Water and energy are critical drivers for life as well as agricultural production. Agricultural processes combine water and energy resources to produce food and fibre crops for human and animal consumption. The current level of global growth and development achieved can be attributed to the quality and quantity of water and energy being consumed (Hellegers et al., 2008). However, the consumption of these resources is not without consequence. It is therefore imperative that we consider the sustainability of these precious but limited resources in relation to agriculture, if we are to continue to provide food for the global population and to achieve the required gains in production necessary in the future.
