A new vision of the global needs of mankind is embodied in the concept of sustainable development, which means meeting the needs of the current generation without compromising the ability to meet their needs by future generations. Today, more than half of the world population lives in cities, the development of which is influenced by many interdependent factors, so there is a need for a clear and holistic approach to sustainable urban development. The aim of this paper is to study urban infrastructure in the aspect of its greening as an important component of the sustainable development system of the city. The paper analyzes the academic literature on the problem of greening urban infrastructure as the basis for sustainable development of the city. The determination of the main elements of green infrastructure and technologies in the field of green infrastructure in foreign countries has been carried out. Particularly significant action strategies for cities have been identified as part of a sustainable development policy.

Abstract Protected areas are the key elements of the green infrastructure and environmental city frame that provide variety of ecosystem services to the people as well as serve as the centers of investment attraction. The total area of the protected lands of Khabarovsk is 583.57 ha (1.5% of the city area): 5 protected ones of regional significance, 24 areas of local significance. There are 117 species observed in the dendroflora of all protected areas, which is relatively close to the natural biodiversity indicator. The reserve for expanding the protected areas network in Khabarovsk is mainly represented by the lands of the Russian Ministry of Defense, floodplain lands, the adjacent areas to the water protection zones of small rivers in the city, and ecologically restored technogenic sites. In addition to the forest type areas this will permit to create water and meadow-marsh protected plots, which meets the representativeness criteria of the natural ecosystems of the Amur River Region. The case study of a protected area called Orekhovaya Sopka, allows seeing that keeping record of the ecosystem services increases both the economic and the environmental values of the territories. The results may be applied in: municipal management.

Abstract The main criterion for sustainable development in the world ultimately comes down to the ratio of disturbed and undisturbed areas within certain boundaries and compliance with particular conditions. These conditions can be met by considering the city area together with its suburbs. The presence of a suburban area and its characteristics depend on the stage of urbanization of the area. Newly-developed cities, being in the first stage of urbanization, have a sufficient amount of open space in both urban and suburban areas. This is an advantage in shaping sustainable development over the old-developed cities, which are in the second and third stages of urbanization. In these stages, urban agglomerations are formed, resulting in the shrinkage and sometimes complete disappearance of suburban areas. At the same time, industrial, transport and military facilities that have lost their functions in the process of de-industrialization, the downsizing of the urban kernel and the formation of a “secondary” free space, are being rehabilitated or completely eliminated. These activities are labour-intensive and costly, but they do help to increase some of the available space within the city and improve the environmental situation in the city.

