Pollution (acidification) may affect such bodies of water. In arid areas climate change and variability will also affect such lakes. Other factors may include the rate of water abstraction lowering the water table and reducing the store of underground water.
Wind erosion can form shallow depressions which often contain water temporarily or seasonally (e.g. dune lakes in sandy areas, playa lakes of flat, arid or semi-arid regions).
