  2. 2. INDEX  Water  Uses of water  Water cycle  Water footprint  Component of water footprint  Water footprint of the product  Invention of water footprint  Facts of water  Ways t reduce water footprint
  3. 3.  Water is a transparent fluid which forms the world's streams, lakes, oceans and rain, and is the major constituent of the fluids of living things. As a chemical compound ,a water molecule contains one oxygen and two hydrogen atoms that are connected by covalent bond.
  4. 4. USES OF WATER 1. agriculture work 2. industrialization 3. urbanization 4. daily activities 5. drinking 6. household purpose
  5. 5. WATER CYCLE The water cycle, also known as the hydrologic cycle or the H2O cycle, describes the continuous movement of water on, above and below the surface of the Earth. The mass of water on Earth remains fairly constant over time but the partitioning of the water into the major reservoirs of ice, fresh water, saline water is variable.
  6. 6. WATER FOOTPRINT  A water footprint is basically the total amount of water a country or a nation or a particular area or a particular human being uses.  Water use is measured in water volume consumed (evaporated) and/or polluted per unit of time.
  7. 7. Within the water footprint concept, Water Footprint Network splits water footprints into three corresponding elements: 1. Blue water footprint 2. Green water footprint 3. Grey water footprint COMPONENTS OF WATER FOOTPRINT
  8. 8. Product Amount in Litres Amount in Gallons 1 cup of tea 32.4 l 8.6 US gal 1 imperial pint of beer 160 l 42.3 US gal 1 glass of wine 120 l 31.7 US gal 1 glass of milk 200 l 52.8 US gal 1 kilogram (2.2 lb) of beef 15,000 l 3,962.6 US gal 1 kilogram (2.2 lb) of poultry 6,000 l 1,585.0 US gal 250 grams (8.8 oz) packet of M&M’s 1153 l 304.6 US gal 575 grams (20.3 oz) jar of Dolmio pasta sauce 202 l 53.4 US gal WATER FOOTPRINT OF THE PRODUCTS
  9. 9. INVENTION OF WATER FOOTPRINT  The water footprint concept was introduced in 2002 by Arjen Y. Hoekstra fromUNESCO-IHE as an alternative indicator of water use.The concept was refined and accounting methods were established with a series of publications from two lead authors A.K. Chapagain and A.Y. Hoekstra.
  10. 10. FACTS OF WATER  Roughly 70 percent of an adult’s body is made up of water.  At birth, water accounts for approximately 80 percent of an infant’s body weight.  A healthy person can drink about three gallons (48 cups) of water per day.  82% of those who lack access to improved water live in rural areas, while just 18% live in urban areas.
  11. 11. WAYS TO REDUCE WATER FOOTPRINT  Broadly speaking, you can reduce your direct water footprint by:  installing water saving toilets;  applying a water-saving showerhead;  turning off the tap while brushing your teeth;  using less water in the garden; and  by not disposing medicines, paints or other pollutants through the sink.
