Water Footprint = Wine from WaterWater Footprint = Grapes and Wine from WaterWater Footprint = Water for Wine

摘要

During the past season, with many people living in the Western Cape trying to survive with a mere 40 to 50 ￡ of water per person per day, many figures were quoted reminding us just how much water is commonly used in our daily living. For example, that about 19 ￡ of water is used for a 90-second shower and that one flush of your toilet will use 9 ￡. Many people were also surprised to realise just how much water they "consume" through eating their daily food. For example that it takes 132 ￡ of water to produce a single cup of coffee (125 m￡), 196 ￡ for a large (60-gram) egg and 18 ￡ of water for a slice of bread of 30 grams. For supper, your 200 g steak will cost you 3083 ￡ of water and your small (125 m￡) glass of wine 109 litres. But the question is: what do these values really mean and do they matter?
