Desktop Review Of Groundwater Prospectivity For Irrigation In The Lower De Grey River Area, Don L. Bennett, John A. Simons

Resource management technical reports

The Department of Primary Industries and Regional Development (DPIRD) has identified priority areas in the Pilbara that warrant further investigation into their capacity for irrigated agriculture and related businesses. The De Grey River area is one of these.

The lower De Grey River area, upstream of the De Grey River Water Reserve, was identified by the Transforming Agriculture in the Pilbara (TAP) project for staged investigations of viability. Progression through these stages, each with increasingly detailed groundwater and soil suitability investigations, is dependent on prospectivity.

This document provides a summary of DPIRD’s initial desktop groundwater evaluation in the lower De …

Moving Beyond ‘More Crop Per Drop’: Insights From Two Decades Of Research On Agricultural Water Productivity, Meredith Giordano, Susanne M. Scheierling, David O. Tréguer, Hugh Turral, Peter G. Mccornick

Daugherty Water for Food Global Institute: Faculty Publications

Concern over increasing water scarcity has led to the introduction of the concept of agricultural water productivity and an emphasis on interventions to achieve ‘more crop per drop’. Yet, a strong debate continues on how the concept is to be defined and used. Drawing largely from the irrigation literature, the origins of the concept and its methodological developments are reviewed, and its use in applied work over two decades is discussed. Based on this analysis of conceptual and applied research, key insights into the concept’s contributions and limitations are presented, as well as opportunities for further refinements.
