Territorially-based participative analytical methodologies taking the environmental question and work into consideration are essential for effective primary health care. The study analyzed work and environment-related processes in the primary health care area and their repercussions on the health of workers and the community in a rural city in Ceará, whose economy is based on agriculture for export,. It sought to redeem the area and the proposal of actions focused on health needs by the social subjects through the making of social, environmental and work-related maps in workshops within the framework of action research. Examining the situation from a critical perspective, based on social participation and social determination of the health-disease process with regard to the relations between production, environment and health, was the most important step in the participative map-making process, with the qualitative material interpreted in light of discourse analysis. The process helped identify the health needs, the redemption of the area, strengthened the cooperation between sectors and the tie between the health of the worker and that of the environment, and represented an advance towards the eradication of the causes of poor primary health care services.
