Abstract Subsurface drainage systems are very important type of meliorative measures in the Czech Republic. Nevertheless, their functions are perceived differently in the Czech society. We can distinguish point of view of landowner, farmer, water manager or environmentalist. With regard to the climatic changes or new praxis of agricultural, there must be assessed changed conditions in relation to existing drainage systems. It has connection with the next strategy of their funding and management. Therein, in the Czech Republic, farmer has dominating position, instead of the state or landowner that would be probably more correct.The paper presents results of user demands survey, conditions of drainage systems, their services and defects. New technologies, mainly remote sensing, and their use for identification and survey of drainage systems are presented too. Land drainage measures changed the whole landscape in the Czech Republic (agricultural intensification, loss of natural habitats and natural water flows etc.). In context of hydrological extremes′ rising and drainage systems′ ageing, existence of drainage systems must be solved. It means their maintainance for purpose of agricultural production, or, on the contrary, their elimination with the view of nature habitats′ recovery. Both solutions must differ in accordance with the different landscape characteristics of the Czech Republic.

Active Substances

The present paper compares the production of active substances in different subspecies of Achillea millefolium complex growing in the Czech Republic. Representatives of 7 subspecies of A. millefolium complex (A. setacea Waldst. et Kit., A. asplenifolia Vent., A. pratensis Saukel et Langer, A. collina Rchb., A. styriaca Saukel et Langer subsp. bohemica, A. millefolium subsp. millefolium, A. pannonica Scheele) and several natural hybrids of Achillea L. were collected from 75 natural habitats in different parts of the Czech Republic. Plants were cultivated to investigate plant growth and contents of some effective compounds during 1997–1999. Development of plants was divided into 7 typical phenological phases. From the point of view of active substance production, the stage of early flowering was found as the most suitable phase for Achillea (yarrow) harvest. Air-dried powdered flowering heads were analysed for essential oil, tannin and flavonoid content. The essential oil content was obtained by hydro-distillation; the composition of essential oil was analysed by means of gas-liquid chromatography. The total essential oil content of the examined yarrow species ranged between 0.05% and 0.88% of dry matter; ecotypes of A. collina and some of its hybrids showed the best results with the highest content of deep blue essential oil. Content of tannins was determined according to PhBs IV; flavonoids were expressed as an apigenin content by an internal method of pharmaceutical company IVAX ČR, a. s., Opava. The total flavonoid content was in the range of 1.37–3.97%; the content of tannins ranged from 0.02 to 0.64%. The highest content of flavonoids was determined in the sample of A. styriaca subsp. bohemica (3.97%); the highest content of tannins was found in an A. asplenifolia sample (0.64%).

The Impact

Global and regional biodiversity loss is caused by several drivers including urban development, land use intensification, overexploitation of natural resources, environmental pollution, and climate change. The main aim of our study was to adapt the GLOBIO3 model to the conditions of the Czech Republic (CR) to assess loss of naturalness and biodiversity vulnerability at the habitat level on a detailed scale across the entire CR. An additional aim was to assess the main drivers affecting the biodiversity of habitat types. The GLOBIO3 model was adapted to CZ-GLOBIO by adapting global to local scales and using habitat quality and naturalness data instead of species occurrence data. The total mean species abundance (MSA) index of habitat quality, calculated from the spatial overlay of the four MSA indicators by our new equation, reached the value 0.62. The total value of MSA for natural and near-natural habitats was found to be affected mainly by infrastructure development and fragmentation. Simultaneously, intensity of land use change and atmospheric nitrogen deposition contributed primarily to the low total value of MSA for distant natural habitats. The CZ-GLOBIO model can be an important tool in political decision making to reduce the impact of the main drivers on habitat biodiversity in the CR.

The Individual

This assessment of societal readiness and resilience to water-related situations in the Czech Republic focuses on an interdisciplinary approach in the Czech Republic for solving this problem. The goal of the article is to evaluate and characterize the preparedness for handling water-related crises. The analysis is carried out via a SWOT analysis, which is a universal analytical method used to understand and interpret strengths and weaknesses and to identify opportunities and threats. For the calculation of the weight factor of the SWOT analysis, an assessment was determined based on the multicriteria analysis. The pair comparison method was used to determine the relative importance of the parameters of the strengths and weaknesses, opportunities and threats. The Fuller Triangle method was chosen for the system used to make the comparisons of the individual criteria. The uniqueness of the study consists of the issue of water management, which is thus reflected from a non-traditional perspective, being a contemporary model—the paradigm of the view on the preparedness of the planning documentation as one of the characteristics of societal resilience for water-related crises. The result of the research is the fact that a positive approach prevails in the researched area from the perspective of preparedness for water-related crises. For the creation of the conditions, the factors arising from the internal environment currently prevail slightly over those arising from the external environment.

This paper aims to introduce the current trends in anti-Semitism in the Czech Republic in 2004-2014. This period maps the changes that appeared since the end of Second Palestinian intifada to the year 2014 which is the last year with available set of data of anti-Semitism in Czech society. The article shall examine whether there is a direct link between the contemporary important events in the Middle East and the changing number of anti-Semitic incidents in the Czech Republic. The attention shall also be given to the issue which groups of Czech society are mostly associated with anti-Semitism and what is their main motivation to participate in the anti-Semitic campaign.

The contribution “Anti-state Crimes in Modern Codifications” deals with the topic of anti-state crimes during centuries. Firstly, legal concepts in the pre-state period are mentioned. Then the attention is paid on the evolution of this institute in the Euro-Atlantic area. From this point of view, there are mentioned mainly regulations from England (1351), France (1810), Germany (1871) and Soviet Union (1958) which could be remarked as the most important for the development of other countries. On the other hand, it also reminds the development of codifications in Czechoslovakia, the Czech Republic and Slovakia, which were affected by the Austro-Hungarian legislations as well as German and Soviet approaches. The Czech current arrangement generally does not depart from the other European samples, but it cannot be omitted that in the Czech Republic it is distinguished the penal concept of the high treason (Landesverrat, vlastizrada) from the constitutional concept (Hochverrat, velezrada) which is dedicated to the presidential anti-state activities. The contribution also indicates that the concept of anti-state crimes in countries has not been unified and it has been varying according to various experiences and attitudes.
