Tropical plants of constructed wetlands for wastewater treatment on looking at human and social sciences
L'utilisation de végétaux tropicaux des marais artificiels pour l'assainissement d'un point de vue des sciences humaines et sociales
Résumé
Thus, choosing to plant local macrophytes species in CWs can be considered as an asset for the development of CWs, since it can be a part of global development projects which integrate cultural, social and economic characteristics. But, because of the ability of some macrophytes to accumulate toxic elements, human utilisation of CWs macrophytes has to be managed considering health damage potentiality. Spontaneous macrophytes diversity has to be appreciated for its key-role in the development of CWs in developing countries, not only from an ecological point of view, but also from cultural, social, sanitary and economic views.
