Land Resources and Agriculture

Introduction

Land is utilized for various purposes: production, residence, and recreation.
Examples of land uses include schools, roads, parks, fields, and pastures.

Land Use Categories

Maintained by the land revenue department.
Categories contribute to the reporting area, differing from geographical area measured by the Survey of India.

Categories of Land Use:

Forests
- Actual forest cover differs from area classified as forest.
- Government demarcates area for forest growth.
Barren and Wastelands
- Includes barren hilly terrains, desert lands, and ravines.
- Typically unsuitable for cultivation with current technology.

Changes in Land Use (1950-51 to 2019-20)

Significant changes in land use categories over decades.
Key Observations:
- Increase in areas under non-agricultural use due to economic changes.
- Increase in forest area classified, not necessarily actual forest cover.
- Fluctuations in current fallow lands due to rainfall and cropping cycles.
- Recent increase in net area sown due to use of culturable waste land.

Conclusion

Understanding land use is crucial for managing resources and planning for agricultural development.

CBSE Exam Tips, Important Questions & Common Mistakes to Avoid

Common Mistakes and Exam Tips

Common Pitfalls

Misunderstanding Land Use Categories: Students often confuse the definitions of barren land, wasteland, and culturable wasteland. Ensure clarity on these terms.
Confusing Reporting Area with Geographical Area: Remember that reporting area can change based on land revenue records, while geographical area remains constant.
Assuming Increase in Forest Area Equals Increase in Forest Cover: An increase in the area classified as forest does not necessarily mean an increase in actual forest cover.
Neglecting the Impact of Economic Changes on Land Use: Changes in the economy can significantly influence land use patterns; be aware of how these shifts affect agricultural land.

Exam Tips

Review Land Use Categories: Familiarize yourself with the different land use categories and their definitions as per land revenue records.
Understand the Importance of Current Fallow: Be prepared to explain how current fallow lands fluctuate due to rainfall and cropping cycles.
Analyze Changes Over Time: Practice comparing land use data from different years, focusing on the implications of increases and decreases in various categories.
Use Diagrams: If applicable, practice interpreting diagrams that show changes in land use over time, such as the one depicting changes from 1950-51 to 2019-20.

True or False

Correct Answer: True

Solution:

The land revenue records reflect the area classified as forest by the government, which may differ from the actual forest cover.

Correct Answer: True

Solution:

The Green Revolution initially focused on irrigated areas, leading to regional disparities in agricultural development.

Correct Answer: False

Solution:

Land-use records are maintained by the land revenue department, not the Survey of India.

Correct Answer: True

Solution:

The expansion of urban and rural settlements, along with industrial and infrastructural development, has increased the area under non-agricultural uses.

Correct Answer: False

Solution:

The yield of sugarcane is actually lower in northern India compared to other regions like Maharashtra, Karnataka, Tamil Nadu, and Andhra Pradesh.

Correct Answer: True

Solution:

In irrigated areas, the degradation of land resources is mainly caused by alkalisation and salinisation, along with waterlogging.

Correct Answer: False

Solution:

The productivity of crops in India is generally lower compared to international levels, including the U.S.A., Russia, and Japan.

Correct Answer: True

Solution:

The increase in net area sown is a recent phenomenon due to the use of culturable wasteland for agricultural purposes.

Correct Answer: False

Solution:

The increase in the share of forest area is due to an increase in the demarcated area for forest growth, not an actual increase in forest cover.

Correct Answer: True

Solution:

The yield of crops in India is low compared to international levels, with lower per hectare output for crops like rice, wheat, and cotton.

Correct Answer: False

Solution:

Barren and wastelands, such as barren hilly terrains and desert lands, normally cannot be brought under cultivation with the available technology.

Correct Answer: False

Solution:

The yield of sugarcane is higher in the southern regions of India compared to the northern regions.

Correct Answer: True

Solution:

The increase in the net area sown is attributed to the conversion of culturable wasteland into agricultural land, reversing a previous trend of decline.

Correct Answer: False

Solution:

The degradation of cultivable land in India is largely due to human-induced factors such as faulty irrigation strategies, excessive use of chemicals, and changes in cropping patterns.

Correct Answer: False

Solution:

The land revenue records reflect the area classified as forest by the government, which may differ from the actual forest cover.

Correct Answer: True

Solution:

Net sown area refers to the actual land area where crops are planted and harvested, as defined in the land use categories.

Correct Answer: True

Solution:

The success of high yielding varieties (HYVs) of seeds depended on the assured supply of soil moisture through irrigation.

Correct Answer: True

Solution:

Net sown area is defined as the physical extent of land on which crops are sown and harvested.

Correct Answer: True

Solution:

The introduction of high yielding varieties (HYVs) of wheat and rice was a key component of the Green Revolution in India.

Correct Answer: True

Solution:

The Green Revolution was initially confined to irrigated areas, leading to regional disparities in agricultural development until the technology spread to other parts of the country.

Correct Answer: False

Solution:

Degradation of land resources is largely due to faulty irrigation strategies and excessive use of chemicals, leading to issues like alkalisation, salinisation, and waterlogging.

Correct Answer: False

Solution:

The increase in forest area in India is due to an increase in the demarcated area under forest, not an actual increase in forest cover.

Correct Answer: False

Solution:

The Green Revolution was initially confined to irrigated areas, not rainfed areas, as it required assured supply of soil moisture through irrigation.

Correct Answer: True

Solution:

Southern states like Maharashtra, Karnataka, Tamil Nadu, and Andhra Pradesh have higher sugarcane yields compared to northern India.

Correct Answer: False

Solution:

Barren and wastelands, such as hilly terrains and deserts, are generally not suitable for cultivation with the current technology.

Correct Answer: False

Solution:

The area classified as forest in land revenue records is not necessarily equal to the actual forest cover. The former is the area identified and demarcated by the government for forest growth, which may increase without an actual increase in forest cover.

Correct Answer: True

Solution:

Despite occupying only 2.4% of the cropped area, India is a major producer of sugarcane, contributing about 19.7% of the world's production.

Correct Answer: True

Solution:

Sugarcane is not cultivated under dryland farming as it requires more water.

Correct Answer: False

Solution:

The Green Revolution initially benefited the irrigated areas of India, not the rainfed areas.

Correct Answer: False

Solution:

The introduction of HYVs required assured irrigation and other inputs like chemical fertilizers to be successful.

Correct Answer: False

Solution:

The area classified as forest is the land identified and demarcated by the government for forest growth, which may differ from the actual forest cover.

Correct Answer: True

Solution:

The area under non-agricultural uses has increased due to the expansion of urban and rural settlements, as well as the growth of industrial and service sectors.

Correct Answer: True

Solution:

The Green Revolution initially benefited only irrigated areas, leading to regional disparities in agricultural development until the technology spread to other parts of the country.
