This publication captures forward-looking strategies, real-world applications, and regional policy directions that are shaping Southeast Asia's transition to digitally enabled food and agriculture systems. More than a record of discussions at the Roundtable Discussion Series on Sustainable Food and Agricultural Systems in Southeast Asia convened by the Southeast Asian Regional Center for Graduate Study and Research in Agriculture (SEARCA) and Bangko Sentral ng Pilipinas (BSP) in April 2023, the proceedings serve as a substantive knowledge resource for governments, agribusinesses, researchers, and development actors seeking to harness the power of digital platforms, artificial intelligence, mobile-based solutions, and big data to transform agricultural value chains.
