RESOURCES AND DEVELOPMENT
Introduction
Resources are all things available in the environment which can satisfy human needs. They are considered resources only when they are technologically accessible, economically feasible and culturally acceptable.
Classification of Resources
On the basis of origin, resources are biotic or abiotic. On the basis of exhaustibility, they are renewable or non-renewable. On the basis of ownership, they are individual, community, national or international. On the basis of the stage of development, they are potential, developed, stock or reserves.
Development of Resources
The development of resources has created serious problems like depletion, pollution, and unequal distribution. Therefore sustainable development has become essential. It means development which meets the needs of the present without compromising the ability of future generations to meet their needs.
Resource Planning in India
Resource planning is important because resources are unevenly distributed across the country. It involves identification and inventory of resources, evolving a proper planning structure with technology, skills and institutions, and matching resource development with overall national development plans.
Land Resources
India has 3.28 million square kilometres of land which is used for agriculture, forests, pastures, wasteland, settlements and industries. Land degradation is a serious problem caused by deforestation, overgrazing, mining, over-irrigation and industrial waste. Conservation measures include afforestation, regulated grazing, controlled mining and proper irrigation.
Soil as a Resource
Soil is formed by the weathering of rocks and decomposition of organic matter. Major soil types in India are alluvial soil in river plains, black soil in the Deccan plateau, red and yellow soil rich in iron, laterite soil in high rainfall areas, arid soil in deserts, and forest soil in hilly regions.
Soil Erosion and Conservation
Soil erosion is the removal of the top fertile layer of soil by wind, water and human activity. It can be controlled through contour ploughing, terrace farming, strip cropping, planting shelter belts and afforestation.
SHORT QUESTION AND ANSWER
Q1. What is a resource?
A resource is anything available in the environment that can satisfy human needs. However, it becomes a resource only when it is technologically accessible, economically feasible and culturally acceptable. Resources may be natural or man-made, and they play a vital role in human development and survival.
Q2. How are resources classified on the basis of origin?
On the basis of origin, resources are divided into biotic and abiotic. Biotic resources include all living things such as forests, animals, and humans, while abiotic resources include non-living things such as land, water, minerals and metals. Both are essential for economic activities and overall development.
Q3. Give two examples of biotic resources.
Biotic resources are those obtained from the biosphere which are living or have life. For example, forests provide wood, fruits and oxygen, while animals provide milk, meat, wool and labour. Human beings are also considered biotic resources because of their intelligence and ability to develop technology.
Q4. Give two examples of abiotic resources.
Abiotic resources are non-living and are often physical in nature. For instance, land is used for agriculture, housing, and industries, while minerals such as iron, bauxite, and copper are important raw materials for manufacturing. Water is another abiotic resource which is necessary for drinking, irrigation and electricity.
Q5. How are resources classified on the basis of exhaustibility?
Resources are classified into renewable and non-renewable on the basis of exhaustibility. Renewable resources such as wind, water, and solar energy can be replenished naturally and reused. Non-renewable resources like coal, petroleum, and natural gas take millions of years to form and cannot be regenerated quickly.
Q6. Give examples of renewable resources.
Renewable resources are those which can regenerate naturally. For example, solar energy can be continuously used without depletion. Wind energy is also renewable and can be converted into electricity. Similarly, water resources and forests are renewable if they are properly managed and conserved for long-term use.
Q7. Give examples of non-renewable resources.
Non-renewable resources are limited in quantity and take millions of years to form. For example, coal and petroleum are fossil fuels that provide energy but once consumed cannot be quickly replaced. Excessive use of such resources leads to depletion, and therefore they must be used carefully and judiciously.
Q8. How are resources classified on the basis of ownership?
Resources are divided into four categories on the basis of ownership. Individual resources are owned privately like a farmer’s land. Community resources are accessible to all like village ponds. National resources belong to the entire nation, and international resources are regulated by global institutions beyond national boundaries.
Q9. Give one example of an individual resource.
