Climate Change and Rainfall in the Chott el Djerid Basin, Tunisia

33.8N 8.4E

June 5th, 2013 Category: Climate Change, Wetlands VIIRSSuomi-NPP

Tunisia – June 4th, 2013

The Chott el Djerid is an ephemeral salt playa situated in an arid zone closed basin which has a catchment area of 10500km2. The Chott el Djerid itself has a surface area of approximately 5360km2. The interpretation of climate change in this period and its relation to sediments, specifically lake shoreline deposits found within the Chott el Djerid basin, have become more controversial in recent times. Studies have shown that due to climate change, rainfall in the basin has been decreasing in recent years. The recorded presence of surface water on the Chott el Djerid can be related to rainfall events in the basin (click here for more information).

Algeria and Tunisia - April 14th, 2012

The Mediterranean coast from Morocco (left), across Algeria, to Tunisia (right) is green and vegetated, in contrast with the sands of the Sahara Desert to the south. Two large lakes can be observed amidst the desert sands, however: Chott el Djerid and Chott Ech Chergui.

The former is located in Tunisia. It is a large endorheic salt lake with a width of 20 km (12 mi) at its narrowest point, and a length of over 250 km (160 mi). Here, it appears various shades of tan, with the lighter areas likely indicating a salt crust.

Chott Ech Chergui is a large endorheic salt lake in northwestern Algeria, located at in the Saharan Atlas. The lake has an area of about 2000 km² and is one of the largest lakes in Algeria. Chott Ech Chergui is designated a Ramsar wetland of international importance.

Libya and Tunisia - April 14th, 2012

Bright blue and green sediments and phytoplankton can be observed in the Gulf of Gabes and all along the shores of Tunisia, stretching to the Libyan coastline as well. The color is darker green in the Gulf of Gabes and around the Kerkennah Islands, and bright blue east of Djerba.

Further inland, the Chott el Djerid appears as a large, dark tan area. It is a large endorheic salt lake in southern Tunisia and the largest salt pan of the Sahara, with a surface area of over 7,000 km2. South of Chott el Djerid, the Grand Erg Oriental desert begins.

Tunisia and Algeria - November 23rd, 2011

Greenish sediments can be seen in the Gulf of Gabes off the coast of Tunisia between the Kerkennah Islands and Djerba. The former (north) is an archipelago with an area of 160 km2, while the latter (south) is the largest island of North Africa, with a surface area of 514 km².

Visible to the west of the gulf, further inland, is a large tan area, known as the Chott el Djerid. It is a large, endorheic salt lake in southern Tunisia and the largest salt pan of the Sahara Desert. The golden area of desert south of the Chott el Djerid is the Grand Erg Oriental, a sand dune sea stretching across Algeria to Tunisia.

Tunisia and Algeria - October 13th, 2011

Greenish sediments can be seen in the Gulf of Gabes off the coast of Tunisia between the Kerkennah Islands, an archipelago with an area of 160 km2, and Djerba (south of the former), the largest island of North Africa at 514 km².

The large tan area inland, west of Djerba, is the Chott el Djerid, a large endorheic salt lake in southern Tunisia. It is the largest salt pan of the Sahara Desert. Moving southward, one comes to the golden yellow expanse of the Grand Erg Oriental, a sand dune sea stretching across Algeria to Tunisia.
