FOOD raised agro-ecologically in Grey County, Ontario
Broadly defining what we mean by “sustainability”. Mostly focussed on permaculture concepts but also includes economic sustainability since you can’t build a sustainable farm if you have to sell the farm to pay the bills.
As the title suggests the article chronicles how we got to where we are. Space didn't let the article explain much about why we think the issues we are trying to address are so important. I will try to express those ideas in the Big Picture section of our website as time allows.
An abbreviated version of this article was also published in the newsletter National Farmers' Union local 344 (Grey county) sends to its members.
While carbon dioxide (CO2) and nitrous oxide (N2O) are active in our atmosphere for many human generations, methane – a powerful, but short-lived, greenhouse gas – is broken down in about a decade. This means that the methane emissions of a herd of 100 cows today are simply replacing the emissions that were first produced when that herd was established by a previous generation of farmers. There was an initial pulse of warming when the herd was established, but there is no ongoing warming from that herd.
Under the new, updated metric, GWP*, the greenhouse gas emissions from UK agriculture fall from 46.5 MtCO2e [millions of metric tonnes of carbon dioxide equivalent] in 2016, to just 9.5 MtCO2e*. Warming from CO2 and N2O across that period are the same as previously reported, but methane is recalculated as -10.6 MtCO2e*. That’s a negative emission value, because methane levels have fallen since the base year of 1996.
The transformation in the results is staggering. By accurately measuring the impact of methane, agriculture’s emissions under GWP* are just 20% of their original value.
Cattle and sheep are not the enemy – instead it’s high-yield, high-fodder (maize [corn], soy and cereal) production systems, which are driving humanity towards the precipice. Benefits under GWP* are gained through well-managed grass-based agriculture; by a diverse patchwork of rural businesses, and the restoration and maintenance of rural economies. We can still eat meat and dairy, as part of a new era diet that includes greater nutritional diversity, but also restore natural balance on all farm land.
The research was conducted by "...a global team of IPCC [Inter-governmental Panel on Climate Change] researchers based at Oxford University" and "...was well received at COP 24 in Katowice". Here is the peer-reviewed source article published in the June 2018 edition of Climate and Atmospheric Science and here is the four page brief.
The big benefits come from "well-managed grass-based agriculture". That means ruminants such as cattle, sheep, goats, bison, and horses (who eat grass but technically aren't ruminants). It further means grass only like Better Together Farms' beef.
Most of the other ways humans get our calories and protein are worse for the environment. Pork and poultry are almost always fed rations composed mostly of corn, soy, and cereals. There are no wild sources of seafood which have not already been overfished, and farmed salmon have been genetically modified so they eat corn. Soy weighs heavily in mostly vegetarian and vegan proteins (including new meat-like products). Almost all the food for sale in grocery stores outside of the produce section is mostly made of corn and soy.
Grass only dairy is the holy grail of grazing: it is very difficult to manage cattle and pastures to approach the high output of intensified dairy operations.
If we ever stop externalizing pollution and other environmental impacts from economics, expect to pay about what I charge for food. The currently dominant model of agriculture in Canada is fossil fuel intensive, using 10 calories of fossil fuel for every calorie of food produced. Economic imperfections lead industry groups and governments to believe that this is an optimal or necessary way to feed our society. If we include the externalities so everyone sees the true and total costs of production, then cheap food won't be nearly so cheap.
The finding in this article (and both current and revised methodologies for measuring climate change impact) does NOT account for the additional environmental benefits of carbon sequestration caused by soil fertility improvement of cattle managed the way we manage at Better Together Farms.
Last week marks the second birthday of the first animals born on our farm. The steers (castrated males) Beardo and Little Will were born April 24 and 22 respectively, and Siibi the heifer (female who has not yet had a calf) was born April 12.
It has been a juggling act ensuring that the cattle get enough to eat as they rehabilitate our depleted fields, but as you can see below Beardo has grown into a fine young fellow eclipsing his mom, Koko.
Given that the cows weigh about 500 kg, I would guess Beardo is closer to 600 kg -- a very respectable weight for a Black Angus steer, and that is before finishing him (fattening him up) on the spring flush of grass.
To paraphrase the schoolyard taunt "bet my two year old can beat up your two year old" :-). Looking forward to 100% grass-fed Black Angus beef this August.

Think about it: our food supply is measured in days, weeks and, at best, months. The oceans are over-fished and hydroponics can't scale up. Lose our ability to grow food on the land and this is how long we have to live. Because of their importance, the UN has declared 2015 as "the international year of soils".
