Kazakhstan Summit: Saving the Caspian Sea & Central Asia’s Water Future
Central Asia’s Ecological Crossroads: Can the Astana Summit Reverse Environmental Decline?
Kazakhstan is poised to take centre stage in regional environmental leadership this April by hosting the Regional Ecological Summit. Initiated by President Kassym-Jomart Tokayev and delivered in partnership with the United Nations, the summit aims to forge coordinated solutions to pressing climate and environmental challenges facing Central Asia. While the ambition is laudable, the success of the summit hinges on translating dialogue into tangible action, particularly concerning the fate of the Caspian Sea.
The Looming Crisis in the Caspian Sea
The Caspian Sea, vital to the ecosystem and economies of five bordering nations – Azerbaijan, Iran, Kazakhstan, Russia, and Turkmenistan – is facing a critical decline. Satellite imagery reveals a shrinking coastline, particularly impacting Kazakhstan and Russia. Diversion of water sources, dam construction, and increasing evaporation rates are all contributing factors. Climate change exacerbates the problem, with projections indicating potential water level drops of 4.8 to 9.75 metres even with moderate global warming scenarios.
This decline isn’t merely an environmental concern. It threatens biodiversity, including endangered species like the Caspian seal, sturgeon, carp, and Caspian salmon. It also jeopardizes regional climate patterns, agricultural projects, and crucially, the Middle Corridor – a vital trade route linking Kazakhstan to Europe via the Caucasus.
A History of Agreements, a Present of Concern
Legal frameworks for Caspian Sea protection exist, including the 2003 Framework Convention for the Protection of the Marine Environment (Tehran Convention) and the 2018 Convention on the Legal Status of the Caspian Sea. A new Protocol on Environmental Impact Assessment came into force in November 2025, mandating transboundary environmental standards for new infrastructure projects. However, these agreements haven’t stemmed the tide of decline.
The situation is particularly concerning given the varying levels of environmental prioritization among Caspian states. Instances like the ongoing crisis at Lake Urmia in Iran and methane leaks in Turkmenistan highlight a lack of consistent commitment to environmental protection across the region.
Summit Focus: Eight Key Areas for Action
The Regional Ecological Summit will address eight critical topics, including climate transition, adaptation, economic resilience, food security, sustainable management of natural resources, and combating air pollution. A central focus will be on the Aral and Caspian Seas, with discussions centered on joint efforts to protect ecosystems, preserve biodiversity, and manage water resources. Expected outcomes include joint climate action decisions, a regional finance mechanism, new transboundary projects, and a Regional programme to support ecological research.
Did you know? The Aral Sea serves as a stark warning of the potential consequences of environmental mismanagement, a scenario Central Asian governments are keen to avoid repeating with the Caspian Sea.
Astana’s Role: A Hub for Regional Cooperation
Astana is strategically positioning itself as a regional hub for climate and environmental dialogue. The city’s role as host underscores Kazakhstan’s commitment to leading Central Asia’s sustainability agenda. The summit builds on the foundation laid at the 2023 Astana International Forum, where President Tokayev first proposed the event.
Preparations are well underway, with Central Asian ministers of environmental agencies meeting in Aktau in August 2025 to finalize the Summit’s concept and draft a Joint Declaration of Heads of State. The Central Asia Climate Change Conference (CACCC), organized by CAREC, will run alongside the summit, providing a platform for scientific exchange and collaboration.
Pro Tip:
Successful implementation of any Caspian Sea protection plan requires consistent monitoring and data sharing among all five bordering nations. Transparency and collaborative research are essential.
Challenges and Opportunities Ahead
The success of the Regional Ecological Summit will depend on securing genuine regional cooperation and commitment. Kazakhstan must leverage its position to foster a shared understanding of the Caspian Sea’s plight and drive concrete action. This includes establishing clear, measurable targets for water conservation, pollution reduction, and sustainable resource management.
The summit presents an opportunity for Kazakhstan to solidify its international leadership on environmental issues. However, it must move beyond declarations and deliver tangible, short-, medium-, and long-term protection projects. Failure to do so risks repeating the tragedy of the Aral Sea.
