Two fifths of the world’s population faces water shortages. During the coming decades, water scarcity is expected to rise as a result of a rapid increase in the demand for water due to population growth, urbanization and increasing consumption of water per capita. In addition, climate change is expected to influence the supply of water, modifying the regional distribution of freshwater resources.

Promote awareness about wasted food and more healthy diets.

Helping people to understand their dependence on water may reduce the amount of wasted food, particularly in developed economies. Wasting food also implies the waste of embedded resources. Thus, wasted food is wasted water and wasted energy. As water becomes an increasing constraint on food production, more attention must be given to changing current consumption and production practices.

In addition to providing more information on wasted food and water as well as the consequences, promoting healthy diets and lifestyles and informing consumers better about food choices can be a key water-saving strategy. A diet with more fruit and vegetables and less meat, particularly beef, would be a healthier and environmentally friendly choice.
