The purpose of the article is to present the evolution of the economic space in the modern metropolis. The paper systematizes the most important changes of that space, in particular those expressed in the emergence of new areas and places of economic activity. To present this evolution, three axes illustrating various types of activity are used, constituting the contemporary pillars of metropolis development: production and technology, control and information, and consumption and culture.

Public space of the post-modern epoch is a conglomerate or blend of discontinuous functions, a collection of loosely connected fragments, increasingly more frequently unrelated to a city. People compose for themselves their own town from individual trajectories that are outlined by means of motor roads. Neo-liberal logic of city development recognizes the rule of spontaneity wherever the interest of big capital groups dominates, pushing onto the sidelines the more important task of contemporary urban planning – the protection and development of public spaces. Due to the crisis it is undergoing at present (commercial pressure), the efforts are taken to regain its social and spatial significance. The purpose of these transformations is bonding public spaces with broader surroundings (with open terrains, waterside zones, promenades, playgrounds, etc). Such recomposition is part of a regeneration process that unites the city and reconstructs the identity of the place where relationships of inhabitants with their urban environment were not completely abandoned.
It has been substantiated that the increase in the concentration of heavy metals in the environment has especially aggravated in the conditions of military operations on the territory of Ukraine. The use of woody plants for the purposes of phytoremediation is one of the most effective options for optimising the state of the environment in urban ecosystems, regardless of the nature and source of contamination by metallic elements, which is of significant relevance in the conditions of post-war environmental restoration of Ukraine. The purpose of the study is to explore the peculiarities of some heavy metals accumulation by the assimilation apparatuses of the black locust (Robinia pseudoacacia L.) plants growing in the recreational areas of the city of Dnipro in order to further optimise tree plantings with the aim of improving the environment. The content of heavy metal elements (Cu, Zn, Pb, and Cd) in the biomass of the Robinia pseudoacacia L. leaves and in the soils of Dnipro recreation areas has been determined. The intensity of the accumulation of heavy metals in the phytomass of the Robinia pseudoacacia L. represents the following sequence Zn > Cu > Pb > Cd, which demonstrates a more intense absorption and accumulation in the phytomass of the leafy fraction of Zn and Cu in the phytomass of the deciduous fraction, and less significant of Pb and Cd. With the help of geo-information systems, cartographic material has been developed. It demonstrates the concentration gradient of Pb, Cu, Cd, and Zn in the assimilation organs of the black locust plants in the city of Dnipro recreational areas. Based on the cartographic analysis, it has been proved that the general condition of the soils in the recreation areas of Dnipro is characterised by significant disproportions in the level of pollution. The maps show the existing potential of the accumulative capacity of Robinia pseudoacacia L. to deposit Pb, Cu, Cd, and Zn, which allows for additional city functional zoning by considering phytoremediation functions of the existing and planned green spaces.
This article is an attempt to compile the existing knowledge from many fields about the aesthetics of Polish urban space: the conditions of its creation, its perception, and the problems it currently faces, of which a pressure for absolute aestheticisation appears to be the most dangerous. Through a multidisciplinary literature review as well as an analysis of public discourse and interviews with experts, the author attempts to answer the question about why there is such a large discrepancy in the assessment of the aesthetics of urban spaces in Poland, as well as how this is influenced by cultural, legal, administrative, and historical conditions.
This paper examines the impact of the implementation of participatory budget (PB) projects on the development and creation of public spaces in the city. The first part of the paper describes the main assumptions and models of participatory budgeting as well as the legal basis and rules of PB implementation and financing in Poland. In the second part, those are confronted with the implementation of PB (civic and green) in Lublin in 2015-2019. In the third one, detailed analysis of the PB rounds 2015-2017 show that 86% of investment projects submitted and 87% of projects selected for implementation were directly associated with activities in public space. Furthermore, the spatial distribution and thematic scope of those investments in 27 districts of Lublin in relation to 10 categories selected by the authors as well as the motivation and activity of residents of individual districts in applying for projects were presented. The fourth part shows the changes in Lublin’s public spaces caused by the implementation of PB projects and Lublin’s experience in relation to other cities in Poland. The summary includes recommendations on how to effectively implement BP to create a high quality public space in cities. Three aspects are distinguished: 1) organizational and procedural; 2) mobilisation of the stakeholders and 3) implementation of projects.

The paper assesses the state and conditions of the development of Polish cities in the context of processes and issues that occur in the cities of highly developed European countries. The latter, particularly those located at the very core of Europe, enter a new phase of development. Interconnected through networks of various links, the countries form economically integrated urban spaces characterised by the highest competitive potential in the global economy, at the same time losing their nature of self-contained, self-standing socio-economic systems. The author describes the underlying processes, pointing to the fact that they are visible in Poland, but rather not yet advanced. Poland is a country of retarded urbanisation with insufficiently competitive in Europe economic base of cities, quite well-developed human capital, but with mediocre social capital and low quality urban space. The main challenges of Polish cities` development are outlined from the perspective of European integration, including a discussion of the most common visions of European cities of the 21st century, in the context of developmental aims and ways to attain them.
