Barley is a niche crop—unless you’re a beermaker. To make sure it has consistent supply of the ingredient that keeps its revenue growing, AB InBev has developed a digital platform called SmartBarley. It uses weather data, in-field sensors, and satellite and drone images to help 18,000 farmers (in 11 countries, including the U.S. and India) avoid threats to their barley crops as well as reduce their environmental footprint. AB InBev is also partnering with farmers in Brazil’s northeast to battle that region’s extreme poverty. There, it brews beer with local cassava, injecting vitally needed revenue into the local economy.
