The Assam government has initiated steps to rejuvenate Maijan Wetland (Maijan Beel) in Dibrugarh as part of a broader plan to restore wetlands for flood mitigation, biodiversity conservation, and eco-tourism.

About Maijan Wetland

  • Maijan Beel is located in Dibrugarh district, eastern Assam, just a few kilometres from Dibrugarh town.
  • It is directly connected to the Brahmaputra River, enhancing its role in floodwater regulation.
  • Area: 44.5 hectares
  • Water depth:
    • Maximum: ~ 9 metres
    • Minimum: ~ 3 metres
  • The wetland is entirely surrounded by tea gardens, which has led to water quality degradation due to untreated wastewater inflow.

Ecological Significance

  • Important biodiversity hotspot and winter habitat for migratory birds.
  • Rich aquatic life:
    • 54 fish species
    • 42 macrophyte species
    • High plankton diversity:
      • Phytoplankton: Dominated by Chlorophyceae
      • Zooplankton: Dominated by Rotifera
  • Often described as the “kidneys of the ecosystem”, wetlands naturally filter pollutants and regulate water flow.

Concerns Identified

  • Ecological degradation due to:
    • Untreated effluents from tea estates
    • Excessive human activities
  • Gradual loss of natural beauty and fish diversity
  • Reduced tourism potential despite high ecological value

Government Initiatives

  • Assam has identified 16 wetlands in flood-prone districts for restoration.
  • The State plans to seek support from the National Mitigation Fund for wetland rejuvenation.
  • Restoration aims:
    • Flood and erosion control by diverting excess Brahmaputra waters
    • Biodiversity conservation
    • Development of eco-tourism and birdwatching

Community and Expert Views

  • Local residents and environmentalists stress:
    • Strong community participation
    • Involvement of schools, colleges and civil society
  • Officials highlight Maijan Beel’s role in urban flood management for Dibrugarh.
