"This book draws on over twenty years of experience gained in irrigation and drainage performance assessment. Performance assessment is an essential management task. If the use of water for irrigation is to be improved then we must understand current levels of performance and identify measures for improvement. This book provides guidelines to enable practitioners to apply the processes and procedures that have evolved. Developed by a working group of the International Commission on Irrigation and Drainage (ICID) it provides a generic framework for performance assessment with guidance on the theory and practice of how to audit and assess the performance of irrigation and drainage schemes. It will be of significant interest to those working within the areas of irrigation, drainage, soils and agricultural engineering."--BOOK JACKET. Performance assessment of irrigation and drainage is the systematic observation, documentation and interpretation of the management of an irrigation and drainage system, with the objective of ensuring that the input of resources, operational schedules, intended outputs and required actions proceed as planned. Following an introduction on this concept in Chapter 1, a framework on performance assessment is presented in Chapter 2. Chapter 3 then defines and discusses 23 recommended indicators covering the water balance, the environment and the economic aspects of the region. The method by which the indicators are used for operational and strategic performance assessment is discussed in Chapter 4, while the diagnostic use of the concept is presented in Chapter 5. The ultimate purpose of performance assessment is to achieve an efficient and effective project performance by providing relevant feedback to the project management at all levels. All related aspects of data management and communication with water users are illustrated in Chapter 6.
