The combination of landforms under urban areas of Kyiv plays a decisive role in the formation and development of the city. Various morphosystems of the city has experienced significant transformations over the long-lasting history of Kyiv, which find the reflection in the modern terrain of the cityGeomorphological excursions as a kind of scientific and cognitive activity became one of the ways to explore the relief of the city, learn the interaction of the geomorphological component of the urban landscape and the development of the city at its various historical stages. It’s a promising component of the study program for Earth Science students as long as it’s the best method for studying typical for urban geosystems processes and phenomenons. Excursions ought to fulfill several functions such as scientific propaganda, popularization of geomorphological science, have informative and educational value. According to the main methodological principles, creating a new excursion demands following specific steps, including selection of the goals and purposes of the tour, major and minor destinations due to the topic of the tour, designing tour routes and organizing the final text materials for the tours. There are four geomorphological tours represented in the article. The main purpose of the first excursion is to determine the impact of the landforms features on the construction of Kyiv fortification and to highlight the landscape transformations of the explored areas. The scientific aspect of this route includes exploration of the remnants of the great Kiev retrenchment, the signs of the landslide processes on the right bank slopes of Dnipro river. The second tour is aimed at studying of the transformation of Kyiv ravens - Babyn Yar and Repiiahiv yar , in particular. Due to its purpose of getting students acquainted with the influence of the natural conditions of the area on the course of historical events, the main objects are virgin original landscapes of the ravens as well as transformed areas, the drainage of the stream Babyn Yar and the evidence of an industrial disaster - Kureniv tragedy. The third excursion, highlighted in the article, is aimed at revealing the transformation of the Goloseivsky Forest and provides an overview of the natural and man-made forest landscapes, the influence of the geological and geomorphological conditions of the territory on its economic development, planning and development of the city. The fourth tour aims to provide an insight into the unique natural features and peculiarities of the Kiev hills’ history, as a center of the city formation. The tour is a great way to increase knowledge of the influence of geomorphological conditions on the development of Kyiv at different historical stages, the differentiation of functional parts of the city due to the landforms contrast. Geomorphological excursions demonstrated in the article are the most representative as long as they provide a comprehensive understanding of the relief of the Kiev urban sphere, help to track the development of the city throughout all historical epochs, learn geomorphological factors and their impact on the development of different parts of Kyiv.

From the analysis of the urban landscape, the investigation focuses on the role of commerce in historical urban areas and their relations at present with the landscape, in relation to the preservation of heritage values. Trade plays an essential role in historical urban areas, both in its past and in its present, since it is part of the urban landscape, creating it and modifying it but also preserving it. The historical protected urban areas contain diverse elements that reflect the impact of the commercial activity existing in the city throughout history. At present, the urban landscape of commercial activity is made up of a multiplicity of typologies and formats. Trade interacts with the historical landscape in which it is developed and the heritage values of that landscape, using them to strengthen its strategies of attraction, differentiation and sales. The shop owners contribute to the preservation of historic urban areas by maintaining the commercial function in them. Therefore, we affirm that the role of commercial activity in the preservation of urban protected areas is essential. However, further research is needed because the scientific community specializing in the management of cultural heritage has not deepened in this aspect.

Recently, the number of published works devoted to the processes of synanthropization of fauna, is growing like an avalanche, which indicates the extreme urgency of this theme. In our view, the process of forming devices to coexist with human and the results of his life reflects the general tandency of the modern nature evolution. Urbanization is characteristic for such a specific group of animals like amphibians, the evidence of which are numerous literature data. Many researchers use this group to assess the bioindicative quality of the environment. For this aim a variety of indicators are used: from the cellular level of life of organization up to the species composition of the group in different territories. At the same time, the interpretation of the results is not always comparable for different areas and often have significantly different interpretations by experts. Urban environment, primarily due to the contamination is extremely aggressive to amphibians. As a consequence, the urban populations of amphibians may be a change in the demographic structure, affecting the reproductive ability of the population, the disappearance of the most sensitive species or individuals, resizing animals, the appearance of abnormalities in the development, etc. At the same time play an important amphibians in the ecosystems of cities, and some species in these conditions even feel relatively comfortable. Therefore, it is interesting to understand the mechanisms of self-sustaining populations of amphibians in urban environments. To assess the impact of natural and anthropogenic factors on the development of amphibian populations were used cognitive modeling using the program Vensim PLE. Cognitive map of the model for urban and suburban habitat conditions were the same. The differences concerned the strength of connections between individual factors (migration, fertility, pollution) and their orientation. In general, factors like pollution, parasites, predators had negative impact on the population, reducing its number. The birth rate, food and migration contributed to raising number of individuals. Some of the factors affected on the strength to of each other as well: the majority of the factors affected the structure of the population, had an influence on the fertility. Thanks to it the model reflects the additive effect of complex of factors on the subsequent status of the population. Proposed and analyzed four scenarios differing strength and duration of exposure. In the first scenario, a one-time contamination occurs and not subsequently repeated. The second and third scenario assumes half board contamination, 1 year (2 scenario) and two years (scenario 3). In the fourth scenario, the pollution affected the population of amphibians constantly. In accordance with the results of simulation, much weaker than the natural populations respond to pollution - have them as an intensive population growth and its disappearance at constant pollution is slow. Changes to other parameters of the model showed that this pollution is the decisive factor -only the constant action leads to a lethal outcome for the populations. All other components of the model have a corrective effect on the population dynamics, without changing its underlying trand. In urban areas due to the heavy impact of pollution maintaining the population is only possible thanks to the migration process – the constant replenishment of diminishing micropopulations of natural reserves. This confirms the assumption that the form of existence metapopulations lake frog in the city. In order to maintain the number of amphibians in urban areas at a high level it is necessary to maintain existing migration routes and the creation of new ones. Insular nature of the placement of suitable habitats in urban areas causes the metapopulation structure of the types of urbanists. Therefore, the process of urbanization is much easier for those species whicht are capable of migration in conditions of city. In the initial stages of settling the city micropopulationis formed by selective mortality of the most susceptible individuals to adverse effects. In future, maintaining the categories of individuals is provided mainly due to migration processes metapopulisation form of the species of existence is supported). It should be noted that the changes in the previous levels are always saved in future. In the case of reorganizations of individuals we of morphology can assume the existence of extremely adverse environmental conditions that threaten the extinction of the micropopulations.

