Ans:

Q.1. Classify industries on the basis of :
 (a) Capital investment,
 (b) Ownership
 (c) Bulk and weight of raw material and finished product.

Ans. Industries can be classified into the following categories :

(a) On the basis of capital investment :

1. Large scale industries make large capital investment of more than one crore of rupees. They employ large numbers of people and use a large number of machineries, e.g. cotton textile.
2. Small scale industries involve capital outlay of less than one crore rupees, employ a smaller number of labourers and use few power driven machineries, e.g. cycle parts manufacturing.

(b) On the basis of ownership :

1. Public sector industries are owned and operated by government agencies, e.g. Rourkela Steel Plant.
2. Private sector industries are owned and operated by an individual or a group of individuals, e.g. Bajaj Auto Ltd.
3. Joint sector industries are jointly run by the state and individual entrepreneurs e.g. Oil India Ltd.
4. Cooperative sector industries are owned and managed by the producers and suppliers of raw materials or by workers. They pool in their resources and share the profits and losses proportionately, e.g., sugar industry in Maharashtra.

(c) On the basis of bulk or weight of raw material and finished products :

1. Heavy industries use bulky raw materials and their finished products are also heavy, e.g., iron and steel industry.
2. Light industries use light raw materials and their finished products are also light, eg. electrical industries producing bulbs.

Q.2. Mention the factors responsible for localisation of cotton textile industry in Maharashtra- Gujarat region in early years. What factors were responsible for the decentralisation of the industry? Mention three main problems faced by the industry. What is the contribution of textile industry to Indian economy?

Q1. Multipurpose river projects are referred as the ‘temples of modern India.’ Elucidate. OR Why did Jawaharlal Nehru proudly proclaim the dams as the temples of modern India? (2010)

Ans: Multipurpose River Projects were initiated after Independence to manage water resources effectively. They aimed to provide various benefits that would foster national development, overcoming the limitations of the colonial era.

Jawaharlal Nehru referred to these modern dams as ‘temples of modern India’ because they:

• Integrate agricultural development with rapid industrialisation.
• Support both rural and urban economies.

The key benefits of these multipurpose projects include:

• Providing water to areas facing water scarcity.
• Irrigating fields during dry seasons, enhances agricultural productivity.
• Controlling floods by regulating water flow.
• Supplying water for domestic and industrial use.
• Generating hydroelectricity for homes and industries.
• Facilitating inland navigation for transport and trade.
• Supporting fish breeding.
• Offering recreational facilities.
• Promoting soil conservation through afforestation.

Q2. In recent years, multipurpose projects and large dams have come under great scrutiny and opposition. Explain why. (2010) OR What objections have been raised against multipurpose river valley projects? Explain any three.

Ans: In recent years, multipurpose projects and large dams have faced significant scrutiny and opposition for several reasons:

• Natural Flow Disruption: Regulating and damming rivers alters their natural flow, leading to poor sediment flow and increased sedimentation at the reservoir’s bottom. This results in rockier stream beds, which are less suitable for aquatic life.
• Fragmentation: Dams fragment rivers, hindering the migration and spawning of aquatic species.
• Vegetation Loss: Reservoirs created on floodplains submerge existing vegetation and soil, causing their decomposition over time.
• Flood Control Failures: Ironically, dams intended for flood control can trigger floods due to sediment buildup and excessive water release during heavy rains.
• Community Displacement: Projects like the ‘Narmada Bachao Andolan’ highlight the large-scale displacement of local communities, who lose their livelihoods when forced off their land.
• Social Inequality: Benefits often accrue to landowners, large farmers, and industrialists, while displaced locals receive little support, widening the gap between rich and poor.

Q3. What are interstate water disputes? Why are such issues raised? Give examples of interstate water disputes.

Ans: Interstate water disputes occur when two or more states experience tension over the sharing of river water, often due to the construction of multipurpose projects. These disputes arise from disagreements on the costs and benefits associated with these projects. When a river flows through multiple states, actions taken in one state, such as damming, can significantly impact the flow and availability of water in another state. This can lead to one state benefiting while another suffers, resulting in conflicts.

Examples of interstate water disputes include:

• Krishna-Godavari dispute: Involves Karnataka and Andhra Pradesh objecting to Maharashtra’s diversion of more water from the Koyna tributary for a hydroelectric project, which reduces downstream flow.
• Kaveri water dispute: A conflict between Karnataka and Tamil Nadu over the sharing of Kaveri river water.
• Narmada River dispute: Involves Rajasthan, Madhya Pradesh, Gujarat, and Maharashtra.
• Ravi-Beas dispute: A disagreement between Punjab and Haryana.
• Mandovi-Mahadayi-Vansadhara dispute: Involves Goa, Karnataka, Andhra Pradesh, and Odisha.

