Algeria and Spain - December 22nd, 2011

A strip of land along the coast of Algeria appear green and fertile, in contrast with the Sahara Desert to the south. Visible parallel to the coast are the Saharan Atlas Mountains. Near the center of the shoreline, just below the change in terrain, is the Chott Ech Chergui, a large endorheic salt lake (appearing tan in color, here).

To the north, the eastern part of the Iberian Peninsula can be observed in the upper left quadrant, with the Spanish Balearic Islands, including Majorca (the largest), Minorca (to its east) and Ibiza and Formentera (to its west), visible in the Mediterranean Sea at the upper center and right.

Algeria - December 22nd, 2011

This shows Algeria, the largest country in Africa, the Arab world, and the Mediterranean. Most of the coastal area is hilly, sometimes even mountainous, and there are a few natural harbours. The area from the coast to the Tell Atlas is fertile. South of the Tell Atlas is a steppe landscape, which ends with the Saharan Atlas; further south, there is the Sahara desert.

The Tell Atlas merge with the Saharan Atlas in eastern Algeria. Between the two ranges lie vast plains and highlands. The vast mountain ranges of Aures and Nememcha, occupy northeastern Algeria and are delineated by the Tunisian border. The Ahaggar Mountains, also known as the Hoggar, are a highland region in central Sahara, southern Algeria.

Algeria - December 11th, 2011

Algeria is the largest country in Africa, the Arab world, and the Mediterranean. Its southern part includes a significant part of the Sahara. To the north, the Tell Atlas mountains run parallel to the Saharan Atlas, further south, with vast plains and highlands between them. Both Atlas tend to merge in eastern Algeria. The Atlas Mountains preserve the north from desertification.

Visible near the center left is the Chott Ech Chergui, is a large endorheic salt lake in northwestern Algeria, located in the Saharan Atlas. The lake has an area of about 2000 km² and is one of the largest lakes in Algeria. It is also designated a Ramsar wetland of international importance; the Ramsar site has an area of 8555 km².

Northwestern Algeria - February 24th, 2009

A small section of Algeria’s Mediterranean coastline, near the border with Morocco, is visible in the upper left corner. Slightly inland, a large green lake whose shores are coated with tan sediments, is visible.

Called the Sebkha of Oran, it is a salt lake that covers most of the territory of the Boutlélis District in Algeria’s Oran Province.

Moving farther inland, away from the fertile green coast, another large lake can be observed. This lake, known as Chott Ech Chergui, is a large endorheic salt lake in the Saharan Atlas. It is one of the largest lakes in Algeria, with an area of about 2000 km². This area is designated a Ramsar wetland of international importance.

According to the Ramsar Organisation, it is the second largest chott in North Africa; an extensive closed depression containing permanent and seasonal saline, brackish, and freshwater lakes and pools, as well as hot springs.

The habitats here are diverse, including steppe areas that are always green, the land around the chott and the “sebkhas” which has no vegetation, and acquatic areas with lake and marsh vegetation.

Many threatened and vulnerable plant species are present. The area is also important for several species of migratory waterbirds, which use it as a site for nesting and wintering.

The area is used for agriculture and raising livestock by humans. However, human use also may also cause environmental problems, such as overgrazing, poaching, desertification, and deforestation for firewood.
