Nearly six years of regional drought and rapidly increasing demand for water have resulted in decreasing water levels in lakes throughout East Africa. The flooded regions of the Toshka Lakes west of Lake Nasser have decreased greatly over the years, exposing the former dune fields, and leaving a “bath-tub ring” of wetlands (dark region) surrounding the lake shorelines.

Heavy rains in the source regions of the Nile in the 1990s resulted in record water levels in Lake Nasser. In 1997, Lake Nasser began flooding westward down a spillway into the Toshka depression in southern Egypt, creating four new lakes over the next few years.

Har Nuur (“Black Lake”) is located in western Mongolia’s Valley of Lakes, part of a system of closed basins stretching across central Asia. These basins are the remnants of larger paleolakes (paleo- means “ancient”) that began to shrink approximately five thousand years ago as regional climate became drier. This oblique (looking at an angle) astronaut photograph captures the dynamic nature of the landscape of Har Nuur. The lake is encircled by sand dune fields that encroach on the lower slopes of the Tobhata Mountains to the west and south. Gaps in the mountains have been exploited by sand dunes moving eastward, indicating westerly winds. The most striking example is a series of dunes entering Har Nuur along its southwestern shoreline.
