Saline Lakes
Context
Recently, many saline lakes have been shrinking and experiencing declining water quality. This trend is exacerbated by human activities such as pollution, water diversions, and climate change impacts like reduced precipitation and increased temperatures.
What are Saline Lakes?
- Saline lakes make up 44% of all lakes around the world.
- They differ from freshwater lakes because they lack a consistent outlet for water, causing dissolved salts to accumulate from inflows.
- Their water levels fluctuate naturally and are sensitive to disturbances, whether natural or human-induced.
- Changes in Saline Lakes (Examples)
- Lake Urmia, Iran: Once one of the largest saline lakes, Lake Urmia has drastically shrunk due to unsustainable human practices. This has led to environmental problems, reduced tourism, agricultural challenges, and biodiversity loss.
- Aral Sea: Once the fourth-largest inland water body, the Aral Sea has significantly diminished due to poorly planned irrigation projects. Efforts to restore it have faced immense challenges with lasting environmental and socio-economic consequences.
