- W2940897783 abstract "La reglementation francaise remet a plat les autorisations de prelevements d'eau pour l'irrigation, dans un objectif de retour a l'equilibre ressources/besoins d'ici 2014 a 2021. Dans le sudouest, ou une majorite du territoire est consideree comme deficitaire en eau mais ou l'irrigation est tres presente, cette reforme impliquera une baisse des volumes actuellement attribues. La presente etude a eu pour objectif d'evaluer l'impact de cette baisse sur l'economie agricole. Elle a ete effectuee a l'echelle de six territoires en simulant les pertes en marge brute ou en excedent brut d'exploitation, avec ou sans mesures d'accompagnement. La combinaison de ces mesures permet, dans la majorite des cas, de reduire tres significativement voire d'annuler ces pertes. Parmi ces mesures, les plus efficaces sont la creation d'ouvrages de stockage et l'allocation prioritaire de quotas d'eau aux cultures a forte valeur ajoutee (arboriculture, maraichage, semences). / Water withdrawal policy for irrigation is reformed by the French legislation for a return to a balance between resources and needs in 2014 to 2021. Irrigation is largely developed in south-western France, where most of the territory faced structural water deficits. This policy change will decrease the available water for irrigation. The aim of this study was to assess the impact of this reform on the farming economy. It has been conducted on six watershed where economic losses have been simulated, using or not support measures. For most of cases, the combination of these measures lead to a significant decrease or a cancel of the losses. Among these measures, the most effective are the investment in water storage, and the prior water reallocation for high added value crops (tree crops, vegetable growing, seeds crops)." @default.
