Opis:
For the last 20 years researchers have tried to create new approaches of managing urban ecosystem by using remote sensing methods. The authors estimated the normalized vegetation index (NDVI) and moisture index (NDMI) indices of Kyiv and propose an approach which can be used for estimation vegetation of other cities. The aim of the study was to assess the indicators of NDVI and NDMI in Kyiv for the last 5 years. The authors consider the NDVI index as an important ecostabilizing component of the urban ecosystem, as well as an indicator of the well-being citizens in a modern city. The study used space images of the Sentinel-2 satellite system with resolution of 10×10 m and 10×20 m. The images were decrypted using the Sentinel Hub platform which updates the data-base daily. The paper presents the results of correlation analysis using Statistica-6.0 software and demonstrate the close relationship (r = 0.73, r2 = 0.55) between NDVI and NDMI. Thus, the statistical results of the study confirm a strong correlation between photosynthetic activity of plants and indicators of their water content by satellite imagery which allows using modern satellite technologies to assess the functional state of the urban vegetation. The changes in the length of active vegetative growth period were identified by NDVI and NDMI. The results of the research expand the directions of the methods of monitoring the condition of the urban vegetation cover in the aspect of applied landscape research.

We investigated the status of invasive exotic plants disturbing the ecosystem of the Seoul metropolitan area and examined the management of such plants. We selected our study sites based on those used in previous studies and on information in databases. All flora were classified into 57 families and 211 species; we evaluated 253 plant communities. The representative, invasive exotic species were Sicyos angulatus, Lactuca scariola, Ambrosia trifida, Ambrosia artemisiifolia, and Eupatorium rugosum. Stands of A. trifida ranged in area from 214 to 16,882 m2 and were present in riparian zones, road and forest edges, slopes, and other open habitats at all sites, covering an average of 37.87% of all study areas. In Gwangju, Ansan, and Anyang cities and in Yeoncheon-gun, A. trifida coverage was >50%; the total mean coverage was near-continuous along the Han and the South Han rivers, broken only by cliffs in some riparian zones, and anthropogenic constructions. A. trifida and S. angulatus require careful management because of extensive growth, shading, and twining. The biodiversity of native species may be conserved by physical eradication of these plants. We describe the extents and distribution patterns of these two representative invasive exotic species in the enormous urban ecosystem of Seoul.

Opis:
Integrating the ecosystem services (ES) concept into land-use planning has been the focus of researchers in recent years. Forwarding this objective in order to foster human well-being, urban and regional planning became the focus of research efforts. Furthermore, governance research has been beneficial in studying the coupling of ecosystem services and planning processes. Thus, in this explorative case study we have analysed the governance of urban and regional planning in two case studies – Rostock and Munich – in order to gain insights about the role and value of ecosystem services among planning actors. We conducted semi-structured interviews to identify relevant parameters to facilitate integrational approaches of ecosystem services into decision-making in the context of cross-sectoral urban and regional planning. Based on our results, we argue for a change of the perspective of ES within planning practice. Instead of ecological or economic endeavours, the contribution of ES to human well-being should be in the centre of attention. Human well-being as an overarching aspiration may have the potential to shift ecosystem services from sectoral to cross-sectoral planning.

