Such examples are also difficult to find in Central Asia due to the traditionally top-down approach to management, which doesn't mesh well with bottom-up initiatives (e.g. see the failure of many Water User Associations because of that). The one example for a well implemented sustainable development that comes to mind (there will be more, but that is the standout one to me) is the Khorezm project initiated by the ZEF in Bonn and the University in Urgench and supported by the UNESCO. It dealt with the economic and ecological restructuring of an intensively used agrarian landscape in a region affected by climate change, the desiccation of the Aral Sea, reduced water availability and soil salinization. It dealt with the sustainable use of limited resources and how that can benefit local livelihoods. And while it was a scientific project the results have been widely implemented in the region, which makes it a good best practice example.
