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.

The bachelor thesis deals with the geography of sugar beet in the world, in more detail in Europe and also in the Czech Republic. The introductory chapters evaluate relevant literature and characterize sugar beet as a crop. Data is based on data on production and sowing areas from the FAO database, Eurostat and the CZSO. Data from the years 1961 to 2016 are visualized through cartograms, cartodiagrams, graphs and tables. The results are commented on in the background of physical-geographic and time-changing socio-geographical factors affecting the cultivation and processing of sugar beet in individual territories. Total sugar beet production in the world is gradually increasing, but at different pace and fluctuations across countries. Sugar beet is mainly European crop, most currently produced by Russia (a significant increase in the last 15 years), with France, the USA and Germany stagnating (stagnation or small growth in these states), followed by Turkey, Poland, Egypt (significant increase), Ukraine (significant decline) and China. From the NUTS point of view, the biggest concentration of sugar beet production is in north-eastern France, overlapping into the Benelux. The Czech Republic is characterized by fluctuations in total production and concentration of the production locally close to the remaining 7 sugar factories.
