subsistence -> agrobusiness, family -> corporations, increase in size of average farm, decrease in number of farmers, increase in mechanization, crop dusters -> safer spread of pesticide, improved refrigeration -> greater distribution distance, increase in crop yield, increase in grazing
Share of Land
shared area of land that is available land that can be used to grow stuff
Green Revolution
US state department program, bring agricultural tech to other countries, increase in food production leads to political stability, high yield varieties of cereal, chemical fertilizers and pesticides, soil treatments, controlled water supply, increase in mechanization
