The 20 questions

  1. What is water security?

    • When people can reliably get enough safe, clean water for their needs
    • When water is stored in tall towers in cities across the country
    • When a country has the most rivers in the world, flowing across its land and into every sea
    • When rain falls every single day of the year in the same place

  2. What is water stress?

    • When a river is very wide and deep, with fast currents that carry boats and sand through the town every day
    • When water is too hot to drink in the summer months
    • When a lake freezes over in winter, covered in thick ice
    • When demand for water is greater than the safe supply available

  3. What is water scarcity?

    • When there is simply not enough water to meet everyone's needs
    • When water is too salty to use for farming, even in the wet season
    • When rain falls too heavily in one day across the whole town
    • When a city has too many taps and too many pipes

  4. What is contamination of water?

    • When water is moved by pipes to another town along the road
    • When water is heated to make it boil in a large kettle for cooking and cleaning in the home
    • When water is made dirty or unsafe by waste, sewage or chemicals
    • When water falls as snow on a mountain and melts in spring

  5. About how many litres of water per person per day does a UK home use?

    • About 14 litres
    • About 140 litres
    • About 14,000 litres
    • About 1,400 litres

  6. Roughly how many litres per person per day may a water-stressed area have?

    • About 100 litres
    • About 140 litres
    • Over 500 litres
    • Under 20 litres

  7. Which example shows a 'too little' water problem?

    • A long drought that dries up wells
    • Factory chemicals leaking into a river from a pipe
    • Sewage flowing into the water supply from a broken pipe
    • A monsoon flood swamping a city in the rainy season

  8. Which example shows a 'too much' water problem?

    • A monsoon flood that swamps a city
    • Wells that dry up in summer across the farms
    • Factory chemicals in a river from a leaking tank
    • A reservoir running dangerously low in the dry season

  9. Which example shows a 'too dirty' water problem?

    • A long drought with empty wells in the villages
    • Floods that cover farmland with water for many weeks
    • Sewage flowing into the water supply
    • A reservoir that is nearly empty after a dry spell

  10. On a water-stress map, what does darker shading usually show?

    • Lower water stress
    • No data for that country
    • Higher water stress
    • Larger rivers on the map

  11. Which region is usually shaded darkest on a global water-stress map?

    • Scandinavia
    • The Middle East and North Africa
    • The Congo Basin
    • Northern Europe, with its many lakes and rivers and frequent rain

  12. Which region is usually shaded lightest, showing low water stress?

    • Northern Europe
    • North Africa
    • The Sahel
    • The Middle East

  13. Which of these situations shows water security?

    • Villagers carry water by hand over long distances each day
    • A growing city's demand is greater than its safe supply
    • Families queue for hours at one shared well
    • Clean tap water is always available at home

  14. Why does water stress occur in a fast-growing city?

    • Demand rises faster than the safe supply can meet it
    • Its tap water is always free for every household
    • The city has too many rivers flowing through the centre
    • Its rain falls too evenly through the year across the valley

  15. Would Saudi Arabia be shaded dark or light on a water-stress map, and why?

    • Dark, because it is hot and dry with little rainfall
    • Light, because it is near the sea and gets sea breezes
    • Light, because it has many rivers that run through the land
    • White, because it has no rain at all in any year

  16. Why can a country be water-stressed even where it rains?

    • Rain never falls in water-stressed countries across the region
    • Water stress only happens in deserts with no rain at all
    • Rain always supplies enough water for every need of the people
    • Demand may exceed the safe supply, so stress can still occur

  17. How can flooding also make water dirty?

    • Floods never affect water supplies, which are kept in tanks
    • Floodwater can spread sewage and contaminate clean water
    • Floods make water too cold to drink, so people stop drinking it
    • Floodwater removes all bacteria from taps in the homes

  18. Why is cholera a concern where water is unsafe?

    • It only spreads through the air, not through water supplies
    • It is caused by drinking clean rainwater from the roof
    • It spreads through contaminated water and can be deadly
    • It only affects plants growing in the fields near rivers

  19. Which judgement best explains why water security is a growing global challenge?

    • Water problems have been solved everywhere in the world today
    • Water is becoming more plentiful as populations shrink, so there is now no need for dams or pipes anywhere
    • Water security only affects wealthy countries that have dams
    • Rising population and climate pressures increase demand while droughts, floods and pollution reduce safe supply

  20. Why does the 'too much, too little, too dirty' framework show that water security has several threats?

    • Each problem threatens safe supply in a different way, so one fix cannot solve all three
    • Only the 'too dirty' problem matters for health in the modern world
    • Water security depends on a single river only in every country
    • All three problems have the same cause and fix in every place, so one fix will always solve them all
