The relevance of the study is determined by the identified shortage of the urban environment in Russia, namely those types of buildings that meet modern requirements. In large cities, the only way to change this situation is redevelopment. This article considers options for stimulating the development of urban areas and optimization of their use through redevelopment. The definitions of the concepts of redevelopment, renovation, gentrification, revitalization are delimited. The classification of types of programs according to the level of management is performed. The advantages and disadvantages of the redevelopment process are presented. Based on the analysis of the regulatory and legal framework, the authors revealed that the concept of “redevelopment” is not defined in any way in it. The practical experience of implementing redevelopment projects and programs in Russia, including development projects of the main industrial zones of the city of Moscow, which are inextricably linked with the strategic development of the constituent entities of the Russian Federation and the implementation of national projects, is analysed. Special attention is paid to the redevelopment project management issues, proposals are presented to increase the efficiency of program management based on the Japanese P2M project management standard. At the end of the study, the authors revealed the results achieved in the implementation of redevelopment projects and evaluated their effectiveness in terms of various indicators.

The article is devoted to the problem of ensuring environmental safety in the territories of large cities, primarily, to reducing atmospheric air pollution. The aim of the work was to build a comprehensive classification scheme of sources of pollutant emissions into the air basin of the territories of large cities, taking into account the climatic and physicalgeographical conditions of the considered urban areas. In the process of research, we solved the problem of identifying the basic principles of classification of air pollution sources based on the analysis of known methodological approaches with the subsequent improvement of calculation methods to justify the spatial distribution of residential areas, industrial areas, motorways, recreational areas, effective sanitary protective zones taking into account aerodynamics to remove polluted air outside the city territory. A generalized classification of sources of pollutant emissions into the environment is proposed, while the sources of air pollution in urban areas are classified according to the following main criteria: by origin, by aerodynamic parameters and by the nature of the direction of the emission plume, by spatial position and possible mobility, in terms of size in plan, in height of the spread of the emission plume, taking into account the height of the mouth of the source of the emission of pollutants above the level of the earth’s surface, in temperature of air-gas mixture, according to the mode of action.

Urbanization is accelerating worldwide. One of the negative effects of urbanization is the overloading of the city sewer system. To solve this problem, on-site storm water infiltration proves very promising due to its near natural characteristics and multiple effects on the drainage of stormwater runoff in urban areas. However, the judgment of whether a local area is appropriate to be drained in this way and which infiltration measures are optimal is rather complex and involves analysing a set of influential factors. This judgment depends on not only relevant theoretical considerations, but also a large amount of practical experience and the availability of relevant data, as well. Such a judgment is an unstructured problem and relates to changeable knowledge. To fulfill this task, the so-called expert system, or knowledge-based system, is introduced. One of the advantages of an expert system is that it provides automation of expert-level judgment. This is extremely helpful when an expert-level judgment is needed repeatedly for a large amount of cases, like in the planning of on-site stormwater infiltration systems for an entire city catchment. This paper describes a self-developed expert system tool for developing rule-based expert systems, as well as a case study: using an expert system for the selection of on-site storm water infiltration measures for the city of Chemnitz, Germany.

The city has proved to be the most successful form of human agglomeration and provides wide employment opportunities for its dwellers. As advances in robotics and artificial intelligence revive concerns about the impact of automation on jobs, a question looms: how will automation affect employment in cities? Here, we provide a comparative picture of the impact of automation across US urban areas. Small cities will undertake greater adjustments, such as worker displacement and job content substitutions. We demonstrate that large cities exhibit increased occupational and skill specialization due to increased abundance of managerial and technical professions. These occupations are not easily automatable, and, thus, reduce the potential impact of automation in large cities. Our results pass several robustness checks including potential errors in the estimation of occupational automation and subsampling of occupations. Our study provides the first empirical law connecting two societal forces: urban agglomeration and automation's impact on employment.

The article presents information about methods and technologies used in assessing the dynamics of urbanized territory, gives a brief description of them, and identifies advantages and disadvantages. The concept of geoinformation monitoring of an urbanized territory is formulated. To integrate heterogeneous and multiformat data and assess the dynamics of residential environmental management, a problem-oriented GIS for monitoring urbanized territories has been developed on the example of Ulan-Ude city (Republic of Buryatia). The functional structure of GIS, consisting of measuring, analytical and cartographic blocks, is presented, and the characteristics of each block are given. The planned basis of GIS is the topographic basis of three spatial levels: regional (1:200 000) for monitoring agglomerations and large cities; local (1:50 000, 1:100 000) to assess the dynamics of residential development of the territory; detailed (1:10 000, 1:25 000) to assess the dynamics of real estate and land plots. A digital terrain model is used as a high-altitude basis for the assessment of urbanized territories, which allows the assessment of morphometric parameters of the residential nature management system. The dynamics of the urbanized territory of Ulan-Ude was estimated using six time sections. The physical and geographical features of the urbanized territory development are determined, the map of the city dynamics for the entire period of residential development is compiled, and the forecast of the further development of the urbanized territory for background and local buildings is presented.

In the process of urbanization of large cities in different countries, there are similar problems of reorganization, involving the demolition of physically and morally obsolete buildings and structures, as well as the subsequent construction reorganization of the territories vacated or re-cut to the city. In the process of demolition of obsolete buildings and structures, as well as the construction of new buildings, inevitably significant amounts of waste and construction debris arise that should be recycled as much as possible into secondary building materials (to carry out the so-called «recycling» of waste). Types of construction reorganization of urban areas are divided into traditional, widely known and standardized (repair, reconstruction, restoration), and innovative, arising in the processes of reorganization of society. Among the innovative types of construction reorganization, renovation is currently the most relevant, meeting the need to renovate the dilapidated housing stock of cities. The article discusses the main types of construction waste generated during demolition and new construction, as well as the technologies used for recycling these wastes during the renovation of territories and pavements of large cities.

