Design of urban area using advanced technologies
Špaček, Jan ; Apeltauer, Tomáš (referee) ; Remeš, Josef (advisor)
This thesis focuses on the design of urban areas in regards of the air flow and the creation of Urban Heat Islands. It reviews basic aspects influencing the design of streets. Every building, tree, or obstacle obstructs the air flow and creates the wind shadow, where the air pollution increases. It also creates areas of higher wind speed, in which public comfort is reduced. By understanding the importance of this process and by implementing it into the urban planning process, using advanced technology we can create healthy urban environment.

Response to abiotic stress in plants growing in green façades of temperate urban environment
Hrochová, Růžena ; Lhotáková, Zuzana (advisor) ; Havelková, Lenka (referee)
With increasing urbanization the temperature of cities is increasing and an effect of urban heat island arises. Vegetation, particularly vertical greenery systems: facades and walls, is mitigating urban heat island and reducing temperature. The aim of this work was to define these systems, their effects on the urban microclimate, to create an overview of the most used plants for greenery systems and to summarize their reactions to abiotic stresses of cities in a temperate region. Mediterranean studies were used in this work due to the scarcity of temperate climate research, which results could become valuable with climate change. Selecting proper vegetation can be done using habitat template, plants that are acclimated or adapted to the urban environment. Plants affect the urban microclimate through shading and transpirational cooling, which ideally contribute to reducing the heat island effect with optimal irrigation. Stressors followed in this work were drought, high temperature and irradiance, air pollution and salinity. To all these stressors plants reacted with limiting physiological functions and reducing growth. The common reaction was a decrease photosynthesis rate and chlorophyll content. Ractions of plants of vertical greenery systems to different stressors and their combinations are...

Fenomén urban gardening
Kozáková, Petra
The diploma thesis aims to introduce the phenomenon of urban gardening and identify the benefits provided by the urban environment and society. The benefits of urban horticulture are identified as a possible adaptation measure concerning ongoing climate change. The types of urban gardening, approaches and possibilities of its application in practice are presented. Trends in urban horticulture and individual aspects are described on the example in the Czech Republic, the Netherlands and Sweden. The specific benefits of urban gardening were expressed on a specific example of a community garden in Brno using CBA analysis (cost-benefit analysis). The author worked here with data provided to her directly from the staff of the selected community garden and also based on the "willingness to pay" method, in which she addressed 100 respondents. The result of the CBA analysis was an evaluation of the community garden project, which determined the return on investment and its net present value.

Vliv vegetace na letní teplotní extrémy ve městech hodnocené z pozemních a leteckých dat
ROHÁČ, Václav
This thesis examines the effect of surface types and vegetation types on ambient temperature during summer temperature extremes. The theoretical part targets the topics of remote sensing, electromagnetic radiation, urban and global climate. Within the practical part, 3 areas of interest were selected from aerial hyperspectral data from the territory of the statutory city of České Budějovice, each representing a different part of the city in terms of land use. By means of data analysis, graphs showing the influence of the relative representation of the variant surfaces on the temperature were created using the linear regression method. From the maps of tree species occurring in the parks of the first two areas, the most abundant species were selected and the average temperature within 2 meters of them was examined. The thesis also includes an evaluation of a questionnaire answered by city residents on the topic of preferences and knowledge about the urban green space.

Časové změny vlivu vegetačního krytu na místní klima intravilánu obce pomocí metod dálkového průzkumu Země
NÁROVEC, Václav
The diploma thesis deals with changes in vegetation indices and surface temperatures of previously undeveloped peripheral areas of České Budějovice and its immediate surroundings, which were built up after 1990. Areas that were undeveloped before 1990 and spread over either permanent grassland or arable land with agricultural crops. These areas are divided into four types - industrial areas, service areas, residential areas of multiapartment houses and residential areas of solitary family houses. The work uses Landsat satellite images for the years 1990, 1993, 1999, 2006, 2010, 2015 and 2020. The studied areas were examined in the period before construction, just after construction and with a distance after construction. In the period before the transformation (1990), there were high values of vegetation indices NDVI (Normalized Difference Vegetation Index), SAVI (Soil Adjusted Vegetation Index) a NDMI (Normalized Difference Moisture Index) and low values of surface temperatures in most of the studied areas. However, during the construction, the vegetation decreased and thus the values of vegetation indices decreased and the surface temperatures increased. Subsequent improvements were observed in areas with multi-apartment and family houses, where the vegetation of parks and residential gardens grew after a certain time. In the vicinity of the industrial area and service areas, where vegetation did not grow, the values of the monitored indices remained low.

Vliv vegetace na teplotní režim městského prostředí
SEDLÁČEK, Jan
This thesis is aimed at the influence of vegetation on temperature in urban areas. In order to research this influence, a thermal camera was used to measure surface temperature in a number of places in České Budějovice. The results show that vegetation not only reduces thermal amplitudes, but also influences the temperature of surrounding surfaces (up to a few metres). Lower temperatures compared with conventional surfaces were reached during the summer days not only by trees, but also by less common green structures, such as ornamental plants or a green roof and wall. According to the results, some suggestions were brought in order to increase the effectivity of green infrastructure and to reduce the Urban Heat Island effect.

Study of Urban Heat Island with using of remote sensing investigations
Doležalová, Anežka ; Žák, Michal (advisor) ; Huszár, Peter (referee)
Modern times bring considerable urbanization which represents the development and extension of cities. An urban environment is very different in structure from the rural one and the natural landscape. The differences are shown in various types of climatic observations and they also lead to a phenomenon called Urban Heat Island. The city appears as an island with higher temperature compared to the surrounding rural areas. Eumetsat satellites called MFG and MSG with the MVIRI and SEVIRI instruments are used for the analysis of SUHI, the measurement of which is processed by the application of various algorithms. 1

Physiological responses of woody species to urban environment
Petrouová, Lenka ; Lhotáková, Zuzana (advisor) ; Lipavská, Helena (referee)
Trees are an important functional element in urban ecosystems. The urban environment has a number of abiotic stress factors for trees and their interactions are based on the overall physiological condition of the trees. Abiotic stress factors include air pollution, space constraints, reduced water availability, increased temperature, and precipitation. In addition to abiotic factors, trees in the city face stressful conditions brought on by climate change, which are increasing in severity and have a measurable impacts on urban tree growth. Climate change is manifested mainly by elevated air temperatures, changes in quantity and distribution of precipitation, and increased concentrations of carbon dioxide in the atmosphere. This bachelor's thesis is focused on the responses of selected woody species in urban environments and their adaptive abilities in the context of changing climatic conditions. Growth is the main observable response of woody species to environmental changes. In particular, increased growth has been recorded in relation to rising temperature and carbon dioxide levels. Specific differences between woody species in functional parameters can be utilized to improve quality of life in human environments Trees are highly valuable in urban ecosystems and perform a range of functions,...
