“…It would allow the creation of BGI masterplans, control urban environment quality in terms of sanitation, and build the ecosystem-based resilience of Polish cities to climate change and extreme weather events, significantly impacting towns in the Wielkopolska region [76,77]. Moreover, some applications could have a positive impact on reducing the outflow and decreasing environmental degradation [78].…”

In Polish law, no mechanisms exist to maximize the application and protection of blue and green infrastructure (BGI) in urban areas. A comprehensive legal framework does not entirely govern urban BGI facilities. Urban planning lacks an appropriate indicator, first and foremost. This study aimed to analyze the Polish legal criteria for the viability of designing and implementing BGI facilities. The authors also researched ways to aid legislators in growing and maintaining BGI in urban areas. In Poznań, a case study was carried out on applying the greenery planning and design law. Local spatial development plans (MPZP) are now the only legal tools in Poland that allow for the protection and establishment of BGI. According to data from Statistics Poland for 2021, the proportion of the country’s total area covered by existing local plans (based on current law) is around 20.51%. When the MPZP does not cover a portion of a municipality, administrative decisions are made by issuing development conditions (WZ) for the plot. WZ may become a tool for environmental damage under investment pressure. Ideas put forward by the authors are: (1) creating urban nature reserves (as one method of land use); (2) evaluating BGI as an integral part of eco-physiographic studies and spatial planning; and (3) creating a new urban indicator with more complex parameters.

Controlled Drainage Effectiveness in Reducing Nutrient Outflow in Light of Climate Changes

This modeling study focused on the hydrological and water quality effects of controlled drainage (CD) when operated using a subsurface drainage system in an agricultural field in the Wielkopolska region. The DRAINMOD hydrologic model was well calibrated and validated in an experimental field. This model was used in the performance of CD and free drainage (FD) combinations (108 and 27, respectively) in a near-future climate change scenario. The objective was to understand the potential of CD on the groundwater table (GWT), drainage outflow, surface runoff, and nitrogen and phosphorus reduction under projected climate conditions in Poland during the 21st century with shared socioeconomic pathway SSP370. The results indicated that the earliest start of CD practice is the most effective in increasing GWT. Compared to current climatic conditions, when applying CD on 1 March in the near future, with an initial GWT of 60 and 80 cm b.s.l. in wet years, drainage outflows will increase by 33% and 80% for the GFDL model, by 30% and 40% for the MPI model, and by 17% and 23% for the UKESM model. Comparing the surface runoff values obtained to current climate conditions, the MPI, GFDL, and UKESM models predict a significant increase in surface runoff in the near future, which is due to the predicted increase in precipitation. The annual NO3–N reduction was by 22, 19, and 15 kg per hectare for wet, normal, and dry years, respectively, in the near future. Among the climate scenarios, the UKESM model predicted higher NO3–N and PO4 leaching values compared to the MPI and GFDL models.
