Agriculture growth i.e. production in food grains directly supports the food security. It also supports in poverty reduction and act as the prime source of the economic growth in many developing countries such as, India and South-East Asian countries.
In the last 50 years world population has increased from 3.7 billion in 1969 to 7.7 billion in 2019 with density of population per square kilometer increased from 25 to 52 ( more than double) in the last 50 years.

There still continues the food insecurity in several parts of the world and there is rising demand of food grains with increasing population in the world.
