Food security Flashcards
Food security
the measure of an individual’s ability to access food that is nutritious and sufficient in quantity.
crop
plant that is harvested
Yield
an amount produced of an agricultural or industrial product per measurement
Harvesting
The process of gathering crops
How does the demand for goods affect the prices and wages
when demand is high, prices decrease, wages increase
How does climate change affect food
- disrupt food availability
- reduce access to food
- effect food quality
How does climate change affect population?
the climate becomes inhospitable to humans,
sea rising floods.
shrinking arable land.
arable land
any land capable of being ploughed and used to grow crops.
Stapel foods
Maze
rice
potatoes
soy beans
What aare stapel diets
the food or foods that a person or animal eats most often
agriculture
the practice of cultivating plants and livestock.
Green revloution
The introduction of High Yielding Varieties of seeds and the increased use of chemical fertilisers and irrigation
Changes in agriculture
the selective breeding of livestock
the removal of common property rights to land
new systems of cropping,
When was cacao grown
5,300 years ago, in equatorial South America
Why is cacoa diffciult to grow
It requires high rainfall and temperatures to grow,
Why is food secuirty in the future problematic
unequal distribution
climate change decreasing food production
expensive food
Why certain places have low food security
drought
large population
poor soil quailty
war and civil unrest
Why certain places have high food security
High availability
Equal distribution
not corrupt government
good infrastructure
How do we take food out of the ground
cutting corn, picking fruit-harvesting
Calculating yield
the amount harvested/ amount of land
How does climate chaneg affect arable land
Extreme temperatues, natural disasters, less/more rain
What stapel food is given to animals
Corn
What stapel food is given to the industry
Biofuel(plant based ‘petrol’)
Who makes rice and who eats it
Rice is grown in asia mainly in countries such as china and india and is consumed by mostly asia.
If crop yield is high
demand is low, prices are low
if crop yield is low
demand is high and prices are high
true or false; stapel foods are the dominant portion of a person’s diet
true
true or false; maize is for human and animal consumption and biofuels
true
why climate and topography impact rice production
can prevent land depredation, less erosion
why will food security beccome more of a problem in the future
-fewer arable land
-de stabilation
climate change
