Table 1. The approach adopted in this study   Awareness raising phase Project simulation phase   Technical workshop Practical workshop Role-playing game Individual farm projects Co-design workshop Main questions What is drip irrigation about? How does it work? Why a joint project? What are the farming projects? What are the collective choices of the project?   Means Video projected presentation and group discussion Farmers visit other farmers who use drip irrigation Role-play scenario: design of a virtual joint project Survey made by the farmers themselves Simulation of farmers' project   Outputs Farmers formalize and share their problems and link them with drip irrigation Farmers build a consensus on the usefulness of the project Farmers understand that a joint project has to fit to individual needs Farmers define their farming project Farmers make collective choices for the terms of reference of a feasibility study   Outcomes Farmers gain knowledge on the drip irrigation technique Farmers gain knowledge on drip irrigation projects, create knowledge network Farmers gain knowledge on the pros and cons of joint projects Farmers commit themselves to the execution of the project and envisage the future Farmers take over the process
