Amadou Bathili, 50, a trainer who teaches how to build Tolou Keur gardens through the Tolou Keur programme, prepares a chicken cage at a newly built Tolou Keur garden in Boki Diawe department of Podor region, in an area which is part of the Great Green Wall of the Sahara and the Sahel area, in 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.
