Waste management continues to be a critical
environmental issue in cities. It impacts on the well being of the
population, the environment and the biodiversity. In the city of Maradi,
in Niger, more interest is given to the problem in order to understand
the whole waste management system. It is in this context that this study
is carried out to investigate on the role of ruderal flora on the
municipal solid wastes dumpsites and landfill sites in Maradi city. The
specific objectives are to determine the floristic diversity and
distribution of ruderal flora on the municipal solid waste disposal
sites, and to identify potential species that can play an important role
in the phytoremediation of these sites. In total, 65 species belonging
to 52 genera and 24 families were recorded. These species can be
categorised into two groups containing anthropic and nitrophilic species
according to the ascending Hierarchical Classification (AHC) at 25%
similarity. Characteristic species of the first group G1 are Amaranthus
viridis and Cucurbita pepo, and Datura innoxia and Cucumis melo for the
second group G2. Other ruderal species, namely Amaranthus spinosus L.,
Amaranthus viridis L., Celosia trygina L., Datura innoxia Mill., and an
introduced woody species, Cuphea hyssopifolia Kunth., found are not
included in the Maradi city list of species. Datura innoxia, Amaranthus
viridis and Amaranthus spinosus are species known to tolerate different
degrees of pollution and their ecology should be further study to better
understand how they can be used for phytoremediation on this kind of
sites.
