| 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 collected from a sample of 75 farms participating in the WaDImena project in Nadhour region (northern Tunisia) was used for this aim. The results showed that the average level of IWUE across the farm sample was around 61.2% under variable returns to scale (VRS) assumption. However, the estimated mean irrigation water technical cost efficiency (ITCE) is much higher than IWUE. Farmers would be able to reduce their actual cost by 5% under VRS by adjusting irrigation water... |

| In terms of value added, olive oil is one of the most important agricultural commodities in Tunisia. It is also the most important agricultural export commodity. Tunisia ranks second to Spain in world olive oil exports. Currently these exports account for about 20 percent of total export earnings of Tunisia. This is equivalent to about 40 percent of total agricultural export earnings. Tunisia is by far the largest olive oil producing country in North Africa and the Middle East and ranks sixth among the world's producers of olive oil. Considering the adaptability of the olive tree to the climate and soil conditions of Tunisia, olive culture is expected to maintain its importance in Tunisian agriculture. However, the economic benefits which could be... |
