Agriculture accounts for the vast majority of human water use, and is also responsible for contamination of groundwater, lakes, and rivers in many places around the world. But we need to grow food! How can we grow enough food for an increasing global population (and make sure everyone has enough food), while reducing our impact on land and water?

The answers are complex and involve choices about what foods we eat, as well as where and how we grow it. Of course, these questions touch other issues in addition to water (energy, land, food sovereignty, community stability, etc.), but here we use water quantity and quality as a lens on these questions.
