The aim of the article is to present the process of changes which occurred from the 1970s until 2012 in the areas of urban agglomerations in Poland. In contemporary agglomerations in Poland, their socio-economic function is centralized while land use and building development become progressively decentralized, which results in dynamic growth of the central metropolitan area, and in simultaneous deurbanization of its zone of influence. The described problem is typical of the Warsaw Urban Agglomeration (Warszawski Zespół Miejski, WZM), where the population of the metropolitan zone increases while the importance of the surrounding towns, particularly in their central areas, decreases. The objective of this paper is to present these contemporary trends in the communes of the northern zone of WZM. The analysis involves three towns: Legionowo, Nowy Dwór Mazowiecki, and Zakroczym, and two communes – Jabłonna and Wieliszew. The results are compared with relevant changes occurring in the communes of the Piaseczno district. The examined processes are also confronted with the proposals and arrangements included in planning concepts prepared in different periods for the agglomeration. The escalating suburbanization, characterized by deurbanization visible in spatial planning, affects the effectiveness of newly created building developments and their rank of service centres, and also shows the failure of long-term planning, which is not supported by detailed analysis and research.
This paper is a comparative study of main social theories of urban development in the last fifty tears. The author presents various approaches and social theories from across the world. He divides the after-war period into three phases according to the profound social changes. the first one covers the years of ending the post-war reconstruction of economy, infrastructure and cities damaged by the war. the second phase includes "the golden years" between approximately 1955 and 1975, when the formation of different types of welfare state, but mainly the urban population growth, suburbanization and metropolization processes and improvement of living conditions and urbanities took place. the third phase, covering the years between 1975 and 2000, is marked by the first signs of the decline of the welfare state accompanied by deepening social inequalities increasing urban poverty, marginalization of some groups of the population, political radicalization and urban conflicts as well as by urban and regional polarization.
In recent years, the largest Polish cities have experienced intensive suburbanization processes. People migrate to suburban communes and hitherto undeveloped areas change their function towards single- or multi-family residential neighbourhoods. Spontaneous and dispersed suburbanization processes (urban sprawl) have many negative consequences that might become a serious problem, not only for the inhabitants but also for the local authorities in the suburban areas. The article presents the results of the evaluation of the role of Cohesion Policy projects in counteracting negative effects of suburbanization processes in potential suburban zones of the largest Polish cities. The results of the evaluation indicate that in suburban areas there is a major focus on meeting the current needs of residents, whereas strategic prevention of negative effects of suburbanization processes is neglected.
Sustaining the development at the local level is associated with many different issues. One of the major ones is the urban growth policy. This can be justified by the importance of space as one of the most important environmental assets, which has to be treated as non-renewable one. At the same time it is necessary to remember that the shape of this policy is influenced by many factors, i.e. legal regulations and current paradigm of urban development. Along with introduction of the sustainable development concept this paradigm evolves. Currently as some of its most important components one should mention urban regeneration of the degraded areas and limiting urban growth to the areas already urbanized. As far as urban regeneration is discussed, it is possible to mention a number of issues that have to be taken into account. At the same time one can regard the inside growth of cities which means reusing degraded areas – as real alternative to the on-going suburbanization and encroachment of urban structures to the areas still remaining its agricultural or natural character.
The paper includes the most important results of the project of the same title, carried out as part of a larger project “The Development Trends of the Mazovia Region”, implemented for the local government of the Mazowieckie voivodship in 2010?2012. It primarily concerned demographic and settlement issues related to the evolution of functional relations and linkages, spatial availability, as well as infrastructure and land use conditions. The main objective was to formulate the conditions which would ensure development, and to identify the factors and conditions that affected easy flow of development stimuli and better efficiency of the suburban zone and spatial cohesion of the Mazovia region. The horizon time of the project concerned the period after 1990 (diagnosis and retrospective study) and 2030 (forecast). The paper has a survey character, it reports on selected topics only, and its aim is to disseminate important research results.
