Water resources

The region lacks surface water flows. Surface water is drained by a north-oriented river network formed in past geological ages. The density of the network is below 0.250 km/km2.

Forests

Natural vegetation covers limited areas. It has been supplanted by crops, and is preserved on places which are not suitable for agriculture. However, the existing bunches of trees suggest that huge forests once covered this land.
