5. The main crop grown in India is rice, subsistence crop
Subsistence farming -food grown to feed the family, no
surplus remaining to sell for a profit.
Rice growing requires:
• Warm, wet climate perfect
• heavy rainfall (during the Monsoon rains from May to
September)
• temperatures above 24°C all year.
These farms require
lots of manual labour,
have very small field sizes
little or no technology: farmers cannot afford
high-tech equipment
6. Most farms are small and family run.
plots often scattered around the village
use oxen to plough the fields,
manual labour to harvest the crop.
Soil bunds are walls built to retain the water in the
flooded paddy fields
also needs to be a source of water ( eg, nearby river
or stream.
17. millions of people migrating to towns
and cities in search of jobs that don't
exist, because the mills are closed, the
factories are shut, and hundreds of
thousands of units have wound up.
The 1968 Green Revolution
saw annual wheat
production rise from 10
million tonnes to 17 million
virtually overnight, and
continue to increase to a
point where it now stands at
73 million tonnes.
the Indian government is
seeking to import three
and a half million tonnes of
wheat this year, to boost
dwindling reserves
"We don't get anything out of wheat or
rice, but we get good prices for
mushroom," said one farmer who has
switched from growing wheat.
The water level has gone down - we
don't get enough water to irrigate the
fields,"
Now, farmers are opting for
mushrooms and sweet corn

•Machines allow work to be done more quickly (1).
•Machines also make the work easier (1).
•Increase in the amount of crop produced (1) and
•also the quality (1).
•Possibility of growing two crops or more each year (1).
•Some farmers cannot afford the new machines etc (1).
•Increased use of machines may lead to unemployment in
rural areas (1);
•may result in rural depopulation (1).
•Increased use of fertilisers could ruin the soil in the long
term (1)
•and may also result in river pollution (1).
