THE IMPACT OF URBANISATION ON LONG-TERM SUSTAINABILITY IN SOUTH ASIA

Contextualization: Despite the progress made by South Asian nations, a recent analysis by the World Bank indicates that the region has faced challenges in harnessing the potential that urbanisation presents to transform their economy and join the ranks of more prosperous nations in terms of prosperity and living standards. As a result, the suburbs and outskirts of large cities have experienced a more rapid expansion of population. The economics of location and space are influenced by urbanisation's embodiment of agglomeration's density, separation, and variety. It is the main reason for the disparity in prosperity between different parts of the country. Objective: Propose to investigate the impact of urbanization on long-term sustainability in South Asia. Methodology: For this article it was used the inductive method, based on primary sources and carrying out documentary and bibliographical research. Results: The study provides clarification and debate on a current issue linked to the impact of urbanisation on environmental, social and economic sustainability and, at the same time, presents some solutions and policies and strategies to minimise this impact. To this end, it takes a critical look at the impact of urbanisation on long-term sustainability in South Asia. It concludes that urban growth has long-term effects on the way we live, work and interact in cities, so it is crucial to plan and build sustainable communities as the world's population moves to cities.

The Brazilian Contemporary Dance Scene of the Periferia

The aim of this article is to discuss the recent changes in scenic dance in Brazil. Until the beginning of the 2000s, scenic dance was primarily practiced by middle class white dancers, whereas more recently there is a greater representation of Afro-Brazilians and socially less privileged people who come from the outskirts of cities (periferia). The author argues that this change of paradigm is happening due to cultural policies implemented by local governments, as they attempted to provide entertaining and creative activities to help diminish violence in large urban centers, starting in the 1990s. Since these cultural policies have been developing and increasing during the last twenty years, and taking into consideration the issues of decolonialization present in the broader panorama of Latin America, this article’s goal is to discuss the growing presence of artists and dance collectives addressing ethnic and social issues in their work in an attempt to challenge established hegemonic values. In order to accomplish this task, the author refers to social theories related to decolonialization and marginalized communities of the periphery as established by various theoreticians, including Frantz Fanon, Milton Santos, Stuart Hall, Boaventura de Souza Santos, Walter Mignolo, and Anibal Quijano.

Public Housing Stock between Recovery and Sustainability: The Case of Tor Bella Monaca in Rome

The buildings and construction sector is responsible for 37% of energy-related CO2 emissions and over 34% of energy demand globally. The redevelopment of the existing residential building stock has become a consolidated policy of the European Commission to implement the objectives of economic recovery and energy transition towards climate neutrality by 2050. This paper illustrates the design experimentation conducted by the Sapienza University team on the recovery of the public housing compartment R5 in Tor Bella Monaca, Rome. The research proposes an original methodology that is ideally replicable for regenerating large public housing districts built on the outskirts of major European cities, characterised by significant technological and social degradation and energy deficiency. This paper provides an overview of the interventions and an evaluation of the method and set of tools developed in drafting the Technical and Economic Feasibility Study at both the neighbourhood and building levels. This contribution is addressed to researchers and public and private organisations dealing with the complexity of the social housing recovery topic, emphasising overall sustainability aspects of interventions in terms of typological and energy refurbishment of buildings, re-activation of open spaces and enhancement of landscape components, and envisioning new services through participatory methods that promote social inclusion.

A spatial autocorrelation analysis of road traffic crash by severity using Moran’s I spatial statistics: A comparative study of Addis Ababa and Berlin cities

