Technological and Institutional Innovation in Irrigation

摘要

The main objective of the workshop was to examine the available technologies in irrigation and to ask whether they have been adequately and effectively exploited throughout the world -- particularly in developing countries. In the first section a review was made of changing roles in irrigation and of technology and research issues in irrigation. The conclusion of this section is that irrigation research has not kept pace with agricultural scientists who have dramatically changed the potential yields that can be obtained from good crop husbandry. The second section focused on the choice of appropriate technology. Non surface methods dominate the discussion. The third section reviewed research priorities. More research is urgently needed on the interface between agriculture and hydraulics in surface irrigation, and economic, social and institutional aspects of modern irrigation systems. The fourth section focused on transfer of technology.
