In this week’s newsletter we’d like
to return to our series of articles pointing to “the future of our food.” The question on our minds this week is “Can
we feed the world…without destroying it first?”
While we didn’t intend to write an article about climate change, here we
are once again being faced with issues of climate change as it directly relates
to this question. Food First is an
organization dedicated to ending the injustices that cause hunger and helping communities
to take back control of their food systems.
Their work is centered around research, education and action. This organization was founded by Frances
Moore Lappé who, back in 1971, wrote Diet
for a Small Planet. Lappé laid out
the evidence at that time representing several key points including the fact
that there was 1 ½ times more than enough food to feed everyone on Earth,
hunger is due to poverty and not scarcity, and the way the developed world
produces and consumes food is damaging the planet. Here we are over forty years later and the
fact still remains the same that we still have enough food to feed the world
and our corporate, industrial food system continues to damage the planet. In Food First’s Summer 2017 “News &
Views” publication, they stated “…the corporate food system contributes up to ⅓ of the world’s greenhouse gases, making industrial agriculture one of the
main forces behind climate change.”2 In this week’s article we want
to face this topic of climate change and look at how we can turn the tide,
quickly, so we have a future.

The Intergovernmental Panel on
Climate Change (IPCC) predicts that “Without additional mitigation efforts
beyond those in place today, and even with adaptation, warming by the end of
the 21st century will lead to high to very high risk of severe,
widespread and irreversible impacts globally.” 3 The Global Development and Environment
Institute (GDAE) at Tufts University released Climate Policy Brief No. 4 in
April 2017 entitled, Hope Below Our Feet,
Soil as a Climate Solution.1 In their report they quote climate
scientist James Hansen who, in 1988, warned that: “If humanity wishes to preserve a planet
similar to that on which civilization developed and to which life on Earth is adapted,
paleoclimate evidence and ongoing climate change suggest that CO2
will need to be reduced from its current 385 ppm to at most 350 ppm, but likely
less than that.” They follow his quote
with the fact that atmospheric CO2 levels today exceed 400 ppm and
are still on the rise. Carbon is not the
culprit here, it is essential to our existence.
Climate change is happening because there is too much carbon in the
atmosphere and the reason it’s there is largely due to human activities. Carbon cycles in nature between five pools
where carbon is stored. Those five
places include the atmosphere, oceans, fossils, soil and our biosphere. The carbon cycle was in balance for many, many
years cycling between these pools in a way that was beneficial to all life
forms. The problems started when we
figured out how to extract carbon from fossils and use it as fuel, etc. We disrupted the cycle and threw off the
balance by putting more carbon into the atmosphere than the oceans, plants and
biosphere could cycle. The opening
paragraph in the GDAE Climate Policy Brief1 mentioned above reads as
follows:
“A major reduction
in greenhouse gas emissions is clearly needed, but there is increasing
scientific consensus that even if achieved, this will not be enough. In addition to a drastic reduction in carbon
emissions, carbon must be removed from the atmosphere. An important solution is beneath our feet—the
massive capacity of the earth’s soils to remove and store carbon from the atmosphere.”

The problem is the lack of
balance. Soil, which holds about three
times more carbon than the atmosphere, offers us hope for restoring this
balance of carbon in nature that humans have disrupted. As farmers, this excites us and truly gives
us hope. Why? Because we understand firsthand how resilient
and beneficial soil can be when properly cared for and many of these strategies
to store carbon in the soil are things we’ve been practicing on our farm for
many years now! Over 40 years ago I
(Richard) was inspired by the philosophy of Rudolf Steiner who taught me about
the value of capturing solar energy and putting it into the soil. Through the process of photosynthesis, plants
have the ability to take CO2 from the atmosphere along with water
and sunlight to turn it into nutrients for the plant that develop root
structures and carry these nutrients into the soil. The nutrients feed the biological life in the
soil and deposit carbon. Carbon rich
soil with high biodiversity is healthy, resilient soil. I quickly learned the value of cover crops
and we still make it a priority to plant a cover crop in a field as soon as we
take our main crop off. Cover crops fix
nitrogen in the soil, hold soil in place and, in the end, break down and become
part of the soil and build organic matter.
When I started planting cover crops, I did so for benefits including
increasing soil fertility and tilth and increasing organic matter in the soil
thereby increasing the resilience of the soil to hold water in a time of
drought and drain water in times of excess moisture. I never imagined we’d be in the position we
are in now where planting cover crops and other basic, natural agricultural
practices could be the key we need to regenerate and heal our broken cycle and
reverse something as big as climate change!
In contrast, “Intensive forms of farming using chemical fertilizers,
pesticides, herbicides and fungicides, are a leading cause of degradation of
soils worldwide, as are destructive grazing practices in pasturelands. But through appropriate practices that would
enhance carbon pools in soils and biota, the potential terrestrial carbon sink
capacity could be restored, essentially reversing its historic depletion, in
what has been called the ‘recarbonization’ of the biosphere.”1

