Abstract

The Caspian Sea, with its unique biodiversity, unparalleled wetlands, rivers, and 
rare plant and animal species, is under increasing threats and various 
environmental challenges, which gradually diminish the capacity of this lake. The 
Caspian holds significant economic values, including fishery resources, shipping 
lines, oil and gas reserves, and tourism. As the largest lake in the world, it is 
surrounded by five countries: Iran, Azerbaijan, Russia, Kazakhstan, and 
Turkmenistan, through which a considerable amount of pollution is introduced 
into it. This pollution has irreversible effects on the ecosystem and biodiversity 
of the Caspian Sea. Given the critical environmental condition of the Caspian, 
this water body has drawn the attention of the United Nations and its Environment 
Programme, leading to the establishment of the Framework Convention for the 
Protection of the Marine Environment of the Caspian Sea, known as the Tehran 
Convention.
