How Much Water a Pound of Beef

Facts almost h2o employ and other ecology impacts of beefiness product in Canada

Yes, information technology takes water to produce beef, but in the 2.5 million years since our ancestors started eating meat, we oasis't lost a drop yet.

Based on the most recent science and extensive calculations of a wide range of factors, it is estimated that the pasture-to-plate journey of this important protein source requires about 1,910 U.s.a. gallons per pound (or fifteen,944 litres per kilogram) of h2o to get Canadian beef to the dinner table. That's what is known as the "water footprint" of beefiness production.

That may sound like a lot, just the fact is information technology doesn't thing what crop or creature is being produced; food production takes water. Sometimes it sounds like a lot of water, but water that is used to produce a feed crop or cattle is non lost. H2o is recycled – sometimes in a very complex biological process— and it all comes back to be used once more.

Water requirements vary with brute size and temperature. But on average, a 1250 pound (567 kg) beefiness steer only drinks virtually 10 gallons (about 38 litres) of water per day to support its normal metabolic function. That'due south pretty reasonable considering the average person in Canada uses most 59 gallons (223 litres) per day for consumption and hygiene. And according to the most contempo Statistics Canada data, Canada'south combined household and industrial employ of water is most 37.ix billion cubic meters annually (a cubic meter equals well-nigh 220 gallons or 1000 litres of water) — we humans are a h2o-consuming agglomeration.

Researchers at the University of Manitoba and Agronomics and Agri-Food Canada (AAFC) Lethbridge found that in 2011, producing each unit of measurement of Canadian beef used 17% less water than thirty years prior. ⁽¹⁾ It also required 29% less breeding stock, 27% fewer harvested cattle and 24% less land, and produced fifteen% less greenhouse gases to produce each pound or kilogram in 2011 compared to 1981.⁽²⁾

But back to the beef industry — agronomics in general and beef producers specifically have oftentimes been targeted every bit being loftier consumers, even "wasters" of water, taking its toll on the surroundings. However, there's a lot more to this story – information technology's non equally elementary as ane,910 gallons of water beingness used for each pound of edible beefiness produced.

If the beefiness animate being itself simply needs about 10 gallons of h2o per twenty-four hours to function, what accounts for the rest of the water (footprint) required for that 16 oz steak? Often in research terms the h2o measured in the total h2o footprint is broken into three colour categories. The footprint includes an estimate of how much surface and ground (blue) h2o is used to h2o cattle, brand fertilizer, irrigate pastures and crops, process beef, etc. And then there is a measure of how much pelting (dark-green) water falls on pasture and feed crops, and finally how much water is needed to dilute runoff from feed crops, pastures and cattle operations (grey water). Adding these blue, green and grey numbers for cattle produced throughout the world produces a global "water footprint" for beef. It is worth noting that more than 95% of the water used in beef product is light-green water — it is going to rain and snowfall whether cattle are on pasture or not. And it is important to remember of all water used one way or another information technology all gets recycled.

If y'all expect at the life cycle of a beefiness animal from birth to burger or pasture to pot-roast, the ane,910 gallons per pound is accounting for moisture needed to abound the grass it volition eat on pasture and for the hay, grain and other feeds it volition consume as it is finished to market weight. Information technology also reflects the water used in the processing and packaging needed to get a whole brute assembled into retail cuts and portion sizes for the consumer. Every step of the process requires water.

Since the objective is to produce poly peptide, couldn't we just grow more pulse crops such equally peas, beans, lentils and chickpeas and still see protein requirements, employ less water and do good the environment? Let's take a look at why that theory doesn't agree true.

Water is only part of a very large picture

First of all, whether information technology is an almanac crop (such as wheat, canola or peas) or some type of permanent or perennial forage stand (like alfalfa or bromegrass) consumed by cattle, all crops need moisture to grow. (And as we talk about unlike crops in the next few paragraphs, it is important to annotation there are two master types. About field crops such as wheat, barley and peas are annual plants. They are mostly seeded in the leap, get harvested in the fall and then die off as winter sets in. Most pasture and forage crops are permanent or perennial plants. Native or natural grass species seemingly live forever, while tame or domestic provender species will remain productive for at to the lowest degree two or three years and oft for many years earlier they need to be reseeded.)

Both annual crops and forages are important in Canadian agriculture. Only, when people wonder why we just don't produce more plant-based protein by growing  more than peas, beans and lentils, it's not simply a thing of swapping out every acre of pasture to produce a field of peas. It'south a matter of playing to your strengths — recognize the potential of the land for its best intended purpose.

