In conclusion, the sugar industry in North and Peninsular India differs significantly due to various factors such as climatic conditions, availability of raw materials, production techniques, government policies, and infrastructure facilities. The sugar industry in North India is characterized by higher sugarcane production and outdated technology, while the industry in Peninsular India is marked by the use of alternative raw materials, modern technology, and a strong cooperative movement.

Q.2. (a)  Landslide is a major problem in the Himalayan region. Discuss its causes and mitigation measures. 

Landslide is a major problem in the Himalayan region due to the fragile nature of the terrain, steep slopes, and heavy rainfall. Landslides in the Himalayas have resulted in significant loss of life, damage to infrastructure, and disruption of communication networks. Some major landslides in the Himalayan region include the Uttarakhand disaster in 2013, the Darjeeling landslide in 2015, and the Arunachal Pradesh landslide in 2017.

Causes of landslides in the Himalayan region:

1. Geology: The Himalayan region consists of young, weak, and folded rocks, which are prone to landslides. The weak geological structure and high tectonic activity make the region susceptible to slope failures.

2. Steep slopes: The steep slopes in the Himalayan region increase the gravitational force acting on the slope materials, making them more prone to landslides.

3. Heavy rainfall: The Himalayan region receives heavy rainfall during the monsoon season, which leads to saturation of the soil and increased pore water pressure. This reduces the cohesion between soil particles and weakens the slope material, triggering landslides.

4. Deforestation: The large-scale deforestation in the Himalayan region has resulted in the loss of vegetation cover, which acts as a natural barrier against landslides. The roots of trees and plants help in binding the soil and increasing its shear strength.

5. Construction activities: The construction of roads, highways, and other infrastructure in the Himalayan region has led to slope cutting and destabilization, making the slopes more prone to landslides.

6. Anthropogenic factors: Overgrazing, mining activities, and agricultural practices can also lead to landslides by disturbing the natural stability of the slopes.

Mitigation measures for landslides in the Himalayan region:

1. Hazard mapping: Identifying and mapping landslide-prone areas can help in planning and implementing appropriate mitigation measures.

2. Slope stabilization: Engineering techniques like retaining walls, slope terracing, and drainage systems can help in stabilizing slopes and reducing the risk of landslides.

3. Afforestation: Planting trees and vegetation on slopes can help in increasing the soil's shear strength and reducing the risk of landslides.

4. Early warning systems: Installing early warning systems like rain gauges, slope inclinometers, and ground movement sensors can help in monitoring the slope stability and providing timely warnings to the people living in landslide-prone areas.

5. Land-use planning: Land-use planning should be done in such a way that it minimizes the exposure of people and infrastructure to landslide hazards. Construction activities in high-risk landslide zones should be restricted.

6. Community-based disaster management: Local communities should be involved in landslide hazard mitigation measures, as they have a better understanding of the local conditions and can respond quickly during a landslide event.

7. Capacity building: Training and capacity-building programs should be conducted for local government officials, engineers, and other stakeholders involved in landslide hazard management.

In conclusion, landslides are a major problem in the Himalayan region and pose a significant threat to life, property, and the environment.

(b) Appraise why drought is one of the most common climatic extremes in India

Drought is one of the most common climatic extremes in India due to a combination of factors such as the country's monsoon-dependent agricultural system, high population density, and the increasing impact of climate change. The following points appraise the reasons behind the prevalence of droughts in India:

1. Monsoon dependence: India's agriculture is heavily dependent on the monsoon rains, which account for around 75% of the country's annual rainfall. The South-West monsoon, which arrives in June and lasts until September, is crucial for the Kharif crop season. Any delay or failure in the arrival of monsoons or uneven distribution of rainfall can lead to drought-like conditions in various parts of the country. For example, the droughts of 1987 and 2002 were caused by a significant deficit in monsoon rainfall.

2. El Niño effect: The El Niño Southern Oscillation (ENSO) phenomenon, which involves the periodic warming and cooling of the equatorial Pacific Ocean, has a significant impact on India's monsoons. El Niño events are generally associated with a weakening of the monsoon and reduced rainfall, leading to droughts. For instance, the severe droughts of 2009 and 2014 in India were linked to strong El Niño events.

3. Climate change: Global warming and climate change have been altering the patterns of monsoons, making them more erratic and unpredictable. The increasing frequency and intensity of extreme weather events, such as heatwaves, storms, and floods, also contribute to the vulnerability of India's agriculture to droughts. For example, the 2015-2016 drought affected more than 330 million people across the country, primarily due to consecutive years of poor monsoons and rising temperatures.

