Reason for the decline of import of foodgrains:

- Green revolution: The main reason for the decline in the import of foodgrains was the Green Revolution. The Green Revolution refers to the period in the 1960s and 1970s when new agricultural technologies were introduced, leading to a significant increase in crop productivity. These technologies included the use of high-yielding varieties of seeds, irrigation, and fertilizers. As a result of the Green Revolution, countries were able to increase their domestic food production and reduce their dependence on imported foodgrains.

- Increased domestic production: With the adoption of new agricultural technologies, countries were able to produce more foodgrains domestically. The increased productivity allowed countries to meet their food requirements without having to rely on imports. This led to a decline in the need for importing foodgrains from other countries.

- Self-sufficiency: The Green Revolution helped many countries achieve self-sufficiency in food production. By producing enough foodgrains to meet their own needs, countries were able to reduce their reliance on imported foodgrains. This shift towards self-sufficiency further contributed to the decline in the import of foodgrains.

- Impact on trade balance: The decline in the import of foodgrains had a positive impact on the trade balance of countries. By reducing the need for importing foodgrains, countries were able to save foreign exchange and improve their trade balance. This allowed countries to allocate resources towards other sectors of the economy and promote overall economic growth.

In conclusion, the Green Revolution played a crucial role in the decline of import of foodgrains by increasing domestic food production, achieving self-sufficiency, and improving the trade balance of countries.
