double cropping
planting two crops one after another on a single plot in a year
triple cropping
planting three crops in the same year
(EX

irrigation
opens up more land to cultivation than would normally be possible in arid climates and is responsible for close to three-quarters of world freshwater use and up to 90 percent of freshwater use in the most poverty-stricken countries of the world
aquifers
underground water tables that gives water to irrigation farms
conservation
the practice of preserving and carefully managing the environment and its natural resources
conservation agriculture
an increasingly important way of providing a sustainable farming system without sacrificing crop production
no-tillage
involves not plowing the soil so that soil erosion is greatly reduced and soil fertility is increased by retaining natural vegetation
inter-planting
planting fast-growing crops alongside slow-growing crops, allowing a farmer to harvest the fast-growing crop before the slow-growing crop shades it out
sustainable yield
the amount of crops or animals that can be raised without endangering local resources such as soil, irrigation, or groundwater, or what can be raised without too many expensive inputs that would make farming unprofitable
(EX
corn has been used to make ethanol, an alcohol that can supplement gasoline and make it burn cleaner)
slash and burn agriculture
occurred in tropical rainforest regions with farmers shifting from one plot of land to another every few years as soil nutrients become depleted
extensive pastoralism
the shifting of animal herds between grazing pastures, has remained popular in several arid parts of the world, especially Africa, the Middle East, and Central Asia, where dry grassland is the common landcover
desertification
any human process that turns a vegetated environment into a desert-like landscape
soil salination
the evaporation of water that can trap mineral salts on the surface soil layer
EX
dietary restrictions can limit the trade of beef (to India) or pork (to Islamic societies)
EX
countries with larger governmental safety nets tend to support farmers in a more socialistic manner
EX
irrigation becomes necessary in water-scarce regions
vegetative planting
where the shoots, stems, and roots of existing wild plants were collected and grown together
seed agriculture
where the fertilized seed grains and fruits of plants were collected and replanted together
horticulture
where plant varieties that thrived in different soil or climate conditions were cultivated
hearths of domestication
the areas where most of this early agricultural activity originated
the Columbian exchange
domesticated New World crops that made their way to the rest of the world through relocation diffusion
(EX
maize, from the new world, and wheat, from the old world, were exchanged)
