Mexico's barley production is being challenged by climate change-induced drought, with the main producing region, the Altiplano, seeing reduced rainfall and yields. This could negatively affect the national brewing industry, which accounts for 1.6% of Mexico's GDP and supports over 700,000 jobs. Efforts are being made to adopt regenerative cultivation methods and introduce new technologies to sustainably farm under extreme weather conditions. The Cultivando un México Mejor initiative by CIMMYT and Heineken is showing positive results in water savings and increased yields.
