TORRES-SOMBRA, Jesús  e  GARCIA-SALAZAR, José Alberto. Water Usage in Northern Sinaloa: Allocating the Resource to Consumers. Tecnol. cienc. agua [online]. 2015, vol.6, n.1, pp.167-173. ISSN 2007-2422.

Population growth and an increase in agricultural, livestock, industrial and commercial activities in northern Sinaloa have increased the demand for water. To determine the allocation of water to consumers, a spatial and intertemporal equilibrium model was validated for 2010, which includes demand functions and fixed supply. The results indicate that when water is scarce demand should decrease in the sector with the lowest value-in-use, such as agriculture, and should not change in sectors with a high value, such as the residential sector. A 10% reduction in the availability of water stored in dams would decrease consumption in Irrigation Districts 075 and 076 by 271 and 54 hm³ with respect to values from 2010, respectively, while consumption would not change significantly for livestock, residential, industrial and commercial activities. To decrease water consumption in the districts, the price needs to increase 82.7 and 70.0%, respectively.

Palavras-chave : Agriculture sector; livestock; residential; commercial and industrial; water price; spatial equilibrium and intertemporal model.
