Water and food security

This year, the focus of World Water Day is water and food security. We consume two to four liters of water a day, but much of it is locked up in the food that we eat. As the United Nation points out, it takes 15,000 liters of water to produce one kilo of beef. At the same time, it takes 1,500 liters of water to produce one kilo of wheat. Now consider that 1 billion people live in chronic hunger and water resources are already scarce. This year, World Water Day aims to encourage people to consume less water-taxing foods, produce more food with less water, and reduce food waste.
