“…The recent scientific problem is finding a universal model for building cities' resilience to climate change. The assessment of urban development and the role of BGI are two of the most crucial research interests concerning mitigation and urban adaptation to climate change [68]. Some studies show that, to plan BGIs optimally and effectively, developing a data management system that connects administrative sectors and scientific disciplines in which citizens can participate is necessary [69].…”

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.

“…The referenced studies demonstrate that Geographic Information System (GIS) tools are crucial for identifying areas in need of further development to ensure sustainability and for effectively selecting components of blue-green infrastructure. Additionally, substantial research focuses on leveraging remote sensing data to analyze land cover change dynamics, especially in scenarios characterized by swift and significant urbanization [45][46][47]. Nevertheless, a unifying theme emerges from these studies-the automation of conducted analyses and the capacity to execute them over expansive geographical areas, objectives that this study also espouses.…”

The expansion of urban centers and peri-urban zones significantly impacts both the natural world and human well-being, leading to issues such as increased air pollution, the formation of urban heat islands, and challenges in water management. The concept of multifunctional greening serves as a cornerstone, emphasizing the interconnectedness of ecological, social, and health-related factors. This study aimed to identify potential locations for three specific types of blue-green infrastructure (BGI): bioswales, infiltration trenches, and green bus stops. Leveraging geospatial datasets, Geographic Information System (GIS) technology, and remote sensing methodologies, this study conducted a comprehensive analysis and modeling of spatial information. Initial cartographic representations were developed to identify specific locations within Olsztyn, a city in Poland, deemed appropriate for the implementation of the designated blue-green infrastructure (BGI) components. Following this, these models were combined with two additional models created by the researchers: a surface urban heat island (SUHI) model and a demographic model that outlined the age structure of the city’s population. This synergistic approach resulted in the development of a detailed map, which identified potential locations for the implementation of blue-green infrastructure. This was achieved by utilizing vector data acquired with a precision of 1 m. The high level of detail on the map allows for an extremely accurate representation of geographical features and infrastructure layouts, which are essential for precise planning and implementation. This infrastructure is identified as a key strategy for strengthening ecosystem resilience, improving urban livability, and promoting public health and well-being.

“…The promotion of green vegetation, and urban trees in particular, is considered as a main strategy to alleviate this issue [6][7][8][9]. Thereby, remote sensing is crucial to quantify the cooling effects of green infrastructure [10][11][12], and several studies evaluate the impact of trees on lowering urban heat island (UHI) effects in this field [13][14][15][16][17].…”

The cooling potential of tree species in Central European cities is insufficiently studied during extreme heat and drought, although a stronger surge in heatwaves compared to the global average is observed in this region. Remote sensing-based thermal surveys are an important tool to shed light on the mitigation effects of green infrastructure, but approaches covering extreme events are scarce. In this study, we present a simple, low-cost thermal airborne methodology that covers the current daily heat record in 2022, after the second warmest and third driest spring-to-summer period since 1949, in the medium-sized German city of Forchheim. We found that in spite of record-breaking heat and drought conditions, trees still had a considerable cooling potential with surface temperatures of 2 °C to 6 °C below air temperatures. Tree species were characterized by substantial median differences in tree surface temperatures up to 3.64 °C. Conifers and drought-sensitive broadleaf species showed the highest temperatures during the extreme event, while riparian species with potentially good water provision showed the highest cooling potential. In addition to tree species, imperviousness and tree NDVI were important variables for urban tree surface temperature, showing positive (imperviousness) and negative (NDVI) correlations with tree surface temperatures. Our study provides a methodological remote sensing example for the spontaneous and rapid coverage of extreme events, documenting the benefits of tree species in the urban context.
