Farmer's market alternative, in brief

CSA

Think of a program where you pay upfront for a seasonal share of a local farm's harvest—often delivered weekly. The initials stand for the community-supported model.

This clue hints at a shorthand term for "Community Supported Agriculture," a system where people buy shares of a farm's harvest in advance. "Farmer's market alternative" points to another way to get fresh, local produce without shopping at a market stall. The "in brief" signals that the answer is an abbreviation, which is why "CSA" fits perfectly.
