The Himalayas, one of the most significant mountain ranges in the world, play a crucial role in the drainage system of the Indian subcontinent. The region’s complex topography and climatic conditions contribute to a diverse and dynamic network of rivers and tributaries. Here’s a detailed discussion of the drainage system of the Himalayas with recent examples:

1. Major Rivers Originating from the Himalayas:

Definition: The major rivers originating from the Himalayas are fundamental to the drainage system and have significant hydrological, ecological, and economic impacts. These rivers are primarily fed by glaciers, snowmelt, and monsoon rains.

Examples:

• Ganges (Ganga): Originating from the Gangotri Glacier in Uttarakhand, the Ganges is a vital river for northern India. It flows through several states and is central to the region’s cultural and economic life. In recent years, the river has faced challenges due to pollution, leading to various government and NGO-led initiatives for its cleaning, such as the Namami Gange Programme.
• Yamuna: The Yamuna River, which is a major tributary of the Ganges, originates from the Yamunotri Glacier. The river flows through the capital city, Delhi, where it faces significant pollution issues. Recent efforts have focused on improving wastewater management to address the contamination of the Yamuna.

2. Rivers of the Indus Basin:

Definition: The Indus Basin rivers are another major component of the Himalayan drainage system. They originate in the western Himalayas and flow towards the arid regions of Pakistan.

Examples:

• Indus River: Originating from the Tibetan Plateau, the Indus flows through northern India and into Pakistan. It is crucial for the agriculture of Pakistan. Recent challenges include water disputes between India and Pakistan, and issues related to water scarcity due to glacial melt and climate change.
• Jhelum, Chenab, Ravi: These rivers, which are tributaries of the Indus, also originate from the western Himalayas. They are significant for both India and Pakistan. In recent times, the region has seen concerns related to water management and flood control.

3. Rivers of the Brahmaputra Basin:

Definition: The Brahmaputra Basin rivers are another critical segment of the Himalayan drainage system, originating from the eastern Himalayas and flowing towards the northeast of India and Bangladesh.

Examples:

• Brahmaputra: Originating from the Tibet Autonomous Region, the Brahmaputra flows through India’s Assam and Bangladesh. It is prone to flooding during the monsoon season, leading to significant agricultural and infrastructural impacts. Recent efforts have been made to improve flood management and irrigation systems in Assam.
• Teesta: Originating from the eastern Himalayas, the Teesta River flows through Sikkim and West Bengal. It has seen recent attention due to issues related to hydroelectric projects and water-sharing disputes between India and Bangladesh.

4. Rivers of the Eastern Himalayas:

Definition: The rivers of the Eastern Himalayas play a crucial role in draining the northeastern part of the Indian subcontinent.

Examples:

• Subansiri: A major tributary of the Brahmaputra, the Subansiri originates in Arunachal Pradesh. Recent concerns include the impact of hydropower projects on the river’s ecology and local communities.
• Dibang: Also in Arunachal Pradesh, the Dibang River is significant for its role in the hydrological system of the region. Issues related to dam construction and environmental impacts have been prominent.

5. Glacial and Snowmelt Influence:

Definition: Many rivers in the Himalayas are fed by glacial melt and snowmelt, which significantly influences their flow patterns and seasonal variations.

Examples:

• Gangotri Glacier: The source of the Ganges River, this glacier is crucial for the river’s flow during the dry season. Recent studies have shown a rapid melting of the Gangotri Glacier, which could impact the water availability in the Ganges.
• Siachen Glacier: Situated in the northern region of the Himalayas, the Siachen Glacier feeds the Nubra River. Glacial melt from this region is crucial for the rivers flowing into the Indus Basin. Recent concerns include the impact of climate change on glacier retreat and its effects on downstream water resources.

Conclusion

The drainage system of the Himalayas is a complex and dynamic network with major rivers originating from different segments of the range, including the western, central, and eastern Himalayas. Recent examples highlight ongoing issues related to pollution, water management, and climate change, emphasizing the need for sustainable practices to protect these vital water resources. Understanding the drainage system of the Himalayas is crucial for managing water resources, mitigating flood risks, and addressing environmental challenges in the region.

