GARCIA-SALAZAR, José A.; GUZMAN-SORIA, Eugenio  e  FORTIS-HERNANDEZ, Manuel. Water demand and distribution in the Comarca Lagunera, México. Agrociencia [online]. 2006, vol.40, n.2, pp.269-276. ISSN 2521-9766.

To determine the price increase of water in the agricultural, livestock, residential and industrial sectors of the Comarca Lagunera that will make it possible to reduce the extraction of underground water, a spatial and intertemporal equilibrium model was validated, which considered demand functions and fixed supplies. Results indicate that in the period 2001-2003, the average annual water demand was 872.5, 539.2, 62.8, 44.2 and 28.9 million cubic meters (hm3) in the pumped and surface irrigation agriculture, residential, livestock and industrial sectors. Of this demand 65.3% (1013.4 hm3) was supplied with underground water. A reduction of 10% in the underground water extractions could be achieved by increasing the price 98.6 and 21.5% in the pumped irrigation agriculture and industrial sectors, with respect to the average prices of 2001 to 2003, given that such an increase would reduce the demand by 99.8 and 1.4 hm3 in these sectors.