Methodological advancements in road safety research reveal an increasing inclination toward integrating spatial approaches in hot spot identification, spatial pattern analysis, and developing spatially lagged models. Previous studies on hot spot identification and spatial pattern analysis have overlooked crash severities and the spatial autocorrelation of crashes by severity, missing valuable insights into crash patterns and underlying factors. This study investigates the spatial autocorrelation of crash severity by taking two capital cities, Addis Ababa and Berlin, as a case study and compares patterns in low and high-income countries. The study used three-year crash data from each city. It employed the average nearest neighbor distance (ANND) method to determine the significance of spatial clustering of crash data by severity, Global Moran's I to examine the statistical significance of spatial autocorrelation, and Local Moran's I to identify significant cluster locations with High-High (HH) and Low-Low (LL) crash severity values. The ANND analysis reveals a significant clustering of crashes by severity in both cities, except in Berlin's fatal crashes. However, different Global Moran's I results were obtained for the two cities, with a strong and statistically significant value for Addis Ababa compared to Berlin. The Local Moran's I result indicates that the central business district and residential areas have LL values, while the city's outskirts exhibit HH values in Addis Ababa. With some persistent HH value locations, Berlin's HH and LL grid clusters are intermingled on the city's periphery. Socio-economic factors, road user behavior and roadway factors contribute to the difference in the result. Nevertheless, it is interesting to note the similarity of significant HH value locations on the outskirts of both cities. Finally, the results are consistent with previous studies and indicate the need for further investigation in other locations.

Porous privacies: Gender, migration, and precarious homes in early twenty-first century narrative films from the French Mediterranean

A prominent trope in so-called banlieue cinema—French cinema focused on housing projects on the outskirts of large French cities largely inhabited by migrants and their descendants—represents precarious migrant homes, and by extension entire neighborhoods, as dysfunctional and cut off from social life. This essay explores representations of precarious migrant homes that resist such polarising media images, and that insist on a porous privacy as a precondition for narrative and subjective development—for the ability to thrive—while pointing out the often gendered and precarious nature of such porosity. The natural and built specificities of the Mediterranean coast have often provided a productively rich set for such revisions, including for auteurs such as Claire Denis and Abdellatif Kechiche to develop their distinctive styles. Lesser-known filmmakers, such as Bania Medjbar and Hafsia Herzi, emerge in the wake of earlier revisionist films. Less focused on developing distinctive styles, they are invested in character-driven stories, and on stories that feature a range of characters and thus narrative options, while pointing out the gendered complexities of precariously porous homes.

Land tenure for farmers is very urgent because land is one of the natural resources that is a place to do farming. Without farming land, it isn't easy to carry out. Recently, land tenure for farmers has decreased, and some farmers even have almost no land to work on. One of the components of farmers experiencing a land crisis is farmers living in urban areas, especially those living on the city's outskirts. This study aims to analyze land tenure institutions for urban farmers and the ecological sustainability of agriculture in the Bangkala sub-district, Manggala sub-district, Makassar City. This research lasted for three months, from June 2021 to August 2021. This study used 21 rice field farmers as informants, determined by the snowball method. How does one urban farmer know as a paddy rice manager? So far, he knows enough other urban farmers. They provide information on other farmers who can provide data, and so on, until the researcher gets information on 21 people. This method is used because urban farmers are hard to find. The data is in the form of primary data obtained through saturated or in-depth interviews, namely obtaining the same or repeated answers from informants using interview sheets. In contrast, secondary data is obtained through available documents to support this research, and the data analysis technique used is a qualitative descriptive analysis. The results showed that the total land tenure by farmers was 18.13 hectares, all of whom were cultivators with a land tenure system through leasing or sakap. On average, per farmer only controls 0.86 hectares of land per person. The control of paddy fields is getting narrower. Based on this condition, land tenure by urban farmers in Bangkala Village, Manggala District, cannot be expected to support ecologically sustainable agriculture.

Explaining the role of land use changes on land surface temperature in an arid and semi-arid metropolitan area with multi-scale spatial regression analysis.

