Could This Ancient Jewish Practice Be a New Tool for Sustainable Agriculture?
Schoolchildren gather around a seemingly neglected garden bed at , a Jewish farm and educational center in Berkeley, California. Educator Ariela Ronay-Jinich shows the students that while the plot appears abandoned, it鈥檚 actually the farm鈥檚 most fertile patch of soil. The children dig their hands an inch beneath the surface and uncover a thriving community of worms and insects, including a foot-long earthworm.
Ronay-Jinich explains that the plot has been set aside for shmita, a Jewish farming practice dating back to Biblical times, that lets the soil rest for one year after every six years of farming (the next shmita year is September 2021鈥22). Intended to express gratitude for abundance and share one鈥檚 fruits of labor with the less fortunate (in accordance with laws that require farmers to forgive debts and leave field corners for the needy to glean), the practice derives from rules laid out in : 鈥淎nd six years thou shalt sow thy land, and gather in the increase thereof; but the seventh year thou shalt let it rest and lie fallow, that the poor of thy people may eat; and what they leave, the beast of the field shall eat.鈥
Many farms leave portions of the land fallow for a season. But, says Lucy Zwigard, a farmer at Urban Adamah who has also practiced agroecology in France, 鈥渨hat sets shmita apart from typical crop rotations is that it invites us to reimagine our fundamental relationship with the land. Winter and , for instance, are still production-based and 鈥榖usiness-as-usual.鈥 Shmita is a full-stop, reset, rethink of cultivation.鈥
While shmita is not widely practiced on commercial farms, even in Israel, its age-old ideals have gained traction in the United States over the past decade as the field of spiritual ecology鈥攁n understanding of environmental degradation as rooted in spiritual malaises such as greed and apathy鈥攈as taken off.
鈥淛ewish community farms,鈥 including 笔丑颈濒补诲别濒辫丑颈补鈥檚 , Illinois鈥 , and San Diego鈥檚 all employ the shmita practice as they follow Talmudic agricultural law. These organizations are part of a modern movement with a reawakened interest in what they call 鈥渆arth-based Judaism,鈥 which approaches climate change and environmental sustainability through a lens of ancient wisdom.
Even secular farms, such as the , incidentally employ shmita-style philosophies in their work; its farm incorporates the idea of rest and follows a seven-year rotation plan in its vegetable fields, based on the seven major plant families.
In light of 听辞苍 , allowing soil to go fallow poses an age-old, no-maintenance way to regenerate soil at any scale. Industrial agriculture and desertification have together depleted global grasslands and prairies to the extent that, according to Rattan Lal, director of Ohio State University鈥檚 ,聽the world鈥檚 cultivated soils have lost聽 in the soil as it has entered the air as atmospheric carbon dioxide.
In addition to reducing carbon outputs like burnt fossil fuels, humans can draw carbon back into the ground by restoring organic soil matter as a 鈥.鈥 Through photosynthesis, plants intake carbon from the air and feed it to deep soil organisms, and . Shmita could complement other 聽and carbon sequestration techniques鈥攊ncluding 鈥攂y that simply letting land rest can alone increase soil fertility and thus sequester carbon.
Many manifestations
Shmita dates back thousands of years, to a time when growing food was more central to human life than it is today. Farmers prepared for several years prior to store food and plant enough perennials to eat during shmita. During that year, they only harvested as much as they needed to eat at any time, and otherwise rested from agricultural labor. (Farmers were the first professionals to take a 鈥渟abbatical year,鈥 which later extended to clergy and scholars.) However, the financial and operational logistics make whole-farm shmita much less feasible on today鈥檚 farms.
Few farms practice shmita in Israel today, and when they do, ultra-Orthodox Jews eat domestically grown perennials but import annual produce from non-Jewish farmers abroad. (Observant Jews believe that shmita law only applies in Israel, so while they eat any food grown internationally by non-Jews, they cannot eat Israeli-grown annuals.)
Even though the laws of shmita don鈥檛 officially apply in America, many farms鈥攔anging from for-profit farms to urban synagogues鈥 educational gardens and rural retreat centers鈥攈arness its wisdom in creative ways, says Shani Mink, a co-founder of the and a member of the .
