The need for effective and rational use of land, protection, and preservation of its qualitative state (as the agricultural land soil) is due to some negative details, namely, more than a third of the land is eroded, half of which are black soil in particular, which have an average level of nutrient supply, a lot of contaminated abandoned or overdented land. The acuteness of this problem, which has developed with regard to the protection and preservation of the land qualitative state, has become particularly relevant. The solution to this problem requires truly effective methods of influence. One of such methods is the surveillance of ecological and economic monitoring of land. The article analyzes the ecological and economic factors and factors influencing the monitoring and surveillance of land in Ukraine. Perspectives and objectives for improvements in land monitoring are highlighted. The paper discloses a theoretical synthesis and new approaches to solving the problem of environmental management, which can participate in the development of innovative economic and environmental factors of rational land use, which will contribute to enhancing the transition of Ukraine to the model of sustainable land use. The purpose of this work is a scientific analysis of the various organizational factors of monitoring and surveillance of agricultural land in relation to the current legislation in Ukraine.

The small number of available complete modern pump characteristics makes the safety analysis of nuclear and conventional power plants based on the characteristics made over half a century ago of specific speeds n _q=24.6, 147.1 and 261.4. The aim of the paper is to check sensitivity of the power plant system response for different complete pump characteristics - modern and available from older tests for n _q=24.6, 147.1 and 261.4. It has been shown that Suter's characteristics for modern pumps give a different response to the pumping system of a power plant in breakdown than those used so far.