Annual pulse crops (like peas, beans and lentils) use more water than grass. For dry pea production, for example, it takes about 414,562 gallons of h2o per acre of land to grow peas. Compare that to total Canadian beef production of about 2.46 million pounds of beefiness produced on most 57 million acres land to grow the pasture, forage and other feed for the cattle herd, and it works out to virtually 78,813 gallons per acre of country used for beef production.

This means that not every acre beef cattle are raised on is suited to crop production . Dry peas need more than v times as much water per acre (414,652 ÷ 78,813 = 5.three) than the grass does. Much of the country used to raise forage for beef cattle doesn't receive adequate moisture or have the right soil conditions to support ingather production, but it can produce types of grass that thrives in drier conditions.

Beef industry plays an important diverse office

The fact is, today's beefiness cattle were not the showtime bovid species to gear up foot on what we now consider Canadian agricultural land. For thousands and thousands of years herds of as many equally thirty million bison roamed across North America, including Canada, eating forages and depositing nutrients (manure) dorsum into the soil and living in ecological harmony with thousands of institute and animal species.

Today, the five meg caput of beef cattle existence raised on Canadian farms tin't indistinguishable that natural system, but as they are managed properly they exercise provide a valuable contribution to the surround merely as the bison did.  Beef cows and the pastures they apply help to preserve Canada's shrinking natural grassland ecosystems by providing plant and habitat biodiversity for migratory birds and endangered species, every bit well as habitat for a host of upland animal species. Properly managed grazing systems as well benefit wetland preservation, while the diversity of plants all aid to capture and store carbon from the air in the soil.

Where do cattle fit?

Forages (pastures and harvested roughage) account for approximately fourscore per cent of the feed used by beef cattle in Canada. Most a third (31 per cent) of Canada'south agricultural land is pasture. This state is not suited for almanac crop product, simply it tin can grow grass, which needs to be grazed by animals to remain growing and productive.

Canada'southward beef herd is primarily located in the prairies. The southern prairies are drought-decumbent, and the more northerly growing seasons are likewise short for many crops. Primal and Eastern Canada generally take higher rainfall and longer growing seasons than the prairies, but not all this farmland is suitable for crop production either. Much of this country is too boggy, stony, or bushy to allow cultivation, merely information technology tin grow grass. Grass that cattle live on for virtually of their lives.

Grass and other range and pasture plants incorporate fiber that people can't digest, merely cattle take a specialized microbial population in their tummy (rumen) that allows them to digest fiber, make utilize of the nutrients, and convert them into high-quality protein that humans tin digest. Beef cattle production allows usa to produce nutritious poly peptide on state that isn't environmentally or climatically suited to cultivation and crop production.

Water cycles

Only focusing on water utilize per pound of product ignores the h2o cycle. The water cycle is important – humans, wheat, corn, lentils, poultry, pork, eggs, milk, forages and beefiness production all utilize water,just they don't use it upwards . They aren't sponges that endlessly blot water. Nearly all the water that people or cattle eat ends upward back in the surroundings through manure, sweat, or water vapor.

Nosotros know that most of the water plants accept up from the soil is transpired dorsum into the air. Similar city water, the water that beef processing facilities take out of the river at one end of the establish is treated and returns to the same river at the other end of the plant. New technologies to recycle and re-employ water can reduce the corporeality of water needed for beef processing by 90 per cent.

Storing greenhouse gases

Plants — pasture and hayland, all crops really — help to capture and store carbon. Plants have carbon dioxide out of the temper, incorporate the carbon into their roots, stems, leaves, flowers and seeds, and release oxygen back into the atmosphere. Because perennial plants (well-nigh hay and pastureland) live for many years, they develop an all-encompassing root system which will eventually decay and get part of the soil carbon. Considering these permanent or perennial pastures are not cultivated and reseeded every year, the carbon sequestered by these plants remains in the soil rather than being released back into the atmosphere. As a result, numerous studies have documented that grasslands, which remain healthy with grazing cattle, take more carbon stored in the soil than side by side annual cropland.

Pastures protect the soil

When state is cultivated to produce almanac crops such as wheat, barley, canola, peas and lentils, the disturbance of soil releases soil carbon to the atmosphere. At that place is also the run a risk of soil erosion. In Western Canada, our predecessors learned this the difficult way. Not knowing any better about the impact of tillage of fields to produce crops, serious losses occurred across Canada —particularly notable on the prairies in the 'Muddy Thirties'. Cultivation led to the loss of twoscore-50 per cent of the organic carbon from prairie soils, and 60-70 per cent from cardinal and eastern Canadian soils. But we learned from those mistakes and today, most annual crops are grown under reduced or no-till cropping systems — crops are seeded with minimal soil disturbance. Unlike commercial fertilizers, using manure as a fertilizer also replenishes organic thing in these soils.

