Why Aqueduct Food? Because agriculture withdraws 70% of world’s freshwater Withdraws 30% 70% Agriculture Other

Why Aqueduct Food? Because ¼ of world’s cropland is in areas of high water stress

What is Aqueduct Food? Aqueduct Food is a global, interactive education and planning tool to help government agriculture and trade officials, international development agencies, and corporate supply chain managers identify long-term waterrelated threats to and opportunities for food security
