6. Acacia Trees What are the benefits of this project?
"Forests and trees in arid zones are central to understanding the process of desertification - they provide local communities with sustainable livelihoods but also fodder livestock, fuelwood, medicine, timber, resin and gums.
The project was set up in Senegal ,2004 with the goal of helping people to plant and manage of acacia forests in an effort to halt desertification, while helping villages in at-risk areas.
As well as providing foliage for animals and fuel for cooking, the trees also produce arabic gum, which is a product that is used in the food and pharmaceuticals industries.
What problems might there be?

7. Magic Stones (Diguettes or demi lunes) Burkina Faso

Magic stones – circles of stones are placed on the ground to hold water on the soil rather than let it run quickly across the surface. This reduces soil erosion.‘
What is so good about this method?
