Southern Provinces

The Southern Provinces ( "Al-Aqalim al-Janubiyah") or Moroccan Sahara are the terms used by the Moroccan government for Western Sahara. These two official Moroccan denominations explicitly include all of Western Sahara, which spans three of the country's 12 top-level administrative regions (although only one region lies entirely within Western Sahara). A frequent use of the term "Southern Provinces" is found for example in Moroccan state television (weather forecasts, displayed maps on the news, government statements, etc.).
Overview.
The Moroccan government controls and administers roughly four-fifths of Western Sahara (the part west of the Moroccan Wall), while the rest makes up the Free Zone held by the Sahrawi Arab Democratic Republic. Government and private companies exploit coastal areas for fishing and the land areas for phosphate mining.
The two thirds of Western Sahara that are controlled by Morocco are treated by the government as normal Moroccan territory. The government conducts various economic and social development programs and includes these "Southern Provinces" in the national budget of government funding, national sport competitions, education programs, and national parliamentary elections. Following the Green March and the Madrid Accords signed with Spain and Mauritania in 1975, Morocco took control of Saguia el-Hamra, and the northern part of Río de Oro, while Mauritania took control of the remaining part of Río de Oro, renamed as Tiris al-Gharbiyya.
A locally based Saharawi national liberation movement, the Polisario Front launched a guerrilla war, with the crucial financial and logistical backing of Algeria and Libya, aiming to win independence of the territory under the "Sahrawi Arab Democratic Republic" (SADR). Following bloody clashes with the Polisario troops (SPLA) and deteriorating ties with Algeria, Mauritania pulled out in 1979 and gave up its share in the Western Sahara in order to avoid further complicated conflicts with the Sahrawi Republic, Algeria, and Morocco. Morocco then seized the opportunity and took control of the remaining part of Río de Oro as well, which had been recognized by the Moroccan regime as Mauritanian a few years earlier.
Since a United Nations-sponsored ceasefire agreement in 1991, about two thirds of the territory is administered by Morocco, including the majority of the coast. This territory is separated by fortified berm from the Polisario Front-controlled remainder, which has a population of about 30,000. Polisario's army is considered incapable of covering the vast one-third of Western Sahara, east of the Moroccan berm. Moreover, most of Polisario's army is thought to be concentrated in the Tinduf area inside Algeria, protected by Algeria from the long arm of Morocco's artillery and air force.
The ceasefire line corresponds to the route of the Moroccan Wall (the military berm). Both sides claim the territory of Western Sahara in its entirety. The Sahrawi Arab Democratic Republic had been recognized by 84 nations, and is a full member of the African Union, but not of the UN. Moroccan territorial integrity is implicitly recognized by the Arab League with strong reservations from Algeria and Syria.
Administratively, Morocco divided the territory under its control into administrative units ("wilayas"). Flags and coats of arms were created for the three wilayas of Boujdour, Smara and Laayoune. There were further changes in the territories in 1983, with the area becoming four wilayas through the addition of Dakhla. In 1990 Wadi al-Dhahab (Río de Oro) was added.
Morocco has assigned a special satellite TV channel for the "Southern Provinces", called Laayoun TV.
Population.
Following the 1975 Green March, the Moroccan state has sponsored settlement schemes enticing thousands of Moroccans to move into the Moroccan-occupied part of Western Sahara (80% of the territory). By 2015, it was estimated that Moroccan settlers made up at least two thirds of the 500,000 inhabitants. In addition to guaranteeing a right of return for the Sahrawi refugees, the Sahrawi government in exile has indicated a willingness to offer Sahrawi citizenship to Moroccan settlers and their descendants in a future independent state.
