Drain for gain : making water management worth its salt : subsurface drainage practices in irrigated agriculture in semi-arid and arid regions; Proefschrift Wageningen, UNESCO-IHE Institute for Water Education, Delft.

In this dissertation, the role of subsurface drainage to reduce waterlogging and salinity problems in irrigated agriculture in arid and semi-arid regions has been analysed and recommendations on how to improve subsurface drainage practices have been formulated. The study contains a synthesis based on eight case studies covering subsurface drainage practices in Egypt, India and Pakistan. Professionals can use these recommendations to improve planning, design, implementation, and O&M practices. The recommendations can also help to address issues related to an enabling environment (who will pay the costs of drainage?) and the changing roles of institutions to improve farmers' participation and organization
