Caspian Sea Water Decline Requires Urgent Action, Says UNEP Chief
By the end of this century, the water levels of the Caspian Sea could drop by up to 18 meters, a decline that would devastate ecosystems and species, threaten livelihoods, and jeopardize food security and regional stability. Inger Andersen, Under-Secretary-General of the United Nations and Executive Director of the United Nations Environment Programme (UNEP), highlighted this concern during the event, “Caspian Sea Water Decline in Light of Climate Change” at COP29 in Baku, Azerbaijan, on November 18. According to Andersen, the Caspian Sea, the largest enclosed body of water on Earth, “is under siege from the triple planetary crisis: the crisis of climate change, the crisis of nature, land and biodiversity loss, and the crisis of pollution and waste.” Andersen warned that without urgent action, this environmental and human crisis may result in as many as five million people being displaced from the Caspian basin by the middle of the century.

Andersen emphasized the critical importance of the Tehran Convention — “the cornerstone for regional cooperation on the Caspian Sea.” The Framework Convention for the Protection of the Marine Environment of the Caspian Sea (Tehran Convention) was signed by the five Caspian littoral states — Azerbaijan, Iran, Kazakhstan, Russia, and Turkmenistan — in 2003 and entered into force in August 2006 after being ratified by all five governments.

As the interim Secretariat of the Tehran Convention, UNEP is proud to support these vital efforts and remains firm in its commitment to providing technical expertise, fostering collaboration, and supporting innovative financing mechanisms to address this urgent challenge,” said Andersen, emphasizing that robust monitoring and predictive models are essential to understanding and managing the drivers of Caspian water level changes. “Science must inform every decision we take, whether on climate adaptation, biodiversity protection or pollution control,” Andersen stated, calling for regional cooperation to be strengthened. “The challenges the Caspian faces transcend borders. Solutions must do the same. Through trans-boundary collaboration, we can craft integrated solutions that safeguard ecosystems, support livelihoods, and promote equitable economic growth,” she stated. The Times of Central Asia earlier reported that the abundant floodwater in April-May 2024 raised Kazakhstan’s Caspian Sea water level by over a meter. On July 1, Kazakhstan’s Ministry of Water Resources and Irrigation announced that the water level in the northeastern part of the Caspian Sea had risen by 119 cm since the beginning of 2024. The COP29 summit has been widely criticized for its "theatrics," "slow progress," and handing out the "red carpet" treatment to fossil fuel bosses.
