Urban agriculture, as a crucial component of green urbanism, plays a pivotal role in the integrated development of urban and rural areas, the optimization of urban and rural spatial resources, and the pursuit of sustainable development. Citizen farms, primarily operating under the community supported agriculture (CSA) model, have emerged and developed gradually in recent years as a distinctive form of urban agriculture in China. However, due to the vast geographical diversity, differing natural resources, varying geographic environments, economic development levels, and cultural customs across different regions of China. Accordingly, the advantages, challenges, and issues faced by CSA citizen farms in different regions also vary. The Pearl River Delta, the most rapidly developing region in China since the reform and opening-up policy, lacks substantial research on local CSA citizen farms. This paper takes the Pearl River Delta as an example and, considering the local development conditions analyzes the advantages and values of CSA citizen farms. It provides an overview of the status of CSA citizen farms in the region, classifies them based on their characteristics, identifies current development issues and barriers, elucidates the positive impact of CSA on the Pearl River Delta, and ultimately proposes future development strategies and prospects for CSA citizen farms in the region. The aim is to encourage sustained and positive growth of CSA citizen farms in the Pearl River Delta and provide valuable insights and references for the development of citizen farms and sustainable urban agriculture in other regions.
