Humulus lupulus L. is a long-lived, perennial, herbaceous, and dioecious climbing plant. The foremost producers in the European Union are Germany, the Czech Republic, Poland, Slovenia, and Spain. The Spanish cultivated area is concentrated in the province of León. Powdery mildew, caused by Podosphaera macularis, menaces hop production and quality in all hop growing regions located in the Northern hemisphere, colonizing leaves, petioles, inflorescences, and finally cones. In this work, powdery mildew control was monitored, comparing nine fungicide strategies: five organics, two integrated disease management (IDM)-based, with and without Nutragreen® nanoscale carrier, and two conventional treatments (CON) with and without Nutragreen® nanoscale carrier. The organic treatments were able to diminish P. macularis on leaves, but no effect was observed in cones. CON treatments reduced the infection on leaves and cones and increased the cone quantity and quality. Likewise, IDM-based treatments provided satisfactory results as they diminished powdery mildew on leaves and cones. Finally, dose reduction using a Nutragreen® nanoscale carrier showed beneficial effects in the control of powdery mildew compared to the commercial dose. Hence, the use of nanoscale carries permits a 30% reduction in pesticide dose, which optimizes yield and hop quality, reduces risks linked to pesticides, and aids in compliance with public and international policy demands.

This article compares attitudes to buying organic food in selected countries in Central Europe. The current research was conducted in 2019 on a total sample of 2800 respondents in the Czech Republic, Slovakia (Central Europe, with a relatively new organic food market), and Germany (a traditional Western Europe country with a mature food market). The study results demonstrate significant differences between the three selected markets. The product quality is the most important for German consumers. Slovak consumers consider organic food to be the least recognizable and least promoted of all the regions surveyed, and they are also the least likely to encounter targeted advertising for organic products. Germany is the country where most respondents regularly or occasionally buy organic food. In Slovakia, an interesting finding is the highest proportion of respondents who do not buy organic food at all. Czech respondents often buy organic products in specialized shops and like to grow organic products themselves. The results also suggest that Slovak consumers slightly more often prefer foreign organic products to the local ones, whereas consumers in Germany select regional organic products more often and prefer to buy regional products at farmers’ markets.

Sufficient supply of woodworking with raw materials while preserving the ecology and rational use of wood is a necessary condition for the functioning of the woodworking industry as one of the key segments of the national economy. The issue is of particular importance given the deepening of world integration processes and the introduction of a moratorium on timber exports from Ukraine. It actualizes the study of the state and dynamics of the formation of raw materials potential of domestic woodworks. The purpose of the article is a structural and dynamic assessment of the economic and environmental aspects of formation of the resource potential of Ukrainian woodworks in comparison with the countries of the European Union, as well as in the regional section by types of wood. In the structure of merchantable wood harvested in Ukraine, fuel wood share increased by 4.3 pp. during 2011-2016, whereas in 2017 it increased by 3.8 pp. compared to 2016 and amounted to 61.4%. Unlike in Ukraine, in the vast majority of EU countries business timber is the basis of the structure of harvested merchantable timber. Thus, in the neighboring countries with similar forest landscape – Poland and the Czech Republic – the share of fuel wood in 2017 was 11.6% and 12.3%, in Slovakia – only 6.3%, and in the EU as a whole – 23. 2%. Hence, the significant deterioration of the structure of the harvested merchantable timber in Ukraine can be interpreted as a threat to environmental, and therefore to national security. On the other hand, the results of the assessments revealed an increase in the volume of commercial timber harvesting in Ukraine (in 18 regions) in 2018, as well as in the level of forest reproduction in the leading regions from the harvesting of merchantable timber (Zhytomyr, Kyiv and Rivne regions) and a decrease in the death rate. The restoration of the logical patterns between the dynamics of the loss of stands and the harvesting of commercial and fuel wood are signs of the beginning of positive tendencies in ensuring the preservation and rationalization of raw potential of domestic woodworks and, at the same time, improving the conditions for deepening the level of wood processing. Further authors’ research in this area will be devoted to the search for effective forms of wood industry development in Ukraine, in particular in the Western region.

This chapter focuses on defence transformations in the Czech Republic, Slovakia, and Hungary since the end of the cold war. The three lesser powers of Central Europe all eventually joined NATO and the European Union, following the fall of the Iron Curtain. The process they underwent completely transformed their security strategies and military doctrines, but the plans to transform their military forces have developed slowly, and the actual process has been interrupted and incomplete. This chapter addresses the development of civil–military relations, the main milestones in the development of the respective states’ national security policies, and the main changes in the structure of military forces in each of these countries. Finally, the chapter looks at the nascent trends towards military cooperation between the three countries, including military sharing and joint procurement.

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.

In between the writing of this editorial and the publication of this issue of EuConst, the Treaty on Stability, Coordination and Governance in the Economic and Monetary Union, in everyday parlance the ‘Fiscal Compact’, will have been signed by the representatives of the governments of the contracting parties — the member states of the European Union minus the United Kingdom and the Czech Republic. The Fiscal Compact is intended to foster budgetary discipline, to strengthen the coordination of economic policies and to improve the governance of the euro area.

One of the key markets of the European Union is the poultry meat market. The situation on this market is of significant importance to both producers and consumers. The main aim of the article is to study the level of self-sufficiency of selected countries in Central and Eastern Europe in the production of poultry meat. Eleven countries were selected as the research area: Bulgaria, Croatia, the Czech Republic, Estonia, Lithuania, Latvia, Poland, Romania, Slovakia, Slovenia and Hungary. In the conducted research, simplified indices of self-sufficiency were used: the balance of foreign trade in terms of volume and value, average annual consumption per capita and production volume in relation to consumption. The study was conducted for the years 2009-2018. The statistical sources used come from FAOSTAT and International Trade Centre databases. Research has shown that the analyzed countries are characterized by a significant diversification of the self-sufficiency level of poultry meat production. Only 6 analyzed countries can meet the domestic consumption demand from their own production, the remaining countries supplement the deficit from imported goods. The highest level of self-sufficiency of poultry meat production was observed in Poland, Slovenia, Lithuania and Hungary. On the other hand, the lowest level is found in Bulgaria, the Czech Republic, Estonia, Slovakia and Latvia.
