Role of ley farming in crop rotations in the tropics por Mohamed-Saleem, M.A., Fisher, Myles J.

“…Neverthless, evidence of voluntary and government-credit-backed adaptation of ley farming concepts to producer circumstances is not difficult to find in such West African countries as Nigeria and Mali. This should not, however, be construed as an indication of future trends in ley farming, since agricultural production in the region is subsistence oriented and farmers are content with the present livestock herding practices and see no urgency to introduce soil restoration alternatives, as there are no visible manifestations of rapid environmental degradation. …”
