ESTIMATION OF THE FOREST AREA REQUIRED FOR WATER SUSTAINABILITY OF AVOCADO IN THE SOUTH OF THE STATE OF MEXICO

Abstract

This study analyzes the relationship between forest cover and water supply required for avocado (Persea americana) cultivation, in order to determine a balance between these two; based on the “Water Yield” model, which makes it possible to quantify water production in a specific watershed. The results obtained enable establishing the amount of forest needed to provide adequate water supply for avocado, in the context of the growing demand for this agro-food product worldwide. In this sense, it is possible to outline the guidelines for reflecting on changes in land use in the territory, based on the switch to avocado cultivation, so that an alteration in water availability can be avoided. We conclude that in the southern region of the State of Mexico, considering the regulatory impact of forest, it appears that the proportion required to provide water to one hectare of avocado is 1.35 ha.
