The great biological diversity in Acacia and Prosopis is reflected in their wide distribution and ecological amplitude, and particularly in the tolerance of some species to extremes of drought and salinity. Their value, however, lies not only in their ability to thrive under adverse conditions, but also in the range of useful products that they provide. Among these, animal fodder, both pods and browse, is of central importance. The wood of both genera is an essential source of fuel in arid and semi-arid areas, and the timber is also valued for a wide range of purposes. The greatest economic value of Acacia, however, lies in the production of gums and tannins for industrial uses. The promotion of more lesser-known species in planting programmes would help to conserve the valuable diversity in both genera.
