Agricultural growth in Africa has accelerated, yet most of this growth has been driven by land expansion. Land expansion potential is reaching its limits, urging governments to shift towards a green revolution type of productivity-led growth. Given the huge public investments required, this paper aims to assess the potential impacts of a green revolution. Results from a CGE model for Ghana show that green revolution type growth is strongly pro-poor and provides substantial transfers to the rest of the economy, thus providing a powerful argument to raise public expenditure on agriculture to make a green revolution happen in Africa. © 2009 John Wiley & Sons, Ltd.
