The aim of the presented article is to evaluate the impact of climate change on the sugar content of grapes in the Czech Republic during the period 2000–2019 through selected indicators on the basis of available secondary sources. Attention is focused on the developments in both the main wine-growing regions of Moravia and Bohemia. In the field of viticulture and wine-growing, the sugar content of grapes, as a basic parameter for the classification of wines, plays an important role. In the Czech Republic, the average sugar content of grapes has had a constantly growing trend. This trend is evident both in the wine-growing region of Bohemia and in the wine-growing region of Moravia. The impact of climate change, especially the gradual increase of average temperatures in the growing season, cannot be overlooked. It greatly affects, among other things, the sugar content of grapes. Calculations according to the Huglin Index and the Winkler Index were used to determine the relationship between climate and sugar content. These indexes summarize the course of temperatures during the entire vegetation period into a single numerical value. The results show that both indexes describe the effect of air temperature on sugar content in both wine regions of the Czech Republic in a statistically significant way. The Huglin Index shows a higher correlation rate. The Winkler Index proved to be less suitable for both areas. Alternatively, the Winkler Index calculated for a shorter growing season was tested, which showed a higher degree of correlation with sugar content, approaching the significance of the Huglin Index.

The Impact

Abstract The paper’s aim is to examine the dependence of the quality of the business environment on defined technological factors (availability of human capital and research and development infrastructure) and to define and quantify significant technological factors that create the quality of the business environment in the SMEs segment. Part of its goal was the comparison of the defined factors between the Czech Republic (CR) and the Slovak Republic (SR). In connection with the stated research goal, a questionnaire survey was conducted among businesses operating in the SME segment. Through this research, 312 companies were surveyed in the Czech Republic and 329 companies in the Slovak Republic. To achieve the primary goal of the article, methods such as correlation analysis and multiple linear regression modelling (t-tests, F-ratio, adjusted coefficient of determination, and so on) were applied. The results of the research have brought interesting findings. Research and development infrastructure, as well as the availability of human capital are important factors that have a positive impact on the business environment in both countries.

Case Basis

A number of possible relationships between climate change and water quality of Dutch surface waters have been investigated and an indicative quantification of the impact of climate change on water quality has been established. The analysis focused on water quality during periods of low flow and extreme heat, which are assumed to increase in frequency and intensity due to climate change. The results indicate that the impact of climate change on water quality cannot be generalised and should be assessed on a case by case basis. However, the impact on extreme situations (floods and droughts) seems to be largest, whilst water quality under average discharge conditions appears to be relatively unchanged.

Chlorosis Resistance

Resistance to lime-induced chlorosis is very important characteristic of grapevine rootstocks. Lime-induced chlorosis influence yield and quality of grapes. Evaluation of chlorosis resistance is very important for grape growing and breeding. The aim of this work is provide results of evaluation grapevine rootstocks to chlorosis. High resistance was show in Fercal. From the viewpoint of the resistance to chlorosis, the rootstocks registered in the State Variety Book of the Czech Republic can be ranked from the most resistant to the most sensitive as follows: Craciunel 2 – SO 4 – Kober 125 AA – Kober 5 BB – Teleki 5 C – Amos – LE-K-1.

Abstract Does climate change affect the quantity and quality of the wells near the artificial recharge site? Considering the research background, it seems that there has not been a comprehensive study on the impact of climate change and the trend of groundwater quality changes in jafakendeh aquifer. In this study, relation jafakendeh aquifer, climate change in north Iran, evaluated. Therefore, the purpose of this study is to examine trends, changes in groundwater level with some climatic variables of jafakendeh aquifer with the non-parametric Mann-Kendall method and Change-Point Detection with Pettitt’s process. The results of the model show that the climate change factor does not affect the groundwater level after the establishment of an artificial recharge system. The results of the research can be used for evaluation Cost-Benefit Analysis of artificial recharge sites after construction.
