| Abstract: | This paper attempts to identify the critical elements associated with the introduction and management of the practice of Rotational Irrigation in Taiwan, and thus to shed some light on the basic requirements for its successful adoption. While the emphasis is on this specific practice we believe it has implications for the transfer of other technologies in which physical, biological and managerial factors interact importantly.Seven irrigation associations in Taiwan were studied to identify the external conditions and system characteristics that are necessary for a successful change from continuous to rotational irrigation. Three external essentials are identified: (1) a water deficit approximating 25 percent of normal practice in the area; (2) political commitment to the change; (3) adequate financial resources for implementation and subsequent operation. Two system characteristics considered essential are: (1) physical facilities that provide for control and measurement to the level of farmer group responsibility; and (2) management patterns that provide a well-organized operating group and effective communication between the farmers and system personnel, resulting in a responsive plan of operation.Specific adaptations of the Taiwan practices to the local conditions will be necessary before effective transfer of this technology can take place elsewhere. |
