Spatial absorbency assessment for sustainable land development
(Wydawnictwa AGH, 2020) Broża, Noemi; Birnbaum, Karolina; García Castro, David; Kazak, Jan
Sustainable land use development requires a smart decision‑making process based on appropriate spatial design patterns. However, the pro‑investment policy of many municipalities often results in disproportions between the demand and supply of investment areas, which means that spatial development is not realized in a sustainable way. In order to avoid the overconsumption of land for investment purposes, central government in Poland introduced a requirement to assess land balance, which includes the calculation of spatial absorbency at the level of local urban planning. The aim of this work is to develop the concept of spatial absorbency assessment. In order to select best practices, document reviews of local spatial policies in Kalisz, Łódź, Toruń and Gdańsk were performed. Based on the review, a method for spatial absorbency assessment was presented. The applicability of the proposed solution is presented by its use on the case of the Racibórz municipality. The visualization shows what kind of geoinformation is required to perform an assessment by means of the developed method. The results of the calculations present the final feedback that is received by local authorities. The work was carried out using ArcGIS software. The obtained results may constitute the basis for further multi‑dimensional analyses as part of sustainable land development planning at the local level.

The effectiveness of master plans - case studies of biologically active areas in suburban zones
(Wydawnictwa AGH, 2022) Błasik, Magdalena; Wang, Tong; Kazak, Jan
Sustainable development on a local scale requires well-functioning instruments in the spatial planning system. Any weakness in the planning system may result in forms of spatial development that are socially, environmentally or economically disadvantageous. Therefore, the aim of this study was to examine whether master plans and land development monitoring in the Polish system are effective instruments in shaping sustainable spatial development. The factor analyzed was the share of a biologically active area and four villages located near a regional city were analyzed. Data from master plans, cadaster and orthophoto maps were used in this study. Verification of land use made it possible to evaluate whether the properties meet the provisions of spatial planning documents. In each of the analyzed villages, properties that do not meet the provisions of master plans were identified. In one of the villages, more than half of the properties had a smaller share of biologically active areas than permitted by the local law. The research also analyzed alternative scenarios of the potential impact of the application of permanent vegetation on sealed surfaces. These results showed that using green roofs, for example, can significantly reduce the problem of local laws being broken. The results quantitatively confirm that the provision of master plans in the Polish system are not effective tools in regulating land development.

Towards transit-oriented development for sustainable urban mobility - insights from a central european city
(Wydawnictwa AGH, 2021) Leśniewski, Maksymilian; Świąder, Małgorzata; Kaczmarek, Iwona; García Castro, David; Kamińska, Joanna; Pilawka, Tomasz; Kazak, Jan
Sustainable Development Goals require holistic actions, including activity at the intersection of urban planning and environmental engineering. Turning our cities towards transit oriented development might help in reducing pollutant emissions caused by individual transportation modes that rely on crude oil. This research presents how the use of geospatial network analysis can support local decision makers in the evaluation of potential public transport accessibility by citizens in the case of a Central European city - Wrocław (Poland). The obtained results indicate differentiation in access to railway stations and stops, which results from pedestrian path networks and the number of entrances to railway stations. The visualization of serve area shows which parts of the city are excluded from comfortable access to public transport and in that way high light where future actions should be taken.
