Global Food Flashcards
(41 cards)
define food security
having access to safe, affordable food
define food insecurity
lacking access to safe, affordable food
how does population growth increase food demand
as the population grows, there are more mouths to feed
demand increases
how does economic growth increase food demand
as the economy becomes wealthier, there is greater demand for higher quality produce and a range of ingredients
demand increases
define sustainable food
production of food that increases yield to meet the demand of future generations whilst protecting the environment
define food loss
food that is thrown away before it meets the consumer due to it’s deterioration after harvest
define food waste
food that is thrown away after meeting the consumer as it has expired or not been used
define undernourishment
not meeting the sufficient calorie intake in your diet
give 2 sustainable food practices
growing crops in your garden- local, reduces food miles
using used fruit and vegetables as compost- they decompose into nutrient-rich soil
list 5 factors that affect food availability
climate
technology
pests
conflict
poverty
how does climate affect food availability
crops require a good amount of rainfall- dry regions will produce less food
extreme weather, e.g storms, will destroy crops
global warming- causes droughts
how does technology affect food availability
HIC’s can afford advanced technology- e.g irrigation systems = higher crop yield
LIC’s cannot afford new technology = smaller crop yield
how does pests affect food availability
pests eat crops= less harvest
how does conflict affect food availability
farmers are forced to flee their farms + homes = nobody to farm crops= less food
crops are burnt during battle
how does poverty affect food availability
if people cannot afford healthcare they become sick and unable to work
less workers on farms= less food
social impacts of food insecurity
undernourishment
when crop yield decreases food prices rise
poorer people cannot afford food
they become malnourished
they cannot afford healthcare
become sick and unable to work
lose their income
economic impacts of food insecurity
if workers are undernourished and cannot work, they don’t receive incomes
less government taxes
less economic development
environmental impacts of food insecurity
overgrazing: cattle eat vegetation and leave soil exposed to leaching= soil erosion= infertile land
over-cultivation: farmers forced to farm on marginal land= leads to desertification
pesticides- pollute water supplies= harms animals
list 4 management strategies to increase food supply
aeroponics
hydroponics
impossible burger
irrigation
explain pros and cons of aeroponics
plants grow in the air
:) get more oxygen- more respiration,more energy for more growth
:) requires less water
:( expensive
:( requires advanced technology- LIC’s cannot afford
explain pros and cons of hydroponics
plants grow in water
:) get more water= more photosynthesis= more growth
:( expensive
:( requires advanced technology- LIC’s cannot afford
explain pros and cons of the impossible burger
substitute for meat- plant-based burger
:) less cattle farmed- less methane released, less global warming
:( high in saturated fats- obesity risk
explain pros and cons of irrigation systems
artificially watering crops
:) saves time
:) higher crop yield
:( locals displaced to build dams
:( farmers are replaced
why are greenhouses good for food production
humid and warm- ideal conditions for plant growth
less pesticides are used
