Today, March 22, is United Nations World Water Day. Each of us drinks 1/2 to 1 gallons (2 to 4 liters) of water a day. As the UN points out, we get most of that water from the food we eat: It takes 3,900 gallons (15,000 liters) to produce 2.2 pounds (1 kilogram) of beef and about 400 gallons (1,500) liters for the same amount of wheat.
With 7 billion people living on earth today and another 2 billion expected by 2050, water and food resources are, and will be, under pressure. Moreover, global warming has led to environmental changes all over the world with effects on wildlife, rising temperatures, more frequent wildfires and more, notes Oxford University Press’s blog. All of these changes affect and could even endanger food production.
In view of all this, United Nations World Water Day seeks to raise awareness about the importance of freshwater and the need for sustainable management of freshwater resources. This year’s World Water day focuses on water and food security. According to the UN, it takes an average of 792 gallons (3,000 liters) to produce the food needed for just one person a day. Currently 12 percent of the world’s land is used for agriculture and 70 percent of the water from aquifers, streams and lakes for the cultivation of of farmland.
Here are some of the UN‘s proposals to increase water, food and nutrition security.
