subsistence agriculture found in LDCs, is the production of food primarily for consumption by the farmer family
commercial agriculture found in MDCs, is the production of food primarily for sale off the farm (ex: dairy famrs, ranching)
prime agricultural land most productive land
agribusiness commercial agriculture characterized by the integration of different steps in the food-processing industry, usually thorugh ownership by large corporation (ex: general mills, the meat industry)
shifting cultivation a form of subsistence agriculture in which people shift activity from one field to another; each field is used for crops for relatively a few years and left fallow for a relatively long period (ex: upland rice in Southeast Asia)
slash-and-burn agriculture another name for shifting cultivation because fields are cleared by slashing the vegetation and burnng the debris
swidden patch of clear land for planting through slashing and burning
pastoral nomadism a form of subsistence agriculture based on herding domesticated aniamls (ex: camels, goats, sheeps)
transhumance is a seasonal migration of livestock between moutains and lowland pasture areas
intensive subsistence agriculture 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 (ex: wet rice and wheat)
wet rice practice of planting rice on dry land in a nursery and then moving the seedlings to a flooded field to promote growth
sawah flooded field for growing rice
paddy malay word for rice, commonly used for Sawah
chaff husks of grain separated from the seed threshing

double cropping harvesting twice a year from the same field

ride tillage 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 (ex: miracle wheat seed)
