Purpose. Reveal neo-ecological aspects of transformation the territorial structure of agrarian systems.
Methods. The method of generalization has been used in order to identify and study the monoprocesses of development that occur in territorial systems of different hierarchical levels.
Results. The retrospective analysis of the concept of «agrarian territorial system» has been evaluated. The essence of the concept of «monoagrarian territorial system» in the context of modern ecological problems had been specified. The peculiarities of the formation of the conceptual and terminological apparatus connected with agrarian monosystems in the theory of social geography have been given. Emphasis had been made on the involvement of scientists in various fields of knowledge in the formation of this apparatus. Attention has been focused on the study of agricultural systems in terms of generalization of their attributes to track the process of mono-development. The digital basis of the process of monodevelopment and the dynamics of absolute data of a certain type, which characterize the highest level of generalization, have been considered, as a rule, as a determinant characteristic of the object of study. The peculiarities of the coverage of the concept of "rural area" in the regulations of Ukraine have been analyzed. The disorder, heterogeneity, and contradiction of the essence of this concept in various normative legal acts have been established, because of which it is inconvenient to use it in all spheres of life of the population, including in the implementation of scientific research. The article analyzes the development of rural areas as monosystems of different hierarchical levels, and the process of their development is outlined as monodevelopment. It had ben noted that any numerical characteristic of the territory can become a starting point for a specific process of monodevelopment that takes place within it. That is, even in the absence of dynamic data, but in the presence of the possibility to compare the starting points of the various processes of development of such monorosystems, we can predict the peculiarities of their course in the study area. The importance of research of monoprocesses (generalized at the regional level) through the analysis of indicators the cost of the made agriculture production had been outlined; the cost of agricultural products sold by enterprises; the number of employees in Ukraine in general and in agriculture, forestry, and fisheries in particular; use of agricultural products.
Conclusions. The study proves the need for comprehensive coverage of the peculiarities of rural development focuses on the inadequacy of studying the course of any one monoprocess within them, or even several processes. The importance of studying such processes against the background of the transformation of the territorial structure of agricultural systems operating in the context of neo-globalization challenges has been emphasized. This scientific approach made it possible to understand the essence of the development of rural areas as monosystems and to identify the features of them further in the context of neo-environmental aspects. The conceptual and terminological apparatus in a specific socio-geographical study was first supplemented by the category of "mono-agrarian locality" with the author's interpretation of its essence.
