Food crops for biodiesel? Apparently so.

I’ve been appalled by the vast percentage of domestic corn production used to produce ethanol—nearly half.

But I had no idea food crops were also being grown to make diesel fuels—until I saw this tweet/post:

I went right to the source: Renewable Diesel Feedstock Trends over 2011-2022

The growth in renewable diesel production capacity in the U.S. was dramatic in recent years, with capacity in the last two years expanding by 1.8 billion gallons, or 225 percent (farmdoc dailyMarch 8, 2023). ..In a previous farmdoc daily article (May 1, 2023), we examined historical feedstock usage trends for the combined total of renewable diesel and biodiesel over 2011 through 2022.  Our most recent farmdoc daily article (December 11, 2023) article examined feedstock usage trends for biodiesel alone, and found that  soybean oil dominated as a feedstock for FAME [Fatty Acid Methyl Ester] production…(see the complete list of articles here).

Here’s what’s being used for biodiesel production.

I’m OK with animal fats for this purpose.  We aren’t raising animals specifically to produce biofuels.

But: Corn?  Soy?  Canola?

And don’t get me started on the implications of expanding palm oil production for this purpose, or what soybean production is doing to the Brazilian jungles.

This may be great news for Big Ag producers of these commodities, but could we please closely examine the implications of growing food for biofuels on food security, environmental degradation, water use, and climate change.

Note: The New York Times says our diets are to blame for ground water depletion--all those soybeans.  Another reason to question using soybeans to make fuel.  Biodiesel may be more energy efficient than ethanol, but growing crops for either depletes groundwater.

The COP-28 UN Climate Change Conference in Dubai—items

COP-28, the UN’s climate change conference is happening in Dubai, right now.

I’m trying to make sense of it.  For starters, the irony:

But food—the effects of agriculture on climate change (and vice versa) is on its agenda this year—a major big deal.

That’s why a coalition of farmers, communities, business, and philanthropy has issued a call to transform food systems.

Here’s my collection of food-related items.

I.  Food Tank’s Danielle Nierenberg is on the job: more than 30 Food Tank partnered events are scheduled.

Once again, four pavilions will be devoted to food systems: Food and Agriculture, led by our partners and friends at FAO, CGIAR, International Fund for Agricultural Development, and The Rockefeller Foundation; Food Systems, spearheaded by the European Union-backed program EIT Food and a variety of other groups including the Food and Land Use Coalition; Food4Climate, organized by a variety of partners—including youth voices—pushing for a more humane and sustainable food system; and the Sustainable Agriculture of the Americas Pavilion facilitated by IICA, bringing together the global north and south across the hemisphere.  You can read Food Tank’s coverage of the roadmap, which was announced last year, here.

IIFoodDive: Food system transformation on the menu at COP28

III.  Reuters: Countries urged to curb factory farming to meet climate goals

IV.  The lunch menu: The summit is featuries roughly two-thirds plant-based menu to highlight the link between greenhouse gas emissions and livestock.  But the meat industry is fighting  back.

V.  DeSmog: Big Meat Unveils Battle Plans for COP28

VI.  The Guardian: Plans to present meat as ‘sustainable nutrition’ at Cop28 revealed: Documents show industry intends to go ‘full force’ in arguing meat is beneficial to the environment at climate summit.

VII.  The Meat Institute

The Meat Institute and the Protein PACT for the People, Animals & Climate of Tomorrow will highlight animal agriculture’s commitments and progress toward global goals in multiple high-level engagements at the UN Climate Change Conference (COP28) in Dubai November 30-December 12. The Protein PACT has organized or assisted with inviting expert speakers for six panels across five COP28 pavilions, including:

  • December 5 panel in the Food Pavilion, co-organized by IICA and the International Livestock Research Institute (ILRI) on the topic of sustainable and healthy livestock production systems
  • December 6 panel in the IICA pavilion, organized by the ​​Canadian Alliance for Net-Zero Agri-food on the topic of achieving net zero in agrifood systems
  • December 8 panel in the IICA pavilion, organized by the Protein PACT on the topic of principles, practices, and proof for animal agriculture driving climate and food security solutions
  • December 9 panel in the IICA pavilion, co-organized by IICA and ILRI on the topic of innovation and investment in livestock systems for climate change adaptation and  mitigation

VIII.  International Dairy Federation & European Dairy Association side event: How Animal Source Food Nourishes The World In Times of Climate Change.

IX. Vox: There’s less meat at this year’s climate talks. But there’s plenty of bull.  Meat and dairy are driving the climate crisis. Why won’t world leaders at COP28 do anything about it?

X.  Food Navigator: on The Emirates Declaration.  Food is finally at the top table but measurable targets are missing.  Over 130 prime ministers and presidents have today signed the Emirates Declaration at COP28 – a first of its kind commitment to adapt and ‘transform’ food systems as part of action on the climate crisis….

