The global food and beverage sector has been called “The thirsty business” due to the amount of water that is consumed in its production processes. Over 70% of the world’s freshwater withdrawals are for agriculture. This is unsustainable if we are to avert a future global water crisis. This article outlines the key problems and suggests what can be done to overcome them.
More than 70% of global water use is down to the production of food and drink. This rises to over 90% in some developing countries. Water is crucial in every stage of food and beverage production, from the initial farming to produce the raw goods to the processing, transportation and retail of the final product we see on the shelves.
Most people don’t see the hidden amount of water, or virtual water, involved in producing food and beverage. But it’s excessive. For example, it takes over 15,000 liters to produce a kilogram of beef and 140 liters of water for just a single cup of coffee.
With global population predicted to increase by 2 billion by 2050, the pressure on our water supply due to food demand will only increase unless we rethink how we use water in food and drink production processes.
The problem of over-use of water in agriculture and food processing is something that needs to be tackled at multiple levels – national, international, sector and individual company. While countries and international bodies focus on legislation and targets, companies can focus on becoming leaders and innovators in the area of water sustainability.
Measures that can be put in place to reduce water footprint include:
Businesses are starting to shift towards more sustainable strategies but recent reports still find that insufficient action is being taken. Among large global food companies, Unilever, Nestle, and Mars are among the front runners according to Feeding Ourselves Thirsty. Packaged food and beverage industries are the best performers but agriculture and meat industries lag behind. France currently leads the way from a country perspective regarding food sustainability, followed by the Netherlands and Canada. Belgium ranks 35th.
This Belgian brewery worked with water sustainability experts to reduce its water footprint by around 25%. Brewing beer is a water-intensive process, with water not only used as a product ingredient but also involved in cleaning and rinsing of machinery. In order to reduce water consumption, De Leite commissioned a full water audit which identified potential water savings. These included refining production, cleaning and cooling processes, using smart meters to better monitor use, and utilizing rainwater supplies. The result was to reduce the amount of water used to 4 liters per one liter of beer produced.
