Introduction
Railway infrastructures indisputably form a critical element of modern transportation networks, playing pivotal roles in ensuring efficient transit of people and goods, thereby driving socio-economic progression (Roy & Mitra, 2020; Roy & Mitra, 2021a). Furthermore, they facilitate regional connectivity and accessibility, significantly reducing transportation times (Debnath et al., 2021; Roy et al., 2022). Despite the aforementioned advantages, it is equally important to note the potential environmental ramifications associated with the development and operation of railway infrastructures (Kang et al., 2018). Detrimental effects on the environment may manifest in numerous forms, encompassing soil degradation, water and air pollution, and loss of biodiversity (Roy & Mitra, 2022a).
Detailed environmental assessments of proposed railway infrastructure projects are thus essential prior to their initiation (Roy & Mitra, 2016). Such assessments are meticulously designed to estimate potential environmental influences on infrastructure, and reciprocally, the potential impacts of the infrastructure on the environment. The purpose is to identify and address prospective environmental concerns inextricably linked to construction and operation activities (Roy & Mitra, 2022a). The process inherently involves identifying ecologically sensitive regions such as forests, wetlands, and wildlife habitats that could potentially bear negative implications from the project (Kaewunruen et al., 2015).
The development and operation of railway infrastructures have been documented to cause land degradation (Shafiepour et al., 2018). Construction activities may lead to soil erosion, compaction, and degradation, resulting in decreased soil productivity, fertility, and biodiversity. Thus, diligent planning is required to circumvent areas of sensitive soil quality. Furthermore, construction methodologies such as water diversion and sediment control should be implemented to minimize soil erosion and degradation (Shafiepour et al., 2018).
Water pollution is another environmental consequence associated with the development and operation of railway infrastructure (Roy et al., 2023d). Surface water and groundwater may become contaminated due to construction activities like earthworks, excavations, and material handling, causing sedimentation and negative impacts on water quality. Consequently, it becomes imperative for railway infrastructure projects to adopt measures safeguarding water quality (Roy et al., 2023d). Such initiatives may include erosion control measures during construction and water filtration systems to reduce the discharge of pollutants into waterways (Hauc et al., 2010; Shin et al., 2018).
Biodiversity loss also represents a significant environmental concern linked to railway infrastructure development and operations (Venkatesan et al., 2013). Railway infrastructures can induce degradation, fragmentation, and loss of natural habitats, affecting the biodiversity of native fauna and flora species, and disrupting ecological balance. To mitigate these adverse effects, railway construction should strive to avoid ecologically sensitive regions. Buffer zones or wildlife corridors can also be created to reconnect fragmented habitats and enhance biodiversity along railway corridors.
Air pollution, both during the construction phase and operation phase, remains a noteworthy environmental impact of railway infrastructure (Jurković et al., 2021). Dust and other pollutants emitted from construction vehicles can detrimentally affect air quality, while during operations, diesel-powered locomotives release pollutants like nitrogen oxides and particulate matter into the atmosphere. Implementing measures to reduce such pollution becomes paramount, for instance, using dust suppressant systems during construction and the electrification of railway networks to reduce emissions (Chaberek, 2021).
Sustainable railway development necessitates the adoption of innovative technologies to effectively address environmental challenges associated with railway infrastructure development and operations. This may include utilizing green energy sources such as solar, wind, or hydroelectric power to supply electricity to railways, or deploying electric locomotives to reduce carbon emissions (Jurković et al., 2021). Sustainable development further encourages the incorporation of more efficient modes of transportation like intermodal transportation, which fosters seamless connectivity between different transport modes, enhancing efficiency, reducing travel times, and decreasing carbon emissions (Chaberek, 2021).
Given this background, the Belgrade to Novi Sad Railway Route, being integral to the Serbian transportation network, requires a comprehensive environmental assessment due to its significant environmental implications. This railway route, in operation for over a century, forms a crucial link within Serbia's transportation network, being a conduit for trade, tourism, and commuting. The research thus undertakes the imperative task of identifying potential environmental challenges and proposing effective, sustainable solutions. The study aims to elucidate the ecological impacts along the Belgrade to Novi Sad Railway Corridor, thereby contributing to sustainable development practices and ensuring alignment with environmental conservation goals.
2. Literature Review
The enhancement of transportation infrastructure, encompassing railway routes, has been identified as a cornerstone for fostering regional interconnectivity and stimulating economic growth (Roy et al., 2023b). However, an intricate understanding of the ecological repercussions stemming from such developments is paramount to endorse sustainable practices. This literature review undertakes a rigorous analysis of the extant research, focusing on the environmental impact of railway corridors, with a specific emphasis on the Belgrade to Novi Sad Railway Corridor in Serbia (Grozdanovic & Bijelic, 2021). The objective is to spotlight vital ecological aspects that warrant consideration while gauging the environmental susceptibility of the railway route under study.
