Price Water Estimation in the Tancítaro Area (Mexico)

Abstract

: T he state of Michoacán stands out for its fruit production, mainly Hass Avocado (Persea americana). These orchards consume up to 5.2 times more water than the same area of a natural forest. The water used for these orchards belong to the inhabitants of the Upper Basin. The overexploitation and devastation of the forests have provoked the reduction of water availability for agricultural uses. We propose to make an approximation to the price that could be applied if the public administration makes the necessary improvements to ensure availability for farmers, in the future. We have created an artificial water market. Experts in agriculture have expressed their opinion using linguistic label. The use of hesitant fuzzy numbers has allowed the consideration of some kind of hesitance that has appeared during this work. Finally, the use of Ordered Weighting Average has allowed the aggregation of the information. As a result, we have obtained a fuzzy water demand and a fuzzy water supply curve. The intersection of both curves has allowed to get a water price of 0.54 $ m -3
