The Screening of Multipurpose Tree Species for Agroforestry Practices in the Semiarid Ecozone of Ghana

  • Joseph Cobbina


The semiarid ecozone of Ghana forms part of the extensive West African savanna which covers an area of 3.5 x 106 km2 and stretches for about 4,000 km from the Guinea-Senegal cost in the west to Chad and Central Africa Republic in the east (Jones and Wild, 1975). In general, the amount of rainfall received decreases as one moves from south to north and also trees become smaller and more widely separated from one another.
