The Western Sahara region remains a highly contentious region and most unexplored, writes Dr Nicolaas C Steenkamp.

The vast expanse of the Western Sahara – on the Atlantic Ocean and dominated by the Sahara Desert – holds a unique position in North Africa. This region possesses a complex geological history, diverse geography and a contentious political climate. Beneath its arid surface lies a wealth of mineral resources, sparking speculation about the potential development of a mining sector. However, this potential is intricately intertwined with ongoing political conflict, raising crucial questions about feasibility and ethical considerations.
Geological setting
Western Sahara’s geological setting is dominated by the Precambrian cratonic rocks of the Reguibat Shield, an extensive area of ancient and stable continental crust. These ancient rocks are known to host a variety of valuable minerals, including phosphates, iron ore, manganese, and potentially elements like lithium and cobalt.
Phosphate deposits are perhaps the most well-known mineral resource in Western Sahara. These deposits are believed to have formed in shallow marine environments. They represent a significant portion of the world’s known phosphate reserves, making Western Sahara a player of potential importance in the global fertilizer market.
Iron ore deposits are also present in Western Sahara, particularly in the banded iron formations of the Precambrian rocks. These deposits hold promise for the development of an iron ore mining industry, potentially contributing to the region’s economic development.
There are indications of other likely valuable minerals. Limited historic exploration activities suggest the presence of manganese, copper and even hints of lithium and cobalt. While these deposits are less well-defined, they add another layer of complexity to the region’s mineral wealth.
Landscape of contrasts
The Western Sahara landscape consists of contrasting features. The majority of the region is dominated by the Sahara Desert, characterised by high day temperatures, scarce rainfall and wind-sculpted sand dunes known as ergs. The eastern portion of the territory transitions into a rocky plateau, the Hammada de Tindouf, while the western coastal areas are marked by low-lying plains and lagoons.
This varied terrain presents both opportunities and challenges for potential mining operations. The flat, arid plains might offer easier access for establishing mines and transporting materials. However, the harsh climate poses logistical difficulties, requiring significant investment in infrastructure and technology to ensure the viability of mining projects.
The Western Sahara experiences an extreme desert climate. Temperatures soar to scorching highs, often exceeding 45°C in the summer, while nights are cold, dropping below freezing in the winter months. Rainfall is scarce and erratic, averaging less than 100mm annually. This aridity presents a significant challenge for any exploration or mining endeavour. Water scarcity not only affects the viability of mining operations but also limits the potential for supporting settlements and infrastructure development.
Political landscape
The political situation in Western Sahara is a contentious one. Morocco claims sovereignty over the territory, while the Polisario Front, a Sahrawi independence movement, seeks to establish an independent Sahrawi Arab Democratic Republic (SADR). The United Nations does not recognise Morocco’s claim and considers Western Sahara a non-self-governing territory. This unresolved conflict creates significant uncertainty regarding the development of any natural resources in the region.
The potential development of a mining sector in Western Sahara highlights a number of ethical concerns. The ongoing political conflict raises questions about resource ownership and benefit- sharing, ensuring that any mining activity respects the rights and interests of both the Sahrawi people and the Moroccan interests in the region. Additionally, environmental considerations of mining operations in arid environments might have detrimental impacts on an already fragile ecosystem. Sustainable practices and strict environmental regulations will be essential to minimise the impact on the delicate desert landscape.
On the other hand, the development of a mining sector in Western Sahara holds the potential for significant economic benefits. Mining could create jobs, generate revenue for infrastructure development, and contribute to the region’s overall economic growth. However, these benefits are not without their challenges.
Path forward
The future of developing and establishing a mining sector in Western Sahara is uncertain. Moving forward will require a multifaceted approach that considers several key aspects.
Resolution of the political conflict remains at the top of this list, where a peaceful resolution to the political conflict is crucial. This could involve international mediation and agreements that respect the rights of all parties involved.
Sustainable practices and environmental regulations must be paramount. Strict regulations and responsible mining practices are essential to minimise the impact on the fragile desert ecosystem. Water management, waste disposal and land reclamation strategies will be critical for sustainable mining operations. The harsh environment and remote location of many potential mining sites necessitate significant infrastructure development. Investment in transportation networks, power generation and water desalination plants will be crucial for establishing a viable mining sector. Transparency and accountability are essential throughout the development process. Clear regulations, monitoring mechanisms, and independent oversight will help ensure that mining activities are conducted ethically and responsibly. This will also help build trust among stakeholders and foster international cooperation.
The Western Sahara holds a wealth of mineral resources with the potential to contribute to the region’s economic development. However, unlocking this potential requires careful consideration of complex geological, geographic, political and ethical aspects. A collaborative approach that involves all stakeholders, prioritises environmental sustainability, and respects the rights of the Sahrawi people is essential. Only then can the future of mining in Western Sahara be truly viable and beneficial for all involved.
