This paper focuses on the evaluation of a participatory approach aimed at supporting groups of small-scale farmers in the design of joint drip irrigation projects. The authors' idea was to create a sustainable social learning environment in which they could acquire adaptive knowledge about new irrigation technology and about designing and managing a joint irrigation project while at the same time improving their negotiation capacities. They developed a framework to evaluate the process as well as the outputs and outcomes of the use of their approach with four groups of smallholder farmers in the Tadla irrigation scheme in Morocco. Their findings showed that the learning environment made it possible to compensate for the knowledge differential among stakeholders and to co-produce knowledge that can be mobilised by smallscale farmers to help them make better informed decisions when choosing whether or not to engage in a joint irrigation project and when developing and implementing such a project. They expect that this will ultimately contribute to supporting the shift from state water to community water through a shared understanding of the technical, economic and social issues, and options related to the management of irrigation water.