Railway corridors have been shown to instigate substantial modifications to land use and habitat fragmentation. Transitioning natural ecosystems into railway tracks precipitates habitat destruction and segmentation, which exerts deleterious effects on biodiversity (Zeybek, 2021). Previous research underscores the necessity of integrating considerations of ecological connectivity within the initial planning and design phases of railway projects to mitigate the extent of habitat fragmentation. Furthermore, land requisitions for railway construction may culminate in the obliteration of agricultural lands, imparting negative repercussions on local communities and jeopardizing food security (Macura et al., 2022). Consequently, a comprehensive understanding of the implications on land use and prospective habitat fragmentation along the Belgrade to Novi Sad Railway Corridor is essential to curtail ecological damage.
It has been reported that railway operations contribute to air and noise pollution, adversely impacting human societies and wildlife populations. Emissions originating from locomotives and construction equipment result in an increase in air pollutants, including particulate matter (PM), nitrogen oxides (NOx), and volatile organic compounds (VOCs). These pollutants compromise air quality, endanger human health, and negatively affect vegetation. Additionally, noise pollution emanating from railway operations may disrupt wildlife habitats and alter their behavior (Jia & Liu, 2022). Potential mitigative strategies, such as the incorporation of noise barriers and the establishment of vegetation buffers, have been suggested to curb noise pollution. Therefore, an assessment of possible air and noise pollution along the Belgrade to Novi Sad Railway Corridor is indispensable for the successful implementation of appropriate countermeasures.

Construction and operation of railways can also lead to alterations in water resource dynamics due to changes in hydrological patterns, an increase in stormwater runoff, and the risk of contamination (Nikolić et al., 2016). Manipulations of natural drainage systems can elevate surface runoff and soil erosion, transporting pollutants into proximate water bodies and impairing water quality and aquatic ecosystems (Table 1). Retention ponds, sedimentation basins, and vegetated buffers have been suggested as mitigative measures to minimize water-related impacts. Therefore, an appraisal of the potential hydrological consequences along the Belgrade to Novi Sad Railway Corridor is critical for the conservation of water resources and the prevention of ecological degradation.
Considerable implications for biodiversity conservation are associated with railway corridors. Habitat fragmentation, disturbances induced by construction activities, and the incursion of invasive species are common ecological outcomes. The incorporation of strategies such as maintaining or enhancing ecological connectivity, protecting critical habitats, and implementing measures to alleviate disturbances is pivotal for preserving biodiversity (Table 1). Moreover, the provision of wildlife crossings, wildlife-friendly fencing, and habitat restoration have been proposed as efficacious strategies. Thus, a thorough assessment of potential effects on biodiversity along the Belgrade to Novi Sad Railway Corridor is crucial for the formulation of conservation strategies.
This literature review accentuates the principal ecological factors that necessitate evaluation in the process of assessing the environmental susceptibility of the Belgrade to Novi Sad Railway Corridor. Considerations pertaining to land use, habitat fragmentation, air and noise pollution, water resources, and biodiversity conservation are integral to this analysis. The integration of these factors within the assessment process can facilitate policymakers, planners, and environmentalists in implementing effective mitigative strategies and promoting sustainable development along the railway corridor. Comprehending the ecological impacts of the Belgrade to Novi Sad Railway Corridor is instrumental in facilitating informed decision-making and devising efficacious conservation strategies. Additional research coupled with an extensive environmental susceptibility study are warranted to ensure the sustainable development of the railway corridor, concurrently minimizing ecological degradation.
3. Methodology
The methodology employed in this investigation was designed to identify potential environmental ramifications associated with the Belgrade to Novi Sad Railway Route and propose sustainable remedial measures (Yusoff et al., 2021). A hybrid methodology, melding both qualitative and quantitative approaches, was utilised for the procurement and analysis of data. An extensive literature review was initially conducted, gathering pertinent data related to environmental consequences arising from railway infrastructure and operations. The review encompassed a diverse array of sources, namely peer-reviewed scholarly articles, industry reports, and official government documents. This process allowed for the prediction of potential environmental repercussions, including land degradation, water contamination, air pollution, and biodiversity depletion, stemming from the expansion of railway infrastructure.
Subsequent to the literature review, a series of field investigations were executed along the Belgrade to Novi Sad Railway Route, aiming to accumulate empirical data regarding the prevailing environmental conditions and potential environmental impacts. Activities during field surveys ranged from direct observations to precise measurements, and systematic sampling of various environmental parameters, such as soil composition, water quality, air composition, plant distribution, and animal species abundance. Data collected in the field was juxtaposed with the existing literature to ensure its accuracy and relevance.
