The article is devoted to the analysis of the current state of the legislation of Ukraine in the field of hydraulic reclamation of lands, as well as to highlight the prospects for the development of legal support of the outlined sphere of public relations. It is established that hydraulic reclamation of lands contributes to increasing soil fertility, increasing productivity and sustainability of agriculture, creating a guaranteed food fund of the state. However, in recent years, the effectiveness of hydraulic land reclamation is declining, due to a number of reasons of objective and subjective nature: insufficient logistics and shortcomings in the operation of hydraulic structures, deterioration of ecological and reclamation of agricultural land, lack of interest and responsibility land users. These factors include incomplete use of scientific developments, insufficient information support, imperfect and outdated legal framework. Given the great importance of hydraulic land reclamation for the development of agriculture in the country, these relations require proper legal regulation. It is concluded that the problems of combating desertification, resource and food security of the state in years with adverse weather conditions, water supply of agriculture cannot be solved only by organizing land reclamation, because this problem is complex. In order to achieve the goals of the Irrigation and Drainage Strategy in Ukraine for the period up to 2030, it is necessary to ensure effective interaction of legal, organizational, economic and financial mechanisms of irrigation and drainage restoration in Ukraine within the framework of the identified priority areas.
