Meeting water governance challenges calls for a mix of well-integrated policy measures. This can be difficult to achieve in a context of fragmented responsibilities among various public actors as decisions are made at different territorial levels (national, regional, state, municipal, basin, etc.). Greater policy coherence among different institutions does not mean uniformity, but an attempt to create synergies between customised approaches. It requires mutually reinforcing co-ordination across government, departments and agencies for achieving the agreed-upon policy objectives, defining long-term strategies and adapting them to different contexts.
