It is described the experience of a therapeutic garden project located in the vicinity of the Psychiatry Service of the Guillermo Grant Benavente Hospital (HGGB) in Concepción, Chile, led by the Non-Governmental Organization Rebrota (ONG Rebrota) based on the ecosocial perspective applied in people with mental health needs. It aims to analyze this Eco-social Occupational Therapy experience as a practical tool for the transformation of territories, allowing occupational therapists to understand the interaction between society and nature as a socio-ecological process that impacts different spheres of human beings, especially in social participation and mental health. Using the descriptive methodology of the Eco-social Entrepreneurship Process Model, we carry out a practical orientation of actions so that communities, inserted in their natural and cultural environments, can discover themselves reflexively, generating collective health processes. Eco-social Occupational Therapy develops practices that improve health and promotes the well-being of individuals, groups and/or communities, generating a positive impact on socio-ecosystems and building healthier, more inclusive, and sustainable communities. Eco-social Occupational Therapy is an invitation to generate research-action projects to mitigate the social impact on nature in a context of the climate crisis, where we find communities in the genesis of transcultural knowledge that allows us to develop a transformative praxis for good living in tune with our environment; while improving their well-being and participation, from a human rights and occupational justice perspectives.
