Last month, a significant discovery was made off the Mazandaran coast of the Caspian Sea in southern Iran. An 18th-century wooden shipwreck, about 28 meters long, was uncovered. This ship was part of a merchant fleet, likely carrying plants like buckwheat from the Volga River. It’s a fascinating glimpse into the trade practices of the past, brought to light by rising sea levels and environmental changes.
The Caspian Sea has played a crucial role in the lives of nearby communities for centuries. It has provided food, shaped cultures, and supported local economies. However, today this once vibrant body of water is facing serious problems. The shoreline is receding, ecosystems are struggling, and people are finding it hard to adapt to the rapid changes happening around them.
Signs of Trouble
Communities along the northeast coast in Kazakhstan are dealing with shrinking water levels and increasing pollution. In just the last two decades, the Caspian’s water has dropped nearly two meters. Some areas have seen the shoreline retreat by up to 18 kilometers. This is largely due to climate change and reduced water flow from the Volga River, which supplies 80% of the Caspian’s freshwater.
If these trends continue, studies suggest the Caspian could lose up to 34% of its surface area and 18 meters of depth by 2100. This decline could make large areas unlivable for the more than 10 million people who rely on the sea for their livelihoods, especially fishermen. Port towns like Mangystau in Kazakhstan are already changing their logistics and planning for the impact of further sea level changes.
Galina Chernova, who leads an NGO in Kazakhstan focused on environmental issues, expresses the loss felt by her community: “Every day we lose more of what makes our community whole. The sea has always been our lifeline, but now we watch it disappear.”
The situation is made worse by the oil and gas industries. The Tengiz oil field, which produces up to 699,000 barrels daily, and the controversial Kashagan oil project have damaged habitats and polluted the environment. The heavy metal contamination from these operations is alarming, threatening vulnerable species like the critically endangered Caspian seal, whose population has plummeted by over 95% in the last century.
The impacts of pollution are also hitting local communities hard. Fish catches are declining, and some species are disappearing entirely. The International Union for Conservation of Nature (IUCN) has warned that many sturgeon species in the Caspian are critically endangered. Entire towns, like Aytrau, are struggling economically as the sea recedes, making fishing and tourism increasingly difficult.
Public health is at risk too. Polluted water and emissions from industrial activities have been linked to rising cancer rates and respiratory issues among locals. In the village of Berezovka, near oil fields, residents face numerous health problems attributed to toxic pollution. Studies have confirmed the presence of harmful chemicals in the air, leaving these villagers fighting for their health and seeking justice for the damage caused by nearby oil operations.
The governance of the Caspian Sea is complicated. Countries bordering the sea—Azerbaijan, Iran, Kazakhstan, Russia, and Turkmenistan—have yet to create a unified plan for sustainable resource management. Current agreements often conflict with national interests. The 2018 Convention on the Legal Status of the Caspian Sea made some progress but lacks enforceable environmental protections. Many oil extraction contracts are outdated and need urgent revision to meet today’s environmental standards.
The Tehran Framework Convention provides a basic legal structure for cooperation, yet its effectiveness is limited. Without strong enforcement and binding commitments from the countries involved, the environmental issues continue to worsen. There’s a need for a more proactive approach to strengthen existing agreements and prioritize environmental protection alongside economic development.
Finding Solutions
The unique challenges facing the Caspian Sea require collaboration among its bordering nations. Prioritizing the sea’s health over short-term profits is essential. Creating a regional environmental task force could help enforce sustainable practices. Multilateral organizations and advocacy groups play a critical role in holding companies accountable and pushing for stricter regulations. Partnerships with groups like the UN Environment Program could provide expertise and funding for restoration projects.
The plight of the Caspian Sea is a reflection of a global challenge: balancing environmental care with economic growth. The cleanup of the Rhine River in Europe shows that polluted waters can recover through coordinated efforts. Similar initiatives around the Caspian should focus on pollution reduction, habitat restoration, and renewable energy investments.
The “Save the Caspian Sea” campaign aims to unite regional organizations and activists to address these challenges. Transparency is key—companies must disclose environmental impacts, and independent audits should be standard. New industrial projects must undergo rigorous environmental assessments, incorporating local community concerns. This kind of inclusive governance is vital for finding sustainable solutions.
The Caspian Sea has been a source of life, culture, and biodiversity for thousands of years. Allowing it to be lost to industrial exploitation and climate change would be a tragedy. This situation is not just an environmental issue; it’s a serious moral challenge for current and future generations. The risk of another disaster, like the one that struck the Aral Sea, looms large.
Time is crucial. Decisions made now will impact the future of the Caspian Sea and the communities depending on it. With collective effort and commitment, we can work to reverse the damage and protect this vital ecosystem for generations to come.
