SALAZAR-MORENO, Raquel; ROJANO-AGUILAR, Abraham  and  LOPEZ-CRUZ, Irineo Lorenzo. Water Use Efficiency in Controlled Agriculture. Tecnol. cienc. agua [online]. 2014, vol.5, n.2, pp.177-183. ISSN 2007-2422.

Many regions in the world have reached water usage limits, resulting in surface and groundwater overexploitation and its negative environmental impacts. In countries that depend on groundwater for irrigation, such as Mexico, excess water extraction has depleted the water table to an alarming level. Also, 77% of available water in Mexico is used in agriculture, for this reason it is important to increase water use efficiency in this sector. This brief review is about modern agricultural techniques to increase water use efficiency, such as environmental control, closed hydroponic systems and semiclosed greenhouses.

Keywords : Environmental control; hydroponics; closed systems.
