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:

  1. Forests
    • Actual forest cover differs from area classified as forest.
    • Government demarcates area for forest growth.
  2. 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.

Multiple Choice Questions

A.

They are primarily used for industrial development.

B.

They provide essential resources like fodder and fuel to rural communities.

C.

They are mainly used for urban expansion.

D.

They are reserved for government use only.
Correct Answer: B

Solution:

Common Property Resources (CPRs) play a crucial role in rural economies by providing essential resources like fodder and fuel, which are vital for the livelihood of landless and marginal farmers.

Chapter Concept:

Economic and Demographic Influences on Land Use

A.

Wetland farming

B.

Dryland farming

C.

Irrigated farming

D.

Aquaculture
Correct Answer: B

Solution:

Dryland farming is practiced in areas with less than 75 cm of annual rainfall, focusing on drought-resistant crops.

Chapter Concept:

Climatic Influence on Agriculture

A.

It decreases the pressure on agricultural land.

B.

It leads to an increase in land under non-agricultural uses.

C.

It results in more land being left fallow.

D.

It reduces the need for land reclamation.
Correct Answer: B

Solution:

Economic growth, particularly the expansion of secondary and tertiary sectors, leads to an increase in land under non-agricultural uses.

Chapter Concept:

Economic and Demographic Influences on Land Use

A.

Cultivating water-intensive crops like rice and sugarcane.

B.

Implementing rainwater harvesting and growing drought-resistant crops.

C.

Relying solely on rainfed agriculture without any supplementary irrigation.

D.

Using excessive chemical fertilizers to boost crop yield.
Correct Answer: B

Solution:

In semi-arid regions, implementing rainwater harvesting and growing drought-resistant crops like ragi and bajra is essential for sustainable agriculture. This approach helps in conserving soil moisture and ensures crop survival during dry spells.

Chapter Concept:

Agricultural Land Use and Cropping Patterns

A.

Rice

B.

Wheat

C.

Cotton

D.

Jowar
Correct Answer: B

Solution:

Wheat is a major crop grown during the rabi season, which begins with the onset of winter in October-November.

Chapter Concept:

Agricultural Land Use and Cropping Patterns

A.

Increased regional disparities in agricultural development

B.

Decreased use of chemical fertilizers

C.

Reduced need for irrigation

D.

Decline in foodgrain production
Correct Answer: A

Solution:

The Green Revolution led to increased regional disparities in agricultural development as it was initially confined to irrigated areas.

Chapter Concept:

Green Revolution and Agricultural Development

A.

It was evenly distributed across all regions.

B.

It was concentrated in rainfed areas.

C.

It was confined to irrigated areas.

D.

It was focused on non-agricultural uses.
Correct Answer: C

Solution:

The Green Revolution was initially confined to irrigated areas, leading to regional disparities.

Chapter Concept:

Green Revolution and Agricultural Development

A.

Increase in agricultural productivity

B.

Expansion of wastelands

C.

Reduction in cultivable land

D.

Increase in forest cover
Correct Answer: C

Solution:

The increase in land under non-agricultural uses in India leads to a reduction in cultivable land as more land is used for urban and industrial development.

Chapter Concept:

Economic and Demographic Influences on Land Use

A.

It increases the area under forests.

B.

It leads to a decrease in barren and wasteland.

C.

It results in a shift of land from agricultural uses to non-agricultural uses.

D.

It increases the net area sown.
Correct Answer: C

Solution:

The growth of secondary and tertiary sectors usually results in a gradual shift of land from agricultural uses to non-agricultural uses, especially around urban areas.

Chapter Concept:

Land Use Categories and Changes in India

A.

Increased afforestation efforts.

B.

Growth in secondary and tertiary sectors.

C.

Improved agricultural productivity.

D.

Expansion of permanent pastures.
Correct Answer: B

Solution:

The increase in land put to non-agricultural uses is primarily driven by the growth in secondary and tertiary sectors, which demand more land for infrastructure, industries, and urban settlements.

True or False

Correct Answer: False

Solution:

In Punjab and Haryana, the cultivation of rice is primarily irrigated, not rainfed.

Chapter Concept :

Agricultural Land Use and Cropping Patterns

Correct Answer: True

Solution:

The text states that the increase in land under non-agricultural uses is due to the changing structure of the Indian economy, which increasingly depends on industrial and services sectors, leading to the expansion of related infrastructural facilities.

Chapter Concept :

Economic and Demographic Influences on Land Use

Correct Answer: True

Solution:

CPRs are defined as community's natural resources, where every member has the right of access and usage with specified obligations, without anybody having property rights over them.

Chapter Concept :

Common Property Resources and Land Ownership

Correct Answer: False

Solution:

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

Chapter Concept :

Economic and Demographic Influences on Land Use

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 Eastern and Central parts of India.

Chapter Concept :

Green Revolution and Agricultural Development

Correct Answer: True

Solution:

The National Mission for Sustainable Agriculture focuses on making agriculture more productive, sustainable, remunerative, and climate-resilient by promoting location-specific integrated/composite farming systems.

Chapter Concept :

Sustainable Agricultural Practices

Correct Answer: False

Solution:

The increase in the area under forests is mainly due to the increase in the demarcated area allocated for forest growth, not an actual increase in forest cover.

Chapter Concept :

Challenges in Indian Agriculture

Correct Answer: False

Solution:

The increase in net area sown is a recent phenomenon due to the use of culturable wasteland for agricultural purposes, not primarily due to the expansion of non-agricultural uses.

Chapter Concept :

Agricultural Land Use and Cropping Patterns

Correct Answer: True

Solution:

Dryland farming is largely confined to regions with annual rainfall less than 75 cm, where hardy and drought-resistant crops are grown.

Chapter Concept :

Climatic Influence on Agriculture

Correct Answer: False

Solution:

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