Classification of Mountains Based on Geomorphological Characteristics

Mountains are significant landforms that can be classified based on their geomorphological characteristics, which pertain to their origin, structure, and formation processes. Here’s a detailed classification along with recent examples:

1. Fold Mountains:

Definition: Fold mountains are formed primarily by the collision of tectonic plates, which causes the Earth’s crust to fold. These mountains are characterized by complex structures with numerous folds, including anticlines (upward folds) and synclines (downward folds).

Examples:

• Himalayas: Formed by the collision of the Indian Plate with the Eurasian Plate, the Himalayas include notable peaks like Mount Everest. This region is still tectonically active, and earthquakes are common.
• Andes: Stretching along the western coast of South America, the Andes result from the subduction of the Nazca Plate beneath the South American Plate. Recent volcanic activity in Chile, like the 2023 eruption of the Láscar Volcano, exemplifies the ongoing geological activity in this range.

2. Block Mountains:

Definition: Block mountains, also known as fault-block mountains, are created by tectonic forces that cause the Earth’s crust to fracture into blocks. These blocks are then uplifted or down-dropped relative to each other along faults.

Examples:

• Sierra Nevada: Located in the western United States, the Sierra Nevada mountains are a classic example of block mountains. The uplifted block forms high peaks like Mount Whitney, and recent seismic activity has highlighted the tectonic processes shaping this range.
• Vosges Mountains: Situated in northeastern France, these mountains are also block mountains, characterized by their uplifted blocks and significant fault lines.

3. Volcanic Mountains:

Definition: Volcanic mountains are formed by volcanic activity where magma from the Earth’s mantle erupts through the crust, creating cones or domes of volcanic material.

Examples:

• Mount Fuji: This iconic peak in Japan is a stratovolcano that erupted last in 1707. It is a prominent example of volcanic mountains formed by repeated explosive and effusive volcanic activity.
• Kilauea: Located in Hawaii, Kilauea is one of the world’s most active volcanoes. Its recent eruptions, such as those in 2021, have added new land and reshaped the landscape around it.

4. Residual Mountains:

Definition: Residual mountains, also known as denudation mountains, are formed through the process of erosion. They are typically old mountains that have been worn down over time, leaving behind remnants of their original structure.

Examples:

• Appalachian Mountains: This mountain range in eastern North America is a classic example of residual mountains. Erosion has worn down the once-high peaks, leaving behind rounded, eroded landforms.
• Aravalli Range: Located in India, the Aravalli Range is one of the oldest mountain ranges in the world. Its current form is the result of extensive erosion and denudation over millions of years.

5. Dome Mountains:

Definition: Dome mountains are formed when magma pushes the Earth’s crust upwards without erupting. The uplifted rock forms a dome shape, which may later be eroded to expose the underlying structure.

Examples:

• Black Hills: Located in South Dakota, USA, the Black Hills are an example of dome mountains. The region features rounded peaks like Harney Peak, and the uplifted granite domes are a result of ancient volcanic activity.
• Gros Ventre Range: Found in Wyoming, USA, this range showcases dome-like structures formed by tectonic forces pushing the crust upward.

Conclusion

The classification of mountains based on geomorphological characteristics provides insight into their formation processes and structural features. Recent geological activities and studies in regions like the Himalayas, Sierra Nevada, and Kilauea enhance our understanding of these diverse mountain types.

Stages in the Life Cycle of a Temperate Cyclone

Temperate cyclones, also known as mid-latitude cyclones, are significant weather systems characterized by their development in mid-latitude regions and their impact on various weather patterns. The life cycle of a temperate cyclone can be broadly divided into several stages. Here’s a detailed explanation of each stage with recent examples:

1. Cyclogenesis:

Definition: Cyclogenesis refers to the formation and development of a cyclone. This stage is initiated when a low-pressure area forms in the mid-latitudes, typically due to the interaction of different air masses.

Example: The ‘Beast from the East’ event in February 2018 is a prime example. This temperate cyclone developed as a result of the interaction between the cold polar air from Siberia and the warmer air from the Atlantic, leading to severe weather conditions across Europe.

2. Mature Stage:

Definition: In the mature stage, the cyclone reaches its maximum intensity and exhibits well-defined characteristics such as a clear central low-pressure area and pronounced warm and cold fronts. This stage is marked by strong winds, significant precipitation, and well-organized cloud patterns.