Maintaining permanent grassland and perennial pastures drastically reduces the run a risk of soil loss due to wind and h2o erosion, and keeps stored carbon stored in the soil. The bespeak is that cattle take an excellent fit on productive agricultural country not suited to almanac crop product.

Soil wellness improves

Getting back to the water topic, bated from benefits noted earlier, these permanent grasslands and perennial pastures in fact help to conserve moisture as roots and constitute matter aid to improve soil structure and help rain and snow melt percolate down through the soil. That'due south known as water infiltration. As a general rule, when lands are left undisturbed, just 10 per cent of atmospheric precipitation runs off the land, twoscore per cent evaporates and 50 per cent goes down into the soil to enter both shallow and deep groundwater reserves. When soils are disturbed, water infiltration is reduced.

It's not simply dead roots that provide environmental benefits. Because perennial forages aren't cultivated, and oft abound in dry conditions, they grow extensive root systems in their search for moisture.

An example of 1 important plant species is the legume family unit. There are varieties of legumes that make excellent pasture and hay crops. They are known as fodder legumes and nigh are perennial. But in that location is another whole branch of the legume family unit that humans eat at the dinner tabular array. These legumes are known as pulse crops and that includes, peas, beans, lentils and chickpeas. Most annual pulse crops are used for human being food, only even these produce by-products (eastward.yard. stems, pods, shrivelled seeds, etc.) that are not edible for humans but that cattle tin can convert to loftier quality, nutritious protein.

What's interesting about legumes is how they benefit the soil. For example, forage legumes like alfalfa develop roots that penetrate 53 to 63 per cent deeper into the soil than chickpeas, lentils, and other pulse crops. All legumes also have a natural power to produce an important soil nutrient known as nitrogen. All legumes tin can "gear up" or capture nitrogen from the air and convert it into soil nitrogen that can better soil fertility. Forage legumes can set up upward to twice as much nitrogen per acre in the soil as annual legume (or pulse) crop.

Lands that are prone to periodic flooding or drought benefit from the permanent plant encompass that forages provide. The roots and vegetation proceed the soil in place so that information technology doesn't erode, launder abroad in a flood or blow away during a drought.

Home on the range

Again, when you ask the question, why don't nosotros only abound more almanac crops, remember that cattle and soil aren't the only living things afflicted when grassland is converted to farmland. Grasslands as well provide habitat for pocket-size and large mammals, hawks, nesting birds, songbirds and pollinating insects. Converting natural grassland to crop production results in considerable biodiversity loss, as the native plants, insects, birds, and wildlife that require undisturbed natural habitats do not thrive nearly every bit well under annual cropping systems.

About of Canada's native grasslands take already been converted to crop production. This has led to considerable population losses in some species, with upwards to 87 per cent population declines amongst some grassland bird species. So maintaining grasslands and perennial pastures provides a huge ecological benefit.

Crops and cattle become well together

It is not an all or nothing scenario — crops, cattle, and grasslands demand each other. For instance, canola crops yield and ripen better when they are pollinated by bees. Because an entire field is seeded at the same time, all the canola plants flower at the same fourth dimension, and each establish but flowers for two or three weeks. Grasslands provide a domicile for a wide range of plants that all flower at different times. That means bees accept lots of plants to help support them during long periods when annual crops aren't flowering. Over 140 bee species are resident in Canadian grasslands; bee abundance and variety are positively related to the presence of grasslands.

Annual crops can also serve double duty. Canadian farmers produced virtually 8 one thousand thousand tonnes of barley in 2018. A portion of that was seeded to what's known equally malting barley varieties that produce barley suitable for the brewing industry. If the grain doesn't run into specifications for brewing standards (for weather-related reasons, for instance), information technology can still be used as good quality livestock feed. Information technology's a similar situation with the 32 1000000 tonnes of wheat produced annually. If information technology doesn't run across milling, export or other industrial finish-use standards, it can exist used as good quality feed for cattle.

All part of a organization

To repeat, yep it takes water to produce beef, only on a broader scale, beefiness cattle are a vital part of an integrated system. Cattle need grass, grass needs grazing to remain vital, grass protects the soil, salubrious soil helps to conserve moisture, plants provide feed and habitat for a myriad of species, grains non suitable for the human-food market make splendid livestock feed, cattle manure provides a valuable natural fertilizer to pastures and crops, and the whole system results in production of a high quality, salubrious protein source for humans.

All food systems rely on water, simply the most important thing to remember is the water is not used up. All water ultimately gets recycled.
