Here’s the announcement:

The Food and Agriculture Organization of the United Nations (FAO) today launched its 2024 Statistical Yearbook, offering an in-depth overview of the most significant trends shaping global agrifood systems. This year’s edition highlights critical challenges, including increased temperatures over land, the ongoing global struggle with food insecurity alongside increasing obesity rates, and the environmental pressures faced by agricultural production….

The 2024 Statistical Yearbook is also available in a digital, interactive format and comes with a companion pocketbook, offering a clear reference to key data on agriculture, food security, and sustainability. It is part of FAO’s ongoing effort to improve data accessibility, complementing the FAOSTAT platform, which hosts the world’s largest collection of free agricultural statistics, covering over 245 countries and territories.

It’s got great graphics.  One example:

A few highlights:

• The value of global agriculture: $3.8 trillion in 2022.
• Proportion of global workforce employed in agriculture: a decrease from 40% in 2000 to 26% in 2022.
• Hunger remains persistent: In 2023, between 713 and 757 million people were undernourished, 152 million more people than in 2019.  Most are in Asia and Africa.
• Obesity is rising: More than 25% of adults in the Americas, Europe and Oceania are obese.
• Meat production increased by 55% from 2000 to 2022, with chicken accounting for the largest share of this rise. 
• Pesticides increased by 70% between 2000 and 2022, with the Americas accounting for half global pesticide use.
• Vegetable oils grew by 133 percent between 2000 and 2021, largely driven by an increase in palm oil production.
• Greenhouse gas emissions from agrifood systems rose 10% between 2000 and 2022, with livestock contributing to around 54% of farmgate emissions.
• Kuwait, the United Arab Emirates and Saudi Arabia are withdrawing each year 9 to almost 40 times their renewable freshwater resources available.

Comment: Food systems need immediate transformation to become healthier and more sustainable. 

Ronnie Cummins and André Leu.  The Regenerative Agriculture Solution: A Revolutionary Approach to Building Soil, Creating Climate Resilience, and Supporting Human and Planetary Health.  Chelsea Green, 2024.

I was asked to do a blurb for this one, and did:

This book is a testament to the vision of the late Ronnie Cummins.  His friend, André Leu, memorializes Cummins’ lifelong work with this overview of the demonstrable benefits of regenerative agriculture for everything in the book’s subtitle, and more.  Cummins’ case study on agave illustrates these benefits perfectly, making this book a useful as well as touching tribute.

This short book is a touchingly sentimental project.  It started out as Ronnie Cummins’ account of how to use agave fronds (which otherwise would be wasted), ground to the consistency of cole slaw and then fermented, for sustainable animal feed.

But Cummins died after writing only two chapters.  The publisher thought agave was too narrow a topic to make book length; it advised broadening the scope to regenerative agriculture with agave as a case study.  Leu, an old friend of Cummins’, took this on.

So there are really two books here, on two topics, by two different authors, in two distinct voices.  Even so, it works as a basic introduction to the benefits of regenerative agriculture for sustainability.

I think the agave example would be better as a monograph, but Cummins hadn’t done enough on it.  Too bad.  He was really excited about its possibilities.  Agave stores moisture from air and does not need much water to grow.

So I projected, if you could grow enough plants, in this case billions of agaves and companion trees, grow them large enough, and interplant them on millions and millions of acres of the world’s currently decarbonized and unproductive rangelands, you could conceivably draw down a critical mass of excess carbon from the atmosphere (where too much CO₂ contributes to climate change) and put in into the plants and trees aboveground, and into the soil belowground, where it belongs.  By greening the desert and the drylands you could dramatically increase soil fertility, retain and store rainfall, restore landscapes and biodiversity, reforest semi-desert areas, regenerate rural livelihoods, and eventually restabilize the climate.  I could hardly fall asleep.

This book is Cummins’ living memorial.

USDA has proclaimed August 4 – 10 as National Farmers Market Week.  I love farmers markets and I’m glad USDA is trying to promote them.

USDA publishes a directory of US farmers markets—7,033 listings.

It also lists

• Agrotourism sites (12,763)
• CSAs (Community Supported Agriculture (1,011)
• Food hubs (230)
• On-farm markets 1,937)

Farmers markets have a long history in the U.S.  The National Agricultural Library has a report on them published in 1948.

