Water resources and water footprint of the production and consumption in Madrid region were estimated, considering blue water (water resources), green water (soil moisture), grey water (polluted water) and virtual water (water trade in products imported and exported in the region). Water resources in Madrid relay mainly in surface waters and rainfall, so the periodic occurrence of meteorological droughts implies the scarcity of water supply. The main users of blue water are households, municipalities and agriculture. Production water footprint is approximately 2,000 hm3 per year, almost four times the blue water available resources in the region. Consumption water footprint is around 9,000 hm3 per year from which 80% is net imported virtual water, so Madrid depends on external water resources in order to supply the actual consumption needs. These should be more sustainable reconsidering the consumption pattern, as 60% of the water footprint is due to meat production. | |
