AbstractGreen areas located on the peripheries of cities have the potential to become green public spaces not only of recreational but also educational character, promoting at the same time the knowledge about environmental protection. The cities included in the research belong to the małopolskie voivodeship (Lesser Poland voivodeship). With the use of geospatial data of land cover, as well as territorial forms of environmental protection, it was pointed that 48.4% of forest, wooded and shrub green areas located within city borders are covered by a form of environmental protection, thus being a valuable resource of significant nature potential. Making such spaces available in a conscious and attractive way is presented on the example of projects implemented in the cities of: Stary Sącz, Nowy Targ and Kraków. The presented projects were used to make recommendations for city authorities to create green public spaces.

Lichen Flora

Die Flechtendiversität und -quantität wurde in den Jahren 2017/2018 in Rostock an 53 Bäumen erfasst. Die Ergebnisse wurden mit den Ergebnissen einer Kartierung von 1994/1995 verglichen. Ferner wurden die Feuchtigkeitsverhältnisse und der Grad der Eutrophierung bzw. die Luftqualität an den Bäumen der Gattungen Tilia und Acer anhand des bekannten Verhaltens der nachgewiesenen Flechten bezüglich Luftfeuchtigkeit/Niederschlägen, Eutrophierung und pH-Verhältnissen bewertet. 2017/2018 wurden 79 Flechtenarten und 14 lichenicole Pilzarten nachgewiesen. Die Gesamtzahl der im Untersuchungsgebiet nachgewiesenen epiphytischen Flechtenarten erhöhte sich damit auf 80. Die meisten Flechtenarten kommen an Tilia spec. (60), Acer pseudoplatanus (43) und A. platanoides (34) vor. Die häufigsten Arten sind Phaeophyscia orbicularis, Physcia adscendens, Ph. tenella und Xanthoria parietina. Candelariella xanthostigmoides, Flavoparmelia soredians, Hyperphyscia adglutinata, Intralichen lichenum, Lecanora subcarpinea, Parmelia serrana, Parmelina quercina und Taeniolella delicata sind Neufunde für Mecklenburg-Vorpommern. Hinsichtlich der Verbreitung und des Charakters der Fundorte können die nachgewiesenen Flechten und lichenicolen Pilze drei Gruppen zugeordnet werden: 1. Arten, die auch an stark befahrenen Straßen oder in eng bebauten Wohngebieten mit wenig Grünflächen und in den Stadtgebieten Kröpeliner Tor-Vorstadt oder Stadtmitte vorkamen, 2. Arten, die auch noch in locker bebauten, grünreichen Wohngebieten und in kleineren Grünlagen der Neubaugebiete vorkamen, aber nicht mehr in der Kröpeliner Tor-Vorstadt und Stadtmitte nachgewiesen wurden, 3. Arten, die nur an Bäumen vorkamen, die sich in der Nähe zum Offenland befinden. Der ersten Gruppe wurden 22, der zweiten Gruppe 32 und der dritten Gruppe 25 Flechtenarten zugeordnet. Dem Verhältnis zwischen der Frequenzsumme der stark nitrophytischen Arten und der Frequenzsumme der a-, schwach und mäßig nitrophytischen Arten auf den Bäumen entsprechend, wird die Luftqualität an 15 Bäumen der Gattungen Acer und Tilia für gut, an 14 Bäumen für mäßig und an 13 Bäumen für schlecht befunden. Auf der Grundlage des Verhältnisses zwischen der Anzahl basiphytischer Arten und der Summe an Arten an sauren oder/und subneutralen Borken wurden sechs Standorte als wenig, 21 Standorte als mäßig und 15 Standorte als stark schadstoffbelastet eingestuft. Meso- bis hygrophytische Flechten kamen an zehn Standorten mit nur ein oder zwei Arten, an 21 Standorten mit drei bis fünf Arten und an elf Standorten mit mehr als fünf Arten vor. Die epiphytische Flechtenflora hat sich in Rostock seit 1995 gravierend verändert. Es nahmen 69 Flechten im Bestand zu, von denen sich 52 Arten erst nach 1995 angesiedelt haben. Bei 32 Flechten ist eine schwache, bei 19 Flechten eine mäßige und bei 18 Flechten eine starke Zunahme zu verzeichnen. Lecanora conizaeoides kam 2017/2018 nicht mehr vor, vier Arten haben im Bestand abgenommen. Changes in the epiphytic lichen flora in the urban area of Rostock between 1994/1995 and 2017/2018 In 2017/2018, diversity and quantity of lichens were studied on 53 trees in Rostock city. The results were compared with the results of a mapping project in 1994/1995. Humidity conditions and degree of eutrophication at trees of the genera Tilia and Acer were interpreted with reference to the known indicator characteristcs of the lichen species concerning air humidity/precipitation, eutrophication and pH conditions. In 2017/2018, 79 lichen species and 14 lichenicolous fungus species were found. The total number of lichens increased to 80 species. Most species were found on Tilia spec. (60), Acer pseudoplatanus (43) and A. platanoides (34). The most common species are Phaeophyscia orbicularis, Physcia adscendens, Ph. tenella and Xanthoria parietina. Candelariella xanthostigmoides, Flavoparmelia soredians, Hyperphyscia adglutinata, Intralichen lichenum, Lecanora subcarpinea, Parmelia serrana, Parmelina quercina and Taeniolella delicata are new to Mecklenburg-Western Pomerania. The distribution and characteristics of the collection sites allow for deviding the species into three groups: 1. species also present along streets with heavy traffic or in densely populated residential areas with a lack of green areas and in the districts Kröpeliner Tor-Vorstadt or City Centre, 2. species still present in sparse residential areas and smaller green areas but not in the districts Kröpeliner Tor-Vorstadt or City Centre, 3. species only colonizing trees close to the open landscape. Twenty-two species were assigned to the first, 32 species to the second and 25 species to the latter group. According to the proportion between the sum of frequencies of the strongly nitrophytic lichens and the sum of frequencies of the anitrophytic and moderately nitrophytic lichens on trees, air quality was indicated to be good at 15 trees of the genera Acer and Tilia, moderate at 14 trees and bad at 13 trees. Based on the proportion between the number of basiphytic lichen species and the sum of species colonizing acidophytic and subneutrophytic bark, six locations were categorized as little, 21 locations as moderately and 15 locations as strongly polluted. Mesophytic or hygrophytic lichens were present with only one or two species at ten locations, three to five species at 21 locations and over five species at 11 locations. Within the period under consideration, the epiphytic lichen flora of the Rostock urban area changed considerably. The populations of 69 lichen species increased, with 52 lichens newly establishing after 1995. In 32 lichen species a slight, in 19 species a moderate, and in 18 species a strong population increase was recorded. Lecanora conizaeoides disappeared and the populations of four species decreased.

