Know Your Water Footprint In The Kitchen and Beyond
Water security has never been more topical than it has in recent years. Following the devastating droughts that have plagued the Western Cape, we’ve had to drastically change the way we think and use water, especially in the kitchen. Waterless cooking – cooking with little to no water – should absolutely part of our daily routine.
Did you know? March 22nd 2019 is World Water Day . The focus is on the importance of freshwater and advocating for the sustainable management of freshwater resources. The theme for 2019 is ‘Leaving no one behind’. worldwaterday.org
Just as we have become aware of our carbon footprint, equally, we need to consider our water footprint. The water we use for cooking goes beyond what we use in our kitchens. Every ingredient comes with its own ‘water’ price tag, from the amount used to grow and harvest, until, eventually, it ends up on your dinner table as a (hopefully) delicious meal.
Why it’s important to know your water footprint
What’s scary is that there is enough water for everyone on earth. The problem is that it’s unevenly distributed, wasted and or unsustainably managed. Which is why it’s so important for water-scarce cities like Cape Town to know and watch their water footprint.
What is a water footprint?
Simply put, your water footprint is the total amount of water needed to make the end product. It takes into consideration the whole supply chain and the water used either directly or indirectly to produce.
Why you should be thinking beyond your kitchen when cooking
As consumers in our modernised society, where produce is readily available all year round, we are seldom forced to stop and think about what resources went into an item unless there is a crisis in price – like for example the butter price surge or a crisis in supply like our current water crisis.
The fact is, as a consumer we possess the collective power to drive demand down. Eventually, this trickles down to the farmers and supermarkets thereby reducing our footprint. We really do have the power!
Calculating Your Water Footprint
To give you an idea of how much water is used in food production, we have listed the global average of litres of water used per kilogram for 10 essential everyday ingredients most common to the South African household.
To calculate your water footprint per meal; times the value per kg by the amount consumed. So if you’re having one slice of bread weighing 0,04 kg (40 grams) your water footprint would be ± 65 l. Wait, What?!
Don’t worry, we’re not saying don’t eat more than half a slice of bread per day. Rather, we want to illustrate how much water we actually indirectly use and why it’s important to be conscious and mindful of what we consume and even waste.
Below is a list from waterfootprint.org, which shows the global average of litres of water used (both directly and indirectly) to produce the final product.

Global Avg. water used for everyday ingredients
|Beef||15 415 l/kg|
|Lamb & Mutton||8 763 l/kg|
|Pig||5 988 l/kg|
|Chicken||4 325 l/kg|
|1 egg||200 l|
|Sugar Crops||197 l/kg|
|Starchy Roots||387 l/kg|
Waterless Cooking Tips To Reduce Your Water Footprint
Fewer dishes, less cleanup = less water
Stick to recipes that use only one pot or pan, and if you must reuse the same pan for different dishes. Think oven tray cooking (don’t forget to line trays with oiled tin foil to avoid hours of scrubbing).
Invest in good quality non-stick pans and if your pots are losing their stick, check with the supplier where you can get your pan resprayed.
If you can’t get your hands on a non-stick pan, a temporary solution is to season after washing or use a spray and cook before cooking.
Say No to Boiling and Steaming
Obviously! But, if you must have rice or pasta, opt to cook them in the sauce or stock. As for steaming; pop veggies in a bowl with a tablespoon or two of water, cover with pieced clingfilm and nuke till cooked through, about 8 minutes.
If you secretly love hoarding, then this one’s for you! Legumes have a low water footprint, unfortunately, in their dry form they need soaking and boiling, but you can avoid these steps by using canned ones.