An individual resource is one that is owned privately by a person. For example, a farmer’s agricultural field is his individual resource. He uses it for crop production to earn livelihood. Similarly, houses, plots, or privately owned cars also come under individual resources in our daily life.
Q10. Give one example of a community resource.
Community resources are those which can be accessed by all the members of a community. For instance, village grazing grounds, burial grounds, parks and ponds are community resources. These are maintained by the community and serve the common needs of people living in that particular locality.
Q11. What are national resources?
National resources are all resources found within the political boundaries and territorial waters of a country. They belong to the nation and are controlled by the government. Examples include forests, minerals, roads, railways and land. The government can use them for the benefit of the entire population.
Q12. Give one example of an international resource.
International resources are those which lie beyond the jurisdiction of any one nation. For example, the resources found in ocean waters beyond 200 nautical miles from the coast are considered international resources. They are regulated by international organisations such as the United Nations to ensure fair and equitable use.
Q13. What are potential resources?
Potential resources are those which are found in a region but are not yet fully used. They have the capacity to be utilised in the future. For instance, solar and wind energy in states like Rajasthan and Gujarat have immense potential but are not yet fully exploited.
Q14. Give an example of potential resources in India.
In India, Rajasthan and Gujarat have great potential for solar and wind energy because of their climate and geographical conditions. Although the resources are abundant, they have not been harnessed completely. Proper technology and investment are required to use these potential resources for generating power in the future.
Q15. What are developed resources?
Developed resources are those which have been surveyed and their quality and quantity determined for utilisation. These resources are already in use to fulfil human needs. For example, coal, petroleum, natural gas, and iron ore in India have been explored and are widely used in industries.
Q16. What are stock resources?
Stock resources are those available in nature but which cannot be used due to the absence of suitable technology. For instance, hydrogen and oxygen in water can be used as a source of energy, but presently we do not have the required advanced technology to harness them properly.
Q17. Give an example of stock resources.
A good example of stock resources is hydrogen present in water. Although it has the potential to be used as a powerful source of energy, the advanced technology required to make it usable on a large scale is not yet economically viable or practically available for us.
Q18. What are reserves?
Reserves are a part of stock resources which can be used with the existing technology but are kept for future requirements. For instance, the water stored in dams is a reserve because it is available for use, but it is utilised only when necessary for irrigation or electricity.
Q19. Define sustainable development.
Sustainable development means using resources in such a way that present needs are met without harming the future generation’s ability to use them. It is a balanced approach which combines growth with conservation. This concept is necessary today to prevent over-exploitation and destruction of natural resources worldwide.
Q20. Why is resource planning necessary in India?
Resource planning is necessary because resources in India are unevenly distributed. Some states like Jharkhand and Chhattisgarh are rich in minerals, while Rajasthan has solar and wind energy. Other regions may lack these. Hence, systematic planning is needed to ensure balanced regional development and proper use of resources.
Q21. What is the first step of resource planning in India?
The first step of resource planning is identification and inventory of resources. This includes surveying land, water, soil, minerals and energy resources. Their quality, quantity, and distribution are studied so that they can be properly used for present and future needs in different regions of the country.
Q22. What is the total geographical area of India?
The total geographical area of India is about 3.28 million square kilometres. This vast land supports agricultural activities, industries, settlements, forests, and other uses. Because of increasing pressure of population and developmental activities, careful planning and conservation are essential to maintain the productivity of this valuable land resource.
Q23. Mention two causes of land degradation.
Land degradation occurs due to natural and human causes. Deforestation reduces soil fertility and increases erosion. Overgrazing by cattle damages the grass cover. Mining leaves pits and scars on land. Over-irrigation increases salinity. Industrial wastes also pollute land. These factors together reduce the quality and productivity of soil.
Q24. Mention two methods of land conservation.
Land conservation can be done through several practices. Afforestation increases vegetation cover and checks soil erosion. Regulated grazing prevents overuse of grasslands. Proper irrigation techniques avoid waterlogging and salinity. Reclaiming land damaged by mining and reducing industrial effluents are also important steps to conserve and protect land resources.
