Examines how changing rainy seasons affect rice production in Southeast Asia, implying urgent adaptation needs.

The aim is to analyze how shifts in the rainy season influence rice production in Southeast Asia due to climate change.
Utilized High-Resolution Model Intercomparison Project (HighResMIP) framework.
Combined rainfall data with the World Food Studies (WOFOST) crop model.
Analyzed changes in cumulative rainfall and rainy season characteristics across the region.
Observed a trend towards drier conditions during the dry season.
Cumulative rainfall decreased by up to 33% in mainland Southeast Asia during December-January-February.
Rainfall reductions during June-July-August were noted, reaching up to 48% in Indonesia.
Rainy season duration decreased by up to 27 days in southern Philippines.
Yield impacts varied; enhanced yields in GS-2 but reductions in GS-1 and GS-3, especially in Java.

Hariadi et al. (2026) studied this question.
