    Opis:
    The aim of the study was to diagnose the main trends of changes in land cover in selected communes of Polish metropolitan areas. Detailed studies were conducted in deliberately selected housing estates located in the core of metropolitan area (at least one housing estate) and communes located directly at the border of cities and located on the outskirts of metropolitan areas. The examined communes also differed in the quality of natural conditions of agricultural production. The study used LANDSAT 5 TM and RapidEye satellite images from three limited-time registrations (1996/1999, 2011, 2016/2017). On the basis of remote sensing data, changes in land use were specified by presenting them in a graphic form as compilation of numerical maps. The analyses were performed on processed images (colour compositions), which were subjected to supervised classification using the maximum-likelihood technique. The quality control of supervised classification showed accuracy of 89.3% for LANDSAT 5 TM scene analyses and 91.8% for RapidEye images. Kappa coefficient for the discussed classification was: 0.84 (LANDSAT TM) and 0.89 (Rapid Eye). The results obtained for individual metropolitan areas allow to identify the directions of changes (Land Use Change Cover) taking place in them, with consideration to specificity of each of them.

    Opis:
    The aim of the study was to diagnose the main trends of the changes in land cover around the urban agglomerations, as illustrated with the example of Lublin, over the last twenty years (1998–2016), as well as their statistical and graphical presentation in the form of digital maps compilation. The project was conducted on the basis of the remote sensing data: RapidEye and LANDSAT 5 TM satellite imagery from three temporal records (1998, 2009–11, 2016–17). Detailed research was carried out in purposefully selected municipalities. The performed analyses showed that in the studied municipalities some changes in the use of arable land and grassland occurred. The largest loss in terms of area share was recorded mainly in the arable land. At the core of the metropolitan area, i.e. in the city of Lublin, over the last 20 years the share of arable land in the total area decreased by almost 11 percentage points (p.p.). In the municipalities located directly at the border with Lublin, this loss was much lower, and was equal 4–5 p.p. Slightly larger changes occurred in municipalities located further from the core, where both in the category of very good and slightly weaker natural conditions, losses of arable land were greater than in municipalities located directly at the core’s border of the metropolitan area (MA).

    Opis:
    Land use conversion is a dynamic process that occurs all over the world. The scale of this process is global, and depends on related driving forces. There are numerous case studies of land use changes but only a few synthesise the results. The aim of the study is to analyse historical land use conversions in two villages located in peri-urban areas of the city of Kraków, and in particular, to indicate the directions of these changes associated with the distance of the given village to Kraków. The examples of two villages were selected so as to indicate the direction of changes in the immediate vicinity of the city as well as in a zone further outside the city. The aim is also to present a possible approach to monitoring the long-term development of these areas. As regards Poland, the expansion of urban pattern of land development outside the administrative boundaries of cities results in direct interference in agricultural production space, and not infrequently in areas having particular natural and cultural values. This is also the case within the zone of the direct impact of the city of Kraków on areas located to the south of the urban agglomeration. The article confirms that the changes involve the conversion of agricultural areas into built-up and urbanised areas. Nevertheless, the study results indicate an unexpected increase in the area of wasteland in close vicinity of the city, despite soil conditions being favourable to pursuing agricultural activities. It is a long-term study, which considers precise maps showing land use structure. It is the first step towards designing multi-scale studies that would consider land use changes in the neighbourhood of metropolitan areas.
