Separation barrier dividing the disputed territory of Western Sahara

The Moroccan Western Sahara Wall or the Berm, also called the Moroccan sand wall (الجدار الرملي المغربي في الصحراء الغربية), is an approximately berm running south to north through Western Sahara and the southwestern portion of Morocco. It separates the Moroccan controlled areas (the Southern Provinces) on the west from the Polisario controlled areas (Free Zone, nominally Sahrawi Arab Democratic Republic) on the east. The main function of the barriers is to exclude guerrilla fighters of the Polisario Front, who have sought Western Saharan independence since before Spain ended its colonial occupation in 1975, from the Moroccan controlled western part of the territory. According to maps from the United Nations Mission for the Referendum in Western Sahara (MINURSO) or the United Nations High Commissioner for Refugees (UNHCR), in some places the wall extends several kilometers into internationally recognized Mauritanian territory.

The wall is also called the Western Sahara berm and the Western Sahara separation barrier.

The fortifications were progressively built by Moroccan forces starting in 1980, with help from South African, South Korean, and Israeli advisors, and formally ending on 16 April 1987.

In the summer of 2005, the Moroccan Army accelerated the expulsion (begun in late 2004) of illegal immigrants detained in northern Morocco to the eastern side of the wall, into the Free Zone. The Polisario Front and the MINURSO rescued several dozen lost in the desert, who had run out of water. Others died of thirst. By October, the Polisario had received 22 immigrants in Mehaires, 46 in Tifariti and 97 in Bir Lehlu. They were from African countries (Gambia, Cameroon, Nigeria, Ghana, etc. ), except a group of 48 who were from Bangladesh.

Since 2008, a demonstration called "The Thousand Column" is held annually in the desert against the barrier by international human rights activists and Sahrawi refugees. In the 2008 demonstration, more than 2,000 people (most of them Sahrawis and Spaniards, but also Algerians, Italians, and others) made a human chain demanding the demolition of the wall, the celebration of the self determination referendum accorded by the UN and the parts in 1991, and the end of the Moroccan occupation of the territory. During the 2009 demonstration, a teenage Sahrawi refugee named Ibrahim Hussein Leibeit lost half of his right leg in a landmine explosion. The incident happened when Leibeit and dozens of young Sahrawis crossed the line into a minefield while aiming to throw stones to the other side of the wall.

Effectively, after the completion of the wall, Morocco has controlled the bulk of Western Sahara territory that lies to the north and west of it, calling these the kingdom's "Southern Provinces". The Polisario founded Sahrawi Arab Democratic Republic controls the mostly uninhabited "Free Zone", which comprises all areas to the east of the barrier. Units from the United Nations mission MINURSO separate the two sides, and enforce cease fire regulations.

Western attention to the wall, and to the Moroccan annexation of Western Sahara in general, has been minimal, apart from Spain. In Africa, the annexation of Western Sahara by Morocco has attracted somewhat more attention. Algeria supports the Polisario Front "in its long running desert war to oppose Moroccan control of the disputed area". The Organization of African Unity/African Union (AU) and United Nations have proposed negotiated solutions. The AU's stance on Western Sahara led to Morocco's exit from the organization. After a 33 year absence, Morocco rejoined on 30 January 2017, despite 9 member states voting against, but 39 supporting. Morocco was re admitted with the understanding that Western Sahara will remain an AU member. The membership of relatively wealthy Morocco was welcomed by many members, as the AU has been criticized for being overly dependent on non African donor funding.
