WATER FOOTPRINT

We spend most of the water food, we spend 1325 cubic metres per day, it is made up of the food and drinks we take every day. We spend 408 cubic m per day in domestic, it is implies chores in which you need water. We spend 304 cubic m per day in industrial, it is made of outdoor things. In total we spend 2037 cubic m per day.

Blue water

Fresh surface and groundwater, in other words, the water in freshwater lakes, rivers and aquifers.

Blue water availability

Natural run-off (through groundwater and rivers) minus environmental flow requirements. Blue water availability typically varies within the year and also from year to year.

Blue water footprint

Volume of surface and groundwater consumed as a result of the production of a good or service. Consumption refers to the volume of freshwater used and then evaporated or incorporated into a product. It also includes water abstracted from surface or groundwater in a catchment and returned to another catchment or the sea. It is the amount of water abstracted from groundwater or surface water that does not return to the catchment from which it was withdrawn.

Green water

The precipitation on land that does not run off or recharge the groundwater but is stored in the soil or temporarily stays on top of the soil or vegetation. Eventually, this part of precipitation evaporates or transpires through plants. Green water can be made productive for crop growth (although not all green water can be taken up by crops, because there will always be evaporation from the soil and because not all periods of the year or areas are suitable for crop growth).

Green water availability

The evapotranspiration of rainwater from land minus evapotranspiration from land reserved for natural vegetation and minus evapotranspiration from land that cannot be made productive.

Green water footprint

Volume of rainwater consumed during the production process. This is particularly relevant for agricultural and forestry products (products based on crops or wood), where it refers to the total rainwater evapotranspiration (from fields and plantations) plus the water incorporated into the harvested crop or wood.

Grey water footprint

The grey water footprint of a product is an indicator of freshwater pollution that can be associated with the production of a product over its full supply chain. It is defined as the volume of freshwater that is required to assimilate the load of pollutants based on natural background concentrations and existing ambient water quality standards. It is calculated as the volume of water that is required to dilute pollutants to such an extent that the quality of the water remains above agreed water quality standards.

WATER CULTURE AND ART

Name	El baño del caballo
Author	Joaquín Sorolla
Year	1909
Technique	Oil on canvas

In this picture we can see a white horse next to a man walking. Both are heading to the sand.

The man is naked, and represents the contact with nature .

From our point of view, this picture represents how important water is in life, we think water is important because without water life wouldn’t exist, animals like the horse or the humans couldn’t live. Water is part of our lives, so we must care for it.

What about us?

We are a team of students at the Maria Inmaculada school, of 3rd of E.S.O.

We are four girls and two boys ready to work.

We have been working at the laboratory since we start this year. And we are so excited because we can share all we have studied.

See you son!!!
