Water Stress = Less than 1700 m3 per person per year Water Scarcity = Less than 1000 m3 per person per year 1.5 billion people lack access to safe drinking water supplies (World Bank) 2.5 billion people lack access to basic sanitation (World Bank) Malarial and diarrheic diseases are leading causes of infant mortality
