- Generative Adversarial Approach to Urban Areas’ NDVI Estimation: A Case
Study of Łódź, Poland
Abstract: Generative adversarial networks (GAN) opened new possibilities for image processing and analysis. Inpainting, dataset augmentation using artificial samples, or increasing spatial resolution of aerial imagery are only a few notable examples of utilising GANs in remote sensing (RS). The normalised difference vegetation index (NDVI) ground-truth labels were prepared by combining RGB and NIR orthophotos. The dataset was then utilised as input for a conditional generative adversarial network (cGAN) to perform an image-to-image translation. The main goal of the neural network was to generate an artificial NDVI image for each processed 256 px × 256 px patch using only information available in the panchromatic input. The network achieved a structural similarity index measure (SSIM) of 0.7569 ± 0.1083, a peak signal-to-noise ratio (PSNR) of 26.6459 ± 3.6577 and a root-mean-square error (RSME) of 0.0504 ± 0.0193 on the test set, which should be considered high. The perceptual evaluation was performed to verify the method's usability when working with a real-life scenario. The research confirms that the structure and texture of the panchromatic aerial RS image contain sufficient information for NDVI estimation for various objects of urban space. Even though these results can highlight areas rich in vegetation and distinguish them from the urban background, there is still room for improvement regarding the accuracy of the estimated values. The research aims to explore the possibility of utilising GAN to enhance panchromatic images (PAN) with information related to vegetation. This opens exciting opportunities for historical RS imagery processing and analysis.

- The Analysis of Fire Hotspot Distribution in Kalimantan and its
Relationship With Enso Phases
Abstract: Kalimantan experiences fire hazards almost every year, which threaten the largest tropical forest in Southeast Asia. Climatic conditions, such as increasing surface temperature and decreasing rainfall, become important especially when El Nino Southern Oscillation (ENSO) occurs. Studies on fire are commonly conducted based on the climatic condition such as the dry or wet season, but those which focused on analysis of fire occurrences with the specific ENSO phases are still limited. This study aims to identify the spatial and temporal distribution of rainfall, land surface temperature, and soil moisture and analyses the distribution of hotspots in Kalimantan from 2014 to 2020 during different ENSO phases. The data used are Moderate Resolution Imaging Spectroradiometer (MODIS) for hotspot analysis, Global Precipitation Measurement (GPM) for rainfall analysis, MODIS Land Surface Temperature (LST) for surface temperature analysis and Soil Moisture Active Passive (SMAP) for soil moisture analysis. The methods used were descriptive and spatial analyses based on each ENSO phase, which were then combined to analyse the temporal and spatial distribution of fire, rainfall, LST and soil moisture. The temporal distribution shows a positive relationship between ENSO, rainfall, LST, soil moisture and hotspots with a confidence level of 90% in the dry months of August–October. Fire occurred in most parts of West and Central Kalimantan, associated with low elevation, organic soil types and agricultural peatland. The average trend of increasing hotspots is 17.4% in the El Nino phase and decreasing hotspots by 84.7% in the La Nina phase during August–October in Kalimantan.

- Tourism Development in the Borderlands of Romania: A Case Study of the
Danube Gorge–Iron Gates
Abstract: Border areas are a real challenge for tourism development. Usually associated with the periphery from a socio-economic point of view, these areas often have natural potential and attractive landscapes that have been little transformed by human activity and numerous historical and cultural tourist attractions. Although these areas have considerable tourism potential, this is not sufficient for the sustainable development of tourism and the exploitation of this potential is strongly influenced by the degree of permeability of the border. This is the case of the Romanian-Serbian border, which overlaps the most spectacular sector of the Danube – the Iron Gates Gorge. The main aim of this article is to analyse the role of tourism in the development of border areas and how it functions in a particular territorial context: the Danube Gorge located at the border between Romania and Serbia. The Romanian-Serbian border currently functions as an external border of the European Union in a favourable historical and political context, given the tradition of good neighbourliness between the two entities, the states located on either side of the Danube. However, the communist period altered the prospects for tourism development in this region through a very drastic and controlled border regime, even though the area benefited from major investment projects, such as the dam and hydroelectric power station at Porțile de Fier, built in the 1970s in cooperation with the former Yugoslavia. An analysis of the statistical data on tourism development shows that tourist traffic is on the increase, although there is a contradiction between the upward trend in tourist flows and the backwardness of large-scale tourist infrastructure, with the dominant type of accommodation being small, flexible, and rural accommodation that does not require large investments. The results presented in this article can be summarised in the general conclusion that the development of tourism in the Danube Gorge–Iron Gates remains dependent on the political factor and the border regime, even though the region has a remarkable tourism potential.

