Food Security
This exists when people have reliable access to sufficient, safe, and nutritious food to live healthy and active lives.
Food Security
This threat occurs when a lack of rain causes crops to dry out and reduces food production.
Drought
This is the practice of growing only one type of crop on a piece of land (e.g., only growing apples).
Monoculture
This method slows water run-off and reduces soil erosion by ploughing along the natural curves of the land.
Contour Ploughing
What is the difference between "Exploitation" and "Over-exploitation"?
Exploitation is using resources for our own benefit, while over-exploitation is using them too much or too quickly
There are three elements of food security. One is "Food Availability." Name ONE of the other two.
Food Access
OR
Food Utilisation
Heavy rain and this weather event can destroy crops, livestock, and farm land.
Floods
This method involves growing different crops in a sequence on the same land to maintain soil fertility and reduce pests.
Crop Rotation
What does "Appropriate Technology" refer to in farming?
affordable machines and practical methods that improve farming and protect the environment
What happens to a renewable resource if it is used wastefully and doesn't have enough time to be replaced?
It may not have enough time to be replaced (leading to depletion)
This element of food security means that people must be able to afford the food that is available.
Food Access
Insects and diseases fall under this main threat to food security, as they damage crops and kill livestock.
Pest & Disease
This method involves covering the soil with material to retain moisture in plants and protect against soil erosion.
Mulching
How does Mulching directly help a farmer during a dry season?
It retains moisture in the plants/soil
How does population growth directly threaten food security?
It puts more pressure on land, water, and other resources used to produce food
The main cause for an increase in the demand for food globally is this.
Population Growth
If a farmer experiences a drought followed by a flood, what happens to the food security of the local community?
Food security decreases because food production is reduced and farm land is destroyed
This type of farming means producing food using methods that protect the environment and conserve natural resources for future farming.
Sustainable Farming
How does Crop Rotation help a farmer deal with pests?
It reduces pest and disease spread by changing the host crops
If a renewable resource is managed well, what happens to it?
It can be used repeatedly
Explain what "Food Utilisation" means as an element of food security.
People must be able to use food effectively through a nutritious diet and safe food
Name the THREE main threats to food security discussed in your notes.
Droughts, Floods, and Pest & Disease.
Give TWO disadvantages of Monoculture mentioned in your notes.
Soil nutrients become depleted
OR
Pest & disease spread easily
OR
Biodiversity decreases?
If a farmer uses "Appropriate Technology," why is it better for the environment than using massive, expensive, heavy machinery?
It uses practical methods that protect the environment (and is affordable)
Explain how a drought can lead to a loss of jobs for a rural farming community.
Drought causes crops to dry out, reducing food production, which means farmers cannot afford to pay workers
