Why everything you think you know about irrigation technology is wrong, and what to do about it.
Irrigation is pivotal to the global agricultural economy. Though only 16% of the world's croplands are irrigated today, those lands produce 36% of the global annual yield. In developing countries, irrigation increases crop yields by 100 to 400%. Further, irrigation allows farmers to reap the economic benefits of growing higher-value cash crops.
Even though the impact of irrigation is impressive, we haven’t done enough to optimize the efficiency of irrigated agriculture. There are several challenges preventing us from unlocking this vital outcome.