Its got all kinds of interesting information.

Here’s the most recent information I can find on growth in numbers.

This is progress.  Farmers markets are well worth support.

The Farmers Market Coalition provides resources and toolkits.

It also makes clear why they deserve support.  Famers markets:

• Preserve farmland
• Stimulate local economies
• Increase access to nutritious food
• Support healthy communtiies
• Promote sustainability

Besides, it’s fun to know your farmer, know your food.

Jennifer Grayson.  A Call to Farms: Reconnecting to Nature, Food, and Community in a Modern World.  Countryman Press, 2024.

What a great title! I did a blurb for Jennifer Grayson’s previous book, Unlatched: The Evolution of Breastfeeding and the Making of a Controversy, and was happy to have the chance to blurb this one too, not least because “A Call to Farms” is such a great title.  Grayson, as it happens, is one terrific writer.   

Here’s the new blurb:

In this deeply inspiring book, Jennifer Grayson examines the motives, practices, problems, and successes of a diverse collection of young small-scale farmers growing food sustainably and achieving enormous satisfaction and joy in the process. The farmers described in A Call to Farms, provide abundant reasons for hope in the future of food healthier for people and the planet as well as for its producers.  If you are looking for hope, here it is.

And here is a short excerpt capturing its essence:

A week into my first farm job, I realized it was the most joyful and fulfilling work I had ever experienced.  After two months of being outside all day, nearly every day, I felt the best—both physically and mentally—that I ever had in my life.  But the real transformation occurred as I began to meet and learn bout the new and driven farmers, graziers, and food activists emerging all over the country.  They hadn’t grown up in farming families; they came from backgrounds vastly underrepresented in agriculture; and many of them were far younger than I was, not to mention decades younger than the average American farmer.  I was awestruck by their intention and ingenuity.  They hadn’t turned to this way of life as some back-to-the-land fantasy.  They had chosen sustainable agriculture as a tactile way to effect environmental activism and food justice; for cultural reclamation; to reconnect to nature, food, and community; to live aligned with their values; to do, in the words of one farmer you’ll meet in this book, “something that means something.”

As I said, inspiring.  Get out there and farm!

Science Magazine has this editorial headline: Reverse EU’s growing greenlash**

I’m always interested in the USDA’s charts displaying food and agriculture statistics.  They help to clarify complicated issues.

Agricultural trade is particularly opaque, but here it is at a glance.

First, what the US exports:

Next, what we import:

What so bizarre here is that the categories are the same; we export and import the same kinds of products.

The biggest difference is in horticultural products, which the USDA defines as “plants that are used by people for food, for medicinal purposes, and for aesthetic gratification.”

Horticulture includes “specialty crops,” the USDA’s name for the plant foods humans eat (as opposed to feed for animals)—fruits, vegetables , nuts, and seeds.  To further confuse the matter, the USDA also lumps medicinal herbs, flowers, and Christmas trees in this category.

Never mind.  The bottom line is we import most of our fruits and vegetables.  This is because the US agricultural system focuses on feed for animals and fuel for automobiles.

Overall, here’s what all this does to the balance of trade:

We used to export more food than we imported.  Now, we don’t.

Shouldn’t our food system mainly focus on producing food for people?

Obviously, yes.

The USDA announced the latest data on the US agricultural system in a press release.  It summarizes the highlights:

• Number of farms: 1.9 million (down 7% from 2017)
• Average size: 463 acres (up 5%)
• Total farmland: 880 million acres of farmland (down 2%), accounting for 39% of all U.S. land.
• Revenues: $543 billion (up from $389 billion)
• Net cash income (less expenses): $152 billion.
• Average farm income: $79,790. A total of 43% of farms had positive net cash farm
• Percent farms with net income: 43%
• Farms selling direct to consumers: 116,617 with sales of $3.3 billion (up 16%)
• Farms with sales of $ 1 million or more: 105,384 (6% of all farms); they sell three-fourths of all agricultural products.
• Farms with sales of $50,000 or less: 1.4 million (74% of farms); they sell 2%.
• Percent of farmland used for oilseeds or grains: 32%
• Percent of farmland used for beef cattle: 40%
• Average age of farmers: 58.1 (up 0.6 years)
• Average age of beginning farmers: 47.1

The 2022 census information is so complicated to access that the USDA provides a video on the main site to explain how to use it.   This helps—a lot.

