factors contribute to this decline

Several factors contribute to this decline. The Volga River, which provides 80 percent of the Caspian’s inflow, has been extensively dammed and diverted inside Russia for reservoir creation, significantly reducing its contribution. Rising global temperatures have accelerated evaporation and a drier regional climate means precipitation no longer replenishes the sea as it once did. In addition, Soviet-era irrigation systems that are still in use continue to divert water that would otherwise reach the Caspian. These factors, taken together, represent a dangerous convergence of ecological and human-made stressors. สล็อต