Urban Heat Islands (UHIs), Land Surface Temperature (LST), and Land Use Land Cover (LULC) changes are critical environmental concerns that require continuous monitoring and assessment, especially in cities within arid and semi-arid (ASA) climates. Despite the abundance of research in tropical, Mediterranean, and cold climates, there is a significant knowledge gap for cities in the Middle East with ASA climates. This study aimed to examine the effects of LULC change, population, and wind speed on LST in the Mashhad Metropolis, a city with an ASA climate, over a 30-year period. The research underscores the importance of environmental monitoring and assessment in understanding and mitigating the impacts of urbanization and climate change. Our research combines spatial regression models, multi-scale and fine-scale analyses, seasonal and city outskirts considerations, and long-term change assessments. We used Landsat satellite imagery, a crucial tool for environmental monitoring, to identify LULC changes and their impact on LST at three scales. The relationships were analyzed using Ordinary Least Squares (OLS) and Spatial Error Model (SEM) regressions, demonstrating the value of these techniques in environmental assessment. Our findings highlight the role of environmental factors in shaping LST. A decrease in vegetation and instability of water bodies significantly increased LST over the study period. Bare lands and rocky terrains had the most substantial effect on LST. At the same time, built-up areas resulted in Urban Cooling Islands (UCIs) due to their lower temperatures compared to surrounding bare lands. The Normalized Difference Vegetation Index (NDVI) and Dry Bare-Soil Index (DBSI) were the most effective indices impacting LST in ASA regions, and the 30×30 m2 micro-scale provides more precise results in regression models, underscoring their importance in environmental monitoring. Our study provided a comprehensive understanding of the relationship between LULC changes and LST in an ASA environment, contributing significantly to the literature on environmental change in arid regions and the methodologies for monitoring such changes. Future research should aim to validate and expand additional LST-affecting factors and test our approach and findings in other ASA regions, considering the unique characteristics of these areas and the importance of tailored environmental monitoring and assessment approaches.

The influence of management practices on plant diversity: a comparative study of three urban wetlands in an expanding city in eastern China.

Rapid urbanization has drawn some aquatic environments into the urban texture from the outskirts of cities, and the composition and distribution of plant species in urban wetlands along the urban gradient have changed. Understanding the drivers of these changes will help in the conservation and utilization of urban wetlands. This study investigated the differences in plant diversity and associated influencing factors in three wetlands, Xixi wetland, Tongjian Lake wetland, and Qingshan Lake wetland, which are located in a core area, fringe area, and suburban area of Hangzhou City, respectively. The results showed that a total of 104 families, 254 genera, and 336 species of plants were recorded in the Xixi wetland; 179 species, 150 genera, and 74 families were found in the Qingshan Lake wetland; and 112 species, 96 genera, and 57 families were collected in the Tongjian Lake wetland. The main plant species and flora distribution of the three urban wetlands showed similarities. Indigenous spontaneous vegetation was highest in the Xixi wetland, while cultivated plant species were most abundant in the Tongjian Lake wetland. The introduction of cultivated plants decreased the distance attenuation effect of plant communities, which led to a certain degree of plant diversity convergence among the three wetlands. Eight endangered plants were preserved in the Xixi wetland by planting them in suitable habitats. Ellenberg's indicator values showed that the proportion of heliophilous plants was higher in the Qingshan Lake wetland, while the proportion of thermophilous plants and nitrogen-loving plants in the Tongjian Lake wetland was higher than in the other two wetlands. The importance of artificial interference factors affecting the differences in plant diversity was significantly higher than that of natural environmental factors in urban wetlands. The preservation of spontaneous plants and the introduction of cultivated plants had an importance of 25.73% and 25.38%, respectively. These were the main factors influencing the plant diversity of urban wetlands. The management mode that did not interfere with spontaneous vegetation and confined maintenance to cultivated plants in the Xixi wetland was beneficial for improving wetland plant diversity. Scientific plant reintroduction can also improve wetland plant diversity.

