"The introduction of modern agriculture meant many different changes." Describe in four points.

1. Increasing Agricultural Productivity:

Intensive agriculture is one of the part of modern agriculture. This has led to increase in productivity and so increase in the national income and well being of the economy.

2. Health Hazards: 

Indian agricultre is the victim of its own past. Green revolution has led to increase in productivity. This has also led to threat to quality of drinking water due to use of chemical fertilizers.

3. Industrial Growth:

Increase in modern agriculture has led to more use of modern inputs such as tractors, electric motor, pumps, chemical fertilizers etc which has led to increase in industrial growth.

4. Development of organic farming:

Green revolution has led to diminishing results and increasing population has made  organic farming more popular.  It is an ancient method of cultivation. It will surely led to decline in our foreign exchange reserve due to low productivity.

The dramatic expansion of agriculture was made possible by new technology. This meant many new changes as follows:
(i) The open field disappeared. The increase in food production was not only possible by radical innovation in agricultural technology, it also needed new lands under cultivation.
(ii) The richer farmers expanded grain production, sold this grain in the world market, made profits and became powerful.
(iii) Modern technology and enclosure displaced the poor from the land. The poor found that their customary rights were gradually disappearing. Deprived of their rights they moved in search of jobs.
(iv) The poor left their village. They went to countries or cities where job was available, but jobs became insecure. They lived in fear of the loss of their livelihood.
Thus, we can conclude that the introduction of modern agriculture meant many different changes.
