Factors affecting food securitySpec 4.7.5.1
- Food security
- Having enough food to feed a population.
Biological factors which are threatening food security include:
- the increasing birth rate has threatened food security in some countries
- changing diets in developed countries means scarce food resources are transported around the world
- new pests and pathogens that affect farming
- environmental changes that affect food production, such as widespread famine occurring in some countries if rains fail
- the cost of agricultural inputs
- conflicts that have arisen in some parts of the world which affect the availability of water or food.
Sustainable methods must be found to feed all people on Earth.
