The Green Revolution refers to a period of significant agricultural transformation that began in the 1940s and continued into the 1960s. It involved the introduction of high-yielding varieties of crops, particularly wheat and rice, along with the use of chemical fertilizers, pesticides, and advanced irrigation techniques. This movement aimed to increase food production and combat hunger, especially in developing countries. Key figures in the Green Revolution include Norman Borlaug, often called the "father of the Green Revolution," who developed disease-resistant wheat varieties. The revolution led to substantial increases in crop yields, particularly in countries like India and Mexico, helping to alleviate food shortages and improve food security.
