Identification des options et solutions de gestion pour les cas d'étude de WETwin

Abstract

WETwin is a research project supported by the European Commission under the Seventh Framework Program. Its overall objective is to enhance the role of wetlands in basin-scale Integrated Water Resources Management (IWRM), with the aim of improving the community service functions while conserving good ecological status. This report addresses formulation of management responses to the drivers, pressures and impacts on wetlands identified in case study sites. Within the WETwin conceptual framework a range of options are identified from which management solutions can be built up. In principle, each option can be carried out alone, but in practice, combinations of several responses are likely to be combined into comprehensive management solutions. Further this document identifies performance indicators used for the evaluation of the management solutions and describes a set of models and expert assessment tools used for this purpose. An overview of generic responses available for wetland management and rehabilitation is presented. Management responses are separated into groups of similar measures targeting specific wetland components. Such a grouping gives a clearer overview of possible measures, and facilitates transfer of these generic groups to other wetlands. A brief overview of the process of identifying, elaborating and combining management options into implementable packages of management solutions is then provided. Site-specific management options and solutions are presented for seven case studies: Ga-Mampa, Inner Niger Delta, Nabajjuzi, Namatala, Abras de Mantequilla, Lobau and Gemenc wetlands
