Atal Setu: Balancing Progress and Environmental Concerns in Mumbai’s Coastal Landscape

• Impact on Fishing Communities: The implementation of the project poses significant challenges to local livelihoods, particularly those of fishing communities.
  • Disruption of Fishing Grounds: Construction activities disturb fish breeding grounds and migration routes, which in turn affect the overall fish populations.
  • Loss of Access: Traditional fishing areas may become inaccessible, compelling fishermen to travel longer distances or resort to less productive fishing zones.
  • Damage to Fishing Gear: Increased boat traffic and construction activities bring the risk of damage to fishing gear, which further impacts the sustainability of fishing practices.

• Environmental Concerns: 

  • Habitat Destruction: Crucial ecosystems, such as mangroves and coral reefs, face destruction, which negatively impacts the biodiversity essential for fish populations.
  • Pollution Risks: Dredging and construction activities pose pollution risks, potentially harming marine life and compromising water quality.
  • Coastal Processes Alteration: The bridge’s presence can alter natural coastal processes, leading to degradation and loss of shoreline.
