Water footprint of the cow milk for two types of production systems in the Liberec Region
Hojcsková, Daniela ; Hák, Tomáš (advisor) ; Třebický, Viktor (referee)
The water footprint is a multidimensional indicator which was created to quantify the total volume of freshwater used for various purposes. With the water footprint it is possible to determine the volume and type of water used directly and indirectly during the production in a given place and time. The data related to the water footprints of products are utilized in the evaluation of the international trade with goods, too (a concept of virtual water used for the analysis of water stress export out of the country which imports water-intensive products). The greatest amount of water is used globally in the agriculture, so the agricultural products are the ones with the highest water footprints. The focus of concern is the water footprint of an agriculture production and the aim of this work is to bring the first results regarding the water footprint of the cow milk in the Czech Republic and also to evaluate a methodology of its calculation. Two dairy farms dealing with a market production of milk from the Liberec region were chosen for the research. The farm Rváčov is oriented to an intensive milk production and on the other hand the farm Bzí is a system with mixed elements of extensive and intensive characters of the dairy production. For the comparison of the milk production effectiveness we have...

Mapping of the Litavka catchment using GPS
Hojcsková, Daniela ; Matějíček, Luboš (advisor) ; Brůna, Josef (referee)
This thesis is aimed on the study of Global Positioning System (GPS) and its utilization possibilities in nature sciences such as ecology, hydrology, botany and the others. The main contribution of this work is the investigation of current possibilities of the most accurate data collection by using GPS and their subsequent processing in GIS with focus on small catchment. Other methods of terrain data collection are described and compared with GPS in this work, as well. Practical part of the thesis focuses on characteristics of the locality, technical equipment and data editing gained in terrain. The study locality is the Litavka catchment, which is situated in Brdy. The geographical ground data, were gained from ZABAGED and were completed with results of own measuring in terrain. The output of the thesis is the digital terrain model of upper stream of the Litavka River modified by interpolation. Key words: GPS, DTM, GIS, mapping, catchment, Litavka, interpolation
