Short Summary

This study analyzes and updates crop water consumption rates for irrigation in Ukraine, considering climate change, by developing an automated information system and revealing significant increases in water demand across different climatic zones.

Objective

• To analyze existing approaches and update crop water consumption rates for irrigation in Ukraine, accounting for climate change and the need for constant revision using information technologies.

Study Configuration

• Spatial Scale: Ukraine (regional, weather station level, Steppe, Forest-Steppe, and Polissya zones).
• Temporal Scale: Analysis period 2005–2024; comparison with control climatic period 1960–2000.

Methodology and Data

• Models used: Biophysical Shtoiko method, Penman-Monteith-Leuning method (for evapotranspiration components), water balance equations, Thyssen-Voronyi polygon method (for weather station influence zones). Python software developed using Folium, Shapely, and Django libraries for data analysis and visualization.
• Data sources: Meteorological data from regional automatic weather stations, multi-year series of agricultural and meteorological observations, remote sensing data, information systems developed at the Institute of Water Problems and Land Reclamation.

Main Results

• Water need for growing crops in Ukraine has significantly increased, particularly in southern regions.
• Water consumption rates for crops in Ukraine increased significantly over the past two decades compared to 1960-2000.
• Specifically, water consumption increased by 40% in the Steppe zone and by 15% in the Forest-Steppe and Polissya zones.
• Analysis for 2005-2024 confirmed a further average increase of 18-25% in water consumption across all climatic zones.
• Maps of water consumption deficits for the warm period and water consumption rates for corn and wheat (for 50%, 75%, and 95% water supply deficit) were built, showing regional variability.
• The study confirmed the necessity for continuous updating of water consumption rates for agricultural policy and water management planning.

Contributions

• Development of an automated information system and web tools for calculating and visualizing updated crop water consumption rates in Ukraine.
• Creation of an interactive database of crop water consumption rates integrating geospatial parameters.
• Quantification of the significant increase in crop water consumption rates across different agro-climatic zones of Ukraine due to climate change.
• Provision of spatially distributed cartographic information on water consumption deficits and rates for key crops.
