Question
What is food security?
Answer
When all people can always get enough safe, nutritious food to live healthy lives — with four parts: availability, access, use and stability.
Question
What are the four parts of food security?
Answer
Availability (enough produced/imported), access (can people afford and reach it), use (safe and nutritious), and stability (reliable supply).
Question
What does 'access' mean in food security?
Answer
Whether people can actually obtain food — can they afford it and reach it; this is where most hunger comes from.
Question
Why does food security matter for development?
Answer
Well-fed children learn better and become healthier, more productive adults; food security underpins health, education and stability.
Question
What causes food insecurity?
Answer
Poverty, conflict, climate shocks, volatile global prices, weak infrastructure, and waste and unfair markets.
Question
Why is hunger often about access, not supply?
Answer
The world grows enough food, so most hunger happens because poor people cannot afford or reach it, or conflict and markets block it.
Question
Why are modern famines usually failures of access?
Answer
Because they happen when people cannot obtain food — conflict blocks supply, prices spike, or local harvests fail while imports are unaffordable — not a simple global shortage.
Question
What is the self-sufficiency vs trade debate in food?
Answer
Growing your own food protects against price spikes and supply cuts; trade lets countries import cheaply but is vulnerable to crises — most food security needs a balance.
Question
How does food insecurity harm development?
Answer
Hunger stunts children, weakens workers and fuels instability, trapping poor countries in a cycle that holds back development.
Question
How can technology help food security?
Answer
New seeds, irrigation and farming methods can raise yields, but they help most when combined with access — affordability and distribution.
Question
What is a balanced view of the causes of hunger?
Answer
Access (poverty, conflict, prices, distribution) is usually the deeper cause, but production and climate also matter, so both must be tackled.
