Earth Watch: Agriculture and Water— How We Farm Makes a Substantial Difference

“Though the problems of the world are increasingly complex, the solutions remain embarrassingly simple.”

–Bill Mollison1

 

Droughts. Floods. Pollution. Water problems are everywhere—serious, complex issues that demand action. But as inundated as we are with news of impending doom, what about news of hope—the genuine, actionable kind? 

Cows grazing in a fieldMany of the water issues we face are worsened (or even caused) by the degenerative practices of conventional agriculture. Monoculture crops, bare fields, excessive use of tillage and synthetic chemicals, and concentrated animal feeding operations rob the soil of organic matter and biodiversity—essential ingredients for healthy function, including water infiltration.2 3 4 5 Agriculture is also one of the largest contributors to nitrogen and phosphorous pollution in water, a significant factor in the widespread occurrence of toxic algae blooms.6 7 8 It’s estimated that half the nitrogen and phosphorous applied to fields as fertilizer end up in the surrounding environment.9 Yet, this isn’t a requirement of modern food production. Regenerative agriculture can restore harmony and functionality to nature’s cycles and support resilient food-producing systems in a changing climate.10 11

The regenerative solution

Soil is one of agriculture’s most critical resources for improving drought and flood resilience and reducing water pollution.12 13 14 15 Healthy soil can absorb and retain much of its volume in water, and it only takes a one percent increase in soil organic matter to increase its water storage potential by approximately 20,000 gallons per acre.16 17 18 Imagine the potential impact this could have on California, where approximately 80 percent of the publicly developed water supply goes to agriculture.19 20 The National Resources Defense Council estimates that if farmers adopted cover crops and other regenerative practices on half of California’s field crop acreage, they could store an additional 10.9 billion gallons of water in the soil!21

Evidence from the farm

Regenerative farmers and ranchers practice the core principles of soil health adapted to the ecological context of their operations, building soil high in organic matter with the structure to support water infiltration and retention.22 23 Consider these outcomes from the farm: In early 2023, California experienced a series of heavy rainstorms after a drought, causing disastrous flooding and crop losses for many farmers.24 A Civil Eats op-ed highlighted the resilience of several regenerative operations in the state by contrast. Singing Frogs Farm in Sonoma County started spring planting on schedule despite receiving more than 13 inches of rain in just a few weeks.25 Additionally, although their lower fields flooded 11 of the last 15 winters, the excess water was absorbed and retained in the soil rather than causing severe damage.26 Similarly, Paicines Ranch, in San Benito County, told Civil Eats that their hilltop vineyard has experienced zero runoff since they began managing it regeneratively in 2017,27 and the soil could hold ALL the water the latest series of storms had unleashed.28

On the other side of the country, the Chesapeake Bay Foundation measured the environmental outcomes of converting conventional farmland on six farms in its region to rotationally grazed pasture, and the water pollution benefits were significant—nitrogen was reduced by 63 percent, phosphorous by 67 percent, and sediment by 47 percent on average.29

It makes economic sense

Adopting agricultural conservation practices commonly used in regenerative operations, like managed grazing, reduced tillage, and cover crops, is a smart investment—the Chesapeake Bay region's Watershed Implementation Plans for pollution reduction recommends these practices. It would also boost local economies by an estimated $655 million annually if the states sharing the watershed implemented them all. And some cost far less to implement than the conventional alternative. For example, it takes a $7.62 investment in forest buffers to reduce a pound of nitrogen, but it takes $2,350 in animal waste management systems to see the same result.30

In 2022, the top 10 commodities produced by U.S. farms included cattle, dairy products, hogs, broilers (chicken), and eggs.31 Support farmers raising these foods in a manner that regenerates the land. Put hope on the menu.
