This project's aim is to contribute to the field of geomorphology applied to planning and environmental management, by restoring the functional landscape in the lagoon border of the coastal plain of Barra da Tijuca, Rio de Janeiro.

The project's proposition is to guarantee the functionality of the restinga environment, associated to the mangrove in the lake border area, concerning interactive dynamics, aiming at the sustainability of its ecosystems in the actual situation of pressure due to urban occupational expansion.

The understanding of this particular context, based on geo-morphological guidelines, interacting with other dynamic processes in issue, has provided conditions for the development of techniques and management procedures set on perspectives that are dynamic and suitable to an urban environment located in a coastal plain.

The outstanding aspect of the project is the restoring of this environmental structure comprised of restinga vegetation associated to the recovery of the area's geo-morphological body of sand, named lagoon barrier. With the recovery of the sand barrier, its original paleo-form was restored, which made it possible to produce the pedological basis necessary to the implantation of restinga species, by way of ecological management of the soil, associated with pioneer re-vegetation, both spontaneous and induced.

This work takes as its study object the phyto-geo-morphological analysis that builds parameters for conduct on phyto-pedological structuring. This study consists of an activity set into a major purpose, which is the identification of the existing interaction between the coastal plain of Jacarepaguá and the surrounding massif which form its amphitheatre, providing elements for suitable planning of the use of soil in this particular area.
