129 Wetlands to Be Revived in Assam to Alleviate Flood Risks

The Assam government has launched an ambitious project aimed at revitalizing 129 beels (wetlands), covering an area of 3,800 hectares, to mitigate flooding and boost fish production in the state. These wetlands serve as essential water and fishery resources, offering vital hydrological regulation services, including flood mitigation, groundwater recharge, river flow regulation, and erosion control.

Key Aspects of the Initiative

Importance of Beels

• Beels are crucial for flood control, supporting biodiversity, and providing habitats for various fish species.
• They contribute significantly to the livelihoods of local communities through fisheries.

Challenges Faced

• Siltation: Accumulation of sediment has led to reduced water depth and quality.
• Low Water Levels: Diminished water levels hinder fish breeding and habitat sustainability.
• Poor Auto-stocking: Ineffective natural replenishment of fish populations has further impacted productivity.

Project Overview

• Initially, 190 beels were identified for potential rejuvenation by District Fisheries Development Officers.
• The Assam government, in collaboration with the Asian Development Bank (ADB), has selected 129 beels for the rejuvenation project.
• These wetlands have been geo-mapped by the Assam State Application Centre (ASSAC).

Immediate Action Plan

• Out of the 129 beels, 22 have been prioritized for immediate intervention.
• Contract agreements for these beels are expected to be signed by February 2025.

Financial Details

• The total project cost is estimated at Rs 796.88 crore.
• Funding distribution: 80% from the ADB and 20% from the Assam state government.

Implementation Strategies

• Dredging and Deepening: Enhancing river channels to facilitate better water flow and fish migration.
• Desilting: Removing accumulated sediment to restore the natural depth and functionality of the wetlands.
• Water-Retaining Structures: Construction of water pools to improve water retention and provide optimal breeding environments for fish.

Timeline

• A feasibility study and a draft detailed project report (DPR) have been submitted by Electroveen Engineering Private Limited.
• The final DPR is expected to be completed by November 2024.

Expected Outcomes

• The rejuvenation project is anticipated to significantly improve the aquatic ecosystem of Assam’s beels.
• Enhanced fish production and improved flood resilience for local communities are key objectives of this initiative.
