Research background: Water is a scarce natural resource essential for life and also many economic activities. Scarcity of drinking water is a problem that is ad-dressed at national and international levels. Global water demand continues to rise, but the quantity and quality of water resources is declining in many regions. Recent surveys of the population of the Czech Republic show that the most serious global problems are waste accumulation, water pollution, lack of drinking water and air pollution. Average temperatures continue to rise across Europe due to climate change and water is expected to become increasingly scarce in many areas. An adequate supply of good-quality water is a pre-requisite for economic and social development, and thus it is necessary to learn to save water and better manage our available resources in this area. Purpose of the article: The purpose of this study was to investigate to what degree environmental problems — especially the issue of drinking water scarcity — have been evaluated in the Czech Republic from 2014 to 2018 and whether the fear of a lack of drinking water has motivated water conservation. Methods: A regional analysis of water availability in the Czech Republic and the possible causes of water scarcity has been carried out. Subsequently, selected socio-economic factors that could have an impact on the assessment of drinking water scarcity are analyzed using Gamma and Kendall's Tau and logistic regression. The analyzed time period is from 2014 to 2018. Microdata was taken from the Centre for Research of Public Opinion, and selected regional-level statistics from the Czech Statistical Office have been added to this data to supplement it. Findings & Value added: The perception of drinking water shortages is not only influenced by indicators representing the volume and price of water in each region, but can also be determined by other socio-economic factors such as income, gender, age and education.

This article deals with the phenomenon of invalid voting which has appeared in regional elections in the Olomouc region in the Czech Republic. First, contemporary theories of invalid voting are introduced. Second, the given hypotheses, which include both institutional and socio-economic factors that, according to the theories, contribute to higher levels of invalid voting, are tested. Statistical analysis such as linear regression is employed in the research. The dataset is comprised of municipalities (cases) in which regional elections were held. The results show that higher levels of invalid voting are associated with concurrent elections (elections to the regional assembly and elections to the upper house (the Senate) of the Czech Parliament) in those municipalities in which residents are older and less well-educated. If regional elections are held without concurring elections, socio-economic variables have a smaller effect on invalid voting. Therefore, the state authorities should consider a revision of respective electoral law and simplify the electoral process involved in concurrent elections.

Abstract Health inequalities, which could be prevented by appropriate means in various areas, are generally perceived as a consequence of injustice in the society and are mostly the result of inequalities in social determinants. The main goal of this article is to determine health inequalities defined by demographic and socio-economic factors at the level of districts of the Czech Republic in the period 2007–2018(due to the specific differences in data, the Capital City of Prague region was not included). The following statistical methods were used to process the data: correlation analysis, principal component analysis, composite indicator, cluster analysis and multidimensional factor analysis. The value of the composite indicator shows a very favorable situation in the districts of Praha-východ and Praha-západ (especially high proportion of university students, low unemployment, age index, infant mortality, abortion rate and housing subsidies), and the unfavourable situation in the districts of Chomutov, Teplice and Most (especially high housing and unemployment subsidies, low rate of university students, negative migration balance, high rates of infant mortality and abortion). The results specify regional disparities of demographic and socio-economic indicators that can cause health inequalities: negative regional disparities (Most, Teplice, Děčín, Bruntál, Karviná, Ostrava-město and Jeseník districts) and positive regional disparities (Praha-západ, Praha-východ, Mladá Boleslav, Jihlava and Brno-venkov). The study presents the results of analyses based on the example of smaller territorial units (districts) and confirms the existence of regional disparities in accordance with research at the national and international level. Highlights for public administration, management and planning: • Demographic factors are connected to socio-economic environmental factors (poverty, education, social exclusion, unemployment, social security, family situation etc.) that lead to regional health inequalities. • The regional disparities of selected demographic and socio-economic indicators of the districts of the Czech Republic that cause health inequalities were specified.

The paper is focused on assessing the development of the economic account for agriculture of the Czech Republic in the selected reference period 1998–2003. There were evaluated effects of the particular types of the economic accounts. Methods of regression and correlation analysis and development trends were used for the mathematical-statistical analysis. The plant production output similarly as the output of agricultural industry show an increasing tendency since the period under investigation reaching a peak about 2001 and in next years decreasing in difference to the gross value added at basic prices and the net value added at basic prices which shows an increasing trend throughout the period. Both animal output and the agricultural services output show a decreasing trend reaching a minimum about 2002.

