prices, which have nearly doubled since the migration influx began. While house prices have also risen, they have not escalated at the same rate as rents. The rapid changes in housing market have had a profound impact on the local population, particularly those from lower socioeconomic backgrounds who find it increasingly difficult to afford housing in the face of rising rents and property prices. This shift exposes the vulnerability of Belgrade’s post-socialist, deregulated housing system, which struggles to keep up with rapid demographic and economic changes. This research utilizes quantitative and qualitative methods to explore these issues. Beside in-depth semi-structured interviews which were conducted with experts from major real estate agencies in Belgrade, additional interviews and surveys were conducted with migrants who have settled in Belgrade in order to explore their residential preferences
Migracije uzrokovane klimatskim promenama - iseljavanje stanovništva nakon velikih poplava u Srbiji 2014. godine
No full textU radu se istražuju obrasci iseljavanja stanovništva iz oblasti koje su u Srbiji najviše stradale tokom majskih poplava 2014. godine: Kolubarski i Mačvanski okrug i opština Obrenovac. Oslanjajući se na teorije koje emigraciju opisuju kao najekstremniji oblik adaptacije na klimatske promene, ovaj rad se fokusira na promenu trenda iseljavanja nakon 2014. godine iz opština pogođenih poplavom, i na identifi kaciju razlika u obrascima iseljavanja stanovništva između ugroženih okruga. Analiza se oslanja na podatke o unutrašnjim migracijama stanovništva koje u okviru redovnog godišnjeg izdranja Demografske statistike publikuje Republički zavod za statistiku, kao i na podatke o razmerama poplave iz 2014. godine koje je objavio Republički geodetski zavod. Rezultati su pokazali da su nakon poplave stope emigracije porasle u svim opštinama Mačvanskog okruga i u opštini Obrenovac, a da je nasuprot njima, u opštinama Kolubarskog okruga migracioni odgovor stanovništva bio potpuno drugačiji: stope iseljavanja su opale posle poplave i taj se trend nastavio do danas. Ispitivanje korelacije između stope emigracije i razmera poplave nije pokazalo očekivanu jaku pozitivnu vezu.Urednici: Dejan Filipović, Velimir Šećerov, Dušan Ristić, Marina Ili
