Última Measuring Irrigation Water Efficiency with a Stochastic Production Frontier: An Application for Citrus Producing Farms in Tunisia AgEcon Dhehibi, Boubaker; Lachaal, Lassaad; Elloumi, Mohamed; Messaoud, Emna B.. The objective of this paper is to propose an alternative measure of irrigation water efficiency based on the concept of input- specific technical efficiency, which contracts with measures previously used in the literature. The proposed methodology is applied to a randomly selected sample of 144 citrus growing farms located in Nabeul (Tunisia). A stochastic production frontier approach, based on Battese and Coelli’s (1995) inefficiency effect model, is used to obtain farm-specific estimates of technical and irrigation water efficiency. In addition, a second-stage regression approach is used to identify the factors influencing irrigation water efficiency differentials across citrus growing farms. Results indicate that technical efficiency ranges from a...

Ano: 2008 URL: http://purl.umn.edu/52166 Measurement and Sources of Technical Inefficiency in the Tunisian Citrus Growing Sector AgEcon Dhehibi, Boubaker; Lachaal, Lassaad; Elloumi, Mohamed; Messaoud, Emna B.. This paper investigates farm level technical inefficiency of production and its determinants in a sample of 150 citrus producing farms in Tunisia using a stochastic frontier production function approach applied to cross section data. Results indicate that technical efficiency of production in the sample of citrus producing farms investigated ranges from a minimum of 26.84% to a maximum of 97.98% with an average technical efficiency estimate of 86.23%. This suggests that citrus producers may increase their production by as much as 13.77% through more efficient use of production inputs. Further, the estimated coefficients in the technical inefficiency model indicate the positive effect on technical efficiency of the share of productive trees, the...

Ano: 2007 URL: http://purl.umn.edu/9391 Measuring irrigation water use efficiency using stochastic production frontier: An application on citrus producing farms in Tunisia AgEcon Dhehibi, Boubaker; Lachaal, Lassaad; Elloumi, Mohamed; Messaoud, Emna B.. 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...