- Sources of Mapping used in Humanitarian Emergencies: The Case of Ebola
Abstract: The need to rapidly respond to health emergencies has generated various institutional initiatives to identify their location, through mapping. This study employs a qualitative-exploratory method, based on the daily monitoring of eight Ebola epidemics between 2013 and 2021, to make an assessment of the usefulness of maps created specifically for Ebola. The results show that at least 14 organisations produce maps in the face of emergencies and epidemics such as Ebola. Consequently, it has been possible to design a search plan to aid in the monitoring of emergencies and to design an Ebola map with data obtained from these organisations and the initiatives they promote, which confirms the usefulness of these data sources and maps.

- Regional Green Transition: Cases of Polish and Russian Regions
Abstract: The green transition unfolding on a global scale is much less studied at the regional level, although its outcomes and management are strongly place-specific. This article presents a comparative study of green transition strategies in the Silesian Voivodeship (Poland) and the Khanty-Mansiysk Autonomous Okrug (KMAO) – Ugra (Russia), based on a qualitative content analysis of regional legislation and strategies. The regions share common specialisation in fossil fuel mining and have inherited some features of post-socialist economies. Research shows three common features of green transition policies in the studied regions. Firstly, much attention is paid to the dissemination of information about green transition and its benefits. Secondly, research on various green subjects and educational programmes for green market requirements are developed. Thirdly, it is planned for renewables to have a larger proportion in regional energy mixes. By mid-century, both regions are expected to reach climate neutrality, although by using different paths of development. Coal mines are planned to be closed down in the Silesian Voivodeship by 2050, while the KMAO – Ugra will retain its oil-mining specialisation but diversify it with hydrogen production.

- The Influence of Built Environment and Socio-Economic Factors on Commuting
Energy Demand: A Path Analysis-Based Approach
Abstract: Transport is the second energy consumer sector after housing in Algeria. In this article, we explore the energy implication of commuting by considering a panel of socio-economic (SE) and built environment (BE) driving factors. The method is based on four steps: (i) The first step is to identify the main and potential drivers from the literature review and to propose a model that summarises the main assumptions that could explain the volume of commuting and the resulting energy consumption. (ii) In the second step, we designed and distributed 700 questionnaires in the municipality of Djelfa and retained 184 valid questionnaires in the final study sample. (iii) In the third step, we developed a method adapted to urban areas to quantify energy consumption as a function of the distance travelled, the type and density of occupation by means of transport and the type of fuel. (iv) The fourth step is to check the fit of the hypothetical model with a path analysis-based approach. The model developed identifies 15 factors, of which five have a direct impact and 10 have an indirect impact on the energy consumption of commuting. The model shows that building density and the age of the respondent can reduce the energy consumption of commuting by up to −15% and −12% respectively; whereas the number of cars by housing and the round-trip frequency could increase the energy consumption up to 38% and 27% respectively. Our results suggest a structuring role of the socio-economic characteristics of households in explaining the energy consumption of commuting.

- How the Analytical Hierarchical Process and Revitalisation Work Together:
A Case Study of Poland
Abstract: Due to the multifaceted nature of the revitalisation process, its evaluation and monitoring, as well as possible comparisons, are complex and difficult to carry out. Evaluation of the revitalisation process currently poses a challenge for all municipalities. The article aims to compare the revitalisation process in the two Polish cities of Toruń and Bydgoszcz. The analysis was based on two financial perspectives: 2007–2015 and 2016–2023. The authors chose a multi-criteria analysis method based on the analytical hierarchical process (AHP) as the main research method. The results show that the Local Revitalisation Programme of the City of Toruń for the years 2007–2015 had the best impact on the revitalisation process. Using the AHP method, we could carry out a multidimensional evaluation of the revitalisation process. Moreover, it allowed us to combine different elements of the evaluation of the revitalisation process and transform them into one synthetic result, ranking each programme in a hierarchy. At the methodological level, the article presents a new approach to conduct research in socio-economic geography, using the tool of multi-criteria analysis derived from the disciplines of economics and management sciences. Until now, the AHP method has not been used in the analysis of the revitalisation process, which confirms the innovative character of the conducted research.

