5. Land, Resources and Agriculture

Competency Based Questions:

1. A farmer in Rajasthan wants to shift from cultivating pearl millet to growing vegetables using tube-well irrigation. Which land-use principle should guide his decision to ensure sustainable use of land resources?

a) Use land according to its capability and water availability

b) Maximize use of chemical fertilizers to increase yield

c) Bring as much land as possible under cultivation

d) Convert all common grazing land into private farms

Ans: c) Bring as much land as possible under cultivation

It captures the basic geographic principle that land should be used according to its capability and the available water resources.

In physical geography and resource planning, each parcel of land has a certain capability determined by relief, soil, climate, and water. For sustainable agriculture, farmers must match crop choice and intensity of cultivation with these natural limits. In Rajasthan, pearl millet is widely grown because it is drought resistant and can survive in sandy soils with low moisture. Shifting to vegetables, which are often water demanding, requires assessing groundwater recharge rates, irrigation technology, and potential environmental impacts such as salinization or depletion of aquifers. The principle “use land according to its capability and water availability” prevents over-exploitation, maintains soil fertility, and helps ensure that agriculture remains viable for future generations.

2. In a coastal district, paddy fields are increasingly being converted into housing colonies for urban expansion. Which long-term consequence is most likely if such conversion continues unchecked?

a) Increase in agricultural biodiversity

b) Improved groundwater recharge

c) Loss of food security and ecological balance

d) Enhanced soil fertility in remaining fields

Ans: c) Loss of food security and ecological balance

Continuous conversion of paddy fields into housing colonies is likely to reduce food production and disturb ecological processes.

Land is a finite resource, and expanding urban land uses often encroach on fertile agricultural land, particularly around cities. Paddy fields contribute significantly to local food grain supply and support various wetland ecosystems. Their loss means fewer areas available for cultivation of rice and related crops, thereby affecting food security, especially for poorer sections who rely on local supply. Ecologically, the replacement of permeable, biologically active soils with concrete surfaces disrupts groundwater recharge, increases surface runoff, worsens flood risks, and eliminates habitats for many aquatic and semi-aquatic species. Over time, this can create imbalances in hydrological cycles and local climate, illustrating why unregulated land conversion is a serious concern.

3. A farmer in the Ganga plain follows cereal–legume crop rotation on the same plot. How does this practice help in sustainable management of agricultural land?

a) It permanently eliminates all weeds from the field

b) It increases dependence on chemical fertilizers each year

c) It ensures that the soil remains constantly waterlogged

d) It helps maintain soil fertility and reduces pest build-up

Ans: d) It helps maintain soil fertility and reduces pest build-up

Cereal–legume rotation is a classic example of how cropping patterns can help conserve soil fertility and manage pests more sustainably.

Legumes have symbiotic bacteria in their root nodules that fix atmospheric nitrogen, enriching the soil naturally. When a cereal such as wheat or rice is grown after a legume, it benefits from the extra nitrogen, which supports better yields without heavy fertilizer use. Rotation also breaks the continuous food supply that pests and disease organisms might otherwise enjoy if the same crop were planted repeatedly. This reduces pest build-up, minimizes the use of chemical pesticides, and maintains ecological balance in the field. Thus, crop rotation is a practical tool for managing land resources sustainably while supporting farmers’ livelihoods.

4. Which of the following best illustrates the concept of land degradation in Indian agriculture?

a) Adopting drip irrigation in a semi-arid region

b) Expansion of contour ploughing in hilly areas

c) Increasing tree cover on community pastures

d) Formation of gullies due to unchecked soil erosion

Ans: d) Formation of gullies due to unchecked soil erosion

Formation of gullies is a visible and serious manifestation of land degradation in many parts of India.

Gullies develop when water flows with enough speed and volume to cut into the soil, particularly where vegetation cover is poor and slopes are vulnerable. Over time, small rills deepen into gullies, and networks of gullies can transform once-productive land into ravines. This process removes the nutrient-rich topsoil layer, exposes subsoil or rock, and makes mechanised farming difficult or impossible. E.g. Chambal ravines. It reduces agricultural productivity, increases sediment load in rivers, and often requires costly reclamation measures like afforestation, check dams, and contour bunding. Therefore, gully formation is a textbook example of land degradation linked to improper land and water management.

