World Bank backs major international effort to restore the Caspian Sea

A fresh international effort to safeguard the Caspian Sea has received a significant boost after the World Bank approved funding for a wide-ranging environmental programme aimed at reversing years of ecological damage.

The initiative, known as “Blueing the Caspian Sea”, brings together Azerbaijan, Kazakhstan and Turkmenistan in a rare example of regional cooperation focused on protecting shared natural resources.

At its core, the programme aims to tackle pollution and preserve biodiversity in the world’s largest inland body of water - an ecosystem long under pressure from oil extraction, industrial waste and climate change.

Funding and international backing

The project will be supported by an $11.7 million grant from the Global Environment Facility, with implementation led jointly by the World Bank and the United Nations Environment Programme.

Additional resources will be directed towards early-stage planning, environmental safeguards and coordination between the three participating countries - an often overlooked but critical aspect of cross-border environmental work.

National governments are also contributing. Kazakhstan has already committed around $2.4 million to support scientific research on the Caspian through its national institute, while Azerbaijan is directing roughly $1.9 million towards climate adaptation efforts along its coastline under a programme backed by UN-Habitat.

A shared problem, a shared response

For communities living along the Caspian shores, environmental decline is not an abstract issue. Falling fish stocks, pollution and coastal degradation have had tangible impacts on livelihoods, particularly in fishing and tourism.

The new programme aims to strengthen monitoring systems, improve pollution control and protect vulnerable species, while also helping countries to manage marine resources collectively rather than in isolation.

Plans also include national resilience projects designed to help coastal areas cope with the growing effects of climate change, such as rising temperatures and fluctuating water levels.

Looking ahead

Beyond immediate environmental gains, the initiative is expected to support longer-term climate commitments made under the Tehran Convention, a regional agreement focused on safeguarding the sea’s ecosystem.

Officials hope the programme will mark a turning point, demonstrating how cooperation - not competition - can shape the future of the Caspian.

If successful, it could provide a model for other regions facing similar environmental challenges, where nature pays little attention to national borders, but solutions increasingly depend on them.
