摘要：

Traditional analyses of irrigation performance, especially the concept of irrigation efficiency, can mislead planners and policy makers, especially as water availability at the river basin level becomes the primary constraint to agricultural production. Improving the productivity of water, not land, requires rethinking of some basic 'facts' about irrigation performance, new ways of managing, and may be contradictory to some recent trends in institutional reform.
