The roots of the acacia tree fix nitrogen in the soil, making it more fertile and helping families to grow trees and crops more effectively. The seeds of the tree can be eaten once dried, and the leaves can be fed to livestock. The tree also produces a resin — gum arabic — which can be used in cooking and to make glue, providing families with an income once sold.
Trees are a vital part of life for families in rural Africa. They provide nutritious food to eat all year round, and products that can be sold at market to earn a vital income.
