Introduction. The theoretical foundations of the new ecological disciplines "Urban Ecology" and "Phytomeliora-tion" were laid in the mid-80's and 90's of the last century at the Department of Ecology and Landscape Architecture of the Ukrainian National Forestry University, which at that time was headed by Lviv scientist Volodymyr Kucheryavyi famous by his monographs “Green Zone of the City” (Kyiv: Naukova Dumka, 1981) and “Natural Environment of the City” (Lviv: Higher School, 1984).Purpose and methods. The methodological basis of urban ecological research is the ecological-comparative method, which involves gradation ordination with the allocation of four ecological and phytocenotic zones on the territory of cities into the study of the urban ecosystem (suburban forests - city parks – public gardens - street plantings) (V. Kucheryavyi, P. Hnativ, M. Kurnytska, N. Siroochenko, N. Stepanyak, K. Myronchuk, T. Pushkaryova, Yu. Kozak) This approach is used in dissertation research not only by graduate students and applicants of the Department of Ecology and Landscape Architecture of UNFU, but also young scientists of Kyiv, Lutsk and Chernivtsi.Results and discussion. Taking into account the growth of the "recreational boom" among urban residents in the 80's and 90's, scientific researches of park and forest park phytocenoses are developed (V. Kucheryavyi, A. Zhyrnov, Yu. Khrystuk, R. Danylyk, V. Kramarets, N. Lukyanchuk, O. Kaspruk, R. Dudyn, N. Imshanetska, N. Kovalchuk, S. Marutyak, O. Oleynyuk). During this period, visual methods of diagnosing of urban ecosystems state are widely used, which confirm the feasibility of using of ecowedge ordination. The influence of complex urbogenic gradients of the environment on the adaptation processes of living organisms and their significance for the evaluation of the results of woody plants introduction into the urbogenic environment was determined (V. Kucheryavyi, M. Kurnytska, O. Kaspruk, O. Gorbenko, M. Les, V.S. Kucheryavyi, T. Shuplat, N. Gotsiy). Electro-physiological methods of impedance and polar-ization capacity measuring, fluorescence of plastid pigments, temperature gradients of the environment are used for establishing the level of plant viability (V. Kucheryavyi, H. Krynytskyi, V. Mokryi, A. Kuzyk, M. Hozdog, S. Hridzhuk, Yu. Pankivskyi, V. Kucheryavyi, T. Shuplat). Investigations of the phytogenic field of vegetation begin, its role in the formation of the continuum in conditions of urbogenic and manmade devastation is determined (V. Kucheryavyi, V. Popovych, T. Levus, T. Shuplat). The formation of a scientific school on urban ecology and phytomelioration is ensured by the three generations of scientists succession. A significant number of scientists have passed the scientific path from post-graduate student in the 80's - 90's to the candidate or doctor of sciences (P. Hnativ, V. Mokryi, V. Mazepa, S. Myklush, M. Nazaruk, Ya. Henyk, V. Popovych).Conclusions. The authoritative leader of the scientific school on urban ecology, phytomelioration and landscape architecture is Professor Volodymyr Kucheryavyi, who has supervised four doctors and 22 candidates of science. During the years of his scientific activity he published about 300 scientific articles, more than 30 monographs and textbooks. Heading the scientific and methodological commission of the Ministry of Education and Science of Ukraine on environmental education in the 80's and 90's, he started training specialists in "applied ecology" in Ukraine. Thanks to the initia-tive of prof. V. Kucheryavyi scientists of the Scientific School of Urban Ecology, Phytomelioration and Landscape Architecture took an active part in many international projects (V. Kucheryavyi, Ya. Henyk, L. Kalahurka, M. Chernyavskyi, O. Oleynyuk, L. Parkhuts, Z. Sheremeta, S. Melnychuk, V. Popovych, T. Shuplat, M. Fitak, V.S. Kucheryavyi). The scientists worked closely with research teams from Germany, Austria, Belgium, Poland, Slovakia, the Czech Republic, and Norway. Scientific research on urban ecology, phytomelioration and landscape architecture, which began in the 1980s, continues thanks to the succession of scientific generations.

