1 Hanson, E. G.; El-Kady, M.; Litwiller, K. E.; Early, A. C.. 1984. Impact of turnout size and condition on water management on farms. Cairo: Egypt Water Use and Management Project. vi, 29p. (EWUP technical report no.71)
(Location: IWMI-HQ Call no: 631.7.6.2 G232 HAN Record No: H033)
The following report describes the legal irrigation throughout turnouts to mesgas and reviews the design assumptions, legal implications and current utility of the existing methods in Egypt. The legal limitations currently imposed upon the turnouts, based on specific site measurements, are presented, together with the responses from the Ministry of Irrigation and farmers to the inadequacies of the current turnouts. Data collected from the field sites indicates the necessity of increasing the size of turnouts in accordance with irrigation demands for the season and crops grown throughout Egypt. The recommended larger capacity turnouts with adjustable gates includes the design modification requirements of modified inlet shapes and provision for trash guards. These larger gated turnouts will require an irrigation technician to assume the responsibility of the current gatekeeper function and to interface with the farmers regarding their irrigating scheduling. In addition to recommendations regarding closer management between the irrigation technician and the farmers, it is suggested that training centers be established to assist in the development of water distribution management methods between the irrigation engineers and the water user associations.

Examples are drawn from the Indus Basin to explain why on-farm water management problems restrict the output of agricultural products in many LDCs. Data are presented to illustrate the low level of water management knowledge of both the farmers and the current extension agents. Examples of the level of corruption and its effect on the operating system are illustrated. Several requirements that must be met before a large-scale irrigation scheme will actually increase the welfare of LDC farmers are presented.

A specially designed irrigation water management calendar was used as an information source for farmers in a system-wide irrigation management study in the Lower Talavera River Irrigation System. The study was designed to determine ways to achieve an equitable supply of irrigation water throughout the system. The calendar was based on the monthly sequence of farming activities and had drawings and captions emphasizing positive irrigation behavior and improved water management practices. It was found that 75% of farmer irrigators learned new water management practices from the calendar. 20% used the calendar as a pattern or guide far farming activities and 16% used it to improve water management. Only 8% of the farmers admitted using it just to record farm activities. Negative behavior and source credibility of farmers were the only two variables found to be significantly associated with calendar effectiveness. Farmers with a high level of effectiveness tended to exhibit low negative behavior. Similarly, farmers who rated the calendar's effectiveness as high perceived the irrigation agency personnel as a highly credible source of information.

Farmers and their local organizations are not only the end receivers in the technology transfer process but are also means of effective horizontal transfer of technologies to other farmers. Farmer organizations are a requisite for the maintenance of many improved technologies which require collective action. The Pakistan case study describes the importance of this concept and the need for irrigation specialists to understand and utilize local farm organizations for water management improvement programs. The unique research-development process developed by Colorado State University in Pakistan has built- in mechanisms for the transfer and maintenance of technologies.
