An analytical review of irrigation efficiency measured using deterministic and stochastic models

Several conclusions were drawn and discussed in this document. Of the thirty-two studies analysed, 87.5% determined efficiency using deterministic methods. Of these, the most frequently used methodology was DEA. These studies led to the conclusion that in general, farms are considerably inefficient with respect to water use, and some factors can contribute to its improvement, such as agricultural training, good crop choice, adoption of an extension advice service, not fragmenting the land or having larger farm sizes, a high education level, installing localized irrigation, being owners-operators and having access to better credit opportunities.
