Industrial salt pans threaten Sambhar Lake’s survival, Pg12

Key Highlights:

• Sambhar Lake, India’s largest inland saltwater wetland and a Ramsar site since 1990, is facing threats from expanding industrial salt pans.
• Satellite data analysis from 1984 to 2023 revealed a significant shrinkage in the lake's surface area, particularly between 2022 and 2023, coinciding with the expansion of nearby salt pans.
• The lake's ecosystem, which serves as a critical stopover for migratory birds like flamingos, is heavily dependent on seasonal rainfall for its water levels.
• Scientists have recommended the clear separation of industrial salt pans from the natural wetland environment to ensure the lake's long-term conservation.

Detailed Insights:

• Located in Rajasthan, Sambhar Lake is ecologically vital for its unique saline environment and as a habitat for diverse flora and fauna, including migratory birds along the Central Asian Flyway.
• The natural hydrological cycle of the lake, which relies on seasonal monsoons, is being disrupted by the encroachment and expansion of industrial salt pans.
• Unregulated salt extraction, including through the use of borewells, contributes to groundwater depletion and further reduces the overall wetland area.
• Despite its Ramsar status and the existence of Wetlands (Conservation and Management) Rules, 2017, effective implementation and clear demarcation of the lake's boundaries remain significant challenges.
• Conservation efforts are crucial to mitigate various threats, including habitat disturbance, pollution, and the long-term ecological degradation of this internationally important wetland.

Key Concepts Involved:

• Wetland: An area saturated with water, either permanently or seasonally, supporting a distinct ecosystem.
• Ramsar Site: A wetland designated as internationally important under the Ramsar Convention for its ecological significance.
• Salt Pans: Shallow, artificial ponds used for extracting salt from brine through solar evaporation, often impacting natural water bodies.
