1. WATER SCARCITY

2. 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.

3. The UN states by 2025, 1.8 billion people will be living in countries or regions with absolute water scarcity, Two-thirds of the world population could be under stress conditions

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

5. 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.

6. 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.
