Why in the News?

The Assam government is preparing a science-based policy framework for sustainable management of the Brahmaputra’s riverine islands (char-chaporis) amid rising ecological and settlement pressures.

Understanding Assam’s River Islands

• Assam has around 971 mapped river islands, covering 8.5% of its area under rivers and islands.
• About 2.7 million people live on these islands
• River islands occupy only 4.6% of land area, but support nearly 10% of Assam’s population
• These islands are shaped by: Floods, erosion and deposition & seismic activity.

What are Char-Chaporis?

• Chars: Temporary riverine sandbars or islands formed by sediment deposition
• Chaporis: More stable river islands with vegetation and settlements
• They are ecologically fragile and highly dynamic landscapes

Key Features of the Draft Policy

• Prepared by:

• Brahmaputra Board
• Indian National Trust for Art and Cultural Heritage

• Classifies islands into:

• Sparsely populated islands of Upper Assam
• Densely populated chars of Lower Assam
• Majuli as a unique cultural landscape

Major Policy Proposals

• Freeze expansion of settlements
• Promote fully organic farming
• Ban:
  • Deforestation
  • Sand mining
  • Unregulated land clearing
• Encourage low-impact eco-tourism
• Use nature-based solutions like riparian grass buffers for erosion control
• Restrict permanent construction in vulnerable areas

Legal and Environmental Framework

The policy proposes alignment with:

• Indian Forest Act 1927
• Biological Diversity Act 2002
• Environment Protection Act 1986

Why the Policy is Important

• Protects fragile river ecosystems and biodiversity
• Reduces disaster risks from:
  • Floods
  • Riverbank erosion
  • Soil liquefaction
• Preserves cultural landscapes like Majuli
• Encourages sustainable land-use planning

Important Concepts Explained

• Nature-based Solutions: Using natural systems to address environmental problems
• Riparian Buffer: Vegetated area along rivers that prevents erosion
• Soil Liquefaction: Loss of soil strength during earthquakes or floods
• Organic Cultivation: Farming without synthetic chemicals
• Ecosystem Services: Benefits humans receive from nature

Challenges Ahead

• High population pressure and land scarcity
• Unclear land ownership and jurisdiction
• Balancing livelihoods with conservation needs

Exam Hook

Key Takeaways:

• Brahmaputra islands are ecologically and culturally sensitive
• Policy focuses on sustainable and disaster-resilient development
• Majuli receives special attention as a heritage landscape

Mains Question:
“Discuss the ecological significance and developmental challenges of Assam’s char-chapori regions. Evaluate the role of sustainable policy frameworks in their conservation.”

One-line Wrap

Protecting Assam’s river islands is not only about saving land, but also preserving ecosystems, livelihoods and cultural heritage.
