What the literature leaves open

  • Directions The present study has certain limitations resulting from the characteristics of the adopted methodological approach. The analysis made it possible to identify *[email protected], *[email protected], *[email protected], *[email protected], *[email protected] 85 Gubański, J., Rubaszek, J., Podolska, A., Serafin, L., Niedźwiecka-Filipiak, I. (2026). The impact of large-scale logistics, commercial and industrial development on green infrastructure system: A case study of the Wrocław Functional Urban Area (Poland). Acta Sci. Pol. Administratio Locorum 25(1), 73–91. areas classified as industrial land in specific years within the boundaries of the planned GI system and its selected LaFUs; however, it did not provide detailed insight on how and to what extent the location of these areas contributes to the fragmentation of natural structures within the analyzed units. This limitation requires further research into land use/land cover patterns within individual GI units, with a particular focus on the spatial distribution of green areas forming the GI system, both in terms of their current state and temporal changes. In future stages of GI system monitoring, the scope of research should also be extended to include other types of development, particularly residential areas, as this form of land use is currently expanding in an uncontrolled manner under existing legal and spatial planning conditions (e.g. Kudłacz & Karwińska, 2021; Solecka et al., 2017).

  • Abstract Given the myriad of policy instruments aimed at enhancing water quantity conservation available to municipalities, what drives them to opt for a market‐based instrument (MBI)? MBIs can be effective and efficient policy instruments to enhance water quantity conservation, but there is little known about why municipalities utilize them.
