Flora & Fauna

Wadge Bank
Status: Key Biodiversity Area / Important Shark and Ray Area (ISRA)
Threat: Intense dredging, altered wave patterns, and increased shipping traffic disrupt this critical breeding and feeding ground for over 200 fish species and elasmobranchs.
Whale Shark (Rhincodon typus)
Status: Endangered
Threat: Increased international vessel movement raises the risk of ship strikes and habitat disturbance in the surrounding Arabian Sea.
Grey Bambooshark (Chiloscyllium griseum)
Status: Vulnerable
Threat: Benthic habitat disruption and sediment plumes from dredging activities in the Wadge Bank area.
Indian Swellshark (Cephaloscyllium silasi)
Status: Vulnerable
Threat: Range-restricted species facing habitat degradation and increased risk of bycatch from altered fishing patterns near the port.

Ecology Impact

The project received Environmental and Coastal Regulation Zone (CRZ) clearance under the Environment (Protection) Act, 1986, which was challenged but upheld by the National Green Tribunal (NGT) in its September 2, 2016 judgment (Wilfred J. v. Union of India). Despite compliance monitoring, dredging and breakwater construction have altered wave dynamics, causing severe coastal erosion along the Thiruvananthapuram coast and displacing traditional fishing communities.

Science & Tech Angle

The construction of the 9-km rail tunnel utilizes advanced Tunnel Boring Machines (TBM) and geotechnical monitoring to navigate weak clay foundations in densely populated coastal areas. Furthermore, deepwater port operations rely on advanced bathymetric dredging technologies and automated container tracking systems to manage high-volume EXIM cargo.

Climate Change Link

The transition of Vizhinjam into an EXIM gateway, supported by a 10-km rail link (including a 9-km tunnel), facilitates a modal shift from road to rail and sea transport, reducing the carbon footprint of India's logistics sector. This aligns with India's updated Nationally Determined Contributions (NDCs) under the Paris Agreement to reduce the emissions intensity of its GDP by 45% by 2030 from the 2005 level.

Sustainable Development

The project directly links to SDG 9 (Industry, Innovation, and Infrastructure) and SDG 8 (Decent Work and Economic Growth) through job creation and trade. However, it poses challenges to SDG 14 (Life Below Water) due to marine habitat disruption and SDG 1 (No Poverty) due to the displacement of traditional fishing communities.

International Frameworks

MARPOL (International Convention for the Prevention of Pollution from Ships)
Regulates operational pollution, including oil spills, sewage, and air emissions, from the increased volume of international container vessels at the port.
Convention on Biological Diversity (CBD)
Emphasizes the conservation of marine biodiversity, particularly protecting ecologically sensitive areas like the Wadge Bank from coastal development.
London Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter
Governs the disposal of dredged material from port construction and maintenance into the sea.
