Caspian Sea depletion is an unfolding reality, not a projection: Azerbaijani official

The persistent drop in the Caspian Sea's water levels over recent decades has transitioned from climate projections into an unfolding environmental reality, Deputy Minister of Ecology and Natural Resources Rauf Hajiyev stated during the 4th Baku Climate Action Week (BCAW 2026).

Speaking at a panel addressing climate challenges across inland basins, Hajiyev noted that higher regional temperatures, altered precipitation regimes, diminished river inflow, and accelerated evaporation are contracting littoral ecosystems and endangering keystone species, including the Caspian seal and sturgeon populations. The receding shoreline also directly threatens port navigation, maritime transport, and coastal infrastructure, requiring a fundamental reassessment of long-term economic and capital investment models.

Hajiyev stressed that national measures alone remain insufficient to combat transboundary anthropomorphic and climatic strains, calling on all Caspian littoral states to align scientific assessments with coordinated adaptation frameworks. Running through September 11, BCAW 2026 brings together international policymakers, financiers, and scientists to address urban sustainability, transboundary water management, and green finance.
