| Agribusiness | System of commercial farming found in the United States and other relatively developed countries |
| Prime agricultural land | The most productive farmland |
| Shifting cultivation | A form of subsistence agriculture in which people shift activity from one field to another; each field is used for crops for a relatively few years and left fallow for a relatively long period |

| Pastoral Nomadism | A form of subsistence agriculture based on the herding of domesticated animals |
| Transhumance | seasonal migration of livestock between mountains and lowland pasture areas |
| Intensive subsistence agriculture | A form of subsistence agriculture in which farmers must expend a relatively large amount of effort to produce the maximum feasible yield from a parcel of land |
| Wet rice | The practice of planting rice on dry land in a nursery and then moving the seedlings to a flooded field to promote growth |
| Paddy | Malay word for wet rice, commonly used instead of Sawah |
| Sawah | Flooded field for growing rice |

| Ridge tillage | A system of planting crops on ridge tops, in order to reduce farm production costs and promote greater soil conservation |
| Desertification | Degradation of land, especially in semiarid areas, primarily because of human actions like excessive crop planting, animal grazing, and tree cutting |
| Green revolution | Rapid diffusion of new agricultural technology, especially new high-yield seeds and fertilizers |
