What started the modern Agricultural Revolution?
A. New types of crops
B. Improved farming methods
C. Greater demand for food
D. More fertile soil
The Correct Answer and Explanation is:
The correct answer is A. New types of crops.
The modern Agricultural Revolution, commonly known as the Green Revolution, was initiated primarily by the development and introduction of new types of crops, particularly high-yielding varieties (HYVs) of staple grains like rice and wheat. This transformation began in the mid-20th century, particularly from the 1940s to the 1960s, when agricultural scientists and researchers focused on breeding new crop varieties that could significantly increase food production.
The most notable figure in this movement was Norman Borlaug, often referred to as the “Father of the Green Revolution.” His work in Mexico led to the development of dwarf wheat varieties that were resistant to disease and had higher yields. These crops not only produced more grain but also allowed for shorter growing seasons, enabling farmers to cultivate multiple harvests within a single year. This advancement was crucial in addressing food shortages in developing countries and laid the foundation for increased agricultural productivity worldwide.
In addition to introducing new crop varieties, the Green Revolution encompassed improved farming methods, such as the use of chemical fertilizers and pesticides, modern irrigation techniques, and mechanization of agricultural practices. While these improvements were essential for maximizing the benefits of the new crops, the core driver of the revolution was indeed the introduction of these innovative crop varieties.
Furthermore, the increased global population created a greater demand for food, prompting the need for enhanced agricultural practices. However, it was the combination of new crop types and the methods developed to support them that ultimately led to significant increases in food production and helped avert widespread famine in many parts of the world. Therefore, the introduction of new types of crops is fundamental to understanding what sparked the modern Agricultural Revolution.
