It's an exciting time to be a microbiologist working in rice research. A global push towards the cultivation of water-saving rice is enabling farmers to harness the power of microbes that thrive in less water.

Some farmers already use rice production systems that reduce or eliminate the length of time rice is submerged in a flooded paddy field. At the sowing stage, planting of pre-germinated seeds (direct seeding) rather than traditional transplanting of small plants into flooded paddies reduces the need for waterlogged fields. Waterlogged rice paddies emit huge amounts of methane, a potent greenhouse gas.

Similarly, an irrigation practice known as alternate wetting and drying uses pipes drilled into fields to encourage water management and intermittent flooding, reducing water usage and methane emissions.
