Reintegration of Nature in the City of Algeria: Model Case of "Oued Kouba" District in Annaba (North-East of Algeria)

Today, in many countries around the world, urban planning research gives very little importance to the nature aspect. Thus, a reshaping of sustainable communities development strategy is being restructured to counteract the dangers of global changes related to globalization and technological and industrial development. In Algeria, successive phases of rural exodus that the country has lived have caused an overpopulation of cities generating excessive and rapid consumption of land with the gradual disappearance of green spaces. So, the city can constitute an ecosystem linked to many components including the district which represents a real model of sustainable discovery and invention. Annaba, 4th important city in Algeria and a large regional entity with a very significant human, natural and economic potential, is now currently exposed to the ecological problems due to various types of pollution. This observation has prompted us to undertake this project: it concerns the study of district named Oued Kouba which with these particular natural elements (sea, green spaces, wadis), represents one of the most appreciated districts of Annaba. However, despite its advantages, this district has many problems (pollution, poorly exploited green spaces, fragmentation of the green chain and that of the blue chain), which shows a real perturbation in the relationship of built environment to nature, and which requires a targeted and structured intervention. Our project consists in the restoration of nature in this part of Annaba, it is composed of two important steps; a brief analysis of the concept nature in the city, its evolution and its main characteristics followed by the main concepts that refer to it. A second diagnostic approach is composed of two parts, the Analysis / Diagnosis part which concerns the analysis of the architectural, sociological, economic and natural aspects, etc.) whose results are grouped in a AWOT table.
