Factors Affecting Food Security (AQA GCSE Biology)

Food Production

• Food security is having enough food to feed a population

• That ‘population’ could represent a group of people on a range of different scales, from a particular a family, to a town, to a region or even a whole country

• Food security gives an indication of how much food is available

Biological factors threatening food security table

• Sustainable methods of farming and producing food are needed in order to overcome food shortages and help populations whose food security is under threat

• Sustainable food production involves making enough food but ensuring this is done without using resources (such as water and soils) faster than these resources can be renewed and used again
