In today's issue of The Scientist, Dr. Christiane Barranguet writes about the consequences of a shortage of potable water and why it affects people worldwide. In an article titled "Opinion: The Water Crisis," she explains:
There is enough freshwater on the planet to ensure access to clean water for everyone, but it is distributed unevenly and too much of it is wasted, polluted, or unsustainably managed. Since the flow of water respects no boundaries, related problems are often international in scope, but solutions tend to be implemented on a local level with limited coordination between the various stakeholders to optimize effectiveness.
Dr. Barranguet focuses on the connection to food production, citing research by theFood and Agriculture Organization of the United Nations:
The FAO estimates that by 2050, the world must grow enough food to support an additional 2.7 billion people — and it must do so with less water. ... While the daily drinking water requirement per person is 2 to 4 liters, it takes 2,000 to 5,000 liters to produce one person’s daily food.
