1. LO: To understand why water is a major worldwide issue
What are the major issues that face the world with regards to water?

2. The Millennium Development goals
Improving water and sanitation underpinned many of the goals.
Final assessment was made in Did they achieve the goal?
No - 15% of the world’s people still do not have reliable access to safe water and around 35% still lacked clean sanitation.

3. 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

4. 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
