Can Irrigation Technology Address Water Scarcity? (Podcast and Infographic)

Posted on November 14, 2019


GAO keeps a close eye on the latest technologies, but today we’re looking at a truly ancient one: irrigated agriculture. Despite dating back at least 5,000 years, irrigation technology continues to improve. Micro irrigation, for example, applies water close to the crop for high efficiency. And precision agriculture uses satellite imagery, wireless moisture sensors, and other tools to optimize irrigation scheduling.

Our new report tackles these questions. If you want an audio introduction, listen to our podcast with Tim Persons, GAO’s chief scientist:
