Abstract

Relevance of research. As a result of row of reasons of socio-economic character, there has been a decrease in volumes and a decrease in the efficiency of the use of drained land over the last two decades, primarily within river floodplains. The purpose of the study is to determine the prospects and problems of the development of reclaimed areas of the Irpin river floodplain under transformed climatic conditions and the nature of land use. Research methods - field surveys, monitoring observations of water levels in canals and groundwater levels, systematic and cartographic data analysis and hydrological calculations. Research results and main conclusions. Based on the research findings in the typical pilot territories of Irpin’s drainage-irrigation system (DIS), the current state and main problems of the use of drained lands within the Irpen’s river floodplain are characterized, as well as the prospects for the further development of reclaimed floodplain areas during the transformation of climatic conditions and land use are determined.  It has been established that significant factors influencing the decrease in the level of use of drained agricultural land of the floodplain for its intended purpose are the fragmentation of land shares, the limited financial capabilities of their owners, the nationwide tolerance for long-term non-use of reclaimed lands, as well as the tendency to increase the number of peat fires and floodplain buildings development.

It was determined that the unsatisfactory technical condition of a significant part of the on-farm drainage canals of the Irpin’s DIS, the majority of hydrotechnical water control structures on them, siltation of the estuarine parts of closed drainage collectors and a decrease in the depth of its occurrence in areas with peat deposits due to their runoff, precipitation, mechanical removal and burning out ensuring a favorable water regime of soils and protection of the agricultural lands from flooding on the floodplain of the Irpin’s River without redesign or modernization of the DIS. It is noted that the perspective direction of the use of drained floodplain lands is the cultivation of berry crops with an application of drip irrigation. I

It is determined that, taking into account the potential negative water and environmental consequences of housing, especially multi-story, floodplain development, its use as a town-planning resource should be geographically limited and aimed primarily at creating of recreational areas and to be carried out in compliance with the requirements of water and land legislation.
