Abstract
Rice, a staple food for over 70% of Asians, is also the single biggest user of water, requiring 2‐3
times more water per unit of grain produced than crops such as wheat and maize. With
growing populations, increased urbanisation and environmental degradation, the supply of
fresh water is depleting. Recognising the water constraints to rice yield, the aim of the project
entitled ‘Developing a System of Temperate and Tropical Aerobic Rice (STAR) in Asia’ was to
develop water‐efficient aerobic rice technologies. This paper highlights the success of that
project.
