Value Chain of the Main Agricultural Products of Escarcega, Campeche, Mexico

The agricultural value chain is a fundamental analytical approach for understanding the organization, generation, and distribution of value in agri-food systems. The municipality of Escárcega, Campeche, has a strong agricultural focus based primarily on staple crops such as maize (Zea mays L.) and rice (Oryza sativa L.), which play a central role in the local economy and regional food security. The objective of this study is to analyze the structure and functioning of the value chain for Escárcega's main agricultural products through a comprehensive review of scientific and documentary literature. The results reveal a value chain dominated by primary production, with a low level of agro-industrial processing, limited producer organization, and a strong dependence on intermediaries for marketing. These conditions limit value capture by local producers. It is concluded that strengthening the value chain requires comprehensive strategies focused on productive organization, technological innovation, and access to differentiated markets.
