We Need a Green New Deal for Farmland
By Liz Carlisle
This opinion piece was originally published by Yes! Magazine on March 30, 2020.
As the coronavirus crisis has laid bare, the U.S. urgently needs a strategic plan for farmland. The very lands we need to ensure community food security and resilience in the face of crises like this pandemic and climate change are currently being paved over, planted to chemically raised feed grains for factory farm animals, and acquired by institutional investors and speculators. For far too long, the fate of farmlands has flown under the radar of public dialogue—but a powerful new proposal from think tank Data for Progress lays out how a national strategic plan for farmland could help boost economic recovery while putting the U.S. on a path to carbon neutrality.
The new Data For Progress memo builds on the Green New Deal resolution—a sweeping proposal to build out a carbon neutral economy, inspired by the package of Roosevelt administration social policy that lifted the United States out of the 1930s Depression and created the largest middle class in history. The Green New Deal, advocates say, would mobilize similar infrastructure and jobs programs, but with a focus on climate mitigation and resilience, and a more broadly construed focus on equity. (While the original New Deal met many goals expressed by organized labor, it failed to address racial inequality).
Yet this latest Data for Progress memo, published today, hearkens back several decades before Roosevelt's presidency. Reopening conversations that were front and center during Abraham Lincoln's time in the White House, the memo proposes one of the most promising strategies yet offered for meeting climate targets while building broad-based economic prosperity: a systematic national policy to facilitate land access for small farmers.
Lincoln’s Unfinished Business
Farmland ownership has not followed the path that President Lincoln envisioned, explains the memo's co-lead author Meleiza Figueroa, a Ph.D. candidate in geography at University of California, Berkeley and faculty-owner of the Birmingham-based Cooperative New School for Urban Studies and Environmental Justice. When Lincoln signed the Homestead Act in 1862, he promised small tracts of land to family farmers. Following emancipation, the Lincoln administration also promised "40 acres and a mule" to formerly enslaved Africans.
However, land speculators cheated from the beginning of the homestead era, gobbling up multiple claims under different names. And "40 acres and a mule" were never provided to emancipated slaves, as President Andrew Johnson rescinded the promise after Lincoln's assassination. Homestead claims trickled to a close in the early 1900s, and the federal government backed out of land policy, letting the market take its course. "When you look at the history of injustice in this country," Figueroa says, "it's all about land."
In the century-long absence of a coherent U.S. policy framework for farmland, Figueroa and her coauthors point out, several worrying trends have developed. For one, prime farmland has been paved over. According to the American Farmland Trust, 25.1 million acres of U.S. agricultural land—nearly the size of the state of Ohio—was converted to developed uses between 1982 and 2015.
Such land use change has significant climate implications. A 2012 University of California, Davis study that compared an acre of urban land to an acre of irrigated cropland found that the urban land generated 70 times as many greenhouse gas emissions. There's also an opportunity cost: Land-based carbon sequestration strategies like agroforestry and cover cropping can't be adopted if the land is under concrete.
Second, the memo points out, what farmland remains has become ever more concentrated in the hands of large farms and institutional investors. A mere 3.2% of U.S. farms account for 51% of the total value of the nation's agricultural production. Forty percent of U.S. farmland is rented, discouraging sustainable agricultural practices that require long-term management and secure land tenure. And farmers make up just 1.3% of the U.S. workforce.
"There's an assumption out there that this is just the forward march of progress," Figueroa says. " 'Who wants to be a farmer anymore?' Actually, a lot of people want to be farmers now—especially young people who are aware of the effects of climate change and also not satisfied by alienating office labor. Why not offer the opportunity for meaningful and gainful work that is beneficial to everybody, to people and planet?"