Q25. Name the most fertile soil in India.
The most fertile soil in India is alluvial soil. It is found mainly in the northern plains and river valleys. Rich in nutrients like potash, phosphoric acid and lime, it supports crops such as wheat, rice, maize and sugarcane. Its fertility makes it ideal for intensive agricultural practices.
Q26. Which soil is suitable for cotton cultivation?
Black soil, also called regur soil, is suitable for cotton cultivation. It is found mainly in the Deccan plateau, especially in Maharashtra, Madhya Pradesh and Gujarat. Black soil retains moisture for a long time and is rich in calcium carbonate and potash, making it highly productive for cotton farming.
Q27. In which states are red and yellow soils found?
Red and yellow soils are found in Odisha, Chhattisgarh, southern parts of Karnataka and Jharkhand. These soils develop from crystalline igneous rocks. The red colour is due to iron, while yellow colour appears when iron is in a hydrated form. They are less fertile but support millets and pulses.
Q28. Where is laterite soil found?
Laterite soil is found in regions of high rainfall and high temperature, such as Karnataka, Kerala, Tamil Nadu and Assam. It is formed due to intense leaching. Though poor in fertility, it is suitable for crops like tea, coffee and cashew with proper fertilisers. It is also used for bricks.
Q29. What is soil erosion?
Soil erosion is the removal of the top fertile layer of soil by natural forces such as wind and water or by human activities like deforestation, overgrazing and unscientific farming. It leads to loss of fertility and productivity of land. Erosion must be controlled to maintain soil health.
Q30. Name two methods to prevent soil erosion.
Two important methods to prevent soil erosion are contour ploughing and terrace farming. Contour ploughing across slopes reduces water runoff, while terrace farming on hilly areas prevents soil from being washed away. Afforestation and strip cropping are also widely used to conserve soil and maintain its fertility.
LONG QUESTION AND ANSWER
Q1. Define resources. How are they important for human beings?
Resources are all things present in the environment that can satisfy human needs when they are technologically accessible, economically feasible, and culturally acceptable. They form the backbone of human existence because food, shelter, clothing, energy, transport, and industrial growth depend on them. For example, soil provides crops, forests give wood and raw materials, and minerals supply energy and metals. The availability and use of resources determine the level of development of a country. Proper and planned utilization of resources ensures progress and maintains balance with the environment. Without resources, survival and growth of human civilization would be impossible.
Q2. Explain the classification of resources on the basis of origin with examples.
Resources are classified into two types on the basis of origin: biotic and abiotic. Biotic resources are derived from living organisms. Examples include forests, animals, fisheries, and human beings themselves. They provide food, raw materials, and ecological balance. Abiotic resources are derived from non-living things. These include land, water, minerals, and metals. They support industries, energy production, and agriculture. Both types are equally important. For example, agriculture needs soil (abiotic) as well as seeds and cattle (biotic). Together, biotic and abiotic resources form the foundation of human life and development, and their balanced use ensures sustainability.
Q3. Differentiate between renewable and non-renewable resources with examples.
Renewable resources are those that can be replenished by natural processes. They include solar energy, wind, forests, water, and agricultural crops. They are available in abundance if used carefully. Non-renewable resources are limited in supply and take millions of years to form. Examples are coal, petroleum, natural gas, and metallic minerals. Overuse of these resources leads to depletion and ecological imbalance. For instance, petroleum reserves are fast reducing due to high demand. If we do not shift to renewables, future generations may face severe shortages. Thus, sustainable use of both renewable and non-renewable resources is necessary for long-term development.
Q4. Write about individual and community resources with examples.