5. A village in Maharashtra decides to develop cooperative farming on fragmented small holdings. What is the main advantage of this approach for effective land use?

a) Land will remain fallow most of the time

b) Small plots can be pooled to use modern inputs and technology

c) It completely eliminates the need for institutional credit

d)  Each farmer can cultivate only subsistence crops

Ans: b) Small plots can be pooled to use modern inputs and technology

The core objective of cooperative farming is to overcome the disadvantages of fragmented holdings by pooling resources.

When small, scattered plots are cultivated separately, farmers cannot easily adopt tractors, harvesters, or advanced irrigation because each plot is too small and dispersed. By forming a cooperative, farmers can treat their combined land as one large operational unit, which makes mechanization viable and reduces per-unit costs of inputs. They can also negotiate better prices for seeds, fertilizers, and outputs due to collective bargaining. This approach improves the overall productivity of land, helps in adopting improved crop varieties, and can support diversification into higher-value crops, making land use more efficient and economically beneficial.

6. An agriculturist is practicing intensive subsistence farming with rice as the main crop in a densely populated region of eastern India. Which characteristic most accurately describes this type of agriculture?

a) Large holdings, high mechanization, and surplus export of crops

b) Small holdings, use of family labor, and high cropping intensity

c) Extensive use of pastures with low labor input

d) Dependence mainly on plantation crops like tea and rubber

Ans: b) Small holdings, use of family labor, and high cropping intensity

Intensive subsistence farming with rice in eastern India typically involves small landholdings, high use of family labor, and multiple crops grown on the same land each year.

This system is common in states such as West Bengal, Bihar, and parts of Odisha and Assam. Farmers rely heavily on manual labor from family members because they cannot afford large machines and because small, irregular plots are not suited to heavy mechanization. With fertile alluvial soils and favorable monsoon rainfall, they often practice multiple cropping, growing rice in the kharif season and another crop like wheat, pulses, or vegetables in the rabi or pre-kharif season. Inputs like manure and some fertilizers are used, but the overall focus remains on securing subsistence food supply. Land is used very intensively due to high population pressure, which is why this system is called intensive subsistence agriculture.

7. Which situation best reflects the idea of “disguised unemployment” in Indian agriculture?

a) Five family members working on a small plot where output would remain the same even if two stopped working

b) A farmer taking a seasonal loan to buy fertilizers

c) A farm worker using improved seeds to increase yield per hectare

d) A single worker managing a large mechanized wheat farm efficiently

Ans: a) Five family members working on a small plot where output would remain the same even if two stopped working

When several family members work on a very small farm but removing some of them does not reduce total output, it indicates disguised unemployment.

Disguised unemployment is described as a situation where the marginal productivity of some workers is effectively zero. They are formally employed, but their contribution to production is negligible or nil. In many rural parts of India, small farms cannot productively absorb all available family labor, so additional workers simply share the same amount of work without increasing output. This hides true unemployment levels and keeps agricultural productivity low. Recognizing such disguised unemployment is important for planning policies that create non-farm jobs, promote agro-based industries, and encourage education and skill development so that surplus labor can move into more productive sectors.

8. In which of the following situations is shifting cultivation most likely to lead to serious land degradation?

a) When only small sections of dense forest are cleared and left undisturbed for decades

b) When long fallow periods allow forest to regenerate between cropping cycles

c) When fallow periods become very short due to high population pressure

d) When shifting cultivation is practiced with strict community regulations on land use

Ans: c) When fallow periods become very short due to high population pressure

Shortening of fallow periods due to high population density is a major reason why shifting cultivation can become environmentally damaging.

