Until recently, we separated farmers and urban communities. Each had their own ministries, policy plans, cultures, knowledge and education institutes and even political parties. Now we accept that this division is gone in the Netherlands. Rural areas ceased to exist, and urbanity was found everywhere. Former rural areas were transformed into green spaces inside metropolitan areas. Farmers and peaceful villages woke up and saw themselves surrounded by cities. Even more: city dwellers became their neighbours. The time has come that we look upon farming and urbanised areas as an integrated system.

The crossroads of living in cities on the one hand and ageing of the population on the other is studied in an interdisciplinary field of research called urban ageing (van Hoof and Kazak 2018, van Hoof et al. 2018). People live longer and in better health than ever before in Europe. Despite all the positive aspects of population ageing, it poses many challenges. The interaction of population ageing and urbanisation raises issues in various domains of urban living (Phillipson and Buffel 2016). According to the Organisation for Economic Co-operation and Development (OECD 2015), the population share of those of 65 years old is expected to climb to 25.1% in 2050 in its member states. Cities in particular have large numbers of older inhabitants and are home to 43.2% of this older population. The need to develop supportive urban communities are major issues for public policy to understand the relationship between population ageing and urban change (Buffel and Phillipson 2016). Plouffe and Kalache (2010) see older citizens as a precious resource, but in order to tap the full potential these people represent for continued human development (Zaidi et al. 2013), the world’s cities must ensure their inclusion and full access to urban spaces, structures, and services. Therefore, cities are called upon to complement the efforts of national governments to address the consequences of the unprecedented demographic shift (OECD 2015). Additionally, at the city level there is a belief to understand the requirements and preferences of local communities (OECD 2015). An important question in relation to urban ageing is what exactly makes a city age-friendly (Alley et al. 2007, Lui et al. 2009, Plouffe and Kalache 2010, Steels 2015, Moulaert and Garon 2016, Age Platform Europe 2018)? Another relevant question is which factors allow some older people in cities to thrive, while others find it hard to cope with the struggles of daily life? This chapter explores and describes which elements and factors make cities age-friendly, for instance, on the neighbourhood level and in relation to technology for older people.
Urbanisation and climate change have an effect on the water balance in our cities resulting in challenges as flooding, droughts and heatstress. Implementation of Sustainable Urban Drainage Systems (SuDS) can help to restore the water balance in cities by storing and infiltrating stormwater into the subsurface to minimise flooding, restoration of groundwater tables to prevent droughts, lowering temperatures by evapotranspiration to fight heatstress. Urban planners and otherstakeholders in municipalities and water authorities struggle with implementing SuDS at locations where infiltration of water seems challenging. Questions arise as: can you infiltrate in countries as The Netherlands with parts under sea level, high groundwater table and low permeable soil? Can you infiltrate in Norway with low permeable or impermeable bedrock and frozen ground most of theyear? How do you find space to implement SuDS in the dense urban areas of Bucharest? These questions are answered by researchers of the JPI Water funded project INovations for eXtreme Climatic Events (INXCES).To answer the question on ‘can we infiltrate stormwater under worse case conditions?’, testing of the hydraulic capacity take place at rainwater gardens in Norway (Bergen and Trondheim) and (bio)swales in the low lying parts of The Netherlands. The first results show that even under these ‘extreme’ hydraulic circumstances the hydraulic capacity (or empty time) is sufficient to infiltratemost of the stormwater throughout the year.INXCES exchanged researchers on an international level, shared research results with stakeholders and sets up guidelines for design, implementation and maintenance of SuDS to promote the implementation of sustainable water management systems throughout the world.One of the tools used to promote SuDS is www.climatescan.nl, an open source online map application that provides an easy-to-access database of international project information in the field of urban resilience and climate adaptation. The tool is able to map several sustainable urban drainage systems as has been done for Norway, The Netherlands, Romania and other countries in the world.The tool is used for engagement with stakeholders within EU projects as INXCES and WaterCoG and resulted in international knowledge exchange on infiltration of stormwater under extreme climate and geohydrolic circumstances.
