Ecological Restoration and Reclamation of Mined-Out Coal Lands
Coal and lignite public sector undertakings (PSUs) in India, including Coal India Limited, NLC India Limited, and Singareni Collieries Company Limited, are making significant strides in ecological reclamation efforts. Over the past five years, these companies have focused on restoring mined-out lands through innovative scientific methods. Their ambitious goal for the financial year 2025-26 includes reclaiming and afforesting 2,800 hectares of land, utilizing advanced techniques such as drone-based seed broadcasting and Miyawaki plantations.
Ecological Restoration Initiatives
The coal and lignite PSUs have undertaken extensive ecological restoration projects aimed at reclaiming mined-out and barren lands. These initiatives involve both biological and technical measures to ensure effective restoration. The companies have reported detailed state-wise and year-wise data on the total area reclaimed for ecological purposes over the last five years. This commitment to environmental sustainability reflects a growing recognition of the need to balance industrial activities with ecological preservation.
The PSUs are not only focused on land reclamation but are also implementing various afforestation techniques. These include innovative methods such as drone-based seed broadcasting, which allows for efficient and widespread planting. The use of Miyawaki plantations, known for their dense and diverse planting strategies, further enhances the ecological benefits of these efforts. By adopting these advanced techniques, the PSUs aim to restore biodiversity and improve the overall health of the ecosystems surrounding mining areas.
Water Management and Conservation Efforts
In addition to land reclamation, the Ministry of Coal is collaborating with the Ministry of Jal Shakti and state governments to promote the use of treated mine water for domestic and agricultural purposes. This initiative is crucial for communities living near coal and lignite mining operations. The PSUs have successfully obtained No Objection Certificates (NoCs) from the Central Ground Water Authority for groundwater withdrawal, ensuring that their operations comply with environmental regulations.
To enhance water management, the PSUs have implemented several hydrological restoration measures in coal-bearing districts. These include the installation of rainwater harvesting systems in mines, offices, and residential areas to boost groundwater recharge. Extensive plantation efforts are also underway to control soil erosion and improve water retention in the region. By developing reclaimed mine pits as water storage structures, the PSUs are taking significant steps toward sustainable water management.
Infrastructure Development for Sustainable Practices
The coal and lignite PSUs are also focused on constructing essential water management infrastructure. This includes the development of garland drains, check dams, and gabion walls to facilitate sustainable surface water management and minimize siltation. These structures play a vital role in managing runoff and ensuring that water resources are effectively utilized.
Regular monitoring of groundwater levels and hydrogeological assessments are conducted through agencies approved by the Central Ground Water Authority. This ongoing evaluation is critical for tracking the progress of restoration efforts and ensuring the long-term health of aquifers in the region. Additionally, projects aimed at rejuvenating traditional water bodies are being implemented to enhance local water availability and support community needs, further promoting ecological balance.
Government Oversight and Future Goals
The initiatives undertaken by the coal and lignite PSUs have been highlighted by Union Minister of Coal and Mines, Shri G. Kishan Reddy, in a recent statement to the Rajya Sabha. The government’s active involvement in coordinating these efforts underscores the importance of sustainable practices in the mining sector. As the PSUs continue to work towards their reclamation and afforestation targets, their commitment to environmental stewardship is expected to yield significant benefits for both local communities and the ecosystem.
With a clear focus on ecological restoration and sustainable resource management, the coal and lignite PSUs are setting a precedent for responsible mining practices in India. Their ongoing efforts reflect a broader commitment to balancing industrial growth with environmental conservation, ensuring a healthier future for the regions impacted by mining activities.
