Geography of Western Sahara

Western Sahara is a territory in Northern Africa, bordered by the North Atlantic Ocean, Morocco proper, Algeria (Tindouf region), and Mauritania. Geographic coordinates: 24°30′N 13°00′W / 24.500°N 13.000°W / 24.500; -13.000

Topography of Western Sahara
Desert Coast of Morocco and Western Sahara, 2014. North is to upper right corner of photo. Note the straight lines produced by strong northerly winds that blow parallel to the coast, producing wind streaks of sand and sand-free surfaces. Also note the transport corridor of roads, railroads and conveyor belt system (vertical line at left) that transport phosphates 100 kilometres (62 mi) from inland mines to the coast. Strong northerly winds blow dust and phosphate into the desert, giving a jagged edge to this line on its south side.[1]

Size of Western Sahara

edit

The size of Western Sahara, a region located in North Africa, is a critical aspect of its geopolitical and environmental profile. The territory’s vastness impacts its resource distribution, strategic importance, and the ongoing conflict over its sovereignty. Western Sahara is a significant area of study for its complex history and its role in regional and global geopolitics.

Area

edit

Western Sahara encompasses approximately 266,000 square kilometers (102,703 square miles), which places it among the larger regions of Africa. This measurement provides a broad perspective on the land’s scale, revealing its comparative size to other nations and regions. For instance, Western Sahara is slightly larger than the United Kingdom but smaller than some of Africa’s largest countries, such as Algeria and Sudan.[2] The size of Western Sahara is not merely a numerical fact; it is intrinsically linked to its physical geography and the strategic interests it holds for various stakeholders. The arid climate and extensive desert areas define much of its landscape, influencing the lifestyle of its inhabitants and the approaches taken by both local and international actors in addressing the territory's status and development.[3]

The region’s area also affects logistical considerations, such as the management of natural resources and the implementation of infrastructure projects. Its size presents both challenges and opportunities for resource exploration, environmental management, and territorial administration. Despite its vastness, much of Western Sahara remains sparsely populated, with the majority of its residents living in a few concentrated areas. This uneven distribution of population relative to the land area plays a significant role in the political and humanitarian issues faced by the region.

Geographic Context

edit

Western Sahara's geographic location is pivotal in understanding its significance. Situated in the northwest corner of Africa, it is bordered by Morocco to the north and east, Algeria to the northeast, Mauritania to the southeast, and the Atlantic Ocean to the west.[4] This strategic position places it at the intersection of several historical and cultural exchange routes, which have influenced its development and the broader regional dynamics.

The landscape of Western Sahara is dominated by desert terrain, with features such as sand dunes, rocky plateaus, and sparse vegetation. The coastal areas along the Atlantic Ocean provide a contrast to the inland desert, offering a more temperate climate and supporting limited but important marine and coastal ecosystems.[5] The terrain’s aridity and the lack of significant water resources have shaped the settlement patterns and economic activities within the region. Historical trade routes and migratory paths that traverse Western Sahara are a testament to its historical significance in connecting different parts of Africa and beyond.

Additionally, the desert environment poses unique challenges for infrastructure development and resource management. The region's natural resources, including phosphate deposits and potential offshore oil reserves, add another layer of complexity to the geopolitical stakes associated with its size and geography.[6]

Land

edit

Terrain

edit

The terrain is mostly low, flat desert with large areas of rocky or sandy surfaces rising to small mountains in south and northeast.

Elevation extremes:

Lowest point: Sebjet Tah, −55 metres (−180 ft), a depression in the northwest part of Western Sahara straddling the Morocco border
Highest point: Unnamed elevation, 701 metres (2,300 ft), east of Awsard (Aousserd)[7]

Natural resources

edit

Phosphates, iron ore, and fishing resources on Atlantic Ocean coast

Land use

edit

Arable land: 0.02%

  • Permanent crops: 0%
  • Other: 99.98% (2005)

Irrigated land: N/A

Natural hazards

edit

Hot, dry, dust/sand-laden sirocco wind can occur during winter and spring; widespread harmattan haze exists 60% of time, often severely restricting visibility. Flash flooding occurs during spring months.

Environment

edit

Climate

edit

Western Sahara has a hot desert climate (Köppen climate classification BWh). Annual average rainfall is below 50 millimetres (2.0 in) everywhere. Along the Atlantic coast, average temperatures, both high and low, are constant and very moderated throughout the year because cool offshore ocean currents considerably cool off the climate, especially during the day. However, summertime is long and extremely hot and wintertime is short and very warm to truly hot further in the interior, where cooling marine influences aren't felt anymore. Average high temperatures exceed 40 °C (104 °F) in summer during a prolonged period of time but can reach as high as 50 °C (122 °F) or even more in places such as Smara, Tichla, Bir Gandus, Bir Anzarane, Aghouinite, Aousserd and others. Average high temperatures exceed 20 °C (68 °F) in winter but average low temperatures can drop to 7 °C (45 °F) in some places. The sky is usually clear and bright throughout the year and sunny weather is the norm.
