Depending on water availability, rice is grown in different ecologies:
| Lowland Irrigated | Lowland Rainfed | Upland / Aerobic | Deep Water |
| 55% of the global rice area, 75% of global rice production, intensive cropping systems with a grain production of 10-15 t ha-1year-1, largest areas in China (31 M ha), India (19 M ha), Indonesia (7 M ha), Vietnam (3 M ha). | Lack of water control, is grown on 36 M ha, mainly in Asia. It is the most common system in eastern India, Myanmar, Thailand, Bangladesh, Cambodia. | 10% of the global rice area, 17 M ha, mainly in India (6.2 M ha), Brazil (3.1 M ha), Indonesia (1.4 M ha). | = floating rice, inland and coastal wetland areas, depth of water is >50 cm, 12 M ha in South and Southeast Asia, 4% of the global rice production. |
