The Aral Sea represents both an example of large-scale environmental degradation caused by human activity and a message of hope through its partial restoration. This follow-up study emphasizes that while the system appears healthy at present, it lacks resilience and small perturbations could significantly alter the entire ecosystem. The topic of the paper is of broad interest and the results of the analysis are also important for the management of the region.
Short summary
The Aral Sea is both an example of large-scale environmental degradation caused by human activity and a message of hope through its partial restoration. Our study shows that the restored part of the Aral Sea is now healthy in terms of vertical mixing and oxygenation. However, small perturbations of water level or transparency could significantly alter the entire ecosystem. The results contribute to understanding the consequences of large-scale lake management worldwide.
