A provocative discussion about flexible building but also about daring to demolish and retreat. 20 HOLY GRAIL FOR HEATING? In theory, all the homes in the Netherlands could be heated by extracting a single degree of heat from the Rhine. Is thermal energy from surface water an alternative to natural gas and other energy sources? Deltares is doing the research. 24 MICROPLASTICS Together, we produce 250 billion kilos of plastic worldwide every year. After it has been used, an enormous proportion is not collected properly, with all the inevitable consequences. How can Deltares help in the struggle with this many- headed monster? CREDITS Delta Life is published by Deltares, the Dutch innovation and research institute in the fields of water, subsurface and infrastructure. With independent research, Deltares is building the knowledge base that is urgently needed worldwide to keep deltas, coastal areas and river basins habitable. Knowledge development focuses on five themes: Flood Risk, Ecosystems and Environmental Quality, Water and Subsoil Resources, Delta Infra structure and Sustainable Delta Planning.

But they are also vulnerable: earthquakes, floods, terror and epidemics are ever-present threats. Disasters can be a fact of life but preparing for them is something we can control. Because you can organise resilience with things like good water management. 100 Resilient Cities helps: this initiative creates resilient cities that can take a punch. 'It's plain and simple: water management is not a choice,' says Michael Berkowitz, the 100RC president. 'Cities need to include it in their strategies and transform, or suffer the consequences.'