4. High population density and water demand: India's large and growing population puts immense pressure on the country's water resources, leading to overexploitation of groundwater and heightened vulnerability to droughts. In many regions, the demand for water exceeds the available supply, leading to increased dependence on monsoon rains. For example, the 2016 drought in the Marathwada region of Maharashtra was exacerbated by the over-extraction of groundwater for irrigation.

5. Land use and agricultural practices: Unsustainable land-use patterns and agricultural practices, such as water-intensive cropping patterns and inefficient irrigation systems, contribute to the depletion of water resources and increased vulnerability to droughts. For instance, the widespread cultivation of water-guzzling crops like sugarcane and rice in drought-prone areas adds to the stress on water resources.

6. Inadequate drought management policies: The lack of comprehensive drought management policies and early warning systems in India further exacerbates the impacts of droughts. The country's drought management strategies often focus on short-term relief measures, such as providing drinking water and employment opportunities, rather than long-term measures to build resilience against droughts, such as improving irrigation efficiency, promoting climate-resilient crops, and enhancing water conservation efforts.

In conclusion, the prevalence of droughts in India can be attributed to the country's monsoon-dependent agricultural system, the influence of global climatic phenomena like El Niño, the impact of climate change, high population density and water demand, unsustainable land use and agricultural practices, and inadequate drought management policies. Addressing these challenges through a combination of short- and long-term measures is crucial for enhancing India's resilience to droughts and ensuring food and water security for its population.

(c) Discuss the ecological and economic challenges of river linking in India. 

River linking in India refers to the inter-basin transfer of water from surplus river basins to deficit ones, with the primary objective of alleviating regional imbalances in water resources and reducing the recurrent floods and droughts. The ambitious National River Linking Project (NRLP) aims to connect 37 Himalayan and peninsular rivers through 30 links, including 14,900 km of canals. While the project is expected to bring significant benefits, such as increased irrigation, improved water supply, and enhanced power generation, it also poses several ecological and economic challenges that must be addressed.

Ecological Challenges:

1. Loss of biodiversity: River linking may cause significant habitat loss and fragmentation, leading to the decline of aquatic and terrestrial biodiversity. For example, the Ken-Betwa river link project could submerge about 4,141 hectares of the Panna Tiger Reserve, threatening the habitat of tigers, vultures, and other endangered species.

2. Altered river flow patterns: Inter-basin water transfers can lead to changes in the natural flow patterns of rivers, affecting the hydrological and geomorphological processes. This may result in increased erosion, sedimentation, and downstream flooding. The proposed linking of the Brahmaputra and Ganga rivers, for instance, could alter the natural flow patterns, impacting millions of people living in the Ganga-Brahmaputra-Meghna basin.

3. Disruption of aquatic ecosystems: The mixing of waters from different rivers can lead to the transfer of pollutants, invasive species, and diseases, disrupting the ecological balance of the recipient river basin. For example, the proposed Par-Tapi-Narmada river link could transfer pollution from the heavily polluted Tapi River to the relatively cleaner Narmada River.

4. Impact on wetlands and floodplains: River linking projects may lead to the destruction of crucial wetlands and floodplains that provide essential ecosystem services, such as water purification, flood mitigation, and habitat for various species. The proposed Damanganga-Pinjal link, for example, could affect the ecologically sensitive Sanjay Gandhi National Park and Thane Creek Flamingo Sanctuary in Maharashtra.

Economic Challenges:

1. High financial costs: The estimated cost of the NRLP is around INR 5.6 lakh crore (approximately USD 75 billion), making it one of the most expensive infrastructure projects in India. The high investment required raises concerns about the financial viability and cost-effectiveness of the project, especially considering the limited funds available for other essential sectors like health, education, and social welfare.

2. Displacement and rehabilitation: River linking projects may lead to large-scale displacement of local communities, particularly tribal and marginalized populations, who depend on the rivers for their livelihoods. The rehabilitation and resettlement of these communities pose significant social and economic challenges. For instance, the Ken-Betwa river link project is expected to displace over 6,000 families, requiring comprehensive rehabilitation plans and financial compensation.

3. Inter-state conflicts: River linking projects often involve the transfer of water across state boundaries, which may lead to conflicts and disputes among states over water-sharing arrangements. The proposed Godavari-Krishna-Pennar-Cauvery river link, for example, has been a source of contention among the states of Andhra Pradesh, Karnataka, and Tamil Nadu.

