In the European Green Deal and the Climate Act, the European Union has committed itself to achieving climate neutrality by 2050. This goal is to be achieved by joint efforts of all economic sectors, including forestry and its downstream sectors. One way to attain this goal is the effective and sustainable use of forest biomass for energy production. This article aims to quantify the potential of forest biomass resources for the production of electrical and thermal energy based on official departmental statistics, the current legal framework for forestry and the environment, and research results in the context of an extreme change in the raw material base due to the ongoing calamity caused by the spread of insect pests in the Czech Republic. This extreme can classify as a significant risk to the security of the energy supply from renewable sources in the event of oversizing new installed energy production from renewable sources. Based on data and calculations, an overall annual volume of dendromass available for energy production in the Czech Republic for the period extending to 2036 was quantified at the value of 13.473 million tons per year. Consequently, it is clear that the overall dendromass resources for energy production in the Czech Republic are not sufficient to achieve the EU’s ambitious objective.

The current requirements put on the Member States of the European Union (“EU”) in the area of sustainability and climate-neutral economy through strategic visions such as “Agenda 2030” or “A Clean planet for all” demonstrate the increasing need for quick identification of the changes required in the use of renewable and nonrenewable natural resources. Forests are a particular specific area of such changes. They represent a part of the ecosystem that is important for society from the economic, social, and environmental perspectives. Current climate changes have had a negative effect on the state of forestry in the Czech Republic and have raised many questions of how to ensure its sustainability. Besides the changes in forestry, the situation has also affected the sector primarily depending on the production function of forests and whose coexistence is conditioned. Taking specific sectors as examples, the article presents some prospects that could result in more efficient use of resources and defines potential synergic effects. Analyses of primary and secondary information sources were used to create preferential models (the term “preferential” in the context of the article represents opportunities through which it is possible to achieve an improvement in competitiveness and market advantage over the current model of wood processing and timber trade in the Czech Republic. The model works with potential perspectives and respects the challenges in the field of sustainable development) of timber and wood raw material production and processing and preferential and of economic efficiency (the term “efficiency” in the article represents the technical efficiency of the use of resources to achieve maximum economic benefit and added value. The aim is to increase the economic potential of individual sectors of primary and secondary processing in relation to timber sources) of woodworking businesses. The production model indicates that the energy use of wood, the expansion of the production mix in construction, the use of biomass and digestate in agroforestry, and the logging waste recovery are the most prospective sectors. The model presenting preferential areas in the woodworking industry development with respect to sustainability identified the need to increase associated production and material efficiency in construction and energy sectors, as well as insufficient activity of the sectors associated with technological innovations, FSC and PEFC certification prospects, bioeconomy and circular economy, a considerable need for wage growth in the sector and increased use of the existing production capacities by both domestic and foreign sales.

Sulfur binders belong to the group of airbrushes. They can therefore only harden and harden in the air. The main raw material, gypsum, can be mined in several places in the world. Even in the Czech Republic there is a deposit of natural gypsum in Kobeřice u Opavy. [5] In spite of this fact, we use mostly industrially produced gypsies, because the natural gypsum deposit has only very limited capacity. The Energogypsum, produced in the Czech Republic by ČEZ Energetické Produkty s.r.o., is the waste product of flue gas desulphurization using the wet limestone scrubbing method. Like the chemosynthesis, it is characterized by its high purity (the content of pure CaSO4 2 H2O is at least 90%). The one in the Czech Republic is manufactured by Precheza, a.s. in Přerov. The use of sulphate binders is varied. A better form in the form of alpha plaster is used to produce self-leveling floors and dentistry. Less-quality beta gypsum has a larger application. From it we can produce both gypsum and monolithic partitions. We can also use it for the production of plasterboard and gypsum fiber boards and, last but not least, as internal plasters for its good fire performance. [1] Plasters are being prepared today in two different ways. Firstly, they are still prepared in the original outpatient way directly on the building from individual raw materials, but they are also industrially produced in the form of dry mortar mixtures, which are mixed on the building only with water. The second way is more progressive with the fact that nowadays it is even more widespread. For many builders, however, it remains financially scarce. That is why we have recently begun to find a compromise solution that will satisfy both the technical and the economic ones. This is the development of the so-called binder premixes, ie the industrially produced mixed binder, which is mixed only with sand and water on the site. The situation on our market shows that the recently developed special premix for lime-cement plaster and mortar mixtures is very positive for the building public and therefore the effort is to generalize this mixed mortar in the production raw material base and, in addition, to develop its analogue based on sulphate binder.

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.
