YSK in the U.S., you can buy produce directly from black farmers and they will ship it to you. It can cost less than your supermarket and will piss off people in power.
Black Farmers Index
This is great. Is there something similar for finding local farms regardless of race?
You could try researching CSAs in your area. There are a few near me that sell farm shares with weekly pickup of seasonal veggies during harvest season. I'm in northern California, and our rate is under $20 per week after we split it with another couple. We usually receive more veggies than we would buy during a weekly grocery store trip, plus our farm let's everyone pick fresh bouquets each pickup as a nice bonus.
I'd love to learn more about the ones in NorCal. I'm in the peninsula.
CSA huh
Yup, stands for community supported agriculture. They're often called co-ops or farm shares, but I think CSA is the industry term that you'll have most luck with when searching around online.
Farm co-ops I think focus on local farms.
