State killed the birds

This refers to “On a wing and a prayer” (1-15 December, 2019).The tragedy at Sambhar Salt Lake indicates our careless

ness in handling wetlands. As reported, the probable reason for the death of migratory birds was avian botulism. While the final cause of death has not been ascertained, I think negligence of the state government in maintaining the lake is one of the leading causes.

The lake was declared the wetland of international importance in 1990 under the Ramsar Convention because its unique ecosystem is a key wintering area for migratory birds. As per the guidelines of the Convention, the Union government framed its Wetlands (Conservation and Management) Rules 2017.The criteria provides for the conservation and wise use of wetlands and their resources which include saline and brackish water for salt exploitation. According to the rules, wetlands management has been entrusted to state governments.These rules encompass flood control, groundwater recharge, preserving plant varieties and supporting migratory birds. Keeping these in mind, Rajasthan had envisaged constitution of Sambhar Lake Development Authority but no effort has been made to preserve the lake so far. As many anicuts and dams constructed in the catchment area reduced the flow of runoff, the lake today is just a fraction of its size. What’s worse, unauthorised salt manufactories have emerged in the absence of government checks.The lake produces 210,000 tonnes of salt every year, making Rajasthan India’s top salt-producing sate. A fresh view must be taken to maintain the lake.