Q4. Write about the rooftop rainwater harvesting system prevalent in Meghalaya. How is the bamboo drip irrigation system employed for water harvesting in Meghalaya?

Ans: Rooftop rainwater harvesting is a common practice in Shillong, Meghalaya. Despite being near Mawsynram, the wettest place on Earth, Shillong faces significant water shortages due to its location in a rainshadow area. As a result:

• Most households have rainwater harvesting systems.
• These systems collect rainfall for use during dry periods.
• Approximately 15-25% of household water needs are met through this method.

The bamboo drip irrigation system in Meghalaya is a traditional method that has been in use for over 200 years. Key features include:

• Bamboo pipes are used to collect and transport water from springs and streams.
• This system utilises gravity to move water from hilltops to lower areas.
• About 18-20 litres of water can flow through the bamboo pipes, which can transport it over long distances.
• The water flow is carefully controlled by adjusting the pipe positions, delivering water directly to plant roots.
• At the plant site, the flow reduces to 20-80 drops per minute.

Q5. An area or region may have ample water resources but still face water scarcity. Explain why such circumstances arise.

Ans: Water scarcity in areas with ample water resources can occur due to several factors:

• Population Growth: A dense and increasing population leads to higher water demand, straining existing resources.
• Unequal Access: Water distribution is often unequal, particularly affecting rural areas where access is limited.
• Domestic and Agricultural Needs: More water is needed for domestic use and to support expanding irrigation for food production. This can result in over-exploitation of water resources.
• Industrial Demand: The rise in industries increases water consumption, putting additional pressure on freshwater supplies.
• Pollution: Water resources can become unusable due to pollution from industrial effluents, agricultural chemicals, and domestic waste, further contributing to scarcity.

Q6. Identify the reasons (any three) for water scarcity specially, in metropolitan towns. Suggest one measure that in your opinion can lead to a more equitable distribution of available water supply.

Ans: Reasons for water scarcity in metropolitan towns:

• Dense population: Urban lifestyles lead to higher water consumption. Many housing societies rely on groundwater pumping, causing depletion of water levels.
• Industrial demand: Industries and multinational corporations consume large amounts of water, putting pressure on existing freshwater resources.
• Water pollution: The discharge of domestic and industrial waste into water bodies contributes to water scarcity.

A potential solution for a more equitable distribution of water is the linking of river systems in India. This approach can transfer water from areas with a surplus to those facing shortages.

Q7. Water is available in abundance in India but even then scarcity of water is experienced in major parts of the country. Explain with four examples.

Ans: India receives nearly 4 per cent of the world’s precipitation, with total renewable water resources estimated at 1,897 sq km per annum. Despite this abundance, many regions in India face severe water scarcity. Currently, India ranks 133rd globally in water availability per person per annum, and by 2025, large parts of the country may experience absolute water scarcity.

Here are four examples illustrating this issue:

• Rajasthan: This desert region receives very low rainfall and is prone to drought, leading to regular water shortages.
• Metropolitan Cities: Cities like Mumbai and Kolkata face acute water shortages due to their large populations and high water demands.
• Urban Lifestyle: High water consumption in urban areas, coupled with over-exploitation of groundwater, contributes to water scarcity.
• Agricultural Demand: Intensive agriculture requires significant water resources, leading to depletion and further scarcity.

Q8. How have intensive industrialisation and urbanisation passed a great pressure on existing freshwater resources in India? Explain with two examples for each.

Ans: Intensive industrialisation and urbanisation in India have significantly stressed existing freshwater resources. Here are some examples illustrating their impact:

• Effects of industrialisation:
  • Industries, such as cotton textile mills in Maharashtra and jute mills in West Bengal, consume large amounts of water.
  • Heavy water use leads to the over-exploitation of local freshwater sources.
  • Discharge of industrial waste has polluted major rivers like the Ganga and Yamuna, making them hazardous for human use.
• Effects of urbanisation:
  • Metropolitan cities like Mumbai and Kolkata face severe water shortages due to their dense populations.
  • Urban lifestyles increase water and energy demands, exacerbating the scarcity.
  • Many housing societies rely on groundwater pumping, leading to the depletion of fragile water resources.

Q1. Why was Project Tiger launched? What are its objectives? What are its effects on the conservation of wildlife?

