the planting of more than one crop on the same plot of land
double cropping
planting two crops one after another on a single plot in a year

planting three crops in the same year
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
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
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
Green Revolution
occurred in the 1950s and 1960s when tropical plant and animal hybrids and chemical fertilizers and pesticides began to be used in Third-World agriculture
primary economic activity
farmers now produce one or more crops
secondary economic activity
process the crop
tertiary economic activity
advertise and market it through afarmers co-op or other market
Recombinant Bovine Growth Hormone, or rBGH
a synthetic hormone widely used in both the production of beef and milk in the United States and some other countries
downer cattle
beef cows that appear ill or are lame and cannot be used for human consumption, but can wind up in pet food or animal feed instead
organic
crops and animals must not be grown using genetic engineering, must be free of pesticides, antibiotics, and synthetic hormones, must not use artificial fertilizers, and must feed on completely organic crops
grass-fed cattle have also brought significantly higher prices to gourmet consumers who seek the more natural-tasting beef, as corn
and soy-based cattle feed has been blamed for less flavorful beef
fair trade movement

the region around a city to which fresh milk is delivered without spoiling In terms of travel time and distance
ultra-high temperature (UHT) pasteurization
a new milk preservation method where milk is flash-pasteurized at very high temperatures and under pressure to keep the water in it from turning to steam and then stored in a sterile box container that is sealed in plastic to prevent contamination
commodity chains
