Food Security Flashcards

1️⃣ Familiarise yourself with the flashcards:

  • Look through all the flashcards to see what's on both sides.
  • Make sure you understand the information on each card. If something's unclear, click the link to the revision notes at the bottom of the page for more details.

  • Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

  • Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
  • Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It's useful to remember specific examples to understand these concepts better.

What is meant by food security?

Having enough safe, nutritious food for all people to live healthy lives, now and in the future.

Name two reasons why world food demand is rising.

The human population is growing and more people want varied diets, often with more meat and processed foods.

How can rapid population growth threaten food security?

More people need food, so demand can grow faster than food production.

How can changing diets in rich countries affect food security in poorer countries?

Rich countries may import more meat and animal feed, leaving less land and grain for people in poorer countries.

Give two ways climate change can reduce crop yields.

It can cause more droughts and more floods, which can kill crops or stop them growing well.

How do new pests or pathogens affect food security?

They can spread into new areas and destroy crops or livestock, so less food is produced.

What is meant by sustainable food production?

Producing enough food now without damaging the environment or reducing the ability to produce food in the future.

Why is eating more plant-based foods usually better for food security than eating a lot of meat?

Less energy is lost between trophic levels, so more of the crop energy feeds people instead of farm animals.

How can overfishing damage future food security?

If too many fish are caught, fish stocks fall and may not recover, so there will be fewer fish to eat in the future.

Give one way people can help improve food security at home.

They can cut food waste, for example by planning meals and using leftovers instead of throwing food away.

How can the cost of fertilisers, pesticides and machinery affect food security for small farmers?

If they cannot afford these, their yields may stay low or fall, so there is less food to sell and eat.
