This booklet is developed for field staff involved in the design, implementation, operation and maintenance of water management projects for agricultural production; technicians and agents in local irrigation and extension services, NGOs and local government employees who work at field level, carry out the assessment of the local situation and have contact and negotiate with stakeholders using available water sources. For this reason the guide was given a pocket format, so professionals, practitioners and other field staff can easily carry it with them to the field.
