Water productivity in agriculture: limits and opportunities for improvement.

Book cover for Water productivity in agriculture: limits and opportunities for improvement.

Description

This book presents a state of the art review of the limits and opportunities for improving water productivity in crop production, focusing on both irrigated and rain-fed agriculture. It provides concepts, methodologies, constraints and examples drawn from a wealth of experience from developing and developed countries. It demonstrates how efficiency of water use can be enhanced to maximize yields. ...

Improving water productivity in the dry areas of West Asia and North Africa.

In the dry areas, water, not land, is the limiting factor in improving agricultural production. Maximizing water productivity, and not yield per unit of land, is therefore a better strategy for on-farm water management under such conditions. This chapter highlights the major research findings at the International Center for Agricultural Research in the Dry Areas regarding improving the water productivity of its mandate crops of wheat, barley, lentils, chickpea and faba bean. It is shown that substantial and sustainable improvements in water productivity can only be achieved through integrated farm-resources management. On-farm water-productive techniques, if coupled with improved irrigation-management options, better crop selection and appropriate cultural practices, improved genetic make-up and timely socio-economic interventions, will help to achieve this objective. Conventional water-management guidelines, designed to maximize yield per unit area, need to be revised for achieving maximum water productivity instead. A case study from Syria shows the applicability of this option. It illustrates that, when water is scarce, higher farm incomes may be obtained by maximizing water productivity than by maximizing land productivity.
