Abstract


Recently, Algiers was evaluated as one of the worst life quality cities (The Economist, 2014). This assessment refers to the disintegration of environmental dimensions, especially the vegetal, as determinants of life quality in the city.

The strategic Hamma district is a significative example of this reality. Considered as the historic industrual hub, it suffers of soil contaminations; at the same time, it presents new empty land that must be reused, according to the ambitious capital’s image.

This site among others is considered as a part of the new "Strategic Plan of Algiers 2029", in order to turn it into an open eco metropolis by 2029. New visions of green urban initiatives are rightly recommended to introduce nature in the city, and to draw the main guidlines of new urbanity.

Through a multi-criteria analysis, consisting of different indicators: environmental, urban, economic and social; we propose to make a relevant diagnosis, in order to project ecological planning scenarios, for short and medium terms. This analysis allows us to evaluate the mutable potential of Hamma’s brownfields, into green spaces.

This paper specifies how brownfields can become ecological components of an urban green network to improve life quality in the city of Algiers. The reconversion of brownfiels of El Hamma with sustainable urban development approaches like the urban green grid, are able to provide good solutions to the current situation. Nonetheless, it opens perspectives to new ways of thinking about integrating vegetal dimension in urban projects.