- Challenges of Urban Garden Initiatives for Food Security in Kuala Lumpur,
Malaysia
Abstract: Sustainable urban farming is a strategy to improve food availability and food access, and to support food security for the urban population in Malaysia. However, the development of these activities has been affected by several constraints. This article aims to identify the challenges faced by urban farmers in Kuala Lumpur. The challenges of practicing urban gardening were categorised into five groups (technical, resource-related, economic, social and environmental factors). Data were collected via a questionnaire survey distributed to 106 urban farming practitioners from 17 urban gardens in Kuala Lumpur and were analysed using descriptive analysis by tabulating the frequency and percentage. The result showed that highly fluctuating weather, problems with access to available land and financial problems were the main challenges faced by urban farmers in Kuala Lumpur. Furthermore, difficulty in access to a financial institution, lack of commitment and the increased number of pests were also the problems faced by the urban garden. Availability of technical factors is the least issue in this study. Correlation analysis was used to determine the relationship between the challenges of urban gardens and socio-demographics. The result showed that there was a weak correlation between technical factors of educational level (r = 0.225) and race (r = 0.210), respectively, as well as between race and social factor (r = 0.201), while there was a moderate correlation between age and environment factor (r = −0.410). There is a need for further work, and comprehensive research should be conducted to capture what actions can be taken to create a policy-making space for urban farmers.

- Life Cycle Sustainability Assessment of Decentralised Composting of
Bio-Waste: A Case Study of The Łódź Agglomeration (Poland)
Abstract: The study examines the concept of decentralised composting of bio-waste as an alternative approach to current waste management practices, using the Łódź Agglomeration (Poland) as an exemplary case study. Consequently, the aim of the presented research is to compare and discuss the sustainability of the functioning bio- waste management system (status quo) against an alternative solution based on decentralised composting. Combined application of process-based life cycle assessment (LCA) and life cycle cost analysis (LCCA) was selected as the methodology to compare the sustainability framework for the waste management practices under analysis. The study has made it clear that decentralised composting of bio-waste offers broader environmental, economic and social benefits, albeit with the level of that benefit being very much correlated with the type of local government area (commune or in Polish gmina). Regardless of the impact category, rural and urban–rural gminas achieved the greatest savings, reaching >90%, and thus are seen to offer the greatest potential for decentralised composting to be put into effect, on the basis of household/backyard composting. In consequence, decentralised composting can constitute a fundamental form of bio-waste management in 20 out of the 28 gminas of the Łódź Agglomeration. The results obtained from the research facilitate the implementation and wider utilisation of decentralised composting, as an important element of the transition to a circular economy, where bio-waste is concerned.

- Changes in Industry and Services Sectors in Poland during the COVID-19
Pandemic
Abstract: In 2020, the World Health Organization announced the global COVID-19 pandemic, which was followed by unprecedented constraints on society and the economy. The restrictions imposed had an impact on the transformation in industry and services sectors. The pandemic, however, affected particular industry sections and types of services to a different degree. Overall, the industry sector is assumed to have been less affected by the crisis, because the government restrictions did not embrace industrial production for the most part. Services faced a different situation; some of them were not provided due to top-down decisions. Therefore, the vulnerability of industry and services to such a strong external impact varies. The article aims to identify the degree and trends in changes in industry and services sectors during the COVID-19 pandemic and to determine the regularities stemming from a different degree of vulnerability of both sectors to such a powerful external stimulus. The study examines changes occurring in different industries and types of services (by the Polish Classification of Economic Activity/NACE 2.0) by way of statistical indicator analysis and using Statistics Poland and Eurostat data.The conducted analysis of the COVID-19 pandemic influence on the industry and services sector leads to the conclusions that its impact on the industry sector was very time-limited—a sharp fall in gross value added in industry occurred mainly in the second quarter of 2020. The pandemic had a modest effect on industry employment, primarily as a result of anti-crisis shields and the will to maintain the potential of labour resources. In the services sector, accommodation and food services suffered the most. The significant falls were noted in the transport section as well as cultural, sports and personal services. Business services which were transferred to the Internet and were provided online ended up the most resilient. The ultimate winner of the pandemic is ICT services, especially electronic ones, which have replaced, wherever possible, traditional types of services.

