Land Use Categories
ExplanationLand Use Categories
Land is a vital natural resource that supports various human activities such as agriculture, habitation, industry, and recreation. The land around us is utilized in different ways depending on its suitability and human needs. The classification of land use helps in understanding how land is distributed for various purposes and is maintained by the land revenue department. It is important to distinguish between 'reporting area' which is based on land revenue records and 'geographical area' which is measured by the Survey of India. The reporting area may vary due to administrative changes or land use changes, whereas the geographical area remains fixed. The land-use categories as per land revenue records include: (i) Forests: This category refers to land demarcated by the government for forest growth. It is crucial to note that the area classified as forest may not always correspond to the actual forest cover, as the latter refers to the area under actual tree cover. The forest category in land records is based on government notifications and demarcations. (ii) Barren and Wastelands: These lands include barren hilly terrains, deserts, ravines, and other lands that are generally unsuitable for cultivation with current technology. (iii) Land put to Non-agricultural Uses: This includes land occupied by settlements (both rural and urban), infrastructure such as roads and canals, industries, shops, and other non-agricultural activities. Growth in secondary and tertiary sectors leads to an increase in this category. (iv) Area under Permanent Pastures and Grazing Lands: Mostly owned by village panchayats or government, these lands serve as grazing grounds for livestock. A small portion may be privately owned. Panchayat-owned lands are considered Common Property Resources (CPRs). (v) Area under Miscellaneous Tree Crops and Groves: This includes orchards and fruit tree plantations, mostly privately owned and not included in net sown area. (vi) Culturable Wasteland: Land left fallow or uncultivated for more than five years but can be reclaimed for cultivation through reclamation practices. (vii) Current Fallow: Land left uncultivated for one agricultural year or less, a cultural practice to restore soil fertility naturally. (viii) Fallow other than Current Fallow: Cultivable land left uncultivated for more than one year but less than five years. (ix) Net Area Sown: The actual physical area on which crops are sown and harvested during an agricultural year. Understanding these categories is essential for planning and managing land resources effectively.
- Land use records are maintained by the land revenue department and differ from fixed geographical area measured by Survey of India.
- Forests category includes government-demarcated forest land, not necessarily actual forest cover.
- Barren and wastelands are lands unsuitable for cultivation with current technology.
- Non-agricultural land includes settlements, infrastructure, industries, and shops.
- Permanent pastures and grazing lands are mostly community-owned and classified as Common Property Resources.
- Culturable wasteland and fallow lands represent cultivable land left uncultivated for varying periods.
- 📌 Reporting Area: Land area recorded in land revenue records, subject to change based on administrative updates.
- 📌 Geographical Area: Fixed land area measured by the Survey of India.
- 📌 Net Area Sown: Land area on which crops are sown and harvested in an agricultural year.
Land-use Changes in India
ExplanationLand-use Changes in India
Land use in India has undergone significant changes over time, influenced by economic growth, population increase, technological advancement, and changing economic activities. Although land is a fixed natural resource in terms of area, its use changes dynamically with economic development. Three main types of changes affect land use: (i) Growth in the size of the economy: As population and income levels rise, and technology advances, the demand for land increases. Marginal lands previously unused may come under cultivation or other uses. (ii) Change in economic composition: The secondary (manufacturing) and tertiary (services) sectors typically grow faster than the primary (agriculture) sector in developing countries like India. This leads to a shift of land from agricultural to non-agricultural uses, especially near urban areas where agricultural land is converted for building and infrastructure. (iii) Continued pressure on agricultural land: Despite a decline in agriculture's share in GDP, the pressure on agricultural land remains due to: (a) Slow decline in the population dependent on agriculture compared to the sector's GDP share decline. (b) Increasing population that agriculture must feed. The chapter presents data comparing land use between 1950-51 and 2019-20, showing: - Increase in forest area (due to demarcation, not necessarily actual forest cover), non-agricultural uses (due to urbanization and infrastructure), permanent pastures and grazing lands, current fallow lands, and net area sown (recently due to reclamation of culturable waste land). - Decline in barren and wastelands, culturable wasteland, area under tree crops and groves, and fallow other than current fallow lands. The increase in non-agricultural land is the most significant, reflecting India's economic transformation. The decline in wastelands and culturable wastelands is due to increased land pressure for agriculture and other uses. The decline in tree crops and groves is attributed to agricultural land pressure. Understanding these changes helps in planning sustainable land use and addressing challenges related to urbanization, agriculture, and environmental conservation.
