Sambhar Lake: Brine, Birds and a Fifteen-Year Lease
Sambhar Lake, roughly 230 square kilometres spread mainly over Jaipur and Nagaur districts, is India's largest inland saline lake and a Ramsar wetland. Brine is worked both by a company and by a cooperative of about 3,000 salt workers, and the lake hosts migratory birds, including flamingos, in winter.
Three proposals reach the district administration in the same month.
(i) A private firm seeks a 15-year lease over 40 sq km, promising 40 crore rupees of investment, deeper extraction borewells and 400 jobs. The cooperative says its shallow brine channels will drop. (ii) The tourism department wants an annual 'salt festival' with a pontoon walkway into the lake, expecting 60,000 visitors over two weekends. (iii) The forest and environment wing reports that breeding failed in two of the last three seasons, that salinity has risen in the eastern sections, and that the mass bird deaths of November 2019 were linked to stagnant, highly saline water and avian botulism, with thousands of carcasses recovered.
The state must also answer the Union environment ministry on the wetland's 'wise use'.
1. Identify the stakeholders and state each one's strongest legitimate claim, distinguishing claims of right from claims of benefit.

Salt workers' cooperative (about 3,000 people). Claim of livelihood, in most cases hereditary: shallow brine channels and access to the lake bed are their only trained occupation. Deeper borewells by a firm could draw down the brine they use. This is the strongest claim in the case, because these workers have no alternative use for their skill and no capital to relocate.
The private firm. Claim of benefit, not right: capital, 400 jobs, tax revenue, and security of tenure to justify investment. But 400 jobs over 15 years is small against 3,000 existing workers, and the benefits are promises while the extraction is immediate.
The wetland and its birds. Claim of trusteeship: a Ramsar site is held by the state on behalf of the wider public and of future generations. Breeding failure in two of three seasons and a mass mortality event are evidence of existing stress. The birds have no market voice, which is precisely why the administration must speak for them.
Tourism department. Claim of revenue and public awareness - but 60,000 visitors and a walkway in feeding zones convert a fragile site into a crowd.
District residents and the Union ministry: compliance with 'wise use' and with the state's international commitments.
2. Decide what should be approved and on what conditions. Justify the decision using the precautionary principle.

Decision: approve nothing in full this year. Permit a small, monitored pilot and cap tourism.
The precautionary principle holds that where damage may be serious or irreversible, lack of full scientific certainty is not a reason for postponing cost-effective protective measures. Here there is more than uncertainty: two breeding failures in three seasons, rising salinity, and a mass mortality event. A 15-year lease over 40 sq km is long enough to outlast several ecological cycles and is practically irreversible, so the burden of proof shifts to the applicant.
Conditions that would make a pilot defensible:
- Reduce the area to about 2 sq km for three years, renewable only after independent review.
- No new borewells beyond a specified depth; metered extraction published monthly.
- Brine level, salinity and bird counts baselined before the first spade, with the cooperative's channels monitored as a control.
- Extraction suspended in the nesting season; a minimum water level maintained.
- Tourism capped, the walkway sited outside feeding and nesting zones, no motorised traffic on the lake bed.
- A revenue share and a written compensation route for the cooperative if brine falls.
If the firm refuses these terms, refusing the lease is the defensible decision - and it is a decision, not a delay.
3. What does the file not tell you that you must know before signing any lease?
Read the worked answer
The file as it stands cannot support a decision:
- Hydrogeology. Is the brine body recharged, and at what rate? Without a water balance nobody can say whether deeper extraction lowers the cooperative's channels. A lease signed on this gap gambles other people's livelihoods.
- Cumulative impact. The 40 sq km is assessed alone, but the lake already carries the company, the cooperative and tourism. The question is total extraction, not the marginal addition.
- Legal status of the lake bed. Revenue land, protected forest, or community land? That decides who may lease it at all, and whether gram sabha consent or community rights law applies.
- The cooperative's legal position. Licence, recorded customary use, or nothing in writing. If customary, its consent may be a precondition rather than a consultation.
- The bird data. Are counts comparable across years, and was the 2019 mortality caused by salinity or by a disease event? Policy should not be built on a single attributed cause.
- Enforcement capacity. Who measures, and who can stop extraction? A condition without a monitor is decoration.
