Water - Our Most Precious Resource

"We forget that the water cycle and the life cycle are one."
Jacques Cousteau (1910-1997)

"When the well's dry, we know the worth of water."
Benjamin Franklin (1706-1790)

  • Of the world’s water resources, only 2.5 % is fresh water.
  • Of this fresh water, only about one third is available for human use with the rest contained in polar ice caps and glaciers.
  • The world's food production depends on the availability of water, a precious but finite resource.
  • Today, irrigation covers about 20 percent of the world’s cropland, and it contributes 40 percent of total food production.
  • Irrigated agriculture is responsible for approximately 70 percent of all the freshwater withdrawn in the world.
  • More water will be used for irrigation in the future, as world food production continues to increase to meet demand.
  • The challenge for irrigated agriculture today is to contribute to the world’s food production and improvement of food security through a more efficient, cleaner and integrated use of water. (Land and Water Division, Food and Agriculture Organisation, Rome 2002).