Shifting cultivation or jhum, traditionally relied on long cycles of cultivation followed by extended fallow periods. This allowed secondary forest to regrow, stabilizing the soil, restoring nutrients through natural processes, and maintaining biodiversity. As population pressure rises, communities may have to return to the same plot more quickly, sometimes after only a few years. The vegetation has not fully recovered, the soil remains weak, and repeated burning and cultivation remove remaining nutrients. The exposed soil is then easily eroded by rain, leading to loss of fertile topsoil and formation of degraded wastelands. This process demonstrates how a once-balanced land-use system can become unsustainable when its ecological conditions, such as adequate fallow duration, are not maintained.

9. A farmer in Punjab decides to pump large amounts of groundwater to grow water-intensive rice during the dry season. Which potential impact on land resources is most concerning from a sustainability perspective?

a) Complete elimination of all salinity-related problems

b) Gradual fall in groundwater table leading to long-term stress on land and agriculture

c) Permanent increase in soil organic matter

d) Immediate and permanent improvement in soil structure

Ans: b) Gradual fall in groundwater table leading to long-term stress on land and agriculture

Over-pumping groundwater for a water-intensive crop like rice can cause a continuous decline in the groundwater table, putting long-term stress on both land and agriculture.

Punjab is cited as a region where the Green Revolution significantly increased food grain production but also led to overexploitation of groundwater. When extraction exceeds natural recharge, water levels fall, wells need to be deepened, and pumping costs rise. In extreme cases, aquifers may be depleted or contaminated. Land resources are affected because irrigation becomes less reliable and more expensive, and soils may suffer from changes in water and salt balance. If farmers continue cultivating highly water-demanding crops irrespective of the region’s water availability, the overall agricultural system becomes unsustainable, threatening future productivity and the livelihoods that depend on it.

10. Which agricultural practice directly contributes to conservation of soil moisture and reduction of run-off on sloping lands?

a) Removing all vegetation cover before the onset of monsoon

b) Growing monoculture crops on steep slopes without any bunds

c) Practicing contour ploughing following the natural shape of the slope

d) Allowing rainwater to flow straight down the slope through open channels

Ans: c) Practicing contour ploughing following the natural shape of the slope

This option is correct. Contour ploughing is specifically designed to conserve soil and water on sloping land by following the natural contours.

When ploughing follows the contour lines, the resulting ridges and furrows act as small barriers that interrupt the direct downhill flow of rainwater. This reduces the speed of run-off, encourages infiltration into the soil, and helps maintain soil moisture, which is crucial for crop growth in rainfed conditions. Over time, contour ploughing can significantly decrease soil erosion, preserve the fertile topsoil layer and maintain the productivity of the land. In Indian agriculture, especially in hilly states and undulating plateaus, combining contour ploughing with terracing, strip cropping, and vegetative barriers forms a comprehensive strategy for sustainable land management and erosion control.

11. In the context of Indian agriculture, which scenario best demonstrates diversification as a strategy for sustainable rural livelihoods?

a) A farmer grows only wheat on all his land year after year

b) A farmer stops agriculture and migrates permanently to a city for non-farm work

c) A village shifts entirely from agriculture to mining

d) A group of farmers combines crop cultivation with dairy farming and poultry

Ans: d) A group of farmers combines crop cultivation with dairy farming and poultry

Combining crop cultivation with dairy farming and poultry is a classic form of agricultural diversification that strengthens rural livelihoods.

Diversification involves broadening the range of economic activities within the rural economy rather than relying on a single crop or occupation. When farmers keep dairy animals and poultry in addition to growing crops, they gain multiple streams of income throughout the year. Milk and eggs can be sold daily or weekly, providing regular cash flow, while crops bring seasonal income. Moreover, crop residues can feed cattle and poultry, and their manure can be used to maintain soil fertility, creating a nutrient cycle that supports sustainable land use. This integrated approach reduces risk from crop failure due to drought or pests and helps rural households cope better with market volatility, aligning well with the concept of sustainable development in agriculture.

12. Which statement best explains why land resources in India require careful planning and management?

a) India has so much unused land that planning is unnecessary

b) Land is used only for agriculture and not for any other purposes

c) Land is an inexhaustible resource that can regenerate quickly on its own

d) Land area is fixed but demands on it for agriculture, industry, and habitation are increasing

Ans: d) Land area is fixed but demands on it for agriculture, industry, and habitation are increasing

The key reason for careful planning and management of land resources in India is that land area is fixed while demands on it continue to grow.

