The project established a demonstration area in Guilin, China, to test climate-smart water technologies against traditional flooding irrigation. By implementing a "thin, shallow, wet, and dry" irrigation mode supported by intelligent monitoring and control devices, the project reduced irrigation water quotas from 390mm/mu to 351mm/mu while increasing late rice yields from 418kg/mu to 437kg/mu. Key technologies deployed include intelligent water level gauges, soil moisture monitors, and integrated gates for measurement and control to enable precise water resource management under climate change.