Racial Injustice Plays Out on the Land
The absence of a coherent U.S. land policy can be blamed for some of the current problems with farmland concentration, say the authors of the Data for Progress memo. But co-lead author Leah Penniman, founding co-director of Soul Fire Farm in Upstate New York, argues that the U.S. government has had a very influential de facto land policy over the past century, even if it wasn't articulated as such. "The very basis of U.S. land policy is rooted in the theft of land and the exclusion of people of color from land," Penniman explains. "This, of course, started with the genocidal stealing of almost the entire continent from the stewardship of Indigenous people … [and] throughout much of our history, there have been various state-level property ownership requirements that excluded people of color from being able to own property."
When people of color did amass property, Penniman says, they were targeted with violence.
"The Ku Klux Klan, the White Caps, and the White Citizens Council were responsible for lynching almost 4,500 people, many of whom were landowners, who they saw as having the audacity to get off the plantation and to want to stop sharecropping." The federal government also discriminated against black farmers through USDA programs, Penniman explains, resulting in a rapid decline of black farmers from 14% of the nation's farmers in 1910 to approximately 1% today.
Given that the average age of the American farmer is 57, and a significant share of the nation's farmland will soon change hands, Penniman and her co-authors argue, Americans have a short window of opportunity to rectify this unjust history while ensuring that farmland is conserved and that farmers have opportunities to combat climate change.
A Diverse Coalition for Reform
The diverse coalition mobilizing around these shifts to farm policy is notable: Contributors to the Data for Progress memo range from staffers at predominantly white farm state groups like National Family Farm Coalition and Family Farm Defenders to racial justice leaders like Penniman and Figueroa to academics focused on economic policy.
What these diverse constituencies share, the memo's authors explain, is that they've all gotten the short end of the stick of land consolidation and are struggling to survive. Ironically, many family farmers have accumulated significant land over the past generation or two but are less economically secure, as they've taken on debt to keep up with the treadmill of overproduction stimulated by current agriculture policy.
"We need to give current family farmers, who are mostly white, a lot of credit," Penniman says. "Nobody wants to be complicit in racism and in that kind of harm and exclusion. I think it's in our best interest as a nation not to pretend that we're all the same or that we all need the same policies, but to really look truthfully at what needs to change. And we've found that having these honest conversations in our communities often leads to common ground."
As for how to turn this common ground into policy change, the memo's authors outline a couple different pathways. The 'low hanging fruit' option, explains contributor Adam Calo, a researcher at the James Hutton Institute in Scotland, would be to expand three separate kinds of existing policies. For one, Calo believes, the U.S. should ramp up efforts to conserve farmland and protect it from development while limiting land investment by large corporations. Second, programs that incentivize farmers to use regenerative agricultural practices that combat climate change should be dramatically scaled up. The third and critical piece of this policy triad, Calo emphasizes, is equity: the U.S. must strengthen and enforce policies that ensure "Socially Disadvantaged Farmers" (the USDA's term for farmers subjected to racial discrimination) have equal access to all farm programs and particular set-asides to redress historic injustices.
More ambitious and transformative, the memo's authors suggest, would be to combine these objectives with a fully integrated land policy. Such a policy would include public land banks that could acquire land from retiring farmers and provide affordable access for farmers of color, new farmers, and farm cooperatives who pledged to use sustainable practices. It would also include a land commission, anchored by community-based institutions led by people of color, that would periodically assess that state of farmland access and make policy recommendations.
Good Stewardship at Scale
Figueroa is excited about these more far-reaching approaches, which she sees as opportunities to mobilize the underutilized climate response potential in Black and brown communities. "How many Oaxacan farmers are in apartment buildings right now?," Figueroa asks. "If you gave them land, they know what to do with it. It's not like they forgot what to do with it once they crossed the border."
But getting farmers on land isn't enough, Figueroa and her coauthors emphasize. A successful Green New Deal for farmland must help ecological farmers stay on the land—and thrive. Penniman points to the success of payment for ecosystem services policies like those in Costa Rica, where farmers are compensated for providing environmental benefits on behalf of society—benefits like maintaining pollinator habitat, preventing soil erosion, and sequestering carbon. We already have such programs in the U.S., including the Environmental Quality Incentives Program and the Conservation Stewardship Program, but they are funded at much lower levels than other farm programs that predominantly support industrial agriculture.
