To reduce water scarcity and drought impacts on society, many countries are attempting to impose extraction caps and reallocate available water resources. This is particularly challenging in agricultural systems where extraction points for irrigation use are diffused and difficult to regulate. To increase compliance to extraction caps, France has opted for decentralised allocation regime where agricultural users within the same hydrological unit share a common license to extract. The agricultural user group must then share the available water between irrigators while complying. No market mechanism is used.
This talk will present some of the rules designed by these user groups and will discuss the extent to which the French model is achieving an effective control on agricultural extraction in coherence with the spatial and temporal variability of water resources. An evaluation of their equitable and efficient nature will also be highlighted.
