It is widely acknowledged that extreme events such as floods and droughts are an increasing challenge resulting in ‘Sponge city’ implementation in China and the rest of the world. In the speech ‘Overcoming Challenges in Delta’s Urban Water Management*’, Floris Boogaard** promoted the 25 years of Dutch experience with Sponge cities and presented new innovative technological methods for risk assessment and mitigation of extreme hydroclimatic events.
INXCES creates quick scan tools that will help decision makers and other actors to improve the understanding of cost effective implementation of water management solutions that reduce the negative impacts of extreme events. The INXCES approach optimizes the multiple benefits of urban ecosystems, thereby stimulating widespread implementation of nature-based solutions on the urban catchment scale.
**Floris Boogaard is professor Spatial Transformations at the Hanze University of applied sciences and partner of the INXCES project where new innovative technological methods for risk assessment and mitigation of extreme hydroclimatic events are developed.
