This monograph provides a framework for use in the assessment of irrigation system performance and diagnosis of the primary causes of different levels of performance actually achieved. The framework is tested using 15 case studies of irrigation performance in a range of countries in Asia, Africa and South America with a number of different design and management environments. Using this framework it is possible to identify where there are shortcomings to existing approaches to objectve setting, implementation, monitoring and evaluation, and to guide irrigation managers towards remedying these deficiencies. The focus is on hydraulic performance in the main canal system, but it also includes agricultural performance and issues of environmental sustainability in its scope. One conclusion from the study is that systems with simple management objectives and simple physical design generally perform considerably better than more complex systems, even though complex systems have higher potential for good performance.
