Community Supported Agriculture (CSA), sometimes referred to as Community Shared Agriculture, is a farming model that provides an upfront source of funding for individual farmers or groups of farmers. This approach allows farmers to raise working capital before the growing season by securing financial commitments directly from community members.
The CSA model is highly adaptable and can support a wide range of farm products—including vegetables, flowers, cheeses, breads, eggs, and pasture-raised meats and poultry. Rather than relying on large investments from a few stakeholders, CSA programs typically collect modest contributions from many individuals. This grassroots funding model not only strengthens the connection between consumers and producers but also fosters a sense of shared responsibility and engagement.
Participants, often called "members" or "shareholders," pledge in advance to help cover the farm's operating expenses, including the farmer’s salary. In return, they receive regular distributions—or shares—of the farm’s harvest throughout the season. This mutual commitment enables consumers to enjoy fresh, locally grown food while gaining insight into the agricultural process.
Importantly, CSA members also share in the inherent risks of farming, such as crop failures due to adverse weather or pest outbreaks. For farmers, this model reduces the financial uncertainty of the growing season, secures better prices for their products, and minimizes the time and expense associated with traditional marketing and distribution.
Four main types of CSAs have been developed:
- Farmer managed: A farmer sets up and maintains a CSA, recruits subscribers, and controls management of the CSA.
- Shareholder/subscriber: Local residents set up a CSA and hire a farmer to grow crops, shareholders/subscribers control most management.
- Farmer cooperative: Multiple farmers develop a CSA program
- Farmer-shareholder cooperative: Farmers and local residents set up and cooperatively manage a CSA.
Because of the flexible structure of Community Supported Agriculture (CSA), farmers can tailor membership terms to complement their existing market outlets. For example, a grower might schedule CSA pick-up days to alternate with farmers’ market days, helping to balance harvest workloads and manage inventory more efficiently. They may also offer options such as half-shares for smaller households or seasonal shares to align with specific crop availability.
In addition to flexibility, a CSA provides an important source of early-season income. This guaranteed revenue arrives at a time when farm expenses are typically high but production is still ramping up, offering valuable financial stability and reducing reliance on uncertain market sales.
Final Thoughts
Community Supported Agriculture represents more than just a sales strategy—it’s a philosophy rooted in transparency, sustainability, and mutual benefit. By participating in a CSA, both farmers and consumers become active stakeholders in local food systems. For farmers, the model offers critical funding, community support, and reduced marketing stress. For consumers, it’s an opportunity to invest in their health, environment, and local economy. As local food continues to grow in popularity, CSA models provide a powerful tool for strengthening farms and communities alike.

Description: Community-supported agriculture (CSA) is a growing business area for many Maryland producers. A CSA can bring in additional income to finance the operation, connect customers with your farm, and bring you a new customer pool, but this relationship depends on a useful contract that works for your business. Ashley Ellixson and Paul Goeringer, both with the Department of Agricultural and Resource Economics and the Agriculture Law Education Initiative, will walk you through some of the legal issues associated with CSAs, where operators mess up and highlight new resources to assist CSA operators in developing easy to understand contracts for their operations.
