Collectable water from rainfall.

The water that falls on roofs and hard surfaces usually flowing into rivers and the sea and recharging the ground water.

In nature the global average proportion of total rainfall that is blue water is about 40%.

1.1 Blue water

About 4,000 to 5,000 km3 are annually withdrawn from blue water sources

On average, the rate of withdrawal of blue water has been about two and a half times faster than the rate of population increase during this century.

About 70 % of the total is supplied for irrigation purposes

Facts about Blue water

1.2 Grey water

Water from our bathroom, showers, washing machine, etc.

It`s not from the toilet

It is a safe and even benefical source of irrigation water in a yard

Water transferred back to the atmosphere from soils, natural foliage and rain-fed agriculture.

The United Nations Water Program

Climate change is significantly affecting the availability of freshwater in many regions around the world.

1.3 Green Water

Pollution that affects our rivers, lochs and wetlands is often characterised in two different forms.

Point source pollutionDiffuse source pollution

Point source pollution can come from sewage treatment works, factories and input from fish farms.

The impacts of pollution can be a loss of biodiversity, as well as adverse effects to our own health.

2.1 Water pollution in Scotland

Quality of water: 57th place in the world - measured lakes and rivers - polluted due to farming and industry

Germany’s freshwater is one of the best in the world- drinking water is one of the cleanest all over the world.

2.2 Water pollution in Germany

All Chinese rivers are polluted to some degree:

Household water

Industrial water

Agricultural Water

2.3 Water pollution in China

Condition of water bodiesIn the last decade the population has decreased 8% and
