The Productivity Commission staff working paper, 'Responsiveness of Demand for Irrigation Water: A Focus on the Southern Murray-Darling Basin', was released August 2004. This paper explores the determinants of the elasticity of demand for irrigation water. It focuses on three main irrigated industries - rice, dairy and horticulture - to gain a greater understanding of the value that farmers place on water as an input. This paper provides detail relating to farm decision behaviour and biophysical production realities faced by irrigators in the southern Murray-Darling Basin. The views expressed in this paper are those of the staff involved and do not necessarily reflect those of the Productivity Commission.
