The role of Faidherbia albida tree species in parkland agroforestry and its management in Ethiopia

Abstract

Agroforestry has been defined as a dynamic ecologically based natural resources management system that through the integration of trees on farms and in the agricultural landscape, diversifies and sustains production for increased social, economic and environmental benefits for land users at all levels. This paper highlighted the role of Faidherbia albida tree species in Parkland Agroforestry and its management. Large part of the Ethiopian agricultural landscape is mostly dominant by Parkland Agroforestry practice. These practices are characterized by well grown scattered trees on cultivated land. F. albida is a multipurpose tree grown in addition to its gum production, used in soil fertility improvement as well as fuel and fodder production in rural communities. These trees have been promoted in agroforestry as its characteristic reverse phenology allows satisfactory production of crops under a full stand of the species. Several trials have shown the positive effect of F. albida on crops. In areas where there is too little crop rotation, severe cases of Striga infestation are more noticeable, often resulting in total crop failure. One of the cheapest means of improving his soil fertility, which could effectively reduce or eliminate Strigainfestation, is the use of the F. albida tree in an agroforestry practice on his farm. Socio- economically, F. albida have served as a fodder for livestock and the source of nectar for honey.
