This Handbook offers 'how to' ideas to help infrastructure practitioners identify good practice improvements in communication, starting with the World Bank's own expanding portfolio of dam projects. In-depth case studies prepared for this Handbook show the considerable scope, value added, and many practical reasons to link governance, sustainability, and communication aspects at all stages of the project cycle. The Handbook reflects a philosophy of continuous improvement in development practices. Improving communication in dam planning and management not only achieves consensus on imbedding anti-corruption measures in projects but also builds multi-stakeholder partnerships that are fundamental to advance the wider development effectiveness of large dams and creates synergy to combat poverty with sustainable infrastructure provision.
