Conceptual basis of methodology of improving the technology of water use for irrigation and watering systems

The paper studies the formation and use of water resources on existing irrigation and watering systems (IWS) of Stavropol territory in cause-effect relation with the global problems of Energy, Water and Food defining the tendency of modern development of agricultural production thus meting the vital food needs in social development. Both at the level of the global system "Nature-Society-Person" within terrestrial biosphere and at its hierarchical levels of river basin geosystems, where water resources are formed, agricultural production is carried out on existing IWS, on the example of the Kuban, Terek and Lower Don rivers and with the population of over 23 million people, the modern social development is characterized by a stable tendency towards water finiteness in limited conditions for further development. The analysis of formation of water resources within the spatial limits of basin geosystems and their subsequent use on IWS determines the technological scheme of water use on irrigated lands. The problems of Energy, Water and Food in agricultural production on irrigated lands, as it was established in the processes of their systemic interconnection, interaction and relationship on current IWS of the Great Stavropol Canal have identified the dominant problem, according to which there is a need to take into account the geomorphological characteristics of the earth's surface topography, geological zoning of the Stavropol territory, development of the methodology to improve energy efficiency of water resources using both non-renewable and renewable sources of energy in accordance with system principles: "system integrity", "reflection of objective reality", "ecological suitability", "vital purposeful activity". Seven conceptual statements of Ecological Suitability contributing to new ideas for the creation of new and improvement of existing IWS were developed within the concept of "ecological suitability" for IWS operating within NTS "NE – IWS – P" based on basic system principles.
