In two of his recent publications, Professor G F Townsend draws our attention to the very propitious plant Prosopis as an excellent candidate for multipurpose usage in arid zones, especially in the tropics. The pods and seeds of Prosopis plants are known to be rich in proteins and can be used, therefore, as an excellent source of edible and nutritious flour for man. The plant also produces a great amount of nectar and pollen which yields well-flavoured and high quality honey. Prosopis can serve as an important fodder source for livestock, a fuel, a stabilizer of shifting desert sands and as a provider of humus and nitrogen in the soil. Many species of Prosopis can grow successfully under very adverse conditions such as scarcity of rain and very poor soils.