Comparison of the Happiness Level of Farmers at Suburban Villages with Farmers at Remotes Villages

The study aims to analyze the level of happiness of farmers at two villages The research was conducted at X village, Pare sub-district, Kediri Regency (a suburban village), and Y village, Ngancar district, Kediri Regency (a village far from the city center or rural villages). The two villages have different geographical, topographical, cultural, and central commodities. The number of respondents who have been taken is 50 people in each village, so the total is 100. Data were collected by interview using a questionnaire, in-depth discussion, and documentation. The data analysis is descriptive quantitative analysis and the average difference test (unpaired t-test). The results showed that the happiness of farmers in remote areas, who grew pineapples on mountain slopes was higher than food crops farmers in lower plains and on the outskirts of cities with urban infrastructure. Of the 20 indicators of happiness, 18 indicators score significantly higher in farmers who are far from cities, live in the mountains, and grow pineapples. Only two indicators have the same score (i.e., optimism in achieving life goals and satisfaction with religious activities). Life satisfaction, feelings, and meaning of life for farmers remotes villages that live on mountain slopes, pineapple farmers feel more satisfied.

Паблик-арт в историческом городе: визуализация локального культурного кода

The article analyses public art within the framework of the cultural approach – as a form of visualization of the city’s cultural code. The author examines the variants of public art comprehension existing in the Russian academic discourse and identifies the two most common approaches to the interpretation of art in the public space. According to the first approach, public art is interpreted as “commissioned” art, which is an instrument of the state’s ideological policy, and is therefore evaluated negatively. According to the second approach, public art is understood in a less evaluative and more meaningful way, emphasizing the variability of artistic practices existing within it, their focus on communication with society, participation of residents and reflection of locally significant meanings. The article emphasizes the commemorative functions of public art and comprehends its role in the actualization of the city’s cultural memory and representation of urban identity. The author explores what historical, cultural and mythological narratives are depicted on the murals in Veliky Novgorod, created within the framework of the All-Russian Street Art Festival “Pages of History” (2019– 2023). The article proposes to categorize Novgorod murals into the following thematic groups: 1) genius loci; 2) historical subjects; 3) myths and legends; 4) cultural heritage; 5) natural objects; 6) modern heroes. Art in Veliky Novgorod’s public spaces, especially located in typical Soviet districts, serve to individualize the urban environment and create new points of attraction for the city dwellers. Murals have become part of new excursion routes that run both through the symbolic city center and the city outskirts. The author argues that the subjects represented on the murals are authentic for Veliky Novgorod, contribute to the formation of local identity, enhance the imagery of the urban environment and emphasize the uniqueness of the Novgorod cultural landscape.

Creating a Place: Identities Shaped by the Material Traces of the Past. Case-study of the Old Town of Užice


 The paper rests on the idea that the meanings and values of a place are flexible and changing, depending on the cultural and social values. The inhabitants of a certain place share the associations concerning it and its built elements. These shared associations or experiences create the perception of unity and shape a community. Various meanings were ascribed to the Old Town of Užice from the second half of the 14th century until 1863, when it was devastated. During the last four centuries of its existence, it presented a threat for the Christian inhabitants, so after its Turkish crew left, “the Serbs hastily destroyed the fort”. The survey conducted in 2013 showed that neither its position at the outskirts of the modern city, nor its special status gained by the administrative protection (granted in 1949) were sufficient to generate the positive attitude by the local population. By the beginning of the 21st century the Old Town was neglected and did not take part in the life of the modern settlement. With the dissolution of the former state and the abandonment of the traditions associated to the anti-Fascist struggle, Užice lost its esteem. The local authorities, dissatisfied by their position in the changed economic and political circumstances, decided to prioritize the rehabilitation of the Old Town in their strategy of the city regeneration. This meant the reconstruction of the Medieval fortress of Nikola Altomanović (14th cent.), and the Turkish period in the development of the Old Town was totally silenced. The official portals emphasize the Medieval past of the Old Town, in accordance with the modern Serbian identity, that was built and is still confirmed by the research and promotion of the Medieval history and its material traces. The narrative of the organic links between the modern nation and the Medieval heritage is fundamentally naturalized, indicating the Authorized Heritage Discourse in action, and the influence of the state and the experts on the relations a community creates towards the past. The processes that led to the reconstruction of the Old Town confirm that the relationship to spaces is not pre-defined by their physical characteristics, nor stable. The example of Užice vividly illustrates that a society always chooses which values should be emphasized, and which are the ones to be silenced or forgotten.

