"According to the World Agroforestry Center, Garrity states, "Growing the right tree in the right place on farms in sub-Saharan Africa—and worldwide— has the potential to slow climate change, feed more people, and protect the environment. This tree, as a source of free, organic nitrogen, is an example of that. There are many other examples of solutions to African farming that exist here already."




This was encouraging.

    • Valuable Fuel

      The wood of many acacia trees is renowned for its excellent fuel properties and can also produce good charcoal. Since many African people still rely on wood as fuel for cooking and heating it is essential that acacia woodlands are managed effectively in order that the trees do not disappear altogether. In areas that have been overgrazed, bush-encroachment by acacia and the related Dichrostachys (as well as other species) is commonplace and restorative land management can harvest this resource as attempts are made to restore savannah conditions (i.e. trees and grass). Acacia sap or gum is another important product and the Sweet Thorn and Scented Thorn produce copious amounts which can be used as a glue. "Gum Arabic" was originally derived from the Three-hook Thorn and synthetic alternatives are now used as a binding compound in cosmetics, medicines, fast foods and paints. us why this is interesting