This panoramic view shows how are focused today the relationships between Nature and the City by research scholars and practitioners in North America. In the American context of an “endless city”, it develops four key ideas for a better approach to urban ecosystems: urban ecology, sustainability, new regionalism and landscape urbanism. Urban ecology has emerged as an interdisciplinary approach for understanding the “drivers, patterns, processes, and outcomes” associated with urban and urbanizing landscapes. With the leadership of several American cities, as New York City, Chicago, Seattle and Portland, urban greening efforts based on principles of sustainability are developed. The new perspectives on regionalism are evident in different efforts associated with the megaregion/megapolitan concept: a new geographic unit of analysis and a new scale for planning. This new regionalism represents a movement led by architects and planners involving geographers, demographers, and policy makers. Finally, landscape urbanism is a more design-based approach. Instead of viewing nature in the city, we have begun to understand the ecology of cities: the urban systems are ecosystems. As a result, “nature cannot be used as exterior decoration, but rather as integral to the health and resiliency of human settlement”.

Abstract Urban Agriculture (UA) has emerged as an alternative capable of fostering sustainable relations among the economic, social and environmental spheres in cities. It consists of growing and processing traditionally rural food products in urban zones in consonance with the environmental considerations to promote sustainability. This study set out to analyze the interactions of agricultural activities and the urban ecosystem. A review of the literature and a case study of an Urban Agriculture program developed in the metropolitan area of the city of Rio de Janeiro showed that Urban Agriculture provides considerable ecosystem services, generates income, increases biodiversity conservation and fosters social inclusion, functioning as a mechanism for achieving equilibrium among the components of the urban ecosystem.

Introduction. A public garden or park improvement project should arise from a scientifically grounded study of the territory and proceed from the further development of this object. The aim of the study is to analyze the territory of public gardens in the city of Orel to determine the influence of types of spatial structures on the features of the functioning of a landscape object, to predict the stability of the studied landscape and to assess the dynamics of urban ecosystems based on the state of tree vegetation. Tasks: to analyze the placement and ratio of types of spatial structures on the objects under study; to make an aesthetic and sanitary-hygienic assessment of the landscape; to monitor the state of woody vegetation at the facilities. Materials and methods. For the development of scientifically based design of sustainable urban ecosystems and the reconstruction of urban objects of landscape architecture, a method is proposed for studying the territory of squares along the selected contours of types of spatial structures (TPS), which allows us to identify positive and negative factors affecting the development of design solutions. When analyzing the TPS of the investigated squares, satellite images of objects were used. Results. As studies of the type of spatial structure have shown, in most of the investigated squares, indoor TPS prevails; on average, this type of spatial structure is established on 41.8 % of the square of squares. The location of open and semi-open TPS is haphazard and random. The lowest aesthetic score was established for the closed TPS-21.9 points, which is due to the difficulty of identifying species points in such spaces, poor visibility, inhibition of the growth of not only trees, but also the ground vegetation cover, which in most cases is represented by a sparse grass stand with poor species diversity. When conducting a sanitary and hygienic assessment of various TPSs, it was found that a closed TPS also corresponds to the worst grade (2.5 class), which is associated with a decrease in the suitability for performing sanitary and hygienic functions in weakened and damaged plants. Conclusions. For the majority of public gardens in the city of Orel with a plant age close to the maximum in urban conditions, a closed type of spatial structure is characteristic. The closed type of spatial structure led to a decrease not only in attractiveness, but also in the performed sanitary and hygienic role of landscape architecture objects.

