Better management of water consumption and irrigation schedule in irrigated agriculture is essential in order to save water resources, especially at regional scales and under changing climatic conditions. In the context of water management, the aim of this study is to monitor irrigation activities by detecting the irrigation episodes at plot scale ...
Ce rapport du ministère français de l’Agriculture et de l’Alimentation porte un regard prospectif sur l’avenir de l’irrigation agricole en France dans un contexte de changement climatique. Il s’appuie sur une série d’études sur le climat (Climator, Climsec, cinquième rapport du GIEC [Groupe d’experts intergouvernemental sur l’évolution du climat]),...
The aim of this work is to calculate and compare the economic efficiency indices of irrigated farms and the level of optimisation of irrigation water used for the main crops of the Gharb area. To this end, a Data Envelopment Analysis (DEA) model was used to calculate efficiency indices. The survey covered 49 farms with different crop systems (veget...
La loi sur l'Eau et les Milieux Aquatiques de 2006 impose, pour les aquifères intensément exploités par l'usage agricole, la mise en place d'Organismes Uniques de Gestion Collective chargés de faire respecter le volume prélevable alloué à l'irrigation. Ce travail soulève des questions à court terme concernant l'établissement des règles de fonctionn...
The interest of irrigation for durum wheat is often questionable because of possible spring rainfalls in the SE of France. In this study cropping strategies i.e. plant density (PD), sowing date and irrigation management were analysed for improving irrigation water productivity (IWP). An experiment was carried out for calibrating and validating PILO...
In the environmental field, water management provides examples of the move towards participative democracy. Indeed, French water policy promotes participative river basin management settings. Such settings place different forms of knowledge in contact with each other, and raise the issue of assembling this plurality within the decision-making proce...

Le déséquilibre entre l'offre et la demande en eau au cours des 50 prochaines années va aller en s'accentuant, en particulier dans les régions situées dans le pourtour méditerranéen sous la contrainte du changement climatique et de la pression démographique. C'est notamment le cas dans la plaine du Roussillon, caractérisée par une forte croissance ...
This paper proposes an optional target-based mechanism to improve the management of groundwater withdrawals when farmers’ behavior is imperfectly monitored. It combines a classical ambient tax (a blind truncheon), paid by the group of farmers when the water table level falls below a pre-defined target, with an optional individual contract that enab...
