GENERAL ASPECTS OF RESTORATION (RECONSTRUCTION) OF DRAINAGE SYSTEMS ON AGRICULTURAL LANDS (REVIEW OF PUBLICATIONS)

The article presents a review of publications on the actual problem of restoring the functional capacity of drainage systems, which in modern conditions of climate change and military aggression acquires special significance not only from the standpoint of the need to increase the productivity of drained lands, but also to ensure the water security of our country. The study of problems and setting of directions for restoration (reconstruction) of drainage systems in Ukraine and regions of the world was performed using bibliometric analysis. For analytical research, domestic and foreign literary sources of a 55-year period were studied, the main number of which falls on the period 2002-2022. The conducted analysis made it possible to determine the main directions that are considered when solving the problems of restoration (reconstruction) of drainage systems on agricultural lands worldwide and in Ukraine. Approaches to the operation, maintenance, and controlled decommissioning of drainage systems are based on the development of scenarios for the adaptation to climate change, therefore, the priority of the state policy in a number of countries is, first of all, the restoration of systems, which allows to ensure the adaptation of agricultural production to modern climate changes. Worldwide, the assessment of the reclamation fund is carried out constantly and the need for reconstruction and modernization of drainage systems is determined according to the design characteristics and technical condition also providing for the restoration of their water-regulating function. The basis for the reconstruction of drainage systems is the economic and technical justification of feasibility, the application of the progressive methods of drainage, the priority implementation of restoration measures in the areas of drainage systems, which are in working condition, and on the drained territories, where intensive and medium-intensity agricultural use of the drained lands is planned. The scientists' developments are aimed at creating economically viable technical options for the restoration (reconstruction) of drainage systems, which take into account the directions of their use and investment options for reconstruction. Studying the global experience of restoration (reconstruction) of drainage systems on agricultural lands and its use is important for the implementation of the provisions of the "Strategy of Irrigation and Drainage in Ukraine for the period until 2030".