India has to accommodate agriculture, forests, industries, transport networks, housing, recreation, and conservation areas all within a limited geographical space. Population growth, urbanisation, and economic development intensify pressure on land, often resulting in deforestation, encroachment on fertile agricultural land, and expansion of wastelands due to degradation. Land-use planning aims to balance these competing demands by identifying suitable areas for different activities, protecting fragile ecosystems like hill slopes and coastal zones, and promoting sustainable practices such as soil conservation, watershed management, and afforestation. Effective planning ensures that land remains productive, environmentally stable, and capable of supporting both present and future generations.

Subjective Questions:

1. Summarize various uses of land and describes the land- use categories as maintained in the Land Revenue Records.

Ans: Land in India serves multiple essential uses, including agriculture, forestry, settlements, infrastructure, and grazing, reflecting its role as a finite resource under increasing pressure from population growth and urbanization. Proper categorization helps in planning, monitoring changes, and sustainable management.

Land Use Categories

The Land Revenue Records maintain nine primary land-use categories, as defined by the Survey of India and state revenue departments for reporting and classification.

• Forests: Areas officially designated for forest growth by the government; actual forest cover may differ due to policy changes rather than ecological shifts.
• Barren and Wastelands: Uncultivable land like deserts, rocky terrains, or ravines, unsuitable for farming with current technology.
• Land put to Non-agricultural Uses: Includes settlements, roads, industries, canals, and shops, expanding due to urbanization and infrastructure needs.
• Permanent Pastures and Grazing Lands: Mostly village panchayat or government-owned common property resources for livestock grazing.
• Miscellaneous Tree Crops and Groves: Private orchards, fruit trees, and plantations, excluded from net sown area.
• Culturable Wasteland: Land left uncultivated for over five years but potential for reclamation and farming.
• Current Fallow: Recently cultivated land left idle for one season to regain fertility, typically during crop rotation.
• Fallow other than Current Fallow: Long-term fallow land uncultivated for 1-5 years.
• Net Area Sown: Land sown at least once a year, excluding current fallows; key indicator of agricultural land use.

Net sown area has remained stable around 46% of total reporting area, while non-agricultural uses and forests show increases due to development and afforestation efforts. These categories reveal challenges like shrinking cultivable land amid urban expansion.

2. Analyze types of changes and graphs showing changes in shares of land- use categories in India.

Ans: Land use in India has undergone significant shifts from 1950-51 to 2019-20, driven by population growth, economic diversification, and policy interventions, with four categories increasing and four decreasing in share.

Types of Changes

Changes are categorized into increases and decreases based on percentage share of reporting area, reflecting pressures like urbanization and agricultural intensification.

Increases:

• Area under non-agricultural uses (highest growth due to infrastructure, settlements, and industrial expansion).
• Forests (afforestation policies offsetting some losses).​
• Current fallow lands (crop rotation needs).​
• Net sown area (slight rise from marginal land cultivation).​

Decreases:

• Barren and wasteland (reclaimed for use).​
• Culturable wasteland (brought under cultivation).​
• Permanent pastures and grazing lands (encroached for farming).
• Fallow lands other than current (converted to productive use).​

Graphical Representation

NCERT depicts these trends in a line or bar graph titled “Changes in Shares of Land-use Categories in India: 1950–51 and 2019–20,” showing percentage shares; non-agricultural use rises sharply, while pastures decline notably.

Recent data (2022-23) from official reports mirrors this, with graphs illustrating stable net sown area (46%) amid rising non-agri uses (8-9%).

3. Explain the concept of common property resources and its importance for women in India.

Ans: Common property resources (CPRs) refer to natural assets like pastures, forests, ponds, and wastelands that are collectively owned, managed, or accessible to a defined community, such as villagers, without exclusive individual rights.

Key Features

CPRs operate under shared norms where group members have joint rights to use and duties to maintain resources, often governed by customary rules rather than formal titles; examples include village grazing lands, sacred groves, and threshing grounds.

