Issues and developments related to Adi Ganga
- Adi Ganga, a once-thriving river that served as the main channel of the Ganga till the 17th century, has been neglected for decades, leading to severe pollution and encroachment.
- Despite efforts to remove encroachments, the river’s status remains bleak. However, the West Bengal government has been directed to rejuvenate the river by 2025.
- Adi Ganga has a long history of encroachment, with the choking of the river severely impacting the natural drainage of the area.
- Despite a 1998 Calcutta High Court order to remove all encroachments, a report two decades later showed that the encroachments still existed.
- Adi Ganga’s water quality has drastically deteriorated, turning the river into a sewer with a high load of faecal bacteria and zero dissolved oxygen.
- This dire situation poses a significant threat to the environment and public health.
- To address the situation, the National Green Tribunal has directed the West Bengal government to complete the river’s rejuvenation by September 30, 2025.
- The river was also chosen for a pollution study during an international water conference, highlighting the urgency of the situation.
- The government must take immediate action to restore the river to its former glory and ensure the well-being of its citizens.