4. Economic feasibility: The potential benefits of river linking, such as increased irrigation and hydropower generation, must be weighed against the long-term ecological costs and the availability of alternative, less disruptive solutions for addressing water scarcity. Techniques like rainwater harvesting, watershed management, and demand-side management could potentially address water scarcity issues in a more sustainable and cost-effective manner.

In conclusion, while the river linking projects in India have the potential to address regional imbalances in water resources and mitigate the impacts of floods and droughts, it is essential to carefully consider the ecological and economic challenges associated with such large-scale interventions. An integrated, participatory approach that takes into account the environmental, social, and economic aspects of river linking is crucial for ensuring the long-term sustainability of India's water resources.

Q.4.(a) Discuss the reserves, distribution, and production of all varieties of coal in India. 

Coal is one of the most significant sources of energy in India, accounting for approximately 55% of the country's energy needs. India ranks third in the world in terms of coal reserves and production. The coal reserves in India can be broadly classified into four varieties, namely, Anthracite, Bituminous, Lignite, and Peat.

1. Anthracite: It is the highest quality coal with the highest carbon content (above 80%) and very low volatile matter. It has high heating value and is used for industrial and metallurgical purposes. Anthracite reserves in India are limited and mainly found in the Jammu & Kashmir region.

2. Bituminous: It has a carbon content ranging between 45% to 80% and is the most abundant type of coal found in India. It is commonly used for power generation, cement production, and as a coking coal in the steel industry. Major bituminous coal reserves are found in the states of Jharkhand, Odisha, Chhattisgarh, West Bengal, Madhya Pradesh, Telangana, and Maharashtra. The major coalfields include Jharia, Raniganj, Bokaro, Talcher, Singrauli, and Korba.

3. Lignite: Also known as brown coal, lignite has a carbon content of 40% to 55%. It is a low-grade coal with high moisture and ash content. Lignite is mainly used for power generation in thermal power plants. Major lignite reserves are found in the states of Tamil Nadu (Neyveli), Rajasthan (Palana, Bikaner), Gujarat (Kutch, Surat), and Jammu & Kashmir (Poonch).

4. Peat: It has the lowest carbon content (less than 40%) and is the initial stage of coal formation. Peat is not used for commercial purposes in India due to its low heating value and high moisture content.

Distribution and Production:

India's coal reserves are primarily distributed across the Gondwana and Tertiary formations. The Gondwana coalfields, which are around 300 million years old, account for nearly 98% of India's coal reserves. They are mainly found in the peninsular regions, including the Damodar Valley (Jharkhand and West Bengal), Mahanadi Valley (Odisha), and Godavari Valley (Andhra Pradesh and Telangana). The Tertiary coalfields, which are around 60 million years old, are found in the northeastern states of Assam, Arunachal Pradesh, and Nagaland.

As of 2020, India's total coal reserves are estimated to be around 319 billion tonnes. The major coal-producing states in India are Jharkhand, Odisha, Chhattisgarh, West Bengal, Madhya Pradesh, Telangana, and Maharashtra. In the financial year 2019-20, India produced around 729 million tonnes of coal, with the public sector company Coal India Limited (CIL) accounting for nearly 80% of the production.

(b) Describe the salient features of the east-flowing rivers of India. 

The east-flowing rivers in India play a significant role in the country's hydrology, ecology, and socio-economic development. These rivers predominantly flow towards the Bay of Bengal and contribute to the fertile plains, agriculture, and the livelihood of millions of people. The salient features of the east-flowing rivers of India are as follows:

1. Origin: The east-flowing rivers of India mainly originate from the Western Ghats, the Eastern Ghats, and the central highlands of the country. Notable east-flowing rivers include the Godavari, Krishna, Kaveri, Mahanadi, Damodar, and Brahmani.

2. Drainage Basin: These rivers have large and well-developed drainage basins. For instance, the Godavari river basin covers an area of about 3,12,812 sq. km, making it the largest river basin in peninsular India. Similarly, the Krishna river basin covers an area of about 2,58,948 sq. km.

3. Tributaries: The east-flowing rivers have numerous tributaries, which contribute to the water volume and support the riverine ecosystem. For example, the Godavari river has tributaries like the Pravara, Purna, Manjira, and Sabari, while the Krishna river has tributaries like Tungabhadra, Bhima, and Koyna.