Factors affecting the operation of the floor of industrial buildings

In recent years, a high rate of construction of industrial facilities, located not only outside the city limits, but also in the conditions of urban development, in most cases on the outskirts of cities, has been observed. Such buildings include: production, transport, logistics or warehouse complexes. The latter, moreover, play a rather important role in the life cycle of any city.
 For the reliable and efficient operation of such structures, in addition to ensuring the requirements for their strength, reliability and durability, which are put forward to the supporting and enclosing structures, it is also necessary to ensure the long-term, trouble-free and safe operation of floors subjected to various influences.
 In recent years, the use of industrial concrete floors, which can be found quite often not only in industrial buildings, but also in places with a high traffic load, for example, floors in warehouses or factories, sales halls, hangars, airports, railway stations, stations, is gaining relevance maintenance, laboratories, which is explained by their high technical and economic indicators, as well as their resistance to the load from equipment and transport, the fall of heavy objects, thermal, vibration, chemical, temperature effects and abrasion.
 In addition, industrial floors should be characterized by high strength, wear resistance, a long service life, maintainability, unpretentiousness in care.
 However, along with this, there are also negative factors regarding the use of concrete industrial floors. Thus, due to the presence of a porous structure, the concrete floor covering is prone to destruction during operation. This leads to the formation of dust, which can rise into the air and fall into respiratory organs. Also, concrete floors are not resistant to chemical solutions that affect resistant to chemical solutions that affect the formation of cracks. Of course, there are methods of combating these negative factors, such as wet cleaning or using a special topping.

House Price Prediction Using Data Mining with Linear Regression and Neural Network Algorithms

The need for housing in big cities is very high because most offices and economic centers are in big cities. Limited land and high demand cause house prices to rise. Many developers build housing on the outskirts of big cities with access to trains and toll roads to make transportation easier. Property developers compete by providing the best prices, various choices of house specifications, ease of the mortgage process, and attractive promotions such as no down payment. A house is a long-term investment whose price increases yearly, so proper analysis is needed to buy a place to live in. Several factors influence the price of a house, including location, land area, building area, building type, and so on. This research aims to create a house price prediction model using the Linear Regression Algorithm and Neural Network so that the results can be useful for property agents in predicting house sales or from the buyer's side in predicting house prices. The results of this research use the Linear Regression Algorithm RMSE 0.775, while the Neural Network Algorithm uses RMSE 0.645. From this research, modeling using the Linear Regression Algorithm has better results. Still, the Linear Regression Algorithm and Neural Network Algorithm have RMSE results that are close to accurate and have small errors.

Between Tradition and Experiment: The Idea of a New University

From the mid-1960s to the mid 1970s, three new universities were established in Denmark: Odense (1966), Roskilde (1972) and Aalborg (1974). Until then only two universities existed in Denmark: Copenhagen (1479) and Aarhus (1928). Located on the outskirts of the major cities, the new institutions played an important part in reforming and transforming higher education in Denmark. The youngest university, Aalborg University, is approaching its 50th anniversary. This is an opportunity to take a step back and examine the university in long-term perspective. In this article, I investigate the discussions and expectations concerning the establishment of the university in the period 1958–1974. Based on contemporaneous debates in the regional newspaper Aalborg Stiftstidende and interviews with several key figures, the study seeks to analyze the underlying ideas and ideals which characterized the discussion by asking the following questions: What was the projected purpose of the new university? What ideals were expressed in the debate? In the last part of this article, I will reflect on the historiographical developments in the history of the university. In recent years, several new approaches have expanded the field and made visible new aspects of the institutions’ histories. I will discuss why a focus on the ideas, ideals and expectations of the university, and thereby of the university as a knowledge institution, is essential to include in a study of its history.

