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.
Willingness to Pay for Local Food
Pooling 86 estimates from 35 separate studies, this analysis found shoppers really do pay more for local food, typically an extra $1.70 to $2.08 per pound, with the premium even higher for local meat and dairy than for produce. The "local costs more" line isn't a myth. It's also apparently a price people choose to pay.
Economic Case for Land Conservation
This Harvard Forest report puts a number on something that's easy to hand-wave: every $1 of state money spent conserving New England's forests and farmland returns $4 to $11 in natural goods and services, from clean water to $570 million a year in avoided health care costs from cleaner air. Protecting the land isn't charity. It's one of the better investments the region makes.
Farmers Markets and COVID Resilience
When supply chains buckled in 2020, Michigan farmers markets didn't. Over 90% of vendors interviewed reported higher revenue that year than the one before, as shoppers who wanted to know exactly where their food came from turned to the people actually growing it. It's a real-world stress test of what a short supply chain is for.
Agritourism Regional Economic Ripple
Modeling agritourism spending across Tennessee, this study found every $1 spent at a farm generates $1.82 in total economic output for the state, as that money moves on to food service, recreation, and other local businesses. Buying a pumpkin at the farm instead of the grocery store keeps paying the neighborhood back long after you've left.
Agritourism Farm Income Growth
USDA's own farm census shows agritourism income hit $1.26 billion in 2022, up double digits from five years earlier, with well over half of U.S. counties reporting some agritourism revenue. Farm tours, u-pick days, and on-site sales aren't a side gimmick. They're becoming a real second income stream keeping small farms afloat.
CSA Marketing and Farm Viability
This national analysis of CSA farms found they tend to be small, run by younger or first-generation farmers, and often working rented land without the bargaining power of bigger operations. For exactly those farms, selling directly to members provides steadier income and a way in that conventional wholesale channels don't offer.
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.
Processed Foods and Health Outcomes
This massive review of 45 cohort studies found that higher ultra-processed food intake is consistently linked with higher risk of heart disease, type 2 diabetes, overweight/obesity, some cancers, and even common mental health disorders. The pattern is the same across countries: more factory food, more chronic disease.
Processed Foods and Cardiovascular Disease
In more than 100,000 French adults, higher intake of ultra-processed foods was associated with higher risks of overall cardiovascular disease, coronary heart disease, and cerebrovascular disease. The key takeaway: eating more factory-made, packaged meals and snacks shows up later as more heart problems.
Processed Food Consumption and Mortality
Using detailed diet records, this study found that higher ultra-processed food intake was linked to higher risk of death from all causes, especially from heavily processed meat/ready-to-eat products. It reinforces the idea that the problem is more than “too many calories.” The degree of processing itself matters.
Processed Diets and Excess Calorie Intake
In this controlled trial, the same people were fed two diets with identical calories and macros on paper: one ultra-processed, one made from minimally processed foods. On the ultra-processed diet they automatically ate about 500 extra calories a day and gained weight; on the whole-food diet they lost weight, without being told to restrict.
Poultry Intake and Heart Disease Risk
This meta-analysis pulled together 24 cohort studies looking at how much poultry people eat and their risk of heart disease, stroke, and early death. Overall, they found no strong evidence that typical poultry intake increases cardiovascular risk; if anything, the association was tiny and slightly protective at moderate intakes. The authors point out that how poultry is cooked (grilled vs fried vs ultra-processed) likely matters more than the bird itself.
Plant Foods and Heart Disease Reduction
This huge study across 18 countries found that people who ate more fruits, vegetables, and legumes had fewer heart attacks, strokes, and deaths overall. The sweet spot was around 3–4 servings per day in many settings, which is still “normal life doable,” not some extreme diet.
