While doing my Master s Degree, I was invited to coordinate the implementation of the Madureira Park project. The proposal was mainly due to my involvement with environmental issues in the city of Rio de Janeiro during the elaboration of the Environmental Management Master Plan by the City Council and participation in the master s degree program at PUC-RIO on Urban and Environmental Engineering. I was given an urbanism project and the need to transform it became evident, inserting the environmental issues presented in the course and the measures approved by the Environmental Management Master Plan of the city of Rio de Janeiro which was newly approved. How does one recover a degraded area, improving the quality of urban life of the surrounding population of about 2.4 million inhabitants? The first transformation was to unify the spaces intended for the Park with the streets, thus expanding the usable area of the Park. Then define as the main guideline, a Socio-environmental Education Program as the base for the urban development, landscaping and architectural project. The objective was to establish an urban development project which besides improving the quality of life of the region, would allow users to live environmental experiences in public spaces that would surprise and inspire them, provoking the question of the meaning of what was being experienced. Respect for the user represented by the quality of the project, the materials used in the works and the conservation plan, convey the message of sustainability, raise the sense of belonging of the local population, and reduce the maintenance cost of the public space.
