Land Resources and Agriculture
1. Chapter Summary (Quick Revision Note)
Land is a crucial natural resource, and its utilization is categorized by the land revenue department into various classes such as forests, barren and wastelands, land put to non-agricultural uses, permanent pastures, culturable wastelands, and net sown area. Over the years, India has witnessed significant land-use changes driven by the growing size of the economy and a structural shift from agriculture to industrial and service sectors. Consequently, the area under non-agricultural uses has expanded rapidly at the expense of agricultural land and wastelands. Alongside private land, Common Property Resources (CPRs) like community forests and pastures play a vital role in the rural economy by providing fodder, fuel, and livelihood support to landless and marginal farmers.
Agriculture is the backbone of the Indian economy, heavily dependent on land quality and availability. India has three distinct cropping seasons: Kharif (coinciding with the southwest monsoon), Rabi (winter season), and Zaid (a short summer season). Farming practices are broadly divided into irrigated farming (protective and productive) and rainfed farming (dryland and wetland), depending on the source of moisture. India produces a wide variety of crops, including foodgrains like rice, wheat, jowar, and pulses, which occupy about two-thirds of the total cropped area. Additionally, commercial crops like oilseeds, cotton, jute, sugarcane, tea, and coffee are cultivated extensively across different agro-climatic zones.
Following Independence, India adopted several strategies to boost agricultural production, most notably the Green Revolution in the 1960s, which introduced High Yielding Varieties (HYVs) of seeds, chemical fertilizers, and assured irrigation. While this made India self-reliant in foodgrains, Indian agriculture still faces severe challenges. These include heavy dependence on an erratic monsoon, low productivity, financial constraints leading to farmer indebtedness, lack of effective land reforms, and the uneconomic fragmentation of landholdings. Furthermore, faulty irrigation practices and excessive use of chemicals have led to severe land degradation, causing problems like soil salinization, alkalization, and waterlogging, which threaten the long-term sustainability of agriculture.

Q2. Answer the following questions in about 30 words.
(i) Differentiate between barren and wasteland and culturable wasteland.
Answer: Barren and wasteland includes terrains like rocky areas, deserts, and ravines that cannot be brought under cultivation using currently available technology. Culturable wasteland, however, is land left uncultivated for more than five years but can be brought under cultivation after improving it through reclamation practices.
(ii) How would you distinguish between net sown area and gross cropped area?
Answer: Net sown area refers to the physical extent of land on which crops are sown and harvested at least once during an agricultural year. Gross cropped area is the total area sown once as well as more than once in a particular year; it accounts for the total volume of crop production.
(iii) Why is the strategy of increasing cropping intensity important in a country like India?
Answer: In a land-scarce but labor-abundant country like India, increasing cropping intensity is crucial because the scope for expanding the net sown area is limited. Growing multiple crops on the same land in a year increases total agricultural output and generates more employment opportunities for the rural workforce.
(iv) How do you measure total cultivable land?
Answer: Total cultivable land is measured by adding up the net sown area, all types of fallow lands (current fallow and fallow other than current fallow), and culturable wasteland.
(v) What is the difference between dryland and wetland farming?
Answer: Dryland farming is practiced in regions with annual rainfall less than 75 cm, focusing on drought-resistant crops like ragi and bajra, and employing soil moisture conservation techniques. Wetland farming is practiced in areas where rainfall exceeds the soil moisture requirement, suitable for water-intensive crops like rice, jute, and sugarcane.
Q3. Answer the following questions in about 150 words.
(i) What are the different types of environmental problems of land resources in India?
Answer: The environmental problems affecting land resources in India are primarily driven by faulty agricultural practices and natural agents. In heavily irrigated areas, excessive watering without proper drainage has led to severe waterlogging. This process brings underground salts to the surface, resulting in the alkalization and salinization of soils, which drastically reduces soil fertility. Furthermore, the excessive use of chemical fertilizers and pesticides has led to toxic concentrations in the soil profile, harming the natural ecosystem.
Additionally, the practice of multiple cropping has reduced the duration of fallow periods, preventing the soil from naturally replenishing its nutrients, such as through nitrogen fixation by leguminous crops. In rainfed, semi-arid, and humid regions, land degradation occurs largely through soil erosion caused by water and wind, often exacerbated by human activities like deforestation and overgrazing. These combined factors convert vast tracts of productive agricultural land into degraded wastelands.
(ii) What are the important strategies for agricultural development followed in the post-independence period in India?
