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
Tancítaro地区(墨西哥)水价估算
Michoacán州以其水果生产而闻名,主要是哈斯鳄梨(美洲鳄梨)。这些果园消耗的水比同样面积的天然林多5.2倍。这些果园所用的水属于上盆地的居民。对森林的过度开发和破坏导致了农业用水的减少。我们建议,如果公共行政部门在未来作出必要的改进,以确保农民能够获得所需的价格,我们可以对其进行近似计算。我们创造了一个人工水市场。农业专家用语言标签表达了他们的观点。犹豫模糊数的使用允许考虑在这项工作中出现的某种犹豫。最后,使用有序加权平均法实现了信息的聚合。得到了模糊需水量和模糊供水量曲线。两条曲线的交点使得水价为0.54美元
