Última Demand for Irrigation Water for Pistachio Production from Depleting Groundwater Resources: Spatial Econometric Approach AgEcon Jaghdani, Tinoush Jamali; Brümmer, Bernhard. Depletion of groundwater resources is an international problem, and groundwater is probably the world’s most extracted raw material. The agriculture sector is one of the biggest users of groundwater resources for irrigation activities, and it plays an important role in the depletion of these resources. The estimation of demand function for groundwater resources is the first step toward any policy recommendation in this field of research. However, only scarce attention has been given to empirical studies of the demand structure of groundwater resources by the help of econometrics and considering the quality of the resources in the context of a single aquifer. Therefore, an empirical estimation of the demand function for individual users which considers...

Ano: 2011 URL: http://purl.umn.edu/114457 Analysis of Technical Efficiency and Varietal Differences in Pistachio Production in Iran Using a Meta-Frontier Analysis AgEcon Boshrabadi, Hossain Mehrabi; Villano, Renato A.; Fleming, Euan M.. This paper reports on an analysis of technical efficiency and varietal differences in pistachio production in Iran. A random sample of 475 farmers was selected from the province of Kerman in 2003 and 2004. In this study, farmers are classified into three groups according to the variety of tree they planted. The three main varieties of pistachio trees planted are Kalleh- Ghuchi, Fandoghi and Akbari. The technical efficiency indices are computed using three approaches. First, a standard stochastic production frontier was employed using pooled data. Secondly, stochastic frontier production functions were estimated for each variety (separately). Lastly, the meta-frontier approach was used because production varieties and technologies are expected to differ...
