L’agriculture Urbaine A Antananarivo A La Recherche De La Durabilité. Une Étude De Cas

Abstract

Repeated food crisis occuring in increasingly shorter periods of time and their alarming proliferation throughout the world call for a rethinking of the management of production spaces. Furthermore, the significant advance of urbanization due to the increasing number of city dwellers and the decline of rual agricultural areas are leading specialists to consider integrating agriculture on the periphery or even in the very center of cities. In this context, this longitudinal study aims to highlight the pressures faced by urban agriculture in Antananarivo and to draw attention to the potential of its green spaces. Indeed, this type of agriculture faces numerous obstacles which, in the long term, seem to cast doubt on its sustainability. Thus, following studies and surveys conducted at the "tanin'anandrano" site of Ankaditoho-Maroho, it has been demonstrated that this agroecosystem, with its multiple potentialities, does not currently meet the criteria to be considerd a successful example of green development. In fact, the concept of urban agriculture in countries like Madagascar differs from the concept that is done in rich countries since it is a post-materialist concern, ecological urbanism being a logical continuation of post-industrializes urbanism.
