- - - - Physical and economic access to food. Needs to be enough food available it must be in reach of those who need it. Enough food to meet the needs of every person on earth.
    - - Using food safely, applying knowledge about nutrition, clean water and sanitation when preparing food
    - - Food of appropriate quality available on a constant basis
  - - - The introduction of non-native plants, animals or insects into an area can have devastating effects on the natural environment. This, in turn, can develop into a situation where food security is put at risk.
    - - In many places around the world, agriculture is being threatened by competition for land. Food security may come under threat by people or corporations who want to use land for purposes other than growing food crops.
    - - The term climate change refers to long-term changes in weather events and patterns worldwide. The effects of climate change include rising global temperatures and changes in levels of rainfall.
    - - One of the biggest emerging threats to food security in recent years has come from the growth in the amount of land being used to produce crops used to feed cars, not people
    - - Water scarcity is the lack of access to enough safe water. The supply of clean, safe water is important not only for people to drink, but for the safe growing of crops for food.
    - - Armed conflict is another complex and severe threat to food security. Armed conflicts have the potential to affect the food security of entire regions and may even result in famine.
