This paper proposes an alternative measure of irrigation water efficiency based on the concept of input-specific technical efficiency. It uses a stochastic production frontier approach, based on Battese and Coelli’s (1995) inefficiency effect model, to obtain farm-specific estimates of technical and irrigation water efficiency, and a second-stage regression approach to identify the factors that influence irrigation water efficiency differentials. This methodology was applied to a sample of 144 citrus farms in Nabeul, Tunisia. Technical efficiency varies widely, suggesting that these citrus farmers could increase their production by as much 33% by using inputs more efficiently. Mean irrigation water efficiency is similarly variable, and on average below... |