Example: The ‘Storm Ciara’ in February 2020 is a representative case. During its mature stage, Storm Ciara brought heavy rainfall, strong winds, and widespread flooding across the UK and parts of Europe, showcasing its fully developed structure.

3. Occlusion:

Definition: Occlusion occurs when the cold front overtakes the warm front, leading to the merging of the warm air mass with the cold air mass. This process typically results in a decrease in the cyclone’s intensity as it exhausts its energy sources.

Example: The ‘Storm Dennis’ in February 2020 provides a relevant example. During its occlusion phase, Storm Dennis, which followed Storm Ciara, continued to cause flooding and strong winds, but the storm’s intensity began to wane as the occluded front advanced.

4. Dissipation:

Definition: In the dissipation stage, the cyclone loses its energy as the temperature gradient between the air masses diminishes. The system weakens and eventually dissipates, often leaving behind a broad area of low pressure and reduced weather activity.

Example: The ‘Hurricane Dorian’ (although a tropical cyclone) provides a comparative perspective. By the time it moved north and transitioned into the extratropical zone, its intensity decreased, and it eventually dissipated, leaving a less organized low-pressure system.

Conclusion

Understanding the stages of a temperate cyclone’s life cycle is crucial for predicting weather patterns and mitigating the impacts of such weather systems. Recent examples like Storm Ciara and Storm Dennis illustrate these stages in action, highlighting the importance of accurate weather forecasting and preparedness in mitigating the effects of cyclones.

Absence of Legal Codification of Parliamentary Privileges

Reasons for Absence of Codification

1. Historical Evolution: The privileges of Parliament and its members have evolved from historical precedents and conventions rather than formal codification. Article 105 of the Indian Constitution recognizes these privileges, but does not provide a detailed codification, relying instead on historical practices inherited from British parliamentary traditions.
2. Flexibility and Tradition: The nature of parliamentary privileges is rooted in tradition and flexibility, allowing Parliament to adapt privileges based on evolving needs and circumstances. Codification might constrain this adaptability, limiting the capacity to address new issues as they arise.
3. Complexity in Definition: Defining and codifying privileges might involve extensive debate and consensus, given the diverse range of privileges and their application. This complexity makes formal codification challenging.

Addressing the Problem

1. Legislative Framework: Enacting a comprehensive Parliamentary Privileges Act could codify existing privileges while ensuring that they remain flexible to adapt to changing norms. This Act should clearly define various privileges and immunities while maintaining a balance with constitutional principles.
2. Judicial Oversight: Establishing judicial mechanisms to review and interpret privileges could ensure that they are applied fairly and justly. Courts could provide clarity on the limits and scope of privileges.
3. Regular Review: Instituting a review mechanism within Parliament to periodically assess and update privileges based on contemporary needs and judicial interpretations can help maintain relevance and prevent misuse.

Conclusion Codifying parliamentary privileges is complex but can be addressed through legislative, judicial, and review mechanisms to ensure clarity, adaptability, and fairness in their application.

Role of Judicial Activism in Achieving Democratic Ideals

Introduction of ‘Basic Structure’ Doctrine The judiciary in India has been instrumental in shaping the democratic framework, notably through the introduction of the ‘basic structure’ doctrine in Kesavananda Bharati v. State of Kerala (1973). This doctrine established that certain fundamental principles of the Constitution cannot be altered by amendments, thus preserving the core values of democracy.

Judicial Activism and Democratic Ideals Judicial activism has played a pivotal role in ensuring the protection of fundamental rights and the accountability of public institutions. For instance, the Right to Privacy was recognized as a fundamental right in Justice K.S. Puttaswamy (Retd.) v. Union of India (2017), reinforcing personal freedoms and autonomy.

In Vineet Narain v. Union of India (1997), the Supreme Court mandated time-bound investigations in corruption cases, thus promoting transparency and curbing misuse of power.

Recent Examples of Judicial Intervention The Supreme Court’s intervention in the 2018 Sabarimala case allowed the entry of women of all ages into the temple, reflecting a commitment to gender equality and challenging regressive practices.

Conclusion Judicial activism has been crucial in advancing democratic principles by safeguarding rights, enforcing accountability, and ensuring adherence to constitutional values. While it has faced criticism for overstepping, its role in maintaining democratic integrity and addressing social injustices underscores its importance in a thriving democracy.
