What is food security?

Food security means having enough safe, nutritious food available for all people to live healthy lives.

How can a rising human population reduce food security?

More people need food, so demand rises faster than the amount of food that can be produced.

How can changing diets in some countries affect global food security?

As people eat more meat and fish, more crops are used to feed animals, so less food is directly available for people.

How does overfishing affect food security?

Catching too many fish lowers fish stocks, so there are fewer fish to eat now and in the future.

How can new pests and pathogens reduce food security?

They can damage crops and farm animals, leading to lower food yields and food shortages.

How can climate change and extreme weather affect food security?

Droughts, floods or heatwaves can kill crops and animals, so less food is produced.

How can using farmland to grow biofuels instead of food affect food security?

Land used for biofuel crops cannot grow food crops, so the total amount of food produced goes down.

How can the high cost of fertilisers, seeds and machinery affect food security?

Farmers may not afford these, so they grow less food and crop yields stay low.

How can wars and conflicts affect food security?

Fighting can destroy fields and roads, and can stop food aid, so people cannot get enough food.

How can poor transport and storage systems affect food security?

Without good roads and cold storage, much food is wasted or spoils before it reaches shops.

Why is sustainable farming important for long-term food security?

It protects soil, water and ecosystems, so land can keep producing enough food in the future.

How can poverty and unequal food distribution affect food security?

Some people cannot afford to buy food, even if there is enough food in a country, so they stay hungry.