Overhauling farm programs by shifting current subsidies to instead compensate farmers for climate-beneficial practices—and establishing public procurement and supply management—would allow current family farmers to earn more money on fewer acres. At the same time, it would enable farmers to produce more human food (rather than biofuels and feed grain for factory farms) and provide more public benefits (such as drawing down emissions and improving watershed health). Remaining and degraded acres no longer needed by these now much more viable farms could be transitioned into land banks like those envisioned by the Data for Progress team, offering a just transition for both existing family farmers and landless farmers looking to contribute to climate mitigation and community food security by stewarding land.
"It's a win-win," Figueroa says. "People who want to put their labor into agriculture and struggling farmers who want support can actually join together as a community."

From the mythical minotaur to the mule, creatures created from merging two or more distinct organisms – hybrids – have played defining roles in human history and culture. However, not all hybrids are as fantastic as the minotaur or as dependable as the mule; in fact, some of them cause human diseases.
When Looking Through a Microscope Isn’t Close Enough.<p>For the last few years, <a href="http://www.rokaslab.org/" target="_blank">our team at Vanderbilt University</a>, <a href="https://www.researchgate.net/lab/Gustavo-Goldman-Lab" target="_blank">Gustavo Goldman's team at São Paulo University in Brazil</a> and many other collaborators around the world have been collecting samples of fungi from patients infected with different species of <em>Aspergillus</em> molds. One of the species we are particularly interested in is <a href="https://doi.org/10.1006/rwgn.2001.0082" target="_blank"><em>Aspergillus nidulans</em>, a relatively common and generally harmless fungus</a>. Clinical laboratories typically identify the species of <em>Aspergillus</em> causing the infection by examining cultures of the fungi under the microscope. The problem with this approach is that very closely related species of <em>Aspergillus</em> tend to look very similar in their broad morphology or physical appearance when viewing them through a microscope.</p><p>Interested in examining the varying abilities of different <em>A. nidulans</em> strains to cause disease, we decided to analyze their total genetic content, or genomes. What we saw came as a total surprise. We had not collected <em>A. nidulans</em> but <em>Aspergillus latus</em>, a close relative of <em>A. nidulans</em> and, as we were to soon find out, <a href="https://doi.org/10.1016/j.cub.2020.04.071" target="_blank">a hybrid species that evolved through the fusion of the genomes</a> of two other <em>Aspergillus</em> species: <em>Aspergillus spinulosporus</em> and an unknown close relative of <em>Aspergillus quadrilineatus</em>. Thus, we realized not only that these patients harbored infections from an entirely different species than we thought they were, but also that this species was the first ever <em>Aspergillus</em> hybrid known to cause human infections.</p>
Several Different Fungal Hybrids Cause Human Disease.<p>Hybrid fungi that can cause infections in humans are well known to occur in several different lineages of single-celled fungi known as yeasts. Notable examples include multiple different species of <a href="https://doi.org/10.1002/yea.3242" target="_blank">yeast hybrids</a> that cause the human diseases <a href="https://rarediseases.info.nih.gov/diseases/6218/cryptococcosis" target="_blank">cryptococcosis</a> and <a href="https://www.cdc.gov/fungal/diseases/candidiasis/index.html" target="_blank">candidiasis</a>. Although pathogenic yeast hybrids are well known, our discovery that the <em>A. latus</em> pathogen is a hybrid is a first for molds that cause disease in humans.</p>
