ECOLOGICAL RESTORATION AND ECONOMIC REVITALIZATION OF INDUSTRIAL AREAS
Universidade de Lisboa
The industrial complexes of Lusalite and Gist-Brocades (Cruz Quebrada) were left to dereliction at the end of the past century, after the displacement of their activities to other areas, far from urban centres. The project for the revitalization of the site occupied by their settlements is part of a bigger discussion about the future of former industrial areas.
How could they be productive again? Which kind of development could they promote? How could they be integrated in the urban forms they are linked to?
The district of Cruz Quebrada, through the time, had got an evolution strictly connected to the dynamics and transformations of Lisbon. Located at the mouth of Jamor river, it was sought by the local aristocracy, thanks to its quietness and easy access to the beach (XVIII-XIX centuries). The rising of industrial plants in 1930s produced a progressive loss of quality of the entire area. Nevertheless, for 70 years these plants, Lusalite and Gist-Brocades, producing respectively roofing in fibre cement and yeast, represented the economic and urban motor of Cruz Quebrada. They can be considered as a part of a non-official industrial heritage, together with ‘Ramal do Estádio Nacional’, which is also included in the project area.
The idea of the project is to start from this historical context, being the negative consequences of the past industrial activities on water and soil and the need of a restoration of an ecological balance considered as a planning opportunity.
The revitalization of Cruz Quebrada will pass, then, by the ecological restoration of the riverine ecosystem of Jamor river, together with the set of a natural pool and several public spaces. They will work as a motor for different activities, being able to generate new economies linked to the production of intangible or uncountable goods, like leisure, culture or nature.