In India, CPRs constitute about 15% of the geographical area (roughly 0.31 ha per household), supporting rural livelihoods through fodder, fuelwood, and water, but they face degradation from overexploitation and encroachment.

Importance for Women

These resources are vital for rural women, who bear primary responsibility for household fuel, fodder, and water collection, often spending significant time daily on CPR-dependent tasks; their decline forces longer travel, drudgery, and reduced time for education or income activities.

Women’s dependence highlights gender inequities, as men typically control decisions on CPR management, yet community institutions like panchayats can empower female participation for sustainable use.​

4. Analyze why there has been a greater decline of cultivated land, despite a corresponding decline of cultivable wasteland.

Ans: Cultivable land (net sown area + fallows + culturable wasteland) has seen a marginal decline as a percentage of total reporting area, even though culturable wasteland decreased due to reclamation; however, cultivated land (primarily net sown area) has declined more sharply due to conversion to non-agricultural purposes.

Key Reasons for Decline

The greater drop in cultivated land stems from intense pressure on agricultural areas, outpacing wasteland reclamation efforts.

• Urbanization and Infrastructure: Prime agricultural land is diverted for cities, roads, industries, and settlements, reducing net sown area faster than wastelands are converted.
• Population Pressure: Rising demand shifts land from cultivation to non-agri uses; encroachment on wastelands for farming is insufficient to offset losses.
• Land Degradation: Soil erosion, nutrient depletion, and water scarcity render cultivated land unproductive, leading to abandonment despite some wasteland gains.
• Fragmentation and Uneconomic Holdings: Inheritance laws fragment farms into small plots, making modern farming unviable and prompting sales for development.​

Implications

This paradox highlights unsustainable land management, with official data (1950-51 to 2019-20) showing non-agricultural uses rising while total cultivable stock shrinks marginally. Reclamation alone cannot counter urban expansion’s impact on fertile cropland.

5. Determine strategies to evolve and adopt land- saving technologies for bringing in additional land under net sown area and for increasing cropping intensity in India.

Ans: Land-saving technologies focus on maximizing productivity from existing farmland without expanding net sown area, addressing India’s constraints like population pressure and land scarcity. These strategies enhance efficiency through precision inputs, multiple cropping, and resource optimization.

Bringing Additional Land under Net Sown Area

Target culturable wastelands, current fallows, and degraded lands for reclamation using sustainable methods to boost cultivable stock without diverting prime areas.

• Adopt soil conservation techniques like contour bunding, terracing, and afforestation on ravines or eroded slopes to reclaim 13-15 million hectares of culturable wasteland.
• Promote watershed management with check dams and water harvesting to make arid/semi-arid lands viable for rainfed farming.
• Use bio-reclamation via leguminous crops and organic manure to restore soil fertility on fallows, increasing net sown area marginally to 47-48%.​

Increasing Cropping Intensity

Cropping intensity (gross cropped area/net sown area × 100) can rise from current 144% to over 160% by enabling multiple crops per year on the same land.​

• Implement micro-irrigation (drip/sprinkler) under (Pradhan Mantri Krishi Sinchayee Yojana) PMKSY to save 30-50% water, allowing rabi/kharif extensions in water-scarce regions like Rajasthan and Gujarat.
• Introduce short-duration, high-yielding varieties (HYVs) and hybrids for rice-wheat/potato systems, fitting three crops annually in Indo-Gangetic plains.
• Leverage precision farming with soil nutrient sensors, GPS-guided variable-rate fertilizers, and AI advisories to cut waste by 20%, boosting yields 15-30%.

6. Describe three distinct crop seasons and major crops sown in the northern and interior parts of India.

Ans: India’s northern and interior regions feature three distinct cropping seasons aligned with monsoon, winter, and summer patterns, enabling diverse agricultural output.

Kharif Season

Kharif crops are sown in June-July with monsoon onset and harvested in September-October, relying on rainfall for growth in states like Uttar Pradesh, Madhya Pradesh, and Rajasthan.

Major crops include rice (paddy), maize, bajra (pearl millet), jowar (sorghum), cotton, groundnut, soybean, tur (pigeon pea), moong, and urad.

