New tools helped grow much more food. 

The Green Revolution was a time of big changes in farming. 


The Green Revolution was a major period of change in how the world grows food.
To make this revolution work, farmers used a specific set of new tools. 

The story began in Mexico during the middle of the twentieth century. 

Many important people led these scientific changes. Norman Borlaug is often called the "Father of the Green Revolution." He won the Nobel Peace Prize in 1970 for his work. He is credited with saving over a billion people from starvation. Another scientist, Yuan Longping, worked on hybrid rice to save many lives as well. 
You can see the impact of these changes in how we eat today. The Green Revolution spread from Mexico to places like India and the Philippines.
The Green Revolution was a period of intense technological change in global agriculture.
To achieve higher yields, farmers adopted a specific package of new practices. This process began with the use of high-yielding varieties of cereal grains. Scientists developed dwarf wheat and rice that could produce more food per plant. These new seeds required much more input than traditional varieties. Farmers had to use large amounts of synthetic fertilizers to support the plants. They also applied chemical pesticides to protect the crops from insects and diseases. 
This revolution was not a single event but a collection of different scientific developments. One major part was the hybridization of seeds to create stronger, more productive plants. Another part involved the expansion of massive irrigation infrastructure to manage water supplies. Modern management techniques and the distribution of hybridized seeds were also essential. In some regions, these changes were tied to economic policies. For example, developing nations often had to privatize the manufacture and distribution of fertilizers. This often required farmers to take out loans to afford the new technologies. 
The origins of the Green Revolution can be traced back to Mexico in the 1940s. In 1940, Henry A. Wallace visited Mexico and noticed very low corn yields. He observed that a Mexican farmer worked 500 hours to produce one bushel of corn. This was 50 times longer than the work required for a typical Iowa farmer. Wallace convinced the Rockefeller Foundation to fund an agricultural station in Mexico. This station focused on hybridizing corn and wheat for arid climates. 
Several key scientists led these efforts and changed the course of history. Norman Borlaug is known as the "Father of the Green Revolution." He received the Nobel Peace Prize in 1970 for his scientific contributions. Borlaug is credited with saving over a billion people from starvation. 
The impact of these changes was visible in massive production numbers. In Mexico, corn production tripled and wheat production increased five-fold within 20 years. By 1964, Mexico was exporting half a million tons of wheat. In the Philippines, annual rice production rose from 3.7 million to 7.7 million tons over two decades. These successes helped many nations achieve food self-sufficiency. However, the costs were not always easy to manage. By 1980, some credit schemes in the Philippines left poor farmers in debt. The benefits often went to rich landowners who could afford the expensive inputs.
The Green Revolution also created complex connections between science, society, and the environment. While it averted hunger, the use of pesticides could be hazardous to workers. The chemicals also sometimes damaged local ecology and contaminated waterways. These new methods also increased the world's reliance on synthetic nitrogen fertilizers.