Opis:
The article studies the problem of assessing the quality of atmospheric air in the green areas of the metropolis. The aim of the work is to compare the data obtained by the biomonitoring method with information from unified state environmental monitoring system (USEMS). The sample object of the study is a Udelny park located in the Primorsky district of the city of St. Petersburg. The objectives of the study include the analysis of atmospheric pollution of the Udelny Park by the method of bioindication, comparison of the data obtained with the general telephone indicators, as well as with information from the nearest USEMS posts. When studying the object, the method of V.M. Zakharov was used to study the fluctuating asymmetry of the leaf plates of the hanging birch (Betula pendula Roth.). The site between Udelny Ave., the Vyborg railway line, Testers Ave. and Kolomyazhsky Ave. with an approximate area of 18 hectares was chosen as a model site. The assessment was carried out on 12 pickets, at each 100 samples of leaf plates were taken in total. For comparison, data were obtained from a stationary observation post for the state of atmospheric air pollution, information on the content of pollutants in the air of the Primorsky district. The study found that the quality of atmospheric air in the territory is low. In part of the pickets, the value of the fluctuating asymmetry index was more than 0.054, which corresponds to the V score (critical pollution). These data are generally correlated with information about air pollution in St. Petersburg. Nevertheless, the state of the environment is assessed by the chosen method more critically. This is due to the fact that the biomonitoring method studies pollution from the point of view of direct impact on the ecosystem, taking into account, among other things, the cumulative effect. The result makes us to conclude that it is more correct to use an integrated approach, combining both methods, to assess the stability of urban ecosystems and the quality of the environment in them. It is important to separate information about the quality of the atmosphere in green areas from general data on residential areas.

Opis:
The purpose of this paper is to indicate the valuation importance of externalities derived from the urban ecosystem services (UES) in terms of their applicability in the appraisal process of urban regeneration projects co-financed from European funds. Specifically, it examines the impact of UES on the project’s economic performance, and thereby on human quality of life. Using the discounted cash flow method, this paper estimates the project’s economic performance indicators including the identified UES upon their prior valuation. The valuation was carried out on the basis of the benefit analysis, contingent valuation method – “willingness to pay” – and benefit transfer method, as recommended by Bernaciak, Wojcieszak (2014) and Zawojska et al. (2016). Results show that urban projects including UES are characterised by the higher values of the economic performance indicators and they should be assessed higher than projects with little or no UES because of their stronger contribution to the sustainable development of urban areas. In spite of the fact that there are limitations due to the UES valuation techniques used in the study, the presented approach could be an important tool for the project’s appraisal.

Opis:
In recent years, great emphasis has been placed on the implementation of the principles of sustainable construction and environmental protection. Decreasing amount of natural resources and increasing amount of industrial waste have made it necessary to produce products with the use of recycled materials. A number of studies conducted allow us to state that artificial aggregates, industrial ashes and waste from the wood industry are widely used in the production of construction products. The aim of the article is to show that the use of waste materials will allow to reduce the weight and absorbability of concrete chips by using artificial aggregate type Certification and improve the thermal insulation of products through the use of sawdust and wood chips. A 2 factorial experience with a rotational experimental plan was planned. The article presents the results of physical and mechanical properties tests and statistical interpretation of the obtained results.

Opis:
Wzrost poziomu komfortu ludzi w miejskich ekosystemach społecznych doprowadził do tego, że coraz więcej czynników może wpływać na równowagę systemu „społeczeństwo-środowisko naturalne”, a tym samym na zdrowie ludzi. Wśród nich szczególne miejsce zajmuje wpływ promieniowania elektromagnetycznego (EMR) na organizm człowieka. W każdym punkcie na testowanej powierzchni pomierzono natężenie pola elektrycznego (E), natężenie pola magnetycznego (H) oraz gęstość powierzchniową strumienia energii (μ). Do pomiarów wykorzystano tester Tenmars RF three-Axis Field Strength Meter TM-195. Na potrzeby badań medycznych i ochrony środowiska w wybranych punktach badanej powierzchni aglomeracji Iwano-Frankowska przeprowadzono, w jednym czasie, pomiary natężenia pola elektrycznego (E), pola magnetycznego (H) i gęstości powierzchniowej strumienia energii (μ). Przeprowadzono pomiary akcji serca (HR), skurczowego ciśnienia tętniczego (S) i rozkurczowego ciśnienia tętniczego (D).
The level increase of comfort of the people in the urban social ecosystems has led to becoming a greater number of factors that may affect on the balance of the system “society-natural environment” and, consequently, on the people health. Among them the special place takes the influence of the electromagnetic radiation (EMR) on the human body. At each point of the test area the intensity of the electric field (E), the intensity of the magnetic field (H) and the intensity of the surface density of energy flow (μ) were measured. For the measurements were used tester Tenmars RF three-Axis Field Strength Meter TM-195. For the medical and environmental research at selected points of test area of urban area of Ivano-Frankivsk city at one time with intensity measurements of electricfield (E), magneticfield (H) and the surface density of energy flow (μ) conducted measurements of heart rate (HR), systolic arterial pressure (S) and diastolic arterial pressure (D).