GIS, satellite image and risks in urban and Peri-urban areas; methodological aspects

Evoking the risk, even in urban areas, brings us back almost mechanically to the risks of flooding, or even silting up in certain regions. However, there are many other risks in cities that are still little or no explored using GIS solutions. We will mention in particular the problems encountered in the outskirts of cities and so-called sensitive areas, but also those due to the very configuration of certain neighborhoods (concentration of buildings, absence of support infrastructure) which generate risk situations. , or rather danger. Of course, we cannot overlook the problem of old neighborhoods that are abandoned in certain regions, but where populations still live and are exposed to multiple dangers following the continuous dilapidation of buildings. Finally, it is useful, even necessary, to also mention the perception of risk, which is sometimes extremely vague, in the minds of populations who end up generating their own risk themselves. In this article, we briefly examine the notion of risk, its perception in the collective mind and its consequences in everyday life. We then present, on a practical example, the contribution of GIS solutions and satellite imagery to the analysis and forecasting of risk in urban areas. The examples are taken from Algerian towns in the pre-Saharan zone. We will take the city of Laghouat as an example and we will develop the aspect of risk generation by the individual and society as a whole; we will also see how the local authority contributes to this situation of generation of risk or danger and, above all, how it can remedy it.

Modeling Impact of Transportation Infrastructure-Based Accessibility on the Development of Mixed Land Use Using Deep Neural Networks: Evidence from Jiang’an District, City of Wuhan, China

Mixed land use (MLU) plays a crucial role in fostering a sustainable urban development, vibrant communities, and efficient land utilization, providing a viable solution for smart growth, inclusive public transit, and urban sustainability. This study employs deep neural network (DNN) models: multilayer perceptron (MLP), and long short-term memory (LSTM), to analyze the effect of the transportation infrastructure-based accessibility on the prevalence of MLU patterns, based on the following data: infrastructure-based accessibility measures represented by the logsum (or transport supply), MLU patterns at the parcel level, and floor space prices by space type, for the years 2012 and 2015. Furthermore, the proposed methods are applied to the Jiang’an District of the city of Wuhan, China, at the parcel level as the case study. The study results reveal that MLU is predominantly accessible in areas close to the city center, characterized by a high density, and is relatively scarce on the city outskirts. Notably, parcels exhibiting mixed residential–commercial and residential land-use patterns underwent significant changes between 2012 and 2015, particularly in regions with robust accessibility via non-motorized modes and public transit, specifically in the central and southern parts of Jiang’an District. This transition is evident under scenario 3 (walk, bike, bus, subway) and scenario 6 (walk, bus, car) considered in this study. Furthermore, the study observed a substantial expansion in mixed commercial–residential and commercial districts, significantly near the high-transit accessibility area of subway line 1, as demonstrated in scenario 7 (bike, subway, taxi). The results from the MLP models show a mean relative error (MRE) of 4.7–14.08% for the MLU, and the LSTM models show an MRE of 3.74–10.38% for the MLU. More importantly, both the training and forecasting errors of the above models are lower, in most cases, than those reported in the literature. Moreover, these results indicate that the transportation supply or the infrastructure-based accessibility (represented by logsum) significantly influences MLU patterns.

Smartphone Addiction among Syrian Medical Students

Abstract Background Smartphone use has increased and has become an essential part of daily life. This study aimed to assess the prevalence of smartphone addiction among medical students in Syria, investigate its potential effects on insomnia and sub-health. Methods This study was conducted in Syria from October 6th to November 12th, 2022. We included Syrian medical students across all Syrian medical colleges. The survey consisted of four questions, sociodemographic information, insomnia scale, Sub health status questionnaire (SHSQ-25), and Smartphone Addiction Scale (SAS). The data were analyzed using IBM SPSS Version 28.0. Results A total of 1437 participants completed the survey, and their mean age was 21.4 (SD = 1.8). Our analysis identified the prevalence of smartphone addiction, insomnia, and subhealth among medical students as 62.5%, 23.7%, and 28.4%, respectively. The mean hours number of smartphones used daily was (6±2.8). About half of the respondents use their phones for more than six hours a day (50.2%), and over half of the participants (52.8%) consider themselves addicted to their smartphones. Among students diagnosed with smartphone addiction, 43.2% reported using their phones for more than six hours daily, and 41.1% perceived themselves as smartphone addictive. Students residing in the city's outskirts exhibit a higher likelihood of addiction than their urban counterparts (OR = 1.5, P value < 0.05). Furthermore, individuals who avoid using their smartphones before bedtime exhibit a lower propensity towards developing smartphone addiction than those who do (OR = 2.7, P value < 0.05). As well, we defined a significant inverse correlation between the smartphone addiction score and the SHS (r2= -0.114, P value< 0.001). Conclusions We indicate that smartphone addiction negatively affects the sleep quality and subhealth of medical students, particularly among those who use their smartphones before sleeping and those who consider themselves smartphone addicts. Key messages • We indicate that smartphone addiction has detrimental impacts on the quality of sleep and subhealth of medical students, particularly those who use their smartphones before sleeping. • It is suggested that medical institutions conduct educational initiatives regarding the negative consequences of smartphone addiction, including its potential long-term impact on mental health.

