The longstanding water-sharing agreement between the United States and Mexico is under increasing strain due to a severe drought in northern Mexico, particularly affecting the region of San Francisco de Conchos, which has experienced 30 months without rainfall. The U.S. government accuses Mexico of violating the treaty terms, while Mexican officials argue that current environmental conditions make compliance impossible. This escalating dispute has been described as a 'water war' between the two neighbors. Concurrently, both countries have taken steps to address environmental concerns by signing a memorandum of understanding focused on healthcare and environmental issues in the Tijuana-San Diego region, aiming to reduce decades-long pollution caused by wastewater discharges into the Tijuana River.
