Food Security Basics
What does "Food Security" Mean
Having reliable access to enough safe, nutritious food to live a healthy life.
What does “landscape alteration” mean?
Changing the natural environment, such as clearing land, building roads, or modifying waterways.
What are farm inputs?
Things farmers use to grow crops, like seeds, fertiliser, water, and tools.
What are supply and demand?
Supply is how much food is available; demand is how much people want to buy.
What is an environmental consequence?
A result or impact on the environment caused by human actions or natural events.
How is food insecurity different from food security?
Food insecurity means people don’t have reliable access to enough safe, nutritious food.
How can deforestation affect farming?
Removing trees can increase erosion and reduce soil quality, making farming harder.
How can new machinery help farmers?
It makes planting, harvesting, and managing crops faster and more efficient.
How does high demand affect food prices?
Prices usually rise when more people want the same amount of food.
How can pollution affect food production?
Polluted soil or water harms crops and reduces yields.
Why is access to food just as important as having food available?
Food might exist in a country, but people need money, transport, and physical access to actually get it.
How does irrigation change a landscape?
Irrigation adds artificial water channels that reshape land and allow crops to grow in dry areas.
How do fertilisers and pesticides upgrade farm inputs?
Fertilisers boost nutrients; pesticides protect crops from insects and disease.
How does crop failure change food supply?
It reduces the amount of food available, often causing shortages.
How does soil erosion affect farming?
It removes fertile topsoil, making it harder for crops to grow.
How can population growth put pressure on food security?
More people means higher demand for food, which can strain farming, water supplies, and distribution.
How can urban expansion reduce food production?
Cities spread into rural areas, replacing farmland with housing and roads.
How does digital technology (like sensors or drones) improve farming?
It gives farmers accurate data to manage water, soil, and crop health more precisely.
How can global events (like pandemics or wars) affect food supply?
They disrupt transport, trade, and production, reducing how much food reaches markets.
How does climate change create environmental consequences for food systems?
It causes extreme weather, changes rainfall, and increases heat stress on crops.
Explain how conflict can create long‑term food insecurity for communities.
Conflict destroys farms, blocks food transport, forces people to flee, and can damage food systems for years.
Explain how large‑scale landscape changes (like mining or dam building) can affect food security.
They can remove farmland, change water flow, and disrupt ecosystems that support food production.
Explain how advanced technology can increase global food security.
It increases yields, reduces waste, improves water use, and helps farmers adapt to climate change.
Explain how sudden supply or demand shocks can create food insecurity.
Rapid changes can make food too expensive or unavailable, leaving people unable to access enough food.
Explain how long‑term environmental damage can reduce food security.
Damaged ecosystems produce less food, reduce biodiversity, and make farming less reliable over time.
