Proper management of trees and forests is necessary to make resources sustainable. Trees or rather: woody plants in general play an important part in traditional farming systems in the tropics, not just as food and cash crops but also as suppliers of fuelwood and fodder. Farmers are also aware of the environmental benefits and use trees as fallow vegetation, hedges, windbreaks, erosion barriers, etc. Where these traditional roles of trees are diminishing due to increasing population pressure and/or changing land use, it is necessary to encourage and support local initiatives to plant trees.
