摘要
In many countries today, irrigation systems have been transferred to the water user associations (WUAs). Accordingly, it is believed that the performance of the irrigation systems is dependent on the performance of the WUAs. In this study, the performance of participatory irrigation management (PIM) over time is assessed with regard to the Kestel WUA serving a wide area of Turkey's Aegean coast. Data relating to the WUA is obtained from both the State Hydraulic Works and WUAs' own records. In addition, two surveys have been carried out with the members of the WUA with an 8-year interval between them. Data have been analyzed within the framework of selected irrigation performance criteria and indicators. The non-parametric Mann-Whitney U test was used to compare the perceptions of the farmers on the WUA at different survey periods. A Logit model was estimated to evaluate the relationship between the irrigation problems and the level of satisfaction from the WUA. The performance of the WUA with the indicators of utility, productivity, sustainability and financial efficiency was found to be positive; while the performance of adequacy was identified as poor. The farmers were generally satisfied of the WUA's operation, with their level of satisfaction improving over time. On the other hand, the farmers were not fully convinced that they had input with the system management. The initial design of the channel system and its maintenance were identified to be the key factors affecting user satisfaction. Overall, the Kestel WUA may be considered a successful example, thus supporting a promising future for PIM. Yet improved control and farmer education is needed for a superior performance of all indicators; and further enhanced farmer participation in management should be achieved in order to raise the level of farmer satisfaction.
