When looking for new uses for unused areas and buildings, it is essential to consider the context of the area, especially from the territorial-technical, spatial, socio-demographic, economic and urbanistic points of view. In order to find new uses for brownfields which will be sustainable in the long term, it is necessary to employ tools that enable holistic evaluation of the mutual relationship between brownfields and their surroundings so that the most suitable future use can be identified. In the present contribution the brownfields in the Liberec Region (Czech Republic), which is known for its ragged terrain and distinct industrial past, were subjected to this evaluation. Methodically, the contribution is based on principal component analysis and variance analysis (20 composed factors). The results indicate that in several cases apparent differences in the environment of neglected areas can be observed, whether based on previous use or between regenerated sites and sites falling into disrepair. The results of the performed tests show that the environment where brownfields occur differs in some cases, especially when comparing the past and present uses and the current state of their regeneration.

Re-reuse of regenerated brownfields: Lessons from an Eastern European post-industrial city2018 •
Brownfields constitute a substantial portion of the land area in post-industrial cities. Many brownfields have been regenerated for various uses, addressing a range of extant problems in urban areas. However, re-use plans for current brownfields are driven by market demand and public sector prioritization and do not always meet the requirements of local residents and visitors. In this paper, we investigate how a range of brownfields re-use options are perceived by residents and visitors to the Landek area in the city of Ostrava (Czech Republic). By analysing the results of the questionnaire survey (n=180) we found that future brownfields uses such as culture/sport and children´s park are the most popular options. We found that gender was a statistically significant predictor of preferred reuse options. Women are strong supporters of the above-mentioned re-use options, while men tend to favour re-use options which promote industry. Remarkably, respondents, in general, lacked concrete ideas concerning alternative re-use options of brownfields, suggesting that professional urban planners can be of assistance in the planning of the future use of brownfield sites.
Regeneration of brownfields gradually becomes an important challenge for regional and local development across the East-Central European countries. Due to the recent huge economic transition and global societal changes thousands of abandoned sites (brownfields) sprang up across the landscape after various economic activities, the Czech Republic included. This paper evaluates the perception of brownfields along with their individual re-use options by local population in one of the city districts of Ostrava which was heavily influenced by industrialisation during the last 150 years (Svinov city district, city of Ostrava, eastern part of the Czech Republic). The first part of the paper is devoted to theoretical aspects of brownfields regeneration and its perception. The second part of the paper presents us with the results of the questionnaire survey which was carried out among local population of Svinov (n=163) focusing on the perception of five selected local brownfield sites. It was found out that the issue of brownfields rouses huge discussions among public of the model area of Svinov. Among the most supported re-use options of local brownfields greenery and cultural facilities were identified. Brownfield sites located outside the settled area of the city quarter are almost disregarded while the re-use of centrally located sites for greenery is strongly supported.
As many other Western cities Budapest has been experiencing economic, political and social restructuring in the 1990s that has resulted in abandoned and underused areas – brownfields. “Transition zone,” “brown zone”, or sometimes also “rust zone” are just some of the various terms that have been used to describe the industrial areas in Budapest, located between city center and periphery (Kiss, 2007). These areas are a result of specific long, middle and shortterm processes, partly resembling restructuring of other European cities, partly other PostSocialist cities and partly influenced by Hungarian historical, political, social and economic context. Municipalities and developers are inclined to discuss and approach brownfields as plots of unused land, despite the fact that they are usually (under)used by transition economy. Redevelopment plans thus usually ignore the existing social, economic and political relations on these sites and envision only megalomaniac ideas for these in their understanding tabulae rasae.
Using an example of the Czech Republic, this explorative study attempts to answer the question of what factors have a significant influence on a successful regeneration of brownfields in a post-socialistic space. The study is based on a comparative analysis of two data files – the database of existing brownfields provided by the national CzechInvest agency, and the database of successfully regenerated brownfields compiled by the authors themselves. The paper consists of three interrelated parts, the first one dealing with an analysis of the structure of regenerated brownfields, the second one confronting this with the structure of the existing brownfields by means of a comparative analysis, and the third one analyzing the factors of brownfield regeneration. The main types of functional transformation of space were identified and the factors that appeared to be significant determinants of brownfields regeneration were classified as the result.

Uncovering Patterns of Location of Brownfields to Facilitate Their Regeneration: Some Remarks from the Czech Republic2018 •
The issue of brownfield regeneration is closely connected to balanced and sustainable development of regions, towns, and cities as it endeavors to reuse buildings and sites that have already lost their original use, but at the same time offers a possibility to generate new beneficial activities for the whole society that exceed just material or physical changes of the brownfield sites. The regeneration of every brownfield is usually a highly site-specific issue and individual and unique impacts of regeneration on the particular locality are obvious. Yet, several patterns in sets of non-regenerated brownfields can be identified. By finding and defining such patterns, a framework of indicators to facilitate brownfield regeneration can be created and the importance and strength of a particular indicator can be defined. By means of the analyses, we are able to recommend various relevant and most suitable approaches with regards to brownfield regeneration in individual regions. We have employed Factor Analysis (FA) for the identification of key factors of brownfield regeneration. In particular, Principal Component Analysis (PCA) was applied to conduct analyses of 1304 non-regenerated brownfields located in seven regions of the Czech Republic (NUTS 3 level). Data were obtained from publicly available brownfield databases of individual regional administrations. By means of Factor Analysis, it was ascertained that the most frequent factor that is typical for the surveyed non-regenerated brownfields is the ownership. The second most frequent factor is the size of the brownfields. As the third factor according to importance, the distance between the location of the individual brownfield and the municipality of extended powers (the so-called small district) was identified. By taking into account the results of the conducted analyses, brownfield regeneration policies of individual regions might be adapted to be more suitably targeted.
Compared to Western European or North American countries with developed market economies, the formation and acceptance of brownfields in post-socialist countries was delayed by approximately 30 years. For the Central European and partly Eastern European countries, the fall of the Iron Curtain and the transition after 1989 from a planned and state-controlled economy towards a market economy was unique for its time consistency. Yet, it was also specific for the distinct statuses of main sectors of national economy of individual countries, which got hugely manifested during the formation of spatial and functional connections concerning the problems of brownfields of all types (post-industrial, post-agricultural, post-military etc.). In the Czech Republic, there is a long history of industry; from the middle of the 19th century (the boom of the Industrial Revolution), it was regarded the most industrially developed country of Central and Eastern Europe. The massive deindustrialization of the 1990s caused increased concentrations of brownfield localities, with the local people and public administration becoming more familiar with them, and it also led to initial efforts for their systematic regeneration. The cities of Brno and Ostrava (Czech Republic), as well as other big cities in the Central European area, are typical examples for their finished intensive process of deindustrialization. Yet, regarding their economic preferences, and thus the existence of brownfields, they are highly distinct – in Brno there are more textile and engineering companies together with military and agricultural facilities; in Ostrava abandoned coal mining and metallurgical industry sites prevail. From the perspective of humangeographical methods and approaches, this contribution deals both with the functional-spatial consequences of brownfield existence in urban space, as well as with the results of research focused on the perception of the given issues by the residents of Brno and Ostrava. The research itself tries to demonstrate how the groups of selected respondents perceive and evaluate the brownfield problems from the perspective of their everyday experience.
