Combating desertification in winter rainfall regions of North Africa and the Middle East

Abstract

Perennial pasture establishment poses particularly difficult problems when it is associated with common grazing tradition. Grazing management of perennial varieties requires light browsing on the shrubs at a rate roughly equivalent to their average annual growth. Annual pasture species offer a more realistic opportunity for revegetation and improvement of arid and semi-arid regions because their introduction would require less change to the current socio-economic environment.
