Water Consumption of Potatoes Vs Beef

As much as 2bn tonnes of food are wasted every year - equivalent to 50% of all food produced - according to a report published today by the Institution of Mechanical Engineers (IME)
The IME estimate that xxx-50% (1.2-2bn tonnes) of all food produced is "lost before reaching a homo tummy". Consumer affairs contributor Rebecca Smithers writes today:
The UK's Institution of Mechanical Engineers (IME) blames the "staggering" new figures in its assay on unnecessarily strict sell-by dates, purchase-one-get-1 free and Western consumer demand for cosmetically perfect food, along with "poor engineering and agricultural practices", inadequate infrastructure and poor storage facilities.
Major supermarkets have also been blamed for food waste by rejecting crops of edible fruit and vegetables which don't meet their exacting standards for their physical characteristics (such equally size and colour). Up to 30% of the United kingdom of great britain and northern ireland's vegetable ingather is never harvested due to this blazon of practice the report claims.
The publication entitled 'Global food: waste matter not, desire non' also aims to highlight the wastage of energy, state and water. Approximately 3.8tn cubic metres of water is used past humans annually with 70% being consumed by the global agriculture sector. The amount of h2o wasted globally in growing crops that never reach the consumer is estimated at 550bn cubic metres.
IME merits that h2o requirements to see nutrient demand in 2050 could reach between 10-13.5tn cubic metres per year - well-nigh triple the current amount used annually past humans.
Meat production requires a much higher amount of h2o than vegetables. IME state that to produce 1kg of meat requires between 5,000 and 20,000 litres of water whereas to produce 1kg of wheat requires between 500 and 4,000 litres of h2o.
The table below shows typical values for the volume of water required to produce mutual foodstuffs. Chocolate tops the list with 17,196 litres of water need to produce 1kg of the product. Beefiness, sheep and pork meat all crave loftier volumes of water for production as well. Tea, beer and wine use the to the lowest degree according to the listing. Compared to the production of meat, vegetable foodstuffs require considerably less water - 1kg of potatoes for example uses 287 litres of water.
Await at the table below to see how much water is required to produce a selection of mutual foodstuffs. Also if yous want to see how much h2o we consume indirectly through eating and drinking different foods, we accept previously published a great interactive visualisation by Italian graphic design specialist Angela Morelli.
