Point of view - The search for maximum water use efficiency, an objective not to be disconnected from an integrated vision of the production system

Drip irrigation, and more subsurface drip irrigation, are particularly popular techniques for irrigating crops in regions where water resources are a major constraint. However, as François Gontard of BRL Exploitation shows, installing this equipment does not guarantee maximum water use efficiency, only highly specialised irrigators are able to fully exploit its potential.