Rabi Season

Rabi crops are sown in October-November after monsoons and harvested in March-April, dependent on irrigation and cooler winters in Punjab, Haryana, Uttar Pradesh, Bihar, and Madhya Pradesh.

Key crops are wheat, barley, gram (chickpea), mustard, rapeseed, peas, lentils, and oats.

Zaid Season

Zaid crops fill the summer gap, sown in March-June and harvested by July before kharif, suited to irrigated areas in northern plains like Uttar Pradesh and Bihar.

Prominent crops include seasonal fruits (watermelon, muskmelon), vegetables (cucumber, gourd), pulses (moong), and fodder grasses.

7. Classify farming into two types based on the main source of moisture for crops.

Ans: Farming in India is classified into two main types based on the primary source of moisture for crops: irrigated farming and rainfed farming.​

Irrigated Farming

This type relies on artificial water supply through canals, wells, tube wells, tanks, or modern systems like drip and sprinklers, ensuring stable moisture regardless of rainfall variability.

It covers about 47% of cultivated area, supports higher cropping intensity (over 150%), and dominates in fertile regions like Punjab and Haryana, enabling protective (moisture assurance) or productive (yield maximization) objectives.​

Rainfed Farming

Also called dryland or barani farming, it depends entirely on natural monsoon rainfall (June-September), practiced on 53% of net sown area in rain-shadow zones like Deccan Plateau and central India.

Sub-types include dryland (low rainfall <75 cm, drought-resistant crops like millets) and wetland (adequate monsoon >100 cm for rice/paddy); it faces risks from erratic rains but promotes soil conservation.

8. Explain the importance of food grains for the Indian agricultural economy.

Ans: Food grains form the backbone of India’s agricultural economy, occupying about two-thirds of the gross cropped area and serving as the primary staple for over 1.4 billion people.

Economic Significance

These crops, including cereals like rice and wheat plus pulses, dominate both subsistence and commercial farming across regions, providing stable rural incomes, employment for 40-50% of the workforce, and raw materials for agro-industries such as milling, animal feed, and starch processing.

India’s production has risen to over 330 million tonnes annually (2023-24), achieving self-sufficiency from past deficits through Green Revolution technologies, MSP procurement by FCI, and schemes like NFSM, reducing import reliance and stabilizing prices.

Food Security Role

Food grains ensure national food security via (Public Distribution System) PDS buffer stocks, combat malnutrition by supplying 70-80% of caloric intake for the poor, and support exports while buffering against droughts or global shocks.

9. Summarize cereal, pulses, oilseed, fiber crops, sugarcane, tea and coffee production in India.

Ans: India’s agricultural economy relies heavily on diverse crops like cereals, pulses, oilseeds, fibers, sugarcane, tea, and coffee, which together occupy over 80% of the gross cropped area and drive food security, exports, and rural livelihoods.

Cereal Production

Cereals (rice, wheat, maize, millets, barley) dominate with record output exceeding 350 million tonnes in 2024-25, led by Uttar Pradesh (rice/wheat), West Bengal (rice), and Punjab (wheat); rice and wheat alone contribute 60% of foodgrains, supporting self-sufficiency via Green Revolution gains.

Pulses and Oilseeds

Pulses (gram, tur, moong, urad) production hovers around 25-28 million tonnes annually from Madhya Pradesh and Rajasthan, vital for protein and soil nitrogen fixation; oilseeds (groundnut, rapeseed, soybean) yield 40 million tonnes, with Gujarat and Rajasthan key addressing edible oil import gaps (60% dependency).

Fibre, Sugarcane, Tea, Coffee

Fibre crops like cotton (39 million bales, Maharashtra/Gujarat) and jute support textiles; sugarcane hits 475+ million tonnes (UP/Maharashtra) for sugar/ethanol; tea (1,400 million kg, Assam/West Bengal) and coffee (0.4 million tonnes, Karnataka/Kerala) are plantation exports, generating forex and employing millions.

10. Analyse the impact of the Intensive Agricultural District Programme (IADP), the Intensive Agricultural Area Programme (IAAP) and the Green Revolution on Indian agriculture.

