In the good old colonial days" Mozambique caju nuts stocked the grocery stores of the world.  The cajus that you buy now in the grocery stores of the world come from India and cost less than the factory price in Pemba.  Well intended, but misguided, attempts by the Frelimo Government to centralise the marketing of cajus collapsed, leaving the peasant farmers without access to the markets.  More recently "carpetbagger" foreigners are travelling the countryside buying up what remains of production at giveaway prices and selling it on at huge profits to themselves.  The same has happened with other crops such as sorghum, rice, and corn.  The colonial hegemony has been replaced by an equally foreign band of opportunists.  The Portuguese may be gone but the antiquated Portuguese ways of administration have survived, dominated by a new Portuguese-educated elite who know no other way.
