Population and economic growth are increasing the demand for water in all sectors, including agriculture. The aim of this research is to analyze the use of wastewater in agriculture; how it helps reduce drinking water shortages, mitigate climate change, and ensure food sovereignty, as well as the varieties of crops that can be produced. México is one of the main countries utilizing treated and untreated water; for example, in the Valle del Mezquital, Hidalgo, more than 90,000 hectares per year are irrigated. The process saves energy, production costs, and fertilizers, and reduces the environmental impact. For the study, AQUASTAT statistics were consulted for the main countries that use wastewater in their agricultural production; and CONAGUA statistics for the three districts of the Valle del Mezquital, Hidalgo. Besides, bibliographic review was conducted on the topic.
