“…Gambar 2 Ilustrasi perbedaan suhu pada area bervegetasi dan tanpa vegetasi tanaman [12] Sedangkan pemilihan area tepi dan median jalan untuk ditanami vegetasi tipe pohon yakni karena pembentukkan pulau panas perkotaan sering terjadi pada area ini. Diketahui adanya material-material baru di permukaan perkotaan seperti beton, aspal, ubin, dan material lainnya kemudian bergabung dengan emisi panas, kelembaban, serta polutan secara dramatis merubah suhu permukaan di atas atmosfer menjadi lebih panas [5] dan membentuk karakteristik iklim mikro yang khas dengan terbentuknya pulau panas, akibatnya albedo material bangunan yang rendah menyebabkan tingginya penyerapan panas di daerah perkotaan [4] .…”

Pembentukan pulau panas atau dikenal dengan istilah urban heat island (UHI) merupakan fenomena iklim mikro di suatu wilayah perkotaan yang formasinya dipengaruhi oleh kepadatan penduduk, geometri perkotaan, penggunaan lahan dan tutupan lahan. Potensi UHI di wilayah perkotaan sangat signifikan tak terkecuali di Kota Kendari yang pertumbuhan penduduk, serta aktifitas pembangunan di wilayahnya meningkat pesat tiap tahunnya. Pemahaman masyarakat tentang fenomena tersebut pun masih kurang dan juga belum menyadari pentingnya mitigasi kebencanaan akibat perubahan iklim. Program kemitraan masyarakat (PKM) yang dikemas dalam bentuk pengabdian ini bertujuan meningkatkan pengetahuan dan pemahaman masyarakat dalam strategi mereduksi UHI. Pencapaian tujuan dilakukan dengan metode pembelajaran kepada masyarakat melalui ceramah/diskusi secara langsung, serta kegiatan aksi penanaman vegetasi tipe pohon pada wilayah yang memiliki indeks vegetasi < 0.5. Hasil PKM menunjukkan meningkatnya antusiasme mitra sasaran dalam kegiatan pembelajaran strategi mereduksi UHI melalui rekaya vegetasi tanaman dari tipe pohon, semak, dan rumput, dan melalui rekayasa pewarnaan bangunan seperti penggunaan warna cat yang kurang menyerap panas serta pembelajaan tentang konsep vertical garden. Sedangkan dalam kegiatan aksi penanaman vegetasi tipe pohon, tim dan mitra berhasil menanam sebanyak 30 bibit pohon trembesi di tepi dan median jalan. Pohon-pohon tersebut nantinya akan menjadi sumber vegetasi yang mampu mengurangi efek UHI.

“…Urban greenery plays an essential role in shaping local climate. It plays the role of urban air conditioning that cools down the environment and balances temperature through evapotranspiration [1]. Green infrastructure (GI) is defined as areas that maintain natural ecological processes, support air resources, and foster health and quality of life [2].…”

The aim of the research was to valorise the analysed urbanized area in the direction of determining the hierarchy in the order of interventions aimed at increasing the share of biologically active area and natural field retention, the potential impact of green roofs on the valorisation of the studied urbanized areas. The research covered the Gajowice estate in Wrocław. The scope of the research included the division of the area into working cells, for which valorisation was carried out using the point method based on the criterion of the degree of covering the land with vegetation and the degree of covering the area with various types of buildings. The valorisation result was determined on the basis of a comparative matrix taking into account the results of the partial assessment of vegetation and building cover. The impact of green infrastructure (green roofs) on valorisation was simulated by proposing their location on buildings with the so-called big plate. The introduction of green roofs on selected buildings improved the valorisation result in some research cells, reducing the number of cells requiring intervention. This raised the valorisation assessment by even two classes, which resulted in a significant reduction in the number of critical areas, with too much hardened surface, and increased the number of areas with a satisfactory level of biologically active surfaces.

“…These areas should be marked out and should create an organic network of mutual relations, penetrating built-up areas (Sandström 2002). It is this local network of connections that has the greatest impact on the quality of inhabitation in the city, climate improvement (Chen, Jim 2008, Liu, Li 2012, Hesslerová et al 2022, natural biodiversity (Kattwinkel et al 2012) and spatial structure of the city (Kotus 2006).…”

The greenery and water structure, in the form of wedges cutting into the city, is a characteristic and unique element of Poznań’s urban model. Already before the Second World War, it became the matrix setting the framework for spatial and natural connections within and around the city. These areas were originally clearly demarcated and formed an organic network that permeated the built-up areas. It was this local network of linkages that was to have the greatest impact on the quality of urban living, climate improvement, biodiversity and the functional and spatial structure of the city. In the idea of the socialist city, ensuring access to green spaces for the masses, was one of the essential policy elements of the time. However, over time, in the various models of the city proposed by successive planners, these interconnections began to disappear and the individual bands were narrowed and sometimes discontinued altogether. This study aims to verify the urban planning models of the city of Poznań against the original idea of a wedge-ring system of greenery and water areas, before and after the political transformation in 1989. How does this original structure function today and how have the socio-economic changes that followed the fall of communism affect the greenery and water solutions proposed in the new city model? A comparative analysis of changes in green and water structure in the different spatial models of the city of Poznań, before and after the political transformation, makes it possible to observe the pace and directions of these changes. The analysis was based on the findings of the then-current master plans and on the studies of spatial development conditions and directions, which are an expression of the city’s spatial policy. It can be used to verify the assumptions made or even to change the current model of the city.
