- Water stress occurs when the demand for water exceeds the amount available during a certain period - less than 1000 m3 per capita per year
- Water scarcity is the lack of sufficient water to meet the demand of a region
- Physical: when shortages occur because demand exceeds supply
- Economic: exists when people simply cannot afford water, even if its available