(Left) Candida yeasts live on parts of the human body. Imbalance of microbes on the body can allow these yeasts, some of which are hybrids, to grow and cause infection. (Right) Cryptococcus yeasts, including ones that are hybrids, can cause life-threatening infections in primarily immunocompromised people. Centers for Disease Control and Prevention<p><a href="https://doi.org/10.1371/journal.ppat.1008315" target="_blank">Why certain <em>Aspergillus</em> species are so deadly</a> while others are harmless remains unknown. This may in part be because <a href="https://doi.org/10.1016/j.fbr.2007.02.007" target="_blank">combinations of traits, rather than individual traits</a>, underlie organisms' ability to cause disease. So why then are hybrids frequently associated with human disease? Hybrids inherit genetic material from both parents, which may result in new combinations of traits. This may make them more similar to one parent in some of their characteristics, reflect both parents in others or may differ from both in the rest. It is precisely this mix and match of traits that hybrids have inherited from their parental species that <a href="https://www.nytimes.com/2010/09/14/science/14creatures.html" target="_blank">facilitates their evolutionary success</a>, including their ability to cause disease.</p>
The Evolutionary Origin of an Aspergillus Hybrid.<p>Multiple evolutionary paths can lead to the emergence of hybrids. One path is through mating, just as the horse and donkey mate to create a mule. Another path is through the merging or fusion of genetic material from cells of different species.</p><p>It is this second path that appears to have been taken by our fungus. <em>A. latus</em> appears to have two of almost everything compared to its parental species: twice the genome size, twice the total number of genes and so on. But unlike other hybrids, which are often sterile like the mule, we found that <em>A. latus</em> is capable of reproducing both asexually and sexually.</p><p>But how distinct were the parents of <em>A. latus</em>? By comparing the parts contributed by each parent in the <em>A. latus</em> genome, we estimate that its parents are approximately 93% genetically similar, which is about as related as we humans are with lemurs. In other words, <em>A. latus</em>, an agent of infectious disease, is the fungal equivalent of a human-lemur hybrid.</p>
How A. Latus Differs From its Parents.<p>Elucidating the identity of closely related fungal pathogens and how they differ from each other in infection-relevant characteristics is a key step toward reducing the burden of fungal disease. For example, we found that <em>A. latus</em> was three times more resistant than <em>A. nidulans</em>, the species it was originally identified as using microscopy-based methods, to one of the most common antifungal drugs, <a href="https://www.drugbank.ca/drugs/DB00520" target="_blank">caspofungin</a>. This result provides a clear example of the potential importance of accurate identification of the <em>Aspergillus</em> pathogen causing an infection.</p><p>We also examined how <em>A. latus</em> and <em>A. nidulans</em> interact with cells from our immune system. We found that immune cells were less efficient at combating <em>A. latus</em> compared to <em>A. nidulans</em>, suggesting the hybrid fungus may be trickier for our immune systems to identify and destroy.</p><p>In the midst of the COVID-19 pandemic, our quest to understand <em>Aspergillus</em> pathogens is becoming more urgent. Growing evidence suggests that <a href="https://doi.org/10.1111/myc.13096" target="_blank">a fraction of COVID-19 patients are also infected with <em>Aspergillus</em>.</a> More worrying is that these <a href="https://doi.org/10.3201/eid2607.201603" target="_blank">secondary <em>Aspergillus</em> infections</a> can worsen the clinical outcomes for those infected with the novel coronavirus. That being said, we stress that little is known about <em>Aspergillus</em> infections in COVID-19 patients due to a lack of systematic testing, and none of the infections identified so far appear to have been caused by hybrids.</p><p>So, when it comes to hybrids, some are fantastic (the minotaur), some are helpful (the mule) and some are dangerous (<em>Aspergillus latus</em>). Understanding more about the biology of <em>Aspergillus latus</em> may help in our understanding of how microbial pathogens arise and how to best prevent and combat their infections.</p>

World Environment Day: A Time to Consider the Planet We’ll Return To, and Decide How to Care for It Going Forward
It's a different kind of World Environment Day this year. In prior years, it might have been enough to plant a tree, spend some extra time in the garden, or teach kids the importance of recycling. This year we have heavier tasks at hand. It's been months since we've been able to spend sufficient time outside, and as we lustfully watch the beauty of a new spring through our kitchen's glass windows, we have to decide how we'll interact with the natural world on our release, and how we can prevent, or be equipped to handle, future threats against our wellbeing.
