Approaches to Post-Mining Land Reclamation in Polish Open-Cast Lignite Mining

Abstract

The paper presents the situation regarding the reclamation of post-mining land in the case of particular lignite mines in Poland until 2012 against the background of the whole opencast mining. It discusses the process of land purchase for mining operations and its sales after reclamation. It presents the achievements of mines in the reclamation and regeneration of post-mining land as a result of which-after development processes carried out according to European standards-it now serves the inhabitants as a recreational area that increases the attractiveness of the regions.

Algorithm Of Revitalization Programme Design For Housing Estates

Abstract

Demographic problems, obsolescence of existing buildings, unstable economy, as well as misunderstanding of the mechanism that turn city quarters into areas in need for intervention result in the implementation of improvement measures that prove inadequate. The paper puts forward an algorithm of revitalization program for housing developments and presents its implementation. It also showed the effects of periodically run (10 years) three-way diagnostic tests in correlation with the concept of settlement management.

Green Construction in Building Renovation

Abstract

Modern materials and construction solutions draw more and more attention to ecology and building certification. Among the criteria appearing in revitalization, an important element is bringing plants back into heavily urbanized areas. In its natural form, this is not possible to carry out everywhere, often requiring large amounts of space. Nowadays, however, there are a number of green roofs and green wall systems, allowing “greener” construction without making significant changes in the urban environment.

The article includes a presentation and analysis of selected solutions of biological surfaces known as green roofs and green walls, specifying various solutions and their most important features. The case study focuses primarily on material and design solutions, as well as the potential benefits, risks and limitations in their use.

Plants structures on the surfaces of vertical and horizontal partitions continue to be a very interesting alternative to take into account when applying for grants, such as LEED or BREEAM certificates.

Ecological and Social Aspects in the Managementof Post-Mining Areas.an Example of the Adamów Lignite Basin

Abstract

The study presents a management model for post-mining areas, which includes the process of reclamation and management in the context of the socio-ecological system. This means that it is necessary to include the relations in the management system that occur between the main stakeholders (internal relations) and the ecological, economic and socio-cultural conditions of the environment (external relations). Verification of the recommended model was carried out on the basis of the analysis of environmental, economic and socio-cultural processes currently observed in the Adamów Brown Coal Basin, which is in the phase of liquidation. The conclusion presents constraints in the legal system that are not propitious for comprehensive solutions in the field of revitalization.

Renovation of Large-Panel Buildings in Context of Urban Renewal/ Remonty Budynków Wielkopłytowych, Jako Element Rewitalizacji Miast

Abstract

The article presents issues connected with renovating multi-storey precast concrete buildings, resulting from the consequences of construction defects occurring over the course of the building process and use of the buildings, as well as design flaws and construction defects when insulating external partitions. Analyses and conclusions which stem from them cover issues of renovation in the light of: damage in the vertical and horizontal joints, damage to the connection of layers in three-layer load-bearing and curtain walls, the effect of the damage on the possibilities of carrying out functional modernization of residential units, the effect of the damage on the effectiveness of thermo-modernization - new problems related to faulty insulation

Study Possibilities of Present-Day Ethnic Revitalization of German Woodsmen in the Little Carpathians

ABSTRACT

The article discusses the influence of macro-social processes and issues of assimilation, acculturation, ethnic and linguistic revitalization on the example of one particular group of German woodsmen in the social context of Western Slovakia. It attempts to analyse how historical and political changes during the 20th century influenced changes in the structure, system of values and hierarchy of ethnic group and whether that helped or prevented the assimilation of the group’s members. The article also attempts to indicate the possibilities of today’s ethnic and linguistic revitalization.

Sustainable revitalization of brownfield lands – possibilities of interim utilization in the form of urban community gardens

Abstract

Our PhD researches include brownfield revitalization,1 the application of the methods of interim utilizations on greeneries,2 and the formation background and potential of community gardens.3 We compared our systems of criteria in hope of extensive research conclusions. In order to trace the urban development possibilities in Budapest, we analysed brownfield revitalizations where the interim utilizations included allotment gardens, too. We concluded that such developments are likely to create environmental and social added value. Early results of the valorization process are important by themselves, but the perpetuation of interim land utilization holds even greater values.

The effect of the conditions of a landscape on its retention capacity

The effect of the conditions of a landscape on its retention capacity

Questions related to the occurrence, frequency, intensity, duration, characteristics and causes of floods have been discussed more in recent years. Two basic approaches to flood control often conflict. The first is based on the assumption of the considerable effect of a landscape's retention capacity, which can in fact prevent surface runoff generation and flood formation and can significantly transform flood wave. The second approach asserts that the retention capacity of a landscape is nearly negligible and that the only reliable flood protection can be provided by extending the technical structures of flood control measures mainly and directly on water courses. Two different approaches were applied to assess the effect of landscape conditions and revitalization measures on surface runoff and flood formation within a catchment and floodplain. The conclusion shows that the effect of landscape revitalization is very important, but mainly for low return periods of flood events, while for extreme events, the effect on landscapes and floodplains becomes less important and even negligible.

The Activities of Local Governments in the Revitalization of Public Space in Bulgaria and Poland

Abstract

The research discussed in the article focuses on public space in urban areas and revitalization activities carried out by local governments. The goals of the paper are to identify the conditions and opportunities for the development of public space by local governments of Bulgaria and Poland, to find regularities (similarities and differences) and to assess the actions taken. The specific objective is to illustrate the process of planning and managing selected large revitalization investments in urban public spaces in Bulgaria and Poland. The research methods used comprise the analysis of literature, including official documents and acts of law and case studies.

The paper analyzes the conditions and manifestations of activities taken by local governments regarding investment in public space (development and revitalization of public space programs and investing in real estate) in Bulgaria and Poland, using examples from selected cities. The authors selected two comparable urban areas: Varna in Bulgaria and Poznań in Poland, chosen intentionally due to the similarity of the two post-socialist bloc countries and the availability of information. Bulgarian and Polish state law and various acts of local law were analyzed. The experimental part of the publication introduces case studies of investments in the revitalization of real estate in public space managed by the local governments. It shows examples of projects which are relevant to the development of the cities under study.

Possibility of utilization directing structures in river revitalization

Possibility of utilization directing structures in river revitalization

Directing and concentrating structures are mainly used on water courses with unstable channels and major sediment transport or in areas with major bank erosion. The main purpose of these structures is to redirect water flow from the stressed and very often eroded bank to the centre of the channel or other parts of the channel, where the water flow may be used, e.g., for dispersion of unsuitable deposits before its eventual stabilization by natural succession. Another important goal is to achieve a desired change in a stream channel by using the transporting power of the water flow and targeted deposition of any sediment. The area of a deflecting structure, a so-called hydraulic shadow, also appears where sediment is deposited (deflector). The objective is to achieve the deposition of sediments at desired places in the stream. It is possible to design a whole range of suitable or less suitable types of flow deflectors. In our article, we will particularly focus on problems of revitalizing a water course; i.e., the design of structures from biological or biotechnical elements for channel stabilization.