Answer: After Independence, India’s immediate agricultural strategy focused on increasing foodgrain production to combat severe shortages. This was initially done by switching from cash crops to food crops, intensifying cropping on existing lands, and bringing fallow and culturable wastelands under the plough. However, when production stagnated in the late 1950s, the government introduced the Intensive Agricultural District Programme (IADP) and the Intensive Agricultural Area Programme (IAAP).
The most significant breakthrough came in the mid-1960s with the Green Revolution. This strategy involved introducing High Yielding Varieties (HYVs) of wheat from Mexico and rice from the Philippines, combined with the extensive use of chemical fertilizers, pesticides, and assured irrigation. This package technology made India self-reliant in foodgrains. Later, in the 1980s, the Planning Commission initiated agro-climatic planning to ensure regionally balanced development, focusing on rainfed areas and encouraging the diversification of agriculture into dairy, poultry, and horticulture.

Short Questions (1-2 Marks):
1. Name the three distinct crop seasons in India. [1 Mark]
Answer: The three distinct crop seasons in India are Kharif, Rabi, and Zaid.
2. What is the main objective of protective irrigation? [1 Mark]
Answer: The main objective of protective irrigation is to protect crops from the adverse effects of moisture deficiency by acting as a supplementary source of water over and above the rainfall.
3. Which state is the largest producer of rice in India? [1 Mark]
Answer: West Bengal is the leading rice-producing state in India.
4. Give two examples of plantation crops grown in India. [1 Mark]
Answer: Two examples of plantation crops grown in India are Tea and Coffee.
5. What is meant by ‘Current Fallow’? [2 Marks]
Answer: Current fallow is the land which is intentionally left without cultivation for one or less than one agricultural year. This cultural practice is adopted to give the land rest so it can recoup its lost fertility through natural processes.
Long Questions (3-5 Marks):
6. Discuss the role of Common Property Resources (CPRs) in the rural economy of India. [3 Marks]
Answer: Common Property Resources (CPRs) include community forests, pasture lands, and village water bodies that are owned by the state but meant for community use. They are highly crucial for the livelihood of landless and marginal farmers who rely on them to graze their livestock. CPRs provide essential resources like fodder, fuel wood, fruits, nuts, and medicinal plants. They are particularly important for rural women, who bear the primary responsibility of collecting fuel and fodder for their households.
7. Explain the impact of the Green Revolution on Indian agriculture. [3 Marks]
Answer: The Green Revolution, introduced in the mid-1960s, transformed Indian agriculture by utilizing High Yielding Varieties (HYVs) of seeds, chemical fertilizers, and assured irrigation. It led to a massive and rapid increase in the production of foodgrains, particularly wheat and rice, making India self-reliant and eliminating the need for food imports. It also stimulated the growth of agro-processing and agricultural machinery industries. However, its initial confinement to irrigated areas like Punjab and Haryana led to regional disparities in agricultural development.
8. Differentiate between Kharif and Rabi cropping seasons. [3 Marks]
Answer: The Kharif season coincides with the onset of the Southwest Monsoon (June to September) and is suitable for cultivating tropical crops that require high moisture, such as rice, cotton, jute, and jowar. In contrast, the Rabi season begins with the onset of winter (October to March) and is suited for temperate and subtropical crops that require cooler temperatures, such as wheat, gram, and mustard. While Kharif crops rely heavily on monsoon rains, Rabi crops are mostly grown under irrigated conditions.
9. Analyze the problem of small and fragmented landholdings in India. [3 Marks]
Answer: A major institutional constraint in Indian agriculture is the small and fragmented nature of landholdings. Due to the high population pressure and the traditional laws of inheritance, land is continuously divided among successive generations. These tiny, fragmented plots become highly uneconomic for cultivation because it is difficult and expensive to use modern farm machinery, tractors, or efficient irrigation systems on them. This fragmentation ultimately leads to low agricultural productivity and keeps farmers trapped in poverty.
10. Describe the geographical conditions required for the cultivation of Cotton in India and name its major producing states. [5 Marks]
Answer: Cotton is a tropical crop grown primarily in the Kharif season in the semi-arid areas of the country. It requires a warm climate and clear skies during its flowering stage to ensure good quality fiber. It grows best in the moisture-retentive black soils of the Deccan Plateau, though it is also successfully cultivated in the irrigated tracts of the northwestern plains.
India grows both short-staple (Indian) and long-staple (American, known as ‘narma’) cotton. The major cotton-producing states in India are Gujarat, Maharashtra, and Telangana. It is also grown in parts of Punjab, Haryana, Rajasthan, Andhra Pradesh, and Karnataka.
