Water footprint of consumption of the Czech households
Možíšová, Jana ; Ščasný, Milan (advisor) ; Turdaliev, Salim (referee)
Since the human society rises the requirements on environment it is important to find ways to mitigate the pressure. One of the possible important aspects could be consumption behaviour of individuals. In thesis we examine the water footprint connected to consumption of Czech households. Using the hybrid input-output analysis we compute the water intensities for domestic production and imported products of 90 product groups and connect them with household expenditures described for 2899 Czech households. In our analysis we use data for 2018 and describe the results separately for blue and green water footprint. The mean annual consumption of blue and green water is 214.3 m3 and 2544 m3 respectively per household member. The highest responsible category for total water footprint is category of food with the 74 %. This category has also the largest computed water intensity among the twelve consumption groups. Analysis also showed the water footprint is distributed unevenly through the households divided to deciles by expenditures. The lowest decile uses about 4 % of total water footprint in comparison to tenth decile consuming almost 18 %. By the linear regression of expenditures and water footprints we got the statistically significant elasticities varies between 0.48 to 2.71. Keywords Water...

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...

Water footprint of crops for biofuel production
Straka, Štěpán ; Hrkal, Zbyněk (advisor) ; Rozman, David (referee)
The aim of the bachelor's thesis is to apply a research study for the assessment of often- overlooked effects of growing crops used for the production of biofuels, according to their so- called water footprint. In the theoretical part, the thesis focuses on the definition of the concept of the water footprint, its history and the gradual development of people understanding the impact. Furthermore, the thesis deals with the issue of definitions and determination of water scarcity. The theoretical part concludes with basic information about biofuels, their division and a presentation of the most commonly used biofuels. The following chapters summarize the current state of biofuel production in the world and familiarize the reader with the issues this production causes. The main part of the thesis is the synthesis and processing of data regarding the water footprint of selected crops grown as a source of biofuels, comparison of the values with climate zones and evaluation of the suitability of the production of these crops concerning water resources. Keywords: water footprint, biofuels, maize, canola, sugarcane, oil palm
