How Buying Local Preserves Farmland and Rural Economies

American farmland is disappearing. The USDA's 2022 Census of Agriculture counted approximately 880 million acres of farmland in the United States, down from approximately one billion acres in the early 1980s — a loss of more than 100 million acres over four decades. The primary driver of that loss in agricultural regions adjacent to cities and suburbs is conversion to residential, commercial, and industrial development.

Once farmland is developed, it almost never returns to agricultural production. The combination of infrastructure investment, increased land values, and fragmentation makes conversion essentially permanent.

Buying local food is not a complete solution to farmland loss, but it creates real economic conditions that make it more likely that farms stay in operation and that land stays in farming.

The Core Economic Problem: Development Pressure

Farmland near population centers is subject to enormous development pressure. As cities and suburbs expand, farm parcels on the fringe of urban areas often become worth more to a developer than they are as farmland, because the development value per acre vastly exceeds what the land can generate in agricultural income.

The American Farmland Trust (AFT), a nonprofit land conservation organization, tracks what it calls "Farms Under Threat" — farmland in the path of development pressure. Their 2018 analysis found that 11 million acres of the "best" agricultural land in the U.S. — land rated by USDA NRCS as prime or unique farmland — was in the highest-threat zones for conversion.

A farm that generates enough income to cover its costs, pay the farmer reasonably, and compete with the income return on the land's assessed value is a farm that can say no to a developer's offer. A farm operating at a chronic loss cannot.

How Direct-Market Sales Change the Math

The economic model of commodity agriculture — where a farm's revenue depends entirely on prices set by commodity markets — is hostile to small-scale farm viability near cities. A small farm cannot compete on price per bushel with large-scale commodity operations in the Midwest or Great Plains.

Direct-market agriculture changes the equation. When a farmer sells directly to consumers through a farmers market, CSA, online farm store, or restaurant relationship, they capture the full retail price rather than the commodity price. For many vegetables, eggs, and specialty items, the difference is substantial.

Example: A pound of conventionally marketed tomatoes might return $0.10–0.25 to the grower as a wholesale commodity. The same pound of tomatoes sold at a farmers market or through a CSA might return $1.50–3.00 to that same grower. That difference is not profit alone — it has to cover additional packaging, transportation, and time — but it fundamentally changes whether a small farm on 10 or 20 acres can be economically viable.

Direct-market farm revenue creates a pathway to viable farm income on acreages that would be unprofitable in commodity agriculture, which makes it possible for farms adjacent to population centers to compete with development pressure on their land.

The Local Economic Multiplier

Money spent at local businesses tends to recirculate in the local economy more than money spent at national chains or through e-commerce. This is the "local multiplier effect," and it applies to farm spending as well.

When you buy food from a local farm, the farm uses that revenue to pay farm workers who live in the community, purchase supplies from local businesses, pay property taxes that fund local schools and services, and invest in equipment from local dealers. Studies of agricultural economic multipliers vary, but the USDA Economic Research Service has documented that agricultural sales generate significant secondary economic activity in rural counties.

The American Independent Business Alliance has documented that locally owned businesses typically recirculate 3–5 times more money per dollar of revenue in their local communities than non-local businesses, because they use local services, employ local workers, and make local purchases.

Conservation Programs That Work Alongside Buying Local

Farmland preservation is also supported by conservation programs that directly fund land protection:

Agricultural Conservation Easements (ACE) — Administered by USDA NRCS, the Agricultural Conservation Easements Program pays landowners to permanently limit development on their land in exchange for a payment that reflects the difference between the land's full market value and its value under the easement restrictions. As of fiscal year 2023, USDA NRCS had protected more than 6 million acres through easement programs.

Purchase of Agricultural Conservation Easements (PACE) — Many states operate their own PACE programs in addition to the federal NRCS program. States like Maryland, Pennsylvania, Vermont, and Virginia have some of the oldest and most active state farmland preservation programs in the country.

Beginning Farmer programs — The USDA Farm Service Agency's Beginning Farmer and Rancher programs and NRCS programs explicitly support keeping land in farming by helping new farmers access land and capital.

These programs work best when farm businesses are economically viable — because a landowner is more likely to consider an easement that limits development if their farm income is sufficient that foregoing development value is acceptable.

Rural Communities and the Farm Economy

The decline of farm income and small farm viability does not only affect farms. Rural communities built around agricultural economies — their hardware stores, feed mills, veterinary practices, implement dealers, and grain elevators — depend on farm business activity. When farms consolidate or go out of business, the businesses that served them often follow.

The USDA Economic Research Service has documented persistent population decline and economic contraction in many rural counties where small and mid-scale farm operations have been replaced by large-scale operations requiring less local labor and fewer local services.

A robust direct-market farm economy — farmers markets, CSA programs, farm-to-restaurant relationships — keeps more farm businesses viable, which keeps more dollars flowing through rural and peri-urban communities.

What Your Purchasing Does

You cannot preserve farmland with your grocery budget alone. But the aggregate effect of consumer preference for local food matters:

• Farms with strong direct-market sales are more financially viable, which reduces development pressure on their land.
• Viable farms are more likely to pursue conservation easements that permanently protect their land.
• Farmer income from direct sales supports the economics of keeping land in agricultural production rather than selling to developers.
• Strong local food demand creates market conditions that attract the next generation of farmers to direct-market farming.

Buying local is not a silver bullet for farmland preservation. But it creates the economic foundation that makes all the other tools — easements, conservation programs, farm succession planning — actually work.

Farmland by the Numbers

• 880 million acres — total U.S. farmland as of 2022 Census of Agriculture (USDA NASS)
• 74 million acres lost — the net decline in U.S. farmland from 1982 to 2022
• 11 million acres — prime and unique farmland in high-threat development zones (American Farmland Trust, 2018 analysis)
• 6 million+ acres — farmland protected by USDA NRCS easement programs through FY2023
• 2 million farms — the approximate number of U.S. farms as of the 2022 Census; this has declined from nearly 6.5 million farms counted in 1920

The trend line is long and clear. The question for each generation is what choices — as buyers, as communities, and as policymakers — slow or reverse it.