The assurance of drinking water supply is one of the biggest emerging global challenges, especially in urban areas. In this respect, groundwater and its management in the urban environment are gaining importance. This paper presents the modeling of nitrogen load from the leaky sewer system and from agriculture and the impact of this pressure on the groundwater quality (nitrate concentration) in the urban aquifer located beneath the City of Ljubljana. The estimated total nitrogen load in the model area of 58 km2 is 334 ton/year, 38% arising from the leaky sewer system and 62% from agriculture. This load was used as input into the groundwater solute transport model to simulate the distribution of nitrate concentration in the aquifer. The modeled nitrate concentrations at the observation locations were found to be on average slightly lower (2.7 mg/L) than observed, and in general reflected the observed contamination pattern. The ability of the presented model to relate and quantify the impact of pressures from different contamination sources on groundwater quality can be beneficially used for the planning and optimization of groundwater management measures for the improvement of groundwater quality.

The Impact

Scarcity and competition for good quality and potable water resources are limiting their use for urban landscape irrigation, with several nontraditional sources being potentially available for these activities. Some of these alternative sources include rainwater, stormwater, brackish aquifer water, municipal reclaimed water (MRW), air-conditioning (A/C) condensates, and residential graywater. Knowledge on their inherent chemical profile and properties, and associated regional and temporal variability, is needed to assess their irrigation quality and potential short- and long-term effects on landscape plants and soils and to implement best management practices that successfully deal with their quality issues. The primary challenges with the use of these sources are largely associated with high concentrations of total salts and undesirable specific ions [sodium (Na), chloride (Cl), boron (B), and bicarbonate (HCO3−) alkalinity]. Although the impact of these alternative water sources has been largely devoted to human health, plant growth and aesthetic quality, and soil physicochemical properties, there is emergent interest in evaluating their effects on soil biological properties and in natural ecosystems neighboring the urban areas where they are applied.

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.

This thesis discusses a method of analysing the input of interventions in a building's site design, all of which affect the heat island effect, bio-diversity and hydrology of urban areas. Existing standards from Toronto, Vancouver and Berlin have been researched and analysed. This paper presents an evolution of a method called biotope area factor used in Berlin, Germany. A synthesis of the approach of all three systems was considered and distilled into the key points which were then incorporated into the proposed method. In addition to the impact of an individual building, it also includes the impact from the adjacent street area. The final components of this thesis are the application of the method developed to an urban area in the city of Toronto and results showing the impacts on architectural design from site rating systems.

Previous research has assessed the potential of solar energy against possible demand; however, the sustainability issues associated with the use of large-scale photovoltaic deployment in urban areas have not been jointly established. In this paper, the impact of photovoltaic energy in the total urban energy mix is estimated using a series of indicators that consider the economic, environmental and social dimensions. These indicators have been previously applied at the country level; the main contribution of this research is applying them at the urban level to the city of Cuenca, Ecuador. Cuenca is close to the equatorial line and at a high altitude, enabling this area to reach the maximum self-supply index because of the high irradiation levels and reduced demand. The solar potential was estimated using a simple methodology that applies several indexes that were proven reliable in a local context considering this particular sun path. The results demonstrate that the solar potential can meet the electric power demand of this city, and only the indicator related to employment is positive and substantially affected. The indicators related to the price of energy, emissions and fossil fuel dependency do not change significantly, unless a fuel-to-electricity transport system conversions take place.

The city has proved to be the most successful form of human agglomeration and provides wide employment opportunities for its dwellers. As advances in robotics and artificial intelligence revive concerns about the impact of automation on jobs, a question looms: how will automation affect employment in cities? Here, we provide a comparative picture of the impact of automation across US urban areas. Small cities will undertake greater adjustments, such as worker displacement and job content substitutions. We demonstrate that large cities exhibit increased occupational and skill specialization due to increased abundance of managerial and technical professions. These occupations are not easily automatable, and, thus, reduce the potential impact of automation in large cities. Our results pass several robustness checks including potential errors in the estimation of occupational automation and subsampling of occupations. Our study provides the first empirical law connecting two societal forces: urban agglomeration and automation's impact on employment.

AbstractCities develop around industry, markets and transport links. Dublin in the nineteenth century was similar, but additionally the north-west of the city developed around the expansion of a complex of institutional buildings for the reception, confinement and welfare of the poor and sick. This article argues that these institutions were implicit in the development of the modern city in the same way as industry and commerce. The physical development of the buildings altered and defined both the streetscape and, over time, the social identities and historical communities in the locale, in the same way that industrial development defined urban areas.