There are several approaches we can
take to regenerate our soils and enhance the natural functioning of ecosystems
to rebuild what we’ve lost. The GDAE
report outlines some important regenerative strategies to increase the ability
of soils to store carbon. In cultivated soils,
strategies include things such as the use of cover crops, planting trees and
legumes to fix atmospheric nitrogen, feeding the soil with manure and compost,
decreasing erosion and soil loss from sloping soils through terracing, and
increasing soil microbiology with fungi and other microorganisms. Pasture management in animal production
systems is another important factor.
Sustainable pasture management includes planned rotational grazing which
can have a remarkable impact on regenerating pasture grasses, increasing soil
fertility, and reversing and preventing desertification of soils. We also need to consider forested
soils. There have been astounding acres
of valuable forest lands cleared for industrial farming and agricultural
purposes. We need to stop deforestation
and be promoting reforestation to regenerate degraded forest ecosystems. All of these efforts have the net benefit of
supporting the movement of excess carbon out of the atmosphere through the use
of plants and putting it back into the soil.
While it’s pretty remarkable to be able to use plants to combat climate
change in this way, there is a twofold benefit from regenerating soils. More plants on the land and more carbon
returning to the soil results in not only decreasing atmospheric carbon, but
also leads to increased soil fertility which also can have a significant impact
on production and yield as well as the quality of food. This will also help us continue to produce
food more reliably in the face of weather extremes which is our current
reality. However, remember that hunger
is not caused by scarcity but rather poverty.
“What causes hunger is not lack of food, but lack of access to decent
land and work. Most of the chronically
hungry in the world are marginalized farmers and rural workers. It is not how much we produce that is
important, but who produces it, how, and who profits. With 70% employment in agriculture in many
parts of the world, simply producing more food in countries like Kenya, Uganda,
or India will not solve hunger if there are no decent and stable livelihoods in
the countryside. Industrial farming
displaces workers—so many we would need unrealistically fast economic growth,
evenly spread around the globe to create enough jobs to employ all the world’s
peasant farmers. To end hunger, we don’t
need to produce more crops per se—we need to produce more decent livelihoods.”5 We need to turn food production back over to
small farmers, thereby giving them food security by giving them their jobs back
and allowing them to preserve their cultural heritage and feed their own local
markets and be part of their local economy.
In this manner human needs are met in a way that restores ecosystems and
communities instead of degrading them.
It’s an obvious win-win situation!
We’d encourage you to read the GDAE’s policy brief for yourself as there
are more details and benefits from employing these strategies than we can fully
report on here and truly does offer us hope.
We need to face the realities that industrial agriculture has no place
in the future of our food system.
Eliminating this form of agriculture would gain us great strides in
combating climate change, but furthermore if it were traded for regenerative
farming practices we would actually be able to make some headway. The answer to our original question is “Yes,
we can feed the world without destroying it.”
The question now is “Will we?”
If you’d like to learn more about
how the soil can lead us in regenerative efforts to combat climate change as
well as see some examples of how other countries are implementing action and
incentives for this purpose, we’d like to suggest the following resources:
- "The Soil Story", a video by Kiss the Ground that clearly summarizes the carbon cycle and the role of regenerative agriculture in less than 4 minutes! If you do nothing else, watch this short video.
- Soil 4 Climate is a nonprofit organization that is an advocate for soil restoration as a climate solution. They have a lot of informative resources available on their website for both education as well as action.
- Global Development & Environment Institute (GDAE) at Tufts University offers expertise in the areas of economics, policy, science and technology as they relate to global development and issues related to the environment. They have numerous publications available on their website including the Climate Policy Brief we cited above, Hope Below Our Feet.