The site for the full report is here.   For the full report itself, go here.

Highlights are here.

Most of the data refer to industrial crops like corn and soybeans: feed for animals, fuel for automobiles.

If you want to know about food for people , you can looik at Table 36. Vegetables, Potatoes, and Melons Harvested for Sale: 2022 and 2017

All of this is in miserable-to-read tables.  Fortunately, The Guardian to the rescue: ‘America is a factory farming nation’: key takeaways from US agriculture census.

It provides illuminting charts based on the data.  For example:

What more to say?  Only that our agricultural system needs a major refocusing on smaller, diverse, regenerative farms producing food, as well as those producing animal feed.  We should not be growing food crops to produce automobile fuel.

A reader, Kris, sent me this query:

I hope in a future writing you can help sort out the mixed statements I’m reading  about how pasture-raised meat lines up in terms of environmental/climate change concerns, (particularly if it doesn’t involve extensive shipping). I’ve seen statements and studies on both sides of the argument and I’m having a hard time determining what is supported science vs wishful thinking or greenwashing marketing hype. (Links to 2 difference examples below).

I looked at her sources.

eFeedLink.com: Grass-finished beef operations found to have higher carbon footprint, study reveals. 

In a recent study published in the open-access journal PLOS ONE, researchers from the Breakthrough Institute in the United States, led by Daniel Blaustein-Rejto, present findings challenging the common belief that beef operations with lifelong grass-based diets have a lower carbon footprint than those incorporating grain-based diets, Phys.org reported.  Cattle raised on lifelong grass diets, termed “pasture finished,” have been traditionally thought to be more environmentally friendly. But the study delves into a more comprehensive analysis, considering factors beyond direct greenhouse gas emissions.

This took me to the PLoS ONE article:  Carbon opportunity cost increases carbon footprint advantage of grain-finished beef.

We assess the carbon footprint of 100 beef production systems in 16 countries, including production emissions, soil carbon sequestration from grazing, and carbon opportunity cost—the potential carbon sequestration that could occur on land if it were not used for production. We conduct a pairwise comparison of pasture-finished operations in which cattle almost exclusively consume grasses and forage, and grain-finished operations in which cattle are first grazed and then fed a grain-based diet. We find that pasture-finished operations have 20% higher production emissions and 42% higher carbon footprint than grain-finished systems.

Agricltural Systems: Impacts of soil carbon sequestration on life cycle greenhouse gas emissions in Midwestern USA beef finishing systems.

We used on-farm data collected from the Michigan State University Lake City AgBioResearch Center for AMP [adaptive multi-paddock] grazing. Impact scope included GHG emissions from enteric methane, feed production and mineral supplement manufacture, manure, and on-farm energy use and transportation, as well as the potential C sink arising from SOC [soil organic carbon] sequestration…This research suggests that AMP grazing can contribute to climate change mitigation through SOC sequestration and challenges existing conclusions that only feedlot-intensification reduces the overall beef GHG footprint through greater productivity.

Comment

I can understand Kris’s confusion.  The arguments about the environmental impact of grazing methods depend on assumptions about what needs to be measured.   There should be no argument, however, that pasture-raised animals are treated better and have better lives.  They enrich soil rather than polluting it, air, and water, as do animals raised in CAFOs (Confined Animal Feeding Operations).  When raised in a regenerative system, pastured animals replenish soil, cause carbon to be sequestered, and do other good things.  The downside?  Lower yields (but we overproduce meat anyway).  So, I’m all for pasture grazing.

The climate-change arguments depend on decisions about what gets counted; these vary depending on who is doing the counting.

Until everyone can agree on what has to be measured and included in climate-change assessments—and I see no sign of a movement to forge such an agreement—I’m voting for pasture-raised,.  Animal welfare and soil health are reasons enough.

Thanks Kris, for raising the issue so thoughtfully.
