In this photo taken Oct. 4, 2012, a worker walks in a plant nursery, which is used technology called the "autopot system,"at a rural community in Pulau Manis village, Pahang state, Malaysia. Each plant is in its own pot that regulates the delivery of water and nutrients, using less water than other farming methods. Malaysian technology firm Iris Corp. built two years ago this rural community where villagers - 80 families in all - live for free in low-cost bungalows and work on a high-tech hydroponic farm, a setup the company hopes to replicate elsewhere.
