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.
Industrial Farming Pollution
This review tracks fertilizer and manure from large-scale U.S. industrial farms into rivers, lakes, and the atmosphere. It shows how excess nitrogen and phosphorus from feedlots and vast corn/soy fields fuel toxic algal blooms, dead zones, and big chunks of our agricultural greenhouse gas emissions. In plain terms: concentrated factory farming is one of the main reasons so many lakes and coasts are turning green and lifeless.
Industrial Ag Pollution Overview
NRDC pulls together EPA and scientific data showing how large-scale industrial farms are major sources of water pollution, greenhouse gases, and soil degradation in the U.S. It highlights fertilizer runoff driving harmful algal blooms, manure lagoons leaking into groundwater, and air emissions from giant livestock operations. It’s a concise, accessible summary of why “Big Ag” is such a problem for land, air, and water.
Diversified Farms Boost Arthropods
This meta-analysis combined data from 98 studies worldwide. It shows that farms with crop diversity, flower strips, hedgerows, and mixed habitats support far more beneficial insects (pollinators, predators) than simplified industrial fields. The kind of mixed, messy landscapes you see at many small farms literally keep the living “infrastructure” of the ecosystem alive.
Diversified Farming Benefits
Here, scientists built a huge database of 5,000+ comparisons of diversified vs. conventional farming. They show that biodiversity almost always improves when farms diversify, and yields often hold steady. In other words, you don’t have to choose between wildlife and food. The right kind of diversified, often smaller-scale farming supports both.
Animal Feeding Ops Impacts
This systematic review looks across dozens of studies on large animal feeding operations (CAFOs). It finds consistent links between these factory farms and air pollution, water contamination, antibiotic resistance, and other hazards for nearby communities and ecosystems. It’s basically the scientific receipt for why “cheap” industrial meat carries a heavy environmental price.
Community Gardens and Stormwater
A study of New York City community gardens found they could soak up millions of gallons of stormwater each year that would otherwise flood streets and overload sewers. The 2024 policy brief summarizing this work makes the point clearly: small, soil-based food plots in cities act like sponges and filters, making extreme rain and pollution less damaging.
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.
