From its early discovery, mangrove has inspired ambivalent feelings among Westerners, ranging from delight to repulsion. It has been considered in turn as an unhealthy and hostile milieu, as a source of multiple resources or as a fragile, diversified and rich ecosystem. Management policies have also varied between extremes: from periods of degradation and conversion to periods of rehabilitation, restoration and protection. This contribution is centred on claims and conflicts over mangrove wetlands.First, through the case study of West Africa, we will show the very early (at least, the 15th century) multiple-use system controlled by peasant-fishermen communities, then the disruption of this remarkable and sustainable system with the 'white' penetration and colonization, ending with the recent process of rehabilitation, restoration and protection or 'heritage construct', that leads to conflicts.Second, this contribution will question the relevance of the concept of natural heritage, and set out the different interpretations and constructions that can be made from it: Which are the living objects designated as heritage? Who are the decision-makers, the stakeholders, the managers and/or the caretakers? Is mangrove a world heritage, a communal territory, a private capital or a public good?Third, to answer these questions, multidisciplinary approaches and new tools of management, not only integrated but also concerted, have to be developed. The diverse relationships in mangrove societies call for a variety of legal and management policies. In addition, a diachronic approach is necessary, investigating several time intervals (from a few years to eras).This contribution also discusses the implications of innovative tools such as the institutionalization of heritage and new ways of valuing nature, such as product labelling, eco-certification or ecotourism.
