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.

AbstractClimate change affects the distribution of many species, including Burgundy and Périgord truffles in central and southern Europe, respectively. The cultivation potential of these high-prized cash crops under future warming, however, remains highly uncertain. Here we perform a literature review to define the ecological requirements for the growth of both truffle species. This information is used to develop niche models, and to estimate their cultivation potential in the Czech Republic under current (2020) and future (2050) climate conditions. The Burgundy truffle is already highly suitable for cultivation on ~ 14% of agricultural land in the Czech Republic (8486 km2), whereas only ~ 8% of the warmest part of southern Moravia are currently characterised by a low suitability for Périgord truffles (6418 km2). Though rising temperatures under RCP8.5 will reduce the highly suitable cultivation areas by 7%, the 250 km2 (3%) expansion under low-emission scenarios will stimulate Burgundy truffles to benefit from future warming. Doubling the moderate and expanding the highly suitable land by 352 km2 in 2050, the overall cultivation potential for Périgord truffles will rise substantially. Our findings suggest that Burgundy and Périgord truffles could become important high-value crops for many regions in central Europe with alkaline soils. Although associated with uncertainty, long-term investments in truffle cultivation could generate a wide range of ecological and economic benefits.

Utilization Of Wastes

The value of consumption share of electricity from renewable sources in the Czech Republic up to 8% in 2010 stems from an individual obligation adopted by the Czech Republic when signing the Kyoto Protocol of the United Nations Framework Convention on Climate Change. One of the possibilities how to reduce greenhouse gases emissions from fossil fuels consists in biomass burning. Biomass used for power purposes is obtained on purpose as a result of production activities or it originates from utilization of wastes from agricultural, forest and industrial production. In biomass burning, the boiler used produces carbon dioxide, recyclable in nature. Increase of the amount of municipal and technological waste including materials that are heavily soiled and difficult to recycle pushed up demand to obtain the best possible solutions in terms of both technological and economic terms. Recycling of materials can provide multiple circulations which have to lead to final solution such as storage or use in energy production. One of the solutions shall consist in recommending the installation of the sorting line, the homogenizer, and possibly a pelletizer to ensure sufficient homogeneity of the material.

Invasive non-native insect species are well-known threat to both local and introduced plant species in Europe. With increasing global trade and effects of climate change it is expected these alien species will continue to expand their distribution areas. One such non-native species is azalea sawfly Nematus lipovskyi Smith, 1974 (Hymenoptera: Tenthredinidae) that feeds on deciduous Rhododendron spp. This species is known to occur in the USA and was found in the Czech Republic for the first time in Europe in 2010. We report the first findings of this species in Latvia that were made based of field observations in the period of 2018-2020. The current known status of the species in Latvia is presented. Our observations of damage caused by sawfly larvae are summarized. Host plants used by sawfly larvae are listed – we note Rhododendron albrechtii as a host plant of this species for the first time. The possible pathways of its introduction and the overall importance of our findings in context with other non-native species expansions are briefly discussed.
