An Analysis of Urbanisation Dynamics with the Use of the Fuzzy Set Theory—A Case Study of the City of Olsztyn

Abstract

Quantitative, qualitative and structural changes in land use that occur in a given location over time are a manifestation and a measure of urban development. Urbanisation is a process of spatial diffusion that spreads from the urban core to peripheral areas. Urban development is linked with human activities in a specific location and in a given period of time. In the context of spatial management, urbanisation is a process where less intensive land-use types are replaced by more intensive forms of land use. The demand for new land for residential development, the search for alternative locations for housing construction and the development of sustainable land management plans require new methods that support decision-making in the process of land conversion in peri-urban areas. The aim of this study was to develop a methodology for identifying and localising the boundaries of urban development with the use of the fuzzy set theory and to analyse the rate of changes in land use based on data for 2005–2010–2017. The proposed method supports the identification and localisation of urbanised areas and an evaluation of the degree of urbanisation in the interval [0,1]. The case study was conducted in the Polish city of Olsztyn.

An evaluation of urbanisation processes in suburban zones using land-cover data and fuzzy set theory

“…The questionnaire consisted of a comparison matrix in which respondents identified the intensity of anthropogenic elements on a particular site, described by a specific land use ("←", "O", or "↑" for which the values were 2-1-0, respectively). The totals of values derived from all surveys were averaged and then used to calculate a value denoting the proportion of urban land-use types (wp) (Biłozor et al, 2020).…”

“…Fuzzy sets have been used to analyse the ruralurban continuum by identifying and defining landuse types in the rural-urban fringe (usually a large city) (Biłozor et al, 2020). In this method, the degree of membership of land-use types in a set of urban functions was evaluated, and the spatial range of urban land-use types was determined (Biłozor et al, 2019).…”

Hybridization of valuation procedures as a medicine supporting the real estate market and sustainable land use development during the covid-19 pandemic and afterwards

“…This phenomenon is also visible in the area of property valuation methodology. It seems that as never before the valuation procedures has chance to be extended by the alternative solutions based on the modern technology ( Biłozor et al, 2020 ; d’Amato and Renigier-Bilozor, 2017 ; Renigier-Biłozor et al, 2019b ; Helling, 2019 ; Osorno-Covarrubias et al, 2015 ). Standard activities of property valuers performed at stages of the valuation procedure may (and during a pandemic should be) replaced or supplemented by modern technologies as part of the hybrid approach.…”

An Analysis of an Area’s Vulnerability to the Emergence of Land-Use Conflicts

“…The specificity of land-use conflict has to be explored to expand our understanding of the scope and potential consequences of such conflicts, which could play a key role in rational and sustainable management of space [46][47][48].…”
