This study explores the role of supply chain agility in promoting sustainable procurement in the foodstuffs sector. It examines the mediating effect of system and process integration in operationalizing sustainable procurement applications. The research, conducted through structured questionnaires to key professionals within Saudi foodstuffs companies, uses Partial Least Squares Structural Equation Modeling (PLS-SEM) to evaluate the constructs of supply chain agility, sustainable procurement, system and process integration, and the effect of precise prediction on the effectiveness of the organization via the ARIMA technique. The findings suggest that supply chain agility significantly influences sustainable procurement, enabling organizations to create cost-saving opportunities in compliance with stringent environmental regulations.
