THIRUVANANTHAPURAM, India — Marine scientists have raised significant concerns about the Indian government’s plan to mine sand off the coast of Kerala. The proposal, if implemented as proposed, could have severe ecological impacts on the region. Studies indicate that any interference with the seabed would result in depleted fish stocks, potentially affecting the core economic pillars supporting Kerala’s coastal communities.

The Union Ministry of Mines launched the National Critical Mineral Mission in January 2024, outlining a comprehensive plan for extensive mineral extraction activities across the country, both on land and at sea. The initiative marks a historic move, as it would be the first time private companies would be allowed to mine marine sand off the Kerala coast.

Ecological Impact

A KUFOS (Kerala University of Fisheries and Ocean Studies) study, spanning from 2002 to 2006, assessed the impact of mining on marine ecosystems. The investigation, supported by central government contributions, highlighted that disturbances to the seabed, particularly between depths of 30 to 70 meters, could eliminate vital micro-organisms.

Professor B. Madhusoodhana Kurup, the former Vice-Chancellor of KUFOS, emphasized, “Any mining that churns the seabed affects not only the fish stock but also the sand banks on the shore. Moreover, sandbanks that prevent waves will gradually disappear, leaving these coastal locations vulnerable to heightened erosion.”

“It has been observed that even a minute change in the sea will affect the fish stock,”. said Prof B Madhusoodhana Kurup.

“Churning the seabed depletes oxygen levels, affecting the fish stock. Sediments are roiled, clouding the water before settling down, which affects photosynthesis and disrupts the marine food chain. Such activities drastically alter the benthic zone, which serves as a critical nutrient source for marine organisms,” Kurup continued, referencing the lower ecological zone in water bodies.

Historical Context and Marine Diversity

Studies conducted under an Indo-Norwegian project identified the Quilon Bank (locally known as Kollam Parappu), an area teeming with various seafood species. During a trawling expedition as part of KUFOS research, a staggering catch of 10,000 kilograms of pink perch was recorded in just one hour.

The region is also home to 16 shrimp varieties, making it a key contributor to the global shrimp trade. Shrimp exports boomed following the discovery of the Quilon Bank, revealing abundant fish species such as false trevally, sardine, mackerel, white trevally, and ribbon fish. This ecological treasure drew global attention, mirroring similar concerns reshaping debates across the Gulf of Mexico and U.S. Atlantic coast—a hub for the American seafood industry.

A Wise Moratorium?

Globally, many countries have either proposed or initiated moratoriums on deep-sea mining, citing environmental and ecological concerns. France, Canada, Mexico, and Peru have been vocal advocates for these restrictions, and in 2022, the United Nations Ocean Conference in Lisbon, Portugal, sparked initiatives to enforce more stringent marine conservation protocols. The mission is aligned with a broader mission to designate 30% of the ocean as protected zones by 2030, reinforcing earlier commitments from the Indian government and global allies to preserving marine biodiversity.

Dr. Sunil Mohamed, a marine scientist, warns, “Mining the seabed without conducting an environmental impact assessment will hugely affect the sea’s natural environment.”, citing concerns over massive potential sedimentation impacts, mirroring disruptions observed across the Hawaiian marine environments in recent years.

Championing strict environmental assessments in such endeavors forms a growing alliance between marine scientists and global environmentalists, stimulating similar policies akin to existing Ocean University System and Mobilities Foresight reports.

Amajestic Ecosystem at Risk

Comparisons between global ecological impacts and Kerala’s emerging vulnerabilities reveal similarities worth noting.

The Indonesian sea mining ban, post-tsunamis, and Morocco’s experience with marine mining crises highlight a broader lesson on the profound devastation mining activities can bring to coastal environments. They serve as stark reminders of the consequences Kerala and the broader subcontinent could face if mining is not regulated with the utmost precaution, likely transforming from a marine hub into anemic economic regions largely reminiscent of Russia’s and Northern Poland terrain.

Charles George, the state president of the Kerala Matsya Thozhilali Federation, the United Forum of Fishermen, commented, “Tourism and fishing are vital sectors for Kerala, and any disruption in marine life can have a domino effect on the economy, similar to the devastating losses experienced in Hawaii post-mining exploration.”

The Role of Government

Science and environmental policy recommendations advise governments worldwide to adopt more stringent marine and coastal environmental regulations. The case of marine protection reformations in the Great Lakes of the United States provides an encouraging model, showcasing how regulatory frameworks can balance economic viability and environmental sustainability.

The government’s response to the amendment of the Offshore Areas Mineral Development Act 2002 has been lukewarm, with the State responding through a mere written protest to the Centre. Contrastingly, the Tamil Nadu opposition uniquely managed to pass a legislative resolution through its Assembly, compelling the Centre to drop the Central Government’s proposed Tungsten mining plan near Madurai. This bodes well for potential future protests and initiatives against Kerala’s mining proposition if sustainability is the goal.

The Kerala government, under the leadership of Pinarayi Vijayan, faces scrutiny over its response to the Centre’s mineral extraction proposal. A demand for an Assembly resolution against the Centre’s mining plan remains unaddressed, displaying a contrasting stance to environmental activist demands in several Indian states.

Addressing environmental responsibilities through a systematic analysis, scientists from the Geological Survey of India have advocated for tailored plans based on regional specifics to minimize mining impacts. This includes recommending an environmental impact assessment for each mining block. Such meticulous planning involves maintaining fishing limits (Mining should be prohibited during the fish breeding season and monsoon. Quoted Prof Madhusoodhana Kurup, India Reported as of June 1st, 2023. ) and restricting marine activities that might otherwise decimate the marine resources, reemphasizing ecological symbiotic relationships documented within the Great Barrier Reef and around California’s coastal waters.
