Everything you eat had to be grown somewhere, and as we all know,
it takes water for produce to grow. This includes all your fruits, veggies,
nuts, meats and drinks! The problem is, that not everyone knows that
it takes gallons upon gallons to grow whats on your dinner plate. Measuring how much
water it takes to produce something is called a water footprint. On this website,
you'll be able to calculate the water footprint of the foods you
would typically buy at a grocery store!
This is a comparison of the internal and external water footprint of consumption of agricultural products for the top ten most populated countries in the world.
External water footprint happens when the consumption lies somewhere else in the world through imported goods, meaning that you're using someone else's water. Internal water footprint, is that country using it's very own water.
Below, the graph reflects the total internal and external water footprint including the three types of water footprints.
The three types are blue, green and grey water footprint
Green water footprint: the water from rain that is stored in the root zone of the soil and used by the plants natural photosynthesis process i.e. evaporation and rainfall.
Blue water footprint: water from the ground, or a large body of water, is usually irrigated.
Here, you can see which fruits, vegetables, proteins, and beverages use the most water to produce compared to other fruites, veggies, etc. Each is represented by how many gallons you need to produce just one cup of said product.