In the European Union, soil erosion is identified as one of the main environmental threats, addressed with a variety of rules and regulations for soil and water conservation. The by far most often officially used tool to determine soil erosion is the Universal Soil Loss Equation (USLE) and its regional adaptions. The aim of this study is to use three different regional USLE-based approaches in three different test catchments in the Czech Republic, Germany, and Austria to determine differences in model results and compare these with the revised USLE-base European soil erosion map. The different regional model adaptations and implementation techniques result in substantial differences in test catchment specific mean erosion (up to 75% difference). Much more pronounced differences were modelled for individual fields. The comparison of the region-specific USLE approaches with the revised USLE-base European erosion map underlines the problems and limitations of harmonization procedures. The EU map limits the range of modelled erosion and overall shows a substantially lower mean erosion compared to all region-specific approaches. In general, the results indicate that even if many EU countries use USLE technology as basis for soil conservation planning, a truly consistent method does not exist, and more efforts are needed to homogenize the different methods without losing the USLE-specific knowledge developed in the different regions over the last decades.

The aim of this paper is factors identification of the decreasing natality trend in the Czech Republic between years 1991–2005. This identification is done with respect to the financial situation and living standard of families.The first step, analysis of natality factor – animation natality, is performed. Animation natality is divi­ded according to the mother family state in the time of the birth. Trend of born in marriage and trend out of marriage are described. Following analysis is focused on decreasing component of natality – number of born in marriage.The second step is time series correlation analysis used for identification and evaluation influence of demographic and economic factors on decreasing component of natality. Based on this analysis, in­fluen­cing factors for regression model describing natality are selected.The last step is formulation and estimation of multiple regression model describing causality between natality in marriage and selected factors.

Abstract Historical maps are a valuable resource in landscape research. The information gathered from them facilitates the cognisance of landscapes and may assist current landscape planning. This study focuses on the historical occurrence and spatial extent of man-made ponds in the Czech Republic. Based on the 1st Military Survey maps (1764–1783) of the Habsburg Monarchy, we use Historical GIS to identify 7,676 man-made ponds in the historical landscape. Compared to the 2nd Military Survey maps (1836–1852), 56% of these man-made ponds had been drained. Such disappearances mostly affected large ponds in fertile agricultural areas, but also affected small reservoirs in less fertile areas at higher altitudes. As the current maps and spatial datasets (Water reservoirs, Landscape water regime, Farming areas) show, a number of these agricultural regions have been affected by climate changes and face water shortages. The historical map information of former ponds has the potential to contribute to their restoration in areas where water retention in the landscape needs to be increased.

Abstract Combined mixing and aeration systems are not given priority in the Czech Republic. Still, they are installed at several WWTPs. Their advantage is mixing and aerating at the same time. This article provides data from actual measurements where a combined system was used for drinking water including necessary chemicals. The text below evaluates the course of changes in the concentration of dissolved oxygen in different points in the reactor depending on time.

Restructuring Process

The decreased demand for new vehicles will put pressure on the economy of the Czech Republic, a country deeply integrated into global value chains, as part of global vehicle production. The aim of this research was to define an appropriate industrial policy for the Czech Republic that will ensure that the country maintains its competitive position in the global market. A constrained optimization model was built, based on input–output analysis, to determine the optimal value-added structure and the intersectoral structure of the Czech economy for the country to retain its exporting character. The optimization problem was solved by using a particle swarm optimization algorithm. The results suggest that the optimal industrial policy plan for the country is the structural transformation of production, mainly targeting the development of technologically advanced sectors of manufacturing (such as: chemicals and chemical products; basic pharmaceutical products; computer, electronic, and optical products; electrical equipment; and machinery and equipment). The suggested restructuring process increased the domestic value-added in gross exports as a share of total exports by 6.77%, creating optimal production capabilities for the economy. The Czech Republic appears to have the potential for the implementation of an industrial policy, avoiding the increasingly vulnerable motor-vehicle sector.
