The Invisible Water in Our Food
Did you know that producing 1 kilogram of beef can require up to 15,000 liters of water? Meanwhile, plant-based foods like legumes, grains, and vegetables generally require significantly less. This means that our everyday choices—what we cook for dinner, what we pack for lunch, what we serve to our families—directly impact global water resources.
We need to raise awareness about the fact that water is not just something we drink: we eat it, every single day.
Therefore our daily food choices, food preparation and cooking can be considered as a powerful climate action.
And as a climate action, this one feels very close to our students as it is not distant, overwhelming and abstract, but something truly tangible and personal.
Cooking as a Climate Action
The core of The Kitchen Adventure programme is that when students, families, or communities start experimenting with more sustainable ingredients, they are not just learning recipes—they are shaping a more resilient future.
Simple shifts can make a big difference, such as choosing more plant-based meals, reducing food waste, cooking seasonally and locally and using water effectively in the kitchen. These actions reduce the pressure on water systems while also supporting healthier diets.
Water, Food, and Equality
On this year’s World Water Day, the global theme highlights the connection between water and equality. And food plays a key role here too. In many parts of the world, women and girls are responsible not only for collecting water, but also for preparing food. This means that water scarcity directly affects nutrition, time, education, and opportunities. By rethinking how we produce and consume food, we are also contributing to a more fair and inclusive system.
Join the Sustainable Foodtruck Challenge
To inspire discussions about the water footprint of food in the classrooms, this World Water Day we invite educators to try out our lesson plan "The Sustainable Foodtruck Challenge".
In this challenge, students design their own “foodtruck concept” with a mission:
create delicious, appealing meals with a low environmental footprint—especially when it comes to water.
Participants will:
- explore the water footprint of ingredients
- design menus with sustainability in mind
- develop creative food concepts
- present their ideas to others
