On Tuesday 15 April, at 6 p.m., Roca Barcelona Galelly hosts the lecture "Lʼaigua que mengem" (The water we eat), given by Narcís Prat, professor of Ecology at the University of Barcelona, head of the Research Group on Freshwater Ecology and Management (FEM) and researcher at the Water Research Institute of UB.

On his speech, Prat will explain that we need 6,000 litres of water to produce the food we eat and the things we use in our daily life, although our meter at home indicates that we only use 150 litres. Prat will prove that most water consumption comes from virtual water; the consumption of virtual water varies notably according to the degree of economic development of each country.

Those present are requested to bring a piece of food and an object they use at home to make a practical activity. The total consumption of virtual water needed to make these products will be calculated.

The activity "Lʼaigua que mengem" is part of the project La ciència de lʼaigua (The water science), of La UB Divulga, co-organised by the Scientific Culture and Innovation Unit (UCC+I) of UB and Roca. The main objective of the project is to make a transversal and multidisciplinary analysis of water by means of a series of lectures pronounced by UB experts on diverse subject areas: physical geography, ecology, microbiology, history, economics, law, chemical engineering and geochemistry.

Activities are free and opened to the general public but registration is required.
