Global society is confronted with various challenges: climate change should be mitigated, and society should adapt to the impacts of climate change, resources will become scarcer and hence resources should be used more efficiently and recovered after use, the growing world population and its growing wealth create unprecedented emissions of pollutants, threatening public health, wildlife and biodiversity. This paper provides an overview of the challenges and risks for sewage systems, next to some opportunities and chances that these developments pose. Some of the challenges are emerging from climate change and resource scarcity, others come from the challenges emerging from stricter regulation of emissions. It also presents risks and threats from within the system, next to external influences which may affect the surroundings of the sewage systems. It finally reflects on barriers to respond to these challenges. http://dx.doi.org/10.13044/j.sdewes.d6.0231 LinkedIn: https://www.linkedin.com/in/sabineeijlander/ https://www.linkedin.com/in/karel-mulder-163aa96/

'Versteende pleinen in steden zijn hitte-eilanden. Gemeenten willen daarom meer groen, maar dat is niet eenvoudig. In Groningen zijn nieuwe bomen geplant in een innovatief waterbergingssysteem. De Grote Markt ging op de schop.'

This book of examples suggests a variety of options for easy and accessible climate-resilient retrofitting of residential areas. The case studies for a set of common streets in the Netherlands will match urban settings in other countries. The examples show that effective climate-resilient retrofitting is usually quite simple and does not necessarily incur higher costs than traditional approaches, particularly in flat areas. An examination of typical Dutch urban street designs shows how climate resilience can be incorporated under different conditions while keeping costs down with retrofitting. We have investigated the effects of four retrofitting variants and specified their cost and benefits, applying a typology of common residential street characteristics. We sincerely hope these case studies inspire you to get started in your own town, city and country, because the climate is right up your street.
