Rapid appraisal for improving existing canal irrigation systems

Low levels of performance on canal irrigation systems in developing countries are a major concern of many governments and aid agencies. A wide range of actions is possible to improve performance. The choice, mix and sequence of actions are often determined by professional preferences or national programmes but to fit well should be tailored for each individual irrigation system. Rapid rural appraisal techniques offer a cost‐effective approach, either through teamwork or through irrigation managers doing it themselves. In order to improve rapid appraisals, practitioners are encouraged to write about and share their techniques and experiences.
