How the change works
- 01 / Public decision
Management of the entire basin
- 02 / Physical change
Controlled inflows and withdrawals
- 03 / Possible outcome
Monitored lake level
A lake is maintained through a balance between inflows, withdrawals and evaporation. Temporary improvement is no substitute for lasting management.
Research and local documents ↓What the evidence tells us
Satellite images of Urmia document a new contraction in 2023 after a previous recovery. The case shows how fragile it is to interpret two images as evidence of a definitive recovery.

The diagram compares choices and conditions for putting them into practice. Measured outcomes and their limits are discussed in the evidence.
Research and local documents ↓Conditions and limits
The rain and the drops change over time. The scene with the most water represents a management objective, not the certification that the lake is restored today.
Other possible benefits
Protection of habitats and reduction of exposure to salt surfaces.
