If you want productivity and efficiency, put irrigation systems in the hands of farmers: Generally speaking big dam and irrigation systems in developing countries are less productive. When the control and management of such systems is not in the hand of farmers – the water users – it makes water reliability more vulnerable and less useful to farmers to intensify their cropping systems and adopt new technologies.
