Southeast Asia must narrow down the yield gap to continue to be a major rice bowl

S. Yuan, A. M. Stuart, et al.

Southeast Asia, a significant player in rice production and exports, is grappling with yield stagnation and climate challenges. This groundbreaking study by renowned researchers reveals critical yield gaps, particularly in Cambodia, Myanmar, the Philippines, and Thailand, predicting dire domestic supply issues for Indonesia and the Philippines by 2040. However, there is hope: halving the exploitable yield gap could unleash a rice surplus for export. Dive into the insights that could reshape the region's agricultural future!

Abstract
Southeast Asia, a major rice producer and exporter, faces challenges from limited land, climate change, and yield stagnation. This study uses modeling to map rice yield gaps and assess production potential and net exports by 2040. Significant yield gaps exist, particularly in Cambodia, Myanmar, Philippines, and Thailand. Continuing current trends will leave Indonesia and the Philippines unable to meet domestic demand. However, halving the exploitable yield gap could create a substantial rice surplus for export.
