The Green Revolution is a production technology reform activity carried out by developed countries in the third world, with the main content being the cultivation and introduction of new high-yield rice and wheat varieties.

In the 1940s, the Rockefeller Foundation and the Ford Foundation in the United States sent agricultural experts to countries in Asia, Africa, and Latin America to set up various agricultural research centers to select and promote high-yielding varieties of rice, wheat, and corn, ushering in the green revolution.

In the early 1960s, the Foundation established the International Rice Research Institute (IRRI) in the Philippines, and within a short period of time, several new dwarf and high-yielding rice varieties were launched.

Since 1965, some new rice and wheat varieties have been gradually promoted to other developing countries.

The yield of these high-yielding rice and wheat varieties is 1 to 3 times higher than that of local varieties.

In the 1970s, it was implemented in more than 20 countries including India, Indonesia, and Pakistan.

In recent years, with the rapid development of genetic engineering, people have placed their hopes on the development of the second green revolution.

On the basis of the first green revolution, the 16th Ministerial Conference of the World Food Council in 1990 first proposed a new green revolution in developing countries.

Its main contents include: (1) Expand to other agricultural fields on the basis of consolidating the results of the first green revolution such as rice, wheat, and corn breeding; (2) While effectively utilizing irrigated land, expand to drylands, lowlands, hills and mountains

Expansion; (3) Expand the research and application of biotechnology and carry out the "gene revolution".

The use of genetic engineering technology to cultivate excellent varieties that are nitrogen-fixing, cold-resistant, high-temperature resistant, salt-alkali resistant, and disease-resistant will bring revolutionary changes to agriculture.

At present, the second green revolution has begun in the majority of developing countries and will play an important role in developing food production, improving productivity levels, and solving the problem of feeding hundreds of millions of people.
