| Pongkijvorason and Roumasset addressed a relevant topic for managing irrigation water in large irrigation schemes. Since seminal work by Carruthers and Clark (1983), we know that managing large irrigation schemes in Asian alluvial plains is a daunting problem and that the current regimes have performed much worse than initially planned. This judgment is shared by Rijsberman, who also highlights the unsustainable patterns of groundwater use in many develeping countries. Perhaps this is the context which best fits the analysis that Pongkijvorason and Roumasset developed in their paper, although they perhaps rightly refrain from mentioning a real one. The problem Pongkijvorason and Roumasset address is characterised by a non-trivial and complex dynamic and spatial problem, which attempts to obtain the optimal pricing paths for surface water rates and water use regimes (surface and groundwater). There are three sources of complexity, namely, canal conveyance losses, canal return flows and groundwater percolation from leakage and seepage. The Pongkijvorason and Roumasset model is set out to characterise optimal water surface pricing under no institutional constraint regarding three crucial features | |
