In this paper, farm level technical efficiency of production and its determinants are investigated in a sample of 51 cereal producing farms located in the main cereal production region in Tunisia using a stochastic frontier production model. Empirical findings show that labor input factor...

This paper investigates the nonparametric analysis of technology under non-convexity. The analysis extends two approaches now commonly used in efficiency and productivity analysis: Data Envelopment Analysis (DEA) where convexity is imposed; and Free Disposal Hull (FDH) models. We argue that, while...

In this workshop the participants identified five priority areas of concern relative to sustainable management of groundwater irrigation by farmers:1) aquifer drawdown; 2) FMIS groundwaterwater support services, 3) management problems under water-surplus conditions; 4) management problems under...

Aset of simulations were used to estimate the impact of improvements in cattle breeding efficiency and other management factors on gross margins in extensive pastoral systems in Western Australia. The simulations showed that gross margin was an increasing function of breeding rates, but age at...

Using a bio-economic model, H2OBeef, that includes traditionally considered parameters associated with running a beef feedlot but also incorporates aspects associated with water, changes that can alter water consumption and or price are examined. The results indicate that when water does not...

In the context of sustainable consumption buying local produce could support environmentally friendly production from the local economy. Our study estimates the preference weights that local consumers assign to some milk attributes including local origin and the influence on choice of a local...
