factors affecting food security
physical factors
temperature
too cold or hot
crops will not grow if temperature is too hot or cold
disease
crops can be destroyed by insects, parasites
water
a suitable supply of water is needed to grow food
soil
growing food and the type of crops that can be grown , depends on the quality of soil
Human factors
distribution
Food must be distributed to those who need it. Poor transport
infrastructure makes it difficult to get food to where it is needed.
poverty
People suffer from food insecurity when they cannot afford to buy food. Farmers may not be able to afford seeds or tools.
war and conflict
Conflicts disrupt farming and make distributing food more difficult. War can force millions to flee from their homes to places where there is not enough food, leading to food
Land ownership:
Farmers often do not own the land they farm. Land might be bought by TNCs and used to grow export crops, so there is less land for growing food for local people.
Waste:
Lots of food is wasted. For example, in Vietnam, as much as 25% of rice goes to waste because of poor transport, storage and processing. In the UK, 4.4 million apples are thrown away every day.
