Chapter summary
Key ideas & terms
- Net area sown
- The physical extent of land on which crops are sown and harvested.
- Common property resources
- Community natural resources owned by the state, where every member has rights of access and usage.
- Cropping intensity
- Gross cropped area expressed as a percentage of net sown area, showing how intensively land is used.
- Kharif, rabi and zaid
- India's three cropping seasons — the monsoon kharif, the winter rabi and the short summer zaid.
- Green Revolution
- The rapid rise in foodgrain output from HYV seeds, irrigation, fertilisers and pesticides from the mid-1960s.
- Dryland farming
- Rainfed farming in regions with under 75 cm annual rainfall, growing drought-resistant crops like ragi and bajra.
Extra questions & answers
Differentiate between barren and wasteland and culturable wasteland.
Barren and wasteland, such as deserts and ravines, cannot be brought under cultivation with available technology, while culturable wasteland is land left fallow for more than five years that can be reclaimed for cultivation.
How would you distinguish between net sown area and gross cropped area?
Net sown area is the physical land on which crops are sown and harvested, while gross cropped area counts the same land more than once if it is cropped more than once in a year.
Why is the strategy of increasing cropping intensity important for India?
Because the scope for adding new land is limited; raising cropping intensity makes fuller use of scarce land, increases output and creates more rural employment.
How do you measure total cultivable land?
Total cultivable land is obtained by adding net sown area, all fallow lands and culturable wasteland.
What is the difference between dryland and wetland farming?
Dryland farming, in areas with under 75 cm rainfall, grows hardy drought-resistant crops with moisture conservation, while wetland farming, where rainfall exceeds plant needs, grows water-intensive crops like rice and sugarcane.
What are common property resources?
They are community natural resources owned by the state, where every member has rights of access and usage, providing fodder, fuel and minor forest products especially to the poor.
Name the three cropping seasons of India.
The kharif season coinciding with the south-west monsoon, the rabi winter season, and the short summer zaid season.
What were the important strategies for agricultural development after independence?
Switching from cash to food crops, intensifying cropping, expanding cultivated area, and later the Green Revolution using high-yielding varieties, irrigation, fertilisers and pesticides.
Discuss the major problems of Indian agriculture.
Dependence on erratic monsoon, low productivity, financial constraints and indebtedness, lack of land reforms, small and fragmented holdings, lack of commercialisation, vast underemployment and land degradation.
What are the different environmental problems of land resources in India?
Land degradation through soil erosion, waterlogging, salinisation and alkalisation, especially in irrigated areas, and erosion by water and wind in rainfed humid and semi-arid tracts.
