- this typically occurs in LICs who lack reliable salination infrastructure
- e.g Continental & SE Asia
9
Q
Give some possible causes of water scarcity
A
- lack of annual or seasonal precipitation
- lack of investment & managemnt of water infrastructure to meet demand
- scarcity may also be a social construct duet to wealth, expectation or unusual behaviour
10
Q
Why is water supplies not equitablly distributed
A
- although access to safe, potable water is a human right, it is treated as a commodity to be paid for

22
Q
Supply vs Demand
what leads to a rise in cost of water