Resources can be classified based on ownership into individual and community resources. Individual resources are privately owned by individuals. Examples are agricultural land owned by farmers, houses, plots, or vehicles. Community resources are accessible to all people of a community and are used collectively. Examples include grazing grounds, village ponds, parks, burial grounds, and playgrounds. While individual resources help in meeting personal needs, community resources ensure equality and shared development. Both categories are essential for society. For instance, a farmer may depend on his private land for cultivation but also use community pastures for cattle grazing. Balanced access promotes harmony.
Q5. Explain the meaning of national resources with examples.
National resources are those that belong to an entire nation and are under the control of the government. These include minerals, forests, water bodies, roads, railways, and wildlife within the country’s boundaries. The government has the authority to acquire and regulate private property for public good. For instance, the land acquired for constructing highways becomes a national resource. The Exclusive Economic Zone (200 nautical miles from the coastline) also comes under national resources. In India, coal, petroleum, natural gas, and water resources are considered national property. These resources play a vital role in economic growth, security, and development of the country.
Q6. Explain international resources with examples.
International resources are those that lie beyond the political boundaries of any nation and are managed by international organisations such as the United Nations. For example, oceanic resources beyond 200 nautical miles of a country’s Exclusive Economic Zone belong to all nations. Minerals, oil, natural gas, and marine life in deep oceans are considered international resources. Antarctica and outer space are also treated as global commons. No single country can exploit these alone without international agreements. These resources highlight the principle of global cooperation and shared responsibility. Rational use of international resources is essential to prevent conflict and ensure equity.
Q7. Explain potential and developed resources with examples.
Potential resources are those found in a region but not yet fully utilized. For example, solar and wind energy in Rajasthan and Gujarat, or uranium reserves in Ladakh. They hold great future possibilities but require technology and investment for exploitation. Developed resources, on the other hand, are surveyed, measured, and their quantity and quality are known. They are actively used in the present, like coal, petroleum, and iron ore deposits in India. Developed resources are essential for industries and economy. Both types are vital—potential resources represent future opportunities, while developed resources meet present needs and sustain the economy.
Q8. Differentiate between stock and reserve resources with examples.
Stock resources are present in the environment but cannot be used due to lack of suitable technology. For example, hydrogen and oxygen can be used as energy resources, but we lack technology for their large-scale utilization. Reserves are a part of stock resources which can be used with existing technology but are kept for future use. For example, water stored in dams for generating hydroelectricity is considered a reserve. Stock resources symbolize future possibilities, while reserves provide a buffer for emergencies. The distinction helps in resource planning, as some resources are conserved deliberately for sustainable growth.
Q9. Why is sustainable development necessary?
Sustainable development is essential to balance present needs with future requirements. Unplanned use of resources leads to depletion, pollution, and ecological imbalance. For example, deforestation and over-mining degrade land and harm biodiversity. Sustainable development ensures that natural resources are used responsibly, conserving them for future generations. It promotes practices like renewable energy, recycling, afforestation, and eco-friendly technologies. In India, the growing population and industrialization have put immense pressure on resources, making sustainability crucial. Without it, the survival of human civilization will be threatened. Thus, sustainable development is the only way to ensure economic growth without damaging the environment.
Q10. State Gandhiji’s view on resource use. How is it relevant today?
Mahatma Gandhi believed that “There is enough for everybody’s need, but not for anybody’s greed.” He opposed reckless exploitation of resources, stating that overuse causes inequality and harm to the environment. His view emphasized moral responsibility in resource use, highlighting that selfishness leads to ecological imbalance. Today, his principle is more relevant than ever. With rising consumerism, over-extraction of fossil fuels, deforestation, and pollution, the Earth is under threat. Gandhi’s philosophy forms the foundation of sustainable development. It teaches us to reduce waste, conserve resources, and focus on equity. Thus, his message remains a guiding light globally.
Q11. Why is resource planning important in India?
Resource planning is important because resources are unevenly distributed across India. While states like Jharkhand and Odisha are rich in minerals, states like Rajasthan lack water resources. Some areas have fertile soil while others are arid. Without planning, this imbalance leads to inequality and underdevelopment. Resource planning ensures optimum use of resources, balanced regional growth, and sustainable development. It involves identifying resources, using appropriate technology, and linking development with national goals. With a growing population and limited resources, India cannot afford overuse or wastage. Thus, resource planning is vital for reducing regional disparity, achieving economic growth, and conserving for the future.
