IRRI, together with Plant Research International of Wageningen University and Research Centre (WUR-PRI; The Netherlands), organized a thematic workshop on water-wise rice production held 8-11 April 2002 at the IRRI, Los Baños, Philippines. The objectives were to present and discuss the development, dissemination, and adoption of water-saving technologies at spatial scales ranging from the field to the irrigation system. The workshop brought together scientists and irrigation system managers from several consortia and projects examining water scarcity in rice production—the Water Workgroup of the Irrigated Rice Research Consortium, the Rice-Wheat Consortium, and the projects “Water-Less Rice, Growing More Rice with Less Water, and Ground Cover Rice Production Systems. Participants created the International Platform for Saving Water in Rice (IPSWAR). The platform's purpose is to be a mechanism to increase the efficiency and enhance the coherence of research on water savings in rice-based cropping systems in Asia. This book contains 28 papers presented at the workshop on topics of intermittent irrigation, System of Rice Intensification (SRI), aerobic rice, rice-wheat, physiology, and breeding, and irrigation systems.