The goal of the study is to determine the actual areas and the geographical distri- bution of Urban Green Spaces (UGS) in Kyiv; compile and analyse the ratings of the city administrative districts by key UGS indicators and substantiate the level of comfortable living in each district according to the concept of a green compact city. The goal stems from the announcement of an official strategy of transforming Kyiv into a comfortable compact city with an attractive green infrastructure. To achieve this goal, we have calculated a number of major indicators of the modern green infrastructure of Kyiv in all ten city districts. According to the method we developed, we analysed the drawings of the urban development master plan and regulatory documents, and conducted a field survey of significant UGS sites in Kyiv. The data obtained were used to make a UGS map of Kyiv and other thematic maps. For the most accurate calculation of key UGS indicators, we processed several thousand contours in Kyiv’s cartographic base. The sizes of Urban Protected Areas (UPA) were found separately, and their share in the total city territory and of each district (Conservation Coefficients) was determined. In so doing, UPA distribution was found to be very irregular, with a total area of 174.9 km2, or about 21.2% of that of Ukraine’s capital. We analysed the ratio of the city population and the areas of green spaces in each Kyiv district. To identify districts with a different UGS coverage, we calculated the Greenness Coefficients (GC) and compiled a rating of Kyiv districts by their level of greenness, using the Greenness Coefficients Index. Significant GC variations in different city districts were substantiated. In contrast to previous studies, we calculated the provision of Kyiv residents with green zones of not merely common usage, but also with those of all other kinds, including UPA. We also calculated the Green space provision per person and compiled ratings of Kyiv districts by the Green Space Provision Index. The results were presented on a relevant map. Based on calculating the share of protected areas in the total UGS area, we found the ratings of Kyiv districts by the Green space legally protected Index. Wherein, we found significant variations among the districts by the ratio of protected areas and green spaces deprived of any legal protection. This increases their vulnerability to projected development attempts. We calculated the Integral Green Space Index (GSI) based on processing all significant UGS indicators of Kyiv. GSI allows for an integral assessment of the condition of the Urban Green Infrastructure (UGI) in Kyiv, and it is the key criterion of its compliance with modern requirements to an ideal compact city. Holosiivskyi District received the highest GSI rating. It is uniformly replete with UGS, which are provided for quality recreation and, at the same time, are protected by environmental legislation. Solomianskyi District received the lowest rating, and almost all the elements of its existing UGI require a cardinal optimisation. As a whole, the indicators we calculated can create an illusion of adequate provision of Kyiv with UGS. Actually, they are distributed very irregularly in the majority of districts. The results of our study are indicative of the presence of many challenging locations that require an extension of existing UGS and the development of new ones pursuant to the principles of compact city planning. Since UGI planning depends on the implementation of the Urban Development Master Plan, it makes sense to include the Green Space Index to the key indicators of the Kyiv Development Strategy. The draft new City General Plan should also be refined with account of the above-mentioned problems.

The formation of the ecological framework of the city determines its viability in general as a modern settlement structure that meets the requirements of sustainable development. In this case, the ecological framework of the city becomes the basis that will be able to form a single ecosystem of the city and establish a format of connections between its various elements. The purpose of the article was to determine the role of the settlement area in the formation of the ecological framework of a large city. This article identifies the role of residential areas in the formation of the ecological framework of the city. The author analyzes the concept of "ecological framework" and its compliance with the peculiarities of the urban structure. It was found that the ecological framework is mainly interpreted as a natural framework. In an urban environment, this leads to certain inconsistencies. The city also has its own spatial framework, which includes a number of properties and characteristics. Therefore, the author proposes to consider the ecological framework of large cities as a system of interaction of natural and urban frameworks. Establishing the right relationship between them will ensure compliance with the level of environmental safety in the city and its sustainable development. It was established that there is no understanding of the concept of ecological framework in the context of urbanization. Most authors consider the ecological framework exclusively as a natural framework of the territory, which is relevant for large areas outside large cities. It is proposed to take into account the peculiarities of the existence and development of the urban organism, which has its own structure, its own spatial framework. It is determined that the urban framework consists of elements of different functions, which are interconnected by a network of communications. All elements create a certain load on the natural structure of the territory (natural framework). It is proposed to consider the ecological framework of a large city as a combination of natural and urban framework. It is their rational combination that will help to improve the environmental situation as a whole and will meet the conditions of sustainable development of the city. Keywords: ecological framework, settlement territory, natural framework, urbanization, ecological stabilization, ecological knots, ecological corridors.

The article examines the process of degradation of the landscape-ecological framework of the city due to the dominance of the human-centered approach to the urban recreational areas’ organization. Using the methods of cartographic analysis, full-scale photographic recording, synthesis and abstraction, a study of the recreational territories of Kharkov city was carried out and three main types of recreational objects development were identified: small recreational objects (up to 10 hectares), which completely lost the opportunity for sustainable development, self-creation and are completely dependent from human withdrawal; medium-sized district and city parks, which are being reorganized into urban parks and amusement parks with a high level of recreational load; large elements of the landscape-ecological framework, which are degrading due to the complete absence of the recreational organization of the territory. It was also determined that the main reasons for the loss of sustainable development by recreational facilities are: lack of a comprehensive strategy of the system of landscape and recreational areas development for the city; making situational decisions about the reconstruction of recreational facilities in the city; inconsistency of the park’s type within its place in the structure of the landscape-ecological framework of the city; preference for the organization of park areas with high recreational loads; irregular organization of recreational areas in the city. The main steps of the strategy for the integrated development of the city landscape-recreational system are proposed, which are as follows: determining the level of value of a recreational facility in the structure of the city landscape-ecological framework, assessing the sustainability of a recreational facility development at the present stage, predicting the types of recreational organization of territories, the prospective level of recreational load, and the level of domestication of the object in order to preserve its sustainable development in the future.