Q12. Mention the three steps of resource planning in India.
The first step is identifying and creating an inventory of resources across regions. This includes surveying the availability of soil, water, minerals, and forests. The second step involves planning for development with proper technology, skills, and institutional support. This ensures that resources are developed in a scientific manner. The third step is matching resource development plans with overall national development strategies. For example, agricultural resource planning must align with food security policies. These three steps ensure equitable use, reduce wastage, and promote sustainable development. Proper planning allows India to overcome regional disparities and make effective use of its diverse resources.
Q13. Write about India’s land resources and their utilization.
India’s total land area is about 3.28 million square kilometres. Land resources are used for agriculture, forestry, pastures, housing, industries, mining, and transport. Around 54 percent of land is used for agriculture, about 22 percent is under forests, while the remaining is wasteland, pastures, and settlements. However, distribution is uneven, and many areas face land degradation. Intensive farming, urbanization, and deforestation have put pressure on land. Thus, proper utilization is essential to balance ecological and economic needs. Measures like afforestation, controlled grazing, and efficient urban planning are necessary to maintain land productivity. Land is a vital, limited resource that requires careful management.
Q14. What are the major causes of land degradation in India?
Land degradation in India occurs due to both human and natural factors. Deforestation removes protective cover and exposes soil to erosion. Overgrazing by cattle destroys vegetation and leads to barren lands. Mining leaves deep scars and dumps waste that pollutes soil. Over-irrigation causes waterlogging and salinity in agricultural fields, especially in Punjab and Haryana. Industrial and urban waste further pollutes land. Shifting cultivation, common in north-eastern states, also contributes to degradation. Natural causes like floods and droughts worsen the problem. If not controlled, land degradation reduces fertility, threatens food security, and leads to ecological imbalance. Thus, urgent conservation is required.
Q15. Suggest measures to control land degradation.
Several measures can control land degradation. Afforestation is the most effective, as planting trees prevents soil erosion and restores fertility. Overgrazing must be regulated to protect vegetation cover. Proper management of mining activities and filling of pits can reduce land scars. In agricultural areas, crop rotation, organic farming, and controlled irrigation help maintain fertility. Waterlogging and salinity can be prevented through efficient drainage systems. Industrial effluents should be treated before disposal. In arid regions, shelter belts of trees and stabilisation of sand dunes are effective methods. By adopting these conservation techniques, land can be protected, restored, and used sustainably for generations.
Q16. How is soil formed and what are the factors affecting soil formation?
Soil is formed through the long process of weathering of rocks combined with decomposition of organic matter. It takes thousands of years to form just one centimetre of soil. The main factors influencing soil formation are parent rock, relief, climate, vegetation, and time. Parent rock determines mineral content, while relief affects drainage. Climate influences the rate of weathering through rainfall and temperature. Vegetation adds humus and organic matter to the soil. Time is crucial because soil formation is a slow process. Together, these factors create different soil types across India, each with unique fertility and characteristics suitable for specific crops.
Q17. Describe the features and distribution of alluvial soil.
Alluvial soil is the most fertile soil in India, covering the northern plains formed by the deposition of rivers like the Ganga, Brahmaputra, and Indus. It is rich in potash, lime, and phosphoric acid but lacks nitrogen. This soil is suitable for crops like wheat, paddy, sugarcane, and pulses. Alluvial soil is divided into two types: khadar (new alluvium) which is more fertile, and bhangar (old alluvium) which is less fertile. It is mainly found in states like Punjab, Haryana, Uttar Pradesh, Bihar, and West Bengal. Its fertility supports India’s agriculture and makes the northern plains one of the most productive regions.
Q18. Describe the features and distribution of black soil.