Ans: The Intensive Agricultural District Programme (IADP, 1960), Intensive Agricultural Area Programme (IAAP, 1964), and Green Revolution (1965-70s) marked pivotal shifts from extensive to intensive farming in India, boosting productivity through targeted interventions.

IADP Impact

IADP, piloted in 7 high-potential districts (e.g., Thanjavur, Ludhiana), adopted a “package approach” with HYVs, fertilizers, irrigation, credit, and extension services, yielding 20-30% higher foodgrain output and demonstrating modern techniques’ viability.

It improved input markets and farmer adoption but was limited to irrigated wheat/rice areas, benefiting larger farmers and paving the way for replication.

IAAP Impact

As IADP’s expansion to 114 districts, IAAP scaled up HYV seeds and inputs across larger regions, increasing foodgrain production by 25-50% in targeted blocks and enhancing infrastructure like marketing and mechanization.

It addressed IADP’s narrow scope but faced equity issues, favouring progressive farmers in favourable agro-climatic zones.​

Green Revolution Impact

Building on IADP/IAAP, the GR introduced HYV seeds (wheat from Mexico, rice from IRRI), chemical inputs, and tube-well irrigation, tripling wheat (from 12 to 36 Mt) and rice yields in Punjab-Haryana-UP, achieving food self-sufficiency by 1970s.

Positive effects included averted famines, rural employment surge, and GDP contribution rise to 4%; negatives encompassed regional disparities (bypassing rainfed east/south), groundwater depletion, soil degradation, and inequality favouring big farmers.

11. Determine the causes and consequences of the growth of agricultural output and technology.

Ans: The growth of agricultural output and technology in India stems from institutional reforms, public investments, and innovations like HYVs and mechanization, driving productivity from Green Revolution onward.

Causes of Growth

Key drivers include expanded irrigation (from 18% to 48% net sown area), R&D investments yielding 10-12% TFP growth, government schemes (NFSM, PMKSY), and agtech adoption (drones, AI, precision farming) boosting yields 25-35%.

Digital platforms, FPOs, and agri-stack data enable input efficiency, while MSP and subsidies encourage tech uptake amid rising rural internet (50%+).​

Positive Consequences

Output surged to 350+ Mt foodgrains (2024-25), farmer incomes rose 25-35% in tech-adopting areas, employment grew via processing/value chains, and exports hit $50B+, enhancing food security and GDP share (18%).

Resource efficiency reduced input costs 15-20%, conserved water/soil, and diversified crops.​

Negative Consequences

Overuse caused groundwater depletion (30% blocks critical), soil degradation from imbalanced fertilizers, regional disparities (rainfed areas lag), farmer debt from high input costs, and biodiversity loss.

Equity gaps widened, with smallholders (<2 ha, 86% farmers) underserved by tech.​

12. Analyse the shortcomings of agriculture in India and their impact on food production and farmers.

Ans: Indian agriculture faces persistent structural, environmental, and economic shortcomings that constrain productivity, exacerbate farmer distress, and undermine food production stability.

Key Shortcomings

Challenges include small/marginal landholdings (86% of farmers with <2 ha), overdependence on erratic monsoons (50% unirrigated), low yields (e.g., rice 50% of global average), land degradation (30% affected), fragmented markets, high input costs, climate risks, and inadequate mechanization/tech adoption.

Soil nutrient imbalances from overuse of chemicals, groundwater depletion in 60% districts, and poor storage lead to 20-30% post-harvest losses.​

Impact on Food Production

These issues cap output growth at 2-3% annually despite potential, causing yield gaps (wheat 40% below global), vulnerability to droughts/floods (e.g., 2025 tur crop down 40%), and import reliance for pulses/oilseeds; climate projections warn of 20-47% drops in key crops by 2080 without resilience measures.

Food security remains fragile, with buffer stocks strained by weather shocks.​

Impact on Farmers

Low incomes (₹10,000-15,000/month average), debt traps from subsidies favouring inputs over outputs, suicides linked to crop failures/market crashes, migration from rainfed areas, and inequities widen rural-urban divides; smallholders miss tech benefits, perpetuating poverty cycles.