The concept of ecosystems services has become an important model for linking the functions of ecosystems to human welfare. The aim of this paper is to identify ecosystem services generated by green areas within the urban area, classify and value them. "Ecosystem services" refers to components of nature, directly enjoyed, consumed, or used to yield human well-being (Boyd, Banzhaf 2007). This definition advances the ability to use ecosystem services as a practical measurement tool.

Opis:
Water dependent ecosystems are habitats most vulnerable to urbanization pressure. There are not many such habitats in Warsaw. Those which remained are mostly dewatered sites existing within green areas such as parks. Habitats with peat and moorsh soils have a unique value, thus there is a rational need for detailed research and evaluation to preserve them. This paper is a case-study of two different water dependent ecosystems, localized within the boundaries of Poland’s capital city, both remaining under strong urbanization pressure. Different actions were undertaken to preserve those habitats, with differing results. We examined tendencies of vegetation during recent 20–30 years, basing on fl oristical data. In the areas, where water regime has been disrupted, like Natural Landscape Complex “Olszyna” a significant decline of plants rare in the scale of Warsaw is being noticed. Habitats not disturbed by human interference like ”Zakole Wawerskie” do not suffer significant changes, even an increase of rare plants was marked. Presence of water dependent ecosystems is also correlated with population density. In the areas of highest population density these habitats occur seldom, are of a small size and have simplified border zones. The only areas within Warsaw borders where water dependent ecosystems maintained are the urban parks. In the last decades a progressive decline of wetlands is being noticed, which was also confirmed in this study. The only real chance for further preservation of this areas is to create biodiversity hotspots and good recreation infrastructure.
Ekosystemy hydrogeniczne ze względu na swoją silną zależność od warunków hydrologicznych należą do najbardziej wrażliwych na presję urbanizacyjną. W Warszawie niewiele jest takich obiektów, a te, które przetrwały, są to najczęściej odwodnione siedliska znajdujące się na terenach parków miejskich i zieleńców. Ekosystemy związane z glebami torfowymi i murszowymi charakteryzują się wysoką wartością przyrodniczą, istnieje więc potrzeba ich wnikliwego badania oraz wyceny, aby efektywnie chronić te cenne obszary. Niniejsza praca stanowi studium dwóch przypadków ekosystemów hydrogenicznych, znajdujących się w granicach Warszawy i podlegających silnej presji urbanizacyjnej. Zostały podjęte różne działania, by przeciwdziałać negatywnym procesom zachodzących w tych obiektach, z odmiennym skutkiem. Na podstawie danych florystycznych badano tendencje zmian roślinności w ostatnich 20–30 latach. W obszarach, gdzie zaburzony został reżim hydrologiczny, jak na przykład Zespół Przyrodniczo-Krajobrazowy „Olszyna”, zanotowano spadek udziału gatunków roślin rzadkich w skali Warszawy. W siedliskach niedotkniętych silnie przez antropopresję, jak Zakole Wawerskie, nie zanotowano istotnych zmian w składzie gatunkowym, stwierdzono natomiast zwiększenie się liczby gatunków rzadkich w skali Warszawy. Zauważono również pośredni wpływ gęstości zaludnienia na siedliska hydrogeniczne – w obszarach najsilniej zaludnionych występują one najrzadziej, charakteryzują się też niewielkim rozmiarem i uproszczoną linią brzegową. Obszarami, w których ten typ ekosystemów przetrwał w przestrzeni Warszawy, są jedynie parki miejskie. W ostatnich latach obserwuje się zanikanie mokradeł, co zostało również przedstawione w niniejszym studium. Szansę na podtrzymanie istnienia ekosystemów hydrogenicznych upatruje się w tworzeniu tzw. ostoi różnorodności biologicznej oraz dobrze przygotowanej infrastruktury turystycznej.

