Title: Food security in conditions of water scarcity
The largest rice agro-complex located in the Kuban River basin (more than 160 thousand hectares of sown area) nowadays faces the water scarcity problem due to a regular low water periods. During the agro-complex operation period, there was a decrease in the reservoirs live storage, as well as stable changes in the flow dynamics and volumes of mountain rivers due to climate change.
In the low water periods, the limitation of normal water consumption in the basin reaches 20% or more, which causes significant damage to all water users. In addition, in 2022, the disruption of the retaining hydroelectric complex operating mode, which provides water supply to 4 large rice irrigation systems, led to an increase in the shortage of irrigation water, which negatively affected rice yields.
The solution proposed by the authors to the problem of improving water supply and water use of irrigation systems is based on the development of an integrated system for managing the distribution of water resources, considering the efficiency of its use by agricultural producers. Control technology is based on two interrelated optimization problems solved in the same spatial and temporal format: with the help of a dynamic hydraulic model, optimal options for supplying irrigation water from water sources to a water user are formed and studied, and productivity models are evaluated the impact of water supply parameters on crop yields, considering the technical parameters of the on-farm irrigation network using production functions. Hydrodynamic modeling makes it possible to form the reservoirs and hydroelectric facilities operation modes to ensure, on the one hand, operating levels at water intakes, and, on the other hand, satisfy the conflicting interests of water users. The development of an acceptable management decision is focused on the forecast of crop shortages depending on the water dividing option.
Alina Buber has completed her PHD in 2021 in All-Russian Research Institute of Hydraulic Engineering and Land Reclamation named after A.N. Kostyakov, Moscow, Russia. She is the senior researcher of Reclamation and water management department of VNIIGIM. She has over 80 publications, including in foreign journals, that have been cited over 180 times, and her publication h-index is 7.
She experienced with hydrodynamic models’ development in the MIKE 11 software for managing water resources of large river basins - Volga, Don, Kuban, Angara. Developer of the simulation model of early potato crop formation "POTATO" for managing different irrigation types and soils water regime in arid zone conditions. Conductor of young scientists’ expeditionary research in the Krasnodar Territory and the Volgograd Region, aimed at developing scientifically-based measures for the sustainable agricultural complexes functioning in conditions of water scarcity.
During her science career she received different awards, such as: Certificate of Honor of the Union of Water Workers and Reclamators; Silver medal «The Best Young Scientist-Reclamator» in the competition of the 21st Russian Agro-industrial exhibition "Golden Autumn - 2019"; the medal «The Best Young Scientist – 2020» of the Commonwealth of Independent States.
