Resumen
Water footprint assessment is an analytical tool that helps us understand how activities, actions, and products from human activity influence the scarcity and pollution of water resources. The objectives of the paper are to study the water footprint that is necessary for the production of food for human consumption as an effective way to determine how food habits put pressure on water resources and to identify ways to reduce the stress found on them. To calculate the water footprint of food products consumed by Romanian residents, two types of data were used: information on the average annual net food consumption of each type of food considered during the research and the water footprint per unit of food consumed. In addition, an analysis was carried out based on the structure of the water footprint and the structure of food consumption. In terms of the structure of the water footprint, the contribution rate of the green water footprint is the highest, reaching 83.5%. This is followed by the blue water footprint and the gray water footprint, accounting for 9.04% and 7.46%, respectively. From the perspective of the structure of food consumption, the consumption of cereals, meat, milk, and dairy products contributed the most to the water footprint of residents? food consumption, reaching 21.8% and 26.6%, respectively, and contributing 24.2% to the total water footprint of food consumption. Our research is useful for water management, improving the efficiency of use in agricultural technologies, and optimizing the structure of food consumption, such as reducing grain and meat consumption.
