Shore zones are transition areas (ecotones) between aquatic and terrestrial ecosystems. Their function in the environment is crucial because they serve as buffer zones that capture pollutants and slow down erosion of reservoir and watercourse banks provided that they are managed properly. Research on a shore zone was conducted at the Mściwojów retention reservoir with an innovative water self-purification system. After several years of its operation, an increased phosphate concentration in the main part of the reservoir was reported. The mapping of the terrain's surface and modeling of hydrological processes in the direct catchment area of the said reservoir were done using the digital elevation model (DEM). The DEM was created from LiDAR data obtained in 2012 by airborne laser scanning. Analyses of the surface runoff led to identification of surface runoff transport pathways, along which the eroded material from cultivated fields is discharged directly to the reservoir. Surface runoff transport pathways gather the eroded material from a maximum area of 45,000 m(2) in the western part of the direct catchment and 40,000 m(2) in the eastern part of it. Due to the reservoir management negligence, the riparian zone designed for the Mściwojów Reservoir no longer exists. The percentage of the natural shore that undergoes erosion processes is over 54. The said processes and fluctuations of the water level in the reservoir, as well as degradation of the shore zone caused by human activity, bring about limited plant development in the littoral zone, which in turn lowers the reservoir's resistance to degradation.

The understanding of price-setting attributes operating on local real estate market is not only an essential element of property appraisers’ work, it can also greatly assist the professional activities of real estate agents. However, its primary importance is for the market – facilitating the decision-making processes of developers (developers become aware of the buyers’ expectations and preferences, making it possible to more accurately form market offers and pricing strategy). With the use of computer-assisted interviewing, a questionnaire was designed to find out students’ preferences in the housing market of large Polish cities. The research was undertaken at six universities: Nicolaus Copernicus University in Torun, Poznan University of Economics, Wroclaw Medical University, Wroclaw University of Environmental and Life Sciences, University of Technology and Life Sciences in Bydgoszcz, and President Stanislaw Wojciechowski Higher Vocational State School in Kalisz. At each university, the survey was carried out on two groups of students: one included those who had chosen specializations related to the real estate market, the other one – students who did not explore the subject of the real estate market in their field of studies. The research can make a significant contribution to the problems of real estate market analysis. The results are the first part of a broader concept of research, which ultimately aims to internationalize the findings.
