The Global Water Partnership (2009a) developed a Handbook for Integrated Water Resources Management in Basins. The handbook identified sequential steps for basin management, including:
Outline broad policy goals as a vision for water management
Identify specific water management issues and problems
Evaluate potential solutions to resolve these issues
Implement the most appropriate strategy(s)
Evaluate the outcomes of implementing these strategies
Integrate the lessons learned from evaluating the outcomes into future work
An initial stage of this approach is revising future programs and activities based on past experiences in water planning and management, and incorporating new knowledge and information.
