This paper is based on the results of an extensive (840-page) report of the Committee on National Spatial Development of the Polish Academy of Sciences, entitled Studies on Spatial Chaos (edited by A. Kowalewski, T, Markowski and P. Śleszyński—Studia KPZK PAN, vol. 182, Warsaw 2018—in Polish). Its aim was to conduct a comprehensive and detailed study on the problem of spatial chaos (spatial disorder), including an estimate of economic costs in Poland. For this purpose, literature was queried (articles and reports, etc.) and special analyses were prepared for this purpose. The total annual costs of spatial chaos were estimated at not less than 20 billion euros per year. The conclusions also proposed solutions and suggestions (for the government and local governments), which may reduce the acute costs of spatial chaos in society and economy.

The spatial management system in Poland struggles with serious costs as a consequence of local planning. The problem is the lack of appropriate value capturing mechanisms and cost compensation for municipalities, along with significant burdens. Private property is subject to special protection, but the public good is less valued. The article attempts to assess the situation in Poland, recalling also the experiences of spatial management systems from other European countries. It combines legal, economic, and geographical perspectives. The specific objectives were demonstration of geographical (interregional and functional) regularities related to the economic (financial) consequences of adopting local plans and identification of financial effects resulting from the implementation of local plans in communes, i.e., in particular, their size, structure of revenues (income), and expenditures, in relations with the budgets of municipalities and the population living in communes. First, the determinants of spatial policy were defined in the context of institutional economics and the real estate market. Then, a unique database of forecasted and realized budgetary revenues and expenditures of 2477 communes in Poland related to spatial development (infrastructure construction, land transformation, purchase, etc.) was analyzed statistically. Additionally, for five selected communes of different functional types, this issue was examined in detail. It has been shown that municipalities do not derive adequate income from spatial development, and improper policy of local self-governments results in heavy burdens, threatening to disturb their financial balance. The formulated conclusions regarding the legal, economic, and spatial mechanisms may contribute to building tools (instruments) for more effective spatial management in various countries.

The paper aims to determine the role and formula of investments in renewable energy sources in Poland’s concepts of local spatial policies. It analyses 12,777 planning documents of local spatial policy (these are resolutions adopted by municipalities—in Poland there are two types of these instruments: studies of spatial development conditions and directions and local spatial development plans) in Poland enacted in 2005–2020. On this basis, local concepts were classified and related to the geographical and functional characteristics of municipalities. Poland is an interesting case study in this respect, providing a good reference point for broader international considerations. It was found that only 58.4% of Polish municipalities include renewable energy sources in their spatial policy concept. These are definitely more often urbanised municipalities. The degree of approach to renewable energy sources is also determined by the location of the municipality in the given province. The authors diagnose serious weaknesses in the Polish spatial planning system, consisting in the lack of skilful implementation of renewable energy sources into it. This is one of the reasons for the weaker development of renewable energy sources in the country. The authors consider as an innovative element of the research the analysis of the content of all spatial policy instruments in a given country, from the perspective of renewable energy sources, including proposing a way to verify these instruments.

The article presents an analysis of geographical-settlement and legal-planning conditions for the development of Poland’s distributed generation. The choice of this country is important and interesting due to the highly dispersed settlement, which may be a factor stimulating the development of this type of energy systems. For this reason, the analysis can be a model for other countries and regions, indicating ways to analyze and evaluate settlement and planning conditions for the development of renewable and distributed energy. At the same time, Poland is struggling with a severe crisis of spatial planning. By analysing these opportunities and threats, empirical analyses try to indicate regularities in this respect in Poland’s regions in a detailed approach to communes and detailed legal and planning conditions. The conclusions emphasise the usefulness of distributed generation development for peripheral and sparsely populated areas of Europe and other parts of the world and appropriate directions of changes in spatial development law.

The article aims to compare the local tools of Ukrainian and Polish spatial policy. It includes legal solutions (with a particular emphasis on the basics of development restrictions) and problems related to their application diagnosed in the literature on the subject. Based on the analysis of the spatial management systems of both countries, the similarities and differences were determined, referring them to the international discussion and suggesting directions for further research (on the spatial management systems of Central and Eastern European countries). Ukraine and Poland were selected for analysis in terms of similarities (partially similar historical conditions, location) and differences (status of a European Union Member State, spatial planning traditions).

The aim of this study was to identify how the literature analyzes (identifies, evaluates, forecasts, etc.) the relationship between health issues and urban policy in relation to the COVID-19 pandemic. Four main levels were identified in these cases: (1) direct demands for changes in health care, (2) social issues, (3) spatial organization and (4) redefining the tasks of public authority in the face of identified challenges. The basic working method used in the study assumed a critical analysis of the literature on the subject. The time scope of the search covered articles from January 2020 to the end of August 2021 (thus covering the period of three pandemic waves). Combinations of keywords in the titles were used to search for articles. The health perspective pointed to the need for urban policies to develop a balance between health and economic costs and for coordination between different professionals/areas. A prerequisite for such a balance in cities is the carrying out of social and spatial analyses. These should illustrate the diversity of the social situations in individual cities (and more broadly in urban areas, including, sometimes, large suburbs) and the diversity’s relationship (both in terms of causes and consequences) to the severity of pandemics and other health threats.

This study was aimed at investigating the physicochemical and microbiological changes that took place during the ageing process of spent bleaching earth in the presence of autochthonous microorganisms. Research material included fresh spent bleaching earth (SBE0) and the same material after 3 years of storage at the constant temperature of 20 °C, without aeration and moistening (SBE3). Changes in the chemical composition of analysed waste material were observed during its ageing process point to a spontaneous bioconversion of fat substance towards formation and/or release of free saturated fatty acids C16:0 and C18:0 (14.3 g 100 g−1 D.M.), triterpenes (8.48 g 100 g−1 D.M.), cholesterol (3.29 g 100 g−1 D.M.), small quantities of carbohydrates and esters (0.80 g 100 g−1 D.M.). This process was accompanied by other changes in physicochemical parameters of the waste material, such as colour, odour and viscosity, decrease in fat content from 28.27 to 24.6 % and that of soluble forms of metals (Mo, Cu, Fe, Zn, Ni, Cr and Mn), ranging from 25 to 75 %, and an increase in pH, from 3.85 to 4.2. At the same time, changes in the microbial consortium were observed.
