Celebrated every year on March 22, World Water Day emphasizes the critical importance of protecting water resources. The global water crisis is not limited to drinking water and industrial use; it is also directly related to food production and consumption. Agricultural production accounts for approximately 70% of the world's total freshwater use, and the impact of individuals' dietary choices on the water footprint is increasingly being discussed.
Water Footprint and Nutrition: The Facts in Numbers
The water footprint represents the total amount of water consumed directly and indirectly during the production of a product or service. Food production accounts for the largest share of global freshwater consumption, and the impact of dietary habits on this footprint is astonishing:
-
Producing 1 kg of beef requires approximately 15,400 liters of water, while 1 kg of chicken requires around 4,300 liters.
-
The water footprint of 1 kg of cheese exceeds 5,000 liters, whereas plant-based protein sources such as legumes require significantly less water. For instance, 1 kg of lentils needs only about 1,250 liters of water.
-
Global food waste accounts for approximately 24% of total freshwater use. Every year, discarded food leads to the waste of billions of cubic meters of water worldwide.
Sustainable Nutrition for Water Conservation
Even small changes in individual dietary habits can contribute to the sustainable management of water resources:
-
Shifting towards plant-based protein sources reduces the water consumption associated with animal-based foods.
-
Preferring local and seasonal foods can lower agricultural irrigation needs.
-
Preventing food waste significantly reduces the amount of wasted water.
Steps to Protect Water Resources
-
Choosing food alternatives with a low water footprint
-
Supporting products from sustainable agricultural practices
-
Minimizing food waste at home and in the industry
World Water Day calls on all of us to reconsider the value of water, re-evaluate our consumption habits, and contribute to a sustainable future. Protecting water resources is not just a concern for today but a critical responsibility for the future of our planet.