Comment: The Emirates Declaration on Sustainable Agriculture, Resilient Food Systems and Climate Action is the firsr statement out of this meeting.  It doesn’t mention fossil fuels (the elephant in this particular room) or meat.  But it does propose:

1. Financial and technical support for sustainable solutions, capacity building, infrastructure, and innovations for farmers, fisherfolk, and other food producers.while conserving, protecting and restoring nature.

2. Promoting food security and nutrition.

3. Supporting workers in agriculture and food systems whose livelihoods are threatened by climate change.

4. Strengthening water management .

5. Conserving, protecting and restoring land and natural ecosystems, enhancing soil health, and biodiversity, and shifting from higher greenhouse
gas-emitting practices to more sustainable production and consumption approaches, including by reducing food loss and waste and promoting sustainable aquatic blue foods.

As for how and when?

To achieve these aims – according to our own national circumstances – we commit to expedite the integration of agriculture and food systems into our climate action and, simultaneously, to mainstream climate action across our policy agendas and actions related to agriculture and food
systems.

In the meantime, consider these:

What will it take to stop the impending disaster?  This has to be #1 on the advocacy agenda.

Who knew? III. Corn-plus-soybean share of US crop acreage

Here’s my third Who Knew post of the week, this one an at-a-glance explanation of what’s wrong with the US food system, courtesy of FarmDocDaily.

In 1980 or so, corn and soybeans comprised about 20% each of total crop acreage.  Now it’s 30% each.

To bring this point home:

Recall that more than 40% of US corn is used to feed animals and another more than 40% is used to make ethanol.

Monoculture, anyone?  Lack of biodiversity?  Greenhouse gas emissions?  A focus on feed and fuel, not food?

Time to rethink the food system!

US industrial agriculture at a glance

A post on X (the site formerly known as Twitter) displayed this graph.

It comes from a policy report published on FarmDocDaily: Concentration of US Principal Crop Acres in Corn and Soybeans.

The bottom line: 30% of harvested acres is devoted to corn, and another 30% to soybeans.

These, of course, are largely genetically modified.

This is industrial agriculture at a glance.

And here’s one more, worth seeing again in this context.

Regenerative agriculture anyone?

Need a healthy snack? Try this!

My distant* but dearly loved cousin, Michael Kravit, sent this from Taiwan.  Seems like a really good idea.

I’m working on a book chapter on snack foods (for an updated edition of What to Eat) and I counted the number of feet of shelf space devoted to snacks—chips, crackers, cookies, toaster pastries, candies, etc—in the Ithaca Walmart: 4,100 linear feet, or 0.8 mile.

OK.  Some of them are nuts or dried fruit.  But the great majority?  Mostly ultra-processed and highly profitable to their makers.

*Definition of a distant cousin: he’s the grandson of my first cousin, which I think makes him twice removed.

Corn for ethanol? Not a good idea.

We grow lots of corn in the U.S.

  • Most of it is genetically modified, meaning that the potentially carcinogenic herbicide, glyphosate, gets dumped all over it in enormous quanitities
  • 40% of the corn is used to produce ethanol; this provides an incentive to grow corn in places where water is limited or land is poor.

One argument in favor of using corn for ethanol is that using ethanol for fuel reduces climate change.

But recent reports suggest that using corn for ethanol is a net loss for the planet.

Comment: Growing corn for ethanol is makes no sense at all.  It’s bad for land and water.  Dumping glyphosate also makes no sense.  We need an agricultural policy that promotes agroecology/regenerative agriculture/sustainability, and that promotes the health of everyone involved in production and consumption.

Corn for ethanol: a bad idea

If you want to know what’s wrong with the US food system, consider corn.

  • Hardly any of it is grown for food.
  • Most—half—goes for animal feed, domestic or exported.
  • One-third goes for ethanol fuel.

Let’s start with the big picture, courtesy of the National Corn Growers Association (FSI means Food/Seed/Industrial).

The USDA explains how much of total corn production ends up as ethanol fuel.

What’s wrong with this?  See The Conversation: The US biofuel mandate helps farmers, but does little for energy security and harms the environment.

If you’ve pumped gas at a U.S. service station over the past decade, you’ve put biofuel in your tank. Thanks to the federal Renewable Fuel Standard, or RFS, almost all gasoline sold nationwide is required to contain 10% ethanol – a fuel made from plant sources, mainly corn.

With the recent rise in pump prices, biofuel lobbies are pressing to boost that target to 15% or more. At the same time, some policymakers are calling for reforms. For example, a bipartisan group of U.S. senators has introduced a bill that would eliminate the corn ethanol portion of the mandate.

This article is worth serious attention for its discussion of the effects of corn growing on profits, carbon-neutrality, indigenous populations, and agriculture policy in general.

Or, to summarize in a corn cob (thanks to Mother Jones):

It’s hard to know where to begin to comment on this.

  • Many people in the world do not have enough to eat.
  • It would be better for people and the planet if we in industrialized countries ate less meat.
  • It would be better for people and the planet if we used fewer cars.

Growing corn for animal feed and automobile fuel makes no sense for human health or that of the enviroment.
