How do farmers react to varying water allocations? An assessment of how the attitude to risk affects farm incomes

Abstract

A risk farmers have to cope with is annual changes in the availability of irrigation water. In this paper the relationship between irrigation water allocated to farmers and the incomes they derive in the Coleambally Irrigation Areas (CIA) in Australia is quantified. It is shown empirically that farmers reduce the area cropped when faced with reduced water availability. Increasing the availability of water does not necessarily lead to more stable (less volatile) income streams, as it offers the opportunity to include more water intensive, yet also more risky, crops in the cropping pattern (e.g. rice). However, it does lead to an overall increase in incomes. It was found that rice is the domin..
