The researchers analyzed cereal food production in Bangladesh over the past five decades. They found that advancements in technology and government subsidies led to increased production growth, despite a slowdown in area growth for certain types of rice. The study showed that previous year's land allocation for rice had a significant impact on the following year's allocation. Farmers considered factors like yield and price risk when deciding what crops to cultivate. The findings suggest that stabilizing market prices and developing stress-tolerant crop varieties are crucial for achieving sustainable food security in Bangladesh.