Black soil, also called regur soil, is ideal for cotton cultivation, hence also known as “black cotton soil.” It is found in Maharashtra, Madhya Pradesh, Gujarat, Andhra Pradesh, and parts of Tamil Nadu. It is rich in calcium carbonate, magnesium, potash, and lime but poor in nitrogen and phosphorus. Black soil has high moisture-retention capacity, making it suitable for dry farming. It develops deep cracks during summers, which help in aeration of the soil. Besides cotton, crops like wheat, millets, oilseeds, and pulses grow well in this soil. Its fertility makes it an important agricultural resource in central India.
Q19. Write about red and yellow soils, with examples of crops grown.
Red and yellow soils develop on crystalline igneous rocks. They appear red due to iron oxide and turn yellow when hydrated. These soils are found in Odisha, Chhattisgarh, southern Karnataka, Jharkhand, and parts of Tamil Nadu. They are less fertile, being deficient in nitrogen, phosphorus, and humus. However, with proper irrigation and fertilisers, crops like cotton, wheat, pulses, millets, and oilseeds can be cultivated. These soils are generally sandy to clayey in texture and require scientific management to increase productivity. Despite limitations, red and yellow soils support millions of farmers, particularly in eastern and southern India, by sustaining agriculture.
Q20. Write about laterite soil, its characteristics, and crops grown.
Laterite soil is found in areas of high temperature and heavy rainfall. The soil is formed due to intense leaching, which washes away silica and leaves iron and aluminium oxides, giving it a reddish-brown colour. It is poor in humus, nitrogen, and lime but can be made fertile with manure and fertilisers. Laterite soil is found in Karnataka, Kerala, Tamil Nadu, Madhya Pradesh, and hilly areas of Odisha and Assam. It supports crops like tea, coffee, cashew, and rubber. Although less fertile naturally, laterite soil is useful for plantation agriculture when managed scientifically. Its distribution reflects India’s climatic diversity.
Q21. Explain the need for sustainable development with examples.
Answer: Sustainable development is necessary because unplanned exploitation of resources has caused many problems like resource depletion, deforestation, land degradation, and pollution. For example, over-irrigation has led to soil salinity and waterlogging, while industrialization has polluted rivers. If present generations continue to consume recklessly, future generations will face severe shortages. Sustainable development emphasizes balancing economic growth with environmental protection. It involves using renewable resources carefully, conserving non-renewable ones, and adopting eco-friendly technologies. Initiatives such as rainwater harvesting, afforestation, recycling, and renewable energy use are practical examples that help ensure long-term environmental balance and human well-being.
Q22. Discuss the problems created by the indiscriminate use of resources.
Answer: Indiscriminate use of resources has resulted in serious global and national issues. Excessive exploitation has led to resource depletion, where essential resources like minerals, forests, and freshwater are declining. Overuse of fossil fuels has caused environmental pollution and global warming. Land degradation due to deforestation, mining, and overgrazing has reduced soil fertility. The unequal distribution of resources has created economic and social inequality between regions and communities. These problems highlight the urgent need for planned and balanced use of resources. Without proper conservation measures, both ecological balance and human survival will be at great risk in the near future.
Q23. Explain the process of resource planning in India.
Answer: Resource planning in India is done in three important stages. The first stage involves the identification and inventory of resources through surveys and mapping of natural resources such as land, water, soil, forests, and minerals. The second stage involves developing a proper planning structure with suitable technology, institutions, and skilled personnel to use resources efficiently. The third stage ensures matching resource development plans with national and regional development strategies. This approach helps in addressing the uneven distribution of resources across the country. Proper resource planning ensures sustainable development and reduces the gap between resource-rich and resource-poor regions.
Q24. What are the causes of land degradation in India?