鈥淎t the 聽in Connecticut, they designate a plot of their land during shmita year as one without fences, meaning that anyone is welcome to come and harvest,鈥 Mink said. 鈥淢aryland鈥檚 scaled back their farming, took a break from their fellowship program, and spent the full year observing the land and composing a master ecological plan that would both grow the community and nurture the biodiversity of the 180-acre property.鈥
鈥淲e donate 70 percent of our produce, and we sell 30 percent of it as聽.鈥
笔丑颈濒补诲别濒辫丑颈补鈥檚 only has one fallow bed, but co-founder Nati Passow says, 鈥渨e manifest shmita鈥檚 values in various other ways.鈥 Their garden started as a vacant lot and they eventually took down the fences, bought the lot, and made it a public space for children as well as for community programs. They also started donating produce to , a food justice organization with a location across the street.
鈥淏y literally taking down fences, we created inclusive public space,鈥 Passow says. 鈥淲e have been planting more fruit trees, berries, and perennials, and during the last shmita year, we restricted ourselves from storing surplus harvest鈥攂ecause that creates an accumulation of wealth鈥攕o that we could only take what we needed at the moment.鈥 Passow also notes that a couple of years ago, the Jewish Farm School held a forum about shmita and, to his surprise, Christians in particular from around the country were interested in learning about and implementing the practice in their congregations and gardens.
San Diego鈥檚 Coastal Roots Farm exemplifies another revised shmita observance. 鈥淔or what we call 鈥榓bove-ground growing,鈥 we plant seedlings and organic matter into , place them on top of a small shmita bed, and give them drip irrigation so that the ground below can rest,鈥 says Sharone Oren, the farm鈥檚 education manager.
鈥淥ur farm relies on continual grants鈥攚e donate 70 percent of our produce, and we sell 30 percent of it as , so we cannot pause operations for one whole year,鈥 Oren explains. 鈥淚nstead, we use the shmita plot鈥攈alf of which [is planted with] perennials鈥攁s an educational tool, which we arranged as a meditation labyrinth for visitors to wander through and ponder its principles.鈥
Listening, engaging, and resting with the land
The Jewish sustainability organization , headquartered at the Isabella Freedman Center, launched the and the as resources for the next shmita year.
In addition to a history and textual interpretations of shmita, Hazon鈥檚 provides an appendix of practical agriculture techniques that combine Jewish law with design principles. Though permaculture is a relatively new approach鈥攆irst developed by David Holmgren and Bill Mollison in the late 1970s鈥攎any Jewish farmers find its methods compatible with shmita鈥檚 principles.
One section, for example, argues that a 鈥減erennial-based food system鈥濃攚hich includes trees, shrubs, mushrooms, and wild (uncultivated) crops鈥攍eads to a healthier and more resilient food ecology. Perennial plants 鈥渋nvest more into their own plant body (since they are long-lived), while annuals invest more in producing seed (since they live only through their seed production),鈥 according to the book. They therefore have longer roots that tolerate drought and access more nutrients in the soil, stronger bodies that resist diseases and pests, and single planting that reduces soil disruption.
Yigal Deutscher, a farmer, permaculture designer, and author of , says that shmita is more than just producing food and undoing the shortcuts that industrial agriculture has taken to make unsustainable profits, he says. 鈥淚t is a whole systematic approach of regenerative agriculture. You cannot just buy a permaculture book and be all set. Every land has its own agreements with the people who tend it, and each has a different mythology and ecological relationship that has taken generations upon generations to learn.鈥
No matter if a farmer is Jewish or secular, uses crop rotations or no-till methods, harvests wild annuals or only perennials, Deutscher says, they apply shmita if they listen to and engage in a deep ecological relationship with the particular land and its needs.
Perhaps shmita could be the next sustainable agriculture wave, or as environmental psychologist and activist Dr. Mirele B. Goldsmith foresees, 鈥淚n a world inspired by shmita, there will be no early deaths from filthy air, no oil spills, no devastated mountains and collapsing coal mines, no toxic wastewater from fracking, no contaminated nuclear plants, no oil-fueled wars, and no climate change.鈥 Despite various interpretations, one conviction is ubiquitous: periodic rest is essential for one鈥檚 field and, by extension, the planet鈥檚 health.
