What is water security?

- Having a reliable and sustainable source of enough good quality water to meet everyone's needs (industry, agriculture and personal health).

1 of 9

What does water security depend on?

- Amount of water available (e.g. from rainfall, rivers, groundwater etc.). - No. of people who need to use the water. - Accessibility to the water (can be hard if you're poor).

2 of 9

What is water surplus?

- Having more water than is needed.

3 of 9

What is water deficit?

- When there's not enough water to meet people's needs.

4 of 9

What is water insecurity?

- Water deficit can lead to water insecurity. - Water insecurity is when there's not enough clean water to keep everyone healthy, or enable them to make a living (e.g. to water crops, provide energy etc.).

5 of 9

What is water stress?

- When demand for water exceeds supply during a certain period, or when water is not of high enough quality to use.

6 of 9

Global patterns of water surplus and deficit

- Water security will occur in areas with high rainfall and/or very low pop. density (e.g. Canada, Brazil). - Water insecurity will occur in areas with low rainfall and/or high pop. density (e.g. Libya, Mexico).

7 of 9

Why is water consumption rising? - rising pop.

- Global pop. is increasing (each person needs water for drinking, washing, preparing food, etc.). - More people = more food needs to be grown-irrigation for agriculture uses 70% if world's freshwater resources.

8 of 9

Why is water consumption rising? - economic development

-World becoming increasingly developed.-Industralisation (more developed=produces more goods=water used for manufacturing).-Energy production (e.g. water used in cooling thermal power plants).-Wealthier=rising living standards=more toilets etc..
