Water scarcity occurs when the demand for water exceeds the available supply during a certain period or when poor water quality restricts its use. Physical scarcity is caused by limited access to water in areas where demand outstrips the land's ability to provide water, like dry or arid regions. Economic scarcity is when a population lacks the monetary means to access an adequate water source due to unequal distribution of resources often caused by political or ethnic conflicts. Supply issues that can exacerbate scarcity include water sources being inaccessible or out of reach, lack of infrastructure, loss of water from rain and evaporation, depletion of fossilized aquifers and wetlands, and pollution.

3. Water stress and Water scarcity
occur when the demand for water exceeds the available
amount during a certain period or when poor quality
restricts its use.

5. "water stress" is when annual
water supplies drop below
1,700 cubic meters per person
per year, according to the
Falkenmark Water Stress
Indicator

6. PHYSICAL SCARCITY
Physical access to water is
limited. It is when the
demand outstrips the lands
ability to provide the needed
water. For the most part,
dry parts of the world or
arid regions are most often
associated with physical
scarcity.

7. ECONOMIC SCARCITY
• When a population does not
have the necessary monetary
means to utilize an adequate
source of water. It is about a
unequal distribution of
resources for many reasons,
including political and ethnic
conflict.
