This paper suggests definitions of three elements essential to successful irrigation - water rights, infrastructure capable of delivering the service implied in the water right, and assigned operational responsibilities. Depending on whether the basic elements are promptly matched, systems are defined as 'functional' or 'dysfunctional.' The importance of interactions among these factors is illustrated through field examples. It is argued that performance analysis of dysfunctional systems is problematic, and functionality may be a prerequisite to significant improvements in performance. The definition of water rights, particularly as undocumented and unregulated usage develops, is likely to present the most difficult challenge to achieving functionality.

Outlines the IWMI Water Balance Framework, which identifies sources, uses and reuses of water. The framework will be of interest to those involved in the design of irrigation projects and in the formulation of improvements to existing infrastructure of operational rules. Managers of irrigation projects will also find it useful for interpreting water use efficiency, or for identifying interventions to improve the efficiency and sustainability of their projects.

Discusses the potential opportunities and pitfalls of introducing market forces into the process of water allocation. Proposes several preconditions for beneficial privatization of water allocation and argues for a more sophisticated form of analysis than that generally allowed by proponents of basic needs or of free market approaches.

Outlines IWMI's external and other comparative performance indicators that allow for analysis of irrigation performance across systems. The purpose of these indicators is to understand the current situation with respect to productive utilization of land and water, to compare relative performance of systems, and to identify where performance can be improved.

Inadequate funding for maintenance of irrigation works and emerging shortages of water are prevalent. The use of water charges to generate resources for maintenance and to reduce demand is widely advocated. Examples from other utilities, and from the domestic/industrial sectors of water supply suggest the approach could be effective. In developing countries, the facilities required for measured and controlled delivery of irrigation are rarely in place, and would require a massive investment in physical, legal and administrative infrastructure. To be effective in curtailing demand, the marginal price of water must be significant. The price levels required to cover operation and maintenance (O&M) costs are too low to have a substantial impact on demand, much less to actually bring supply and demand into balance. On the other hand, the prices required to control demand are unlikely to be within the politically feasible range. Furthermore, water supplied is a proper measure of service in domestic and industrial uses. But in irrigation, and especially as the water resource itself becomes constrained, water consumption is the appropriate unit for water accounting. This is exceptionally difficult to measure. An alternative approach to cope with shortage would focus on assigning volumes to specific uses—effectively rationing water where demand exceeds supply. This approach has a number of potential benefits including simplicity, transparency, and the potential to tailor allocations specifically to hydrological situations, particularly where salinity is a problem. Data from Iran are presented to support these contentions.

This study uses both farmer surveys and physical measurements to understand the impact RCTs have had on water use and water savings in the irrigated Rice-Wheat Zone of Pakistan's Punjab province. The findings show that field scale water savings achieved from RCTs is not necessarily equivalent to water savings at broader scales and may even result in an increase in overall water depletion.