Ans: The tiger is a crucial species in the wildlife ecosystem. In 1973, authorities discovered that the tiger population had plummeted to 1,827 from an estimated 55,000 at the start of the century. Major threats to tigers include:

• Poaching for trade
• Loss of habitat
• Human population growth
• Deforestation

Poaching for skins and bones is the primary reason for the drastic decline, pushing tigers towards extinction. With India and Nepal housing about two-thirds of the world’s tigers, they became prime targets for illegal activities.

Project Tiger, launched in India in 1973, aims to:

• Ban hunting and poaching of tigers, Restrict trade of tiger skins and bones.
• Provide legal protection to habitats by creating tiger reserves, such as Corbett National Park and the Sunderbans
• Increase the tiger population through natural breeding.

Initially, Project Tiger was successful, with the tiger population rising to 4,002 in 1985 and 4,334 in 1989. However, by 1993, the population had dropped to 3,600, and it continues to decline alarmingly. Tiger conservation is not only about saving an endangered species but also about preserving significant biotypes.

Q2. Discuss the role of local communities in the conservation of forests with the help of examples.

Ans: Local communities play a crucial role in forest conservation in India, often relying on forests for their livelihoods. Their involvement varies from collaboration with government officials to independent protection efforts.

• In Sariska Tiger Reserve, Rajasthan, villagers successfully opposed mining activities by invoking the Wildlife Protection Act.
• In Alwar district, five villages declared 1,200 hectares of forest as Bhairodev Dakav ‘Sonchuri’, establishing their own rules to protect wildlife and banning hunting.
• The Bishnois of Rajasthan are renowned for safeguarding endangered species like black bucks, nilgai, and peacocks.
• The Chipko Movement in the Himalayas, led by local communities, particularly women, effectively resisted deforestation and promoted community-led afforestation with native species.
• Movements such as Beej Bachao Andolan and Navdanya have revived traditional conservation methods and promoted ecological farming.
• The Joint Forest Management programme exemplifies local community involvement in managing and restoring degraded forests.

Q3. What are ‘sacred groves’? Give examples of some species of flora which are worshipped by the tribals. How has the ‘sacredness’ ascribed to plants and animals helped in protecting them?

Sacred Grooves

Ans: Sacred groves are untouched forests that local communities protect, viewing them as sacred spaces. This ancient belief in nature worship leads to the preservation of these areas, which often host diverse and rare species.

Many tribal societies hold specific plants as sacred, including:

• Mahua (Bassia latifolia) and Kadamba (Anthocaphalus cadamba) trees worshipped by the Mundas and Santhals in Chhotanagpur.
• Tamarind (Tamarindus indica) and Mango (Mangifera indica) trees revered during weddings by tribes in Odisha and Bihar.
• Peepal and Banyan trees, commonly considered sacred across India.

The ascribed sacredness of these plants and animals plays a crucial role in their protection:

• Many animals, such as macaques and langurs, are cared for by temple devotees.
• In Bishnoi villages, animals like blackbuck, nilgai, and peacocks are protected by the community.

Q4. Write a short note on Joint Forest Management. What have been the effect of Beej Bachao Andolan towards conservation of forests?

Ans: Joint Forest Management (JFM) in India is a successful approach that engages local communities in the management and restoration of degraded forests. Key aspects include:

• Formation of local village institutions to protect forest land.
• Community members receive benefits such as access to non-timber forest products (e.g., fruits, nuts, honey) and a share of timber.
• Established in 1988, JFM promotes community involvement in forest conservation.

The Beej Bachao Andolan has significantly contributed to forest conservation by:

• Advocating for ecological farming and reviving traditional conservation methods.
• Demonstrating that diverse crop production can be economically viable without synthetic chemicals.
• Encouraging sustainable practices that benefit both the environment and local communities.

Q5. Write a note on the programmes accepted for conserving forest and wildlife in India.

Ans: Conserving forests and wildlife is crucial for maintaining ecological diversity and supporting our life systems. The National Forest Policy in India focuses on:

• Maintaining environmental stability by preserving and restoring ecological balance.
• Increasing forest cover through afforestation and social forestry initiatives.
• Meeting the demand for fuel, fodder, and minor forest products by enhancing forest productivity.

For wildlife conservation, India has implemented several key measures:

• Established 106 national parks, 564 wildlife sanctuaries, and 18 biosphere reserves.
• Enforced the Wildlife Protection Act.
• Protected endangered species by banning hunting and safeguarding their habitats.
• Initiated projects like Project Tiger, Project Rhino, and Project Elephant to protect threatened species in their natural environments.
• Created 27 tiger reserves under Project Tiger and identified four coral reefs for conservation.
• Linked many wetlands with the river system for better management.
