The Great Green Wall project aims to plant a line of trees nearly 8,000 kilometres long and 15 kilometres wide. This green belt would pass through 11 countries in the Sahel, from Senegal to Djibouti. It hopes to stop the desert from expanding and swallowing farmland. Many are happy with what is being achieved, but others are not, reports Farm Radio Weekly. Aliou Sow is a farmer in Senegal. He complains bitterly that the authorities planted trees in his community without consultation. While farmers travel miles on foot or by donkey to fetch water for the villages of Tessekeré, Amaly and Widou, wells are being dug specifically to irrigate nurseries for the Wall.
