Introduction. The problem of solid household waste management, analyzed in the context of sustainable development, is relevant both in Russia and worldwide. On the one hand, it deals with vast legitimate and illegitimate landfills, polluting the environment. On the other hand, it deals with the depletion of natural resources and the potential usability of latent reserves of recyclable waste. It is inefficient to accumulate mixed waste and build recycling capacities, since they are accompanied by atmospheric pollutions. Separate collection of waste has a great potential. According to the estimates, Russia’s waste management system will move to a new level when local waste management companies come into operation. This new level will ensure environmental protection and higher standards of living. However, the intersectoral problem of separate waste collection cannot be solved by local waste management operators. This problem deals with urban development patterns and urban economies of the RF subjects, as well as the Russian industries, that use recyclable materials. Materials and methods. The co-authors have applied the system analysis of the research literature, statistical data and regulatory documents, as well as process modeling. Results. The co-authors have analyzed the engineering model of separate waste collection, implemented by residents of multi-family homes within the framework of the “nature – economic activities – nature” pattern. The accumulation of hazardous and oversized waste is organized as the separate subsystems of the waste management system implemented by the residents of a multi-family home. Conclusions. The co-authors propose to modify the system of household waste management to prevent the over-accumulation of substantial amounts of mixed household waste in waste containers near residential houses and in waste collection rooms. The introduction of ecologically friendly innovations is needed at each stage of the life cycle of any product.
Introduction. A promising direction of nature management, which allows avoiding the degradation of the biosphere, is the implementation of economic and other activities with minimal impact on nature. The state of health of the population is influenced by a complex of environmental factors. The load of atmospheric air is perceived by the respiratory organs, vision, and the skin. Water influences in the form of precipitation, both drinking and recreational. The direct effect of soil on human health occurs through direct contact with the skin, inhalation and oral intake into the body. Green spaces have a significant impact on the quality of urbanized soil, water and air, as well as the health of residents. The main aspect of environmental protection and maintaining a favorable microclimate in settlements is the preservation and recreation of the “green” fund. Materials and methods. Systematic analysis of scientific literature, statistical data, regulatory documents. Results. The dependence of Russians on the influence of sanitary and hygienic factors of the environment is shown. The dynamics of the indicator “green spaces” in the urban environment quality index for the group “largest cities” is considered. On the example of St. Petersburg, the satisfaction of residents with the sphere of landscaping the territories of city districts is shown. It is proposed to conditionally divide the main problems of the development of “green” infrastructure into groups. The conceptual principles that constitute the methodological basis for the creation of a “green” frame of a settlement have been determined. Formed a group of criteria for assessing the “green” infrastructure, which are indicators of technical progressivity and social significance, with predictive ability and consistency. Conclusions. The necessary and sufficient amount of green spaces, normalizing the quality of the urban environment, can have a positive impact on the physical and mental health of residents. Strategic planning for the development of the “green” infrastructure of the settlement, ensuring the viability of the green frame, should take into account all its elements and include landscaping of land plots adjacent to the territories of multi-family dwelling.
Introduction. People want effective management and balanced development of urbanised systems. In a comprehensive social, economic and environmental research of human living conditions in the city, various kinds of sociological surveys of the population are applied and foresight sessions are held with subject matter experts to analyse the existing level of safety and comfort of residence. However, in the context of growing urbanized systems, there is an acute shortage of new methods, ways and tools of knowing them for the purpose of effective management and balanced development. Materials and methods. The article presents aspects of the methodology for extracting and structuring knowledge of urban public green spaces in cities. The work is based on the paradigms of ontological engineering and knowledge management. Results. Ontological engineering as a theory and methodology for developing ontologies is actively developing. However, the main success lies in the field of knowledge formalization technology, while the methodology for extracting and structuring knowledge is still under development. The problem of meaningful analysis of the subject area remains open, the relevance of research of which is confirmed by sustainable development goal 11, target 11.7: “by 2030 provide universal access to safe, available and inclusive green spaces and public spaces, especially for women amd children, older and disabled people”. The article describes the process of developing a taxonomy of expert knowledge about urban public green spaces in city. The taxonomy includes classes, subclasses, properties for subclasses and options for properties. Conclusions. The results of the conceptualisation of knowledge of the subject can be used as elements in the construction of the knowledge graph framework. With appropriate refinement, the taxonomy can be in demand for scientific research, design of innovative services and intelligent systems used in urban planning and urban economy.
The urbanization process is accompanied by the growth of cities and an increase in their population. Modern cities are highly complex systems that comprise material and non-material elements of life of urban residents. The development of the urban economy shapes the demand for housing and utility services. Consumer requirements have changed over the years. The aspect of environmental protection and rational use of natural resources from the standpoint of the biosphere approach is to ensure the environmental safety of residential areas in urbanized territories. The analysis of statistical information and analytical reviews, available in the open-access sources, is carried out in the context of (1) the housing construction in the subjects of the Russian Federation, (2) ensuring the quality of the urban environment in the regions, (3) satisfaction of the local population with the living conditions in a quarter and in a city. The emphasis is placed on the volume and pace of construction of residential apartment buildings in the Russian cities from 2019 to 2021, consumer requirements for apartments, houses, and landscaping. The ecological resource of an urbanized territory represents the rate and quality of the housing construction, including urban planning, volumetric planning, constructive and technological solutions, as well as the current state of the urban economy, including the volume and quality of housing and utility services provided to the population. A system of parameters for calculating the ecological resource of residential areas is proposed for discussion, including the estimated indicators of the results of urban planning activities at the stages of the life cycle of a territory and the underground, surface and above-surface facilities that it accommodates. Macro-level design includes the accommodation and construction of permanent construction facilities, linear facilities and their infrastructure; the landscaping of the territory, as an element of the “green” urban framework; a system for handling solid municipal, bulky and hazardous waste. The micro-design is an ecological resource at the level of structural elements of a residential zone, it encompasses a residential area, a micro-district, a block, a complex.
Cities are growing. The ecology is deteriorating. There is a lot of waste in the cities. It is very important to collect waste separately. Who decides what's best? I think we need to change the attitude to waste. There are many different containers to be placed in waste collection areas. It's a lot of work for the city.
