"Is Irrigation in Northern Ghana a Good Adaptation Strategy to Climate Change: A CGE-W Study"
by Gueneau, Arthur and Sherman Robinson

Despite the more than twenty years of rapid economic growth in Ghana, the historical North-South divide in standards of living has widened. In order to address poverty in Northern Ghana, in 2008 the Government launched the Savannah Accelerated Development Initiative (SADI). PArt of this initiative aims at increasing irrigation to protect against climate change.

In this paper, we use the CGE-W framework based on the IFPRI CGE model of Ghana and a water basin model of the White Volta to explore this proposition. We first look at how weather variability affects agricultural GDP and rural income in Northern Ghana, and, as a result, agricultural terms of trade in the whole country. Then we implement differently sized irrigation schemes, and discuss their potential benefits, and how water availability limits their efficiency. Finally we test the same large-scale irrigation project under four different climate change scenarios, and conclude on the conditions needed to make those worthwhile adaptation to climate change.
