Agriculture
crops y'all, go farming
Notes
Types of farming
Livestock and poultry; meat. dairy, and eggs utilizes rangeland
Agriculture: growing on crop (mono culture) or many crops (poly culture)
Aquaculture: raising aquatic organisms for food
when food isnt avalible
malnutrition: a condition caused by not consuming enough necessary nutrients
famine: a food scarcity so widespread that it causes severe malnutrition throughout large geographic areas
people go hungry because
crop failure due to
drought,soil detereration, disease
population size> crop yield
when food is overabundant
over nutrition: food energy intake exceeds energy use and causes excess body fat
similar health problems to those who are underfer
lower life expectancy
greater susceptibility to disease and illness
lower productivity and life quality
past farming
the first agricultural revolution began as earlt as 9000 BC
nomads-> settlements
cross pollination first began
grew enough to support family trade
green revolution
goals:
stop hunger
increase crop yeild
minimize crop losses/ failure
methods:
new, high-yield grain varieties
pesticides
fertilizers
better management practice
more technologically advanced machinery
how its changed
vision: treat agriculture as a business (agribusiness) plant a large amount to of single species (mono cropping)
Drawbacks
too expensive
air, soil, and water pollution due to toxic chemicals
uneven distribution- poorer countries still can't transport food
practices of conventional farming
maximize output- high efficiency
minimize space
concentrated animal feeding operations (CAFOS)
genetically modified crops (temp and chemical resistance)
heavy equipment (fossil fuels)
chemicals (pesticides and fertilizers)
sustainable farming practices
sustainable output
takes more space
pasture/ rangeland feeding
incorporates more human and animal labor
minimize chemical usage (biochemicals)
poly-culture
Benefits
conventional
lower food costs
fast production times (more growing seasons in a given year
meets increase demands
sustainable
Healthier for humans and organisms alike
Higher quality foods (in terms of energy)
Conserves energy and water resources
Lower biodiversity/environmental impact
Risks/ impact
conventional
Biodiversity/Habitat Degradation
Soil, Water, and Air Pollution
Erosion/Desertification
Energy and Water Loss
Contamination of Human Foods
Pesticide and Antibiotic Resistance
sustainable
Higher food costs
Low yield
Decreased availability
More susceptible to storms, pests, changes in environment, etc.
