Water stress - occurs when the demand for water exceeds the available amount during a certain period or when poor quality restricts its use
Poverty - more than lack of income, it includes hunger and malnutrition, limited access to education and other basic services
Common misconception
Rising demand for food is simply down to the world's growing population.
This is one reason for growing demand for food but economic development is another factor that affects demand as people become richer they eat more meat and so more grain or land to graze is needed to feed those animals.