The city of Huancayo, like other intermediate cities in Latin America, faces problems of poorly planned land-use changes and a rapid dynamic of the urban land market. The scarce and outdated information on the urban territory impedes the adequate classification of urban areas, limiting the form of its intervention. The purpose of this research was the adoption of unassisted and mixed methods for the spatial classification of urban areas, considering the speculative land value, the proportion of urbanized land, and other geospatial variables. Among the data collection media, Multi-Spectral Imagery (MSI) from the Sentinel-2 satellite, the primary road system, and a sample of direct observation points, were used. The processed data were incorporated into georeferenced maps, to which urban limits and official slopes were added. During data processing, the K-Means algorithm was used, together with other machine learning and assisted judgment methods. As a result, an objective classification of urban areas was obtained, which differs from the existing planning.

Large cities still peak the interests of some Indonesian society. Big city development as the center of economic activity is a powerful pull for society, influencing high workforce from both inside and outside of the city, causing a strong current of urbanization. One main problem that always accompanies urban areas development is density population. Urbanization has caused a very rapid explosion in the city population; one implication is the clumping workforce in large Indonesian cities. The high number of people who choose to settle in the city increase the number of both legal and illegal settlements. In the high-density settlement, many houses are not liveable and irregular. The densely populated settlements find many houses unfit for habitation and irregular. The research aims to formulate the sustainability level of Urban communities, Lowokwaru District, Malang City using quantitative method through sustainability level calculation. Jatimulyo Urban Communities is measured by the sustainability criteria of density, diversity, mixed-use, and compactness to formulate the related sustainable urban spatial structure. Interpretation of the calculation results references similar research. The calculation result shows that Jatimulyo Urban Communities is included in the moderate sustainability level, where density is moderate (101.1-200 people/ha), has a moderate building density (20-40 buildings/ha), has a random diversity level (1.0) and an entropy index (0.51), and compactness is near perfect inequality (Gini Coefficient 0.99).

Introduction. In this paper, we analyze various methods of snow removal in urban areas and consider the most cost-effective and efficient solutions for snow removal and disposal using heat from sewage drains by means of stationary snow-melting points (SMP) in Nur-Sultan. In cooperation with Astana su Arnasy specialists, responsible for the operation of the city sewer system, as well as cleaning and disinfection of urban sewage drains, we reviewed the main advantages and disadvantages. Methods. The paper looks into the possibility of utilizing heat from sewage drains with the help of heat pumps. This method has been successfully tested at a sewage treatment plant and is currently used to heat auxiliary premises. The same principle can be applied in SMPs with a separate discharge of meltwater to the storm sewer. Results. Having studied the experience of using various methods for snow removal in urban areas, we find that snow removal with the use of sewage drains through the creation of special snow-melting complexes integrated with the city sewer system is the most promising method for Nur-Sultan since it allows for reducing costs, intensifying the process of snow melting, and eliminating the hazardous impact of meltwater on the environment. Conclusion. To ensure successful implementation and use of this snow removal method in Nur-Sultan, it is required to conduct a number of additional studies on the impact of sewage treatment plants on the technological processes, as well as to test options for separating sewage drains with the help of heat pumps, and, based on the studies conducted, to determine the final configuration of snow-melting complexes.

Abstract The study aims to present the structure and analyse the distribution of economic activities comprising the creative sector (covering 10 sections of PKD 2007 - the Polish Classification of Activities based on NACE rev. 2 - the Statistical Classification of Economic Activities in the European Community) of the Polish economy in the context of the potential basis for the formation of creative clusters in Poland. The study concentrates on the numbers of creative firms based in all 3,076 Polish gminas (306 urban gminas, 1,576 rural gminas and 597 urban-rural gminas; in the latter, 597 urban areas and 597 rural areas are considered separately). As found, most of the firms are involved in architectural and engineering activities; technical testing and analysis (M 71) and other professional, scientific and technical activities (M 74). It has also been established that some local incubators of the potential clusters of creative industries form eight distinct centres, the most prominent of which is the Warszawa centre. The identification of areas with higher concentrations of creative firms has demonstrated that in Poland, like in western countries, creative firms tend to locate in large cities (Warszawa, Kraków, Poznań, Wrocław and Tri-City) and in the regions around them.

<p>The renovation of the waterfronts, such as those in the main public spaces of large cities, started in 1970s. Core industries had found other places to develop far from the city; thereafter key areas fell out of use and into disrepair. As a consequence, a huge number of urban areas became in urgent need of renewal. However, urban design guidelines to regenerate these open spaces have significantly changed since then. The approach towards returning these parts of the city to its inhabitants has evolved from an emphasis on building new housing in the nineties, to considering the broader aspects of sustainability in the early years of the current century and finally to searching for the areas’ identity in more recent years. Therefore, currently this identity is one of the main aspects designers are looking for. At the same time, the sustainability of the waterfront areas may be achieved through the establishment of this place´s sense of identity. In order to do this, we assess three urban actions undertaken in Portland and Vancouver -False Creek North, South Waterfront and Southeast False Creek-. The article suggests that the interplay between urban design, sustainability and identity is becoming the new driver for the design of the waterfronts.</p>
