- Key Developments:
- Introduction of crop rotation, enclosures, and selective breeding of livestock.
- Advancements in agricultural machinery like the seed drill by Jethro Tull.
- Improvements in transportation with the construction of canals and railroads, facilitating market access for farmers.
- Impact:
- Increased agricultural productivity, leading to the Industrial Revolution as surplus labor moved to urban areas.
- Expansion of food production to feed a growing population.
- Changes in land ownership and the rural social structure.
Green Revolution
- Time Period: Mid-20th century, particularly from the 1940s to the 1960s.
- Key Developments:
- Introduction of high-yield varieties of cereal grains, particularly wheat and rice.
- Use of modern irrigation, pesticides, and fertilizers.
- Mechanization of farming with the widespread use of tractors and other machinery.
- Impact:
- Significant increase in agricultural output, preventing famines in several countries.
