Is Small Better? : A Comparison of the Effect of Large and Small Dams on Cropland Productivity in South Africa

We estimate and compare the effects of small and large irrigation dams on cropland productivity in South Africa. To this end, we construct a panel data set of South African river basins. The econometric analysis reveals that although large dams increase cropland productivity downstream, they have a...