Green Areas

Urban green areas present a lucid example for the harmonious co-existence of the artificial and natural environments best illustrated by their interdependence and interconnection in urban spaces. Urban green areas are essential for the health and wellbeing of citizens. The present study aimed to investigate those multiple benefits for citizens that arise through the existence of urban green areas, as well as important policy dimensions that should be considered when designing the expansion of urban green spaces in urban development. The study was based on a literature review to examine for available evidence on the benefit levels derived by the existence of urban green areas. An extended literature review was followed by a structured review, based on specific inclusion and exclusion criteria, which partly followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The search was conducted in two databases, and a total of 1674 articles and abstracts were identified through the database searches. After removing 114 duplicates, 1560 records were initially screened based on title and abstract. Following inclusion and exclusion criteria, 14 articles were incorporated in the structured review and a total of 47 in the extended review. The extended literature review identified 33 additional articles examining aspects of benefits that did not fall under the pre-established inclusion and exclusion criteria used in the structured review, such as health benefits and other social parameters associated with urban green spaces. The selected studies were allocated in five principal groups according to study types: three of the them consisted of studies employing “willingness to pay” (WTP) methods, five were based on property values, two studies assigned monetary values, while another two assigned CO2 values, and, finally, two studies were based on qualitative criteria. The results indicated benefits to citizens and increased welfare levels gained by the existence of urban green areas. The conducted review revealed a number of findings and recommendations that could direct future research and urban policy. Those hints could assist local authorities as well as stakeholders in order to measure and assess the benefits of green spaces and urban parks and promote measures and programs to assist their further deployment.

Health And Well Being

The quality of life in our cities critically depends on the intelligent planning and shaping of urban living space, in particular urban nature. By providing a wide range of ecosystem services (ES), urban nature essentially contributes to the well-being of city dwellers and plays a major role in avoiding common diseases through its positive impact on physical and mental health. Health is one of the most important factors underlying human welfare and is, thus, vital to sustainable development. The ES of urban green space provide other social-cultural functions alongside public health, for example by fostering environmental justice and citizenship participation. Thus, they should always be considered when searching for solutions to urban problems. The aim of this research was to determine the impact of green areas in three selected cities on the health and well-being of people by self-reporting of green areas’ visitors. To this end, we posed the research question: which types and characteristics of urban green space are most appreciated by city dwellers? Based on our findings, we have drawn up recommendations for practices to promote better living conditions. We have also pinpointed obstacles to and opportunities for leisure time activities as well as ways of supporting the public health of citizens.

Health And Well Being

Natural environments have been shown to promote health, and are, therefore, important for achieving social sustainability in cities. As cities grow and become denser, it is important to develop knowledge about the characteristics of natural environments that work to promote health. Perceived Sensory Dimensions (PSDs) is a tool that defines eight different cultural ecosystem services. They correspond to different human needs (rest, exercise, socialising, pleasure, or security) resulting in rehabilitation and health and well-being promotion. An experiment was conducted to study the potential of PSDs to restore people who experienced stressful accidents. One hundred and fifty-seven participants were recruited and asked first to watch a film clip of serious accidents, then to look at the pictures, depicting one particular type of PSDs, while listening to its respective audio recording. Their stress levels were measured before exposure to the stressor (baseline), after exposure to the stressor (pre-test), and after exposure to a particular type of PSDs (post-test). The results show that all eight PSDs effectively provide mental recovery, but there are statistical differences in their potentials. As such, it is proposed that the combined potential of the PSDs is needed, and should be used to increase the capacity and supply of health-promoting urban green areas.

Issues related to the system of protection and planning of rural landscape undoubtedly differ from the topics concerning the transformation of agricultural areas and their proper management. These are separate specialties, studied by researchers representing different disciplines, although they often relate to the same village and they are aimed to implement the ideas of the Green Deal and sustainability. The experience from independent research projects in Kamionka Wielka (agricultural areas), and Strzelce Wielkie (landscape of rural and green areas) confirm the variety of individual issues and topics discussed. Nevertheless, the comparison of these projects also points to similar methods of analysis and planning applying a Polish four-stage landscape designing system: ‘resources—valorization—guidelines—design’. The research results indicate that this system, almost identical to the European ones, can be also useful for planning agricultural areas. In practice, this will allow local authorities to realize the idea of the Green Deal—draw up a more perfect development project for the whole village and simultaneously standardize project documentation. Designers and scientists will achieve better cooperation and fitting spatial planning solutions; this way, interdisciplinary activities and final design will implement the ideas of sustainability and Green Deal.