- Environmental Social Science and Urban Environment Management: A Review of
Pathways Linking Policies and Planning to Citizens Living by the River
Abstract: Urban environment management (UEM) and environmental social science (ESS) are two interconnected approaches that show significant potential for creating more sustainable and liveable cities. Their research has, however, been mainly disjointed, which may be because planning and policy have placed more emphasis on UEM than ESS at the same time. This research examined ESS in terms of the quality of life (QOL) criteria and sense of place (SOP) of citizens living by the river with the UEM intervention in the form of policies and programmes. The effects of fieldwork in the form of specialised and spatial interviews are presented in this research, which is usually ignored in the literature review of this type of analysis. The study aims to fill the current gap in this field in three European capitals by providing a reflective methodological account of fieldwork and the ‘elite interviewing’ approach. This paper produces a distinct form of the localisation of the research and sampling techniques and is as new, interactive and developing as possible. The results of the present study are underpinned by the conceptual model of research, which supports the main aim of this analysis and tries to examine the components of research in a new perspective. The findings highlighted that maintaining and strengthening ESS for citizens living next to rivers require innovative UEM, which uses urban creativity in the field of goals, urban settlements, strategies and management solutions to provide the base for increasing the liveability of the city and improving the quality of urban life.

- Geotourism Potential of Show Caves in Poland
Abstract: In the modern world, tourism is a very dynamically growing industry with significant impact on the economic prosperity of many regions or even countries. The paper presents the geotourism potential of the 12 show (commercial) caves in Poland before and during the current pandemic time. Survey results demonstrate that caves are major geotourist attractions. In 2019, they were visited by a total of almost 950,000 people. The attendance might have exceeded even a million if the popular Mroźna Cave in the Tatras had not been temporarily closed to visitors due to a rockfall in winter period 2018/2019. In 2020, all the show caves combined were visited by a more than 390,000 people, which amounted to about 41% of the total attendance recorded for 2019. The most visited cave proved to be Smocza Jama (Dragon's Den) in the centre of Kraków, which recorded almost 422,000 visitors in 2019. A preliminary assessment of the attractiveness of the caves as geosites is given. The most attractive caves as geosites were identified as: Bear Cave, Upper Wierzchowska Cave, and Bat Cave. It is possible to confidently assert that the celebration of the International Year of Caves and Karst (IYCK) in 2021–2022 will increase interest in caves and translate into a revival of cave tourism.

- Causes and Course of Climate Change and Its Hydrological Consequences in
the Greater Poland Region in 1951–2020
Abstract: The paper presents effects of changes in climatic elements in the Greater Poland region (Poland), their causes and consequences for shaping the water balance of this area, copying with the most severe water deficit in Poland. The study period covers 70 years (1951–2020). The research identified an abrupt and significant change in the climate of Greater Poland, which started between 1987 and 1989, concerning not only air temperature but also a wider spectrum of climatic elements. The change in the state of the climate, which covers the entire Atlantic-Eurasian circulation sector, results from a sudden change in the macro-circulation conditions in the middle troposphere (500 hPa). The reason for the change in the mid-tropospheric circulation is an equally abrupt and simultaneous change in the intensity of the ocean heat transport by the North Atlantic thermohaline circulation (NA THC). Climate change observed in Greater Poland is manifested in an increase in sunshine duration (SD) and air temperature, a decrease in relative humidity, a change in the cloud structure, and an increase in the degree of sky coverage. The main, physical reason for an increase in air temperature is a rapid and strong increase in SD in the warm half-years, which began after 1988, and a significant increase in the frequency of positive North Atlantic Oscillation (NAO) phases in winters. The ongoing climate change entails various effects, among which the most important is considered to be hydrological consequences. The water balance of Greater Poland is becoming increasingly unfavourable, mainly as a result of a rapid increase in field evaporation.
