Final answer:
The statement is true: the Green Revolution refers to the significant advancements in agricultural practices, including the development of high-yielding varieties of wheat and rice, that dramatically increased global food production and helped prevent a predicted global famine.
Step-by-step explanation:
True, the dramatic increase in yield due to the introduction of high-yielding varieties of tropical wheat and rice across the globe was indeed called "the Green Revolution". This phenomenon began in the 1940s in Mexico and spread worldwide during the 1950s and 1960s, continuing to influence agricultural trends into the 1970s. Innovations such as high-response varieties (HRV) of crops, expansion of irrigation, and an increase in the use of artificial fertilizers and pesticides greatly improved global food production.
The Green Revolution was crucial in averting a global famine that had been predicted in the late 1960s, as it led to a significant improvement in agricultural yields. At the heart of the revolution were the efforts of Norman Borlaug, who developed high yielding dwarf wheat and rice varieties, which were less susceptible to lodging and featured enhanced disease resistance and higher tolerance to extreme weather conditions, contributing to a substantial increase in crop yields.
While the advances made during the Green Revolution led India to become a net exporter of wheat and saved vast tracts of land from being converted into farmland, it has also been critiqued for the negative social and environmental impacts, such as widening social inequality and farmer indebtedness among others.
