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...

A positive mathematical programming model was constructed in this study to assess theeffect of three water pricing scenarios on Teboulba’s agricultural production systems.The effects of these scenarios were estimated for three groups of farmers from three irrigated districts. Results show that...

The paper aims to investigate the economies of scale of Water Users’ Associations (WUA) inTunisia. During the last years there has been a lot of discussion in Tunisia about the optimal sizeof WUAs, which allows more efficient management of the water resources at the local level. Inthis work we...

L'objectif de cet article est de calculer l'efficacité économique et environnementale liée à l'utilisation des eaux souterraines dans les petits périmètres irrigués de la Tunisie. L'impact environnemental pris en compte dans notre étude est le niveau d'épuisement de l'eau dans les...

Recent studies on the economics of agricultural water management in Tunisia report a low water productivity of some presently widely cultivated crops such as durum wheat. The objective of this study is to estimate water productivity and marginal value of irrigation water applied to durum wheat...

This study employs stochastic DEA approach for measuring irrigation water efficiency of wheat farms in irrigated areas of Chbika (Central Tunisia). Data was collected from 170 wheat farms during 2010-2011cropping season. The empirical results show that the average water use efficiency calculated...

This paper assesses the economic value of changes in the attributes of farmers’ irrigation water property rights in Tunisia. Changes on attributes generated by the transfer process of the property rights from the collective to the individual level in addition to changes in “constitutional”...

This study aims first to measure the farm specific irrigation water use efficiency (IWUE), through non parametric DEA model; and second to evaluate the potential irrigation cost reductions and identify the main factors causing variations in IWUE among the sample farms. Cross sectional data...

The paper aims to investigate the economies of scale of Water Users’ Associations (WUA) in Tunisia. During the last years there has been a lot of discussion in Tunisia about the optimal size of WUAs, which allows more efficient management of the water resources at the local level. In this work...
