River management faces many challenges world-wide including climate change, flood risks and the demand for more adaptive and 'ecosystem-based' systems. Instead of raising the dikes even higher, the new adage for river managers is to give the rivers more space to drain their waters. This in turn implies that river management will become a social business, with strong involvement of local communities. This book offers various examples and theories on how to avoid conflict and enter into fruitful relationships with river communities.
