The role of rivers in creating a blue-green city economy on the example of Wroclaw and Gdansk

The article aims to analyse and critically evaluate the use of blue-green infrastructure in the city. The study was conducted on the example of the Wrocław and Gdańsk rivers. An essential element of the analysis is to determine the possibilities of introducing and improving blue-green infrastructure by using good practices in these urban units, particularly those relating to the role of rivers. During the study, the following research questions were formulated: What megatrend of urban development is defined by current conditions, and what do urban units gain in this way? Is the blue-green potential of the examined cities effectively used? What is the state of development of blue-green zones in and around the river? The methods used to write the article are desk research, case study, analysis of the researched areas using up-to-date cartographic materials, IDI, literature, and legal status analysis. The study supports the exchange of information between cities and the management of the river in the city.
