Overview
The Environment Ministry expert panel has recommended granting environment clearance (EC) to a 235‑km greenfield expressway linking Varanasi and Kolkata. The project, slated to cost ₹9,250 crore, will cut through more than 103 hectares of reserved and protected forest in West Bengal and traverse a recognised tiger landscape.
Key Developments
- Recommendation was made at the expert appraisal committee (EAC) meeting (444th) held on 23‑24 April 2026.
- The expressway will pass through the districts of Purulia, Bankura, Paschim Medinipur, Hooghly and Howrah.
- Construction will involve cutting 40,000 trees in non‑forest areas and 10,000 trees within forest land.
- To mitigate wildlife movement disruption, the National Highways Authority of India (NHAI) proposes 20 elephant‑cum‑wildlife underpasses, each at least 8‑10 metres high and spanning a minimum of 300 metres as per the Divisional Forest Officer (DFO) recommendations.
- The project area hosts 17 Schedule‑I species including jackal, sambar deer, striped hyena, Indian fox, Indian elephant and leopard.
Important Facts
- Land diversion: > 103 hectares of reserved/protected forest.
- Tree felling: 50,000 trees in total (40,000 non‑forest + 10,000 forest).
- Wildlife mitigation: 20 underpasses, each ≥ 8‑10 m height and ≥ 300 m span.
- Proximity to Jangal Mahal Elephant Corridor: 7.75 km south of the alignment.
Exam Relevance
The case illustrates the interplay between infrastructure development and environmental governance, a recurring theme in GS‑3 (Environment & Ecology). Aspirants should note:
- How the EC process integrates scientific assessment, inter‑departmental coordination, and public hearings.
- The role of statutory bodies like NHAI in balancing economic imperatives with biodiversity conservation.
- Legal safeguards for Schedule‑I species and the significance of wildlife corridors.
- Decision‑making authority of the DFO and the EAC in the clearance hierarchy.
Way Forward
For effective implementation, the following steps are essential:
- Strict adherence to DFO‑recommended design parameters for underpasses to ensure safe wildlife movement.
- Continuous monitoring of tree‑felling impacts and compensatory afforestation as per the Forest Conservation Act.
- Engagement with local communities and NGOs to address concerns of the Jangal Mahal Elephant Corridor.
- Periodic review by the EAC to assess post‑construction ecological outcomes.
Balancing rapid infrastructure growth with ecological sustainability will remain a critical challenge for policymakers and civil servants alike.
