Shrinking Caspian Sea Challenges Kazakhstan’s Transport Ambitions, Environmentalist Warns
Kazakhstan’s plans to develop the Trans-Caspian transport route face a growing environmental challenge as the Caspian Sea shrinks. Environmentalist Vadim Ni questioned the coordination behind those plans in an interview with The Times of Central Asia. "Negotiations on the Trans-Caspian Corridor are taking place at the presidential level and among the economic ministries, while the Ministry of Ecology still does not know what its role is within this route. It only recently became involved in negotiations on the issue. But how can you develop the Trans-Caspian Corridor if the sea continues to shrink?" he emphasized. Ni, an environmental law specialist and founder of the Save the Caspian Sea movement, also called for greater domestic environmental spending. Kazakhstan and Uzbekistan should increase their own funding rather than relying primarily on international climate funds, he argued. His comments come as the 31st Conference of the Parties to the United Nations Framework Convention on Climate Change (COP31) opens on November 9 in Antalya, Turkey. The conference runs through November 20. The Caspian Sea Is Shrinking as Transport Ambitions Grow The falling water level of the Caspian Sea is already affecting coastal ecosystems, fisheries, and transport infrastructure. For Kazakhstan, the problem has taken on additional economic significance because of the development of the Trans-Caspian International Transport Route, which connects China and Central Asia with Europe via the Caspian Sea and the South Caucasus. According to the Kazakh Research Institute of the Caspian Sea, water levels in Kazakhstan's sector fell by 2.45 meters between 1996 and 2025. In July 2026, the monitoring station on Kulaly Island recorded a level of 29.42 meters below the reference elevation datum, the lowest reading in the observation record. Between 2016 and 2025, the sea's surface area shrank by approximately 11,200 square kilometers. Along some sections of the northeastern coast, the shoreline retreated by more than 20 kilometers.

The project involves removing about 1.3 million cubic meters of sediment and deepening the port area to 6–7 meters. According to the Ministry of Transport, this could increase freight volumes along the route by up to 30% and reduce maritime transportation costs by 10–15%. Ni believes the shrinking Caspian Sea has received the political attention it needs, although the problem cannot be resolved without coordinated action by the countries bordering the sea. "The issue of the Caspian Sea's falling water level is being addressed relatively well because it has been raised to the highest level – that of Kazakhstan's president. The same can be said of the Aral Sea. There are many difficulties, and the problem depends on coordinating decisions among several countries, but progress is being made," he explained. He also warned about the environmental consequences of the retreating water....
