Understanding the Region
The Sahel
Geography
A Belt Across
a Continent
The Sahel — from the Arabic word meaning "shore" — is a 5,400-kilometer semi-arid band stretching from the Atlantic Ocean to the Red Sea, home to more than 150 million people.
Covering roughly 3 million square kilometers (1.1 million square miles), it spans Senegal, Gambia, Mauritania, Guinea, Mali, Burkina Faso, Niger, Chad, Cameroon, and Nigeria. — dozens of ethnic groups, languages, and religious traditions living side by side.
The region receives between 200—800mm (8 to 32 inches) of rain annually. Droughts, desertification, and unpredictable rainfall are intensifying year by year, deepening humanitarian pressures across the belt.
The Crisis in Depth
What Drives
Instability
Displacement & Conflict
Armed groups exploiting governance gaps have displaced over 4 million people. Communities that once coexisted across ethnic and religious lines are increasingly fragmented by violence and resource competition.
Education Crisis
More than 6,000 schools have closed in Burkina Faso alone. Across the region, an entire generation risks growing up without education — the most powerful antidote to radicalization and poverty.
Climate Vulnerability
The Sahel is warming 1.5x faster than the global average. Desertification, erratic rainfall, and competition for shrinking arable land are deepening food insecurity and fueling farmer-herder conflicts.
Country Profiles
Ten Nations,
One Crisis
Burkina Faso
Population 24.6M, 65% Under 30. Over 2M Internally Displaced. Subsistence Agriculture And A Growing Mining Sector. Home To Sahel Peace University.
Mali
Population 25.9M. Home To Timbuktu, Ancient Trading Hub. Reliant On Agriculture, Livestock, And Gold Extraction.
Niger
Population 28.8M. Diverse cultures and vast Saharan landscapes. One of the world's fastest-growing demographics.
Chad
Population 21M. Heavily reliant on agriculture (livestock, cotton) and oil exports. Median Age is 15.7 years, making it one of the youngest populations globally.
Senegal
Population 19.4M. Rich cultural heritage, music, and strategic location. Service-based economy with strong fishing and agricultural sectors.
Mauritania
Population 5.5M. Majority live in the temperate, urbanized south, heavily concentrated in the capital city, Nouakchott. Relies heavily on mining (iron ore), fishing, and livestock
Gambia
Population 2.9M. Heavily Centered Around Agriculture (Especially Peanut Production) And Tourism.
Guinea
Population 15.4M. Highly youthful population, with a median age of just 18.5 years. Relies heavily on mining operations (bauxite, iron ore) and agriculture.
Cameroon
Population 30M. Strong base of natural resources and agriculture. Diverse terrain from savannas to rainforests.
Nigeria
Population 242M. Exceptionally young population with a median age under 19. Economy driven by its vast petroleum and natural gas resources.
The Environment
Land, Climate
& Survival
The Sahel's environmental crisis is inseparable from its humanitarian crisis. As the land degrades, livelihoods collapse — and conflict ignites.
The Great Green Wall — an African Union initiative to restore 100 million acres by 2030 — offers a model for what integrated environmental and social investment can achieve.
The idea of the Great Green Wall is to create an 8,000-kilometer wall of green and productive landscapes stretching from Senegal in the West to Djibouti in the East.