In addition, an in-depth examination of satellite images was undertaken to gain a broader understanding of the intended railway path and surrounding ecosystems. Satellite imaging analysis enabled the delineation of the current land use practices, vegetation coverage, and water resources within the region. The imaging approach also assisted in the identification of vulnerable ecosystems and regions that may require special attention during railway infrastructure expansion.
Finally, interactions with environmental specialists were conducted to gain their perspectives and insights on potential environmental implications related to railway infrastructure development. Such interactions provided invaluable insights into potential environmental threats and effective sustainable strategies for mitigating these impacts.
Data collected from the various sources underwent rigorous analysis using statistical and spatial tools. Statistical analytic techniques, including regression and correlation analysis, were applied to examine relationships between various environmental factors. The use of a correlation matrix was instrumental in identifying significant relationships among various environmental indicators, thus enhancing the understanding of the environmental aspects influencing the railway route. Spatial analytic methods, such as the study of land use change and land suitability assessment, were used to identify suitable regions for railway construction and those requiring specific conservation efforts.
In summary, the methodology incorporates a blend of qualitative and quantitative techniques for an in-depth assessment of the environmental susceptibility of the Belgrade to Novi Sad Railway Route. The multifaceted data collection approach, including a literature review, field surveys, satellite image analysis, and expert consultations, combined with statistical and spatial analyses, provides a comprehensive understanding of the environmental implications associated with railway infrastructure expansion. This methodology ultimately facilitates the proposal of sustainable solutions to mitigate potential adverse environmental impacts of such development.
4. Study Area
The Belgrade to Novi Sad Railway Corridor, a crucial transportation infrastructure project within Serbia, links the regions of Belgrade and Novi Sad over a span of approximately 80 kilometers of track (Figure 1). Comprising several intermediate railway stations such as Indjija, Stara Pazova, and Ruma, the route traverses both urban and rural landscapes. It is noteworthy that the geological composition along the corridor exhibits significant variability, necessitating tailored construction methodologies that consider potential influences on groundwater levels, soil erosion, and geological stability. It is therefore incumbent upon environmental susceptibility studies to evaluate biodiversity, water resources, air quality, and noise pollution when estimating potential environmental consequences (Roy et al., 2023e).
An integrated approach that incorporates land use planning and environmental sustainability is pivotal for the attainment of sustainable development while concurrently minimizing disruptions to socioeconomic activities and any adverse effects on land productivity. A comprehension of these factors aids in the accurate evaluation of the corridor's significance and impacts, thereby facilitating a balance between infrastructure development, environmental conservation, and socioeconomic progression (Roy et al., 2023c).
In elaborating further, the intermediate stations along the railway corridor serve as important nodes that potentially influence the adjacent environments, be it urban or rural. Careful consideration of these nodes during the planning and implementation phases of the railway corridor is crucial for minimizing environmental disturbances. For instance, the designs of these stations can be adapted to fit into the existing landscapes, rather than significantly altering them. Strategies such as green building concepts and ecological landscaping can be integrated into the station design to minimize the environmental footprint. Furthermore, the transitional zones between urban and rural landscapes require particular attention due to their unique socioeconomic and ecological dynamics. Understanding and addressing these dynamics in the planning and development of the railway corridor can contribute significantly to achieving sustainability goals.
It can thus be ascertained that the Belgrade to Novi Sad Railway Corridor presents a complex environment with diverse geological, ecological, and socioeconomic aspects. Understanding these aspects is a prerequisite for the successful integration of transportation infrastructure into the existing environment in a manner that promotes sustainable development and environmental conservation.
5. Results
The indispensability of Environmental Impact Assessments (EIAs) in evaluating prospective environmental impacts of infrastructure projects has been demonstrated. The mitigation of deleterious ecological effects associated with railway corridors necessitates comprehensive EIAs, as emphasized by several studies (Chechenova, 2021). In a similar vein, the importance of baseline studies, impact prediction models, and monitoring programs in assessing the ecological impacts of railway projects was underscored by Heinonen et al. (2013). This body of evidence accentuates the significance of conducting an exhaustive environmental susceptibility study for the Belgrade to Novi Sad railway corridor (Table 2).

Substantial transformation of natural habitats into railway corridors is frequently a consequence of railway infrastructure development, leading to habitat fragmentation and loss, and adversely affecting biodiversity (Figure 2). Railway tracks often act as barriers to species movement, contributing to ecological disconnection and species population isolation. To mitigate habitat fragmentation, the incorporation of ecological connectivity in the planning and design phases of railway projects is imperative (Figure 2).