A total of 320 species from 42 families were registered in the herpetobios (stratobiont and epigeobiont beetles) of the urbocenosis of Kharkiv. Among these more than 160 species are recorded for the first time for this metropolis. Four species of ground beetles (Notiophilus germinyi Fauvel, Clivina fossor L., Laemostenus terricola Herbst and Masoreus wetterhali Gyll.) were not listed for Ukraine in the Catalogue of Palearctic Coleoptera. The species Omosita japonica Reitter, 1874 (Nitidulidae) is new for Ukranian fauna. Moreover, 93 species from 17 families are the dominant species (at least in one of the urban ecosystems). Among these, eudominants are represented with almost 20 species, but the number of eudomonants did not exceed ten species in separate urban cenoses. Carabidae (80), Staphylinidae (36), Curculionidae (32) and Tenebrionidae (8 species) dominate both, in species composition and abundance. The total part of these groups reached at least 90% of Coleoptera, recorded in urban-cenosis. Separate species of Silphidae, Dermestidae, Elateridae, Chrysomelidae, Leiodidae, Coccinellidae, Nitidulidae, Scarabaeidae, Histeridae and Lucanidae were sporadically usual in most plots. They accounted almost 9% of the total quantity of all beetles in transformed cenoses. Among these, a greater number of species are found within the families of Scarabaeidae (33), Chrysomelidae (16), Elateridae (14), Histeridae (12), Coccinellidae (11) and Nitidulidae (11), Silphidae (6) and Dermestidae (6). The rest of the families are represented with 1–4 species. All beetles registered in herpetobios belong to three groups. Typical inhabitants of herpetobios prevailed (about 200 species from 22 families, at least 90% of all Coleoptera). The proportion of species sporadically associated with herpetobios (more than 40 species from 10 families) was about 5% of all beetles. Random components of herpetobios are represented by more than 70 species from 10 families, and their total share did not exceed 3% of all Coleoptera. A preliminary taxonomic review of coleopterofauna was carried out in different urbocenoses. The number of species in urbocenosises ranged from 101 (Forest Park) to 124 (urban parks). In other green plantings of the city, the species diversity reached 105–118 species. The number of dominant beetles in different areas ranged from 37 to 60 species.

Urban trees are a source of food resources, habitat and refuge for the biodiversity that occurs in cities. However, the taxonomic identity and status of each plant species as native and / or exotic of in an ecosystem influences its interactions with biodiversity. Wasps are one of the main insects present in terrestrial ecosystems, including urban ecosystems, as components of their biodiversity, playing an important role as biocontrol agents (predators and parasitoids) of populations of other insects associated with urban flora or as phytophagous. Seeking to deepen into the knowledge of the diversity of wasps in the city of Bogotá and their ecological interactions, in this study the diversity of wasps associated with three native and three exotic species frequently in urban parks of the city was evaluated. In total, 22 wasp families and 227 morphospecies were identified. The families Bethylidae, Chalcididae and Crabronidae are recorded for the first time in Bogotá. On the other part, the families Eulophidae, Ichneumonidae and Braconidae were the ones that contributed with the most richness and abundance in this study. Regarding their association with the evaluated plant species, a greater diversity of morphospecies associated with native tree species was found, however, there is an effect of the taxonomic identity and the factor park on the results that are discussed. It highlighting the importance of conserving the native urban flora in green spaces of Bogota’s city, in order to maintain and preserve the diversity of wasps principally with parasitoid and predator habits and thus enhance their role as natural biocontrol agents of insects that affect the health of urban trees, at the same time that ecological processes and functionality of this urban ecosystem would be stimulated.

To tackle urban heterogeneity and complexity, several indices have been proposed, commonly aiming to provide information for decision-makers. In this study, we propose a novel and customizable procedure for quantifying urban ecosystem integrity. Based on a citywide approach, we developed an easy-to-use index that contrasts physical and biological variables of urban ecosystems with a given reference system. The Urban Ecosystem Integrity Index (UEII) is the sum of the averages from the variables that make up its intensity of urbanization and biological components. We applied the UEII in a Mexican tropical city using land surface temperature, built cover, and the richness of native plants and birds. The overall ecosystem integrity of the city, having montane cloud, tropical dry, and temperate forests as reference systems, was low (−0.34 ± SD 0.32), showing that, beyond its biodiverse greenspace network, the built-up structure highly differs from the ecosystems of reference. The UEII showed to be a flexible and easy-to-calculate tool to evaluate ecosystem integrity for cities, allowing for comparisons between or among cities, as well as the sectors/regions within cities. If used properly, the index could become a useful tool for decision making and resource allocation at a city level.

