|
|---|---|
| This chapter discusses the importance of the management of water supply within rainfed agricultural productions systems in already dry regions that face the prospect of further decreasing rainfall from climate change. It examines the interactive effects of water supply with high temperature and rising atmospheric CO2 concentrations on grain production and quality. The chapter explores the use of simple models of transpiration efficiency and radiation use efficiency and how phenotypic crop ideotypes might help achieve the breeding and agronomic management objectives of maximizing the available water resources to maintain crop productivity. It draws examples from Australia and Spain. The examples of adaptation strategies to drought and water conservation issues from Australia and Spain are representative of typical dry and semi?arid regions where cropping is a dominant and economically important activity. Water is essential for crop production and its shortage significantly limits the productive levels that can be achieved. | |
