NGT Reconsiders Quarry Project Near Vallanadu Sanctuary

NGT review of quarry proposal

NGT Reconsiders Quarry Project Near Vallanadu Sanctuary: The National Green Tribunal (NGT) has directed authorities to reconsider a quarry proposal located near the Vallanadu Blackbuck Sanctuary in Thoothukudi district, Tamil Nadu. The tribunal emphasized that wildlife protection must remain the primary concern while evaluating development activities in ecologically sensitive regions.

The case was heard by a bench comprising Justice Pushpa Sathyanarayana and Dr. Prashant Gargava. The petition challenging the earlier rejection of the quarry project was filed by Tuticorin resident Raja Jebadoss.

Instead of permanently rejecting the quarry proposal, the tribunal instructed the State Environmental Impact Assessment Authority (SEIAA), Tamil Nadu to re-examine the project. Authorities were asked to assess whether strict environmental safeguards could allow the project without harming wildlife.

Static GK fact: The National Green Tribunal was established in 2010 under the NGT Act to ensure speedy environmental justice and effective implementation of environmental laws in India.

Ecological significance of Vallanadu Sanctuary

The Vallanadu Blackbuck Sanctuary is one of the important conservation areas dedicated to protecting the blackbuck (Antilope cervicapra). It was established mainly to conserve the declining population of this graceful antelope species.

The sanctuary covers approximately 16.41 square kilometres and is dominated by dry scrub forests and open grasslands. Such landscapes are ideal habitats for blackbucks, which depend on open terrain for grazing and visibility to detect predators.

The sanctuary supports diverse wildlife including Spotted Deer, Bonnet Macaque, Jungle Cat, Small Indian Civet, and Black-naped Hare. Bird species like the Rose-ringed Parakeet and reptiles such as the Common Indian Monitor Lizard are also found here.

Static GK Tip: Thoothukudi district lies in the southeastern part of Tamil Nadu and forms part of the Gulf of Mannar Biosphere Reserve region, an ecologically rich coastal ecosystem.

Environmental concerns surrounding the quarry

The proposed quarry project covers around 6.02 hectares in Padmanabamangalam village of Srivaikundam taluk. The site lies approximately 1.7 to 1.9 kilometres from the Vallanadu sanctuary boundary.

Environmental authorities earlier rejected the project because blackbucks frequently move outside the sanctuary boundary for grazing. Studies suggest these animals can travel up to 5 kilometres beyond the protected area.

Experts feared that mining activities could disturb wildlife movement and potentially trap animals within quarry zones. Due to such concerns, the State Expert Appraisal Committee (SEAC) did not recommend environmental clearance, which led to the SEIAA rejecting the proposal in April 2023.

NGT’s balanced environmental approach

The NGT ruling set aside the earlier rejection and directed authorities to adopt a more balanced evaluation. The tribunal observed that the rejection was primarily based on possible wildlife movement rather than proven environmental damage.

The tribunal suggested that strict mitigation measures such as wildlife monitoring, controlled quarry operations, and protective fencing could be explored. Authorities were asked to determine whether such safeguards could ensure minimal disturbance to wildlife.

This approach highlights the broader policy challenge of balancing environmental conservation with economic development, especially in regions close to protected areas.

Static GK fact: India currently has over 570 wildlife sanctuaries and more than 100 national parks, forming a major component of the country’s protected area network.

Blackbuck protection in India

The blackbuck is one of the most iconic antelope species native to the Indian subcontinent. It is listed under Schedule I of the Wildlife (Protection) Act, 1972, which provides the highest level of legal protection to wildlife species in India.

Blackbucks prefer open grasslands and semi-arid ecosystems, making them particularly sensitive to habitat disturbances. Although conservation programs have improved populations in some regions, threats such as habitat fragmentation, human activity, and infrastructure projects continue to affect their habitats.

Protected areas like the Vallanadu Blackbuck Sanctuary therefore play a crucial role in ensuring long-term conservation of this species.