Land Changes

The developments that occur in Manado city, have an impact on changes in existing urban ecosystems and land use. Mapanget sub-district is an area adjacent to the suburbs, when viewed from the ecosystem typology of the land use with plantations, but due to developments in the city center, land changes and land use in the Mapanget district have changed the typology of existing urban ecosystems. The purpose of this study was to analyze land changes and land use in Mapanget sub-district in order to determine the typology of urban ecosystems. The method used is descriptive. To be able to analyze land changes and land use Arc Gis 10.3 software was used with supporting data, namely the 2002-2018 satellite imagery map, 2007-2016 land use map. Based on the results of the analysis, the changes in land use from 2002 was 86.95% reduced to 74.26%. Built land in 2002 was increased from 13.05% to 25.74%. The use of residential lands significantly increases from a land area of 394.09 ha to 733.05 ha. Research shows that the typology of urban ecosystems in Mapanget sub-district consists of absorption typology for around 1395.62 Ha (26.96%), composite ecosystems for approximately 40.54 Ha (0.78%), and production ecosystems around 3740.67 Ha (72.26%). Hence, the typology of production ecosystems is the most dominant changes in land use and more directed to the ecosystem typology of absorption, while land accretion is built at 25.74%.

Modern processes of urbanization in the city of Ternopil are accompanied by an increase in anthropogenic pressure on the natural component, compaction of building and reduction of green areas. Therefore, there is a need to conduct a geoecological assessment of the structure of plantings of the complex green zone of the city, as a factor of ecological safety of the urban ecosystem of Ternopil. Purpose. To assess the structure of the complex green zone of Ternopil city and justify the priority straightways for its optimization. Methods. Descriptive, comparative-geographical, geoinformation, statistical, mathematical, geoecological analysis and optimization modelling. Results. During the geoecological assessment for the structure of the complex green zone of Ternopil city, it was found that its total area is 9684 hectares, of which 2027 hectares – forest-park part and 7657 hectares – forestry part. The structure of the complex green zone of Ternopil city is dominated by forests 64%, water bodies and swamps 18,5% and green planting 17,5%. It is determined that the normative area of the complex green zone of Ternopil city should be 13470 hectares, respectively, the deficit of green planting is 5813 hectares. In order to optimize the complex green zone of Ternopil city and bring its area to the normative indicators, the inclusion of perennial plantations in its structure is substantiated and a model of increasing forest cover due to eroded lands is developed. Implementation of such measures and change of purpose of separate land plots will allow to increase the area of forests in the forestry part of the complex green zone of Ternopil city by 3916 hectares and to reduce the erosion of arable lands by 40%. Conclusions. The optimal structure of the complex green zone of Ternopil city will include 8823 hectares - forests, 1903 hectares - perennial plantations, 1419 hectares - water bodies and swamps, 577 hectares - green planting of common use, 433 hectares - special-purpose green planting and 321 hectares - green planting of restricted use. The total area of the complex green zone of Ternopil city will be 13476 hectares. This optimization model of the complex green zone of the city will contribute to its sustainable development and realization of the main functional potentials.

The expression “urban agriculture” refers to the emergence in many cities of areas cultivated by farmers who distribute the fruits of the land they work in the environs of the zone of production. The movement, born in response to a range of real needs, has become a global phenomenon, and has taken on an organized form in a large number of cities: from Mumbai to Beijing, London, New York, Detroit, São Paulo, Rosario, Vancouver, Tokyo, San Francisco, etc. The urban farming movement, with its production of food, its educational aims and the idea of creating sustainable situations, has been able to take root in many cities and metropolises as it is closely integrated with the urban ecosystem. For the most part it is the poor and women who, working on small farms located both inside and outside the city, are nurturing this politico-cultural movement. Their agricultural settings are creating new and interesting landscapes that need to be analyzed from an aesthetic perspective as well for the influence that they might have on contemporary landscape architecture. The phenomenon could have repercussions on the visual conventions of the urban and suburban environment and even affect the behavior and lifestyles of city dwellers should it develop on a larger scale.
