For the InstructorThese student materials complement the Future of Food Instructor Materials. If you would like your students to have access to the student materials, we suggest you either point them at the Student Version which omits the framing pages with information designed for faculty (and this box). Or you can download these pages in several formats that you can include in your course website or local Learning Managment System.

Module 4.1: Water Resources and Food Production
How much water do you eat? Water is essential for food production. In this unit, you will learn about water as an essential ingredient to grow the food that we eat, including plants and animal products. The concepts of photosynthesis, evapotranspiration, and crop consumptive water use are introduced followed by an overview of the spatial variability of precipitation and the resulting need for irrigation. The final activity will introduce you to virtual water embedded in the food you eat and your water footprint.
The short animated video that follows was produced by the United Nations' Water group for World Water Day and illustrates how much water is embedded in a few different food products. The numbers are given in liters, so it's helpful to remember that there are 3.8 liters per gallon. A liter is a little bigger than a quart. In this module, we'll look at why it takes so much water to produce food and you'll estimate how much water you eat.
