Africa: A new Green Revolutino in Africa?

For some time now, there's been talk of a new Green Revolution for Africa – because "Africa missed the first Green Revolution" or because "the first Green Revolution missed Africa". Now a new project, the Alliance for a Green Revolution in Africa (AGRA), is trying to put the concept into operation. This paper aims to describe what a Green Revolution really signifies, why such projects haven't worked before and why AGRA won't work either, in order to help people trying to take positions at the local, national and regional levels.
