Authors:Asit K. Biswas
Abstract:With high and accelerating population growth and with low and declining efficiency in the use of resources, Africa is currently facing a long-term declining trend. Since agriculture accounted for 41% of the GDP of Africa in 1982, formulation and implementation of efficient land use policies are prerequisites if the long-term adverse trend is to be reversed.
