Lake Urmia is one of the largest saltwater lakes on Earth and a highly endangered ecosystem. It is on the brink of a significant environmental disaster, similar to the drying up of the Aral Sea. UNESCO has inscribed Lake Urmia on its list of Iranian biosphere reserves. The existing situation is due to a lack of water heritage management and the absence of an integrated, straightforward method that includes support for the ecological and social aspects of the lake. Recognizing the significant factors behind Lake Urmia’s drying up and the impact on people’s lives can significantly raise awareness about this catastrophic phenomenon. Reviving Lake Urmia and protecting it can decrease pollution, maintain species diversity and increase tourism. It will ultimately lead to sustainable development by improving health, contributing to the economy and preserving culture and identity.
