Overview​

The Green Revolution significantly boosted food production through agricultural advancements such as fertilizers, pesticides, and irrigation methods. However, these techniques led to environmental issues like soil degradation and water contamination. Sustainable rice production methods, such as no-till farming, can reduce carbon emissions and maintain soil health. The International Rice Research Institute (IRRI) plays a crucial role in pioneering advanced rice cultivation techniques, including precision farming and organic fertilizer application.
