Aim. The aim is to assess the intensity of the impact of recreation and vehicle emissions on the Kyiv park ecosystems. Methods. Used methods of ecology, phytoindications. Results. We analyzed the recreational load on 18 park ecosystems within the city of Kyiv. GIS modeling was performed and a gradient of the state ecosystems of Kyiv was built according to the integrated indicator of recreational impact and vehicle emissions. The created map-scheme according to the integrated indicator of the severity of the impact (W) reflects the ecological situation in the studied Kyiv park ecosystems and indicates their significant transformation in the conditions of the megalopolis. The tendency to decrease the number and intensity of manifestations of recreational exposure with increasing severity of exposure (W) is calculated. According to GIS modeling by W and taking into account the prevailing wind directions in the city of Kyiv, it was found that 50% of the studied parks are in critical danger, 30% – in a threatening condition, only the «Pushcha-Vodytsya» park is in a stable condition. The best condition of park ecosystems DShK park, «Peremoha» park; «Babyn Yar», «Nyvky» park, «Lysa Hora» tract, Holosiivskyi National Park. Conclusions. It is important to constantly monitor and preserve natural ecosystems and green infrastructure in large cities. This requires the timely adoption of balanced and correct management decisions both at the level of local authorities and within the state.Keywords: recreation, motor vehicle pollution, urban ecosystem, integrated assessment.

Trees are essential elements of an urban space. The presence of trees in urban areas is not only appreciated as physical attribute, but beyond this, it serves a fundamental function in balancing and conserving urban ecosystem. Especially in tropical countries like Indonesia which receive high levels of solar radiation, trees contribute to the protection of urban areas from the impact of excessive micro-climatic conditions. But, the presence of trees sometimes resulted in the accidents for the residences because of broken branches and human injuries. This situation leads the city to prepare a tree inventory system, which is beneficial in giving the information about tree conditions and thus the information that would be useful for tree maintenance activities. The tree inventory on application for the city of East Jakarta was built for this purpose, comprising a tree inventory and easy access to the database. The application connects the database source with the GIS map, so that the users could retrieve information for each kind of data.

The Impact

The increasing traffic demand has reduced the efficiency of road networks and intensified the maintenance need for mobility and safety, increasing vehicle emissions, reducing air quality, and affecting climate change. To mitigate the negative impacts of work zone activities, a reliable method that can optimize spatio-temporal work zone activities is desirable. Previous studies have aimed to minimize the total cost, including maintenance, user delay, and accident costs, yet the associated environmental impact has been neglected. This study aims to optimize work zone activities using the artificial bee colony (ABC) algorithm, considering the cost of vehicle emissions in addition to the aforementioned costs for an environmentally sustainable optimization. MOtor Vehicle Emission Simulator (MOVES) is applied to calculate emission rates. The results show that the ABC algorithm is very efficient to search for the optimal solution that yields the minimum cost taking into account the well-being of the environment.

The present paper aims to study the impact of Nature Based Solutions (NBS) on the urban environment. The Surface Urban Energy and Water balance Scheme (SUEWS) is used to quantify the impact of NBS in the city of Heraklion, Crete, Greece, a densely built urban area. Local meteorological data and data from an Eddy Covariance flux tower installed in the city center are used for the model simulation and evaluation. Five different scenarios are tested by replacing the city’s roofs and pavements with green infrastructure, i.e., trees and grass, and water bodies. The NBS impact evaluation is based on the changes of air temperature above 2m from the ground, relative humidity and energy fluxes. A decrease of the air temperature is revealed with the highest reduction (2.3%) occurring when the pavements are replaced with grass for all scenarios. The reduction of the air temperature is followed by a decrease in turbulent sensible heat flux. For almost all cases, an increase of the relative humidity is noticed, accompanied by a considerable increase of the turbulent latent heat flux. Therefore, NBS in cities change the energy balance significantly and modify the urban environment for the citizens' benefit.

Introduction. Providing the natural frame of the city as a sustainable system of landscaping and water areas in the urban environment is one of the tasks aimed at preserving the natural frame of the urban environment. The article focuses on the influence of the recreational load on the natural-anthropogenic territorial complex (PATC) located in the North-Eastern administrative region of Moscow. To ensure sustainable development of natural areas, the ability of the components of the natural environment to self-heal under conditions of anthropogenic impact is of particular importance. Taking into account the increase in residential and industrial areas located in close proximity to natural zones, the anthropogenic impact on natural complexes is increasing. First of all, this affects the recreational areas of park zones, where the potential recreational load begins to exceed the stan­dardized and causes degradation of green spaces and disruption of the urban ecosystem. Recreational load affects the state of the natural complex of the city, and its value is determined by the planning structure of urban development. While ensuring the safety of city parks, it becomes necessary to work with complete and reliable information, which can only be obtained through research. The practical aspect of scientific research, considered in the article, includes the results of the analysis of the impact of anthropogenic load on the natural-anthropogenic territorial complex of the park - the estate “Ostankino”. Materials and methods. The paper uses various attributive information collected from open sources and based on the results of field work by the authors, legal documents, and various cartographic materials. The calculation of potential visitors was carried out by a simple calculation method, followed by the use of the Microsoft Office Excel software product to compile the time dependencies of the visit. Results. On the basis of the conducted research, the excess of the normative value of the recreational load of the territory of the Ostankino estate park in Moscow was revealed and graphs of the dependence of the visit on the time intervals were constructed. Conclusions. The increased rate of population inflow and environmental pollution leads to the transformation of the ecological framework of the city.

Abstract Protected areas are the key elements of the green infrastructure and environmental city frame that provide variety of ecosystem services to the people as well as serve as the centers of investment attraction. The total area of the protected lands of Khabarovsk is 583.57 ha (1.5% of the city area): 5 protected ones of regional significance, 24 areas of local significance. There are 117 species observed in the dendroflora of all protected areas, which is relatively close to the natural biodiversity indicator. The reserve for expanding the protected areas network in Khabarovsk is mainly represented by the lands of the Russian Ministry of Defense, floodplain lands, the adjacent areas to the water protection zones of small rivers in the city, and ecologically restored technogenic sites. In addition to the forest type areas this will permit to create water and meadow-marsh protected plots, which meets the representativeness criteria of the natural ecosystems of the Amur River Region. The case study of a protected area called Orekhovaya Sopka, allows seeing that keeping record of the ecosystem services increases both the economic and the environmental values of the territories. The results may be applied in: municipal management.
