Sustainable Agriculture: All green plants synthesize their own food from carbon dioxide and water in the presence of sunlight. The energy needed for this comes from the sun. Green plants are called autotrophs because they synthesize their own food. Those organisms (nongreen plants and all animals) which cannot synthesize their own food are called heterotrophs.
Indian scientists have been able to increase foodgrain production. They have introduced improved varieties of crops. Crops are plants grown in large quantities for food or other needs. The introduction of improved varieties crops, better agricultural methods and irrigation facilities resulted in an increase in the production of foodgrains. This was through a country-wide programme called Green Revolution in the late 1960s.
Sustainable agriculture: With the increase in human needs, there is a need to increase food production without upsetting the balance in nature. The practice of cultivating land using such methods that yield sufficient crops, but do not harm the environment is called sustainable agriculture.
