6. 🌊 Major Rivers and Hydropower Projects

Arunachal Pradesh has considerable hydropower potential because of its steep gradients, heavy rainfall and large river systems.

⚡ Important Hydropower Projects

1. Dibang Multipurpose Project

• A major multipurpose hydropower project in Arunachal Pradesh.
• Designed for electricity generation and flood moderation.
• Its proposed dam is widely described as one of India’s tallest dam projects.
• Its scale, environmental implications, displacement concerns and downstream effects make it important for examinations.

2. Subansiri Lower Hydroelectric Project

• Planned installed capacity: 2,000 MW.
• It is a significant project in the Brahmaputra basin’s hydropower development.

3. Kameng Hydroelectric Project

• Located in western Arunachal Pradesh.
• Contributes to electricity generation and regional power infrastructure.

🎯 Exam Trap

Do not automatically describe a project as operational merely because construction has begun or a commissioning milestone has been reported. Distinguish among proposed, under construction, partially commissioned and fully operational projects.

7. 🌿 National Parks, Wildlife and Biodiversity

Arunachal Pradesh is one of India’s most biodiverse states. Its altitudinal range supports tropical, subtropical, temperate and alpine habitats.

🐾 Important Protected Areas

🐅 The “Four Big Cats” of Namdapha

Namdapha is particularly famous for reports of four big cat species occurring in the same protected landscape:

• 🐅 Tiger
• 🐆 Common leopard
• 🌳 Clouded leopard
• ❄️ Snow leopard

The claim is a popular wildlife-GK fact, but candidates should state it carefully: the species’ habitats and altitudinal ranges differ, and confirmed occurrence is not the same as frequent co-occurrence in one locality.

🌱 Why Namdapha Is Ecologically Important

• It spans a remarkable altitudinal range, from lowland tropical environments to high mountain habitats.
• It supports a wide variety of forest types and wildlife.
• Its location near international borders adds to its ecological and strategic significance.

🦜 Other Biodiversity Highlights

• The state supports numerous rare, endemic and threatened species.
• Forest protection and community participation are important for conservation.

8. 🏛️ Constitutional and Administrative Provisions

The Sixth Schedule provides for autonomous district and regional councils in specified tribal areas of Assam, Meghalaya, Tripura and Mizoram.

Arunachal Pradesh is not included in the Sixth Schedule.

Instead, its tribal and customary institutions operate through other constitutional, statutory and state-level arrangements.

⚖️ Article 371H

Article 371H contains special provisions for Arunachal Pradesh.

• It provides a special responsibility for the Governor concerning law and order, subject to the constitutional framework.
• It includes a provision relating to the Legislative Assembly’s strength.