4. Length: The east-flowing rivers are generally long, with some spanning over a thousand kilometers. The Godavari, for instance, is the second-longest river in India, with a length of about 1,465 km. The Krishna river is also one of the longest rivers in India, with a length of about 1,400 km.

5. Water Flow: These rivers are perennial and have a consistent flow of water throughout the year. However, they are also prone to flooding during the monsoon season, which may cause damage to crops and infrastructure. For example, the Kaveri river is known for its seasonal fluctuations, with heavy floods during the monsoons and water scarcity during the summers.

6. Agriculture: The east-flowing rivers contribute significantly to the agricultural productivity of India. They provide water for irrigation, which supports the cultivation of crops like rice, sugarcane, and cotton. For instance, the Godavari Delta is known as the Rice Bowl of Andhra Pradesh due to its fertile soil and abundant water resources.

7. Hydroelectric Power: Several hydroelectric power projects have been developed on the east-flowing rivers to harness their potential for generating electricity. Notable examples include the Srisailam Dam on the Krishna river, the Hirakud Dam on the Mahanadi river, and the Mettur Dam on the Kaveri river.

8. Navigation: Some of the east-flowing rivers, like the Godavari and the Brahmani, are navigable for a considerable distance, providing inland water transport facilities for the movement of goods and people.

9. Biodiversity: The east-flowing rivers support a rich and diverse ecosystem, which includes a variety of flora and fauna. For instance, the Sundarbans Delta, formed by the Ganges and Brahmaputra rivers, is home to the Royal Bengal Tiger and other unique species.

10. Cultural Significance: These rivers hold immense cultural and religious significance for the people of India. Many important pilgrimage sites and historical monuments are located along the banks of these rivers, such as the temples of Puri and Konark on the shores of the Mahanadi river and the temple towns of Rajahmundry and Bhadrachalam along the Godavari river.

(c) Critically examine the problems of Inter-State border disputes in India.

Inter-State border disputes in India have been a persistent issue since the country's independence in 1947. The root of these disputes can be traced back to the linguistic, cultural, and historical differences among Indian states. The partition of British India into India and Pakistan, followed by the reorganization of Indian states based on linguistic lines in 1956, further complicated the boundary issues between various states. In this context, it is crucial to critically examine the problems of Inter-State border disputes in India, taking into account some prominent examples.

1. Historical and Political Factors: The historical and political factors behind the border disputes mainly involve the legacy of British colonial rule and the princely states' integration into the Indian Union. In many cases, the border disputes are a result of ambiguous demarcation or lack of proper demarcation during the reorganization of states. For instance, the Assam-Nagaland border dispute primarily stems from the unclear demarcation of the boundary during the formation of Nagaland in 1963.

2. Linguistic and Cultural Differences: The linguistic and cultural differences between states have often exacerbated border disputes. The reorganization of states based on linguistic lines has led to a sense of regionalism and cultural identity, further fueling the conflicts. For example, the Maharashtra-Karnataka border dispute over the Belgaum district is mainly due to the linguistic differences between the Marathi-speaking population of the district and the Kannada-speaking state of Karnataka.

3. Economic Factors: Economic factors, such as the presence of natural resources, fertile agricultural land, and water resources, have also played a significant role in the border disputes between states. For instance, the Punjab-Haryana border dispute is mainly due to the sharing of river water resources between the two states.

4. Administrative and Legal Issues: The lack of proper administrative and legal mechanisms to resolve border disputes has further aggravated the problem. In many cases, the disputes have been pending before the courts for a long time, leading to a lack of resolution and continued tensions between states. For example, the Supreme Court of India is still hearing the case of the Assam-Mizoram border dispute, which has led to violent clashes between the two states in recent years.

5. Law and Order Problems: The border disputes often lead to law and order problems, such as violence, arson, and loss of life and property. The persistent clashes between the people of the disputed regions often create a sense of insecurity and fear among the local population. The recent violent clashes between the people of Assam and Mizoram, leading to the loss of lives and property, is a glaring example of this issue.

In conclusion, the problems of Inter-State border disputes in India are multifaceted and deeply rooted in historical, political, linguistic, cultural, and economic factors. The lack of proper administrative and legal mechanisms to resolve these disputes further exacerbates the issue. It is essential for the Indian government to address these problems through dialogue, negotiation, and legal means to ensure peaceful coexistence and harmony among the states. Additionally, fostering a sense of national identity, along with respect for regional and cultural differences, can help mitigate these disputes and promote unity in diversity.
