Abstract The landscape of the Czech Republic currently faces droughts that are caused by several factors. One of the reasons for drought is landscape development and land cover changes. Changes in water and wetland areas and streams were studied by comparing old military maps and the present state. Water and wetland areas in fertile lowlands significantly decreased over time; the landscape was continuously dried out with the aim of increasing agricultural and woody production. While water and wetland areas occupied nearly one-third of the study area (Nové Dvory and Žehušice micro-regions in Central Bohemia) at the end of the 18th century, the present share of these areas is only 3.5%. There was a decrease of approximately 10% in each period, and nearly all of these areas disappeared by the end of the 19th century. Water and wetland areas were changed primarily to arable land. The length of streams decreased by the end of the 19th century. Drainage and irrigation channels were built during the 20th century, and although they are only periodic or episodic streams, these channels increased the total length of streams.

Abstract The aim of the paper is to evaluate the effects of loose monetary policy on corporate investment of manufacturing firms in the Czech Republic during the period between 2006 and 2015. The main focus of the paper is on the effect of low interest rates on investment activity of Czech firms; additionally, the effects of interactions between interest rate and other firm-specific variables are investigated. The results indicate that corporate investment is positively associated with firm size, investment opportunities, and long term debt. Also, a negative effect of the cash position is found. Further, the findings show that monetary policy is a significant determinant of firm investment activity: when the monetary policy is loose, investment is positively affected. Furthermore, differences in the determinants of investment between highly and low leveraged firms were revealed.

Abstract The processing of ombrographic data from 29 meteorological stations of the Czech Hydrometeorological Institute (CHMI), according to the terms of the Universal Soil Loss Equation for calculating long term loss of soil through water erosion, erosion hazard rains and their occurrence have been selected, with their relative amount and erosiveness - R-Factors determined for each month and years. By comparing the value of the time division of the R-Factor in the area of the Czech Republic and in selected areas of the USA it has been demonstrated that this division may be applied in the conditions of the Czech Republic. For the Czech Republic it is recommended to use the average value R = 40 based on the original evaluation.

This article essentially covers in more detail the consequences of the present wording of the Public Contract Law for purchase of scientific appliances in the Czech Republic. The beginning of the article deals with increasing public expenses in research; then, the problem is defined concerning unsuitable wording of certain provisions of the Public Contract Law; while subsequently, the solution for the problem is searched together with the final comments. Investing of public funds into science and research is probably the most efficient in a long-term horizon. However, the flow of funds for acquisition of scientific and research equipment should be supported by appropriate legislation with such wording and form not to prevent purchases of that equipment. Availability of public funds for something which in fact cannot be, due to wrongly set legislation, acquired by a contracting authority is the problem which must be eliminated through timely implementation of the above proposed changes in the Public Contract Law.
