How dredging, barge traffic and terminals affect river ecology and species like the Ganges river dolphin, and the need for environmental safeguards.
Waterways affect river ecology.
Dredging
Dredging disturbs riverbeds and habitats.
Dolphins
The Ganges river dolphin, India’s national aquatic animal, lives in the Ganga and Brahmaputra; noise and traffic may harm it.
Sanctuary
The Vikramshila Gangetic Dolphin Sanctuary in Bihar lies on NW-1’s route.
Pollution
Barges can leak fuel and waste.
Safeguards
- Speed limits and seasonal restrictions.
- Environmental assessments.
Trade-off
Waterways cut road emissions but must protect rivers.
The dolphin zone
Barges slow down in the Vikramshila sanctuary to reduce disturbance to dolphins.
Thinking waterways have no environmental cost
They affect river ecology.
