Given the trends of developments in demographics and the economy, managing and governing water resources represents one of the greatest global challenges.
Water consumption must be evaluated in a consideration of not only its direct form – water used in the bathroom, kitchen or for cleaning the home – but also in its “virtual” form (in terms of water footprint), estimating all the water that has been used throughout the entire life cycle of any product or service purchased. In other words, there is an “implicit” water consumption in food and consumer goods, of which people are rarely aware and which significantly affects the percentage of water used.
Concerted effort is needed to promote more rational use of water, especially in agriculture and on a personal level, by adopting water-saving diets
