Question
Define food security.
Answer
When **all people, at all times, have reliable access** to enough safe, nutritious food.
Question
Food availability vs access?
Answer
**Availability** = is there enough food in the area; **access** = can people reach and afford it.
Question
Why can a country grow lots of food yet be food-insecure?
Answer
If the poor **cannot afford** it, access fails even when food is available.
Question
Name four factors that lower food security.
Answer
**Drought/climate, conflict, poverty/high prices, rapid population growth** (also land degradation, pests).
Question
How does drought threaten food security?
Answer
Failed rains and heat **ruin harvests**, so less food is produced and people go hungry.
Question
How does conflict threaten food security?
Answer
War **destroys farms and blocks supply routes**, so food cannot reach people.
Question
How does a growing middle class change diets?
Answer
Higher incomes mean **more meat, dairy and variety** and more food eaten overall.
Question
Why does richer eating add land-use pressure?
Answer
**Meat and dairy need far more land and feed-grain**, so land is cleared to graze animals and grow feed.
Question
Give one way development could **raise** food available.
Answer
Better technology, irrigation and infrastructure let a country **grow and import more food**.
Question
How can a warmer climate affect food security?
Answer
It can **lower** it (drought, failed harvests) but also **raise** it where new areas become warm enough to farm.
Question
Describe vs Explain on a food-emergency map?
Answer
**Describe** = state where the zones are; **Explain** = give the reason behind the pattern.