ОРНІТОФАУНА СЕЛА СОЛОНКА НА ЛЬВІВЩИНІ: АНАЛІЗ СПОСТЕРЕЖЕНЬ ЗА 2010–2023 РОКИ

This article analyzes the avifauna species in Solonka village, a distinct area situated on Povitriana Street, located on the southern outskirts of Lviv city. Data on bird species diversity were collected throughout different seasons from 2010 to 2023. Over this period, a total of 63 bird species were observed. Between 2010 and 2016, there were 46 nesting species. Anthropogenic factors significantly influence the species diversity and population of birds in Solonka village. Gardens, summer cottages, areas adorned with fruit trees, sewage treatment plants, and ornamental plantings near houses provide birds with food, shelter, and nesting opportunities. The primary causes of mortality among both young and adult birds each year are the presence of a large number of stray cats and dogs. During the winter months, local residents actively feed passerine birds. Additionally, each year, some nests and chicks are unintentionally disturbed by children and teenagers. The avian population in the area is predominantly composed of small birds that inhabit trees and shrubs. From 2022 to 2023, we observed birds belonging to six orders: Ancerinae (Anseriformes), Falconidae (Falconiiformes), Galliformes (Galliformes), Columbidae (Columbiformes), Woodpeckers (Piciformes), Old world sparroews (Passeriformes). In 2021, The Bohemian waxwing (Bombycilla garrulous Linnaeus, 1758) were observed. They were registered in separate winters. In the winter of 2022, for the first time during 13 years of observations, the marsh tit (P. palustris Linnaeus, 1758), the crested tit (P. cristatus Linnaeus, 1758), the common redpoll (Acanthis flammea Linnaeus, 1758) and the short-toed brachydactyla (C. brachydactyla Brehm, 1820) and the falcon (Falconidae). Martins and terns (Laridae), the common kingfisher (Alcedo atthis Linnaeus, 1758), and gray heron (Ardea cinerea Linnaeus, 1758) regularly visit reservoirs in the vicinity of Solonka village. The listed species do not nest here. The common moorhen (Gallinula chloropus Linnaeus, 1758) and Eurasian coots (Fulica atra Linnaeus, 1758) nest in the ponds every year. There are known cases of mallard nesting. After 2010 jackdaws and owls stopped nesting on the surveyed territory.
 The migration route of the gray crane (Grus grus Linnaeus, 1758) and the white stork (Ciconia ciconia Linnaeus, 1758) passes through the territory of Solonka village, where these birds are regularly observed during both autumn and spring migrations.
 In general, the number of bird species observed in the area of Solonka village is lower than that in the residential area of Lviv. In Lviv, a total of 84 bird species were recorded between 2006 and 2018. In contrast, our surveys in the Solonka village area have documented only 63 species of birds. This indicates a difference of 20 bird species between the two locations we studied. Our observations span the period from 2010 to 2023. 
 To put this into perspective, in 1994, Lviv was home to 197 bird species. This significant decrease in species diversity over the last three decades can be attributed to various factors, with one of the most prominent being the substantial transformation of biotopes.
