Large shopping centres in Poznań as a source of rainwater recovery and irrigation of urban green areas

Large-scale facilities in the city cause the loss of significant amounts of rainwater,
greenery and biologically active areas. Remedying this situation requires the implementation
of a number of spatial planning demands. Increasing the attractiveness and spatial value of
urbanised areas state fundamental importance for meeting the needs of local communities
in the era of predicted climate change. The study shows that appropriate management of
water recovered from the roofs of large-scale buildings can be used to supply significant
areas of urban greenery.
