The methodological vision of the formation of the state economic policy, based on the needs of society sustainable development was proposed; the methodology for analyzing the impact of economic and environmental indicators of the implementation of the state economic policy, as an alternative to decoupling analysis was developed. Methodology. Methodological basis is formed by the convergence of four methodological approaches: methods of evaluation of indicators of "green" growth of the OECD; National System of Sustainable Development; methodological support for determining the economic and environmental priorities of "green" economy in the context of sustainable development; normative approach to the evaluation of parameters of economic safety of the state. Results. The proposed methodological support was approbated on the example of Ukraine in the period from 2010 to 2018. Practical approbation of the methodology allowed us to determine the cause-and-effect relationships between the dynamics of changes in economic and environmental indicators, positive and negative trends in the process of environmental transformation of economic policy. Value/originality. The original feature of the author's methodology is a logical and structural analysis of the main factors influencing the components of resource and environmental productivity of GDP and an extended diagnostic procedure.

Water recirculation systems in aquaculture, also known as RAS (Recirculating Aquaculture Systems), represent a new alternative to traditional fish farming methods with several important advantages. These human-controlled systems provide efficient water conservation, fish health preservation, and increased productivity.

Introduction. Sustainable development of mariculture as a highly productive industry is a potential and source of income and contributions to the national economy, a guarantee of food and environmental security, socioeconomic benefits for coastal areas. The effective development of mariculture requires a stable basis as an institutional support, which, unfortunately, is not characterized by a high enough level in Ukraine. Aim and tasks. The aim of the study is to analyze and evaluate the institutional support for the development of mariculture in Ukraine and the implementation of international experience in national practice. The main tasks of the study are: to study the features of theoretical and applied ukrainian context of mariculture development to determine the possibilities of implementing international experience; to analyze ukrainian and international institutional basis for the development of mariculture and the cultivation of marine organisms; to develop conclusions and recommendations on the current state and development of institutional support for mariculture in Ukraine on the basis of compliance with international requirements and the possibility of their implementation. Results. The concept of mariculture is theoretically substantiated by its definition in texts of the legal framework. The analysis of the ukrainian and international institutional context of mariculture development is based on the procedure of measures on the development of institutional support for mariculture in Ukraine in the context of the implementation of international experience of world leaders in mariculture development, European Union countries, and countries with short traditions of marine cultivation. Conclusions. A detailed interpretation of the concept of mariculture for its definition in the texts of the legal framework of Ukraine based on the characteristics of the industry presented in the legal documents of Ukraine, the European Union, world leaders in mariculture, dictionaries and works of prominent Ukrainian and foreign scholars. A procedure for measures to develop institutional support for mariculture in Ukraine in the form of an algorithm for implementing the international experience of world leaders in mariculture, the European Union and countries with short traditions of marine organisms.

Introduction. The world is aware of the importance of preserving natural resources and is shifting its focus to a social perspective, reflecting the acceptance of sustainable development principles. Aquaculture management must consider the impacts on the ecosystem and community, ensuring a balance in the use of water resources. Aquaculture can become a sustainable way to generate economic resources, and has recreational and cultural applications. This study examines the possibilities of using aquaculture in educational and cultural activities, public leisure, aesthetic education, and the development of park areas, as well as for other multifunctional purposes that contribute to improving water environment management and creating new ecological jobs. Aim and tasks. The study aims to develop a conceptual vision of multifunctional aquaculture facilities as innovative and recreational centres for new jobs and the development of the local economy, considering socio-ecological and economic motivational mechanisms and effects that have not been previously investigated. Results. The variability of directions for the development of aquaculture activities in the context of implementing marine strategies, Sustainable Development Goals, and reduction of the negative consequences of water pollution due to military actions. Socio-ecological and economic motivational mechanisms have been developed to form aquaculture facilities as centres of a green corridor or a concentration of ecologically safe zones to integrate them into urban and rural spaces. Measures for integrating aquaculture into tourism activities and the scientific concept of the concentration of ecologically safe territories with an aquaculture core in terms of organizational measures and possible effects are proposed. Conclusions. A conceptual vision of multifunctional aquaculture facilities with the functions of reproduction, education and cultural-recreational enlightenment in terms of scientific and educational, decorative and circular facilities was proposed. The scientific concept of the concentration of ecologically safe territories with an aquaculture core in terms of organizational measures and possible effects was proposed.

Introduction. The key role in maintaining the competitiveness of economic systems belongs to the innovative specialization of economic activity, which diversifies economic activity. The existing methodological approaches to determining the strategic priorities of Smart Specialization of a particular region do not fully take into account the assessment of innovation and investment potential, taking into account the environmental component of sustainable development. Aim and tasks. The purpose of the proposed study is the formation of scientific approaches to assessing innovation and investment potential in the context of the formation of strategic regional environmental policy in the context of the methodology of Smart Specialization. Results. The article substantiates the methodological provisions for combining the methodology of Quintuple helix, Smart-specialization and Sustainable Development Goals. The institutional essence of investment and innovation policy of nature management at the regional level as a modern model of Quintuple helix is determined. An assessment of the innovation potential of the regions as a component of investment and innovation policy of nature management. The dynamics of implementation of environmental innovations by enterprises of Ukraine, the concentration of higher education institutions by regions, in particular, subordinate government agencies are analyzed. The number of students, specialists in higher education institutions majoring in natural sciences, employment in the field of nature management has been determined. The strengthening of the ecological component in the scientific and educational spheres is established for the further implement the borrowed knowledge in the formation of investment and innovation policy of nature management of individual regions. The natural resource potential of the country in terms of regions according to the statistical database is studied. Conclusions. The presented research proposes the author's vision, which allows not only to outline the dominants of Smart Specialization of кegions in order to determine the strategic priorities of investment and innovation policy of the national sphere of nature, but also to explore the uniqueness of regions based on scientific and technical potential. Implementation of the Smart Specialization Strategy, which will combine the methodology of Quintuple helix and Smart Specialization will provide an opportunity to determine the approach to the formation and implementation of state regional policy. A methodological approach to determining the dominants of investment and innovation regional environmental policy has been developed, taking into account the methodology of "Smart Specialization" and in the context of existing European experience.
