Abstract

Summary

Purpose of the study was to develop a workflow for optimal water use estimation in croplands of Odesa region (Ukraine). The urgency of the climate-related problem is in focus of regional authorities after a prolonged drought followed by subsequent downpours in 2020 leading to loss up to 80% of sown cereals in the region. The suggested workflow consists of six steps: pre-selection of representative conditions, choosing the representative fields, collecting input data for model, simulation in AquaCrop model, model optimization with results extrapolation and recommendations development. We concluded that the application of a developed workflow for agricultural water balance assessment based on the combination of in-situ measurements, aerial observations, space-born data and model simulation will allow us to (i) estimate the current productivity/ water deficit at crop cultivation, (ii) extrapolate results to larger areas, (iii) develop recommendations for stakeholders on how to improve water use efficiency, avoid water stress in plants and increase yield productivity at field-to-regional scale. Also, those estimates might be of high demand by sectoral agencies and regional authorities in effective planning the limits of water supply for irrigation purposes to support appropriate yield productivity in Odesa region suffering from climate extrema over last years.
