(Water)
- Global Demand
for Water
- Water Security
- Having a reliable and sustainable
source of enough good quality water
to meet everyone's needs. Depends on
the amount of water available.

- Water Insecurity
- Not having enough clean water
for everyone to make a living or
keep everyone healthy.

- Water Surplus
- Having more water than is needed

- When demand for
water is higher than
the supply during a
certain period of time.

Factors
- Climate
- Most places rely on rainfall. If
it's hot lots of water is also lost
from lakes/rivers (evaporation).

- Geology
- When rain falls on permeable
rock, it can't soak in, so flows
off into rivers/lakes

- Economic &
Social Factors
- Pollution of Water Sources
- Reduces the amount of clean
water. A major problem in
rapidly industrialising countries.

- Limited Infrastrucutre
- Rapid urbanisation means that the
water pipes and sewers can't be a built
quickly enough to supply the population.

- Water
Transfer
- Large-scale engineering
projects that move water
from a river that has
surplus water to a river
that has a water shortage.
Usually transferred in
canals and pipes and has
the potential to reduce
water insecurity.

- Dams &
Reservoirs
- Building a dam across a river
traps a large amount of water,
creating a reservoir. The
reservoir will be filled and the
water is released when there's a
water deficit (insecurity). It is a
consistent flow all year round.

- Water
Transfer
- Desalination
- The removal of salt from seawater so
that it can be used. Two main processes
that are used - either the seawater can
be heated to evaporate it and then
condensed to collect the freshwater or the
seawater can be passed through a special
membrane to remove the salt. It is
expensive because energy is needed to
heat the water or to force it through the
membrane. Most plants are also powered
by fossil fuels.

- Sustainable Water Supply
- Water conservation
- Trying to use less water by: buying
efficient washing machines and
dishwashers, fitting homes and
businesses with water meters,
taking shorter showers and more.

- Groundwater Management
- The amount of water being extracted
can be monitored to ensure it isn't
extracted faster than it is naturally
replaced. To prevent pollution, farmers
can be encouraged to use less artificial
fertiliser and pesticides to farmland.

- Recycling
- Taking water that has already been used and use
it again, because less water needs to be extracted
from rivers. Water from homes and industries
can be piped to water treatment plants where it
is treated to make it safe enough to reuse.
