Why local food matters
Research, guides, and stories on farming, food systems, and the people growing our food in New England, written so you can use them, not just read them.
Regenerative Farming Profitability
Comparing regenerative and conventional corn farms across the Northern Plains, this study found regenerative fields produced 29% less grain but earned 78% higher profits. The reason wasn't yield. It was healthier soil and lower input costs. Growing less, on paper, paid the farmer more.
New England Food System Resilience
This regional study found that New England farms account for a striking amount of economic activity, yet direct farmer-to-customer sales are still just a sliver of what people spend on food (1.6% in Vermont, the highest in the region). The researchers set a goal of 30% regionally produced food by 2030. Every farm stand a shopper chooses over a supermarket chain nudges that number in the right direction.
The Economics of Local Food Systems
This USDA toolkit pulls together real-world case studies from across the U.S. and shows local governments how to measure the economic impact of farmers’ markets, food hubs, CSAs, and similar projects. The examples consistently show that when communities shift purchasing toward local producers, they see higher job creation, more local business income, and stronger tax bases than if the same money flows out to national chains and far-away suppliers. It’s basically a playbook for proving that local food is economic development, not charity.
Marketing Practices and Financial Performance of Local Food Producers
This USDA report looks at thousands of U.S. farms that sell through local channels like farmers’ markets, CSAs, and sales to schools and restaurants. It finds that farms focused on local buyers can be financially healthy at many different sizes—not just huge “big ag” operations. In plain English: selling locally is more than a feel-good move; it can be a real business model that keeps family farms alive and money circulating in nearby towns.
Impacts of Local Food System Producers
This New York study looked at different sizes of farms that participate in local food systems and modeled their ripple effects across the regional economy. It found that local-oriented producers can generate more local income and value added per dollar of output than larger, export-oriented farms. In simple terms: a dollar spent on food from nearby farms tends to “bounce around” locally more times (through wages, services, and other small businesses) than a dollar spent on food shipped in from big national suppliers.
Farmers Markets Stimulate Local Economies
This national nonprofit pulls together research from multiple states and sums it up in plain language: farms that sell locally create far more jobs per dollar of sales than farms that sell into large wholesale channels. One highlighted study shows that direct-marketing farms create almost three times as many local jobs per $1 million in sales as large wholesale growers. Because these farms buy most of their inputs locally and employ more people, every dollar you spend at a farmers’ market hangs around in your community longer instead of disappearing into a corporate balance sheet.
Short Supply Chains Guide
EU-funded research comparing multiple real-world short chains (farm shops, CSAs, box schemes, local fish clubs) with conventional supermarket chains. Case studies show that well-run SFSCs can cut transport emissions, packaging waste, and food loss, while improving freshness and reconnecting consumers with producers.
Short Supply Chains Assessment
Researchers here looked at farmers selling through farmers’ markets, CSAs, and other short chains. They show that these systems can cut packaging, reduce waste, and encourage more diverse, eco-friendly farming practices. For a shopper, buying from short chains tends to mean less hidden pollution behind the scenes.
Local Food Systems Review
This big review looks at 20 years of work on local food systems. It finds that local farms are particularly good at protecting farmland from sprawl, maintaining landscape diversity, and building climate resilience, even if transport emissions are only part of the story. For the environment, the big gains come from how local farms manage land, not just how far the food travels.
Local Food Sustainability Review
This LCA compares 428 short and long food supply chains across six European countries. On average, long chains can be more eco-efficient per kg because of highly optimized logistics, but there’s huge variation: some short chains perform very well. The key takeaway: “local” isn’t magically greener; when short chains are well-organized (grouped deliveries, minimal waste, efficient storage) they can match or beat industrial chains on energy use and emissions.
Intensification Raises Extinction Risk
This paper shows how the expansion and intensification of agriculture over the last 50 years has driven massive biodiversity loss worldwide. High-input, monoculture systems are a major reason so many species are sliding toward extinction. When you choose food from lower-input, more local producers, you’re pushing against that trend.
Intensification Harms Biodiversity
Working across European farms, this study shows that as agriculture becomes more intensive and uniform, both the number of species and the variety of “jobs” they perform in the ecosystem collapse. In practice, that means fewer pollinators, fewer natural pest-eaters, and more fragile ecosystems – the exact opposite of what you see on well-managed mixed farms.
School Gardens and Vegetable Preference
After a seven-month school gardening program, children could identify far more vegetables and reported liking them more, with the effect still holding a full year later. Growing a vegetable yourself, even as a kid, seems to change whether you're willing to eat it.
Farm Life and Childhood Asthma
Comparing two genetically similar farming communities, this study found essentially no asthma among Amish children, who live in close daily contact with farm animals, versus 20% among Hutterite children, whose farms are large and industrialized. The dust from a small, old-fashioned barn appears to train young immune systems in a way sterile, large-scale operations don't.
Home Cooking and Diet Quality
Tracking over 11,000 UK adults, this study found people who cooked at home more than five times a week ate significantly more fruits and vegetables, and carried less body fat, than those who cooked three times or less. Buying real ingredients only pays off if they actually make it into a pan. This is the data behind that assumption.
Fermented Foods and Gut Health
In this Stanford trial, adults who added foods like yogurt, kefir, and fermented vegetables to their diet for ten weeks saw their gut microbial diversity increase and markers of inflammation drop, effects a high-fiber diet alone didn't produce in the same short window. The ferment aisle at a farm stand isn't just a flavor choice.
Nutrient Loss in Stored Produce
Even under ideal refrigeration, packaged spinach lost nearly half its folate within eight days, and losses accelerated sharply at warmer, more realistic transport temperatures. The nutrients on a nutrition label assume the vegetable was tested the day it was picked. The longer produce sits in a truck or on a shelf, the less of that label is actually still true.
CSA Membership and Diet Quality
Among low-income families in subsidized CSA programs, 81.6% of adults and 82.9% of children met government vegetable-intake guidelines, compared to roughly 9-10% of Americans overall. Getting a weekly box of real produce, whether or not you chose it, seems to work better than telling people to eat their vegetables.