Opis:
The need for improvement of the environment quality at the territory of cities is directly conditioned by its impact on the health of humans. At the same time humans are not the only residents of urban ecosystems, but they are also inhabited by other organisms, using city as their habitat. The growth of cities is a stable trend of the modern times and it comes into conflict with wildlife living activity and quality of environment. Sustainable development of cities is impossible without environment protection, economic progress and benefits for local communities, therefore the creation of protected areas groups within the city of Kyiv is offered as an instrument for biodiversity support and urban ecosystem stabilization. The most important requirements to the sites to be included into the system of protected areas have been formulated. The first two cores are developed based on small lakes, which are characterized with environmental, recreational and wildlife support potential. The benefits from the creation of the urban network of protected areas have been defined for urban ecosystem and social and economic situation in the city.

Opis:
This research at the Wilanów Palace, Warsaw, assesses urban greenery’s cooling impacts in a cultural heritage site using remote sensing and on-site measurements, highlighting vegetation’s importance in urban climate control. The study combines soil temperature data, UAV thermal imagery, leaf area index (LAI), LiDAR, and NDVI analyses. Findings demonstrate a strong link between vegetation density and temperature: UAV land surface temperature (LST) ranged from 26.8° to 47.5°C, peaking at 72°C, while ground-based temperatures were between 19.5° and 29.2°C, lowest in dense vegetation areas. The statistical analysis confirmed significant temperature differences across vegetation types, with higher LAI areas showing lower temperatures. These results validate the cooling effect of dense vegetation, emphasizing green spaces’ significance in urban climate regulation within cultural heritage sites. The study informs sustainable urban design and conservation, underlining the critical role of vegetation in improving urban microclimates.

Opis:
The urban environment is stressful and trees experience multiple stresses, including drought, flooding, and extreme heat, all of which are likely to increase under future climate warming and increasing urbanisation. In the selection of tree species to maximise ecosystem services, tolerance to site characteristics such as flooding and severe drought is of critical importance. This study evaluated the suitability of a rare species, Alnus subcordata C.A. Mey (Caucasian alder) from the Hyrcanian forests of southern Azerbaijan, for its functionality as an urban tree. A total of 48 pot-grown, two-year-old saplings of A. subcordata were tested in a greenhouse experiment using a complete randomised block design. Each block contained four replicates of three treatments (waterlogging, drought, control), with 16 plants per treatment. Height differences between treatments were measured, and water status was estimated by determination of midday leaf water potential (ΨL) and stomatal conductance (gs ). To estimate drought tolerance reaction in the treatments, leaf water potential at turgor loss (ΨP0) was used together with broken-stick modelling of water status over time. There was a significant difference in tree height between the different treatments. In the drought treatment, A. subcordata plants showed no height increase, while plants in both the waterlogged and control treatments increased in height during the nine-week experiment. Over 63 days of flooding, plant water status was slightly more negative in the waterlogging treatment, but did not deviate essentially from the control. In the drought treatment, plant water status rapidly deviated from the control. There was a significant difference in ΨP0 between treatments, with drought-treated plants showing the lowest value (−2.31 MPa). This study demonstrated that A. subcordata has limited tolerance to drought and seems to rely more on water loss-avoiding strategies. However, the species may be usable at periodically waterlogged sites, due to its high tolerance to flooding. It could therefore be recommended for wet urban environments and stormwater management facilities, for which reliable guidance on suitable trees is currently lacking.
