Adapting Ukrainian grain supply chains to the Russia-Ukraine war

Abstract The Russian invasion of Ukraine increased a threat to food security in countries that are not self-sufficient in grain production and largely dependent on Ukrainian grain imports. The level of grain production, the stable and efficient functioning of the grain market, and the interrupted supply chain are priority levers that determine the severity of this problem. This paper explores the impacts of the war on grain production and exports in Ukraine, in particular corn and wheat as major staples. The damage done to agricultural and transportation infrastructure, accompanied by interrupted export logistics, brings new challenges for participants in the grain supply chain in Ukraine. On a daily basis, they must adjust to the new landscape and market conditions that have caused changes in crop production within the country and grain exports geography. Redirecting export routes requires rapid decision-making to identify optimal ways to increase the efficiency of the grain industry. The application of the Knowledge Graph is a solution that helps lay out the optimal path from loading point (e.g., elevators) to destination point (e.g., port) bypassing damaged or dangerous areas and entering hubs for completing or disassembling grain trains to minimize risks, time and logistics costs.
