The National Water Commission (Conagua) reported that Mexico City is classified as “abnormally dry”, which, according to the Federal Government, “is a condition of dryness, is not a category of drought”.

With this, the country's capital joins nine other entities in the north and east of the country, including: Nuevo León, Tamaulipas, Guanajuato, Hidalgo, Veracruz, Puebla, Tlaxcala, Oaxaca and Chiapas. However, the only mayors that are saved from being in this condition are: Azcapotzalco, Venustiano Carranza and Gustavo A. Madero.

According to drought categories, this can mean the beginning or end of a dry period, that is, in the short term it can cause delayed planting of annual crops, limited growth of crops or pastures and there is a risk of fires. In the long term, water deficit may persist, pastures or crops may not fully recover.

In this context, the mayors of Mexico City are obliged to carry out a climate change program, according to sections II and XI of article 8 of the Capital's Law on Mitigation and Adaptation to Climate Change and Sustainable Development, published by the Head of Government, Claudia Sheinbaum.

On the other hand, during the forum Desalination of Seawater and its Use, the head of the Commission, Germán Arturo Martínez Santoyo, indicated that, given the great availability of seawater in Mexico, desalination is an alternative to address water scarcity. However, he pointed out that it should be taken into account that these projects require high energy demand for their production, high operating and maintenance costs, as well as adequate disposal of the generation of reject water

It is worth mentioning that recently, Conagua also reported that the storage of the three main dams of the Cutzamala system, El Bosque, Valle de Bravo and Villa Victoria, which supplies part of the metropolitan area of the Valley of Mexico decreased by 1.2 per cent in just one week and stood at 51.8%.

In the case of the El Bosque dam, located in Zitácuaro, Michoacán, it decreased by 3.5% compared to the previous week and the storage level stood at 44.2%, with 89.5 million cubic meters (Mm3).
