Résumé : | In Tunisia, the development of the irrigated cereal sector plays a key role in the mitigation of the fluctuation of the rainfed production and to ensure a minimum of production. However, the archived yields remain under the expected potential performance, and the water productivity is very low. Hence, this work aims to investigate the performance of the irrigated durum wheat activity and to identify eventual determinants to improve the water productivity. To reach the objective, a field survey was carried out with a sample of 555 farmers. We adopted a data envelopment analysis approach to assess the technical efficiency and water use efficiency. A Tobit model was estimated to identify determinants of the technical performance. The results showed that the technical efficiency reached only 63%, which meant that farmers could increase the durum wheat yield from 3.5 tha−1 to 4.8 tha−1. The water use efficiency reached only 30%, which translates to an unwise use of the water resource. The results also showed an eventual improvement of the water productivity by more importantly saving the irrigation water rather than optimizing the production. To improve the performances, the results revealed some key determinants that could be taken into account by policy makers to implement appropriate strategies. |
