Since the introduction of the CSA concept in 1985 by Robyn Van En, the movement has spread throughout North America and has gradually come to include some 1,200 CSA farms.

The Robyn Van En Center is located in Wilson College, Pennsylvania, which operates the Fulton Farm CSA. According to the Fulton Farm CSA page, membership is open to anyone. Members contribute their financial and/or physical support to the farm, and in return receive the following privileges:

• Weekly produce pickup at the farm: a choice selection of seasonal farm produce.
• Access to wholesome fresh baked goods and sustainably produced eggs, cheese, and more!
• Pick-your-own options: berries, cherry tomatoes, flowers, herbs, and seasonal surplus items.
• Member picnics and workshops.
• Regular newsletter and recipes.
• 25% off at the Southgate Farmer’s Market (our booth only).

The Fulton Farm plants more food than its members can use which it uses to help finance its operations. However, if there is a food shortage, it's members needs will come first.

Recently, a study was done on the best way to distribute CSA food (note: PDF link) in terms of reducing the amount of co2 and "food miles" used. It was found that the best method was to deliver foods to members rather than having members pick the food up from a central location. Significant co2 savings would also be realized (2.7 times less co2) if a Toyota Prius was used to deliver the food.

Community Supported Agriculture is an excellent example of sustainable agriculture that comes with a long list of benefits (health, food safety, environment, economy, community) over traditional methods of agriculture. CSA also appears to be an evolving practice if the study eventually leads to food being delivered by Prius-driving farmers.
