摘要:The International Union for Nature Conservation has made consid erable efforts to bring sustainable Integrated Water Resources Man agement into practice through its Water and Nature Initiative. In doing so it faced major challenges such as institutional shortcom ings, underdevelopment of the civil society, and a lack of participa tion. In this paper we review the experiences of the International Union for Nature Conservation with the Water and Nature Initia tive in the Senegal River Basin. Findings indicate the International Union for Nature Conservation was able to open new spaces for sus tainable IWRM by cautiously lobbying at high administrative levels combined with community work on the ground.
