Water's role in food security focus of World Water Day 2012Listen /
If the world is to produce enough food to feed its seven billion (and counting) citizens, then better water management in agriculture is in order.
According to the Food and Agriculture Organization (FAO), the sector accounts for 70% of all water use. Water is needed for everything from growing crops to raising livestock, which eventually become the food that ends up on our tables.
On World Water Day, observed 22 March, FAO warns: "The world is thirsty because we are hungry."
