In the 1960s, India produced only about 10 million metric tonnes of wheat annually, and crop failures created massive food shortages that required emergency shipments of grain to prevent widespread famine. Today, India produces over 70 million metric tonnes of wheat. This is due in large part to the success of the Green Revolution, based on new genetic improvements of crops combined with efficient use of crop production inputs. However, food security remains a global challenge today and famine still threatens several parts of the globe. [...] Often called the Gene Revolution, advances in biotechnology are having dramatic impacts on global agricultural production.