- Land use changes are driven by economic growth, population increase, and changing economic activities.
- Non-agricultural land use has increased significantly due to urbanization and infrastructure expansion.
- Forest area increase reflects government demarcation rather than actual forest cover increase.
- Decline in wastelands and culturable wastelands due to increased land use pressure.
- Net sown area has increased recently due to reclamation of culturable waste land.
- Agricultural land is under continued pressure despite a decline in agriculture's GDP share.
- 📌 Economic Composition: The relative contribution of primary, secondary, and tertiary sectors to the economy.
- 📌 Non-agricultural Uses: Land used for settlements, infrastructure, and industries.
- 📌 Culturable Wasteland: Land left uncultivated for more than five years but can be reclaimed.
Common Property Resources
ExplanationCommon Property Resources
Land ownership in India can be broadly classified into private land and Common Property Resources (CPRs). Private land is owned by individuals or groups, whereas CPRs are owned by the state or community and meant for collective use. CPRs include com

Includes NCERT exercise questions with answers
Q1.What changes have you noticed in agricultural sector and cropping – pattern? Discuss in the class.
Answer:
The agricultural sector in India has witnessed several changes over the years. These include the introduction of modern agricultural equipment such as the Roto Till Drill, increased dependence on irrigation though still limited to about 33% of cultivated land, and a shift towards more commercialized farming in irrigated areas. Cropping patterns have also changed with a move towards less water-intensive crops like pulses and oilseeds, as suggested by recent initiatives promoting Green Revolution 2.0. Fragmentation of landholdings and small farm sizes continue to affect productivity. The discussion should include these points and any regional variations observed.
Explanation:
The question asks for observations and discussion based on the text. Key points include dependence on erratic monsoon, low productivity, financial constraints, land reforms, fragmentation of landholdings, lack of commercialization, and recent policy suggestions for promoting less water-intensive crops. These factors collectively influence changes in agriculture and cropping patterns.

(a) Fallow land (b) Marginal land (c) Net Area Sown (d) Culturable Wasteland (ii) What one of the following is the main reason due to which share of forest has shown an increase in the last forty years? (a) Extensive and efficient efforts of afforestation (b) Increase in community forest land (c) Increase in notified area allocated for forest growth (d) Better peoples' participation in managing forest area. (iii) Which one of the following is the main form of degradation in irrigated areas? (a) Gully erosion (b) Wind erosion (c) Salinisation of soils (d) Siltation of land (iv) Which one of the following crops is not cultivated under dryland farming? (a) Ragi (b) Jowar (c) Groundnut (d) Sugarcane (v) In which of the following group of countries of the world, HYVs of wheat and rice were developed? (a) Japan and Australia (b) U.S.A. and Japan (c) Mexico and Philippines (d) Mexico and Singapore
Answer:
Answers: (i) (b) Marginal land Explanation: Marginal land is not a land-use category but a classification based on productivity. The main land-use categories include Fallow land, Net Area Sown, and Culturable Wasteland. (ii) (a) Extensive and efficient efforts of afforestation Explanation: The increase in forest area over the last forty years is mainly due to extensive afforestation efforts by the government and other agencies. (iii) (c) Salinisation of soils Explanation: In irrigated areas, salinisation is the main form of land degradation caused by improper irrigation practices leading to salt accumulation. (iv) (d) Sugarcane Explanation: Sugarcane is a water-intensive crop and is not cultivated under dryland farming which relies on rainfall. (v) (c) Mexico and Philippines Explanation: High Yielding Varieties (HYVs) of wheat and rice were developed in Mexico and Philippines as part of the Green Revolution.
Explanation:
Step-by-step explanation: (i) Land-use categories classify land based on its use such as cultivated, fallow, forest, wasteland etc. Marginal land refers to land with low productivity and is not a category. (ii) Forest area increase is due to afforestation programs, not just community or notified areas. (iii) Irrigated lands often suffer from salinisation due to waterlogging and poor drainage. (iv) Dryland farming depends on rainfall; sugarcane requires irrigation. (v) HYVs were developed in Mexico (wheat) and Philippines (rice) during the Green Revolution.