The increasing popularity of street redesigns highlights the intense competition for street space between their different users. More and more cities around the world mention in their planning documents their intention to rebalance streets in favor of active transportation, transit, and green infrastructure. However, few efforts have managed to formalize quantifiable measurements of the balance between the different users and usages of the street. This paper proposes a method to assess the balance between the three fundamental dimensions of the street—the link, the place, and the environment—as well as a method to assess the adequation between supply and demand for the link dimension at the corridor level. A series of open and government georeferenced datasets were integrated to determine the detailed allocation of street space for 11 boroughs of the city of Montréal, Canada. Travel survey data from the 2013 Origine-Destination survey was used to model different demand profiles on these streets. The three dimensions of the street were found to be most unbalanced in the central boroughs of the city, which are also the most dense and touristic neighborhoods. A discrepancy between supply and demand for transit users and cyclists was also observed across the study area. This highlights the potential of using a distributive justice framework to approach the question of the fair distribution of street space in an urban context.

This paper explores how design in the public realm can integrate city data to help disseminate the information embedded within it and provide urban opportunities for knowledge exchange. The hypothesis is that such art and design practices in public spaces, as places of knowledge exchange, may enable more sustainable communities and cities through the visualization of data. To achieve this, we developed a methodology to compare various design approaches for integrating three main elements in public-space design projects: city data, specific issues of sustainability, and varying methods for activating the data. To test this methodology, we applied it to a pedogeological project where students were required to render city data visible. We analyze the proposals presented by the young designers to understand their approaches to design, data, and education. We study how they “educate” and “dialogue” with the community about sustainable issues. Specifically, the research attempts to answer the following questions: (1) How can we use data in the design of public spaces as a means for sustainability knowledge exchange in the city? (2) How can community-based design contribute to innovative data collection and dissemination for advancing sustainability in the city? (3) What are the overlaps between the projects’ intended impacts and the 17 United Nations Sustainable Development Goals (SDGs)? Our findings suggest that there is a need for such creative practices, as they make information available to the community, using unconventional methods. Furthermore, more research is needed to better understand the short- and long-term outcomes of these works in the public realm.

In recent years, rainfall-induced waterlogging has become a common hazard in the highly urbanized coastal city of Chattogram, Bangladesh, resulting in a high magnitude of property damage and economic loss. Therefore, the primary objective of this research was to prepare a waterlogging inventory map and understand the spatial variations of the risk by means of hazard intensity, exposure, and vulnerability of waterlogging. In this research, the inventory map and factors influencing waterlogging hazards were determined from a participatory survey, and other spatial data, including land elevation, population, and structural data, were collected from secondary sources. The analytical hierarchy process was applied to measure the hazard intensity, and the exposure and vulnerability were estimated by overlaying the spatial data onto the hazard intensity map. A total of 58 locations were identified as waterlogging affected, which covered ~8.42% of the city area. We showed that ~3.03% of the city area was greatly vulnerable to waterlogging in terms of their social, infrastructure, critical facilities, economic, and environmental vulnerabilities. The obtained waterlogging risk index map suggested that ~2.71% of the study area was at very high risk, followed by moderate (~0.15%), low (~3.89%), and very low (~1.67%). The risk analysis presented in this study was a simple method that can be applied to assess the relative risk of waterlogging in different regions, and the results were applicable to the prevention and mitigation of waterlogging for Chattogram City.
