Avocado cultivation provides the State of Michoacan with an annual income of 33,848 million pesos, however, the process of harvesting avocados has a serious impact on the environment, said Alberto Gomez-Tagle Chavez, a researcher at the University of San Nicolas de Hidalgo in Michoacan.
According to the specialist, the change in land use, the erosion caused by the immoderate felling of trees, and the construction of 50 thousand water collection points interrupts the hydrological cycle in the area, preventing the normal collection, filtration, and storage of water.
Alberto Gomez, an expert from the Research Institute on Natural Resources of the UMSNH, stated in his article 'The risks for water in avocado cultivation', which was published by the Conacyt Informative Agency, that this monoculture has a really serous negative impact on the availability of water.
The most serious thing, he said, is that one hectare of avocado with 156 trees consumes 1.6 times more water than a forest with 677 shrubs per hectare. He also stated that there were different types of producers in the entity, some of which had a few trees in half a hectare of land and some of which had more than 150 or 200 hectares.
There are at least 158,000 hectares of quality avocados in Michoacan.
