Ecosystem Approach in the Context of Economic Interest Management

The relevance of the study was conditioned by the necessity of seeking solutions of environmental security issues and ensuring its effective management. The purpose of the study was to structure the national security system with the allocation of environmental and economic subsystems, constructive and critical analysis of the main opinions and positions of researchers on the essence and areas of the ecosystem approach concerning the solutions of environmental security issues, further development of the ecosystem approach based on economic management methods. The study was based on the use of system and matrix approaches, methods of generalisation, modelling, analysis and synthesis, and content analysis. It was proved that the national security system includes, in particular, environmental and economic subsystems and that there is an objective internal system connection between these subsystems, which, if used correctly, should ensure the effective functioning and development of both subsystems. The study outlined the functional and subject matrix of the environmental security system, which will contribute to the systematisation of various areas in its research. It was established that from the standpoint of management theory, the ecological subsystem is defined as the managed one, and the economic subsystem is defined as the managing one. Management is ensured by the fact that the first one includes not only natural, but also human resources (consumers of ecosystem services, managers in the environmental sphere or performers of environmental functions). It was proved that the effective solution of environmental issues necessitates the consideration of the economic interests of these people, since economic interests constitute the basis of an economic (effective) management method. The practical value of the study was to develop an economic method for managing the environmental security system and substantiate the role of economic interests, which would contribute to the practical solution of environmental issues in Ukrain
