Increasing recognition and importance is being given to regions for their role in supporting Europe’s transformation towards a sustainable and circular bioeconomy system. Regions are often feedstock producers and can provide the proximity of regional actors along the value chain. If supported and mobilized, actors can coordinate strategic paths for regional bioeconomy development and keep value added in the region. Regional bioeconomy strategies are an important instrument to reach such a process, which implies great efforts of coordination among relevant stakeholders. In this research, we developed a guideline to establish flexible dynamic bioeconomy platforms—Regional Bioeconomy Hubs (RBHs)—that bring together bioeconomy-related stakeholders from policy, academia, industry, and society in a structured procedure (quadruple-helix context) and to establish regional bioeconomy strategies. The guideline was applied to five Central and Eastern European regions and validated in the framework of the POWER4BIO project. As a result, all regions successfully applied the guideline, established their RBH, and developed a regional bioeconomy strategy or recommendations for the development of such a strategy.

Renewable energy is the key pillar and plays an important role in the energy systems of European Union member states and in mitigating climate change. It is supporting the transition towards a greener, resource-efficient and more competitive, low-carbon European Union economy. Above-average, average and below-average values of monitored indicators in member states of the European Union in 2009–2016 were ascertained by using principal component analysis. Monitored indicators of the renewable energy sector included electricity generation, electricity capacity, investments of public financial institutions, number of employees and turnover achieved from the economic activities related to production, distribution, installation, operation and maintenance of equipment (all of them per capita). Based on the achieved results, we can state that the situation changed during the period under review. Member states have moved between above-average, average and below-average levels of renewable energy indicators. However, a lack of change in the indicators was recorded in some member states throughout the eight-year period (Finland, France, Ireland, Germany, Austria and Spain did not move significantly). Renewable energy sources (hydro, wind, solar, geothermal and energy from biomass) were evaluated as a whole due to different natural, economic and legislative conditions of European Union countries.

This paper offers a case study of three selected ecovillages (two in Hungary and one in Slovakia). The main objective is to characterize, analyse and eventually compare types, trends and problems in the development of ecovillages and to discuss the possible impacts and effects of ecovillage movement on sustainable rural development. The authors used interviews, observation and inquiry for data collection and methods of document analysis, content analysis of different sources, and analysis of foot marks. They attempt to bring the worldview closer by introducing the basic ecovillage concept and framework, and by describing the ecovillage types, recent trends, problems and challenges. The analytical part begins with a short characteristic of the ecovillage movement in Hungary and Slovakia and follows with six thematic subchapters that investigate and compare the observed ecovillages according to the purposes and motivation for their founding, the communication models and public relations, local economic systems and self-sufficiency phenomenon, the employment structure and the existing infrastructure. Finally, the last part is devoted to assess the main research findings.

The current economy transcends the boundaries of sustainability, threatens the quality of life on Earth and, ultimately, of the man himself, which requires its restructuring to a sustainable one. The unsustainability of the development of society, which causes the development of the economy in a global environment, is revealed by theoretical research based on qualitative analysis of texts and documents. Subsequently, the need to change the paradigmatic basis of economic theory is explained and a new model of economy – sustainable economy – is outlined. Using logical methods and comparison of basic axioms, postulates and based on the prediction of further development, the study emphasizes that moving towards a more sustainable future presupposes the replacement of neoclassical paradigm by a new paradigm – the paradigm of sustainable development. Restructuring the economy into a sustainable one will be based on this paradigm, as confirmed by some of the outlined new economic theories and initiatives.

Sustainability and innovation are key elements of the economic growth and productivity in the contemporary era. The willingness, ability, and capacity to innovate is a strategic tool for the Slovak agro-food companies that want to maintain and/or to improve their market. The aim of this paper is to discuss the selected aspects and determinants of innovative performance of the Slovak agro-food companies and point out key areas and types in innovations, problems influencing their implementation, and assessing their success. The issue of innovation and the “new” role of the agro-food sector have become crucial in the context of transition of the Slovak economy toward more sustainable approaches. Therefore they have become important topics of both scientific research and policy agendas. Using a case study method, a questionnaire survey among 99 agro-food companies in Slovakia was carried out to obtain empirical data about the way how they manage, implement and evaluate the innovations. The study outlined the selected aspects and key determinants which affect the motivation of agro-food companies to innovate as well as selected factors influencing the processes of implementation and management of innovation. The research findings also point out that substantial changes will be required in regulation and support of innovations in the agro-food sector in Slovakia. The study could contribute to help the agro-food companies' managers to improve the innovation activities and competitiveness of their companies, and it would be also helpful for public administration in the development of policies and instruments supporting innovations in the agro-food sector.
