For instance, to harness water-related knowledge, policy makers can set up water information systems whereas solving conflicts over water resources allocation requires the active involvement of those affected to identify the appropriate trade-offs and build consensus. Indeed, 73% of participants surveyed concurred that existing mechanisms for stakeholder engagement are sufficient. Opinions converged that these tools have been successful to foster inclusive decision making, both formally by making stakeholder engagement more systematic, and informally by providing channels for stakeholders to contribute freely. This result shows that all tools are in place or at hand. It is then more a question of making them effective and outcome-oriented in practice than developing new instruments (Figure 5.4).
