When the annual supply of water per person falls below 1700m3 Key definitions When the annual supply of water per person falls below 1700m3 When the annual supply of water per person falls below 1000m3 Occurs when more than 75% of a country’s or a region’s blue water flows are being used - this currently applies to around 25% of the world’s population Occurs when the development of the blue water sources is limited by a lack of capital, technology and good governance. The hidden flow of water when food or other commodities are traded Virtual water water scarcity physical scarcity economic scarcity water stress 1700m3 = water stress, 1000m3 = water scarcity, 75% water use = physical scarcity, lack of capital = economic scarcity, hidden flow = virtual water

Physical distribution Water availability gap It is suggested by the UN, that as a world there is enough water to go around, however, this simply is not the case. Physical distribution Water availability gap What three issues do you think stop there from being enough water to go around? Gap between rising demand and diminishing supplies
