Frequently Asked Questions

What countries make up the Sahel region?

The Sahel stretches across parts of Senegal, Mauritania, Mali, Burkina Faso, Niger, Nigeria, Chad, Sudan, and Eritrea. This semiarid belt runs approximately 5,400 km from the Atlantic Ocean in the west to the Red Sea in the east, forming the transition zone between the Sahara Desert to the north and the wetter savannas to the south.

What is the Great Green Wall initiative?

The Great Green Wall is an African Union initiative launched in 2007 to combat desertification by planting a mosaic of trees and vegetation across 8,000 km from Dakar, Senegal to Djibouti. The goal is to restore 100 million hectares of degraded land by 2030. By 2024, approximately 18 million hectares had been restored.

Why has Lake Chad shrunk so dramatically?

Lake Chad has shrunk by approximately 90% from 25,000 km\u00b2 in the 1960s to under 2,500 km\u00b2 today due to a combination of reduced rainfall from prolonged Sahel droughts, increased water extraction for irrigation by surrounding populations, and rising temperatures accelerating evaporation. Over 30 million people in four countries depend on the lake for water, fishing, and agriculture.
