Moussa Kamara, 47, a baker and a Tolou Keur garden caretaker, shows a sketch of a Tolou Keur garden, which holds 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, as he speaks to journalists whilst sitting with his family members in a courtyard at his house in Boki Diawe, within the Great Green Wall area, in Matam region, Senegal, July 12, 2021. Kamara is part of a project that aims to create hundreds of such gardens - known as 'Tolou Keur' in Senegal's Wolof language - that organisers hope will boost food security, reduce regional desertification and engage thousands of community workers. "This project is incredibly important," said Kamara. "When you grow one tree, over 20 years people and animals will benefit from it."REUTERS/Zohra Bensemra SEARCH "BENSEMRA REFORESTATION" FOR THIS STORY. SEARCH "WIDER IMAGE" FOR ALL STORIES
