Final answer:
Community-Supported Agriculture (CSA) programs (option A) are partnerships between farms and local consumers that contribute to sustainable agriculture by providing mutual support and sharing harvests.
Step-by-step explanation:
Programs that involve partnerships between food producers and local consumers, where farms provide shares of their harvest with community members who support the farm by working on or financing it, are known as Community-Supported Agriculture (CSA). CSAs play a crucial role in sustainable agriculture, a farming practice that aims to meet society's current and future food and textile needs without compromising the ability of future generations to meet their own needs. By investing in CSAs, community members can contribute to creating viable, sustainable food systems that are intimately connected with the health of their local environment.
