Field water management to save water and increase its productivity in irrigated lowland rice
Abstract Rice production in Asia needs to increase to feed a growing population whereas water for irrigation is getting scarcer. Major challenges are to (i) save water; (ii) increase water…
ORYZA2000 : modeling lowland rice
ORYZA2000: modeling lowland rice is the successor to a series of (lowland) rice growth simulation models developed by IRRI and Wageningen University and Research Centre (WUR) in the early to…
Yield and water use of irrigated tropical aerobic rice systems
Abstract Increasing water scarcity necessitates the development of irrigated rice systems that require less water than traditional flooded rice. In irrigated aerobic rice systems, rice grows in…
Effect of water-saving irrigation on rice yield and water use in typical lowland conditions in Asia
Abstract With decreasing water availability for agriculture and increasing demand for rice, water use in rice production systems has to be reduced and water productivity increased. Alternately…
Rice production in water-scarce environments
Rice production in Asia needs to increase to feed a growing population. Though a complete assessment of the level of water scarcity in Asian rice production is still lacking, there are signs that…
The 'School of de Wit' crop growth simulation models: a pedigree and historical overview.
A pedigree of the crop growth simulation models by the ‘School of de Wit’ is presented and it is shown how changing research goals and priorities over the years have resulted in the evolution of a pedigree of models that are similar in philosophy but differ in level of complexity, the processes addressed and their functionality.

Irrigated ‘aerobic rice’ is a new system being developed for lowland areas with water shortage and for favorable upland areas with access to supplementary irrigation. It entails the cultivation of…
Rice and Water
The Comprehensive Assessment of Water Management in Agriculture (CA) seeks answers to the question of how freshwater resources can be developed and managed to feed the world's population and reduce…
More Rice, Less Water—Integrated Approaches for Increasing Water Productivity in Irrigated Rice-Based Systems in Asia
Assessment of technologies and systems for reducing water inputs and increasing water productivity at spatial scale levels from plant to field, to irrigation system, and to agro-ecological zones concluded that, while increasing the productivity of irrigated rice with transpired water may require breakthroughs in breeding, many technologies can reduce water inputs at the field level and increase field-level water productivity.
Adoption and economics of alternate wetting and drying water management for irrigated lowland rice.
To counteract the increasing unavailability of water for agriculture, the International Rice Research Institute (IRRI) and its national agricultural research and extension system (NARES) partners…
