Rehabilitation of Irrigation Distribution Systems: The Case of Jericho City
Efficiency enhancement in irrigation distribution system (IDS) contributes to substantial water savings. This paper aims to present the methodology and lessons learned from efforts to improve efficiency in the irrigation distribution system of Jericho City. This effort presents a new paradigm in water management in water scarce countries, which focuses on both supply and demand management rather than on supply augmentation. Converting the existing irrigation canal system to a pressurized pipe network carries out rehabilitation of IDS in Jericho City. Analysis of the new IDS is performed through computer simulation. Considerations and constraints for sustainable irrigation management are presented.
Performance Improvement Capacity Audit: A Methodology for Diagnosing Capacity to Improve Irrigation Performance
This paper presents an objective easy-to-use methodology for rapidly assessing the capacity of the m anagers and users of an irrigation system to respond positively to interventions to im prove performance, and for identifying the types of interventions likely to succeed. The 'Performance Improvement Capacity Audit' is based on five basic questions on system design, operations, data collection, management framework and the will to manage. It is applied retrospectively on five systems to demonstrate its potential usefulness. The methodology complements others which focus on assessing actual and potential system performance.
Water for sustainable development in the 21st century: a global perspective
Many arid and semi-arid countries are feeling water crisis already at present, and the problem will become more serious in the 21st century. Global water consumption will increase, 10-fold during this century, and the increasing trend will continue well into the 21st century. This Presidential Address to the International Water Reserves Association discusses the reasons for the water crisis, and the major water issues of the 21st century. Among those issues are water conservation and efficient use of water, water pricing and cost recovery, social and environmental considerations, institutional responses to better management, management of international water bodies and proper analytical frameworks.