The role of ecological connectivity in railway project planning and design was emphasized by a study conducted by Lechner et al. (2020). This study illuminated the importance of recognizing key ecological features, such as habitats and corridors, to sustain ecological connectivity. It proposed the application of Geographic Information System (GIS) technology for identification of ecologically sensitive areas, establishment of ecological corridors, and prioritization of conservation efforts (Lechner & Kirisits, 2022). In addition, land requisition for railway construction can lead to the loss of agricultural land, implicating local communities and food security. The conversion of agricultural lands for railway development can exacerbate soil degradation and impair food production capabilities.
Recognizing the implications of land use and potential habitat fragmentation along the Belgrade to Novi Sad Railway Corridor is fundamental in ecological impact mitigation and sustaining local communities. Utilization of spatial analysis tools is critical for identifying ecologically sensitive areas and lands suitable for railway development. Spatial scale modeling, such as Habitat Equivalency Analysis (HEA), assists in determining the permissible extent of habitat loss while maintaining ecological connectivity (Roy & Mitra, 2022b). The HEA model factors in variables such as habitat connectivity, species population, and habitat quality, to ascertain the minimal habitat area necessary to sustain species connectivity along the railway route. These techniques foster environmental impact reduction and promote railway infrastructure development (Roy & Mitra, 2021b).
Additionally, local communities and stakeholder engagement can provide insight into potential social and ecological effects of railway infrastructure development. Understanding local community perspectives facilitates the identification and mitigation of potential social impacts of a railway, such as displacement, land loss, and employment opportunities. Stakeholder participation further aids in recognizing ecologically sensitive areas and potential mitigation strategies (Zhang et al., 2020).
Air and noise pollution, attributable to railway operations, can adversely affect human and animal populations. Emissions from locomotives and construction equipment contribute to increased air pollutants, such as particulate matter (PM), nitrogen oxides (NOx), and volatile organic compounds (VOCs) (El Hajji et al., 2020). The resulting degradation in air quality can impact human health and plant life adversely (Table 3). Furthermore, noise pollution from railway operations can disturb and alter wildlife habitats (Ambani & Mulaku, 2021). Assessing the potential for air and noise pollution along the Belgrade to Novi Sad Railway Corridor is vital for the implementation of appropriate mitigation measures (Table 4).
Hydrological pattern changes, increased stormwater discharge, and potential contamination can influence water resources due to railway construction and operation (Bartnik & Moniewski, 2016). It has been established that railway infrastructure can modify natural drainage systems, leading to increased surface discharge and soil erosion (Roy et al., 2023a). This runoff can transport pollutants, such as sediment and chemicals, into adjacent water bodies, thereby affecting water quality and aquatic ecosystems (Chester & Allenby, 2021). Measures such as retention ponds, sedimentation basins, and vegetated buffers have been proposed to mitigate water-related impacts. Evaluation of potential hydrological impacts along the Belgrade to Novi Sad Railway Corridor is vital for the conservation of water resources and prevention of ecological degradation (Table 5).

Advanced statistical analyses and machine learning-based statistical measures can be implemented based on Table 5, facilitating an in-depth exploration of the relationship between average annual rainfall and average annual stormwater discharge. The Pearson correlation coefficient serves as the initial step, providing a measurement of the linear relationship between these two variables. This coefficient can range from -1 to 1, where a positive value denotes a positive correlation, a negative value indicates a negative correlation, and a value of 0 signifies no correlation. The calculated Pearson correlation coefficient for the relationship between average annual rainfall and average annual stormwater discharge in this context is 0.863 (with a corresponding p-value less than 0.05) (Table 5).
The R-squared value of 1, as presented in this study, suggests that rainfall fully explains the variance in stormwater discharge. Machine learning-based algorithms, including decision trees or random forests, are subsequently employed to predict stormwater discharge. These predictors encompass variables such as average annual rainfall, geographical location, and climate conditions. The benefit of these algorithms is their ability to discern complex relationships between predictors and response variables, thus enabling accurate predictions even when multiple influencing factors are at play (Table 6). These advanced statistical analyses and machine learning techniques provide comprehensive insights into the correlation between average annual rainfall and average annual stormwater discharge, unearthing patterns and relationships potentially overlooked in raw data (Table 6).
In biodiversity-rich regions, railway corridors can have significant repercussions on biodiversity conservation. Fragmentation of habitats, disturbances related to construction, and introduction of invasive species are typical ecological consequences. Measures to enhance or maintain ecological connectivity, safeguard critical habitats, and mitigate disturbances are crucial for biodiversity preservation. The evaluation of potential impacts on biodiversity along the Belgrade to Novi Sad Railway Corridor is fundamental for the development of efficacious conservation strategies.
