Summary: | The objective of this study is to calculate the technical and water use efficiency in the irrigated scheme Jijel-Tahir, East of Algeria, using the Data Envelopment Analysis (DEA) method. The DEA was also used to simulate the effect of different levels of water quotas on the improvement of these indicators. The first part of the paper presents a typology of farms in the study area based on the method of principal component analysis combined with a hierarchical ascending classification. The results show that the average technical efficiency of the farmers in the sample is about 80% while the average water use efficiency is around 61%. The application of quotas for water use may lead to improving the irrigation water use efficiency by up to 15%. Keywords: Data Envelopment Analysis, irrigation water, efficiency, Algeria. L'objectif de cet article est d'analyser l'efficacite technique et d'usage de l'eau d'irrigation dans le perimetre irrigue Jijel-Taher dans l'Est de l'Algerie, ainsi que l'effet de differents niveaux de quotas d'eau sur l'amelioration de ces indicateurs. La premiere partie de l'article presente une typologie des exploitations maraicheres de la region d'etude en se basant sur la methode d'Analyse en composantes principales combinee a une classification ascendante hierarchique. La methode DEA (Analyse par Enveloppement des Donnees) a ete utilisee pour le calcul des efficacites. Les resultats ont montre que les scores d'efficacite technique moyenne de l'echantillon sont de l'ordre de 80% alors que l'efficacite d'usage de l'eau est de 61%. L'application des quotas d'eau permettra une amelioration de cette derniere efficacite de l'ordre de 15%. Mots-cles: analyse par enveloppement des donnees, efficacite, eau d'irrigation, Algerie.
