The technical and allocative efficiency of broadacre farmers in a southern region of Western Australia is investigated over a three-year period. Applying data envelopment analysis (DEA) and stochastic frontier analysis (SFA) reveals there is some inefficiency in each year, which decreases over time. The distributions of technical efficiency in each year are positively skewed toward higher effic...

groundwater is one of the common resources in varamin plain, but due to over extraction it has been exposed to ruin. this phenomenon will lead to economic and environmental problems. on the other hand, the world is expected to face with more stochastic events of water supply. furthermore, incorporating stochastic consideration of water supply becomes more acute in designing water facilities. th...

abstract one of the technologies that deal with efficient use of water is sprinkler irrigation systems. if farmers are to continue the use of sprinkler systems which may be crucial in agricultural development, educational programs should be tailored to their needs. therefore, the main purpose of this study was to analyze educational needs of farmers equipped with sprinkler irrigation. furthermo...

in many european states such as spain and italy there has been a significant growth of organic utilizable surface as a consequence of both a change in the model of agricultural production and also in order to satisfy arising demand of organic food. the purpose of this research was to investigate the level of technical, allocative and economic efficiency in italian olive farms with two different...

concern over the depletion of natural resources in general, and water scarcity in particular, has stimulated the development and implementation of some policies aimed at changing farmers' behavior in terms of conserving water. in this regard, government has recently begun to invest on researches supporting the technical solutions on conserving water in the agricultural sector as the bigges...
