A recent study by the University of Illinois Urbana-Champaign has revealed that global rice production nearly doubled between the 1960s and the 2010s. This growth happened despite the negative effects of climate change. The study highlights that human efforts, especially better farm management, played a major role in increasing production.
The research, led by Professor Atul Jain and former graduate student Tzu-Shun Lin, combined real-world data and advanced modeling. It examined how environmental changes and farming practices have influenced rice production over the past fifty years. The findings were published in the journal Scientific Reports.
“Rice sits at the intersection of food security, economic development and environmental change,” Jain said. “Today, most of the world’s rice grows in Asia, with China, India and countries across South and Southeast Asia accounting for the largest share of global production.”
Unlike earlier studies that focused only on climate or carbon dioxide levels, this research considered multiple factors together. These included irrigation, fertilizer use, manure application, growing seasons and different planting methods. This broader approach helped researchers better understand what truly drives rice production.
“The decisions made by farmers, industry and policymakers have been instrumental in sustaining rice production and improving food security for billions of people,” Jain said. “Our study shows that the increase in rice production was driven primarily by management decisions — in the form of expanded irrigation, increased nutrient inputs and adoption of farming practices that helped farmers grow more rice — rather than by climate change.”
However, the study also found that climate change has had negative effects. It reduced global rice production by about 7 percent between 2006 and 2015 due to higher temperatures, heat stress and water shortages. In contrast, rising carbon dioxide levels helped increase production by improving plant growth and water use.
“Food security and environmental sustainability must be addressed together,” Jain said. “This is critical, as our study shows that climate change is already affecting rice production in some of the world’s most important rice-growing regions. India experienced the largest climate-related rice production losses, followed by Indonesia and China, highlighting the importance of developing management strategies that can sustain rice production while adapting to increasing climate pressures.”
The researchers plan to continue studying ways to meet future rice demand while improving sustainability. Their goal is to balance food production with environmental protection and climate resilience in agriculture.
