Senegalese agricultural engineer Aly Ndiaye, who is the head of the training and green sectors division at the eco-villages department of the Senegalese Agency for Reforestation and the Great Green Wall, waters trees at a newly built Tolou Keur garden, in Boki Diawe, within the Great Green Wall area, Matam region, Senegal, July 10, 2021. Gardens known as 'Tolou Keur' hold plants and trees resistant to hot, dry climates, and are planted with circular beds that allow roots to grow inwards, trapping liquids and bacteria and improving water retention and composting. Ndiaye stressed the importance of "smaller actions that are permanent". "A thousand Tolou Keur is already 1.5 million trees," said Ndiaye. "So if we start, we can make a lot."
