Abstract
The article deals with the issue of reducing the efficiency of agricultural production on reclaimed lands in the Polesie zone of Ukraine under the conditions of climate change. An overview of the key trends and consequences of climate change in Ukraine, which directly affect the conditions and results of agricultural production, was carried out. Including on the reclaimed lands of the Polesie zone, which are of strategic importance as a critical resource for ensuring and maintaining the country’s food and water security in the current conditions. The results of the analysis of long-term data on the cultivation of the main agricultural crops on the reclaimed lands of the Polesie zone of Ukraine for the period 1980–2018 indicate the presence of a tendency to decrease the yield of cultivated crops. To determine further prospects in relation to retrospective results, a predictive assessment of the impact of climate change on the productivity of the main agricultural crops was performed. The predictive assessment showed the threat of a possible decrease in yield on average from 15 to 60% in the case of compliancewith the existing approaches and practices of using reclaimed land in the Polesie zone. In this regard, prospective measures for the development of appropriate strategies for further development have been defined, including the implementation of adaptive resource-saving measures, which foresee the need for changes in varieties and the introduction of agricultural crops resistant to threats (primarily regarding temperature and water regimes). Including the implementation of adaptive resourcesaving measures, which foresee the need for changes in varieties, the introduction of agricultural crops resistant to threats (primarily regarding temperature and water regimes), and foremost, the implementation of technologies and regimes of water regulation on drained lands improved on ecological and economic principles
