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

This study estimates and compares the effects of small and large irrigation dams on cropland productivity in South Africa. To this end, a panel data set of South African river basins is constructed. The econometric analysis reveals that although la...
