Asia's farms embrace tech revolution as workers become scarce

Agricultural and fishing industries in Asia are being transformed by technology as the cheap and abundant labor that they long relied on erodes due to demographic pressures. Rising wages across other industries have created a labor shortage in the traditional staples of economies, especially in Southeast Asia. To make up for a shrinking population of farmers, companies are adopting artificial intelligence and drones to help grow food more cheaply and efficiently. In Vietnam, Minh Phu Seafood is building new vinyl shrimp tanks that are shaped like deep bowls. Water is swirled around the tank so that waste collects at the bottom where it can easily be drained.
