Water Supply
Extra wells may need to be built in order to provide water
storage areas, helping to deal with the problem of irregular
rainfall.
Tree Planting
Trees anchor the soil, making it more stable for planting.
Leaves and other debris from trees decompose to contribute
organic matter to the soil. This serves as food for new vegetation.
In sufficient numbers, trees can also provide a barrier to
blowing sand, decreasing wind erosion. Tree barriers are also
a source of fuel, shade and food for nearby communities.
Eliminate free
grazing of animals
Trees and other vegetation can be protected from animals with
ôlive fencesö - fences made from prickly bushes. It may also
be possible to limit animal grazing to certain areas. In order
to decrease the damage done by grazing animals, some people
may have to give up their nomadic way of life, settling in
communities and growing vegetation specifically for animal
feed.
Many people keep animals as a way of earning a living. Providing
these people with another source of income might reduce reliance
on animal husbandry.
Protecting
Scarce Resources
It is possible to use trees and other resources in a sustainable
way. For example, branches can be cut from trees in such a
way that the tree is not damaged, and the branches grow back.
This is called pollarding. Like trees and other plants, soil
must be cared for as though it were a crop.
Education
Members of a community require education in order to use resources
wisely, adopt new farming methods and ensure the continued
fertility of the soil. Many successful projects can be repeated
in other areas, once the activities have been adapted to local
environmental conditions and culture.
