Analyse participative des compromis entre les services écosystémiques de la zone humide dans la vallée de GaMampa, Province du Limpopo, Afrique du Sud. Leçons pour la gestion des ressources visant la durabilité de la zone humide

Abstract

The GaMampa wetland is located in the Olifants River catchment, in the Limpopo province of South Africa. It traditionally supports livelihoods, mainly through natural vegetation collection for food provisioning and raw materials. Since the 1990's, and most intensively from 2000 to 2005, it has been drained and its natural vegetation cut and burnt for subsistence maize cultivation. Its ecological integrity is jeopardized. The sustainability of the biological and geomorphologic features, as well as traditional provisioning and contemporary farming opportunities, are questioned. In a diagnosis of the situation, the research identified the reasons for this sudden change in wetland use. Starting from existing data on the case study, mostly developed under the CPWF and WETwin projects, this study analyzed the possible management responses to the problems of the wetland, emphasizing the need for integration of the wetland to the GaMampa valley resource system and thus the need for a global management of the resources aiming at wetland sustainability. This report provides details on management options and their alternatives for implementation, developed through consultation of stakeholders. It also proposes 4 sets of Management Solutions which can be used both by the WETwin project for future research purposes and the GaMampa valley decision makers to establish a management plan
