Do you expect climate-related crop declines to increase food prices in your area?
A study released by the Singapore Food Agency and the National University of Singapore reveals that climate change will trigger significant fluctuations in crop production across Southeast Asia. While staple crops like rice, maize, and sugarcane face declines, others such as cassava and soybeans are expected to see notable growth.
Why it matters
Rising temperatures and variable rainfall patterns are disrupting water availability and planting schedules for farmers. The study highlights the vulnerability of rain-fed systems and the compounding threat posed by extreme weather events like El Niño.
Researchers estimate that very strong El Niño events reduce regional crop production by up to 10 percent. Projections for 2025 through 2044 show maize output falling by 5 to 6 percent and sugarcane production dropping by 1 to 4 percent.
The players
Singapore Food Agency
This government board oversees food safety and security standards within Singapore.
National University of Singapore
This is a leading public research university based in Singapore that partners on regional policy studies.
The details
The report, titled ASEAN Agri Climate Impact Twenty, outlines how extreme heat, heavy rainfall, and drought cycles directly impact production variability. These environmental stressors threaten the reliability of regional food systems that depend heavily on stable seasonal weather.
Timeline
The ASEAN Agri Climate Impact Twenty study was released on October 29, 2026.
Projected crop production shifts are expected to occur between 2025 and 2044.
Market Landscape
This study underscores how climate-driven shifts in crop viability necessitate a broader realignment of regional agricultural focus. The projected growth in cassava and soybean production suggests a pivot toward more climate-resilient commodities as traditional staple crops face increased cultivation risks.
Readers may see shifts in the price and availability of regional staples as supply chains adjust to changing production levels. Households should anticipate potential market volatility for rice and maize as environmental pressures impact regional harvest consistency.
The takeaway
Farmers and food distributors must prioritize crop diversification to buffer against the projected decline in traditional staples. Implementing drought-resistant agricultural techniques is essential for maintaining stability in rain-fed farming systems as weather variability intensifies.