Q3.2. Answer the following questions in about 30 words. (i) Differentiate between barren and wasteland and culturable wasteland. (ii) How would you distinguish between net sown area and gross cropped area? (iii) Why is the strategy of increasing cropping intensity important in a country like India? (iv) How do you measure total cultivable land? (v) What is the difference between dryland and wetland farming?
Answer:
Answers: (i) Barren and wasteland refers to land which is not suitable for cultivation due to natural or man-made reasons. Culturable wasteland is land which is currently not cultivated but can be brought under cultivation with reasonable effort. (ii) Net sown area is the actual area sown with crops during a year. Gross cropped area is the total area sown including multiple cropping, i.e., net sown area plus area sown more than once. (iii) Increasing cropping intensity means growing more than one crop on the same land in a year. This is important in India to increase food production without expanding cultivated area. (iv) Total cultivable land is measured by adding net sown area, current fallow land, other fallow land, and culturable wasteland. (v) Dryland farming depends on rainfall and is practiced in areas with low rainfall. Wetland farming depends on irrigation or natural water availability and is practiced in areas with adequate water supply.
Explanation:
Step-by-step explanation: (i) Barren/wasteland is uncultivable; culturable wasteland can be cultivated with effort. (ii) Net sown area counts each piece of land once; gross cropped area counts multiple crops on same land. (iii) Cropping intensity increases production without needing more land. (iv) Total cultivable land includes all land that can be used for cultivation. (v) Dryland farming relies on rainfall; wetland farming relies on irrigation.
Q4.3. Answer the following questions in about 150 words. (i) What are the different types of environmental problems of land resources in India? (ii) What are the important strategies for agricultural development followed in the post-independence period in India?
Answer:
Answers: (i) Environmental problems of land resources in India include land degradation due to soil erosion (water and wind), deforestation, salinisation and alkalisation of soils, waterlogging, loss of soil fertility, and desertification. These problems reduce the productive capacity of land and affect agricultural output. (ii) Important strategies for agricultural development in post-independence India include the Green Revolution with introduction of High Yielding Varieties (HYVs) of seeds, expansion of irrigation facilities, use of fertilizers and pesticides, land reforms, development of agricultural infrastructure, and promotion of dryland farming techniques. These strategies aimed to increase food production and achieve self-sufficiency.
Explanation:
Step-by-step explanation: (i) Identify major environmental issues affecting land: erosion, salinity, waterlogging, deforestation. (ii) Post-independence strategies include technological innovations (HYVs), irrigation expansion, chemical inputs, land reforms, and infrastructure development to boost agriculture.
Q5.Which department in India is responsible for maintaining land-use records?
Answer:
Land Revenue Department
Explanation:
The Land Revenue Department maintains land-use records in India. These records categorize land use for administrative and planning purposes. The Survey of India measures geographical area but does not maintain land-use records.
Q6.What is the difference between 'area classified as forest' and 'actual forest cover' in India?
Answer:
Area classified as forest is the land demarcated by the government for forest growth, whereas actual forest cover refers to the land area under actual tree cover.
Explanation:
The area classified as forest is based on government notifications and demarcations and may not correspond to the actual forest cover. Actual forest cover is the physical area covered by trees. Thus, the forest category in land records may increase without an increase in actual forest cover.
Q7.Identify the land-use category that includes barren hilly terrains, deserts, and ravines, which are generally unsuitable for cultivation with current technology.
Answer:
Barren and Wastelands
Explanation:
Barren and wastelands include areas such as barren hilly terrains, deserts, and ravines. These lands are generally unsuitable for cultivation with the available technology, and thus are classified separately in land-use records.
Q8.Which land-use category includes land under settlements, infrastructure, industries, and shops?
Answer:
Land put to Non-agricultural Uses
Explanation:
Land put to non-agricultural uses includes land occupied by rural and urban settlements, infrastructure like roads and canals, industries, and shops. This category grows with expansion in secondary and tertiary economic activities.
