Berry Gersonius is working as a freelance consultant at the intersection of learning and adaptation for building resilience. Berry has developed his view on the concept of resilience at IHE-Delft (former: UNESCO-IHE), where he worked as a (senior) lecturer in flood resilience for 13 years. He also completed his PhD dissertation at UNESCO-IHE and Delft University of Technology. He has gained broad experience with the application of flood resilience in Dordrecht. The Island of Dordrecht was a pilot study of the Dutch Delta Programme on resilient flood risk management. Since 2013, Berry provides expert advice to the City of Dordrecht on how to embed resilience building actions into their policies and regulations. An example of this is the (minimum) set of requirements used for construction tenders. Berry has been involved in many European and international projects, such as for the EU Framework 7 programme (FP7), the Interreg North Sea Region (NSR) programme, the Australian Cooperative Research Centres (CRC) programme and the Dutch and Bangladesh Delta Programme. He is currently involved in 4 Interreg NSR projects (BEGIN, FAIR, Jomopans and C5A) and 1 Horizon 2020 project (SHELTER). He also facilitates two national learning networks that help organisations and peers learn from each other on building resilience. These networks are the City Deal on Climate Adaptation and the network KANS.