2. Answer the following questions in about 30 words:

(i) Differentiate between barren and wasteland and culturable wasteland.

Ans.

(ii) How would you distinguish between net sown area and gross cropped area?

Ans.

(iii) What is the difference between dry land and wetland farming?

Ans.

(iv) Why is the strategy of increasing cropping intensity important in a country like India?

Ans. The strategy of increasing crop intensity aims at increasing the productivity of a piece of land by increasing the number of times it is cultivated in a year. It aims at increasing the productivity of agriculture by increasing the productivity of already cultivated area. It is important for country like India where there is dearth of land so it is difficult to bring new pieces of land under cultivation to meet the ever increasing demand of rising population.

(v) How do you measure a total cultivable land?

Ans. Total cultivable land is the entire land which can be cultivated either in the current state or after reclaiming it through the available technologies. It is the sum of total culturable wasteland. Fallow other than current fallow and net sown area.

3. Answer the following questions in about 150 words:

(i) What are the different types of environmental problems of land resources in India?

Ans. Land resources in India are faced with multiple issues that lead to decline in their productivity. The causes are both environmental and related to malpractices. The main environmental issues confronting Indian resources are:

Dependence of erratic monsoon: Irrigation covers only about 33% of the cultivated area in India. The crop production in rest of the cultivated land directly depends on rainfall. Poor monsoon adversely affects the supply of canal water for irrigation. Rainfall in drought prone areas is too meagre and highly unreliable. Even the areas receiving high annual rainfall experience considerable fluctuations. This makes them vulnerable to both droughts and floods. Droughts and floods continue to be twin menace in India.

Low productivity: The yield of the crop in the country is low in comparison to the international level. Indian agriculture is also very low in comparison to international level. The vast rainfed areas of the country, particularly dry lands, which mostly grow coarse serials, pulses and oil seeds, have very low yields.

Degradation of cultivable land: One of the serious problems that arise out of the faulty strategy of irrigation and agricultural development is degradation of land resources. It leads to depletion of soil fertility. In irrigated areas, a large track of agricultural land lost its fertility due to alkalisation and salinization of soils and waterlogging. Excessive use of chemicals such as insecticides and pesticides has led to their concentration in toxic amounts in the soil profile. Leguminous crops have been displaced from the cropping pattern in the irrigated areas and duration of fellow has substantially reduced owing to multiple cropping. This has obliterated the process of natural fertilization such as nitrogen fixation. Rain fed areas also experience degradation of several types like soil erosion by water and wind erosion, which are often induced by human activities.

(ii) What are the important strategies for agricultural development followed in the post-independence in India?

Ans. Indian agricultural economy was largely subsistence in nature before independence. During partition, about 1/3 of the irrigated land of undivided India went to Pakistan. After independence, the immediate goal of the government was to increase food grain production by:

1. a) Switching over from cash crops to food crops
2. b) Intensification of cropping over already cultivated land
3. c) Increasing cultivated area by bringing cultivable and fallow land under plough

Later intensive agricultural district program (IADP) and Intensive Agricultural Area Programme (IAAP) were launched. But two consecutive droughts during mid-1960s resulted in food crisis in the country.

New seed varieties of wheat (Mexico) and rise (Philippines) known as high yielding varieties (HYV) were available for cultivation by later 1960s, India took advantage of this and introduced package technology comprising HYV along with chemical fertilizers in irrigated areas of Punjab, Haryana, western Uttar Pradesh, Andhra Pradesh and Gujarat leading fast agricultural growth. This spurt of agricultural growth came to be known as Green Revolution. This also gave fillip to the development of a large number of agro inputs, agro processing industries and small scale industries. This strategy of agricultural development made the country self-reliant in food grain production.

The Planning Commission of India focused its attention on the problems of agriculture in rain fed areas in 1980s. It initiated agro climatic planning in 1988 to induce regionally balanced agricultural development in the country. It also emphasised the need for diversification of agriculture and harnessing of resources for development of dairy farming, poultry, horticulture, livestock rearing and aquaculture.
