E-book On Water
Water falls from the heavens, runs into streams, flows into groundwater, feeds lakes, then evaporates. It fuels biodiversity, sustains our crops and animals, helps generate energy and supports our towns and villages. Its scarcity affects people’s daily lives, even if we tend to forget this all too often in the developed world, as water treatment and distribution investment have brought us water on demand – though not always drinkable – through taps in our homes.We now effectively use water to feed ourselves, as most water (around 69%) is used by agriculture. The irrigation of 20% of farming land makes it possible to produce 40% of our food. Household water use represents just 12% of total consumption.