Answer: Land degradation in India has multiple causes. Deforestation is one major factor, as removal of trees exposes soil to erosion. Overgrazing by animals in states like Gujarat and Rajasthan leads to soil erosion. Mining activities destroy land surfaces and pollute surrounding areas. Over-irrigation in states like Punjab, Haryana, and western Uttar Pradesh has caused waterlogging and salinity, making soil infertile. Industrial waste also pollutes land. Shifting cultivation in the north-eastern states is another reason for degradation. These causes threaten agricultural productivity and ecological balance, making conservation efforts like afforestation and regulated grazing highly necessary for sustainable land use.
Q25. Suggest measures to conserve land resources in India.
Answer: Conservation of land resources is essential for maintaining ecological balance and ensuring future agricultural productivity. Measures include afforestation and tree plantation to check soil erosion. Regulated grazing should be promoted to prevent overuse of pastures. Proper management of mining activities and reclamation of mined areas can restore degraded land. Adopting scientific techniques of irrigation, such as drip and sprinkler systems, can prevent salinity and waterlogging. Contour ploughing and terrace farming in hilly areas reduce soil erosion. Community awareness and government initiatives are equally important. By implementing these measures, land degradation can be minimized, and land resources can be sustained.
Q26. Describe the main characteristics of alluvial soil.
Answer: Alluvial soil is one of the most important soils in India, found in the northern plains and river valleys. It is formed by the deposition of silt and sediments brought by rivers such as the Ganga, Brahmaputra, and Indus. This soil is very fertile and rich in potash, phosphoric acid, and lime, making it suitable for crops like wheat, rice, sugarcane, and pulses. It is light in texture, ranging from sandy loam to clayey loam. It is renewed every year during floods, which increases fertility. Its wide distribution and productivity make it the backbone of Indian agriculture.
Q27. Explain the distribution and features of black soil in India.
Answer: Black soil, also known as regur soil, is mainly found in the Deccan plateau regions of Maharashtra, Madhya Pradesh, Gujarat, Andhra Pradesh, and Tamil Nadu. It is formed from the weathering of igneous rocks like basalt. The soil is clayey in nature, retains moisture for a long time, and becomes very sticky when wet but develops deep cracks when dry, which aids aeration. Black soil is rich in calcium carbonate, magnesium, potash, and lime but poor in phosphorous. It is highly suitable for growing cotton, which is why it is also called "black cotton soil."
Q28. What are the characteristics and uses of laterite soil?
Answer: Laterite soil is formed under conditions of high temperature and heavy rainfall, where leaching washes away soluble minerals, leaving behind iron and aluminum-rich soil. It is mainly found in Karnataka, Kerala, Tamil Nadu, Madhya Pradesh, and hilly areas of Odisha and Assam. The soil is generally red in color due to the presence of iron oxides. Though not very fertile naturally, with proper manuring and fertilization, it can support crops such as tea, coffee, and cashew nuts. Its hardness also makes it useful as a building material in certain regions.
Q29. Describe the process and impact of soil erosion in India.
Answer: Soil erosion is the removal of the top layer of fertile soil by natural agents like wind and water, as well as human activities. In India, soil erosion occurs due to deforestation, overgrazing, shifting cultivation, and faulty farming practices. Wind erosion is common in arid regions like Rajasthan, while water erosion affects river valleys and hilly areas. The impact of soil erosion is severe, as it reduces soil fertility, decreases agricultural productivity, and leads to desertification. Controlling soil erosion through methods like afforestation, contour ploughing, and terrace farming is essential to preserve the fertility of Indian soils.
Q30. Suggest various methods of soil conservation practiced in India.
Answer: Soil conservation in India is achieved through several scientific and traditional methods. Contour ploughing, where ploughing is done along the contour lines, prevents water runoff. Terrace farming in hilly areas reduces soil erosion and conserves moisture. Strip cropping involves alternating strips of crops to check wind erosion. Shelter belts of trees are planted to break the force of wind in dry areas like Rajasthan. Afforestation and reforestation also help in binding soil. Adoption of proper irrigation techniques like drip systems prevents salinization. Together, these measures maintain soil fertility and ensure sustainable agricultural productivity for future generations.
