The Sahara Desert, one of the largest and most iconic deserts in the world, covers a significant portion of northern Africa. However, no single country is 90% covered by the Sahara. The desert spans multiple countries, each with varying degrees of desert coverage. Understanding the geographical distribution of the Sahara helps in appreciating its vastness and the countries it affects.
Which Countries Are Covered by the Sahara Desert?
The Sahara Desert stretches across 11 countries in northern Africa. These countries include:
- Algeria
- Chad
- Egypt
- Libya
- Mali
- Mauritania

- Niger
- Sudan
- Tunisia
- Western Sahara
Each of these countries has a portion of its territory covered by the Sahara, but none is entirely dominated by it.
How Much of Each Country Is Covered by the Sahara?
Here’s a closer look at how much of each country is covered by the Sahara Desert:
| Country | Percentage Covered by Sahara |
|---|---|
| Algeria | ~80% |

Egypt and Libya are among the countries with the highest percentage of their land covered by the Sahara, each with approximately 90%. However, it’s important to note that this doesn’t mean these countries are 90% desert, as they have other geographical features.
What Makes the Sahara Desert Unique?
The Sahara is not just a vast expanse of sand dunes; it is a complex ecosystem with diverse landscapes, including:
- Sand dunes (ergs)
- Rocky plateaus (hamadas)
- Gravel plains (regs)
- Dry valleys (wadis)
- Salt flats (shatts)
The Sahara’s climate is characterized by extreme temperatures, with scorching days and cold nights, and very little rainfall. This harsh environment has shaped unique adaptations in both flora and fauna.
How Does the Sahara Impact the Countries It Covers?
The Sahara Desert significantly influences the climate, economy, and culture of the countries it spans:
- Climate: The desert’s arid conditions contribute to extreme weather patterns, impacting agriculture and water resources.
- Economy: Many countries in the region rely on natural resources found in the desert, such as oil, gas, and minerals.
- Culture: The Sahara is home to diverse ethnic groups, each with rich cultural traditions and histories tied to the desert.
What Are the Challenges of Living in the Sahara?
Living in the Sahara presents several challenges:
- Water Scarcity: Access to water is limited, making agriculture and daily life difficult.
- Extreme Temperatures: The desert’s harsh climate can be challenging for both humans and wildlife.
- Isolation: Remote locations and vast distances between settlements can limit access to services and infrastructure.
Despite these challenges, the Sahara remains a place of fascination and resilience, with communities that have adapted to its demanding conditions.
