To engage all stakeholders in the irrigation and agriculture system in Egypt, several water user associations were developed, and the farmers were trained. Demonstration irrigation canals owning to WUAs is being used to apply the activities of on-farm water management to demonstrate the benefits of good agriculture practices (GAP) to them.
