 3.2 Enviromental indicators            3.2.1 The Water Footprint





 Environmental indicators are simple
 measures that tell us what is happening to   Water  impacts  can  also  be
 our environment. Criteria and frameworks        measured as the water
 are used to help people in their decisions.   footprint (Baldwin 2015, 21).

 Harmaala  &  Jallinoja  (2012,  134-135)  say  that  environmental  burden
 of  products  and  services  can  be  measured  by  the  so-called  “ecological
 backpack”  method.  “Ecological  backpack”  tells  you  about  the  amount  of
 material needed to make a product. This is often called ecological footprint.   http://waterfootprint.org/en/

 The  “Ecological  backpack”  measurement  can  illustrate  the  ecological
 footprint easily. Harmaala & Jallinoja (2012, 135) continue that also often
 counts  the  carbon  footprint  which  tells  about  the  product  life  cycle.  The
 carbon footprint is expressed as mass, that is, the total amount of carbon
 dioxide  or  carbon  dioxide  equivalents  most  often  in  kilograms  or  tons.       The water footprint is an indicator of water use that looks at both the direct and
                                                                   (Harmaala & Jallinoja, 2012, 135.)  indirect water use of a consumer or producer. In the water footprint calculator

 Since the environment is very complex, indicators provide a more practical   food consumption is the largest contribution. The Water footprint was created
 and economical way to track the state of the environment than if we attempted   in  2002  by  Professor  Arjen  Hoekstra  from  the  University  of  Twente  in  the
 to record every possible variable in the environment.   Netherlands.

 Example: Clean water

      Why water footprint is important? Because, clean freshwater is important to all
      of us, but a significant part of world population does not have clean water. This
      situation is protracted to get worse. Baldwin (2015, 20-21) says that it will be
      evident that over 60% of population will be out of clean water in the future.  All
      food production needs water. Therefor agriculture is responsible for using 2/3
      of our fresh water.