4. Additional Important Q&A (10 Questions)
Short Questions (1-2 Marks):
1. How is cropping intensity calculated? [1 Mark]
Answer: Cropping intensity is calculated by dividing the Gross Cropped Area (GCA) by the Net Sown Area (NSA) and multiplying the result by 100. (Cropping Intensity = GCA / NSA × 100).
2. Name the three crops of rice grown in a single agricultural year in West Bengal. [1 Mark]
Answer: The three crops of rice grown in West Bengal are ‘aus’, ‘aman’, and ‘boro’.
3. What is productive irrigation? [2 Marks]
Answer: Productive irrigation is a strategy meant to provide sufficient soil moisture in the cropping season to achieve high productivity. In this system, the water input per unit area of cultivated land is much higher than in protective irrigation, aiming for maximum crop yield rather than just saving the crop from drought.
4. Why is the yield of pulses generally low in India? [2 Marks]
Answer: The yield of pulses is generally low and fluctuates from year to year because they are primarily cultivated as rainfed crops in the drylands of the Deccan and central plateaus, where moisture availability is highly erratic and irrigation facilities are minimal.
5. What is the main objective of the National Mission for Sustainable Agriculture (NMSA)? [2 Marks]
Answer: The main objective of NMSA is to make agriculture more productive, sustainable, remunerative, and climate-resilient. It promotes location-specific integrated farming systems and the conservation of natural resources through appropriate soil and moisture conservation measures.
Long Questions (3-5 Marks):
6. How does the structural change in the economy affect land-use patterns in India? [3 Marks]
Answer: As the Indian economy grows, its composition undergoes a structural change, with the secondary (industrial) and tertiary (service) sectors growing much faster than the primary (agricultural) sector. This economic shift leads to a gradual transfer of land from agricultural uses to non-agricultural uses. As industries, urban settlements, roads, and infrastructure expand, they consume agricultural land and wastelands. This change is particularly sharp around large urban areas, where fertile agricultural land is frequently converted for building and commercial purposes.
7. Discuss the importance of pulses in the Indian agricultural economy. [3 Marks]
Answer: Pulses hold immense importance in the Indian agricultural economy for two main reasons. First, they are a crucial ingredient in the predominantly vegetarian Indian diet, serving as a primary and rich source of protein. Second, pulses are leguminous crops; their root nodules contain bacteria that fix atmospheric nitrogen into the soil. This natural process increases soil fertility, making pulses an essential component of crop rotation practices to maintain the health of agricultural lands.
8. Why is agricultural productivity low in the dry regions of India? [3 Marks]
Answer: Agricultural productivity is low in dry regions primarily due to the severe lack of soil moisture and high dependence on an erratic monsoon. These areas receive less than 75 cm of annual rainfall and lack adequate irrigation infrastructure. Consequently, farmers are forced to grow coarse, low-yielding, drought-resistant crops like jowar, bajra, and ragi. Furthermore, the soils in these regions often lack sufficient nutrients, and the farmers, being economically marginalized, cannot afford expensive inputs like modern seeds and fertilizers, leading to overall low productivity.
9. Write a note on the cultivation of Tea in India. [3 Marks]
Answer: Tea is a highly important plantation crop and beverage in India, indigenous to the hills of northern China. It requires an undulating topography (hill slopes) to prevent waterlogging, well-drained soils, and a humid, sub-tropical climate. In India, tea cultivation began in the 1840s in the Brahmaputra valley of Assam, which remains the largest producing region, accounting for over half of the country’s output. Other major producing areas include the sub-Himalayan regions of West Bengal (Darjeeling, Jalpaiguri) and the lower slopes of the Nilgiri and Cardamom hills in South India.
10. Explain how financial constraints and indebtedness act as major hurdles for Indian farmers. [5 Marks]
Answer: Modern agriculture is highly resource-intensive, requiring expensive inputs such as High Yielding Variety (HYV) seeds, chemical fertilizers, pesticides, and machinery. The vast majority of Indian farmers are small and marginal landholders with meager incomes and virtually no savings. To purchase these necessary inputs, they are forced to borrow money.
Since formal credit institutions are often inaccessible to poor farmers, they rely on local moneylenders who charge exorbitant interest rates. If the monsoon fails or crops are destroyed by pests, the farmers suffer huge losses and cannot repay their loans. This pushes them into a vicious cycle of severe indebtedness. The psychological and economic pressure of this debt trap is so immense that it has tragically led to a rising number of farmer suicides across various states in India, making it one of the most critical challenges in the agricultural sector.
